At slow speeds, mainly when backing and turning wheel when going forward at very slow speed, steering loses power. Also some times hard to turn when vehicle not in motion at all. The last time it happened all interior lights and radio flashed totally off and right back on. I heard a dinging/warning noise and a warning message flashed but went off before I had a chance to read it.

While parked and idling in a parking lot with passengers in vehicle, there was a sizzling sound followed by a flame flicker observed directly behind the driver's side, rear passenger seat at the bottom of the rear, driver's side glass panel. Shortly thereafter, the rear, driver's side glass panel shattered. My vehicle has rear sliding glass and only the driver's side panel shattered. Smoke and burning smell was noticeable. After online research, I discovered the GM recall #N192220470 related to 159,000 Canadian vehicles. My situation matched the description of this recall exactly, but according to GM, my VIN# is not included in the recall. My vehicle is currently at my local Chevy/GMC dealer for diagnosis and repair, but they don't seem to have much concern about the safety failure and told me the repair is not covered by warranty. To me, this is a serious design flaw and poses a potentially dangerous safety issue.

On numerous occasion the vehicles intierior audio chimes do no alert if doors are open, seatbelts are fastened, or blinkers are working. In 2014 the General Motors recall number 14315 addressed this issue but GM states my VIN number does not included the vehicles affected even though its exactly as they describe in the recall campaign in 2014. They want me to pay for the diagnostic and repair despite it being a safety issue and a recall they addressed in the past.

Touchscreen interface will randomly select and change settings anything from a radio station to passive lock safety settings. This will happen whenever there is a key in the ignition and the screen is active. Happens all the time and is repeatable. Touchscreen controls most settings for the vehicle.

On several occasions all sounds from door chime, radio, onstar, etc. Have failed. Further the paint is beginning to blister from underneath. GM is denying both problems exist. GM says the paint issue is due to application of an extreme heat source. Arizona is hot, but not that hot. The sound issue is a safety hazard. The paint issue is typical corporate denial of legitimate claims.

  • 60,000 miles
The bulbs in the tail lights corrode in place due to excess road grime (salt, sand, etc.) being splashed up on them. This causes them to burn out prematurely and removal is impossible due to the corrosion of the bulb into the socket. This results in having to replace the entire wiring harness. According to my local GMC dealership (West herr), this is a common problem that GM isn't covering. So, I had to pay for a new wiring harness out of pocket in order to replace one of the tail light bulbs.
