What owners say
Engine check light on, Code P0302 cylinder 2 misfire. loud mortar ticking, car makes abrupt jump/move forward.
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.
The engine developed a ticking noise which turned out to be bad lifters and bent lifter rods, and a bad valve lifter oil manifold.

The contact attempted to depress the accelerator pedal however, the vehicle failed to respond as needed. The contact stated that a dealer and an independent mechanic were contacted. The vehicle was towed to an independent mechanic where it was diagnosed and determined that the camshaft was not aligned. The contact was informed that the independent mechanic would be able to align the camshaft; however, if the failure persisted there would be a cost for the repair. The vehicle was not repaired. The manufacturer was not notified of the failure. The contact related the failure to N232430470 - Special Coverage (Camshaft Position Actuator Valve Solenoid - Bank 2 (Left Side) Exhaust); however, the VIN was not included in the special coverage program. The approximate failure mileage was 131,000.
