Over the past 14 months, the emergency breaking system has gone off approximately 25 times during non-emergency situations. Most of the incidents have been when no other vehicles or impediments are anywhere close by. This has created a very significantly unsafe and ongoing situation for my family which so far are being ignored by Mercedes Benz.

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 all-wheel drive system, which did not appear to effectively intervene. The vehicle spun and was involved in a crash, placing myself, my wife, and my child—who has Autism—at significant risk, along with surrounding motorists traveling at interstate speeds. Despite visible tread remaining, the tires did not perform as expected. Based on warranty expectations of approximately 50,000 miles, the apparent performance failure at only 15,257 miles raises serious safety concerns. The vehicle is currently at a collision repair facility and is available for inspection. The issue has not been reproduced, and a manufacturer inspection is pending. The vehicle has been inspected by law enforcement and insurance representatives. There were no warning lights or alerts related to traction, stability, or tire performance prior to the incident. As a result, the vehicle was rendered undrivable, required towing, and has been under repair for over a month, causing significant inconvenience and financial impact. I am requesting a formal investigation and review for appropriate resolution.
