In recent years, the Mercedes-Benz GLS has established itself as a luxurious, powerful, and technologically advanced SUV. However, a significant issue has come to light affecting certain 2020-2023 Mercedes-Benz GLS and GLE models, where a transmission control unit software defect can lead to unexpected engine stalling. If you’re an owner of a Mercedes GLS with Transmission Issues, you need to act now to ensure your safety and protect your rights. Call the Margarian Law Firm today for assistance in addressing this defect and holding Mercedes-Benz accountable.
The Problem: Transmission Control Unit Defect
Mercedes-Benz has issued a recall involving specific 2020–2023 GLE 450 and GLS 450 vehicles due to a transmission control unit software issue. Under certain driving conditions, this defect can cause the engine to stall, leading to a sudden loss of propulsion. This defect poses a serious risk to driver and passenger safety, especially in situations where engine stalling could result in a collision.
Important: Although the NHTSA only reports only the GLE 450 and GLS 450 models to have the issues, the Margarian Law Firm has identified numerous other models, such as the GLS600, to have the same defect.
The defect is linked to the vehicle’s transmission control unit (TCU). Mercedes-Benz has determined that the issue occurs when:
- The vehicle is decelerating slightly (e.g., when the driver applies light braking).
- There is an incomplete downshift from 7th to 6th gear.
- The transmission oil temperature is low.
- The vehicle’s 48V starter-alternator is actively recuperating energy.
When these factors combine, the engine may unexpectedly stall. While the vehicle’s steering and braking systems remain functional, the loss of propulsion dramatically increases the risk of a crash. Additionally, this issue may occur without warning, making it even more dangerous for drivers.
Affected Vehicles
The recall impacts certain Mercedes-Benz GLE and GLS vehicles manufactured between 2020 and 2023. The specific models include:
- Mercedes-Benz GLE 450
- Mercedes-Benz GLS 450
- Mercedes-Benz GLE/GLS 600 (based on reports and complaints from clients at the Margarian Law Firm)
Owners of these vehicles are urged to contact their local dealership immediately to verify whether their vehicle is part of the recall. Mercedes-Benz has indicated that the fix involves a software update to the transmission control unit, which is offered free of charge to affected owners.
The Impact on Owners
For owners of these affected vehicles, this transmission defect can lead to significant safety risks and inconvenience. Imagine driving on a busy freeway or navigating an intersection when the engine stalls – the consequences could be disastrous. Furthermore, the issue undermines the confidence and trust owners place in the Mercedes-Benz brand, which is known for its commitment to engineering excellence and reliability.
Beyond safety concerns, owners may experience additional challenges, such as:
- Reduced Resale Value: Vehicles with a known defect or history of recalls may lose value in the marketplace.
- Lost Time and Expenses: Trips to the dealership for diagnosis, software updates, and repairs can be time-consuming and disruptive.
- Ongoing Issues: Some owners report unresolved problems even after recall repairs, raising concerns about the long-term reliability of the vehicle.
What Is Mercedes-Benz Doing to Address the Problem?
Mercedes-Benz has acknowledged the issue and initiated a recall campaign to update the transmission control unit software in affected vehicles. The recall process includes:
- Notification to Owners: Mercedes-Benz is contacting affected owners via mail to inform them of the defect and the availability of a fix.
- Software Update: The repair involves updating the TCU software to correct the defect. This update is performed free of charge at authorized Mercedes-Benz dealerships.
- Follow-Up Testing: After the software update, dealers are expected to perform diagnostic checks to ensure the issue is resolved.
While this recall is a step in the right direction, Mercedes-Benz does not have a complete solution to the issue and many owners may feel that Mercedes-Benz’s response falls short of addressing the inconvenience, loss of trust, and potential dangers associated with the defect. This is where legal action can make a difference because many of our clients still have their vehicle kept by the authorized service departments due to the lack of proper and working remedy.

If you own or lease a Mercedes-Benz GLS or GLE affected by this defect, you may have legal options to pursue compensation. Under California’s Lemon Law and other consumer protection statutes, you could be entitled to:
