Mercedes-Benz GLA 250 e
Joint development with Renault (H5Ht). Cylinder bore coating: NANOSLIDE. Compact and economical, but somewhat strained under high load. Also used as PHEV base (250e).
GLA 250 — SUV Surprise
160 kW and compact SUV dimensions: the GLA 250 H247 is surprisingly agile and makes genuine fun on a B-road.
Engine Weaknesses 5
Some M282 engines show early increased oil consumption from defective piston rings and oil scraper rings. The problem sometimes appears at low mileages.
Symptoms: Dropping oil level between service visits, occasionally slight blue smoke when accelerating
Some M282 engines show progressive oil consumption from low mileage. Cause: defective oil rings or pistons. Direct injection washes oil off the cylinder wall.
Symptoms: Regular oil top-ups required, no visible leaks, no smoke from exhaust
The M282 turbocharger can lose power at higher mileage from bearing wear or leaking charge air pipes. The wastegate actuator can deliver incorrect signals.
Symptoms: Power drop at full throttle, whistling in the engine bay, boost pressure too low warning (P0299)
The M282 1.3T (co-developed with Renault) shows similar thermostat problems to the predecessor M270 family. A simple replacement often does not resolve the issue permanently.
Symptoms: Engine does not reach operating temperature reliably, temperature gauge fluctuates, increased fuel consumption
As a direct-injection engine without port injection, the M282 lacks the cleaning action of fuel on the intake valves. Carbon deposits can impair gas flow from around 60,000 km.
Symptoms: Rough idle, slight power loss, occasional misfires on cold start
Vehicle Weaknesses 7
The 8-speed DCT in the GLA H247 occasionally shows jerky gear changes and delayed response when pulling away, particularly on cold starts in the GLA 180 and GLA 200. Problems increase from 50,000–100,000 km.
The reversing camera on the GLA H247 fails from around 30,000 km due to software errors or defective cable connections. Image appears with a delay, flickers or stays black.
On GLA H247 with power tailgate, sensors or actuators fail from around 50,000 km. Tailgate no longer opens or closes automatically.
Rear camera failures reported after 2–3 years or 25,000–40,000 km. Cause is often software errors or faulty cable connections.
GLA H247 with power tailgate shows sensor or drive motor failures from approx. 50,000 km. The tailgate can then no longer be opened or closed electrically.
In the GLA H247 the MBUX system occasionally restarts twice at the start of a journey. Additionally the brake assist and high-beam assist can deactivate themselves.
Like the predecessor X156, H247 owners report annoying wind noise at motorway speeds. Seals at the A-pillar or doors are usually the cause.
