When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

POWER TRAIN
I was driving and noticed a very strong smell of an electrical fire. The truck popped up a High Voltage Battery warning and several warning lights came on. We stopped, restarted the truck and the lights came on again, the smell returned as soon as we started driving. We drove the truck to Cable Dahmer GMC in Kansas City, MO. Service advisor Kracinda asked us to exit the vehicle as quickly as possible as it needed to be moved away from the building ASAP. It was parked several blocks from the building in a col de sac away from all vehicles. The electrical fire smell was very strong. The manufacturer is now saying that a software update is all that is required.

SERVICE BRAKES
After the latest update from the Dealer, the integrated trailer brake module no longer shows an output of how much power it's applying to the trailer brake system. It just stays blank. I can tell that the brakes actually are being applied, however not having indication of them being applied and how much pressure is applied is concerning.

While on freeway going 75 mph, GMC installed soft tonneau cover came loose from forward anchor points and starting flapping loudly in wind and without quickly stopping would have flown off truck and hit surrounding vehicles.

VISIBILITY/WIPER
The truck bed cover is not secure, it fits in via a channel with no straps or other protections and so when driving on the highway, it flies off from the connection to the cab and you can’t see behind you. It then smacks into the car until you can pull over. There is no protection against this.
