The contact owns a 2016 GMC Yukon XL. The contact stated that on numerous occasions while driving at various speeds, the vehicle hesitated and jerked. The contact stated that the vehicle lunged forward. There was no warning light illuminated. The vehicle was taken to the dealer several times and diagnosed that there was a defect with the transmission. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 134,000.

On December 6, 2022, while I was driving on a busy highway, my 2016 GMC Yukon jumped out of gear and slowed down until it was at a dead stop. I managed to pull over on the shoulder, but not before I came extremely close to another car running to the side of the vehicle at an intersection. Luckily the other driver had good breaks! Once I passed this busy intersection, I inched it very slowly to the shoulder. Luckly the road was on a decline and not an incline. I called a tow truck to tow the vehicle to a certified GM mechanic. The shop verified that the transmission went out. The mechanic stated that there was really nothing I could have done to prevent it without some type of warning. The vehicle only had 81,000 miles at the time and there were no warning lights blinking or signs that it was about to go out. Only sign was that morning while driving to work there was a hard shift between 2nd and 3rd gear but it wasn’t long after that the transmission went out. I had a new transmission installed on 12/09/2022.

Engine lifter failure causing complete engine failure at 70,000 miles without any warning. All vehicle maintenance done and serviced at dealer 30 days prior. Left our family stranded on a busy 2 lane highway and were lucky to even get off the road.

Without warning my 2016 Yukon Denali jerked so forcefully into drive it felt like we were hit from behind. It went into gear and sped into intersection and stalled. We were almost hit. This is a huge problem with2016 GMC's and they are aware of it. It is the 8 speed transmissions that are causing this. They refuse to help get it fixed. I think they should be forced to! I will be out thousands if I can even find a shop that can get that transmission., They are back ordered because so many failures.

The contact’s wife owns a 2016 Yukon. The contact stated that while his wife was driving at approximately 5 MPH, the engine hesitated and stalled. The contact stated that his wife was able to coast the vehicle into a driveway. The check engine warning light was illuminated. The vehicle was towed to the dealer where it was diagnosed that a lifter in the engine block was damaged and the number two cylinder had failed, and the engine needed to be replaced. The vehicle was not repaired. The dealer was notified of the failure and the contact scheduled an appointment. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 102,000.

I currently have 109024 miles on my yukon. At the time the issue first occurred, it had 108998 miles. Up til that moment, it was running perfectly. About 5 miles into my drive on 11/13/2022 it started to shutter at the top of 2nd gear, then a hard shift into 3rd. The shutter repeated at the top of 3rd, before a hard shift into 4th gear. I turned around & returned home. Checked the fluids, everything was fine. Let it sit, had to drive it to work (6 miles or so) on 11/14/22 & it shuttered at the top of 2nd & 3rd gear again. Took it to Wallingford Buick GMC (in CT) Tuesday 11/15/22. Upon inspection, it was confirmed the transmission failed. $6538.31 for a new, replacement transmission. It's still at the shop, waiting for the new transmission to be delivered. I've maintained my vehicle, have regular oil changes & inspections of the powertrain components. This came totally out of the blue. No warnings, or any indication of pending doom.

We first noticed the vehicle's lack of power and sudden increase when driving at a stop light/sign. We checked and REPLACED spark plugs, cables, coils, and a new battery. We became highly concerned when the vehicle would accelerate while driving and the RPMs would toggle between 500-1500 RPMS without pressing the gas. We immediately took it to an authorized mechanic, who found excessive noise from the transmission area and found debris/metal. No codes were present when a system performance was done. The vehicle only has 68806 miles on the odometer. The transmission had to be fully replaced, which cost over $7k. The replacement was done. This seems to be a common issue (Transmission replacements) with this vehicle as now we're hearing more about it. PLEASE check this as we could have easily been in an accident from the loss or increase of power without notice and NO WARNING lamp indications. This was a very expensive repair caused by the manufacture and not user error. We paid a lot for this particular vehicle and certainly love it but am concerned about this expensive safety/mechanical issue.

At 90500 miles my Yukon xl started shuddering and the transmission started failing and I have never used it to pull anything so this was very dissatisfying for a 75k vehicle

The contact owns a 2016 GMC Yukon. The contact stated while driving approximately 30 MPH, the vehicle began to shudder and she noticed that the park assists, stabilitrak, and check engine warning lights were illuminated. The contact stated that the vehicle then stalled. The contact was able to shift the vehicle to park and restarted the vehicle. Additionally, the contact stated that after the vehicle stalled, the vehicle lost power steering functionality. The contact stated that the failure was intermittent at first but had become constant. Additionally, the air bag warning light and an audible chime would sound when the engine stalled. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the failure could not be duplicated. The vehicle was not repaired. The contact stated that the failure had recurred. The manufacturer had not been informed of the failure. The failure mileage was approximately 90,000.

The taillights, which included both the brake lights and running lights, quit working or only worked intermittently. Safety was put at risk because anytime we drove the vehicle in the dark (which is often!) the rear of the vehicle could not be seen, and the brake lights would not be activated when braking would occur, either day or night. This made us more likely to be in an accident, in my opinion, though thankfully we were not. Our regular mechanic did confirm that the lights were only working only intermittently, thought he did not have a solution but for replacing them, which would cost $800 a piece. There was no warning for this problem, the issue first appeared a year ago and we've been dealing with it since. I was finally able to purchase remanufactured taillights.
