Some hatch owners across other socials and various Hatchback clubs have been learning of a potential issue with the clutch of the 12th Gen manual transmission Corolla Hatchbacks.
I learned about this through @JulioTRD and Hachiback through Instagram.

There is a distinct whirring sound that dies out whenever you clutch in while in neutral. This could be pointing to a potential issue with the input shaft of the manual transmissions.
I checked mine this morning after a cold start and it was very obvious. My Corolla is a 2019, XSE IMT (J Vin#) with 32k miles on it.

One dealership was heard to be quoting $2.8k and another almost $6k cost for a transmission tear down.
If the issue is indeed the input shaft, these could fall under warranty, and hopefully covered for you.
We are trying to gauge how widespread this issue is and figured we should bring it to your attention here.

Its been evident that the CVT's have been facing issues, but seems like even the IMT's are too.

Note: Currently I am unable to add soundclips, but hopefully can attach some within the next day or so.

Never fails to amaze me how automakers can manage to screw-up certain core-mechanics that should be basically perfected designs by now. It's like they try to re-invent the wheel over & over again with cheaper & cheaper materials & added complexity. I drove nothing but manuals from 1982-2022 & never had a single clutch/transmission/gearbox issue until my 2020 6-MT Corolla SE sedan. All the added tech-bloat, complexities & corner-cutting for added margin are making newer vehicles more of a time-bomb than ever.

What issues you are talking about?

 

[JulioTRD]

Thanks for making this bro. I've created a folder in my google drive that I will try to keep updated with videos people send in the corolla discord chats showing this issue on their cars. I've attached the link below so everyone can go in and hear the issue we are talking about. You'll have to listen closely.

Not a Corolla but also had the same issue before on my 2013 Scion TC(6speed) also a J-vin# . Dealer repaired and replaced the part twice under warranty but the same noise goes back after 5k miles. Did not bother to have it fixed for 3rd time and just lived with the noise til I sold it.

Only issues I know of were early batches of the 2019 hatchbacks had an issue but I don’t know if anything other than that.

I’m pretty sure that was the batch that had issues with the torque converters on the cvt

That was the recall I was referring to. Just looked up the details and on the early batches of the 2019 hatch referring to the impeller blades in the torque converter.

So it wasn’t even an issue in regards to the CVT system, but just a faulty torque converter.

These damn J Vin hatches are making the rest of us look bad.

I wonder if it'll transfer to the US made sedans with the 6mt I haven't heard any cases so far but the more hatches that keep popping up makes me skeptical.

I think I’ve seen one sedan with it. I’d double check just to be safe bro

Not surprisingly, given how new it is, I'm not experiencing any of the symptoms on my 2022 hatch. However, I'm thankful that people are documenting this. If this becomes an issue for my car down the road, it'll be good for there to be a track record I can point to.

The guy with the blue hatch in the linked Facebook post is local to me. He's getting rid of the car now because right after the dealership replaced his transmission due to the failing Inner Shaft Bearing, his slave cylinder went out. I thought maybe his car was just a lemon at first or maybe he just has bad luck but after seeing all of these failures, it may be a factory defect on the EG60 transmission. Although, I do recall reading about a redesigned slave cylinder on the EG60's since the early ones were failing?

Not a Corolla but also had the same issue before on my 2013 Scion TC(6speed) also a J-vin# . Dealer repaired and replaced the part twice under warranty but the same noise goes back after 5k miles. Did not bother to have it fixed for 3rd time and just lived with the noise til I sold it.

Early tC2's (2011-2013ish) had a factory defect with the inner shaft bearings on the 6 speed manual (EB60) transmissions that would cause it to fail. Could the new EG60 also have the same defect? Possibly but I also haven't found any sources showing that Toyota revised any parts in the transmission yet.

It's weird because the EC65 was a reliable transmission with no real issues. Even the C59 trans before it was mostly problem free (in the 10th Gen).

Hmmmm, guys, does anybody have an idea how wide spread this issue really is? Based on this discussion so far, I counted may be 5? I read this thread with great interest because I have a 2019 6MT HB. This car fits our needs and has been wonderful and problem free since new. We are retired couple and thinking this HB may even be the last car we would buy. A pricey MT repair down the road is not a good thing. I understand no car manufacturer can produce 100% perfect cars, good odds is all I can ask for. For over 3 years being somewhat active on this forum, I don’t recall seeing anybody complain about this issue. This seems strange to me, or is just my dementia kicking in? If the problem was reported only by a handful of people, then I would just go back to watch my TV.

That's because your US VIN beats up our J VIN.

 

[tmport]

I'm curious to hear from people who are technically minded what they think of this issue. From reading through posts in the Facebook group, it seems like this might be more of a nuisance (noise) than a threat. A number of people said you can live with this issue for many miles/years without the transmission failing. Is that true?

I did know a while back an apex user was on here commenting on possible clutch fork noise upon disengagement
.. but that was months ago and they haven't posted since

Lol I know I joke only because this transmission issue seems more one sided (for now anyway ) but in all other terms of J vs NA I do naturally assume the fit and finish of the overseas products would be of better quality / more attention to detail etc.

I may be misreading things, but it sounds like nobody’s trans has actually failed from this.

 

[Toddmon]

19 XSE 52k. I am experiencing the “whirring”, I have had first gear/reverse lock out issues ever since have owned the vehicle. Changed gear oil at 35k. I am extremely curious about the potential for failure stemming from this issue.

 

[JesseCorollaHB]

Not sure if the MT failure in my 2020 Hatchback is related to this, but mine completely failed at 46k miles. Dealer pointed towards the clutch release/throwout bearing as the culprit. I’m still not 100% sure what it was.
And yes I know how to drive a manual, I’ve owned many with no failures like this.

My advice to anyone with the MT, keep a close eye on the fluid level. And have your dealer document any issues you notice, even if they can’t “replicate” the issue.
