What owners say
When I first got my car in 2012, had to take it back to place, because it cut off/ stalled. Bought as is. Had warranty for 3 months. They did not honor it. It has been one problem, after another. With this car. Since the day I bought it.
Vehicle began to run rough. Then immediately lost power steering and stalled. The engine died followed by flames from under both sides of the hood. No smoke was seen before the fire began. No lights came on to indicate a problem. In no time, the entire vehicle was engulfed in flames. The car was a total loss.
Tl* the contact owns a 1999 pontiac grand prx. The contact was driving approximately 20 MPH and approaching a traffic stop when the engine exhibited an abnormal increase in rpms. The vehicle was not taken to the dealer for diagnosis or inspection. On a separate occasion, the exact same failure occurred and the engine stalled before then independently restarting. The vehicle was taken to an independent mechanic for diagnosis. The technician was unable to duplicate the failure. The vehicle was not repaired. The failure persisted. The failure mileage was 131,752.
My 1999 grand prix gtp drives fine, then it will cut off sporadically. The most recent, I was driving 60 MPH on the highway, cuts off, battery light on, and oil light on, loses power steering and braking. Go to the shoulder. Put the car in park, turn the ignition off. A minute later starts back, driving on the highway for 5 minutes, does the same thing. It will stall at stop lights also, or when I'm going 20 MPH, whenever it wants. One time it would not start back up for 10 minutes. I have it at the dealership, they have found nothing, I've had 2 other mechanics look at it, they found nothing. I have googled the problem and found other complaints, but no recalls. And this has occurred 10 times or so in the past year. And has occurred in the previous years since I bought the car in 2007. It is frustrating when the mechanics tell me there is no error code in the cars computer.
Car over heats in stalled traffic. I have reviewed the overheating and car fire complaints in the "defects data base" and believe the main problem has not been identified: 'the computer will not call for full fan power' unless the A/C iis running.. Driving the car with the windows down on a warm day in stalled traffic, will raise the engine temperature as the cooling fans are both running in slow speed and will not go to the "high cool mode". But, turning the A/C on will speed up the fans to high and cool the engine. The computer should recognize the need for additional cooling with out the A/C having to be turned on. The increased engine heat due to this 'cooling system logic failure' will contribute to the oil leaks and engine fires that have already been reported to this agency. My vehicle, the radiator, fans, relays are all working as designed, and there are no diagnostic codes. Thus I am advising that this is a defect in logic with regard to controlling the high speed function of the radiator cooling fans. Having installed a new radiator recently and resealed the valve cover pans, I remain convinced that the problem is with the 'cooling circuit logic".
Dt*: the contact stated while driving 40 MPH, there was a clunking noise coming from the engine compartment. A warning light on the dashboard illuminated constantly. There was grey smoke emanating from the engine compartment. The vehicle was taken to a private repair shop, where the engine stalled. The mechanic determined that the upper intake manifold had cracked. The intake manifold casket kit, as well as six spark plugs were replaced. The manifold was also flushed repeatedly to remove sealant that had been in the manifold system prior to the incident. The repairs corrected the problem. Updated 10/18/2006 -
