Brake lights & torque converter 2016 Yukon denali. The brake light is out on the passenger side. I brought it to the dealership, and it is within 2 weeks of the warranty expiring. They had to order the part because there's a national backorder for the assembly. So clearly I'm not the only one. Did some research and this is apparently an ongoing problem. This vehicle has been a hassle from the start. I'm beginning to believe there is an electrical issue as well. I had a battery issue that the dealership couldn't figure out even after showing them the onstar alert. Originally I was told onstar was probably just sending it as a mileage alert. Turns out after I insisted they put the vehicle on a machine and it showed the battery was indeed faulty. Multiple things have gone out on a vehicle with barely 30,000 miles on it. The torque converter is also a major concern because it 'shed' metal pieces with the car having less than 20,000 miles they only drained the transmission fluid because that's what the bulletin told them to do. How is this not going to happen again? my Yukon drove like a lawnmower vibrating and hopping. This is the worst vehicle I've ever purchased, and with the issues that keep piling up it looks like we aren't anywhere near the bottom of the problems.

When in traffic at slow speeds the brake system shuts down and takes my body weight to stop car. Had checked and no visible leak. Now GMC has a fix but charge to fix if over warranty mileage. Second issue is the transmission went at 96,000 miles while highway driving loosing all top end gears at 65 mph. GMC did nothing but dealer helped on tho as well

The contact owns a 2016 GMC Yukon. While the vehicle was accelerating from a stop, the transmission shuddered and failed to respond appropriately. The RPM gauge was erratic and flashed. The vehicle was towed to marvin K. brown auto center (1441 camino del rio South, auto cir, san diego, ca 92108) where it was determined that a power train warranty provision was not an available option and the manufacturer had not issued a power train recall. The dealer diagnosed that the transmission needed to be replaced. The vehicle remained at the dealer and had not been repaired. The manufacturer was notified of the failure. The VIN was not available. The approximate failure mileage was 130,268.

The vehicle's transmission unexpectedly slips out of gear between 20 and 35 mph. When this occurs, pressing the accelerator merely revs the engine, without forward motion. This occurred 4 times in the first 600 miles of operation. Without power, I can't navigate out of a dangerous situation.
