I had the TSB done months ago (don't have the paper in front of me, so can't confirm the number) but it didn't change a thing. It literally over-corrected on the right turn to get out of the dealer's lot. I haven't been back to ask about it again, but I've been paying attention here to watch for a proper fix.

I'll just add though, completely anecdotally. I had a loaner Equinox EV RS recently for a few days. Not sure if it was a 24 or a 25. I might be completely wrong, or crazy, or both... but the turn signal on that car felt and sounded (I mean the stalk, not the "tick tock tick tock") quite different than what I'm used to on my own car. And it didn't over-correct a single time over three days. Made me think that yeah, they probably can get it to work right through software (i.e. tweak the minimum dwell time for the signal to activate), but there's also something about the hardware.

 

With my wife's 2024, the stalk felt loose and it overcorrected almost every time. They replaced the stalk and it's now much more stiff.

Her car is now like my 2025 where it'll overcorrect 'once in a while' vs almost every darn time.

Her car is going in the shop next week and I'll see what they say about her 2024 (if a fix is available or not).

 

I had this fixed on my ‘24. They reprogrammed BCM as per TSB.

 

My 2025 Equinox EV RS AWD, built 5/12/2025, has never exhibited the RH turn signal overcorrection issue. I have received no OTA updates since I purchased the vehicle in June. I have asked my (horrible) Chevy dealer's service department to perform any and all available programming updates, which they have refused to do twice now. I complained to my sales person, who was fantastic, about their uncooperative service advisor and she said she wished they would fire him as everyone has issues with him. Never in my 50 years of driving have I dealt with a worse service department.

I do have a different issue with my turn signal lever that I am wondering if anyone else has. When pushing it down to indicate a left turn. It pops right back to the center, off position well before even starting to turn the steering wheel back to the right after completing the turn. I am not just pushing it lightly, as you would to indicate a lane change with 3 flashes. The detent that holds it on until you turn the steering wheel back to the right after making the turn just doesn't hold it. I reproduced this for this same idiot service advisor and he said it is normal.

Does anyone else experience this on their Eq EV?

 

No, and that is not normal. Maybe you should escalate (politely) to the manager.

This.
