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.

Incident

Feb 20, 2026

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.

Incident

Feb 3, 2026

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.

My 2022 Chevrolet Suburban 6.2L, approximately 96,000 miles. Vehicle was taken to dealership for transmission warning message and returned as “repaired” with a software update. The following day, February 12th, while driving at highway speed on the expressway, the vehicle suddenly lost power without warning. A message appeared instructing me to press start, and the vehicle shifted into neutral and stalled. No warning lights were illuminated prior to the stall. This created a serious safety risk due to sudden loss of power at highway speed.

I want to complain that my 6.2L V8 engine was “inspected” and they deemed it OK, then proceeded to make a requirement of thicker oil for its life. I was also given a long term warranty on the engine, however it is non-transferable, therefore the re-sale value of the vehicle is damaged beyond normal conditions. The engine is suspect, why else would it need thicker oil? The engine is all over the news with the recall, therefore why would anyone want to purchase my used vehicle based on that press and no further warranty? GM needs to make this right! That 10-year or 150,000 miles means nothing to re-sale value if is not transferable.

Car initially started stuttering on the high, check engine and traction control lights came on. I immediately went to the nearest Chevy dealership a mile away. Initially I had 20 error codes. The problem was the Left side lifters 4 of 8 stop working. Dealership recommended Replace Left lifters, 2 push rods, valve cove, head gasket. $5000. After starting the work. The technician could not repair the lifters because my camshaft is pitted and the RODS were rotating. Their recommendation is to replaced the whole engine to fully fix the problem. $12000 with 3 yr warranty. My SUV just 100kmiles.

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.

I own a 2022 Chevrolet suburban and bought the 72k mile extended warranty. Recently my telematics module went bad which is covered by the GMPP. I lost wifi, my clock is wrong everytime etc. However General Motors no longer makes this part anymore. Parts department utilizes a third party company called specmo for a refurbished authorized unit. However, GMPP will only cover the original msrp not the inflated price from the company specmo that GM uses for these parts. This part is 100% covered based on an msrp for a part that they no longer use and states that policy does not allow them to cover the full cost over the original msrp of the part. This is an issue that is all over the forums and internet and is ridiculous that GMPP is an extension/better than manufactures warranty yet they will not fully cover the full cost of the part that is covered. A few days later I was driving and my abs, traction control, steering, brakes, everything was flashing and not responsive or dramatically reduced like my brakes where I could not stop immediately with me and my 5 kids in the car.

Incident

Sep 22, 2025

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.

I own a 2022 Chevrolet Suburban (VIN: [XXX] ) that is included in NHTSA Recall No. 25V274 / GM Recall No. N252494000 for engine defects in the 6.2L L87 V8 engine. My vehicle was inspected at an authorized GM dealer today, on 9/23/2025 (Don K in Whitefish Montana). Instead of replacing the engine, the dealer performed the recall “remedy” of switching to higher-viscosity oil, changing the oil cap and filter, and providing an owner’s manual insert. However, the dealer service manager specifically told me that my engine will eventually fail due to the known defect and advised me not to drive the vehicle on long trips. He also told me to be careful driving if I have children, and it is only a matter of time before the engine fails, which will look like sudden shuttering, loss of acceleration and it will no longer run. He told me wait time to get a new engine after it fails is currently 8 months. This is alarming because the recall notice states that engine failure can cause sudden loss of propulsion without warning, which could be catastrophic going across multiple lanes of highway (from my home street), and entering and exiting my street via the 4 lane highway "suicide lane". I am very worried about this in the coming winter season with snow and ice. The current “oil upgrade” remedy does not resolve the underlying manufacturing defect in the connecting rod and/or crankshaft. Even after the recall service, my vehicle remains unsafe to operate, and the dealer’s own warning confirms this. I request that NHTSA review GM’s recall remedy to ensure that it adequately addresses the safety defect. A true remedy should involve replacement of the defective engine components, not just an oil change, or an immediate buy back of my automobile by the company so I can purchase another safer vehicle. My family and I do not feel safe driving this vehicle, and the manufacturer’s current approach does not eliminate the risk of catastrophic engine failure.
