NHTSA complaint #11206927, filed 2019-05, 150,733 miles“While running vehicle ignition switch went off and car was left without power steering and no motor power. I have to make a complete stop in order to start the car again. It all happens after getting my car to gmc campaign 14299.”
NHTSA complaint #10731903, filed 2015-07, 188,700 miles“I smell something like burning wires. The transmission light is on. Automatic shifting jerks. I am afraid of being stranded somewhere. I am 70 years old and need my car to be reliable.”
NHTSA complaint #11048441, filed 2017-11, 83,371 miles“This has happened multiple times, when driving at night, the headlamps will go off. There are other times that during the day, the message center display, radio and HVAC displays will go extremely dim. Is this a fault with the daylight sensor? Regardless, I do not appreciate having a car go down the road where the headlamps go out. I couldn't see. I was able to turn on the high beams and could see again. Next time I started the car, everything was fine. I am entering this information for my mother.”
NHTSA complaint #10654525, filed 2014-11, 70,000 miles“My wife and I were driving our new (to us) 2005 Buick Lacrosse with the rear window defroster on in sanford, nc. It was on for approximately 10 minutes. The rear window exploded into the vehicle while we were driving with what appeared to be an 8 inch hole in the middle. We bought the car approximately 3 weeks ago used with a 30 day warranty from steve jones honda in aberdeen nc. We haven't even made the first payment and we still have a temporary tag on the vehicle. …”
