On 3/15/10 the hood of my car was smoking. I contact GMC regarding recall on my Pontiac Grand Prix 2003. I was advised to take car in to dealer to get recall fixed. They claim they fixed the recall problem. I left dealer ship and the hood of my car caught on fire after leaving 5 min up the street to a service center. I was advised to tow my car back to the dealer. They are claiming the recall was fixed. However, the very same thing that the recall was for happened. I am in fear of driving this car again unless I know the problem was corrected. My concern is, if they claim the recall problem was fixed what caused the hood of the car to catch on fire. I am still waiting for them to resolve this issue. I am fearful for my safety of my life and others if my car is not repaired like they claim that it was the first time. Please advise me if there is anything that can be done to assure my safety and the safety of others.

The vehicle was towed to a repair shop and the mechanic stated that there was a lot of build-up in some parts of the engine. The mechanic further stated that these vehicles should be built to withstand these issues. The failure mileage was 100,000 and current mileage was 130,000.

Car caught on fire in garage 10 minutes after parking it. On checking the internet, there was a recall on this car, but I was not notified. NHTSA id #08V118000, issued 3/12/08. Owner's letters for recall not sent out by GM because of insufficient parts. "edmunds.com" web site indicates that there have been many incidents of fire, some reported to NHTSA. I have contacted GM and they have been unresponsive. Since I have insurance they feel that is sufficient. I am a senior citizen, my car was in excellent condition and paid for. Now I must purchase another car, incur debt, all because GM failed to notify me that there was a defect that needed to be fixed.
