"Customer Care's" terrible response has me looking into initiating California's Lemon Law options. I can't believe the response I got from the people who work in Chevy's "Customer Care".

My neighbor has a 2024. He needed a valve body when the car had 900 miles on it. He said it was acting up again the other day. His car has 9,000 miles on it now.

Stay away from the 2024’s

My 2024 Lexus ES350 F Sport is currently in their shop for the third time for an electronic issue. My Nav screen goes blank when I’m driving it and I’m missing several different electronic features that I use. The last time I picked it up they couldn’t replicate it but it did it on my way home and again the next time I drove it. They “think” they have a fix now and it’s been there two weeks.

Contact a lemon law attorney as 30 days will come up quickly. I believe it won't cost you a dime should they prevail on your behalf.

Covered under warranty is not good enough for me, I don't want the inconvenience of having to deal with all the related BS. Otherwise I may be an owner.

My assumption too. Doesn't have a C8, roots around in the threads tossing out misinformation and BS guess's. Says dealing with a warranty issue is too difficult. Sounds like he should be driving a prius to me.

Hope everything goes well.
This sounds like the hill rollback control. Are you noticing this when the car would potentially roll backwards if shifted into neutral? If that’s the case, it’s entirely normal since the car holds the brakes until the clutch is partially engaged, causing a bit of a lurch forward.

The problem is, I’m not on a hill this happens on flat streets in stop‑and‑go heavy traffic. This is the only time it occurs, which is weird. I have to drive it in M mode to get rid of that whiplash effect.

This nonsense is still going on?

34k miles with 4 transmission replacements losing 5 weeks a years each year… usually just at or just after the 7500 transmission filter change.

its relatively rare and I’d probably guess less than 1 percent of the vehicles have it.

i believe for the most part it’s the parameter of the electromagnetic parking gear mechanism that causes the no stop, no start issue and the computer takes a crap.

ended up putting an extended GM warranty until 2030 and 93k miles and selling the vehicle.

picked up a beautiful 427 convertible with a short throw MGW shifter.

In stop and go traffic situations, there will always be a certain amount of "lurch" when applying the gas due to the first gear clutch engaging (it's not a torque converter automatic). Granted it shouldn't be neck snapping though.

Where is that guy from "Customer Care" who always chimes in on the forums telling owners to take their problem car to the nearest super Chevy dealer?

Default Excessive heat

Same issue. I drove my car two miles to the store. When I got back in strange whirring noise at start up then excessive transmission temp light came on. Purchased new 2022 Z51 has less than 12000 miles, all services done. Waited 5 minutes and car could now shift, CEL light on. Any ideas?

"Customer Care" called me to make nice and said they contacted the dealer and was told they know nothing about my car!
I gave her the name of my Sales Agent (aka Service Agent) and she said she will look into it. I am not holding my breath.
Tomorrow is 3 weeks it's been in the shop. It's like I am watching the movie Dumb and Dumber and I am a passenger on Airplane.

Not totally true, my early built 2024 has 10,300 miles on it no issues.

I’m sure the number of problems are relatively small or there would be a class action suit. But if it’s your car it’s a major issue. No one can rebuild these yet, we like disposable everything, who knows when they will try. But image having a 10 15 yo car when the c9 rolls out. There’s a lot of risk with a very complicated transmission. Ship has sailed but it would be so more comforting having a manual!


good luck op!

Monday 8/18/25 will be 4 weeks my Vette is in the shop to fix the transmission. I learned the problem was the transmission control module. The good news is they have gotten the parts from GM. The bad news is it's likely to take another week to finish it.
Culprits & Incompetence
(1) Chevy Dealers have very few parts on site.
(2) Chevy Dealers do not have enough help...only one guy at my local shop to do tranny work.
(3) GM is incredibly slow at approving warranty work for known problems. WHY? Do they think this helps their image?
(4) GM knew about transmission problems soon after the C8 was launched...still a problem for the 2024 year!
(5) Customer Service is a gross misnomer wrapped in incompetence. They called me to make nice after they told me I had a problem with
the (5 weeks) timeline for repairs. During this call they said my car was not at the only dealership in town! Wrong again.
(6) GM's latest software "upgrade" for the radio causes it to shut down and not play Sirius XM. They have another upgrade they will install.
Oh joy...if I had a physician this bad I would be filing a malpractice suit.
