Vehicle was recalled for loss of propulsion.Pico test was done ,changed oil.6,000 miles later engine locked up on freeway.Engine is in for replacement.2022 suburban 6.2 liter 66,000 miles
2/24/2026 Sitting at red light, very busy road, vehicle cut off and said push to start. Vehicle would not start and would not shift out of park to push out of road. Very dangerous to be stranded in moving traffic. Had to be towed to dealer and it's still there waiting on engine replacement.
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.
I own a 2022 Chevrolet Suburban RST that has experienced ongoing mechanical and safety issues over several years. I first began reporting drivability concerns to General Motors and the dealership in 2023 and continued contacting them throughout 2024 and 2025. During one dealership visit, a sales advisor rode in the vehicle with me and stated they did not observe any issues, despite my continued reports. The vehicle later suffered a loss of propulsion and required a full engine replacement. The radiator and cooling components were also replaced by a Chevrolet dealership. Due to ongoing concerns for my safety, I contacted General Motors multiple times, requested an executive buyback, and asked about Lemon Law options. GM advised that the engine had been replaced and that I needed to take ownership of the vehicle. After picking up the vehicle last Wednesday, I immediately noticed a persistent sweet coolant/radiator odor inside the cabin and outside the vehicle that continued for nearly a week. I also experienced engine hesitation/stuttering when stopped at traffic lights as the auto start/stop feature reengaged. I attempted to contact GM again regarding these concerns prior to today’s incident. Today, while driving, the vehicle displayed an engine overheating warning instructing me to turn the car off immediately. I safely pulled over and shut the vehicle down and am currently stranded roadside. Given the repeated failures, history of loss of propulsion, multiple repair attempts, denied buyback requests, persistent coolant odor, drivability issues, and now overheating shortly after engine and radiator replacement, I believe this vehicle presents an ongoing safety risk and request formal investigation.
On Saturday, 11/29/25 @ 3PM, while driving on I-75 from GA to MIA, our 2022 Suburban VIN: [XXX] sudden & unexpected had a mechanical failure. Without warning, vehicle stalled/ stop while traveling at highway speed, leaving us seconds to maneuver to the side. This failure created an extremely dangerous situation that could have resulted catastrophic or fatal accident for my family. Check engine light came on (code P102A). An officer stopped to assist & arranged car to be tow which we had to pay $135 to nearest Chevrolet dealership. Since the dealership was closed, I was forced to stay an additional night in a nearby hotel and paid $106.46. The vehicle was inspected by Countryside Chevrolet, who diagnosed the issue as a failure of the fuel pump control module however I was informed that this VIN was not covered under warranty or any special coverage, despite the fact that we experienced the exact same failure on our 2021 Chevrolet Tahoe, which was covered under warranty for this same defect. I was forced to pay $708.72 for the repair. This inconsistency is unacceptable—especially considering GMs extensive history of complaints, recalls, & class action litigation involving defective fuel pump & fuel system components, which present a well-documented safety risk. I filed a complaint with GM Customer Care (Case XXX). I submitted all required receipts for repairs, towing & hotel, however GM denied my claim without providing any explanation, only stating VIN was “not covered.” Also, GM refused to provide a written justification & my request for a manager callback was ignored. No consideration was given to the safety implications of this failure. This response is unacceptable & demonstrates a failure to take responsibility for a known safety defect. Demand: Given the seriousness of this incident, the documented defect, & GM’s prior knowledge of same failures, I demand full refund of $950.18 for expenses. This situation could have ended tragically. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA
The contact owns a 2022 Chevrolet Suburban. The contact stated that while driving approximately 60 MPH, there was an abnormal scraping sound coming from under the vehicle. After stopping to inspect the vehicle, the contact discovered that the fuel tank had partially detached from the subframe and fuel was leaking from the fuel tank. The vehicle was towed to the local dealer, who replaced the fuel tank. No further information was available. The cause of the failure was unknown. The manufacturer was notified of the failure. The failure mileage was 40,000.
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.
Driving down to Florida, No warning, no lights, never any issues except a belt replacement. I get oil changes, tire rotation every 3500 miles. Almost got killed doing 75 miles per hour, engine sputtered, totally shut down. Coasted onto an exit ramp thank God it was right there or we could of been killed. Tow truck towed to Davis Chevy Gainsville, they called me on Monday said good news I have a warranty bad news Total Engine Failure, will take 3-4 weeks to replace. Now I am trying to find a GM rental large enough to get me and my family back to TN since GM said they will only pay for a GM rental car. Scary, could of gotten killed. NO NOTICE FROM GM ABOUT ANY POSSIBE PROBLEMS....WE ALMOST GOT KILLED AND CRASHED along with the other drivers on the road. Thank God it was a Sunday and 6 am so not much traffic or it would of been worst.
Engine lost power and stalled without warning while driving down the highway. Coasted to side of road and was unable to restart engine. After engine stopped, dash indicated low fuel, although tank was 3/4 full. After coming to a stop, was unable to shift out of Park (which could have been a major issue if I had not been able to clear the highway before coming to a stop). Towed vehicle to closest Chevrolet dealer, who replaced the fuel pump control module. Dealer indicated that this is a common failure item to the point that they stock the part and suspected what the failure was based on my description. When pressed, the dealer representative also noted that GM has not updated or redesigned the factory installed fuel pump control module ("the new module installed is exactly the same as the one that failed"). Fortunately, traffic was light and I was able to pull to the side of road. This would be extremely dangerous if it happened while driving on a multi-lane expressway and we were trapped at a stop in heavy, fast moving traffic.
I WAS DRIVING HOME AT HIGHWAY, I HEAR NOISE SCRAPPING NOISE FROM UNEVEN PAVEMENT AND ROLL OVER SPEED BUMP AND A PIECE OF METAL LIKE U SHAPE FELT OFF. WHEN I GET HOME, INSPECTED I SAW MY VEHICLE FUEL TANK HAGGING ON ONE SIDE. FOR SAFETY TO PREVENT TANK TO FELT OFF I HAVE TO GET A STRAP TO SECURE IT THE TANK TO THE FRANME .
High pressure pump failed at 73000 miles.
When I started up the vehicle with the key fab button I noticed the cabin air blower came on as normal however when we went to the cockpit we noticed the engine was not running. When we went to start the vehicle (holding break and pressing start button) the dashboard started the Z71 launch sequence and then went to a dashboard as if I was in the normal drive mode however the dashboard was extremely dimly lit as if the backlight was not on and the engine still was not running. After several attempts to start using the brake+start button method we noticed a clicking sound that seemed to be coming from the engine cabin just in front of the passenger cabin however it would never ignite/start the engine. After several attempts to start the engine through the brake+button, we tried to just press the start button, which would sometimes be prompted on the dashboard, and get some feedback from the dashboard through better backlighting and messages I now cannot recall but never ignited the engine. When we tried again with the key fab x2 button (hoping it would either start or "cancel" the current vehicle state), we received no response from the vehicle. When we attempted to shift, it stated the "conditions were not met", which I perceived as the correct response. The vehicle was stuck in this "mode" with the air blower still running and exterior lights still on and it was only a matter of time until the battery ran out. When it ran out later that day (though not completely ded) in rebooted in the same tweener mode. However, when we came the next day with a tow truck and a fully dead battery in the Suburban, the vehicle booted right up as normal. The tow truck driver indicated several new Tahoe drivers experiencing the same issue. To me, this is a software launch issue. While the vehicle was not perceived to be in danger, it left us stranded in what could be a dangerous location. Several episodes as reported by tow truck. Unsure if inspected. No symptoms before problem.
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.
