Grand Prix LX 3.2L V6

  • Automatic transmission

My new key worked fine, her original key did not.

My wife would try and start the car with her key and get mad when it would not start. I would try my key and car ran like a top.

Grand Prix V6

  • Automatic transmission

My Pontiac just cuts out, I can be driving along and then for no reason it decides to shut down. It started as a minor annoyance in that it would stall at traffic lights so we took it to a mechanic who replaced a sensor and filter charged us 500 dollars and said it was fixed. A week or two later same thing brought it back and another sensor replaced, car was left running for a few hours and didn't stall so we got the car back along with a bill for a further 600 dollars.

1 month later car starts to stall every time I'm driving but is behaving for my husband so we thought it was the electrics in the seat maybe shorting out when I moved the seat up. during the next few weeks the car stalls at traffic lights on him a couple of times, so we bring it to another mechanic who replaces all the above sensors and gives us yet another bill, this time for 850.

Now the problem has progressed to just stalling for no reason or warning while he's driving. Finally it started stalling and knocking out the steering and the brakes so we can't get to the verge or avoid the car in front if it decides to stop.

Anybody else have this problem and find a solution, apart from this problem I have loved this car and would like to keep it but not if it's going to continue to be this erratic. This is dangerous, we could be hurt or God forbid hurt some one else. Needless to say we are no longer driving this car but I would love to fix it rather than replace the car if I could

This car has had a stalling problem since we bought it last June 09. Just 2 days after it stalled and wouldn't start, thank god it was under warranty. Anyway, it has been in the shop 5 or more times just to find the problem and we have had a new computer, 2 fuel pumps, fuel resistors, fuel relay switch, 2 fuse boxes which is a discontinued part and has to be used, starter, supercharger just to name a few and it still had a problem. It seemed like every time we got it back from the repair shop that same day it would stall no sooner than an hour or less. At which time I was told to pound on the fuse box. Go Figure! This last time they found a frayed wire behind the fuse box which they replaced. So hopefully this time it has cured the problem. Otherwise, we think it might be the crankshaft positioning sensor. But unless it shows its code on the diagnostic the warranty won't cover it and I sure ain't gonna pay for it. So, if anyone has an answer to my problem PLEASE let me know. There have been numerous times I have wanted to just shoot the damn car!!!! My worst fear is that it stall on a windy mountainous road with no turnouts.

Grand Prix SE 3800

  • Automatic transmission
  • 77,000 miles

Shortly after the car was purchased for my college student son in January of 2010, the engine would quit when slowing down once every few days. The dealership replaced the mass airflow sensor but that didn't solve the problem. A few stalling episodes later, the engine would quit repeatedly even when accelerating and multiple times on the same trip. The engine could be restarted shortly after pulling off the road in all instances. No further episodes occurred after the crank position sensor was replaced. Cost: Mass air flow sensor: $250. Crank position sensor: $300.

Grand Prix GT 3.8L N/S

  • Automatic transmission
  • 75,000 miles

car can run great for an hour or for several days, then, when slowing down for a turn or stop light, the car just shuts off. i am suspecting the crank position sensor, but have not replaced it yet, because the car is just finishing up a 3 day run with no problem. BUT, i am sure it is going to stall on me in the next day or so. there is no "check engine" light with this problem, so i'm just guessing.

Grand Prix GTP 3800

The car will stall out and the steering wheel and brake pedal locks during while braking, this could be dangerous; I have already loss control of the vehicle and rolled into a curve during a turn. I don't know if this is related, but the traction control light has been on for a while.

(reported on)

Grand Prix GT 3.8

  • Automatic transmission
  • 90,000 miles

Failing MAF can be dangerous - in my case the engine stopped as the car entered a major road and without power steering I had to glide the car to the bike lane. The car was towed to a Pontiac dealer who charged $450 for 20 minutes work and a part that costs $150.
