Grand Prix

  • 120,000 miles
The contact owns a 2003 Pontiac Grand Prix. The contact stated that the brakes failed intermittently. While idling at a red light, the engine revved and the vehicle stalled. The vehicle was taken to the dealer twice, but they were unable to duplicate the failures more than once. In addition, the key would become stuck in the ignition and prevent the vehicle from being started. The vehicle was not repaired and the manufacturer was notified. The approximate failure mileage was 120,000.

While I'm personally unaware of any crashes or people dying due to this problem on this model, GM has a well documented history of bad ignition switches on other models that are not included in the recall that they have known about for many years. The effects of the bad ignition switch with this model are: 1. the A/C - heater fan blower works intermittently, if you're lucky, and then only on high speed if it does. None of the other speeds work at all. 2. when you try to turn the fan motor on to run the heater or A/C, the headlights go out. While there are different schools of thought on the cause, after researching the internet, one component seemed to correct the problem every time. You must replace the ignition switch. The problem is not the resistor as some seem to think, but the ignition switch. Those who replaced the resistor always had to come back and replace the ignition switch. Those who replaced the ignition switch had fewer, if any, problems after that. I write this to you because I believe someone "up there" needs to know this information. I simply hope it doesn't fall on deaf ears like most things. I withhold further comment. Regards, [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)
