2022 GMC Yukon: won't start

Filed Nov 3, 2026 · Engine · NV

My brother and I were on our way home from Phoenix to Las Vegas, driving about 70 mph when my 2022 GMC Yukon Denali suddenly shifted into neutral. We pulled over and had to restart the vehicle. We started driving again and a few minutes later the car shifted into neutral for the second time. We pulled over, restarted the car, drove for about a minute and it happened a third time. There was complete loss of control of the vehicle, thus we had no choice but to pull over again. The vehicle completely seized up and would not start again. The car issued a warning stating, “hot oil temperature.” It then issued another warning, stating “low battery,” though all the lights and power were working. The car issued available for inspection at Liberty GMC in Phoenix where I had to have it towed by my AAA. We then had to rent a U-Haul to retrieve the items stuck in the back of my car, which was our reason for the trip in the first place. This situation put us in a dangerous and very unsafe position, as it was dark outside and we had no choice but to maneuver to the side of the road quickly, as cars were flying by on the highway. The engine failure has been confirmed by Liberty GMC, where the car is still sitting and awaiting engine replacement. The vehicle has only been inspected by GMC service at Liberty GMC, to my knowledge. There were no warnings prior to failure. The warnings I mentioned above only happened after the fact.

Engine would tick and burn oil after the updated recall was done. There would be a hesitation occasionally when applying gas when pulling out from stop sign or stoplight. The engine stalled and would not restart. It would crank over but it was a super fast and elongated turn over. We had to call a tow truck and have it towed. The dealership said they found nothing wrong and sent us back out with it. We sent it to another dealership would replaced the auto start stop switch, changed the belts, and did a fuel/valve treatment to clean the fuel system. We got it back and ran it less than 30 days when we picked it up from the dealership after we changed the engine oil, my wife headed out of town on the highway headed to pick up our daughter and the car made it less than 6 miles before it lost power and shut off going 65 mph and almost caused her to get in a wreck. The engine did not turn back over and would not start. Sent it back to the dealership and they found a crank bearing had seized and they replaced the engine. We just got it back but we are not holding our breath since we know so many people here in our small town who have had their engines replaced and we have heard of people getting multiple engines replaced! There fix is not a fix and when these motors go down at highway or freeway speeds it is extremely dangerous. It’s also dangerous for people when they get stranded out in the middle of no where.

With no warning, my engine 6.2 L stopped running at highway speeds and failed to restart. The power train completely failed for a second time after having a previous engine replaced for the same failure in 2024. I had the car inspected per the recall along with changes in the oil viscosity as recommended along with service inspection. The car left me stranded again on rural highway for over 5 hours in temps that exceeded 98 degrees. The car would not start and went into a power save shutdown and had to be towed to the dealer. I was fortunate to have avoided any traffic on the highway enough to get the car off the road. This is not safe to drive on the highway and GMC has known defect and safety concern with this issue.

The engine began making a metallic knocking noise while at idle and very soon after began to make the same noise under acceleration. This noise sounded very much like the onset of rod bearing failure. The vehicle was driven straight home and parked. We called the dealership the next day and made a service appointment. As I drove the vehicle to the dealership, the engine noise became worse and was clattering very loudly as I pulled into the dealership parking lot. I pulled into a parking spot and let the engine idle with the transmission in Park while I was collecting some personal items when the engine stalled. I tried several times to start the engine but it would not crank. The dealership engine tech later confirmed that the engine was seized

While driving on the interstate at highway speed, the vehicle suddenly lost acceleration and stalled. I was forced to pull over. After stopping, the vehicle displayed a message to restart, but it would not start. All electronic accessories (lights, dash, etc.) remained functional, but the vehicle would not shift into drive or neutral. The message “Conditions Not Correct for Shift” appeared. Nearly rear ended, this created a dangerous situation due to loss of power in active traffic and inability to move the vehicle on a 250,000 vehicle per day very busy tollway.

In 2023, the vehicle began exhibiting erratic transmission shifting behavior, including harsh and unpredictable shifts while driving. The vehicle was taken to a GMC dealer for diagnosis and repair. Recently, the vehicle developed additional drivetrain and engine control issues related to the crankshaft position sensor circuit. The vehicle stalled while driving on a highway mountain overpass with multiple vehicles traveling behind me. When the stall occurred, the vehicle shifted into park and would not restart for several minutes. This created a hazardous situation due to loss of propulsion in active traffic at highway speed and limited shoulder space. Following diagnosis, the servicing dealer determined that the engine wiring harness requires full replacement due to internal wiring integrity issues affecting critical engine control signals. The crankshaft position sensor and related wiring are essential for engine timing and propulsion. Loss or corruption of this signal can result in reduced engine power, erratic transmission behavior, stalling, or no-start conditions. The earlier erratic shifting behavior appears consistent with conditions described in GM Technical Service Bulletin 21-NA-149, which identifies engine harness-related causes for drivetrain and shifting concerns. This issue appears to involve degradation or defect within the engine wiring harness affecting engine management and transmission operation. Given that this condition resulted in a highway stall and temporary inability to restart, I am reporting this for investigation as a potential safety-related defect involving loss of propulsion.

I purchased a Yukon Denali 6.2L in March of 2022 brand new from Bob Johnsons in Rochester NY. On [XXX] at 12,577 miles the engine went through a catastrophic failure, while driving, the vehicle began to make very loud noises. The vehicle was taken to Bob Johnsons GMC 4389 West Ridge Road Rochester, NY 14626. The repair notes #3 main bearing thrust portion had come apart. The vehicle was out of service from 4/3/2023 to 4/19/2023 for engine replacement. On [XXX] at 50,244 miles on the vehicle, I was driving down a busy highway during holiday traffic and the vehicle went into neutral and would not start, we immediately turned the flashing lights on, unrolled the windows and began to show distress to ensure we were not hit by passing cars. We made it to safety and called Onstar for assistance, on this occurrence due to the vehicle not starting we were unable to get the vehicle back in to the neutral position to be able to roll the vehicle. The vehicle was towed to Bob Johnsons GMC due to the Thanksgiving holiday, the vehicle was brought in 11/28/2025, and deemed to need another engine replacement. On November 28th I called to file a claim with General Motors and was called back by Stephanie on November 29th and was told they would get back to me if they had any options as now this is the 3rd engine replacement. On December 3rd, a new woman called also named Stephanie and advised me they were still undergoing options, as I requested a Buy Back with Trade Assistance. On December 9th, my final call from General Motors advisor Stephanie, I was told I do not qualify for a buy back because I placed too many miles on the vehicle between engine failures. The vehicle was out of service from 11/26/26-12/29/26 for engine replacement. On [XXX] 2 weeks and 4 days after the vehicle going back into service, the engine failed again, only driving approximately 245 miles. I am currently waiting on the 4th engine replacement with no updates. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6

On the morning of Thursday, [XXX], our 2022 Yukon Denali departed from West Richland, WA with the intent to arrive in Spokane, WA. After a short stop in Ritzville, WA around [XXX] local time, we entered the freeway ([XXX] to Spokane, WA) and attempted to pass a semi-truck. The vehicle got to approximately 60mph and then began to rev without any propulsion to increase speed. The vehicle shut off completely and stated that we were to put the car in neutral and attempt to restart. While going 50-60mph, we shifted into neutral and attempted to restart without any success. While the situation was extremely dangerous give the traffic (semi-truck on the right and an approaching vehicle directly behind us), we slowed the vehicle and maneuvered to the shoulder where we stopped the vehicle. The vehicle would not start so we leverage the OnStar system to call a tow truck. Unfortunately, there was no ride available being 1-2 miles outside of Ritzville, WA where transportation services do not exist. We requested the help of WA state troopers who picked up 7 of us (4 separate trips) on the side of the highway. The vehicle was towed to Spokane, WA and we were left to fend for ourselves to get to Spokane. The vehicle is in the shop and we are told based on the codes achieved that it is a full engine failure.

While stopped at a stop sign the vehicles start/stop activated and turned off the engine. When I released the break to hit the gas the engine would not turn back on. I was stuck in the middle of the road and unable to restart my vehicle. After several minutes of trying to turn the vehicle off/on it started back up. The second incident happened when using the remote start. Once I entered the vehicle and put my foot on the brake and hit the start button the engine completely died. Radio and heat stayed on but the engine wouldn't turn over. After letting it be for a half hour everything was still on inside the vehicle but the engine still wouldn't turn over. I disconnected the battery and reconnect it. Once that was done the vehicle started back up. Vehicle was brought to the dealership, but was told there is no fix and to not use the automatic start or auto start/stop on the vehicle
