Tl* the contact owns a 1995 Cadillac Deville. While driving approximately 55 MPH, a large amound of smoke appeared from the front driver side. The contact pulled the vehicle over, opened the hood, and noticed flames. The contact extinguished the fire and the vehicle was towed to the residence.

The failure mileage was approximately 124,000.
I went to start my car (1995 Cadillac concourse) and before the engine turned-over, I heard a very loud pop, similar to a back fire, except that this noise came from underneath the hood. I then, simultaneously, noticed smoke coming from under neath the closed hood. I jumped out of the car and opened the hood to find that the engine was on fire. I ran back inside the house to get water and wet towels to try and put out the fire, which, after about 5 to 6 minutes, I was able to extinguish the fire. The engine had never caught on fire before this incident. Damaged to the engine from the fire appeared to be substantial in terms of wires, hoses, various plastic covers associated with the engine. Because I am not a mechanic, I can't say what kind of structural damage occurred during the fire. As a result of this fire, I have been without my vehicle since 5/7/09. …
The fuel line made of heavy plastic cracked and caused all the fuel to leak from the car near the engine as I was driving near my home. I am lucky the car did not catch fire before I realized it was leaking as I drove down the road.
Wife starts driving home and engine stops running, pulls off of road ,car won't start,she calls her husband and thinks the car is out of gas. He puts 2 gls in and car won't start, adds another 2gls,car won't start, calls tow truck, truck lifts front of car and there is a large spot of gas on the ground, thinking there is a hole in the tank ,car is towed to garage, new tank is ordered, 4days later we find the problem is the wiring harness burned and melted, outside of fuel pump burned and melted,top part of fuel tank burned and melted, this is a very serious hazard and warrants an investigation,contacted general motors and they ignore the problem. Thank you james b. Harakal.
I own a 95 Cadillac that had less than 3000 miles on it when I got it in 95. In 2000 the fuel pump shorted out in the fuel tank burning up the fuel pump and the wiring harness going to it. I had the car repaired at stutzman Cadillac in winchester va. In November 2005 the same thing happened again. I called Cadillac main office and talked to told them about what had happened. The only reply I got from them was they were sorry that I was having problems with the car. The first time this happened the car had 43000 miles on it . It now has 81000. It seems to me that there ought to be a fuse or something to keep this from happening.
I observed a liquid puddle about midway between the front and rear doors, on the driver side of the car. Upon further examination I concluded the liquid was gasoline. I felt where I thought the leak was coming from and felt tubing. I felt the a tube line and it crumbled in my hand. Upon further visual inspection, I observed other areas (along the drivers door) that were also leaking gasoline. Much of the gas line is crumbling plastic, causing gasoline to leak under the car.
