Mercedes-Benz GLA200 common problems: what to check before you buy

Credov's researched list of the 6 faults the Mercedes-Benz GLA200 is known for (2012–2019), 5 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.

Known problems on the Mercedes-Benz GLA200

DCT drops to neutral or stalls

Safety risk

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.

4MATIC rear diff noise

Costly if missed

2014–2019 · Drivetrain

What to look for: In tight circles and pulling away briskly, listen and feel for clunks, thumps or grinding from the rear differential.

Why it matters: Mercedes' own 2015 workshop guidance says the whole rear differential assembly is replaced once this fault is confirmed, which runs into the thousands of dollars.

DCT low-speed judder

Costly if missed

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.

M270 PCV valve fails

Costly if missed

2013–2019 · M270 · petrol · Engine

What to look for: Listen at idle for a whistle or hiss from the top of the engine, and check for a check-engine light.

Why it matters: Owners commonly need the whole valve assembly replaced more than once, often quoted at over US$1,000 at a dealer.

M270 water pump/thermostat

Costly if missed

2013–2019 · M270 · petrol · Engine

What to look for: Watch the temperature gauge settle and stay normal on the drive, and check for coolant crust around the pump.

Why it matters: Driving on with an overheating or unstable-running engine risks a warped cylinder head or a blown gasket, and the thermostat's position at the back of the engine makes the job dearer than it looks.

Boot and footwell water leak

Minor

2012–2020 · Body and structure

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.
