  We just purchased our Yukon from a dealership in February (2/7/26) and it was diagnosed with premature failure of at least one AFM valve lifter as it is causing engine misfires, shaking and stalling on 7/30/26. We just hit 67,000 miles on the odometer so we are just beyond the warranty coverage. The lifters were replaced previously by the previous owners on 12/16/24.

  Issue with the trailer brake system keeps coming up on my dash. I know a lot of other people have had the same issue keeps dinging will not stop causes me to get distracted while driving. Unable to use other features because of this distraction and safety issue. The safety issue needs to be fixed this is an effective product with so many people having an issue you need to do a recall. I did let Graff Chevrolet in Mount Pleasant Michigan no and I took a picture and showed them.

• UNKNOWN OR OTHER

  My vehicle torque converter repair on my 2020 GMC Yukon is shuddering. Why is this not a recall when there are various Yukons that are experiencing shuddering related to torque converter repair. This should be a recall. The problem has been confirmed by a GMC dealer. There were not warning lamps, no messages, or other symptoms.

• ENGINE

  I took my vehicle to a dealer to repair something unrelated to the engine. They said the oil pan was leaking and pulled the pan to discover the crank shaft bearings were failing. The vehicle has 53,765 miles at this point. This appears to be the same defect being recalled on the 2022 through 2024 models.

• POWER TRAIN

  Severe transmission shuttering destroyed my transmission and I need a new one according to a local body shop and a GMC service center. This is a KNOWN issue with these 10 speed transmissions, but they will not recall the ones from this year, they only recalled newer models. Car has been inspected by a local autobody shop, a 3rd party warranty company, and a GMC dealership service center. Shuddering causes severe shaking while driving between 25-65mph. No lights or other symptoms, just started occurring randomly. Purchased car Feb 2025, brought it in to local auto shop November 2025 and they could not get a transmission for months. They stated one was set to be delivered by GMC Feb 6th 2026 and they day before arrival GMC called them saying it was back on back order. Called the dealership in April 2026 and they stated they were not backordered. Had vehicle transferred to dealership service center and they say it’s still on national back order with no ETA. I have been waiting for over 6 MONTHS for a new transmission. This car has been undrivable for almost longer than I have been actually able to drive it.

• POWER TRAIN,ENGINE

  The 2020 Yukon started to have serious loss of speed and decelerating issue when the vehicle would slow down and down shift to a lower gear. The issue with this is that once it downshifted it woul not engage in a gear again and leave me stranded on the road. I had to turn off the car and restart it for it to reengage in a gear enough to get it moving again and sometimes I had to try more than once to get it moving once it no longer wanted to engage in a gear. So in the 10 mile drive, I was left stranded at least 15 times. Each time I had to restart and restart again for the vehicle to engage in a lower gear. Once moving, it would sometimes it would engage in a higher gear and sometimes it would not. Thank goodness I wasn't traveling on the highway when this happened. Beware to anyone if this was to happen on the highway while in the middle lane while in traffic. And the check engine light never turned on and thus no code to help detect the issue. Took it the day before to have it looked at and was told nothing was wrong with it since there was a code and they could not duplicate the issue I described. WHAT?? They reset some transmission computer setting but it only made it worse by the next day. Now this 6 yr on 2020 GM Yukon is at the dealership service department requiring a new transmission for 7200. Said that the transmission fluid was showing particles of stuff and color was 'burnt', I think. Transmission fluid was changed at it's regular check up time so that didn't cause the issue and nor should it have bits and pieces in it and discolored. Is there any recourse to GM and it's crappy transmissions??

• ENGINE

  TRANSMISSIONS ISSUES. Not transitioning/ shifting into gears smoothly or at all. When it does transition/shift it is rough and harsh. When my car transitions to a lower gear then it will not transition back up to a higher gear causing my vehicle to drop speed significantly that I am a safety hazard on the road. Example: when it shifts to a gear high enough that the vehicle can reach 40 mph and there is a need to decelerate it does but once it drop to lower gears it cannot engage again to a higher gear leaving me stuck going at most 10 mph with not opportunity to excelerate in traffic to a higher speed. The transmission control module (TCM) software was updated with no improvement.

• SERVICE BRAKES,FORWARD COLLISION AVOIDANCE

  I had an incident in my 2020 GMC Yukon, where the forward collision crash alert went off and there was total loss of brakes. The brake pedal went to the floor. After the crash alert ended, the brakes returned. This happened on the highway and could have turned into a disastrous event. The dealership has been unable to diagnose or recreate this issue. They claim they did not find anything and the vehicle is safe to drive. I have turned off the collision detection system in the meantime. I feel strongly that this is a software issue that needs addressed. GM has replied that they support the dealership but if I want a second opinion I can go to another dealership for input.

• ENGINE

  MISFIRE ON #6 CYLINDER. DIAGNOSIS REVEALED THE INTAKE VALVE IS NOT OPENING DUE TO COLLAPSED VALVE LIFTER. No message prior to engine light coming on and car shaking after driving back from the store (speed less than 45 MPH).

• ENGINE

  I purchased my 2020 Yukon Denali on July 8, 2024 from Classic Buick GMC in Painesville, Ohio. The check engine light started going on and off a few months after purchasing the vehicle. When I called a mechanic he stated that I should wait until the light is on and then bring in the vehicle. In early May 2025, I took my vehicle to Mike’s Automotive in Middlefield, Ohio after the check engine light began coming on during extended drives (approximately five hours or more). The shop ran a diagnostic scan and advised that the oil pump needed to be replaced. Seeking another opinion, on May 14, 2025, I brought my vehicle to Classic Buick GMC Service, the dealership where I purchased my GMC Yukon. After diagnosing the vehicle, they advised that the check engine light was related to an Engine Oil Pressure Control Solenoid stuck in the off position (P06DD). This fix would cost $3,584. This fix would require the oil pump to be replaced as indicated by the previous repair shop. On May 29, 2025, I took the vehicle to Avenue Auto Clinic in Painesville, OH, where the oil pressure valve and sensors were replaced. The mechanic also advised that I change the oil every 3,000 miles, use OEM oil filters, and thicker oil. He also advised me to check the oil every 1,000 oil and add as needed. I do have to add oil approximately every 1,500 miles and I change the oil every 3,000 miles. I am concerned that my vehicle has the same engine-related defect as the Yukon engines currently under recall. Multiple mechanics have informed me that my vehicle is equipped with the same engine as those affected by the recall. I am requesting that my vehicle be added to the recall. Yes, my vehicle is available for inspection.

• POWER TRAIN

  Transmission started slipping a little and then literally stopped working all with in an hour. And was doa in the parking lot.
