The bolts which connect the cross-member of the trailer coupling device (towbar) to the vehicle may not have been tightened with the correct torque. As a result, the cross-member and the trailer could be completely detached from the vehicle, endangering the following traffic and increasing the risk of an accident.
The Mercedes-Benz GLC models affected by this recall were manufactured between 20 and 30 August 2018.
