Complaints frequently mention the ease of accidental activation of cruise control at low speeds, leading to sudden acceleration, particularly in parking lots. Additionally, there are reports of the vehicle unexpectedly shifting into neutral or displaying messages to limit speed, often accompanied by hard brake pedals and reduced braking ability. These issues occur across various mileages, from as low as 30,000 miles. Safety implications include potential collisions due to loss of control or unintended acceleration, especially in congested or high-speed environments.

Owners of the 2023 GMC Yukon report issues related to the fuel/propulsion system, with complaints often mentioning engine sluggishness during acceleration and repeated fuel injector failures.
