Transmission went out very early. Had to get it replaced whenever I reverse. I have to really smash on the break in order for it to stop if it does stop so somethings wrong with the breaking whenever I hit a bump the left side suspension feels like I’m a lose control and sometimes my radio works and sometimes it doesn’t I’ve been trying to work with dealers I have extended warranty on it. They’re saying it’s not covered something about the brake pump is covered, but the belts are not. The transmission was put in only because it left me stranded. Otherwise I would’ve been stuck paying for that. The dealership actually helped me with that. My GPS turns on and off sometime. I’m not sure if it’s electrical

Transmission failure, hard shifting, slipping and loss of power also severe shuddering. Very dangerous driving. I had to have the transmission replaced after taking the vehicle to a dealership and upon verification from same dealership reproducing the transmission failure. Massive financial loss, dealership stated these transmissions are known to fail. Manufacturer has been notified by numerous complaints. Compensation is warranted

While taking my children to school, the vehicles RPMs began to jump, causing the vehicle to lose power. Which resulted in myself and two children stranded on the side of the road. The vehicle had just crossed over 110,000 miles when the transmission completely broke apart from the inside. There was no other warnings or lights that appeared on the dash prior to or after. We had been given an estimate from GM for $6200 for a new transmission.. but that was extremely difficult to afford. We ultimately had to have the transmission rebuilt due to it costing $3,000 less, so we could continue going to work. We are still having issues with the transmission even after taking to back for a 2nd time to be reprogrammed. It’s extremely frustrating to have paid so much for this Yukon to have transmission go out with as many miles as it did, plus with no warnings.

The transmission malfunctions, shifting is inconsistent and shifts by itself. Shudders and causes the engine to increase and decrease in RPMS. This causes the engine to lose power. The truck will slow because of bad shifting and stall. The dealer did a diagnostic test and verified the transmission problem. The vehicle was inspected by the vehicle brand dealership. There were no warning lights or any other signs of the transmission failure.

Transmission failure at 90,000 miles

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.

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.

In my experience of transmission failure with my 16’ GMC YUKON, there was no warning. I had not experienced any issues with the slipping or jerking feel when accelerating or braking as described in the class action law suit. My vehicle had 105k miles, I took it in for regular maintenance including having the transmission flushed as I was told to do so for preventative maintenance. The transmission failed when I was traveling on the interstate with my family and I came upon some traffic so I applied the brake and the whole vehicle bucked and jerked as it shifted into down gear. I was traveling at 30-35 mph in the traffic and the whole time I felt a slipping motion in the car. I made it to a gas station, refueled, and tried to restart my journey. As I leery the gas station accelerating to get back on the interstate, the vehicle would not accelerate above 35 mph and the RPMs we’re to the max. At this point, my vehicle was in drivable. No prior warning, no issues that had been occurring over time, this all happened the same day. I towed my vehicle to a Chevrolet dealer where the problem was identified as a failed transmission in need of replacement and failed ABS braking system. The cost came at $6800.
