On a rainy night, Jan 10, 2014, I came out of work and started my car. I thanked god it started because sometimes it wouldn't start at all. Even after replacing almost every engine part including the computer. I started driving out of the parking spot and I smelled something burning inside the car. The engine started revving wildly up and down. I had no control of the car. White thick smoke filled the car fast. Flames started shooting out at me from under the dashboard. I was so panicked that I could hardly get out of the car. The insurance co totaled it and I still owe 500.00! I've spent more money trying to get the car to start when I want it to and to stop shutting off while im driving on the highway with my children and or infant granddaughter. This 2003 Saturn L300 has been nothing but a financial and mental nightmare only to go up in smoke, ruin my credit, and leave me stranded with no vehicle once again.

The contact owns a 2003 Saturn L300. The contact stated that the vehicle would exhibit a sharp and abnormal increase in engine rpms when attempting to accelerate. In addition, the vehicle would also exhibit an unusually loud roaring but would not respond. As a result, the catalytic converter failed. The dealer advised the contact that they are aware of the failure but they could offer no assistance. The vehicle was not repaired. The failure and current mileage was approximately 133,000. The consumer stated the interior and exterior lights flicker along with the heater, which seems to come intermittently. The water pump and timing belt were replaced. Also, the catalytic converter motor and battery were replaced. Updated 04/15/11
