2012 Mercedes-benz SLK-Class common problems

The most-reported problem areas across all 12 owner complaints filed with NHTSA — and what to check before you buy.

Fuel/propulsion System
Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
Structure
Inspect for rust, fresh undercoating, mismatched paint, uneven panel gaps and any sign of prior collision or frame repair.
Wheels
Inspect wheels for bends, cracks and curb rash, and feel for vibration at highway speed.
Seats
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
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.
