Which CL years have the most problems?
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.
Owner sentiment is highly conditional, centered on the significant and well-documented maintenance costs associated with the complex Active Body Control (ABC) hydraulic suspension system. The vehicle is universally praised for its timeless design, luxurious fe
Active Body Control (ABC) hydraulic suspension failures: includes leaking struts, failing accumulators (spheres), valve block issues, and pump failures. Very expensive to repair, with full system replacement sometimes required. Frequency: very frequent.
High general maintenance and repair costs: attributed to the car's complex technology and luxury status. Electronics, plastic engine bay components, and other wear items are costly. Frequency: very frequent.
Engine-specific concerns (varies by model year and engine): for 2007+ models (C216 generation, M273 V8), balance shaft sprocket/chain wear leading to potential engine failure is noted as a major issue. For the twin-turbo V12 (M275) and later V8s (M157), cylinder wall scoring and other turbo-related defects are mentioned as known risks. Frequency: recurrent.
Dynamic multi-contour seat failures: optional seats are very expensive to repair when their numerous adjustments fail. Frequency: recurrent.
Rust: mentioned as a concern for vehicles in certain climates, particularly underneath the car and around the rear axle. Frequency: isolated.
