Fuel system, gasoline › Delivery

What 2000 Pontiac Bonneville owners say
Windows, wipers & sunroof all 57 →
2000 Pontiac Bonneville with 32,000 miles. The drivers side rear door window dropped out of track while driving. I do not use the rear windows and it was in the up position and not in use. So far I have taken it to a body shop and had them prop the window up temporarily. They advised me to get it fixed because of fear the side air bag May be affected by disconnecting the power to the window. I called the dealer in our town and asked if there have been others with this problem and they said not that they were aware of. I was told they don't sell the track separately from the whole assembly including the motor and the cost of parts would be at least $350.00. I know of another owner with the same year and model as mine and both of their rear windows did this in a matter of days of each other. He lives in my town and this makes me think it must be a widespread problem. …
I have had my 2000 Bonneville in the shop several times for various reasons. My radio had to be replaced, my drivers side window stopped working and they replaced the motor, now my passenger side window does not work and needs to be repaired. My trunk leaked and was told the extended warrenty did not cover it and the expense was on me. My air conditioner would blow cold air and then hot air or not blow cold air at all, it was in the shop 2-3 times for that. Now my car hesitates when speeding up and you can feel it jerking into gear when it shifts between 1st and 2nd gear or 2nd and 3rd. For this reason I had my transmission fluid replaced and an additive put in and was told this should take care of the problem. It has not!! My next step is to take it back to the dealership to find the problem. Is there anything I should know about concerning the transmission jerking, recalls,etc..?
Steering all 47 →
While driving the Bonneville the car will just shut down, looses all power. It has happened on the expressway and also just on local city driving. You can be going 30 MPH or 65 MPH. Car will just shut down (which is very scary going 65 MPH) and someone on your bumper. Looses power steering so its hard to move over lanes on the expressway, we have found you need to immediately put on emergency flashers, shift car into neutral and turn the key. Sometimes it will start on the first turn of the key but sometimes it takes multiple times of turning the key, all this while coasting on the expressway with people buzzing all around you. The one time it happened I was right by the garage we have been taking it to, took it over, they ran a check on the computer system and nothing came up. They are at a loss as to what to do without just start randomly changing parts they think it might pertain to? …
I feel the right steering wheel control arm is too close to the steering wheel, on my 2000 Bonneville. It is closer and longer that the turn signal arm on the left. I reported to Pontiac that any time I rapidly steer to avoid an accident, I hit this arm before the wheel. This slows my response and starts the windshield wipers. I find this is very bad at such a time, hitting the arm slows my response and the distraction from the wipers just adds to the problem. I suggest the arm be shortened about 3/4 inch, withdrawing it from the immediate area of the steering wheel. I had a minor accident a couple weeks ago, and I hit the arm. I can't say I would have avoided the accident without hitting the arm. But I distinctly feel, hitting it slow my ability to avoid the accident, and yes, my windshield wipers were going when the car stopped. …

This 2000 Pontiac Bonneville 3.8l with approximately 195K miles was operating normally over the last 72 hours. It had been driven approximately 300 miles between 12/16 and 12/18 @ 12:50 pm the date of the fire.that cold morning (8 degrees f) it was driven 10 miles rt @ 9 am, 20 miles rt between 10:30 and noon, and then sat for approximately 1/2 hour before it was driven 5 miles to a local store by my son. When he arrived at the store/gas station he parked near the pumps and when he shut off engine to go into store, smelled burning smoke from the front of the car. He opened the hood and was greeted by active flames coming from the front of the engine. The fire was subsequently extinguished and the burned part of the engine was the top and front left quarter (facing the vehicle). The anti-freeze reservoir was melted through.
Tl contact owns a 2000 Pontiac Bonneville. While driving at any speed, oil leaked onto the intake exhaust manifold. The contact referenced NHTSA campaign id number 07035, which states that drops of engine oil being deposited on the exhaust manifold through hard braking causes smoke that can ignite into small flames.
