This car has had very good care/maintenance, has not been driven hard, and has only 67,000 miles on it. While driving down a city street, approximately 35 MPH, the car began to sputter. I pulled in to a parking lot and shut the car off so that I could look at the spark plug wires. I had a spark plug wire loose when this happened once before. I had no over temp, I had normal oil pressure and there was no check engine light illuminated. I did not find a noticeable problem, but I could not get the engine to start again. I had it towed home. I changed the battery, the starter, and finally checked to see if the crankshaft would turn, which it wouldn't. I removed the spark plugs and tried it again. I got antifreeze from four of the cylinders! This was determined to be because of a failed intake manifold gasket.
1998 Pontiac Bonneville electrical complaints
Page 2 of 2: complaints 11 to 28 of 28, newest first, as owners wrote them.
1998 pontiac bonneville - on numreous occasions the vehicle has stalled for no apparent reason. Sometimes while moving, other times at stop signs or stoplights. Warm and cold weather. Warm and cold engine. The dealer has had it on the diagnostic machnies and even hooked up a recorder to record conditions when the stalls occur, but still no answers.
When the vehicle was started, it caught on fire. *jb
Turned ignition on and there was an explosion, and then a fire broke out in vehicle sitting there for 8 days before. Contacted dealer, and they offered to repurchase vehicle.
Traveling @65 MPH engine just shut off. Would not start until 3 hours later then it was hard to start. Problem was determined to be ground under passenger seat. Car still was hard to start now the deal claims it is the fuel pump regulator. Very upset with this experience. Other problems seem to have cropped up due to this ground problem such as alternator failure, headlights failing to the on positon, power windows would not work and of course the failure of the fuel regulator. This ground seems to be a major problem and I am surprised there has not yet been a recall. The common thread can be seen in the complaints lodged on your internet site.
Horn is difficult to apply in an emergency due to air bag assembly. Please give any further details.
Car would stall hard to start ground problem blamed for poor gas pressure to carb, also could of been problem that failed the starter, engine lite would go on then off, door locks would not work. Problem was intermitten until the last time when the ground problem was found. Major expense to me not happy it took this long to find problem. As of today car seems to be ok
This is the 2nd time I've had to replace the ignition coil wire and about 5/6 times already the car has just completely shut off while I was driving it, usually when I was slowing down at a stop sign/signal or just taking off from one.
On several occasions while stopping and then starting, vehicle idles low and on some occasions it stalls, especially while making left turns, dealer once found a vacuum leak from between the throttle body and upper plenumn, problem still exists. Consumer states vehicle has poor acceleration and lack of power. Battery failed.
From the night we drove the car home we had problems with the headlights/ dash lights and interior lights not working properly. Then we had trouble with the windshield wipers not working , horn. Upon repair work in march of 1999 we were showed and told that the dash had been broken out before and wires had been cut into. We have also had a problem with lack of power upon pressing accelerator.
Intermittently vehicle will suddenly accelerate or stall and die. Dealer has replaced the alternator generator and the ECM. Manufacturer will be notified.
The alternator at a stop cannot maintain power for more than aa couple of minutes and if you have an accessorie (I.e.) your heat or defogger or the headlights it will dim to the point that if you are at a long light it will stall the car and if it is dark it is hard for other cars to see you while stopped at a light it will stall out after a min. If you have a defogger on I don't believe that I should have to go to park when I stop at a light if I need the defogger on so I can see and the dealer just told me to put it in park at a long light and they have had two other complaints that they mentioned and tech support tells them there is nothing wrong with the chargeing system thank you for your time
Tire sidewall failed.
Radio failed.
Spark plugs failed on three occasions.
Intermittently while driving the vehicle shuts off, losing power brakes, power steering, etc. The dealer was not able to duplicate the problem. The computer was reprogrammed in february of 98. The problem still exists.
Horn is extremely difficult to engage, excessive physical effort is required.
While driving vehicle about 10 MPH and sometimes higher speeds, according to consumer, the vehicle just shuts off, losing power and steering power. The engine check light comes on when engine stops. Consumer had taken vehicle to dealer twice they said: the problem is with the fuel pump that's why the engine was not working. *ak consumer states that the fuel pump was not the cause of the problem, possible engine problem.
