I am filing this complaint regarding a serious and ongoing safety issue with my GMC Yukon denali that began with a complete engine failure while driving on the highway with my entire family in the vehicle. While driving at highway speed (about 60–70 mph), the vehicle suddenly lost power and shifted into neutral on its own. While still moving, I tried multiple times to shift back into drive so I could safely get off the road, but it would not engage. I was only able to coast partially onto the shoulder before the vehicle came to a complete stop, still partly exposed to traffic. The engine shut off and would not restart at all. It would not go into drive or neutral, and the vehicle was completely dead. And it had to be towed. The dealer later told me the engine had failed and that a new engine was installed. About a week later, I picked the vehicle up. Less than 20 minutes after leaving the dealership and getting back on the highway, smoke started coming from the vehicle and warnings appeared, messages that the engine was overheating and that I needed to stop the engine immediately. The vehicle was not drivable again and had to be towed back. I again had to arrange transportation home. A few days later, I picked the vehicle up again. Since then, I have had serious four-wheel-drive and drivetrain issues. The vehicle became stuck in 4 low and I could not get it out for over a day. When it finally came out, the drive mode buttons stopped working correctly. Selecting 2 high sometimes puts it into 4 high, selecting auto puts it into 2 high, and auto mode no longer appears. Even when it shows 4 high, the steering is restricted cannot steer 100% to the right or left and the vehicle binds, pops, and jumps when turning. I believe this vehicle is unsafe and poses a serious risk.
