2004 Pontiac Bonneville common problems

Owners have filed 28 complaints with NHTSA. These are the most-reported areas in a sample of the most recent — and what to check before you buy.

Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Steering
Steering should be tight and centered — no play, clunks or wandering. Test at low and highway speed; listen for power-steering whine.
Air Bags
Confirm the airbag light turns on then off at startup — if it stays lit there's a fault (costly, and a safety risk). Check for signs of prior deployment.
Power Train
Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.
Service Brakes
Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
Latches/locks/linkages
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
