What owners say across generations

Sentiment is mixed and heavily dependent on the specific generation, engine, and maintenance history. For the first-generation (W208, ~1997-2002) and second-generation (C209/A209, ~2003-2010) road cars, long-term owner reports indicate that well-maintained exa

  • Rust corrosion on body panels (doors, trunk, fenders) and suspension components — very frequent on pre-facelift models, recurrent on later models.
  • Aging interior electronics and actuators — includes failing AC vent motors (requiring dashboard removal), malfunctioning headlight leveling hydraulics, and general electrical gremlins. Frequency: recurrent.
  • Suspension wear — multi-link systems with numerous bushings and ball joints wear out, leading to vague handling and noises, though the car may still drive smoothly. Replacement is costly. Frequency: recurrent.
  • Engine-specific faults — M112/M113 V6/V8: potential for valve cover and PCV box leaks, rear main seal leaks (expensive). M272 V6 (post-2004): potential balance shaft defect (very expensive) and variable intake manifold failures. M271 Kompressor 4-cylinder: faulty timing chains. Frequency: recurrent for leaks; engine-specific faults vary.
  • Automatic transmission concerns — 5-speed automatic generally robust but can develop conductor plate issues; 7G-Tronic (7-speed) has a known design defect with the transmission pump that can lead to failure. Fluid neglect is a major risk. Frequency: recurrent.

Owner insights cover all generations of the CLK.
