Mercedes-Benz Cla Years to AvoidThe weakest years — and the one you should buy instead
After reviewing every Mercedes-Benz Cla we've analyzed (12 years), these are the 3 weakest. Each one has either an absolute low reliability score, chronic repair issues, or unusually high ownership costs relative to other Cla years.
Proceed with caution
2014 Mercedes-Benz Cla
The 2014 Mercedes-Benz CLA, while visually appealing and offering brand prestige at an accessible price, represents a high-risk proposition for used car buyers. Its early model year status means it is frequently plagued by significant dual-clutch transmission issues and various electrical gremlins that can lead to extremely costly and frustrating repairs. Proceed with extreme caution and a substantial repair budget if you're considering this vehicle.
Why this year scores low
Known for rough shifts, hesitation, shuddering, and eventual failure of clutch packs or the mechatronic unit. TSBs exist but repairs are expensive and sometimes temporary.
Malfunctions with the COMAND infotainment system, intermittent warning lights (ESP/ABS), faulty sensors, window regulator failures, and parasitic battery drains are common. Can be complex to diagnose.
Premature wear of front control arm bushings, strut mounts, and sway bar links leading to clunking noises, especially over bumps, and reduced ride quality.
Proceed with caution
2015 Mercedes-Benz Cla
The 2015 Mercedes-Benz CLA is a stylish entry into luxury, but it carries a higher risk profile than its more established stablemates. While it offers undeniable curb appeal, be prepared for potential electrical gremlins and a particularly finicky dual-clutch transmission that can lead to significant repair bills if not meticulously maintained. This car requires a careful buyer with a healthy budget for its specialized care.
Why this year scores low
The 7-speed dual-clutch transmission is prone to rough shifts, hesitation at low speeds, and premature wear of the clutch packs or mechatronic unit. Issues often stem from software glitches or internal component failure.
Owners frequently report infotainment system freezing or glitches, recurring battery drain issues, and various sensor failures (e.g., ABS, wheel speed, camshaft position). These can be difficult to diagnose and costly to resolve.
While generally robust, the 2.0L turbo engine can suffer from turbocharger actuator failures, oil filter housing leaks, and issues with the PCV valve or camshaft position sensors, leading to performance degradation and warning lights.
Proceed with caution
2018 Mercedes-Benz Cla
The 2018 Mercedes-Benz CLA, while offering undeniable style and brand cachet, demands a cautious approach from buyers. It sits in a high-risk category for electrical and transmission issues that can quickly escalate ownership costs. If you're drawn to its aesthetics, understand that diligent pre-purchase inspection and a robust maintenance fund are non-negotiable.
Why this year scores low
Owners frequently report issues ranging from infotainment glitches, faulty sensors (camshaft, crankshaft, wheel speed), battery drain, and random warning lights. Diagnostics are complex and parts expensive.
The 7-speed dual-clutch transmission (DCT) is a known weak point. Common complaints include rough shifts, hesitation at low speeds, clunking noises, and in more severe cases, mechatronic unit failures or clutch pack wear. Fluid changes are critical and often overlooked.
While generally robust, the 2.0L turbo engine is susceptible to oil leaks, particularly from the valve cover gasket and oil filter housing. The PCV (Positive Crankcase Ventilation) valve can also fail, leading to oil consumption or rough idle.
