2009 Mercedes-benz SLK-Class common problems

The most-reported problem areas across all 3 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.

Electronic Stability Control (esc)

Have a trusted mechanic inspect this system as part of a pre-purchase inspection.

Service Brakes

Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.

Tires

Check tread depth, the DOT age date, and that all four tires match with even wear. Look for bulges or cracks.
