1999 Pontiac Bonneville common problems

Owners have filed 158 complaints with NHTSA. These are the most-reported areas in a sample of the most recent — and what to check before you buy.

Gasoline
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Fuel System
Sniff for fuel odor, check for leaks, hard starts or stalling, and confirm the fuel gauge reads correctly.
Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
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.
Fuel/propulsion System
Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
Engine And Engine Cooling
Check coolant level and color, look for leaks, and confirm the engine reaches normal temperature without overheating.
