Common CLA-Class Problems by Generation
2014–2019 CLA-Class (C117 Chassis)
This first-generation CLA featured front-wheel-drive or 4MATIC options, turbocharged inline-4 engines (M270/M133), and bold coupe styling. However, it wasn’t immune to growing pains.
🔧 Known Issues:
- Timing Chain Tensioner Noise (CLA250 – M270 Engine):
Early M270 engines are prone to rattling timing chains, especially if oil changes were delayed. This can cause camshaft wear or even engine failure if ignored. - Turbocharger Wastegate Rattle:
A metallic ticking noise on cold starts is often due to a worn or loose wastegate actuator. It’s annoying—but fixable. - Coolant Hose Leaks:
Weak hose clamps on 2014–2016 models often lead to slow coolant loss and overheating if not caught early. - 7G-DCT Transmission Jerking:
The dual-clutch automatic can hesitate or jerk, especially in stop-and-go traffic. Often tied to outdated software or worn clutch packs. - A/C Blend Door Malfunction:
Some models suffer from inconsistent cabin temps due to broken blend door actuators buried deep behind the dash. - Electronic Power Steering Failures:
An occasional issue where EPS units fail without warning—usually resulting in heavy steering or error lights.
2020–Present CLA-Class (C118 Chassis)
This generation introduced sharper styling, an improved MBUX infotainment system, and more powerful engine options—including AMG CLA 35 and CLA 45.
🔧 Known Issues:
- Infotainment Freezing or Reboots (MBUX):
Widespread reports of touchscreens lagging or rebooting. Often resolved via software updates or replacing a faulty head unit. - Active Brake Assist Warnings:
False alerts can occur when driving in the rain or near reflective road signs. Mercedes issued multiple software patches. - AMG Engine Mount Failures:
High-performance CLA 45 models can suffer from early engine mount wear, causing vibration and noise under load. - Premature Rear Tire Wear (CLA 250 4MATIC):
Misaligned rear suspension geometry can cause tires to wear unevenly—even with low mileage. - Sunroof Rattle or Wind Noise:
Loose trim or faulty seals around the panoramic roof can lead to annoying rattles at highway speed.

FAQs About Mercedes-Benz CLA-Class Repair
Is the Mercedes CLA-Class reliable?
Yes, especially the 2017+ models. The CLA offers strong engines and good build quality, but like all turbocharged Mercedes models, they require consistent service and early issue detection to stay reliable.
Why does my CLA jerk when accelerating?
It’s often related to the 7-speed dual-clutch transmission (7G-DCT). Software issues, clutch wear, or outdated adaptation values can cause jerking, especially at low speeds.
What does a timing chain rattle mean?
If you hear a metallic rattling on cold starts, your timing chain or tensioner could be worn. This is common on early CLA250s and should be addressed immediately to avoid engine damage.
How often should I change the spark plugs?
Every 60,000 miles is standard for gasoline CLA models. Neglecting spark plug replacement can lead to misfires, reduced fuel economy, and catalytic converter damage.
Can I service my CLA AMG model here?
Yes. We have experience with both CLA 35 and CLA 45 AMG trims, including performance brake systems, turbo diagnostics, and specialized cooling systems.
Is the MBUX infotainment system repairable?
Often, yes. Software updates may resolve glitches. For persistent issues, we can replace individual modules rather than the entire system.
