Has the 2015 Mercedes-Benz G-Class been recalled?

Is the 2015 Mercedes-Benz G-Class recalled in the UK or Europe?
Recalls issued by the UK's DVSA and through the EU's Safety Gate system that cover this model and build period. European models can differ from U.S. ones, and "years estimated" means the recall gave no build dates, so confirm your own car with your registration or VIN.
UK DVSASmall cracks may appear in the brake pipes
Risk: Cracks may develop in the brake pipes to the ABS unit.
Fix: Modified brake pipes with an optimized routing will be fitted.
UK DVSAElectronic stability program (esp) may malfunctionYears estimated
Risk: Affected vehicles will have the manufacturer's DISTRONIC PLUS system fitted. In the event communication between this system and the ESP is lost the systems responses such as engine torque may be adversely affected for the period of the communication loss.. The braking system will not be affected though more effort may be required.
Fix: On affected vehicles update the ESP software.
UK DVSASteering column coupling may not be tight
Risk: Insufficient tightening of the steering column coupling could lead to wear of the steering coupling during use. In case of excessive wear of the steering coupling the coupling eventually may not transfer the effort the driver inputs to the steering to the steering gear in which case the steering control would be lost.
Fix: Recall the vehicles that are likely to be affected and replace the steering column coupling.
UK DVSAFront and/or rear axle bolts may not be tightened correctly
Risk: The front and/or rear axle mounting bolts may not be tightened to the correct specification. The bolts may break and could affect control of the vehicle.
Fix: On affected vehicles replace the front and rear axle carrier bolts.
UK DVSAFront passenger airbag may be deactivated
Risk: Under certain conditions the front passenger air bag can be deactivated and may not deploy in the event of a collision.
Fix: On affected vehicles check and if necessary update software.
UK DVSAEngine may cut out
Risk: On model series 463 with a 6 cylinder diesel engine the engine wiring harness may make contact with one of the brackets in the engine compartment and chafe by vibration during driving. Depending on the wire affected the engine MIL lamp could illuminate the engine could run in limp-home mode or the engine could cut out increasing the risk of collision.
Fix: Recall the vehicles that are likely to be affected and replace the bracket in the engine compartment and where necessary correct the routing of the engine wiring harness.
UK DVSAFire may occur
Risk: The cylinder head of the high pressure fuel pump may not be to specification. During operation of the pump cracks can form and eventually fuel may leak. Escaping fuel could lead to the engine stopping and fuel leaking in exceptional circumstances could lead to a fire.
Fix: Recall the vehicles that are likely to be affected and replace the high pressure fuel pump.
EU Safety GateThe oil supply to the drive shaft bearing in the rear axle differential may be inadequate, which could lead to that the car suddenly loses…The oil supply to the drive shaft bearing in the rear axle differential may be inadequate, which could lead to that the car suddenly loses speed, creating a risk of an accident. Moreover, the rear wheels may lock, resulting in a loss of vehicle control and/or transmission oil may leak or vehicle parts may fall onto the road, endangering other road users.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateFaulty configurations of the control units (traction systems, signal recording triggering modules, engine control units and headlights)…Faulty configurations of the control units (traction systems, signal recording triggering modules, engine control units and headlights) could cause one or more control units to malfunction, which could increase the risk of an accident. The exhaust emissions exceed the legal limits, posing a risk to the environment.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateThe software of the Electronic Stability Programme (ESP) could malfunction.The braking and/or stopping distance could be lengthened as a result. This could increase the risk of an accident.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateThe universal joint gear may be subject to excessive wear due to insufficient torque in the screw connection of the steering coupling.As a result, the transfer of the desired steering torque might no longer be assured. This could result in the loss of rotational torque transfer between the steering wheel and the steering box which would make it impossible to steer the vehicle.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateFollowing the update of the control unit coding, the coding parameters of the control unit could be defective.This could give rise to various unplanned reactions in the vehicle: the wrong airbag could be triggered in the event of an accident, the airbag control unit may not recognise the belt buckle status, the engine control unit could be coded with a false maximum speed or various assistance systems may not function.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown

DIFFICULTY OPENING MAIN DOOR HANDLES. THEY ARE VERY FRAGILE AND I JUST HAD THEM REPLACED. THEY STICK WHEN OPENING. I SEE PREVIOUS MODELS HAVE SIMILAR ISSUES WITH THE DOOR HANDLES. IT COST $500-$600 EVERY TIME WE REPAIR THEM. *TR

AFTER 14 MONTHS OF OWNERSHIP AND 12,500 MILES, THE AUXILLARY BATTERY STOPPED WORKING. WITHIN 5 DAYS OF THE WARNING LIGHT INDICATING NO AUXILLARY BATTERY, VEHICLE STALLS WHILE DRIVING (IN MOTION AND STATIONARY), FEATURES LIKE DISTRONIC (CRUISE CONTROL THAT FEATURES DISTANCE FROM THE CAR IN FRONT OF YOU) STOPPED WORKING. BOTH OF THESE ARE SAFETY CONCERNS AS THEY CAN CAUSE SERIOUS ACCIDENTS WHEN THEY OCCUR. DEALERSHIP INFORMED ME THAT THIS WAS A COMMON OCCURRENCE ON 2015 MODELS. THEY ALSO INFORMED ME THAT THIS WOULD BE A RECURRING PROBLEM THROUGHOUT OWNERSHIP. I DO NOT FEEL SAFE WITH MY CHILDREN…

Counts are a starting point, not a verdict: popular models collect more complaints because more of them are on the road, and NHTSA does not verify individual reports. To see whether a recall is still open on your car, enter your VIN at nhtsa.gov/recalls (U.S.) or your registration at check-vehicle-recalls.service.gov.uk (UK). Had a safety problem? Report it to NHTSA; complaints are what trigger investigations and recalls.
