Example complaints

“I was driving on the new york thruway and all of a sudden, my car shut off. I had to power steer, no power brakes, the fuel gauge read no fuel and the bells went off. I had to try to get to a safe place and restart my car. This has happened many more times. I can be going 25mph or 70mph; I can have the cruise on or off; I can have the heat or A/C on or off, it does not matter; in all cases, the engine shuts off when I am not expecting it.”

“As I was driving along the engine, power steering, and brakes failed. I had to restart the car and hopefully resume driving so the car coming behind me did not crash into me. This has happened numerous times since including times while on I-95, I-81, rural mountainous roads (which resulted in my car rolling backwards), and city traffic. I have taken it in numerous times to my mechanic and he has not come up with a reason as to why this is happening. I am given no warning by my car that this is about to happen. The warning bell chimes and the car fails at the same time. …”
