Mercedes-Benz B-Class (2019)

Published on 01. 05. 2021

Problem description:

The air-conditioning system’s condensed-water drainage hose may be blocked, which may cause water to enter the vehicle’s interior. Consequently, any electrical components installed there could be corroded and/or subjected to short circuits or leakage currents.

As a result, the Supplemental Restraint System (SRS) control unit could stop working, the vehicle may fail to start, the engine emergency run could be activated while the vehicle is in motion, and the functioning of other components (e.g. the fuel pump, automatic/manual emergency call) could be adversely affected. This would increase the risk of injury and accident.

The Mercedes-Benz B-Class models affected by this recall were manufactured between 26 August and 10 October 2019.

What the owner should do?

If you read about a recall that you think may affect your car, you should make immediate contact with a Mercedes Benz dealer or workshop that’s been officially authorised to perform repairs on behalf of the manufacturer and ask for the details.

If you wish to know more about eventual problems of a specific car (e.g. real mileage, potential traffic accidents damages, odometer rollback, repairs, etc.), then we suggest going to HPI-Check.

Check the vehicle's history

UK car-owners can easily make a pre-check by visiting DVLA website and entering the car registration number; it will also reveal the car’s current MOT status.
