We went in for a routine oil change, when the mechanic advised that there was antifreeze in the oil. The intake gasket was leaking. Our car only has 70,000 miles on it. Mutual friends of ours, also had the same problem with previous Grand Am around the same mileage.

Pontiac gram am 2003, now has 75,000 miles. Low coolant light turned on. Contacted dealership and was told to add manufacturer brand coolant. A week later low coolant came back on and added more coolant. Took into shop for repair and was told that coolant was leaking into the engine manifold and will need to be replaced. Cost of the repair $1,250. They told me that seal gasket was worn out and caused the leak in to the engine and it happens when car reach a higher mileage. I believe this is a design flaw and should have been corrected from the year 2000 models. This same problem caused my other car Pontiac Grand Am 2000 to die out at 80,000 miles and only that time the warning was engine light came on before the car died and would not start again. I don't see this type of a problem with other car manufacturer even if the car reach mileage 60,000 - 80,000 miles.

We purchased a 2003 Grand Am from gunn Pontiac in san antonio in August 2003. Within a month the car would stall out at stops or during turns. We brought the car in twice to the dealership and was told that they couldn't duplicate the problem. The car has done this for the last 11 months on and off. In July 2004 the slave cylinder went out and I was told that it would be $1200 to repair it. The service consultant told me the 2 problems could be related because he had never seen this part go out at 40,000 miles and that the cylinder should last much much longer. Once the car was repaired I was then told that the dealership would not help us w the repairs. I talked to the service manager, who basically called me a liar about the problem w the car stalling and that I would have to take this problem up w Pontiac national reps. After 2 and a half weeks of no answers from them we went and picked up the car on Friday(8/20/04). Tonight the car stalled out 4 times on a drive. I an discussed w Pontiac and their lack of service!!

Grand Am 6-cyl

  • Automatic transmission
  • 2,624 miles
Purchased 2003 Pontiac Grand Am SE1 with 3.4 liter 3400 sfi V-6 engine on 7/30/03.N 8/27/03, 2624 miles on vehicle. Experienced major problem of car died out and stalled while driving was able to restart auto which would died out and stalled 6 separate times this occurred while driving and ranged from 15 seconds to 2 mins of driving time and at speeds of 5 to 35 mph. ( the vehicle just quit running with no warning!) had vehicle towed to dealership. Dealer service advisor (joe) advise me that at the repair bays they experienced/duplicated the problem 9 times, but had no idea what was causing the problem. Stated they had calls into General Motors technical support and were waiting for some possile answers/solutions. I am reporting this of two reasons 1. this is a major safety problem. The vehicle dies/stalls out at the wrong time and place an accident will happen. 2. I am with out a vehicle which I purchased in good faith. (still setting in the shop).
