“Plastic fuel tank is leaking. Tank is manufactured with two cone shaped depressions in the bottom of the tank. Straps hold the tank in place. These straps almost cover these depressions, the tank leaks at the depression on the right hand side allowing fuel to escape. Contacted GM, file number 1-109-911-920, but was told that GM would not cover the cost to replace at this time since insufficient complaints had been received to date.”

“Tuesday morning, august 17, 1999, I stopped and put $10.00 worth of gasoline in this vehicle, and drove to work. At lunch, I drove the vehicle to lunch, parked in the parking lot on a slight incline, and went to lunch. Upon returning, we found a small group of anxious people looking at my car from a short distance. Gasoline was leaking out from under it, and had run about 15' down the pavement, forming a puddle. The fire department had been called, and was on their way. We manually pushed the car away from that spot, onto level ground, and the dripping fuel stopped. …”
