Credov's researched list of the 3 faults the Mercedes-Benz GLA220d is known for (2012–2020), 2 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: In stop-start traffic and on the open road, watch for N appearing on the gear display on its own, or a stall.
Why it matters: A sudden, unannounced loss of drive while under way is a safety hazard, not just a repair bill, and the fix can range from a software update to a new control unit or clutch assembly.
What to look for: Creeping in traffic, pulling away gently and in a roundabout, feel for shudder, clunks or a slipping sensation.
Why it matters: Some shudder is normal for a dual-clutch design, but thumping into gear or persistent shuddering points to worn clutch packs, which wear faster with heavy town use and are an expensive repair.
What to look for: Lift the boot floor and press rear carpets, checking for damp, mould smell or standing water.
Why it matters: Water trapped under the carpets causes mould, rust in the spare-wheel well and electrical faults from wet wiring, and the carpets have to come out to dry it properly.
