Intermittant slow, jerking when shifting gears. In 4wd rear wheels locked up on right hand turn, sliding through intersection. No warning or failure lights. Needs inspection and repair.
2022 Chevrolet Suburban, 3.0L Duramax diesel, 10-speed automatic, purchased March 2022, approx. 122,000 miles. In early August 2026 the transmission began shuddering at low speeds. Reported to the selling and servicing Chevrolet dealer on 08/11/2026 at 118,892 miles. No transmission diagnosis was performed; the dealer's written estimate recommended spark plugs on a diesel engine. The condition worsened. On 09/17/2026 the dealer verified the concern and documented a "very harsh shift which would continue until 5th gear" when accelerating, and found the transmission fluid "heavily contaminated with metal and clutch material." The dealer recommended transmission replacement at customer expense and stated GM Special Coverage N242454441 (transmission control valve wear, companion to Safety Recall 24V-797 / GM N242454440) does not apply because DTC P0747 is not set, although that bulletin lists harsh shifting as an effect of the worn control valve. The control valve body has not been inspected. GM's recall filing states this wear can cause harsh shifting and in rare cases momentary rear wheel lock-up. No warning lamps or messages appeared before the harsh shifting. No crash, fire or injury. The vehicle and transmission are at the dealer and available for inspection; a GM TAC/FSE inspection has been requested. Filing so NHTSA has a record of a 2022 Suburban diesel showing the recall symptom and being denied inspection on the basis of the P0747 code alone.
Just for information purposes, I have been an ASE certified Master automotive technician for 30 years. As I was accelerating onto the highway, my transmission downshifted hard, throwing everything forward. It then went into limp mode with “ses” light on. I was able to drive it home stuck in one gear. The next morning I tried to drive the truck. It had reverse but when trying to go forward, the transmission was stuck in between gears and fighting itself. I manually shifted into low gear and it seemed to clear up the binding. I drove the truck up and down my driveway which is about a half mile long. No more “ses” light but when I went to park it, there was no movement in reverse. As I researched the problem I found the recall information on the valve body. I called several dealerships to find a service writer that had experience with these transmission issues. The truck was towed to a dealership that knew about this recall. Their technician checked for codes but there were none. It seems these trucks reset or “lose” codes when the ignition is turned off. He checked the fluid and decided that the reverse clutch must be burned up. They quoted a transmission replacement at $6500. I asked if they had driven the truck forward at all to reset any trouble codes. The truck was “unsafe” to drive due to the random harsh downshift and erratic behavior. I went there(putting myself in danger) to drive the truck to reset any trouble codes. Within a mile the truck did the same thing. It stored a code P2732. I was informed that GM would not do anything for me unless there was a P747. After reasoning with the service manager and also GM, it was obvious I was out of luck. I had the truck towed home and removed the transmission pan. The fluid was clean and there was no debris. The problem is in the defective valve body from GM but since it didn’t have the code P0747 I’m stuck having to repair it myself. The truck has 126k miles still well within the extended service range.
I own a 2022 Chevrolet Suburban with approximately 115,000 miles. While driving, the check engine light illuminated and the vehicle suddenly entered limp mode. The transmission lost normal operation, including reverse gear, significantly limiting the vehicle’s ability to operate. The failure occurred without warning and created a potential safety concern because the vehicle could no longer respond normally to driving conditions. The vehicle was inspected by a Chevrolet dealership, where technicians diagnosed a failed transmission control valve body and confirmed the valve body required replacement. I paid to have the repair completed. After the repair, I learned that GM issued Special Coverage N242454441 for certain 2021-2022 Chevrolet Suburban vehicles equipped with the same transmission. The bulletin describes premature transmission control valve wear that can cause a service engine light, reduced engine performance, harsh shifting, and requires replacement of the transmission control valve body. My vehicle experienced the same failure and required the same repair, but my VIN was not included in the covered population. I contacted GM before authorizing the repair and requested assistance, but my request was denied because my VIN was not included in the special coverage. I am submitting this complaint because my vehicle experienced the same transmission valve body failure identified by GM despite not being included. I request that NHTSA document this failure and determine whether additional vehicles equipped with the same transmission should be included in any current or future safety investigation.
UNKNOWN TRANSMISSION ISSUES MENTIONED IN OTHER RECALLS FOR SAME PERIOD/MAKE MODEL AS LISTED YET MY VIN was not, as a mother 4 little ones I need my vehicle to perform as it was design to, the cost for this repair is over 6,000.00 I have already invested over 40,000 since I brought it. I feel they ought have included my car on this recent recall they had to have known this problem was of their why else would there recalls. I still must pay monthly for a vehicle that does perform as it should. This impacts my ability to provide for the needs of my children. I hope relief is on the way.
While driving down the high way with the check engine light on, a message appeared on the screen and said “unable to shift soon. Service transmission immediately.” After driving a few more miles the vehicle shifted to neutral, and then as soon as I got on the shoulder of the highway and slowed to approximately 5 mph, the vehicles wheels locked up and the car jerked aggressively into park. This exact issue has occurred multiple times while driving. It is unsafe to drive the vehicle.
Having reviewed online your safety recall number N252536750, I am experiencing the same issue (right rear wheel occasionally locks when starting from a standstill and turning right). It only lasts about 1 or 2 seconds while accelerating. However, when I discussed this with my Chevrolet Dealer, I was told that according to the VIN for my 2022 Suburban 3.0L Diesel, I am not part of that recall. I plan to take it to the Chevrolet Dealer very soon for more analysis. However, I wanted to bring this to your attention, as it could be hazardous. I have not gotten any dash warning messages. Thank you.
The contact owns a 2022 Chevrolet Suburban. The contact stated that while driving 50 MPH, the transmission unexpectedly shifted to neutral(N) and the vehicle shut off. The driver was able to coast safely to the side of the road. The vehicle failed to restart. There were no warning lights illuminated. The vehicle was towed to the local dealer, where it was determined that the engine needed to be rebuilt or replaced. The vehicle was not repaired. The vehicle was previously taken to the same dealer for a prior recall repair. The dealer had provided a loaner vehicle. The manufacturer was not notified of the failure. The failure mileage was approximately 58,166.
Check engine light with rough shifting and vehicle wouldn’t go in reverse. For safety reasons we had the vehicle towed to our local Chevy Dealership. Transmission needed a valve body rebuild. This is a known issue with this transmission but our VIN wasn’t under that recall.
In several separate unreplicable instances, the vehicle has turned off while driving, once on the highway, once on my street, once turning across heavy traffic, and others. I've almost died a couple times and I've taken it to the dealership several times, they have Not been able to find anything wrong with it and have been unable to replicate the issue. The engine has been replaced, and it was happening before and since. My 2023 is also doing the same thing.
The contact owns a 2022 Chevrolet Suburban. The contact stated that while his wife was driving at an undisclosed speed, the rear wheels seized. There were several unknown warning lights illuminated. The message "Reduced Acceleration, Drive with Caution" was displayed. The contact's wife pulled into a parking lot, but the transmission failed to shift into reverse(R). The vehicle was towed to the dealer, where it was determined that the transmission control valve needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 26V085000 (Power Train); however, the VIN was not included in the recall. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 86,000.
My vehicle was subject to a GM recall involving inspection of the 6.2L engine. The recall inspection was completed by an authorized GM dealership at 58,581 miles. The vehicle was cleared as passing the recall criteria and returned to me. Within fewer than 10 miles after leaving the dealership following the recall inspection, at approximately 58,590 miles, the vehicle experienced a sudden loss of propulsion while traveling at highway speed (approximately 65 mph) on a divided U.S. highway while ascending an incline. The vehicle shifted into neutral and lost engine power without warning. Steering and braking remained functional, but the vehicle lost forward motive power in the left lane of traffic. Attempts to restart the engine resulted in a loud mechanical thud, and the engine would not restart. The vehicle was towed to the dealership. The engine is now being replaced. Prior to this incident, the vehicle had previously undergone an oil consumption test related to engine concerns before the recall campaign. This failure occurred shortly after the vehicle was inspected and cleared under the recall procedure. I am reporting this due to the sudden loss of propulsion at highway speed following recall inspection and the subsequent need for complete engine replacement.
Hi my 2022 chevroley suburban has been sidelined for more than two months with a problem that involves my cylinder number 5 ( lifter and camshaft or crankshaft ) i believe. a well known issue with these cars. i happened just a few miles out of my warranty. when i went to chevrolet to explain to them. they didn't want to fix it. i have two young children that i take to school with this vehicle and they won't help me. this is a known issue with this model and it has been recalled many times. i'm stranded because of this car being out of an engine ... mind you the problem started well before my warranty and i was thinking that i needed some spark plugs ... by the time i realized it ... it went right over my warranty.
Summary: Sudden loss of engine power while driving due to lifter failure. Details: While driving my 2022 Chevrolet Suburban equipped with the 5.3L V8 (RPO L84), the engine suddenly lost power without warning. The vehicle began misfiring and lost propulsion in traffic, creating a hazardous situation. I was unable to maintain normal speed and had to maneuver to safety while the truck rapidly lost power. The dealer later diagnosed the problem as a collapsed lifter/valvetrain failure — an issue that GM has already documented in service bulletins (PIP5776G, 23-NA-043) and a service update (N212353840). These bulletins show GM has long been aware of defective lifters in 5.3L engines. This is not just a drivability concern. A sudden engine failure and loss of propulsion while driving poses a clear safety risk, especially when merging, crossing intersections, or towing. I maintained the vehicle properly and have all service records. I request NHTSA investigate these widespread lifter failures in GM’s 5.3L V8 engines as a safety defect, since they can and do cause sudden loss of power in motion.
Engine Coolant Control Valve sticking and causing the fan to run continuously. (P1098). Seems to be an issue with several people.
See attached document for complaint.
Coolant control valve failed and needs replaced. Which left me and my 3 children (one being [XXX] ) stranded on the side of [XXX] for 2 hours before someone could get to us. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Our 2022 suburban with the diesel motor has had 3 separate incidents where by all accounts the wheels have locked up while driving. The incidents mirror what has been described in the recall N242454440. The first time the incident occurred, we were driving while towing a light load (boat ~2500 lbs) at a steady speed of 60 mph. While driving the vehicle shook violently once, and then again about 2-3 seconds later. I immediately pulled over suspecting that maybe there was an issue with our trailer. After finding nothing we drove home without incident. Shortly after this incident we had the transmission flushed for regular maintenance at about 50,000 miles. Approximately 5-6 months later the second incident occurred. While driving with no trailer, up a mountain in NC at a steady speed of 35 mph, the vehicle shook violently and then again approximately 2-3s later. Each time the vehicle shook a loud "BUMP" noise would be heard. The road was smooth and was later driven on without issue so it was not the terrain. I once again got out and inspected the vehicle and was unable to find an issue. We drove to where we were staying and immediately took the vehicle to a dealer the following day to be inspected. The dealer found no issues and we did not report any similar problems. The last incident occurred after another 8 months while towing a light utility trailer at a steady speed of 60mph. Same thing happened with a shake and loud BUMP. However this time it was not followed immediately by an other instance. Those came approximately a minute later and then again after about 10 more minutes. I cannot recreate the issue and it seems to be at complete random and is happening while driving steady rates of speed where the transmission shouldn't be trying to shift. It seems like a safety hazard that could cause an accident.
When attempting to drive from a stop light or stop sign, after taking your foot of the brake, the vehicle intermittently completely turns off. It will not immediately restart and you find yourself stuck in the middle of an intersection creating a safety issue. The vehicle has been in to Chevrolet to have this issue fixed once already and it continues to repeat. I doubt the dealer has been able to replicate the issue as they haven't gotten the vehicle back into the shop after it's been sitting there for a week. There were no warning lights, messages, or other symptoms. It has happened to both myself and my wife, most recently on or about 7/1/25 where it happened to my wife multiple times causing us to leave the vehicle at the dealership for service. Just to be clear, the issue with the vehicle turning off is different from the standard auto stop/start feature.
Valve Body issues under powertrain factory warranty. Recall needed due to unreasonable national parts delay.
While driving on vacation our car just slowed down gave the message, “reduced acceleration, drive with care” and then shut off while on the high way. We were able to start it again but after that haven’t had that message but have had the message to service safety restraint system multiple times. I have taken my SUV to the dealership multiple times for both issues and they have said multiple codes generate but they can’t find anything to fix.
On January 29, 2025, while my wife was driving our 2022 Chevrolet Suburban with a 6.2L gas engine on a state highway, the vehicle suddenly lost acceleration and power to the wheels while accelerating to the posted 55 mph speed limit. This occurred without any prior warning, creating a highly unsafe situation in morning commute traffic. The vehicle was immediately taken to a Chevrolet dealership, where the issue was diagnosed as a failed transmission control valve. This failure, which resulted in a complete loss of power while driving at highway speeds, is a known defect affecting certain GM models. The part in question, the Transmission Control Valve, is currently in high demand and is on a national backorder due to numerous similar failures. A recall has already been issued for diesel engine models with the same problem, but no recall exists for the gasoline-powered versions like ours. Chevrolet has confirmed the diagnosis and is aware of the issue, but the replacement part is currently on a national backorder, and the repair has been delayed indefinitely. Since the incident, the vehicle has been undriveable, causing significant inconvenience, and Chevrolet has been unable to provide an estimated date for repair. The sudden loss of power created a dangerous situation on a busy highway, as there were no warning lights, messages, or symptoms prior to the failure. This is particularly concerning given that the part involved is on backorder due to the widespread nature of the issue. Chevrolet's lack of a clear repair timeline, coupled with the fact that this issue has been identified in other models, raises questions about the company's response and whether a broader recall or safety bulletin will be issued for vehicles like ours. The vehicle’s failure has not only been a major inconvenience but also a safety concern, highlighting the need for urgent attention to address this defect.
While driving from work to the gym (03/04/25), I was stuck in traffic due to a wreck; when traffic started moving again, I didn't. It was like it was in neutral and was just sitting there revving the engine. It finally started moving but clearly not functioning properly. A few miles later the Check Engine light came on with a "Reduced Acceleration Drive with Care" message displayed on the dash. I limped it into the parking lot and as I tried to back into a parking space the vehicle stalled and put itself in park. Finally was able to get it into a parking space to wait for a tow truck to have it towed back to the dealership. Chevy dealership has informed us that it needs a torque converter and a valve body (03/06/25) and they will create a "SPAC case" with GM as it is still under power train warranty. No eta on parts. Supposed to hear from Hertz on a rental (no more than $45 coverage a day; so likely not going to get a similar vehicle as a rental); no further news as of today 03/07/25. We bought the vehicle less than a month ago and haven't even made the first payment (other than the down payment); looks like that will occur and we won't even have a car to show for it.
The “add engine oil” light kept coming on and I initially thought it was because they forgot to reset it after my oil change because my car wasn’t reading it was due for one. I came to find out that my car is likely burning excess oil, according to the dealership, since all of the oil was gone. GM says that it’s normal to burn oil and as long as it’s up to 2 quarts between oil changes it’s fine. The dealership recommended that I get oil consumption test and sometimes it burned more oil than normal and other times it did not. We had to go every 1,000 miles which was an issue because it’s our main vehicle for family transportation and sometimes I would have to go under 1,000 miles because we needed it for a longer trip and would be over if waited until we got back. Also, my engine fan was making a very loud noise that would run for a while after my car was turned off and I was told multiple times it was fine until one time they checked it and it was indeed an engine malfunction and my engine would overheat when I went above a certain speed. The first fix wasn’t right and had to go back. I wasn’t burning enough oil to warrant GM to do anything.
Engine failure, losing engine coolant and engine oil. After change oil, roughly 1500 miles, engine losses about 3-4qts of oil.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
