2022 GMC SIERRA 1500 Complaints

Upper grille deflector flew off vehicle while operating. No previous damage, just flew off. There is the same issue with my make and model that gmc issued a recall for but it is not appearing for my VIN

54k miles. Crankshaft failure. Truck shut off and put in neutral while driving with no codes on dash. Got a text saying to service engine and transmission immediately. On a side note, it is bullshit that you can't put the truck in neutral to get it off the road. The dealership is also doing a great job covering it and offering a loaner.

To start off my truck has been to the dealership multiple time for the camera. After third time in the shop they fixed that issue. Then the infotainment started acting up after about 4 times in the shop it was fixed. They gave me the prescribed fix for the engine recall in november. Engine passed the test. Then 3 weeks ago the engine siezed up from the crank and bearings on the interstate doing 70 pulling a trailer in traffic. Leaveing me and my dad in the middle of the interstate. I had to have it towed 2 hours to my house. After the prescribed engine fix. They replaced the motor in 3 days. Great right? No they did not test drive long enough. Or they would have felt the shudder that developed after the new engine went in. It is now about to go back to the shop. Because of the shudder at low rpm and im haveing electrical issues again as well . My remote start also stopped working after the engine replacement.

1) Component/System & Availability for Inspection Transmission control system. When shifting into reverse, the CHECK ENGINE lamp flashed and a “Transmission Service” warning appeared. Dealer retrieved DTC P07B4 and documented: “DIAGNOSIS OF ENGINE/CHECK ENGINE LAMP - CUSTOMER STATES WHEN SHIFTING IN REVERSE CHECK ENGINE LIGHT CAME ON FLASHING AND WARNING MESSAGE ON FOR TRANSMISSION SERVICE. CHECK AND ADVISE. NOTE: CUSTOMER DOES NOT FEEL ANY ISSUE WHEN DRIVING. SAVI CODE P07B4.” The component remains installed and is available for inspection upon request. 2) Safety Risk A transmission control malfunction can lead to unpredictable shifting or loss of propulsion, posing risk during reversing, crossing traffic, or merging. 3) Reproduced/Confirmed by Dealer? Yes. Dealer confirmed the condition and stored code P07B4 consistent with my report. 4) Inspected by Others? Inspected by an authorized GM dealer. No inspections by police/insurance/others. 5) Warning Lamps/Messages & Onset Yes. The CHECK ENGINE lamp began flashing immediately when shifting into reverse, with a “Transmission Service” message. I did not feel drivability issues at that moment. Addendum — Link to GM Safety Recall N242454440 GM Safety Recall N242454440 addresses excess wear of a transmission control valve that degrades hydraulic pressure, causes harsh shifting, and—rarely—momentary rear-wheel lock-up during a downshift. The remedy is a TCM software update that monitors valve performance and detects wear ~10,000 miles before a potential event; if detected, the transmission is limited to 5th gear and warning messages appear. My transmission warnings and DTC indicate a transmission control/pressure concern consistent with the recall subject. I request that NHTSA consider this complaint related to N242454440 and ensure appropriate recall remedy and coverage. (GM service bulletin/stop-delivery and NHTSA filings corroborate these details.)

I purchased my vehicle in June 2025. In January of 2026 the vehicle would sometimes shut down at red lights, requiring me to restart. No engine codes would pop up. On Jan. 16th, 2026, I exited my vehicle and heard a “cow bell clunking” coming from the engine area. I scheduled a service, and I was informed that the issue was part of the GM recall for 6.2L engines. This concerned me, because my vehicle had already had the “remedy” for the recall (changing engine oil type) prior to me purchasing it Certified Pre-Owned, and the engine still failed. The dealer I brought the truck to did a full engine (and appropriate parts) replacement as part of the open recall.

I was driving my 2022 gmc Sierra with the 6.2 engine 10 speed transmission and I was at at a red light, the light turned green and I went to go and I could feel my rear wheels lock up and then it released went into limp mode was not shifting gears correctly and I had no reverse

after i had the car inspected per thier recall on potential engines issues, the car passed and was told no issues. 6 months later driving on highway with family during rush hour and suffered complete engine failure going 70 mph. Lucky not to have been hit from behind. scary to be on highway like that. It was freezing outside. Dont understand being told car is fine and then this happens.

On November 16, while driving on the highway, my GMC vehicle suddenly lost engine power without warning. I was forced to stop in traffic, creating a dangerous situation and putting my life at risk. The vehicle required towing and has remained at the dealership since that date. The dealership determined that the engine requires replacement. Repairs have been significantly delayed, including an incorrectly ordered replacement engine, and the vehicle remains out of service more than two months later. This defect caused a sudden loss of power while driving and presents a serious safety concern.After the incident, I contacted the dealership immediately. Diagnostic appointments were scheduled and then canceled by the dealership twice, which delayed inspection and repair. I was only able to leave the vehicle at the dealership on December 12 due to these delays.

My vehicle stop running as I approached a traffic signal and failed to restart, it happened at a heavy traffic intersection during morning commute,I had the vehicle towed to Dealership that same day (01-22-2026). Later that evening the dealership called to inform me that the motor was blown and had ordered a new one.the mileage is approximately 39,285.

My TAILGATE kept opening randomly and ENGINE WAS MAKING CLUNKING SOUND initially. Lost many tools on the highway once when it opened. Dealership told me my truck is not covered under a recall for both issues, even though other similar vehicles are. I refused to pay anything to have it fixed. They claimed my truck “wasn’t built in the factory that has recalls”. A month later the STARTER AND BATTERY burned up when I started up the truck, something locked up it sounded like. Eventually it started but didn’t sound right. A few days later the engine finally blew up. I paid out of pocket for everything for that trip. It’s currently back at the dealer being repaired with a new engine for the recall but GMC refuses to pay for the initial clunking/starter/battery and the tailgate issues. I’ve encored so many charges with tows and rentals from all these issues. I would like full reimbursement for everything.
