Automatic Transmission Torque Converter problems of the 2016 GMC Yukon

While driving my children to practice my vehicle jerked us forward in a violent motion as if another car hit us and there was no one on the road. Afterwards the car slowed to about 5-20miles an hour and would not drive any faster. I stopped at the nearest intersection and the car would not move. I turned off the ignition and turned on again and was able to get out of the road to safety. This is a serious issue and I have already been to the mechanic to have the torque converter replaced. I have complained several times to no avail about this issue.

Faulty torque converter.

Vehicle began to shudder and jerk upon acceleration at 30k. Dealership changed fluid. At 60k vehicle continued to shudder and jerk upon acceleration and lurch forward or backward although brake was depressed. Initial, brief diagnoses reveals a bad torque converter. This issue was noted in 4 TSB. TSB id #pip5337k, TSB id #pip5337f, TSB id #16-na-014, and TSB id #pip5337h. Now that my factory warranty has expired, gm maintains no responsibility for this problem-- although they saw it while covered under factory warranty for this same issue. Additionally, there is a current class action law suit with gm regarding this issue. The shuddering, shaking, jerking and hesitation is related to internal issues within the transmission and/or torque converter causing friction surfaces, hydraulic systems, and gears to not function properly, and resulting in metal shavings being circulated throughout the transmission. Over time, damage to the transmission and torque converter occurs. Consumers face escalating repairs that can include flushing the transmission of metal shavings caused by the defective transmission operation, and which eventually necessitate the replacement of components such as the torque converter, valve body, or the entire transmission. As such, the transmission defect endangers the drivers and passengers of the vehicles, and diminishes the value of the vehicles. Furthermore, the dealership acknowledges that metal shavings due to friciton could have passed through the system causing further damage but will not remove the transmission for full and throrough diagnoses.

We were on our way back from pittsburg, PA to maryland and the transmission started slipping when we stopped in kent island at chick fil a. The vehicle stopped moving completely and would not move forward as we were turning into the drive thru. We had to have the vehicle towed to a GMC dealership in easton, MD. Upon their evaluation of the vehicle, we were told that the torque converter came apart and damaged the transmission. When I asked how and why the torque converter came apart, they stated that they would have to take the entire engine apart to figure that out. We were told by the GMC dealership that our 2016 GMC Yukon xl now needed a new transmission. We purchased this vehicle in December 2015 (brand new). Because our power train warranty expired at 60,000 miles, it was not covered. The new transmission costs us $5300+. We were shocked that this took place, as this was purchased new and we have kept up on all the maintenance. It is very disturbing to have purchased a new transmission for a vehicle that is only 4 years old. In doing some research, this seems to be an ongoing issue for GMC. A recall should be issued and a refund should be issued to those who have paid out of pocket for this expense. I do thank the GMC dealership in easton, MD for quickly repairing our vehicle, especially since we had an upcoming trip. Ladonna was wonderful and I commend her and the entire dealership for handling things swiftly.

Dealership refuses to provide documents until I pay for repairs. Original estimate cost of $5634. 00 now escaleted to 6300. 00 for a repalcement part that cost approx $500. Unethical, predatory, unfair.

Instructed GMC dealer to perform 90,000 mile transmission maintenance (as per GMC manual: "change automatic transmission fluid, if equipped. If filter is serviceable, change filter"). GMC dealer decided to perform transmission flush instead which does not include a filter change. Within short period of time, transmission started to shudder when in 3rd and 4th gear. Dealer insists this has nothing to do with service they performed and told me there is a known problem with the torque converters. Dealer stated on the phone "we do 2 or 3 of these a week. . . Often on vehicles with only 20,000 miles". A quick search on the web for gm 6l80 transmission problems will show all of the owners with similar torque converter issues. Dealer gave rough estimate of $1700 to replace torque converter.

Vehicle shudders when shifting in lower gears. Possible torque converter or other transmission problem.

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.

I have only owned this car since 3/29/19 and several times now my Yukon's check engine light has came on after the transmission bucks, jumps or jerks hard, not sure what to call it but it bucked or shoved my car forward when trying to slow down or stop (not pressing gas pedal). This could be dangerous as it interferes with trying to stop the vehicle. It was such a hard jolt that it for a minute I thought another car rear ended me. This has happened at least twice after I pressed the brake to begin slowing down as I was preparing to pull into a parking lot, I was probably going around 20mph. It also happened twice while accelerating onto a road, probably going 35 mph and just felt a jolt like something kicked my car forward suddenly. I've been told that the jerking problem is related to issues with the transmission, possibly the torque converter and causes gears not to function properly. I'm going to put in my most recent date that this happened on your form but it's happened more than once.

Tl-the contact owns a 2016 GMC Yukon denali. The contact stated while driving at low or high speeds, the vehicle would violently shake, feeling like it was going to fall apart. The check engine warning light illuminated. The vehicle was taken to cappellino Buick GMC (5411 transit rd, buffalo, NY 14221) where it was diagnosed with a tcc (torque converter) shudder failure and a transmission flush was completed.

The contact stated that the vehicle was currently at west herr as the vehicle was stalling. The rpm's increased and the vehicle . The traction and check engine warning lights illuminated.

At 76,000 miles the transmission began to shudder violently and hestitate. Dealership GMC wants me to spend 400 on a fluid upgrade and hope it fixes it if not, I will have to buy a new updated torque converter because they shrewdly took the drivetrain warranty down to 60000 miles months before I bought new.

I have had issues with the transmission and power of the car for over two years. I have contacted GMC and have followed everything that GMC have requested for me to do with a vehicle. I have taken the car to four different dealerships, have had everything done with it from flushing it three to four times and have had torque converter replaced the control valve body replace. Recall for the brake pedal was also done. After everything the car is in worst condition at the moment.

Electrical issues: while driving the information panel go's blank. We have experienced this twice while driving, we lose the speedometer, tech, and everything on the display panel. Radio, skips channels even after the switch was replaced. Drive train: down shifts abruptly while accelerating onto interstate on ramps, either lunging forward or lunging backward. Been in the gm shop three time to try and fix issue. There have been bulletins issued to try and fix without success to-date. They are aware that is a problem, because Ford and gm on the 2018's, I was told by the sales persons that this issue was fixed. I am aware of the chevy transmission issue and I am concerned that this maybe a similar safety concern. As far as I know the transmission has not jumped out of gear on its own. I am looking at a shop ticket and they are calling the issue a shutter during torque converter locks up.
