I auto started my truck. We jumped in and I put the key in to start and turned down the heater and pushed the rear defroster off and the passenger side rear window blows up like a shot gun blast. It shaders into a million pieces. Our 2 year old in a car seat right in front of it rear facing. If I was driving with the amount of noise it produced I could of crashed. I see there is a bandage recall but not for the hundred of thousand of the 2014/2020 for back windows just blow out.

Truck has lane departure sensor, sensors you are too close, backup sensors. Last December these quit working. They thought be cause I put a new windshield in so they changes the windshield, then changed the camera and it didn't help. For 6 months they have been telling me they are working with GM technical assistance. Last week GM tells dealer need to change windshield, camera and a sensor, still doesn't work and now neither do any of the other safety sensors. GM calls and says they are working with technical assistance.

Duramax ticking noise. Consistent tempo ticking noise coming from engine bay. Audible only when moving at low speeds due to increased vehicle/road noise at higher speeds. Not consistent with RPM or speed. No warning lights or symptoms at this time. Dealer says not common, but appears common on the internet. Cannot find source of noise. Truck has 18K miles.

The dash has cracked in 2 places, and this poses a safety risk of shrapnel should the airbags deploy. I understand this is a common problem with this and related models. GMC should replace the dash.
