Mercedes-Benz CLA (C117) Problems by Year
The first-generation Mercedes-Benz CLA (C117) is a style-led, four-door coupe spin-off from the A-Class that sold strongly in the UK due to its striking, miniature CLS looks. Positioned as a sleeker, more desirable alternative to a standard hatchback or compact saloon, it commands higher used prices and insurance premiums despite sharing all its mechanicals with the cheaper A-Class. It looks expensive on the driveway, but mechanically it requires the same cautious approach to DCT gearbox behavior, firm suspension wear, and electrical trim faults. It perfectly suits style-conscious buyers who want the prestige of a Mercedes coupe but need four doors and sensible running costs.

- ✓Test the 7G-DCT dual-clutch transmission for hesitant or jerky shifting; missing the required 3-year/30k-mile fluid change can lead to expensive failures.
- ✓Check the frameless door windows to ensure they drop a few millimeters when opening the door; failed microswitches will cause the glass to catch and damage the seals.
- ✓Inspect the interior trim for excessive creaks, particularly around the floating infotainment screen and the dashboard air vents.
- ✓On diesel models (particularly the OM651), listen for a brief rattle on cold startup, which could indicate a stretching timing chain.
- ✓Verify the condition of the sports suspension; the CLA is heavily sprung, meaning shock absorbers and top mounts wear quickly on potholed UK roads.
- ✓Check the boot for dampness, as the rear light clusters and boot seals can degrade, allowing water into the spare wheel well.
