Example complaints

“Vehicle engine stalls while driving. The car shuts off without warning. This is dangerous and not safe! I shut off while driving on the highway and when I was able to get it off the highway, it stopped in the city. Replaced the electrical body per the diagnosis and still experiencing this issue”
NHTSA complaint #11097268, filed 2018-05, 130,000 miles“My car has shut down while idling at a stop sign or red light. The first time was in 2006, but has happened several times since then. I've taken it to the dealership, but they said that they couldn't see anything wrong with my vehicle. I believe that my fuel gauge is inaccurate. It showed empty, and, then 1/4 tank. The rear wiper sweeps without being turned on.”
NHTSA complaint #10608262, filed 2014-07, 8,000 miles“Since the purchase my tb engine will stop when AC and heater is on on stop light, that it was delaying while driving. It got worse after warranty was out, I believe in july 2007.no one can find the cause, but thinking its all system faulty., engine, electronics, fans. Could I afford a new car, I would not keep this car, as now I know it was the worse year making of all. Now I only pray to stay alive while driving and not get into some beyond my control but faulty GM model makers”
NHTSA complaint #11062893, filed 2018-01, 70,000 miles“We were driving at about 55 (we don't know exact speed as our control panel is not working) and the steering went out. It was hard pulling to the right and a few times we could not control it and went off the road. We had another incident like that when we were driving in the snow. When we purchased the car we had a fuel issue that covered under a recall.... Now our whole panel is out. We don't know the speed we are going, the oil light and engine light are always on. We take care of our car so we know its not low on anything.”
NHTSA complaint #10576118, filed 2014-04, 106,200 miles“Problems with my 2005 chevy Trailblazer started with a series of engine lights, misfiring and stalling at low speeds and upon acceleration. My thermostat has been replaced numerous amount of times . I do preventative maintenance to keep my car in good working condition. I'm a single parent I need my car. My entire dashboard stopped working after getting stuck on and off. The fuel gauge was last to go 3 days ago. I fill up my tank it still reads empty with the light. My tailgate door the latch locks up. I manually have to move to latch so it closes. …”
