I started my car in the morning, per my usual routine. After a few seconds, I heard a very loud bang and the car stalled. A few seconds later, there was a large amount of smoke coming from under the hood. I opened the hood to see a large fire had started. My son, who heard the loud bang, came outside and saw the flames from under the hood. He ran into the house, grabbed a fire extinguisher, and attempted to put out the fire. He got the fire out but it was difficult. I had the car looked at by a mechanic and told me that the intake manifold had literally exploded. He has stated that he has never seen anything like this. It appears that the exploding manifold ruptured a fuel line. He told me there was a recall on this vehicle relating to a rupturing manifold and leaking fuel but that my vehicle had already had the recall performed. …

Completed full diagnosis at Vann York BUICK Gmc [redacted] after failing NC Inspection on [redacted]. Provided service fee of 202.00 approx. And was provided a list of services that required immediate attention. The service mechanic advised there were no recalls. The vehicle has failed twice since I picked it up from the dealership [redacted] due to a fuel issue. Once on [redacted] and at 7:45pm today [redacted]. My concern is that the recalls was not brought to my attention. I conveyed to dealership today after the failure on [redacted] the fuel filter was replaced. I inquired about the diagnostic today as well prior to the vehicle failing not sure if the part for the recalls is causing this issue but it would be such a relief to know the dealership should have caught the recall. Thank you for your service.

On certain passenger vehicles equipped with 3800 v6 (l36) engines and certain delphi fuel pressure regulators, the regulators have a much higher than usual rate of fuel leaks. A leak can allow fuel to enter the intake manifold through a vacuum line.
Remedy: Dealers will install new fuel pressure regulators with improved diaphragms. The recall will be conducted in phased mailings. Phase 1 began on June 30, 2004, and phase 2 began on September 30, 2004.
