I am submitting a complaint regarding the air conditioning system in my vehicle. The vehicle has a refrigerant (Freon) leak that causes the air conditioning system to stop cooling properly. In addition, there is a loud abnormal noise coming from the AC system while operating. The issue has progressively become worse. The air conditioner either blows warm air or loses cooling performance completely, especially during normal driving conditions. The abnormal noise appears when the AC compressor engages. This defect affects driving comfort and may indicate a failure of the air conditioning components, refrigerant lines, or compressor system. The refrigerant leak also raises concerns about…

The panoramic sunroof spontaneously shattered. I was driving on highway under open sky and the sun roof just imploded and all the glass came shattering inside all over. There were no extreme weather or any construction or chances of any debris from anything around. No impact object could be identified upon inspection after the car was stopped.
- TiresCrash
On November 30, 2024, I purchased a new 2024 Mercedes-Benz GLS 450 4MATIC equipped with factory-installed Pirelli tires (size: P 275/45HR21 front; 315/40HR21 rear). At the time of the accident on February 22, 2026, the vehicle had only 15,257 miles. While driving on the interstate in wet conditions, the tires failed to provide adequate traction, causing the vehicle to hydroplane. The loss of traction felt as though the vehicle was driving on ice and was inconsistent with over a year of prior operation in similar weather conditions without issue. The suspected components involved include the Pirelli tires, as well as the Electronic Stability Program (ESP), traction control system, and 4MATIC…

During interstate travel in rainy conditions, the vehicle appeared to lose traction and hydroplane. The tires appeared to have adequate remaining tread; however, they did not provide expected traction and the vehicle felt as though it was driving on ice. This was inconsistent with my prior experience operating the vehicle for over a year in various weather conditions without encountering similar issues. The Electronic Stability Program (ESP), traction control system, and 4MATIC all-wheel drive system did not appear to intervene to stabilize the vehicle. The vehicle spun and was involved in a crash. Despite the impact, no airbags deployed. The vehicle was rendered undrivable and towed from…
- Forward collision avoidance › Automatic emergency brakingCrash
The 2024 Mercedes-Benz GLS 450 exhibits a critical "Spatial Mapping Offset" defect within the MBUX 360-degree camera interface and the Active Brake Assist (ABA) logic. Specifically, the digital rendering of physical obstacles on the dashboard display is offset by approximately 0.5 feet (6 inches). This creates a "false clear" condition where the driver is visually signaled that an obstacle has been cleared while the vehicleâs chassis is still in a strike position. On September 27, 2025, this defect resulted in a collision with a stationary post. Despite the systemâs Parking Control Module identifying the object (recorded as "Orange/Indented" in dealer Repair Order #731706), the system…
