  • 2021 Mercedes-Benz AMG GLE53

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.

Mercedes-Benz recalls SUVs over seat lock issue, injury risk

Jacksonville, FL – October 28, 2022 – Mercedes-Benz (OTCMKTS:MBGYY) is issuing a recall for 59,574 SUVs over faulty locks on the third-row seat backs, which could lead to injury in the event of a crash. 

The recall covers the following models: 

  • 2021 Mercedes-Benz AMG GLS63
  • 2020 – 2022 Mercedes-Benz GLS 450
  • 2020 – 2022 Mercedes-Benz GLS 580

Recall summary

Seat back locks secure seat backs in place and prevent them from unintentionally moving forward when an accident occurs. In the affected models, locks on the third-row seats could fail when the vehicle is involved in a crash due to a supplier error.

The component involved in this recall is the seat backrest frame located in the Mercedes-Benz third row seats, with part numbers A1679301702 and A1679301802. 

Recall risks

When a crash happens, a defective seat lock could cause the seat back to forcefully fold forward, increasing the occupant’s risk of injury. 

Other Mercedes-Benz AMG recalls

In May 2022, Mercedes-Benz issued a recall for 21,306 mild-hybrid vehicles over a loose electrical connection under the front passenger seat, which presents a higher risk of overheating and fire.

In July 2022, the automaker issued another recall for 8,530 cars over a software issue on the rearview camera that could prevent it from displaying an image on the dashboard monitor. This reduces the driver’s view of the area behind the vehicle, increasing the risk of an accident.

The repair

Owners can bring affected vehicles to an authorized Mercedes-Benz dealer, who will check the third-row seat back locking mechanisms and, if necessary, replace the seat back. This will be done at no cost to the owner.

 Affected owners will be notified on or around November 29, 2022.
