“I was at a friends for several hours proceeding incident. I drove my 1999 chevy Monte Carlo z34 about 1 mile from my friends to taco bell. The car had been running great. I went inside to order I was in their 10-15 minutes. When I came out smoke was coming from under the hood. I opened the hood and the top of the engine was on fire. Taco bell employees called 911 and then provided a fire extinguisher. The fire was put out by the extinguisher and they cancelled the 911 call. I called a tow company and had the car towed home due to the hour and my engine being melted.”

I had a second opinion formed by 2 other mechanics who have both seen the same problem in the same engine (3.1l) w/this car - shouldn't chevy do something?”

“The contact owns a 1999 Chevrolet Monte Carlo. After refueling the vehicle, the contact noticed fuel leaking underneath the vehicle. In addition, the front driver and passenger side power windows and the air conditioner failed to function. The vehicle was taken to an independent mechanic who diagnosed that the fuel tank needed to be replaced and the air conditioning unit needed to be recharged. The vehicle was repaired; however, the failure with the air conditioner recurred. The manufacturer was not notified of the failure. The failure mileage was 80,000.”
