Hello all, I recently purchased a used 23MY GR Core. The car had 58xx miles on it. I currently have a lick over 6k. I have noticed after driving I can smell a strong clutch odor. I noticed this right away when I first got the car 2 days ago (Certified Toyota Pre-Owned, from a dealer). I have been driving very conservatively and it still puts off that pungent odor. I have read up on other forums and have seen people have experienced the smell but it had gone away around 3-5k miles. So what concerns me is that my car is well over that and I am still getting that smell, and that I have been reading that peoples clutches have actually been failing extremely prematurely. I have to go back to the dealer I purchased it from to give them their dealer tag back and finish some paperwork. I notified them of this issue and they said they will look at it, I am curious if anyone thinks I should push for the dealer to put a clutch in it since I haven't had the car for a week yet. I even mentioned to the salesman after the test drive I could smell it, didn't think much of it (it could have been me since it was my first time driving the car, but I have years of manual experience (cars,trucks) and I came from a 21 corolla 6mt so I am pretty confident in my ability to drive manual). So if anyone has any ideas of what my first steps could/should be in approaching this issue I would appreciate it very much, Or if anyone is having a similar issue.

Also, the car automatically gives it gas when you are letting go of the clutch pedal. That's probably why you have to give it a lot less than normal compared to older cars that don't have that extra rev without your foot.

It only gives it more open throttle if it senses you're about to kill it. And, it "learns" - if you're consistently not giving it enough throttle, it consistently compensates. But if you're feathering the throttle appropriately most of the time, it doesn't play watch-dog nearly as aggressively. I've played with mine to watch this at work. I've killed mine a couple of times because it thought I had it all figured out and it didn't intervene quickly enough. Where you'll really see the throttle intervention at work is with a short-shift (very low speed) into 2nd gear.
I long for the days of a throttle cable - yet another version of me telling the car what to do rather than the other way around.

Maybe I'm in the minority, but I would love to be able to turn off anti-stall and hill start assist. It seems to mess with my inputs from a stop.

This isn't true. You can see the RPMs climb up before you even get to engagement point. This is the same thing across 4 of the GRC's I've driven owned by 3 different owners/driving styles. Even the GR Yaris I drove in Japan with 100k miles does the same exact thing.
I'm not talking about the rev hold in between gears. I'm talking about the pre-rev when you're at a dead stop going into 1st gear or reverse only. It doesn't do it in any other gear. As soon as you're in 1st/rev, and you start letting off your clutch pedal, it's at 1100rpm instead of 1000rpm. If you step back down fully, it's back to 1000rpm.

Not noticing that on mine.....
Until some YouTuber in the future does a comparison video between clutch assemblies removed from MY23, MY24(post 03/24 build date) and MY25 post face-lift GRCs, it is all speculation.

Confirmed with my drive this morning - my electronic throttle definitely will not intervene and keep me from stalling it taking off in first. If you're not on with your throttle foot, you can easily kill it and the e-throttle isn't trying to help. Maybe a difference between '23's and '24's? I just know that I have no rev hang, no help starting off or at low speed. And if I neutral it while coasting it quickly drops right back to 1000 rpm idle speed.
I drive my '24 GRC the same way I drove my 3 previous manual transmission cars that don't have anti-stall feature. But my GRC's anti-stall will still activate if you release the clutch without stepping on the throttle. I have doubts the ECU can learn and turn off anti-stall. Best way to test is to disconnect the battery, reset the ECU and see if your anti-stall reactivates.
If I put my GRC in first at a stop and let the clutch out without touching the gas pedal, the RPMs jump to about ~1400 just before the clutch engagement point. I never noticed this before intentionally trying it the other day, because I always give it gas, but it's definitely real.
I'm not going to try it myself, but I assume this will not prevent the car from lugging badly or stalling, unless you let the clutch out very slowly. I think it's probably meant as less of an "anti-stall" and more of an "anti-lug", bumping the revs to where the engine makes a bit more power just in case you mistime your initial application of throttle.

I tried the same thing - mine quickly dropped to 6-700 rpm and would’ve died if I hadn’t given it gas. My previous daily ‘17 Mazda3 would definitely open the throttle for you under those conditions.
Weird. I wonder if any other MY23 owners can weigh in.

If you feather the clutch long enough, it will get you rolling in 1st under its own throttle input.
This feature comes in handy for me when reversing. I just feather the clutch and the car applies enough throttle to back into parking spots etc.
This is how I teach people to drive stick (not in my GRC, though...).

Every manual I have owned has been 25 years or older, so I am used to an analog/mechanical experience. I can say for a fact there is definitely computer logic that assists with starts. And no, it will not stop you from stalling, but it makes it harder to stall.
These nannies feel very strange to me. The best way I can describe it is as if my inputs (or lack of inputs) are momentarily being ignored. I don't think the car is hard to drive, and at this point I've gotten used to it. But for me, a person used to no assists, it definitely feels uncanny. I feel similarly about the hill start assist.
All this in the grand scheme of things are very minor gripes and don't change how I feel about the car overall. I mitigate it to some extent by driving in sport mode to get a little more sensitive of a throttle response. I'm pretty sure disabling traction control will also turn these off, but realistically on the street I'd prefer to keep it on for those moments where you get caught out. I only turn it off on track.

Mine is also a 2024. I can literally rev the engine using the clutch pedal. I'll take a video later. The 3 other cars I've driven are
1) the very first car registered in north america (Nov 2022)
2) mid-year 2023
3) late-year 2023
My 2024 is an early 2024 (August 2023 build date), so maybe your late 2024 might have less of the rev?
If it makes a difference, I'm in the most normal basic mode. No buttons pressed/turned off. Maybe if you're in sport mode/traction off it doesn't do the rev.

Mine's in Eco mode - just checked again this morning while backing it out of the garage and heading down the driveway - reverse or first ---- no assistance from ECU/throttle at all -- if I don't "drive" it, it'll stall. Which is what I prefer anyway.

I'm perplexed. I mean yours would be the only GRC reported that doesn't behave this way. These features are pretty subtle, so it's possible you might be driving right through them. The rev hang isn't really a hang per se, it doesn't hold at a constant rpm, it's just the drop is slowed a bit. And the anti-stall is just a nudge at best, its nowhere robust enough to drive the car normally and prevent a stall all by itself. Think gentle clutch work, like creeping along in very slow bumper-to-bumper traffic.

As mentioned in one of the replies, the daily I just sold assisted with the throttle - I'm very used to this as a "feature", although I personally view it as more of a bug. Not my first rodeo - even this one would 'help you out' a bit if it felt you needed it. LS3-Powered 1982 Volvo 242 DL 5-Speed
I assure you, my GR has yet to apply the throttle without me requesting it via right foot. And I'm happy about that.
