Mercedes-Benz CLS (C218) Problems by Year
The second-generation Mercedes-Benz CLS (C218) is a refined and stylish four-door coupé (and stunning Shooting Brake) that shares most of its reliable mechanical components with the E-Class W212. Positioned to offer the practicality of a saloon with the swooping elegance of a coupe, it commands a premium over the E-Class but holds its value well in the UK market. Overall, it is highly reliable and makes for an exceptional long-distance cruiser. However, diesel emissions hardware, Airmatic suspension on higher trims, and 7G-Tronic gearbox issues are the main watch-outs, making it perfect for style-conscious executives.

- ✓Check the OM642 V6 diesel engine for oil leaks around the oil cooler in the V-valley, a common and labour-intensive fix.
- ✓Test the Airmatic air suspension (standard on the rear of the Shooting Brake and V8 models); ensure it doesn't drop overnight.
- ✓Inspect the frameless door windows; they must drop slightly when pulling the handle to clear the weather seals and prevent wind noise.
- ✓Verify the 7G-Tronic automatic gearbox shifts smoothly and check the history for the vital 40,000-mile fluid and filter changes.
- ✓On diesel models, check for AdBlue or DPF warnings, especially if the car has been used primarily for short urban trips.
- ✓Examine the alloy wheels for cracks; the CLS uses large wheels with very low-profile tyres, making them susceptible to pothole damage.
