Clutch Slipping on stock A91 MT...

[trev_rs]

If anything rev matching should help preserve the clutch. It operates perfectly.

I agree, in theory, this should decrease wear for the less adept manual drivers at least.

I 100% think my problem is isolated and not even clutch related but more so slave cylinder or pressure plate, but yes what Phil said I agree with 100%, 99.99 of the time I have auto rev match on, it is quicker and smoother then I ever will be and It makes me sound like I know what I am doing, my distain for the car and comments about selling are partially hyperbole and exaggerated but also more so due to the fact that I was told they wont investigate my issue without paying a tear down fee of thousands of dollars, something I feel is ridiculous on a 3k mile stock car, especially since I first complained about this at 1k miles and that is on record, next they told me that if I do things on my own with disassembly and or install an aftermarket clutch to remedy the possible issue, my whole powertrain/drivetrain warranty will be subsequently voided, a catch 22 as I specifically bought an MT to enjoy and keep mechanically stock as I am entering law school soon as well other life changes where I no longer feel comfortable having the risk of a $10,000 bill if something serious fails, with my fbo 2020 I modified and tuned it knowing that risk was there and ready to "pay to play" but a majority of the reason I went to this 23 was to have a nice factory fresh warranty incase anything happened. Now my option are as follows : pay out of pocket and put an upgraded clutch in hopes it fixes my issue, one that I don't even think has to do with the clutch, and then void the warranty on my brand new car, Pay a tear down fee and "hope" that the FST finds an issue he deems as a parts defects, a very subjective and difficult process that risks thousands of dollars on my end, drive with the car until it eventually fully fails and hope it happens before 12k miles, and even then still risk them fighting me on the repair. It puts a very sour taste in my mouth as I feel like no matter what, I am getting screwed one way or another.

Yeah you have every right to be upset with the options they’ve given you. Also I don’t think they can just void your entire power train warranty for replacing a clutch. These dealerships love to just throw out crap like that. You definitely shouldn’t have to go that route anyway and I wouldn’t.

I’d escalate the situation with Toyota if you haven’t already. It’s a new car and they should at least investigate the issue on their own dime. If they can prove abuse caused it after a tear down, then they can talk about billing you for the repairs.

I am 2k into my MT....... no issue just my own faults with the accelerator and a blinking traction lights.

I have been reading that past 10 pages of "thoughts and opinions" My experience with BMW has greatly been on S1kRR (BMW motorcycle) at the racetrack. the traction control on the moto's is ridiculous, almost violent at times. Depending on the throttle setting (ie. rain, sport,race) the intervention of traction control varies from subtle to scary. The initial feeling is complete power failure and immediately back to plaid.

I am curios if the same interventions from traction control are simulating the sensation the clutch is "slipping". Is TCS off when this has occurred? The Supra responds differently when TCS is completely off. No interventions.

Anywho, Call me idiot. Thinking outside the box. ZF makes a strong product. and I believe Toyota has built a product around a "stock" platform.

Recommend hitting the safety button one click and turn that crap off. Totally agree with you. It’s extremely intrusively.

Phil nice photo there. Very nice. Is that you riding?

Yes, Phillip Island. Lucky Heights turn 9. On the Ducati this time.

Guys and gals let's take a second to regroup here. I mentioned this in GR's thread, but this is a great place for us to share information, but we have to base it on fact not opinion.

Data is what helps us build theories and answers. Everything else is just speculation. If we look at things like build date, country having issues, stock vs tuned, was the break in followed prowling and many other things that have empirical data values we can start to see a trend.

For instance, one thing that seems to have popped up is that @GRSupraPR had noticed many of the issues are with other cars in PR. The US cars that are having issues, beside @NitroYellowMKV, really are self inflicted and sometimes corrected.

I'm all about shit posting and having fun (that's what makes this community great), but if we're going to try and make a realistic determination as to where the platform has a serious problem, we need something tangible that can be used to build a case. Who knows, it could be the real world data needed to help Toyota put together a fix if it's needed. They could find that it's an issue with settings at the factory, etc. But NONE of that can really be determined if we don't have really information to back out up.

Sorry, I'll get off my soap box now.

I loved the platform and it was a great car to drive until a simple clutch malfunction and a poor service by the dealer and Toyota Puerto Rico changed my heart.

Now I own “Sports Car” parked in a dealer shop and a dealer asking me to pay for something that clearly should cover under warranty.

In my humble opinion!!!

That makes compete sense and I'm sure that no one would argue with why you feel that way. It's a loss than ideal situation to be in and we're all hoping that you get a good resolution out of it so you're able to enjoy your car again.

I have this on my auto insurance for my 2023 MT Supra. I wonder if this would cover this issue if I came across it or perhaps cover the dealers inspection fee.

 

[CortC]

2K+ miles and no issues, been driving a manual transmission sport cars, muscle cars, sedans, trucks, etc.; motorcycles included from just about every manufacturer since since the early 80s and never have had a problem with a clutch that was properly driven and not abused.

Toyota, BMW and ZF all had input into the design and implementation of this manual transmission and clutch assembly. I doubt very much that of all the things they could get wrong it is one of the oldest and most proven systems in a vehicle.

There is probably just two possible root causes for these issues:

1) Isolated manufacturing flaw or assembly error..
2) Driver error or abuse.

Assuming ur referring to Geico. They would want to approve the repair job first, and they may even request a claims examiner do their own inspection. Would strongly recommend holding onto that coverage.

You have the modern riding style, lower body position forward over the tank. My is old school from someone that grew up on dirt bikes. Plus I'm old as well. Compare. Me sitting more upright with the shoulder leading ready to catch it if it tries to high side me. The GSXR and the 1000ss don't have traction control but my 1198 does. I still ride it with the same style though.

Beautiful @Foogazzi and lucky Phil! Both of you guys need to come over to the booring side and track your Supras, if you aren’t already. The best drivers tracking their Porsches, Supras, Vettes, MX5s have either a carting or bike background, for sure! Y‘all will take to it like a bee on honey .

Most of the motorcross guys I’ve met broke so many bones they finally make the switch. Glad you both are still in one piece!

Never had more fun than on my 675r
Triumph made a perfect bike.

@Phil I was fortunate enough to work for a BMW, Triumph, Ducati dealership.

Above is turn 2 Jenning Gp in north florida

1198sp was always my favorite. Ruthless mid corner speed leaving tar snakes everywhere.

Favorite tracks: Roebling Road and Barber

I will be at Barber July 15th with “BLUPRA”

 

[FLtrackdays]

Question being, which one of you have broken the most bones? At the track we talk about broken car parts But y’all are on a completely other level! I remember one guy telling me he was worried about his bike during a fall, so he made sure he place himself between the pavement and where the bike was going down. He spoke about it like it was a natural thing. Not bragging. It was just a ”of course I put myself down to protect the bike” 🫠 @lucky phil @Foogazzi
