Reliability, common problems and owner reviews for the Mercedes Benz GLA X156 GLA180 / 200 / 250 (M270 turbo). Check this before you buy used.

The turbocharged M270 petrols (the same family as the A/B-Class) give the GLA punchy, economical performance — a modern turbo direct-injection engine with the usual cautions: timing-chain wear on some early examples, direct-injection intake carbon over time, and turbo/PCV care. Paired with the 7G-DCT dual-clutch, so check the gearbox (shudder/fluid). Well-serviced examples are dependable; buy on documented history and a healthy DCT.
