Source thread: https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/
Pages covered: 1–25 (360 posts, Nov 2022 – Jan 2026)
Primary subjects: 2023+ Civic Type R (FL5), with some Si and Integra Type S (DE5) reports
---
## 1. Driver seat creak/squeak (NHTSA recall on early FL5)
- **Symptom:** Squeaking/creaking when rocking side to side into the bolsters, or in cornering. Loud enough to be unbearable for many owners.
- **Location:** Driver seat — primarily the bolster/inner-seat-frame area; also seat rails and pivot points.
- **Suspected cause:** Improperly welded driver seat cushion frame assembly. Honda issued a stop-sale and safety recall on 2023-03-30 for affected 2023 CTR units (cars roughly under VIN 600 / first wave). Non-recall cases tend to be dry contact points or loose bolts.
- **Fixes that worked:**
- Honda safety recall — driver seat cushion frame replaced under warranty. recall notice https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-857563/
- Dealer disassembled seat, heavily lubricated pivoting points and track rails — no parts replaced. Persistent fix in some cases. DIGITALVIC https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-848304/, follow-up 2 months later https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-854297/
- Inner seat frame replacement, requiring full seat disassembly and an upholstery specialist (sublet by Honda dealer). Ministry https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-846529/
- Lower seat frame replacement after upper-frame swap didn't resolve. Bsnyder6 https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-856464/
- Si owner had lower seat frame replaced after finding loose mounting bolts. sackofcheese https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-849656/
## 2. Infotainment / center-dash buzz (TSB)
- **Symptom:** Buzzing or rattling from behind the infotainment screen, typically worse at higher RPM or in cold weather.
- **Location:** Center dash, behind the head unit.
- **Suspected cause:** TSB exists for the 2022 Civic — improper torque on screws behind the display, plus insufficient felt tape. Also TCU mounting hardware in some cases.
- **Fixes that worked:**
- **Screw-tightening procedure (works without disassembling dash):** Tap dash next to infotainment to confirm metallic buzz. Remove trim cover behind screen, unplug harnesses. Loosen the two retaining screws by 3–4 turns, then re-tighten alternately a half-turn at a time, tapping after each turn until the sound disappears. johnny.silva7 step-by-step https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-862516/
- **TSB procedure (felt tape under display):** Remove dashboard center trim and the four screws holding the display, slide display out, apply felt tape per Honda's PDF (linked below), reassemble. mujoa full write-up + linked TSB PDF https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-869253/
- **TCU unit fix** (when buzz behind infotainment isn't solved by the above): Remove TCU, its metal mounting bracket, and the four metal screw-fastener clips. Apply foam tape around the two connectors. Reassemble. ganzi2 https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-891123/
- Some owners reported the dealer's "infotainment TSB" fix did not resolve their buzz, and the rattle was actually from the rear-view-mirror plastic above (see #3).
## 3. Plastic cover behind/around rear-view mirror
- **Symptom:** Buzz/rattle that *sounds* like it's coming from the center dash or infotainment but actually originates above. Pressing up on the plastic immediately silences it.
- **Location:** Plastic housing directly behind/around the rear-view mirror mount.
- **Suspected cause:** Loosely clipped trim and/or the Honda Sensing camera cover; gap between windshield and plastic.
- **Fixes that worked:**
- Press up on the plastic to confirm. TypeRGirl's discovery post https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-867781/
- Pop the cover off, stuff foam padding inside. elusiveaura https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-868765/, Bazgab https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-868785/
- Remove the camera/mirror housing, tape the loose clips in place from underneath, then apply black tape around the housing edges so it's not visible when reassembled. mujoa write-up, step 1 https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-869253/
- Replace the camera-cover clips with double-sided tape, or wedge napkins between the cover and the windshield. GWonder https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-907234/
## 4. Glovebox rattle
- **Symptom:** Rattle from the glovebox, often at higher RPM or rough roads.
- **Location:** Top edge of glovebox door, where it meets the dash.
- **Suspected cause:** Insufficient padding where the closed glovebox door contacts the surrounding dash.
- **Fixes that worked:**
- Apply a foam strip on the inside top of the glovebox at the opening so the door no longer taps the dash. Bandit_TypeR https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-904623/
- Dealer master tech applied foam insulation tape and reseated the airbag. GreyhoundR6 https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-902003/
## 5. Lower-left panel below glovebox (knee area)
- **Symptom:** Rattle from lower portion of the dash, passenger side. Often misdiagnosed as glovebox or center-stack rattle.
- **Location:** Hollow plastic cavity in the panel under the glovebox, between the glovebox itself and the kick panel.
- **Suspected cause:** Internal vertical ribs vibrating against unsupported plastic. Sometimes paired with broken kick-panel clips from the factory.
- **Fix that worked:** Stuff "yoga mat" foam (folded over to ~4 layers thick, ~2"×8") into the cavity from underneath, working blind by feel. Hidden once installed. TypeRD instructions and Amazon link to foam https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-857151/
## 6. Passenger knee-airbag panel / footwell
- **Symptom:** Rattle in passenger footwell area, particularly in R+ mode or rough roads.
- **Location:** Plastic panel that covers the knee airbag / center-passenger footwell.
- **Suspected cause:** Panel tapping against a large white plastic box behind it; in some cars one of the white retention clips is missing.
- **Fixes that worked:**
- Pull the panel down (clipped on, just yank it), apply sound-deadening material on the inside surface where it contacts the white plastic, reattach. Bandit_TypeR https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-905150/
- Felt tape all around the panel edges. mujoa step 3 https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-869253/
## 7. A-pillar / dash corner rattle
- **Symptom:** Rattle from A-pillar area, worst around 2,600 RPM.
- **Location:** Top of A-pillar near the airbag stamp; also near the lower A-pillar/dash join.
- **Suspected cause:** Pillar trim contact points dry/unfelted; one A-pillar tab is easy to break, so DIY removal is risky.
- **Fixes that worked:**
- Confirm by stuffing craft foam into the top seam (near the airbag stamp) — silences the rattle. Then have the dealer reseat the A-pillar with felt tape on every contact point (often quicker/cheaper than full replacement, which is on backorder). Bonito https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-865028/
- Tesa tape on the bottom section so the trim is press-fit instead of loose, plus foam tape along the whole edge. ganzi2 https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-905674/
## 8. Seat-belt height-adjuster buzz (B-pillar)
- **Symptom:** Buzz right next to the driver's ear, B-pillar area; common across the 11th-gen Civic line.
- **Location:** Seat-belt height-adjuster mechanism on the B-pillar.
- **Suspected cause:** Slack in the slider mechanism that lets it vibrate within its housing.
- **Fixes that worked:**
- **Easiest:** Press down on the top of the adjuster (without pushing the release button). Tightens the slack and silences the buzz. May need to be re-done occasionally. TypeRD repeated recommendation https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-886567/, confirmed Jan 2026 https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-1022436/
- Lower the adjuster all the way down to its lowest position. JAMSXR translation of original tip https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-856012/, Rhorn https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-862504/
- Move adjuster to the next notch when it starts buzzing. Shankmeyster https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-886541/
- Honda part **06993-SA5-000 (Felt Wool)** — apply inside the B-pillar trim. Midori Garage https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-862511/
- **Note:** A *slightly-down window* can mimic this exact rattle. Try pulling the window switch up first. TDC50 https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-863663/
## 9. Seat-belt retractor buzz (lower B-pillar)
- **Symptom:** Buzz coming from front passenger side, harder to localize than the height-adjuster buzz; intermittent on driver side too.
- **Location:** Seat-belt retractor down by the floor under the lower B-pillar trim.
- **Fix that worked (DIY, ~10 minutes):** Remove lower B-pillar trim. Unbolt the 10mm bolt holding the retractor mounting bracket to the chassis. Place sound-deadening material between the chassis and bracket. Add sound-deadening to the white plastic housing on the retractor. Reattach. Bazgab full procedure https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-909107/
## 10. Driver-door rattle (loose harness clip)
- **Symptom:** Rattle from driver door area, worse with bass.
- **Location:** Inside the driver door, around the smart-key / exterior-door-handle harness.
- **Suspected cause:** Factory-loose harness connector — the clip securing it to the door was found detached. Likely a factory miss.
- **Fix that worked:** Peel back the upper-left portion of the door liner to access the harness connector. Reattach the clip into its hole. The window must be down to reach. Stanleywinthrop https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-978051/
## 11. Side-mirror rattle when closing door
- **Symptom:** Rattle from outside mirror only when door is slammed shut.
- **Fix that worked:** Press on the mirror glass while closing the door. type r fanatic https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-886538/
## 12. Steering wheel airbag click/creak
- **Symptom:** Metallic ping or click from the steering wheel — at low speeds over bumps, or when turning past ~90°.
- **Location:** Inside the steering-wheel airbag cover.
- **Suspected cause:** Loose airbag-assembly springs/seating.
- **Fixes that worked:**
- Have the dealer remove the airbag assembly and reseat it. Confirmed fix when same procedure was done during an Alcantara wheel install. Bonito https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-888162/
- Dealer applied felt tape to a bunch of contact points around the airbag seating — improved but not eliminated. Bonito update https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-862457/
## 13. Defroster / dash-top air-vent rattle
- **Symptom:** Rattle from one of the air vents (front-right defroster, top-dash passenger, or driver-side door vent), louder under acceleration.
- **Suspected cause:** Loose vent-housing fitment.
- **Fixes that worked:**
- Remove vent and add sound deadening behind it. Chilly613 referenced video https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-863930/
- Some owners (e.g. Bonito) report no fix yet despite removing the vent and trying felt tape and foam stuffing. report https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-861426/
## 14. Headliner buzz at 3,500–4,000 RPM
- **Symptom:** Buzz from headliner above driver seat at a narrow RPM band.
- **Suspected cause:** One or more factory clips not seated.
- **Fix that worked:** Tap the headliner with your fist near the apparent source — clips pop into their slots. Doesn't need to be hard. TypeRD https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-884905/, IsaiahGF confirmed by tapping near rear-view mirror https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-884951/
## 15. Trunk/hatch latch "clink"
- **Symptom:** Metallic clink from the trunk on bumps; sounds exactly like a loose license plate.
- **Suspected cause:** Insufficient tension on the trunk latch — the trunk door is bouncing against the latch.
- **Fixes that worked:**
- Move the rubber bump stops on both sides of the trunk door downward to increase preload. TypeRD's resolution after 18 months https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-916339/
- Temporary: Wrap the latch with a few layers of electrical tape for more friction (lasts ~6 weeks per re-wrap). Motpeds https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-917079/
## 16. Hatch interior-handle screws
- **Symptom:** Rattle from rear of cabin/hatch.
- **Suspected cause:** Loose screws on the interior trim handles inside the hatch.
- **Fix that worked:** Pull back hatch trim, find and tighten the two loose screws on the interior handles. AbeTypeR https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-895154/
## 17. Rocks in the rear diffuser
- **Symptom:** Metallic-tap rattle from rear when hitting bumps; mimics a loose license plate.
- **Suspected cause:** Small rocks collecting between the plastic diffuser and the metal heat shield via the diffuser's drainage holes.
- **Fix that worked:** Pressure-wash the diffuser drainage holes from below. TypeRD https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-857498/
## 18. Rear-bumper / underbody rattle (unresolved single-source)
- **Symptom:** Loud metallic rattle from rear on abrupt bumps. Distinct from #15 and #17 above.
- **Status:** Owner exhausted obvious checks (license plate, cargo, spare-tire kit, diffuser rocks); dealer couldn't replicate. Resolved only after dealer accidentally damaged the rear bumper and replaced the entire bumper assembly. TypeRD's saga https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-895031/
- **Likely cause (suspected, not confirmed):** Loose wiring harness inside the bumper or a heat shield clip.
## 19. Window rattle when fully up
- **Symptom:** Buzz from the left window when fully closed.
- **Suspected cause:** Window not fully seated against the seal.
- **Fix that worked:** Pull up briefly on the power-window switch — the window moves 1/8"–1/4", not enough to see a gap, and the rattle stops. TDC50 — also relevant for misdiagnosed seat-belt rattles https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-863663/
## 20. "Ticking" from outside trim (B-pillar exterior)
- **Symptom:** Ticking right at driver's ear at idle and on smooth roads — intermittent and weather-dependent.
- **Suspected cause:** Shiny exterior trim piece on the outside of the car.
- **Fix that worked:** Honda replaced the trim piece, **part 72470-T24-T01**. FiveSeven108 https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-1022439/
## 21. Engine-bay firewall rattle
- **Symptom:** Rattle from engine bay on rough roads.
- **Location:** Top-center firewall plastic brackets/clips.
- **Status:** Reported but unresolved as of Dec 2025. cryptolime https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-1015117/
## 22. AWE Touring exhaust rattle
- **Symptom:** Rattle at certain RPM/resonance with AWE Touring exhaust installed.
- **Two known causes:**
- Muffler too far back, rubbing rear heat shield. **Fix:** Move muffler forward; or trim/bend the heat shield away from the piping with a pry bar. UJX https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-885638/
- Broken internal weld inside the Touring muffler — warranty issue with AWE. UJX https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-885636/
## 23. HVAC whirring at low fan speeds (likely normal)
- **Symptom:** Whirring/whining from the HVAC, audible only at parked-low-fan setting; goes away at higher speeds.
- **Status:** Reported on both the FL5 (~2k mi onset) and the Integra Type S (~1,200 mi onset, post-warranty visit). Likely shared HVAC components and probably normal. No fix proposed in thread. FL5 report https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-857756/, ITS confirmation https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-857847/
## 24. Wastegate whistle (normal)
- **Symptom:** Whistle when letting off throttle in 3rd or 4th gear.
- **Status:** Normal — electronic wastegate, same noise as on the FK8. Aftermarket exhaust muffles it somewhat. elusiveaura https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-863430/

## Cross-cutting tips that came up repeatedly
- **Dealer service caveat:** Multiple owners (and one Honda service manager in the thread) warn that having the dealer pull the dash apart often introduces new rattles via broken clips and loosened panels. DIY foam/felt fixes tend to produce better outcomes for minor rattles.
- **303 Protectant trick:** TypeRD reports that some "rattles" are actually two tightly-fitted plastic pieces *rubbing* against each other (stick-slip), and a small amount of 303 Protectant sprayed into the seam (with surface excess wiped) damps the noise without dismantling anything. post https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-868792/
- **Diagnostic approach:** Drive with a passenger who can press on suspected panels while you drive. Many owners spent weeks chasing a symptom that turned out to be in a different location than where it sounded like.
- **First-wave FL5 risk:** Cars in roughly the first 600 VINs / first wave appear to have the worst rates of seat creaks (improper welds — recall) and other early-build issues. Later-wave cars (e.g. car #2880, #2888) report few problems.
- **Material consensus for DIY fixes:** Felt tape, Tesa tape, foam tape, "yoga mat" foam folded over, and Siless/Dynamat sound-deadening sheets are the recurring tools owners use successfully.

## 7. A-pillar / dash corner rattle
- **Symptom:** Rattle from A-pillar area, worst around 2,600 RPM.
- **Location:** Top of A-pillar near the airbag stamp; also near the lower A-pillar/dash join.
- **Suspected cause:** Pillar trim contact points dry/unfelted; one A-pillar tab is easy to break, so DIY removal is risky.
- **Fixes that worked:**
- Confirm by stuffing craft foam into the top seam (near the airbag stamp) — silences the rattle. Then have the dealer reseat the A-pillar with felt tape on every contact point (often quicker/cheaper than full replacement, which is on backorder). Bonito https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-865028/
- Tesa tape on the bottom section so the trim is press-fit instead of loose, plus foam tape along the whole edge. ganzi2 https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-905674/
## 8. Seat-belt height-adjuster buzz (B-pillar)
- **Symptom:** Buzz right next to the driver's ear, B-pillar area; common across the 11th-gen Civic line.
- **Location:** Seat-belt height-adjuster mechanism on the B-pillar.
- **Suspected cause:** Slack in the slider mechanism that lets it vibrate within its housing.
- **Fixes that worked:**
- **Easiest:** Press down on the top of the adjuster (without pushing the release button). Tightens the slack and silences the buzz. May need to be re-done occasionally. TypeRD repeated recommendation https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-886567/, confirmed Jan 2026 https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-1022436/

- **Note:** A *slightly-down window* can mimic this exact rattle. Try pulling the window switch up first. TDC50 https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-863663/
## 9. Seat-belt retractor buzz (lower B-pillar)
- **Symptom:** Buzz coming from front passenger side, harder to localize than the height-adjuster buzz; intermittent on driver side too.
- **Location:** Seat-belt retractor down by the floor under the lower B-pillar trim.
- **Fix that worked (DIY, ~10 minutes):** Remove lower B-pillar trim. Unbolt the 10mm bolt holding the retractor mounting bracket to the chassis. Place sound-deadening material between the chassis and bracket. Add sound-deadening to the white plastic housing on the retractor. Reattach.

## 10. Driver-door rattle (loose harness clip)
- **Symptom:** Rattle from driver door area, worse with bass.
- **Location:** Inside the driver door, around the smart-key / exterior-door-handle harness.
- **Suspected cause:** Factory-loose harness connector — the clip securing it to the door was found detached. Likely a factory miss.
- **Fix that worked:** Peel back the upper-left portion of the door liner to access the harness connector. Reattach the clip into its hole. The window must be down to reach. Stanleywinthrop https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-978051/
## 11. Side-mirror rattle when closing door
- **Symptom:** Rattle from outside mirror only when door is slammed shut.
- **Fix that worked:** Press on the mirror glass while closing the door. type r fanatic https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-886538/
## 12. Steering wheel airbag click/creak
- **Symptom:** Metallic ping or click from the steering wheel — at low speeds over bumps, or when turning past ~90°.
- **Location:** Inside the steering-wheel airbag cover.
- **Suspected cause:** Loose airbag-assembly springs/seating.
- **Fixes that worked:**
- Have the dealer remove the airbag assembly and reseat it. Confirmed fix when same procedure was done during an Alcantara wheel install. Bonito https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-888162/
- Dealer applied felt tape to a bunch of contact points around the airbag seating — improved but not eliminated. Bonito update https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-862457/
## 13. Defroster / dash-top air-vent rattle
- **Symptom:** Rattle from one of the air vents (front-right defroster, top-dash passenger, or driver-side door vent), louder under acceleration.
- **Suspected cause:** Loose vent-housing fitment.
- **Fixes that worked:**
- Remove vent and add sound deadening behind it. Chilly613 referenced video https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-863930/
- Some owners (e.g. Bonito) report no fix yet despite removing the vent and trying felt tape and foam stuffing. report https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-861426/
## 14. Headliner buzz at 3,500–4,000 RPM
- **Symptom:** Buzz from headliner above driver seat at a narrow RPM band.
- **Suspected cause:** One or more factory clips not seated.
- **Fix that worked:** Tap the headliner with your fist near the apparent source — clips pop into their slots. Doesn't need to be hard. TypeRD https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-884905/, IsaiahGF confirmed by tapping near rear-view mirror https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-884951/
## 15. Trunk/hatch latch "clink"
- **Symptom:** Metallic clink from the trunk on bumps; sounds exactly like a loose license plate.
- **Suspected cause:** Insufficient tension on the trunk latch — the trunk door is bouncing against the latch.
- **Fixes that worked:**
- Move the rubber bump stops on both sides of the trunk door downward to increase preload. TypeRD's resolution after 18 months https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-916339/
- Temporary: Wrap the latch with a few layers of electrical tape for more friction (lasts ~6 weeks per re-wrap). Motpeds https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-917079/
## 16. Hatch interior-handle screws
- **Symptom:** Rattle from rear of cabin/hatch.
- **Suspected cause:** Loose screws on the interior trim handles inside the hatch.
- **Fix that worked:** Pull back hatch trim, find and tighten the two loose screws on the interior handles. AbeTypeR https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-895154/
## 17. Rocks in the rear diffuser
- **Symptom:** Metallic-tap rattle from rear when hitting bumps; mimics a loose license plate.
- **Suspected cause:** Small rocks collecting between the plastic diffuser and the metal heat shield via the diffuser's drainage holes.
- **Fix that worked:** Pressure-wash the diffuser drainage holes from below. TypeRD https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-857498/
## 18. Rear-bumper / underbody rattle (unresolved single-source)
- **Symptom:** Loud metallic rattle from rear on abrupt bumps. Distinct from #15 and #17 above.
- **Status:** Owner exhausted obvious checks (license plate, cargo, spare-tire kit, diffuser rocks); dealer couldn't replicate. Resolved only after dealer accidentally damaged the rear bumper and replaced the entire bumper assembly. TypeRD's saga https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-895031/
- **Likely cause (suspected, not confirmed):** Loose wiring harness inside the bumper or a heat shield clip.
## 19. Window rattle when fully up
- **Symptom:** Buzz from the left window when fully closed.
- **Suspected cause:** Window not fully seated against the seal.
- **Fix that worked:** Pull up briefly on the power-window switch — the window moves 1/8"–1/4", not enough to see a gap, and the rattle stops. TDC50 — also relevant for misdiagnosed seat-belt rattles https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-863663/
## 20. "Ticking" from outside trim (B-pillar exterior)
- **Symptom:** Ticking right at driver's ear at idle and on smooth roads — intermittent and weather-dependent.
- **Suspected cause:** Shiny exterior trim piece on the outside of the car.
- **Fix that worked:** Honda replaced the trim piece, **part 72470-T24-T01**. FiveSeven108 https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-1022439/
## 21. Engine-bay firewall rattle
- **Symptom:** Rattle from engine bay on rough roads.
- **Location:** Top-center firewall plastic brackets/clips.
- **Status:** Reported but unresolved as of Dec 2025. cryptolime https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-1015117/
## 22. AWE Touring exhaust rattle
- **Symptom:** Rattle at certain RPM/resonance with AWE Touring exhaust installed.
- **Two known causes:**
- Muffler too far back, rubbing rear heat shield. **Fix:** Move muffler forward; or trim/bend the heat shield away from the piping with a pry bar. UJX https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-885638/
- Broken internal weld inside the Touring muffler — warranty issue with AWE. UJX https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-885636/
## 23. HVAC whirring at low fan speeds (likely normal)
- **Symptom:** Whirring/whining from the HVAC, audible only at parked-low-fan setting; goes away at higher speeds.
- **Status:** Reported on both the FL5 (~2k mi onset) and the Integra Type S (~1,200 mi onset, post-warranty visit). Likely shared HVAC components and probably normal. No fix proposed in thread. FL5 report https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-857756/, ITS confirmation https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-857847/
## 24. Wastegate whistle (normal)
- **Symptom:** Whistle when letting off throttle in 3rd or 4th gear.
- **Status:** Normal — electronic wastegate, same noise as on the FK8. Aftermarket exhaust muffles it somewhat. elusiveaura https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-863430/

## Cross-cutting tips that came up repeatedly
- **Dealer service caveat:** Multiple owners (and one Honda service manager in the thread) warn that having the dealer pull the dash apart often introduces new rattles via broken clips and loosened panels. DIY foam/felt fixes tend to produce better outcomes for minor rattles.
- **303 Protectant trick:** TypeRD reports that some "rattles" are actually two tightly-fitted plastic pieces *rubbing* against each other (stick-slip), and a small amount of 303 Protectant sprayed into the seam (with surface excess wiped) damps the noise without dismantling anything. post https://www.civicxi.com/forum/threads/interior-noises-rattles-creaks-squeaks.51263/post-868792/
- **Diagnostic approach:** Drive with a passenger who can press on suspected panels while you drive. Many owners spent weeks chasing a symptom that turned out to be in a different location than where it sounded like.
- **First-wave FL5 risk:** Cars in roughly the first 600 VINs / first wave appear to have the worst rates of seat creaks (improper welds — recall) and other early-build issues. Later-wave cars (e.g. car #2880, #2888) report few problems.
- **Material consensus for DIY fixes:** Felt tape, Tesa tape, foam tape, "yoga mat" foam folded over, and Siless/Dynamat sound-deadening sheets are the recurring tools owners use successfully.
