Advice for buyers

What should I look for in a used Mercedes GLA-Class hatchback?

Despite the GLA's rugged bodywork, it’s still a good idea to check its extremities for scuffs. It’s unlikely to have been used off road, even the four-wheel drive versions, but it's worth a cursory glance at the undersides just to make sure there’s no damage there. Also check the alloy wheels for any kerb damage.

Inspect the interior for any damaged leather or scuffed plastics. Also make sure all the electrics work as they should.

Risk of fire

The high-pressure fuel lines on some cars made between 28 October 2015 and 19 November 2015 could crack over time and allow fuel to leak into the engine bay. In extreme circumstances, this could result in a fire. Any car affected by this recall will need to have new fuel lines fitted.

Oil leak

Certain diesel models manufactured between 1 February 2014 and 30 November 2014 have been found to suffer with a faulty oil seal that can result in a leak. If unchecked, the engine could be damaged by a lack of oil. A dealer will be able to let you know if your car needs to have a new seal fitted to solve the problem.

Engine may stall

A faulty engine part on cars made between 1 October 2015 and 31 November 2015 could cause the car to go into limp home mode or for the engine to cut out completely. A new part will need to be fitted to examples involved in this recall to prevent this from happening.

Overheating starter motor 

In the unlikely event the engine seizes up, the starter motor of cars built between 1 February 2014 and 28 February 2017 could overheat while repeatedly trying to start the engine. Speak with a dealer to find out if your vehicle is affected by this, because it will need an additional fuse added to prevent this from happening.

Vacuum lines

The vacuum lines going to the brake booster of vehicles assembled in the first year of production have been found to break, resulting in a loss of boost pressure after a couple of brake applications. Cars affected by this will need to have a more durable line fitted to stop this from happening.

NOx recall

All diesel models were subject to a voluntary recall in 2017 to apply software updates that aimed to reduce NOx emissions on any engine made before 2015. Contact a dealer to find out if your car has already had this work carried out; if not, book your car in to have it sorted.
