Filed Oct 30, 2026 · Transmission · TX

Check engine light came on and car was shuttering, and locks would lock and unlock. Took it in to dealership, they then said I needed a transmission flush. I did that and paid for it. I experienced the same issue, check engine light again, car turned off while heading out of town, pressed the push start and it turned right back on. Took it to the dealership again and they said wiring harness needed to be replaced did that and paid for it. Issues continued, now the doors are locking and unlocking, I could now not back up, almost as if the back was locked up, gears would not shift. Took it to the dealership again and they now said the transmission needed to be replaced. We did that and paid for it, the issue has resolved, after several trips to the dealership and expenses later. Wanted to have this documented, for any other who may having this issue. Could have been worse had the car not turned back on right away while driving out of town. *CVT Transmission Service: vehicle has a shudder when driving, recommend a transmission flush *Transmission Valve Body: Found fault code P0776 (Transmission Control Solenoid Valve 2 Stuck Off) I do see there is a transmission recall although when I put my VIN it does not indicate the recall for my vehicle

While driving in passing lane on interstate highway at approximately 65 mph engine lost power. Dashboard warning "vehicle in neutral" message appeared. "Press start" message appeared. Tried to start the engine but did not start. Slight downhill while on highway and had to make it to right shoulder since no shoulder on left side of highway. Glided across 2 lanes to right lane and luckily an exit came up while still gliding slightly downhill. Exited ramp and got off highway to an empty parking lot. Put vehicle in Park. Since engine failed, power steering was normal as was all electrical components. Once stopped, vehicle was not able to be shifted into Neutral. Message " unable to shift to Neutral under conditions " appeared. Vehicle had to be towed with rear wheels on dollies since it was stuck in Park. Was very lucky to get vehicle across lanes of traffic and off highway to a safe location. Had vehicle towed to nearest GMC dealership where it was diagnosed as internal engine failure covered under recall for this particular engine. (6.2 liter).

I was driving down the road and my vehicle went into limp mode, and I had reduced acceleration. I got to my destination then could not reverse the vehicle out of the parking space, reverse would not engage and allow me to have acceleration power. Because the parking space was on an incline we could roll backwards then drive forward, in limp mode, to a nearby mechanic. The vehicle diagnostic codes they got were: no reverse, p0700, p0776 and p18a1. They told us the repair needed would be to remove and replace the valve body assembly for $2,862.40. There were no warning lights that came on prior to the incident. Once the vehicle went into limp mode the check engine light came on. We had a Chevy dealer and got a second opinion at a transmission shop to check the transmission in December 2025, because we were concerned about a possible hard shift when shifting vehicle from park to drive, but both places concluded there were no problems. We now have had it towed to a transmission shop for a second opinion. It is available for inspection. We see a recall issued to other 2022 gmc Yukon xl that does not come up when we put our vin # in, but could possibly apply to our vehicle too is recall #: N252536750.

I noticed vehicle jerked a couple times when it shifted gears while driving. Shortly after, reduced power mode light came on. Vehicle did not shift past lower gears and had no reverse. Took to local dealership, they said it needed a transmission valve body overhaul. This is a known problem with 2022 gmc yukon xl, however, they said it was not associated with my vin. This cost me almost $2,000 out of pocket to repair.

Two weeks ago I heard a faint ticking sound. I had a professional look at it and they said that I had a cylinder sticking and to add an additive the next oil change. I still had 1,500 miles until then and so I did not do that. That noise stopped a day later. Last Friday, it started to tick again, and then it got very loud. I live rurally and was 45 minutes from home. The engine went from ticking to full clunking and very low power in just a moment. I luckily found a small engine shop to check the codes, but as I was parked there, the car would not go in reverse! He had to clear the codes to get it to go into reverse. I had to then slowly drive 45 minutes back to our small town. I drove to and immediately parked it at our local repair shop. It can not be driven now. The lights that came on were the Rear axle system off, forward collision system, service traction control, engine light flashing, and service ESC light. Not to forget that it would not go into reverse. Also the suspension system seemed to malfunction and not lift or lower the car.It seemed to clunk and try, but nothing happened. The whole car basically went down. I see there is a recall for this year or car, but my VIN is not included. I am hoping that it will be included as the repair shop is telling me it will be close to $10,000.
