Tl* the contact owns a 2004 pontiac bonneville. The contact stated that the air bag warning indicator illuminated. The failure occurred numerous of times. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 56,000.
Driving on highway, we (wide and I) noticed a smell of something burning. Since we were in a farming area we didn't think too much of it. About 20 miles later the smell lingered and we noticed smoke began filling car. Pulled over to see what was going on and my wife noticed smoke coming out from back seat. I took the seat off and discovered there was a fire going on in there. Pulled back seat out onto ground and put that fire out. Upon inspection we found the fuse box to be burned and melted. Obviously the care doesn't run any longer.
When the car would go over a bump the ignition switch would slide to the off position and all systems fail including the power brakes and steering. We have used 1 single key without a key ring since the incidents but still feel unsafe.
Tl* the contact owns a 2004 pontiac bonneville. The contact stated that the steering wheel would intermittently exhibit a clunking sound. Additionally, the steering wheel would seize for a few moments before independently resuming normal function. The vehicle was taken to the dealer but the failure was unable to be duplicated. The manufacture was not made aware of the failure. The vehicle was not repaired. The failure mileage was 42,000. The current mileage was 72,550.
Steel brake line started leaking.
In jan 2009 @ 72k miles on the car service engine light comes on and shortly after the trans. Would bang into gear. Per gm dealer it had codes p0756 and p2763 calling for replacement of shift solenoid. In sept. 2010 @ 108k miles the exact same issue and code, replaced the same part. Now in feb 2012 @137k miles again the same exact issue and codes, but this time they are saying to replace the trans. The first 2 times I went to the same dealer, this time I went to another. Issue I have is it sounds like this should have been replaced at 72k while under an extended 5 year, 100k mile warranty. Gm is unwilling to admit any fault or defect. I feel that this part failing 3x within 65k miles is an issue and should be investigated. Also looking thru some of the history I see this same type of issue in the 2003 cars.
Steering wheel clunked & felt detached---car taken to gm dealership where it was found to have quote a "broken steering column." steering column part was replaced, part #26087952 column as 6,518. Cost was $1516.58. Car was delivered on 3/15/05 and has only 40,662 + miles.
