While sitting in front of my home my 1999 cadillac deville caught on fire and burnt to a total loss. The car was parked, had not been driven for about 48 hours. The fire started in the engine compartment. The fire occurred at about 2:00pm. Satruday afternoon. Temp about 82 degrees. Something in the cars engine room on the left side ignited. It appears to have been an electrical problem that self ignited. Just prior to the fire, my wife who was at home at the time heard the car alarm go off. She went to the window and it quit sounding. She did not see any fire at that time. About 5 minutes later a neighbor pounded on the door and alerted her to the fact that the car was burning. The fire was so intense that before the fire department got to the seen, one of the hood gas struts blew through the front grill and landed about 20 feet in front of the vehicle. The fire department came and put out the fire. Something obviously within this cars engine compartment electrical/computer system started the fire. The car is a total loss.

First time engine failed while driving on interstate at approx 75 MPH. Engine completely shut down while passing semi. All lights on dash came on and total loss of power steering. After serious scrambling to get car off road and bring to safe stop attempt to restart was successful and trip of 600 miles continued w/o incident. Five days later same thing occurred on suburban street in heavy traffic at approx 45 MPH causing a lot of consternation by drivers behind me that did not understand why I came to sudden deceleration. Took car to cadillac dealer and they found no problem. They charged me $112.50 for engine driveability and performance diagnosis and did replace a defective egr valve which I feel had absolutely no assoc w/ stalling problem. I think after looking at all the other filings of this problem in the federal safety agency records, that cadillac has a real problem and had better get on it before someone gets killed. Dt
