Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Was driving on both highway & neighborhood streets and the air bag fault light & warning tone came on. After many diagnosis drive tests, I learned that every time making a complete left u-turn the airbag fault indicator would disappear. However once completing the full left u-turn, and driving straight center wheel position, the airbag fault indicator light and warning tones would reoccur. When contacting my onstar monitoring service, they were able to do an over the air diagnostic fault code test. …”

“The key fob contains the ignition key and unfolds with a button press, but the spring mechanism holding it open is a bit weak. When you have it attached to a key chain, the weight of the keys can fairly easily make the key fob fold over in an l shape with the key in the ignition. This happens while driving often, and being 6 ft 1 in tall, my knee bumped the keys while I was putting my foot back and forth between the gas pedal and on the brake. …”

“After putting the vehicle in park, the key will only turn halfway. This results in the key being stuck in the ignition. This occurs intermittently, but tends to get worse the more frequently the vehicle is driven. Only way I have been able to remove the key is to turn the vehicle back on and rotate thru the gears. Sometimes it takes 5 or 6 tries. Also the side view mirrors will not operate all the time either and according to the dealer, the mirror and the key ignition run thru the same wire harness in the shifter mechanism. I have taken the vehicle to the dealership 2 separate times. …”

“Rear passenger door and drivers door are not locking with remote key or electric power door switch. This began with only the passenger rear door but has migrated to drivers door as well. This problem could lead to theft of internal contents and worse, vehicle robbery.”
