2022 GMC Sierra 1500: stuck in gear or won't shift

Filed Nov 3, 2026 · Brakes, Electrical · OK

While the truck was under warranty it would go into limp mode. A dealer said they replaced the valve body but it did not look like anything had been done to it. It didn’t go into limp mode and seemed fine for a couple of months then it went into limp mode again and we took it back to the dealership. The hooked a scanner up and cleared the codes and it worked fine for a couple of more months. (This cycle happened repeatedly until it was out of the warranty.) We finally got our own scanner and cleared the codes like they did at the dealer and it would work fine for a while. Then one day driving at 60-65 mph it locked the rear wheels and we slid off into the ditch. It happened 4 more times before we got it home. (We were driving about 15 mph). We called the dealership and they said they couldn’t do anything since it was out of warranty and it could need a new transmission. It was never right from the time we bought it. The locking brakes could be fatal if it had happened on a busy highway. The first problem we had with it was the front grill flew off. We called the same dealer and they told us we pushed too hard on it closing the hood so they weren’t responsible. My husband fixed it and it never came off again but we saw later that it had been recalled for the same problem.

While driving my 2022 GMC Sierra 1500 (VIN: [XXX]) in active traffic, the 10-speed automatic transmission suffered a sudden and catastrophic internal failure. Without warning, the vehicle stalled in the middle of traffic and forced itself into a hazardous "limp mode," severely restricting my speed and acceleration. This created an immediate, high-risk safety emergency, leaving my passengers and me vulnerable to a rear-end collision before we could navigate out of the live roadway. The vehicle was towed to an independent facility (Kenny's Transmission, Repair Order #XXX) at 65,579 miles. Diagnostic troubleshooting confirmed a "Number 6 Solenoid Code" and "Internal Transmission Mechanical Failure" (3-4 races away, total loss of reverse gear), requiring a complete replacement of the transmission assembly utilizing an official GM service part at a personal cost of $6,673.10. General Motors has previously acknowledged 10-speed transmission control valve defects and wheel-lockup hazards by issuing safety recalls for diesel variants, but gas-powered models like my 6.2L L87 engine are experiencing identical, highly dangerous sudden losses of motive power without federal recall protection. I am requesting that the federal safety agency investigate this systemic failure rate on 2022 gas models before it causes a major collision.

On November 20, 2025, my 2022 GMC Sierra 1500 AT4 equipped with the 3.0L Duramax diesel engine began experiencing intermittent engine overheating conditions. Concerned about a potential safety issue, I contacted a GMC dealership and was advised that because no diagnostic trouble codes were present, there was nothing to diagnose or repair and that I should continue driving the vehicle. Over the following months, the overheating condition continued intermittently. On May 24, 2026, while driving on the highway, the vehicle suddenly overheated, displayed fault code P1098, and entered reduced power ("limp mode"). The vehicle lost normal performance and acceleration while traveling in traffic. This created a significant safety hazard because the vehicle was unable to maintain normal highway speeds, increasing the risk of a rear-end collision or other traffic accident. The loss of power occurred while driving and without sufficient warning, leaving the vehicle unable to safely perform as expected in highway traffic. After researching this issue, I found numerous reports from other GMC and Chevrolet owners describing similar overheating, coolant control valve, thermal management system, and P1098-related failures. Many owners report symptoms involving engine overheating, reduced engine power, and limp mode operation while driving. I am concerned that this may indicate a broader defect involving the vehicle's cooling system and thermal management components. The vehicle exhibited overheating symptoms for approximately six months before the final failure occurred. Additionally, I understand that certain GM vehicles have been subject to service actions involving coolant control valves and thermal management system components. Given the similarity of symptoms, I am concerned that the overheating condition reported in November 2025 may be related to the same type of failure mechanism, yet my vehicle has not been included in any recall or special coverage program.

Bought truck 0n 12/26/2025 from lot in Michigan had it transported to Missouri. First time I drive it Check Engine comes on and goes into "Limp Mode". Had it towed to GM Dealer and they say it was the high pressure fuel pump. Got it back and check engine light comes back on then goes off then back on again. Not happy at all!!!

The coolant control valve failed. This is a known failure point of poor design and on every other truck from 2019-2023 with the duramx LM2/LZ0 engine, they are covered by a special service warranty to 150,000 miles. GM knows this items fails and puts consumers lives at risk when the failure throws the truck into limp mode on the freeway. They refuse to do a recall to avoid doing the right thing. This is deceptive and wrong.

I was accelerating from a stop light at green. The RMP's revved up, truck jerked, and it would not shift or accelerate. I was almost rear ended on a busy street. There was not warning light prior. The service light then came on. I pulled over, turned the truck off. I turned it back on and put it in drive. It shifted to 30 mph, jerked, and would not shift. The message on the dash states it is in limited power, in limp mode. The GMC app states there is a Transmission system issue detected. My mechanic stated the control module is bad and needs replaced. I called GMC and they stated it is out of warranty by 4795 miles. Having a vehicle that will not accelerate on a busy street is dangerous. It is a 2022 with low miles. I limped it to my work office 2 miles away and called family to get me. I live 50 miles from work.

When putting the truck in reverse it did not go, then suddenly squealed the tires and engaged reverse. This happened 2 days in a row. On the 3rd day, it would not go into reverse at all and had to be pushed in neutral from a parking space to be able to drive forward. At that time, it was at first jerky but did go forward. Subsequently, I did not drive it until my appointment with the dealership and I was able to put it in reverse.

Initially experienced hard clunking sound when transmission shifting between 35-40 mph. I took in for service and dealership replaced EGR sensor. The problem was not resolved with this fix. I took the vehicle back for service and the dealership then did a software/system reset. I then drove my truck with towing a trailer to San Diego and upon exiting the freeway, the back tires locked up causing a screeching of the tires which caused my vehicle to swerve. I felt as though this could have caused an accident. Shortly after, the engine light came on and my vehicle went into “limp mode”. A dealership in San Diego then told me that the valve body plate would need to be replaced. According to the internet this seems to be an ongoing issue with this year’s vehicle, yet no recall has been issued by GM. I understand GM has issues a special warranty coverage #N242454441 providing extended warranty for control valve issues. I’ve been told my VIN is not included for this special warranty when it is the exact same issue.

Purchase a used 2022 GMC Sierra 1500 Denali with a 3.0L diesel at around 42,000 miles. Drove it for about 1,500 miles before I started noticing unusual shifting with the transmission which became more noticeable with time. At around 44,000 miles, the truck had two hard shifts going 35-40 MPH on a flat round and put itself into limp mode. Turned off and on the truck multiple times, the engine light always stayed on but the symptoms would come and go. Either way the truck always went back into limp mode after a few miles. I did a quick scan and it came out with a P0700 and P0746 code. I limped it to the dealer and was told that it was a bad valve body which is apparently on back order with no ETA and they can’t tell me when I will get my truck back.

While driving on streets and freeways the truck will shift hard and then loss of acceleration and into limp mode. Lights all on dash go crazy like brakes, 4WD, fuel gauge and check engine light. It has done it 8 times now and has been in the shop 5 times with same issue. Major safety issue while driving 70 mile hour then governs it at 55-62 mile per hour.

Driving 70 mph on highway and the engine shut off. Dash says shift to park to restart. Pulled over and put the vehicle in park and pressed engine start. Vehicle did not start back up. (No crank no start) Vehicle locked in park and wont shift. Vehicle was towed to my house. Replaced battery bus bar and vehicle started back up. Test drove and shut off again in my driveway. Will not restart. No engine light on. 124k miles on it. No warning of this happening. Vehicle randomly will shut off. Sometimes it turns on. Been parked since January in my garage for safety concerns until I learn of a repair.
