GM pushed a system update to my truck last week. I noticed the front bumper sensors are no longer working. In addition, the auto start-stop function no longer works.

I was pushing the accelerator, and the transmission hesitated at about 45 mph. For about 2-3 seconds, the vehicle would not upshift. The RPMs revved, and finally the vehicle slam-shifted into gear. The vehicle drove normally for the rest of the drive cycle.

The contact owns a 2026 GMC Canyon. The contact stated that while driving on several occasions and exceeding 35 MPH, the contact noticed an abnormal sound coming from the steering column. The vehicle was taken to a dealer, where it was diagnosed that an unknown steering wheel part was damaged and needed to be replaced. The vehicle was not repaired and was taken back to the residence. Additionally, the contact stated that while driving and exceeding 45 MPH, the vehicle shuddered on bumpy roads. The vehicle was taken to the same dealer, where it was diagnosed, and the dealer determined that an unknown part needed to be replaced. The vehicle was not repaired as of yet because the part was not yet available. The manufacturer was notified of the failure. The failure mileage was approximately 600.

With 94 Miles my brand new GMC Canyon AT4 I leased had a catastrophic failure while i was driving it, the front axle essentially exploded. The findings were that their was no oil/lubricant installed in it from the factory which made this happen. I now have to wait many months for the dealership to repair my vehicle while i have a "loaner" with a bunch of restrictions on it. And i have to pay my lease the entire time it is being worked on because of a factory fault. If i had been going more than 25 mph this would have resulted in a crash/injury.

when apply GM update V661.10. tire pressure sensors are wipe out. resulting in 4 flat tire being indicated on the display. GM has no answers for this. this is a safety system that should not be disabled
