2023 civic si overrev

[jfloresnunez22688]

Hello community,
I am at my wits end. I’m humbly looking for any guidance or advice. My civic has 42k miles on it. I’ve taken it for every service as soon as it marked it. One morning my fiancé was taking the car to run errands when she heard a clicking sound. Almost as if there was a hole in the exhaust. She let me know and the car performed normal with the sound going away as the car warmed up. Couple hours went by when I recieved a call from her. She was frightened, when she started the car the noise returned only now it was more aggressive, it sounded like a fork stuck in a blender. She tried making her way back home slowly with her emergency lights, but she felt she wouldn’t make it. I went to help her out and see what was going on. She was literally around the corner from our house. As soon as I stepped in and tried getting the car to move it stalled on me and all the lights on the dash came on, prior to this there were no lights on. I towed the car to the dealership. They ran their diagnostic and it came back as an over rev. My fiancé and I have been driving stick shift since our driving career started. We over reved maybe once or twice going from 3 to 2 but I know that’s not enough to make the whole engine and transmission to give out. They’re now trying to charge me over $18k as an over rev voids the warranty. The car’s been sitting at the dealer for almost 3 weeks now. I owe about $26k left on it. Help I’m not sure what to do.

The ECU will count the number of times you have done this and how bad (RPM) for this reason specifically. You admitted to over revving it which will do damage that sometimes takes time to materialize.

A 3-2 shift near redline would definitely be a reason to void your warranty. I'm not sure why the transmission needs to be replaced. You might be able to get by with just buying a used long block but it won't be cheap.

TIme to start considering a long block?

Oh man, how easy is it to mechanically over rev on downshifts? I think I've come pretty close once or twice, but the car only beeped at me on a downshift once when I was rev matching it myself. My understanding is there's enough built in precautions that it actually takes a really bad downshift to damage internals (and trigger the code).

Super easy. If you redline 3rd gear and slam it into 2nd gear your engine is gone. This is what most people call the money shift. This is why it's so important to learn the proper technique for shifting. If you're shifting gears using the same hand position for each gear it's only a matter of time before you do it yourself.

Point noted! I have yet to slam gears on downshifts since I'm not even good at upshifting fast, but I'll make a habit to have different hand positions on every gear. Right now i have one for reverse, first, second, third and 4th, but not really anything particular for down shifting

 

[CTR]

There are probably hundreds of videos online showing to how properly upshift each gear to eliminate the potential for a money shift.

It shouldn't be common to do it on an intentional downshift. Just leave it in the higher gear if you're that close to cause the shift lights to come on. If slowing to a stop just put it in neutral until you have a feel for where you should be in each gear.

Your description sounds exactly like what happens when your pressure plate fails due to over revving. Tell the dealership to replace the clutch disc, pressure plate and pilot bearing and then go from there. I would bet a LOT of money that the only thing that has happened to your Si with a manual transmission is that your pressure plate has failed. I would bet even more money that the engine is not siezed up and the gearbox is just fine.
The dealership is trying to screw you badly, GUARANTEED!! Pressure plate, clutch friction disc and pilot bearing and drive home.

I don’t have the expertise to say @PNEUMA is right or wrong, but I can say adding an alignment and brake fluid flush to an already huge bill gave me pause. I would suggest a different dealer or shop Just based n the fact it seems they are adding on “needed” items. Your dealer should focus on fixing your issue only when it’s something this big.

The way they pulled up the over rev, it's like they knew that this would be a payday. OP should ask for the over rev time-stamp, some dealers could easily just over rev once before selling to protect themselves from being responsible for warranty work

Let’s step back and analyze this scenario.
OP admits that he and his girl know how to drive a manual gearbox. He takes care of his car and when maintenance services are due, he has them performed.
Also admits that in the lifetime of their ownership, they have overrevved once or twice. All of us know this is a Honda and any of these instances alone do not blow up an engine and gearbox simultaneously. Can it happen? Perhaps. Did it happen? Very very unlikely.
Towed to dealership (all dealership departments exist for one reason: to make money. As much as possible).
By the report posted, service dept mechanic states there was no leaks and fluids were at proper levels.
OP and his girl describe the noises leading up to this failure and a ticking (diaphragm pressure plate finger working its way out of it position) then a bit later/next drive the sound is like a fork in a blender (finger on the diaphragm PP is now dislodged and striking inside of gearbox housing). Nursing it home, car stops/wont start and drivetrain is locked up. Pressure plate has exploded at this point.
Dealership says an engine, gearbox and clutch assembly is needed to rectify the situation caused by an overrev. Bullshit! We know that an engine siezing up does not mean that a gearbox seizes up simultaneously. Could it? Maybe (but 99.9999 unlikely). Space junk could fall to Earth and kill one of us here, but unlikely.
Service department presents OP with an astronomical repair bill.

Let’s say OP is savvy and would like to see proof that his engine/gb is siezed?? More than likely they would take him to his car and show him it won’t turn over so that he can ‘trust’ their diagnosis (really it won’t turn over/roll due to the grenaded clutch assembly).

What would the dealership have to gain by misleading the OP? $$$$. They try to sell him a new car, and offer to take his badly broken Si in trade at a low value. More than likely convincing him that it’s undesirable with the amount of damage it has (supposedly). They make money on the new car sale, then replace the clutch assembly ( maybe even flywheel), then put the Si out on the lot for sale and reap an even higher profit than the new car sale netted.

I still stand by by internet diagnosis of this being a grenaded clutch assembly. All of the signs are there. If you read this OP, get your car towed to a different shop (even an independent) since the warranty may be expired due to 42k miles. Don’t know if you purchased an extended Honda warranty.

Please let us know how this shakes out and best of luck in an inexpensive resolution

...since the warranty may be expired due to 42k miles...

I thought the powertrain warranty was 5-years/60k miles?

 

[PNEUMA]

I thought the powertrain warranty was 5-years/60k miles?

I could be incorrect. I have a CTR and Accord Touring. Both have 3yr/36k, whichever comes first, for the warranty period.
And again, my whole hypothesis with the OPs Si is purely that, an educated guess.
Sure hope he gets a second opinion/diagnosis of his cars condition.

Thank you I really appreciate you reaching out. I knew something fishy was going on from the start. Im going to the dealer today to ask them for proof of the over rev and time stamps, possible rev limiter malfunction, even the issue Honda has been having with their 1.5L turbo engines and their fuel dilution. Im requesting a denial of warranty if they don’t do anything about it tans take it to get a second opinion. Depending on what comes from the second shop Im lawyering up. This has been such a headache, I appreciate everybody’s input in my situation

I truly wish you the best in this situation. Hope they can prove to you without any doubt in your mind the condition of your engine and gearbox. If they refuse to show you and/or start backpedaling, you will know that you shouldn’t ever patronize this dealership ever again. No matter, a second opinion is necessary. If possible, make your visit to the dealer a surprise.
