Best Mercedes Benz Cls550 Years

The 2017 CLS550 represents the refined final year of the second generation with most issues resolved. The 2015-2016 models are also solid choices. For first-generation cars, the 2009-2011 models benefited from improvements to the M273 engine and suspension calibration.

Frequently Asked Questions

What is the CLS550 timing chain issue?

The M273 V8 in 2007-2011 CLS550s has a timing chain tensioner prone to failure, potentially causing catastrophic engine damage. Listen for chain rattle on startup. Preventive replacement costs $2,500-$4,000; waiting until failure costs the engine.

Is the CLS550 practical?

The swooping roofline limits rear headroom for taller passengers and reduces trunk space compared to the E-Class. It remains a four-door car with reasonable utility, but sedan buyers prioritizing practicality should look elsewhere.

How does the CLS550 drive?

The CLS550 delivers powerful V8 acceleration with composed handling for its size. It's more sporting than an S-Class but less aggressive than an AMG. The air suspension provides a comfortable ride with adequate body control.

CLS550 versus E550?

The CLS550 costs more and offers less interior space for similar mechanicals. You're paying for the styling. The E550 is the rational choice; the CLS550 is for buyers who value design over practicality.

What's the CLS maintenance cost?

As a V8 Mercedes with air suspension and complex electronics, expect $2,000-$3,500 annually in maintenance. Major items include timing chain service, suspension overhaul, and brake repairs. Independent Mercedes specialists reduce costs versus dealer service.
