Complaint volume by model year. Raw NHTSA totals, not adjusted for sales volume or time on the road, so older and higher-selling years accumulate more. Every year links to its full breakdown.
Highest: 2007 (53 complaints). Lowest: 2009 (9).
Sentiment is mixed and heavily dependent on the specific generation, engine, and maintenance history.
Leading to major failures; includes ignored transmission fluid, coolant, brake fluid, and spark plug intervals.
Includes failing AC vent motors (requiring dashboard removal), malfunctioning headlight leveling hydraulics, and general electrical gremlins.
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.
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.
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.
