What owners wrote
A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
Vehicle was parked when consumer stuck key into ignition and the driver's side air bag deployed. Consumer does not know if air bag was repaired.
While driving vehicle was involved in a collision. Driver's seat belt did not retract, driver sustained minor injuries.
A dear friend of mine had an accident a few days ago deploying the passenger side airbag resulting in the windshield being busted to an extent that it not being able to see through .. Shouldn't this be a recall .... She owns a 99 pontiac bonneville SRS.
I've had major problems with my 99 bonneville, costing me over $2,400. It started at 64,000 miles (6/26/02) with a backfire caused by a faulty fuel pressure regulator, which now has a service recall (a little too late); that cost me $300. A week later, the upper manifold plenum leaked causing the engine to flood and die; I spent over $500 on that little project (replacing the manifold and cleaning the engine).
Noticed smell of gas when auto parked in garage..further investigation noted that fuel leaking from fuel line..took auto to dealer and dealer stated that both fuel lines have deteriorated, causing the leaks..while I have been familiar with fuel leaks from loose connections, I can not imagine how fuel lines can not been built to last.
