Mercedes-Benz recalls SUVs for electrical short

Jacksonville, FL – May 6, 2021 – Daimler AG (NASDAQ:DDAIF), which owns the Mercedes-Benz brand has recalled 6,331 SUVs that may experience an electrical short due to a water leak. The recall includes:

  • 2021 Mercedes Benz AMG GLE 53
  • 2020 Mercedes Benz GLE350
  • 2020 Mercedes Benz GLE450
  • 2020 Mercedes Benz GLE580
  • 2020 Mercedes Benz GLS450
  • 2020 Mercedes Benz GLS580

Recall summary  

The recall centers around an issue with the air conditioning drain hose, which may be installed incorrectly. Just like how water beads up on the outside of a glass of ice water, cool air from air conditioning causes water to condense into droplets inside the air conditioner. This water has to drip somewhere, and the drain hose is supposed to move that moisture out of the car, away from sensitive wiring and electronics.

In the recalled vehicles, the incorrectly installed drain hoses may cause water to leak down into the floor of the car. The electrical wiring there is not waterproof, and the water could cause an electrical short, creating the risk of a fire. 

Previous recalls

This recall builds on two previous ones by Mercedes Benz, who recalled 18,392 vehicles in 2019 and 3,615 in 2020 for the same issue in other models. Mercedes blames the loosely connected drain hoses on a “deviation in the assembly process” during manufacturing.

Warning signs

If the air conditioner drain hose is leaking,  drivers and passengers may notice the carpet under their feet is wet, or that the windows are fogged up.


This water leak poses several risks. The various electronics that may be damaged by the water can disable features related to safety, like the emergency call system that alerts first responders if a crash is detected, and the door locks (which may hinder first responders from opening the doors in an emergency). If the vehicle is suddenly forced into a decreased power mode, the car may slow unexpectedly, creating the risk of a crash. 

Lastly, the risk of fire is serious, and puts passengers at risk of inhaling toxic fumes, getting burned or dying. Read more about the risks of an interior car fire in this article about a recent Hyundai recall over fires caused by the 12-volt “cigarette lighter” outlet.

The repair

Mercedes Benz dealers will check the air conditioner drain hose and make sure it is installed properly, free of charge. Owners will be notified about the recall with more information about when and how to seek repairs starting June 22.

Volkswagen recalls Audis for broken suspensions

Auburn Hills, MI – May 5, 2021 – Volkswagen  (OTCMKTS:VWAGY) – which owns the Audi brand – has recalled 40,993 Audis, including a number of 2021 Audi SUVs, because a part of the suspension may break. The recall includes:

  • 2020 – 2021 Audi A4
  • 2019 – 2021 Audi A5
  • 2020 – 2021 Audi A6
  • 2020 – 2021 Audi A7
  • 2020 – 2021 Audi A8
  • 2020 – 2021 Audi Q5
  • 2020 – 2021 Audi S4
  • 2019 – 2021 Audi S5
  • 2020 – 2021 Audi S6
  • 2020 – 2021 Audi S7
  • 2020 – 2021 Audi S8
  • 2020 – 2021 Audi SQ5
  • 2020 – 2021 Audi S5 Cabriolet
  • 2021 Audi Q7
  • 2021 Audi Q8
  • 2021 Audi RS Q8
  • 2019 – 2021 Audi RS5
  • 2021 Audi RS6 Avant
  • 2021 Audi RS7

The component name is ”Lock nut M14x1,5,” part number WHT 007 610.

Recall summary  

The recall stems from an issue with a single nut in the car’s trailing arm suspension. The trailing arms is a type of suspension that helps keep the rear wheels aligned properly. 

Due to a supplier error, the nuts used to connect the trailing arm to the rest of the car were not manufactured “according to specification.” As a result, certain batches of nuts may get corroded or damaged, causing them to break.


When the nut holding the trailing arm breaks, the rear wheels could become misaligned, changing the direction the car is moving in. “It cannot be completely ruled out that [the car] could suddenly and uncontrollably move in the wrong direction at higher speeds,” Volkswagen says in recall documents. If this occurs, the driver can lose control and crash.

Warning signs

Drivers with a broken trailing arm nut may notice the steering wheel is not aligned when they are driving or that the vehicle lists to one side when they hit the gas or brake. Volkswagen knows of two incidents of this kind; both took place outside the US.

Other Audi recalls

Volkswagen recently recalled over 150,000 Audi A3-generation cars for faulty airbags. These passenger-side airbags are prone to deactivating while someone is sitting in the seat, upping that passenger’s risk of injury in a crash. 

The repair

Volkswagen and Audi dealers will replace the defective nut and will check for existing damage. If the part is already damaged, the whole screw connection will be replaced. Both services are provided for free. The repair is not yet available, but owners will receive more information about the recall by June 25.

Kia recalls SUVs over stall and fire risk

Irvine, CA – May 4, 2021 – Kia Motors (OTCMKTS:KIMTF) is recalling 147,249 vehicles equipped with 2.0L Nu MPI engines, which may stall or catch fire while driving as a result of internal damage. This increases risk of a crash and may result in serious injuries to vehicle occupants.  This Kia vehicle recall includes the following vehicles:

  • 2021 Kia  Seltos
  • 2020 Kia Soul 
  • 2021 Kia Soul

The component in question is called “piston assembly,” part number 23041-2E801. This is the latest in the series of ongoing fire-related Kia and Hyundai recalls.

Recall summary  

The engines of these cars contain piston oil rings, whose function is to seal the combustion chamber  – where gasoline and air mix  – from other parts of the engine, partly to ensure that no extra oil is passed into the chamber.

Due to a supplier error,  the recalled vehicles’ piston oil rings were “improperly heated” during production.  As a result of this, they may become excessively hard to the point where they start chipping. This may result in the seal between the other parts of the engine and the combustion chamber breaking, which may cause extra oil to get into the engine and damage it.

The damage may cause the car to stall while driving. If the car continues to be driven, parts of the piston assembly can break apart and pierce the engine. This may result in the vehicle catching fire as oil escaping from the engine comes in contact with the “hot exhaust components.

Warning signs

The driver may be alerted to this problem if they hear the engine make a metallic rattling sound and feel it vibrate. In most cases, this will be accompanied by an illuminated “ oil pressure warning light” on the dashboard. To prevent any further damage, the driver should stop the vehicle in the first safe spot and turn off the engine. 


Stalling while driving may lead to potentially dangerous situations, especially if it happens in high-speed or dense traffic. Car fires are very dangerous and kill over 300 people a year on average,  as reported.

For tips on what to do if your car catches fire, please see this article about last year’s Kia Stinger recall for mystery fire risk.

Other Kia engine recalls

Both Kia and Hyundai have been subject to multiple fire-related recalls. Recently, the latter – which is part-owned by Hyundai and builds vehicles on its platform – recalled over 300,000 Kia Cadenza and Kia Sportage cars because of fire risk related to a part within the anti-lock brake system (ABS). Faulty engine rod bearings were the culprit behind a recent Hyundai recall due to the stall and fire risk.

Seltos Kia 2021 is not subject to any additional recalls.

The repair

To fix the issue, Kia Motors dealers will conduct a special engine examination in affected vehicles . If an oil ring flaw is found, the dealer will replace the whole engine. In certain cases, the dealer might also install software that will alert the driver that the piston oil ring is damaged.

The recall is slated to begin on June 11.
