Recall summary

Water forms as a typical byproduct of a car’s air conditioning system and is diverted away from the car down to the ground through a drain hose. In the affected vehicles, the drain hose may be incorrectly installed, causing water to leak inside the cabin through the front passenger footwell.

The component involved in this recall is the A/C drain hose with part number A1678323600.  

Recall risks

Water entering the passenger compartment presents many risks to both the vehicle and the occupants. Rust could form from within the vehicle and the water can also potentially short out the electrical system. Apart from presenting an increased risk of fire, this can also cause the car’s electronic features to malfunction, which could affect the ability to unlock doors and call emergency services.

The leak can also accidentally trigger the engine’s limp-home feature while driving, upping the probability of a crash.       

Warning signs

Users may notice that the front footwell carpets have become wet under normal use, as well as misting on the windows.

Background of the recall

In August 2021, Mercedes-Benz conducted an investigation into reports that certain GLE and GLS vehicles that were not included in previous recalls were experiencing water leaks. By February 2023, the automaker traced the problem to drain hoses incorrectly installed during the assembly process. This led to the present recall. There has been no reported crashes or injuries leading up the the recall announcement.

Other Mercedes-Benz recalls

In October 2022, Mercedes-Benz recalled 59,574 vehicles due to faulty seat back locks on the third row seats that could potentially increase the risk of injury in a crash.    

In January 2023, some 123,696 Mercedes-Benz vehicles spanning multiple models were recalled following reports of detaching sunroofs, as reported.

The repair

Dealers will reinstall the hoses correctly free of charge.

Owners of affected vehicles will be notified by May 16, 2023.
