Used Mercedes GLC 2015-present reliability
Category: Large SUV
The Mercedes GLC may not be as good an all-rounder as some of its rivals, but it's still well worth considering used.
What should I look for in a used Mercedes GLC estate?
The GLC will have been used in tight city-centre car parks, so it’s worth checking the bodywork for the minor scuffs that are easily picked up in such places, as well as carefully checking the alloy wheels for kerb damage. Check also the operation of the seats, especially in the rear, since these will have been raised and lowered often.
What are the most common problems with a used Mercedes GLC estate?
Some GLCs have been known to make noises when full lock is applied and the steering also seem to be susceptible to a problem known as ‘crabbing’, where the wheels on one axle of the car appear to be out of alignment with those on the other. The speed with which dealers have dealt with this has also been a source of concern, so it’s worth checking if any remedial action has been applied to any car you might be looking at.
There are three recall notices to check.
Reason for recall
Where the car incurs severe engine damage resulting in the engine failing to turn over (engine seizure) and if the driver repeatedly attempts to start the engine despite the engine not cranking the very high electrical current could lead to overheating of the starting current limiter and the potential for a fire.
How the manufacturer will repair
Recall the vehicles that are likely to be affected and install an additional fuse in the electrical line to the starter.
Reason for recall
Where a control unit coding was updated in a workshop between 3 December 2016 and 5 December 2016 the coding may not correspond to the specification and may trigger unplanned action in the vehicle. The safety and emissions systems may not react as design intent.
How the manufacturer will repair
Recall the vehicles that are likely to be affected and update the software in the corresponding control units.
Reason for recall
The propellant mix in certain seatbelt pre-tensioners ignitors may be incorrect. If the front seatbelt pre-tensioners are deployed the lock function of the pre-tensioners cannot be guaranteed.
How to check if the vehicle is recalled
Contact the local MERCEDES BENZ dealership or manufacturer. You will not need to pay for anything involving the recall.
How the manufacturer will repair
Recall the vehicles that are likely to be affected and replace the front seatbelts that are likely to be affected.
