2024 MERCEDES-BENZ Gls 450 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 the scene. It is currently located at a collision repair facility and is available for inspection upon request. The suspected systems involved include the Electronic Stability Program (ESP), traction control system (TCS), 4MATIC all-wheel drive system, and Supplemental Restraint System (SRS/airbags). The vehicle has not yet undergone a full manufacturer engineering inspection, but such a review has been requested. The loss of traction at interstate speed in wet conditions created a serious safety risk to the occupants of the vehicle and surrounding motorists. The apparent lack of stability control intervention and the absence of airbag deployment increased the potential risk of injury. The vehicle was inspected by law enforcement at the scene, towed, and has been reviewed by insurance representatives as part of a claim. A manufacturer inspection is pending based on a defective claim that was filed. There were no warning lights, alerts, or messages related to traction control, stability control, or airbags prior to the incident.
