2003 Pontiac Bonneville common problems

The most-reported problem areas across all 67 owner complaints filed with NHTSA — and what to check before you buy.

Steering
Steering should be tight and centered — no play, clunks or wandering. Test at low and highway speed; listen for power-steering whine.
Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Engine And Engine Cooling
Check coolant level and color, look for leaks, and confirm the engine reaches normal temperature without overheating.
Engine
Listen for knocks or ticking, check for leaks and blue/white exhaust smoke, and make sure it doesn't overheat. No check-engine light should be on.
Power Train
Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.
Fuel System
Sniff for fuel odor, check for leaks, hard starts or stalling, and confirm the fuel gauge reads correctly.
