2003 Cadillac Seville common problems

The most-reported problem areas across all 27 owner complaints filed with NHTSA — and what to check before you buy.

Engine And Engine Cooling
Check coolant level and color, look for leaks, and confirm the engine reaches normal temperature without overheating.
Suspension
Listen for clunks over bumps, check the car sits level, and look for uneven tire wear and worn shocks or struts.
Structure
Inspect for rust, fresh undercoating, mismatched paint, uneven panel gaps and any sign of prior collision or frame repair.
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.
Service Brakes
Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
