2016 GMC Yukon Power Train

The contact owns a 2016 GMC Yukon. The contact stated while driving 70 MPH, and attempting to accelerate, the vehicle jerked, then briefly lost motive power before the engine seized. The contact was able to coast to the side of the road. The transmission warning light was illuminated. The vehicle failed to restart. The vehicle was towed to a friend's residence. The vehicle was not diagnosed or repaired for the most recent failure. Days before the failure, the vehicle jerked while driving at various speeds. The vehicle was taken to Auto Zone; however, no cause for the failure was found. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 143,000.

TRANSMISSION SHUDDERS, LURCHES FORWARD UNCONTROLABLY, AND HARD SHIFTS

Without warning, giving vehicle low consistent pressure on gas pedal to move forward slowly (2-3mph) vehicle rpm jumped up then suddenly shifted and vehicle jerked forward in a school zone. Behavior continued and vehicle was ultimately towed.

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.

The contact owns a 2016 GMC Yukon. The contact stated while driving at various speeds, the vehicle was sputtering. The contact stated that the sound had increased over time. The contact took the vehicle to the dealer who stated that the transmission gear oil had failed and needed to be replaced. The vehicle had been repaired. The contact learned that the failure was related to NHTSA Campaign Number: 14V374000 (Power Train) however, the VIN was not included. The manufacturer was not made aware of the failure. The approximate failure mileage was 85,000.

Had transmission serviced at the dealer in May 2021. The RPM's are revving in first gear and my mechanic said I need to go back to dealer to have the transmission serviced again. There have been multiple reported problems with this transmission and a recall needs to be issued. The DT-45096 TransFLow Cooler Flush Machine and DT-52263 Transmission Fluid exchange kit with Mobil 1 fluid was requested at the May 2021 visit.

The contact's sister owns a 2016 GMC Yukon. The contact stated that while her husband was driving at an undisclosed speed, the vehicle lost motive power. The contact's husband was able to restart the vehicle; however, the vehicle was only able to reverse but not drive forward. The vehicle was towed to the contact's residence, where it was diagnosed by an independent mechanic with transmission failure. The vehicle was not repaired. The dealer was made aware of the failure but informed the contact that the warranty had expired. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.

Vehicle shudders, jerks excessively, and shifts erratically when accelerating. Had transmission serviced, fluid flushed, pan cleaned, transmission filter changed. Metal shavings were found in the pan and filter and covering magnet in pan. During flush metal shavings were recovered from oil cooler. Transmission continues to display same symptoms and rpms fluctuate during steady acceleration described as evidence of transmission slipping. Vehicle has not been serviced by dealer. No warning lamps or DTC indicated. Approximately 1500 miles after service during follow up inspection, metal shavings/debris were found in fluid on dipstick. All gm recommended parts and fluids used during service.

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.

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.

AFTER LEAVING THE DEALERSHIP WHEN GETTING THE BRAKE RECALL UPDATED WITHIN 48HRS MY TRANSMISSION STARTS SHUDDERING! NEVER HAD A SINGLE PROBLEM UNTIL THE RECALL WAS UPDATED! WAS TOLD THERE IS ONLY A FLUID FLUSHING AVAILABLE FOR THE 8CYL TRANSMISSION NOT THE 6CYL! WAS TOLD THAT I WAS OUT OF MY POWER TRAIN AT 82K MILES AND I WOULD HAVE TO PAY OUT OF POCKET TO FIX THE TOURQUE CONVERTER OR BY A NEW TRANSMISSION! PLUS WAS TOLD THERE IS NOTHING THEY CAN DO TILL AFTER JANUARY 2020 BECAUSE THEY ARE BACKED UP FROM OTHER VEHICLES HAVING THE SAME ISSUES! THERE IS A CLASS ACTION LAWSUIT FOR THE 8CYL BUT NOTHING FOR THE 6! WHY? I LOVE MY CAR AND YOU WOULD THINK AT 70K IT WOULD BE MORE RELIABLE AND GM WOULD BACK THEIR PRODUCT! I'M VERY DISAPPOINTED WITH THE MAKERS OF GM AND WITH THE ISSUES I'M LOOKING AT WITH NO RELIEF IN SIGHT I WOULD BE BETTER OFF TRADING FOR A FORD OR ANYTHING OTHER THAN GM! I'M REALLY HOPING THAT IS NOT THE CASE AND GM WILL OFFER A FIX FOR THESE ISSUES!
