Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Failure of underbody/frame rust undercoating. The undercoating has completely flaked off the frame of my truck with 90k miles. I am the only owner of this vehicle which has been garaged since day one. The vehicle is also rusting thru from the underside of the hood. I have contacted Gmc about this issue both in person & on the phone. They have denied any liability in this matter.”
NHTSA complaint #10959038, filed 2017-03, 85,000 miles“Dashboard is cracked in multiple places. One crack is along the passenger airbag and the second is along the drivers side in front of the instrument gluster. The first crack appeared as I was leaving my driveway and the other was while driving down the street. I am worried that the airbag crack could cause sharp pieces of the dash to project in the case of a deployment of the airbag.”
NHTSA complaint #10956660, filed 2017-02, 110,000 miles“I have a large section of my dash pad broken on the drivers side. I also have a crack on the passenger side. This was not caused from abuse but from inferior materials. It appeared sometime in 2015 with about 130,000 miles on it. I have owned it since new. …”
NHTSA complaint #10947054, filed 2017-01, 80,000 miles“My dashboard has several cracks exposing the electrical components within the dash. These cracks are in various places across the entire dash. I purchased this vehicle brand new and it is currently in excellent condition (with the exception of the dash) I am concerned that if the air bag were to be deployed the plastic dashboard would explode and expose my passengers or myself to additional hazards within the vehicle. I am also concerned that the electrical system in my dash board is now exposed to additional hazards due to the additional exposure to the sun. …”
NHTSA complaint #10903689, filed 2016-09, 131,879 miles“Vehicle's airbags did not deploy upon collision with two concrete walls, causing a life threatening tbi and also severe damage to the left arm which resulted in it's inability to control/use below the elbow, and especially the hand. This was due to the brachial plexus injury that was caused when the airbags did not deploy as they were supposed to. I have attached the report from police and insurance company (with photos).”
