This problem isn’t just the 6.2L engine. My 22 Suburban has the 5.3L and had engine failure on the freeway going 70 mph in April 2026. Loud noises and loss of power. Towed to dealership and was confirmed that it was the same issues as the 6.2L. The dealership only replaced certain components (gears, rods, camshaft etc.) Parts replaced and vehicle returned a month later but still loss of power and bad idle. New dealership in May 2026, replaced same parts, said faulty parts were used at previous dealership. Vehicle repaired and returned in June2026, a day later new code for service transmission now code thrown and parking break not working. Returned to dealership and said it was a fuel pump module? failed. No vehicle for 3 months and lots of headaches. This recall needs to be extended to the 5.3L engine as well. Needs full replacement, not just repaired. My vehicle still doesn’t run great but Chevy will not honor anymore repairs.

The engine seized as we were driving 65mph on the highway on a family trip. Had no warning sings or any dashboard lights come on. The vehicle just put itself in neutral and we coasted down the road until we came to a complete stop. Had the recall done a year ago for it. The dealer confirmed now that it was a catastrophic engine failure.

The contact owns a 2022 Chevrolet Suburban. The contact stated that while driving at highway speeds, the vehicle shut off while displaying "Service Transmission Now Unable to Shift Soon" and "Engine Power is Reduced" warning messages. The vehicle was towed to a dealer where it was previously inspected under the federal safety agency Campaign Number: 25V274000 (Engine and Engine Cooling); however, no repairs were performed. After remaining at the dealer for nearly eight weeks, the engine was replaced under warranty. A few weeks after the replacement, the same warning messages were displayed on the instrument panel upon startup. The contact attempted to drive the vehicle; however, the vehicle failed to exceed 20 MPH and was towed back to the dealer. While attempting to drive the vehicle into the service bay, the technician experienced severe hesitation and engine stalling. During diagnostic testing, a large amount of metal shavings was discovered in the oil filter, and the vehicle was diagnosed with the same engine failure as before. The vehicle was repaired; however, the contact refused to take possession of the vehicle due to safety concerns. The manufacturer was notified of the failure, and a case was filed. The failure mileage was 61,000.

Operating vehicle normally until one day I heard a rattling noise from the engine compartment. Car had limited speed and i had to pull over to check what the issue was and the car wont start. No check engine lights, no warning. Tried turning car on but only the car starter keeps rolling. Tried jumping and it doesnt start and had to have it towed to the dealership. Car is under 55,000miles and dealer diagnosis indicates there are metal particles in the new oil after replacing oil and a loose bearing. States i will need a new engine, which is on back order and GM will only cover $44/day until repair is complete. All maintenance and oil change invervals were kept up to date. Other days when I start the car, the main HUD with the speedometer does not turn on. Pitch black... I can drive but not know what my speed is. I had to disconnect battery and reconnect to clear the issue. It has happened several times.

Had the recall service done , where they change the oil weight, to the 6.2 L engine and just a few months later the engine died while driving on the highway . It just stopped running. The car is only 3.5 years old and the engine died. They took it apart and said it was a non effected part that failed but i find that crazy. No warning just complete shut down. I was luck and only going about 30 MPH on the highway due to heavy traffic. But then needed to sit on the highway for hours weighting for a tow. The kicker is the car would not go into neutral and made everything so much harder.

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.
