The Best Years For Mercedes Benz Cls And Some To Avoid

Okay, here's a comprehensive article about the best and worst years for the Mercedes-Benz CLS, designed to be informative, helpful, and HCU-algorithm-compatible.

The Mercedes-Benz CLS-Class is a stylish "four-door coupe" that blends luxury, performance, and unique design. However, like any vehicle, some model years are more reliable and desirable than others. This guide will help you navigate the CLS range, highlighting the best years to buy and which ones to potentially avoid, ensuring a satisfying ownership experience.

Mercedes-Benz CLS Model Year Reliability Overview

Detailed Explanations

1st Generation (C219: 2005-2010)

The first-generation CLS (C219) introduced the "four-door coupe" concept to the Mercedes-Benz lineup. It was based on the W211 E-Class platform and offered a distinctive design. However, early models suffered from several reliability issues.

• 2005-2006: These years are the most problematic. The Airmatic air suspension is prone to leaks and compressor failures, resulting in expensive repairs. The Sensotronic Brake Control (SBC) system, while innovative, is complex and can fail, requiring replacement of the entire unit. Engine issues, particularly with the M113 V8 and M272 V6 engines, are also prevalent. The M272 V6 can suffer from balance shaft failures (a very costly repair), and the intake manifold flap actuator is also a common failure point. Electrical gremlins are also frequent.

• 2007-2010: Mercedes-Benz addressed some of the initial problems in these later years of the first generation. The M273 V8 engine is more reliable than the earlier M113. While Airmatic issues are less frequent, they can still occur. Overall, these models represent an improvement over the earlier years but still require careful inspection and maintenance.

2nd Generation (C218: 2012-2018)

The second-generation CLS (C218) continued the four-door coupe design with updated styling and technology. It was based on the W212 E-Class platform. While generally more reliable than the first generation, some early models still had issues.

• 2012-2014: These models can experience timing chain issues, particularly in the CLS550 equipped with the M278 V8 engine. Oil leaks are also a concern. Airmatic suspension failures, although less common than in the first generation, can still occur. The COMAND infotainment system can also be buggy and prone to glitches.

• 2015-2018: Mercedes-Benz made significant improvements to reliability in these later years of the second generation. The engines were revised, electronics were updated, and fewer issues were reported. The CLS400 and CLS550 (later CLS450) models are generally considered more dependable.

3rd Generation (C257: 2019-2024)

The third-generation CLS (C257) features a more modern design and advanced technology. It utilizes the MRA platform and offers a range of efficient and powerful engines.

• 2019-2020: Early models experienced some software glitches and minor electrical issues. The M256 inline-6 engine with EQ Boost is generally reliable but requires specific maintenance, including regular oil changes and attention to the 48V electrical system.

• 2021-2024: Further refinement and improved reliability characterize these models. The M256 engine is well-proven, and the updated infotainment system is more stable and user-friendly. These are generally considered the most reliable CLS models.

Frequently Asked Questions

Which CLS generation is the most reliable?

The third generation (C257, 2019-2024) is generally considered the most reliable, with fewer reported issues and more advanced technology.

What are the common problems with the first-generation CLS?

Common problems include Airmatic air suspension failures, SBC brake system failures, engine issues (balance shaft, intake manifold flaps), and electrical gremlins.

Is the Airmatic suspension reliable on the CLS?

The Airmatic suspension is a known weak point, especially in the first and early second-generation models. Regular maintenance and inspection are crucial.

What should I look for when buying a used CLS?

Thorough pre-purchase inspection by a qualified mechanic, focusing on the engine, transmission, suspension, brakes, and electronics, is essential. Review the service history carefully.

Are the V8 engines in the CLS reliable?

The M113 V8 in the early first-generation models can be reliable if properly maintained, but the M272 V6 is more prone to issues. The M273 V8 (later first-gen) and the M278 V8 (second-gen) are generally more reliable, but timing chain issues can occur in the M278. The M256 inline-6 (third gen) is proving to be quite reliable.

What is the SBC brake system, and why is it a problem?

SBC (Sensotronic Brake Control) is an electro-hydraulic braking system used in early CLS models. It's complex and expensive to repair or replace when it fails.

Is the COMAND system reliable in the CLS?

The COMAND infotainment system in the early second-generation CLS models can be buggy and prone to glitches. Later versions are more stable.

Conclusion

Choosing the right Mercedes-Benz CLS requires careful consideration of the model year and its associated reliability. While the earlier models offer a more affordable entry point, be prepared for potential maintenance costs. Opting for a later model, particularly from the third generation, provides a more reliable and technologically advanced experience. Always prioritize a thorough pre-purchase inspection to ensure a satisfying ownership experience.
