Mercedes-Benz CLA (C117)

Production Years: 2013 - 20193 Documented Faults

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.
