I was never informed of this recall! I just happened to check due to a seperate issue that's been happening(the transmission seems to be slipping, which I also read 2015 traverse's have that recall too, just not under my VIN) But it upsets me that I never received notice on this and the recall was in May 2023 and it's now March 2025!! I drive this car DAILY and also have my boyfriend in the passenger seat DAILY on our commute to and from work!!

The 2015 Chevy Traverse had a hard shifting transmission from the first day we purchased it. The Chevy Dealer said that it was a shifting software problem. That did not fix it. The hard shifting transmission caused an engine motor mount to break twice. (There was a safety recall on the motor mount) That engine motor mount caused the power steering fluid to leak out. I contacted the Chevy Dealer and they said contact General Motors. General Motors ignored the problems.

While driving the traction control, stabilitrac, all wheel drive, and abs systems will turn off and says to survive them. We have had the vehicle in to 3 different mechanic shops and the issue still persists. Each time a different "fix". This time the wheel speed sensor in the rear was replaced. We have had the other rear wheel speed senor replaced previously as well as the rear wheel bearing hub assembly.

VEHICLE BEGAN STUTTERING WHEN UPSHIFT OR DOWNSHIFT 2ND-3RD GEARS LOW SPEEDS. TOOK TO DEALER. AT FIRST COULD NOT REPLICATE BUT THEN FOUND GM SERVICE BULLETIN # 18-NA-358 (SEE ATTACHED). FIRST RELEASED IN NOVEMBER 2018 AND MOST RECENTLY UPDATED OCTOBER 2020. IT LISTS THIS EXACT PROBLEM AND A FIX FOR THE PROBLEM. IT INCLUDES MANY GM VEHICLES INCLUDING MY 2015 CHEVROLET TRAVERSE. THE DEALER SAID THERE WAS NOT A RECALL THAT THIS WAS JUST A NORMAL BULLETIN TO HELP TECHNICIANS HANDLE PREVIOUSLY REPORTED PROBLEMS. I WOULD REQUEST SOMEONE TO REVIEW FOR A POSSIBLE RECALL. MY TRAVERSE ONLY HAS 94,000 MILES.
