“My 2010 chevy HHR is leaking gas at a fast pace from the fuel line near the rear wheel. I smelled a strong gas odor and after parking I noticed puddle and dripping new my rear wheel. It was gas. I took it to a service shop and they confirmed that the fuel line was worn and broken.”
NHTSA complaint #11349150, filed 2020-08, 153,800 miles“A faint noise was heard and I pulled the vehicle over to the side of road walked around the entire vehicle looking to see if anything stood out, assessed the tires, engine and nothing appeared to be wrong. I proceeded to get on the ramp on and as I went through the toll booth driving around 40 MPH, the car accelerated to a speed of about 87 MPH, the steering could not be controlled it was almost as if it was in a locked position. Once the vehicle took off at the high speed, it then came almost to a complete stop. The sound of the engine was revving but the speed was not supporting the sound. …”
NHTSA complaint #11075777, filed 2018-03, 73,158 miles“While driving over independence pass in colorado at 14,000 feet, about a half mile from the top on a windy, two lane road with lots of cars traveling in both directions the car began to stall and stumble. We had to pull over the best we could not to block traffic (this is a two lane no shoulder, no guardrail, mountain highway with many switchbacks) we were headed uphill and with no power had to roll slowly back to the switchback to turn around. The car would start and stumble just enough to maneuver it around going down hill. …”
NHTSA complaint #10659124, filed 2014-11, 65,250 miles“In a parking garage on the 4th floor. Backing out of space. While backing up, I hear a loud boom. Nothing behind me. Thought perhaps a tire failure. Put vehicle in drive to pull forward out of traffic lane, and the engine accelerated uncontrollably. Brakes wouldn't respond. By the grace of g-d or reflexes, I turned the wheel to the right to avoid flying through the guardrail and off the 4th story of the parking garage. Vehicle came to a halt when it smashed into a concrete support pillar. Both air bags detonated, passenger-side air bag apparently broke the windshield on that side. …”
NHTSA complaint #10825181, filed 2016-02, 41,600 miles“After driving several hours, came to a road construction area and stopped for a couple of minutes and the engine began to stumble and eventually died after a minute or so. After setting still with the engine and ignition off, the car started back up and went on down the road without any further incident.”
