I am filing a complaint regarding a serious safety issue with my 2017 GMC Yukon XL related to the brake vacuum pump. According to recall information (the federal safety agency Recall ID: N192268490), certain 2015-2017 GMC Yukon and Yukon XL vehicles are equipped with a defective vacuum pump that may decrease in output over time. This defect reduces power brake assist, resulting in increased braking effort, a hard brake pedal, and extended stopping distances. These conditions significantly increase the risk of a crash. I have experienced symptoms consistent with this issue, including vibrating brake pedal with no slippage, a hard pedal, ticking noises from the engine, a 'Service Brake Assist' warning message, and difficulty braking. This issues usually occur under 10 mph. These problems compromise the vehicle’s braking performance and pose a direct threat to the safety of myself, my passengers, and other road users.
