What owners wrote
A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
Dt: the contact's vehicle was involved in a crash. Upon impact neither of the front air bags deployed. The vehicle was pulling a trailer when the trailer hit a spot of ice. Then the vehicle went out of control and rolled over. A police report was taken at the scene. Both the driver and passenger sustained injuries. The manufacturer has not been contacted.

Was driving home on the highway and swerved hitting the divider with the front left corner of vehicle. The seatbelts did not hold me in my seat and my head shattered through the window striking the street light lamp. Airbags also did not deploy meanwhile I was on the highway going about 57MPH. The injuries were drastic including partial amputation of my ear, I was in a coma for a few week, 3 skull fractures, tbi, brain bleeding and the list of injuries continue to grow!
Went to start my vehicle and it flashed service airbag. Took it to the GM dealer and they say its the left front impact sensor. I have heard that this is a common issue for these vehicles and think that this being a safety issue, should be covered by the manufacturer.
Truck cut off while driving saying reduced engine speed and service stability and now truck will not crank with key in ignition everything goes backwards on dash and goes blank also when adjusting steering column service stability light comes on and off is when lost power to truck.
