My husband and I bought our college son this car because I had a bonneville in 2002 that I loved and it seems to be a good car. This car of my sons however stalls out while he is driving and it even happened on the freeway. That is horrible! We have had it taken in several times, but it never shows up as anything. This has happened at least 10 times in the past year and seems to be a very dangerous problem. It stalls out, then will start after letting it sit several minutes.My husband and I have drove it and it happened to each of us a time or two also.

I have a 1994 Pontiac Bonneville, the engine dies when slowing down,it might happen several times in one day or go a few weeks and be ok. It stopped once slowing down to get on the expressway, very scary.it happens sometimes not long after starting or can drive 20 miles before doing it.has done it going down a curvy road,of course no power steering or brakes, had it put on a analyzer, showed nothing. please any help would be very much appreciated.

Update from Feb 14, 2011: engine quiet again today when slowing down, this is very dangerous and no one seem to know how to fix it,.pontiac needs to fix this problem or teach the mechanic's how to fix it. to many complaints on this problem, someone will get killed in these cars, then it is to late.are they just throw away's ? surely there is a fix here.

Update from Jun 6, 2011: in shop 2 weeks , do not know what the problem is, again, dangerous when car die's while going 20 to 25 miles a hour, come on somebody , pontiac, fix this problem, to many complaints, and no one knows how to fix it, people have had parts replaced to still have the same problem, stand behind your product, I guess I will buy a ford.

My Bonneville stalls while driving, try to restart and only turns over, then 3 minutes or so later it starts right up. Then after running for a while, I turn it off , perhaps run into a convenience store try to start again and it won't start then give it another 3 minute rest and immediately starts up. It is not showing any codes when tested. One mechanic thinks its the sock around the fuel pump????

Can anyone help me out on this, it seems impossible and i love the car otherwise. Thank You

1994 Pontiac Bonneville keeps stalling while we are driving. I'm worried that it may cause an accident. We have had the sensors replaced, filters, and checked for electrical problems. There was one electrical problem with the altenator, it was incorrectly wired over the motor.

Left it at the auto shop, they drove it for a long time and it never did it to them. Diagnostics showed that there wasn't a problem. There must be something wrong.

Just wanted to know if anyone else has had this problem and what did you do to fix it.

Car stalls while driving most of the time when you take your foot of the gas.

Have replaced the oxygen / EGR / crank sensor / Gas filter and gas lines. Tried replacing the computer, problem still there. Have had to garage 3 times,They even checked for broken wires

said there is nothing showing wrong. Have no idea where to go next can anyone help.

for the past year my car just stops while driving... many close calls by nearly being rear ended. i took it into the dealer & they said it was the battery.... so of course after the $250 bill that was not the problem!!! i took it back and they had it for 5 days and said nothing was wrong....then again for 3 days always approx. 3 weeks apart... the last time i took it in they said oh yeah it now stops for them too... said it was the oxygen sensor. it was ok for nearly a week...WOW!!! it is right back to the same thing. seems to die more often while waiting at a stop light but will still just die while driving... anyone know what the problem is? thought the dealers would, but no luck with them... help!!!! thanks
