While towing a light trailer (~3,000 lbs) through the mountains on an interstate, my 2022 Suburban with the 6.2 engine suddenly got hot and shut off. There were no symptoms of the engine having any issues, it had been running well the whole trip. The temperature gauge went from normal to very hot in a very short time. I was not able to get it to a pull-off area and was stranded partially in the right lane of the interstate with several collision close calls. This problem was later determined by the dealer to be the common crank bearing issue for this model engine.

ELECTRICAL SYSTEM
While driving, the digital driver/instrument display behind the steering wheel went completely black, but the engine continued running and the radio remained on. The vehicle was stopped, turned off and restarted and the display screen came back on. This didn't effect the drivability of the vehicle. In some of the research I've found the cause might be an instrument-cluster software problem or an "Instrument Cluster Missing Graphics Processor". The recommended remedy would be to replace the instrument cluster. There is also one instance where the dealer reportedly determined that the instrument panel control module needed to be reset versus repaired which would not permanently resolve the issue.

The contact owns a 2023 Chevrolet Suburban. While the contact’s husband was driving 70-75 MPH and depressing the accelerator pedal, the vehicle failed to respond, but the RPMs became elevated. The driver shifted transmission into neutral(N), coasted to the side of the road, and the vehicle stalled. A message to “Start Vehicle” was displayed; however, while on the side of the road, the vehicle failed to turn off. The driver was able to shift into park(P) and had the vehicle towed to the dealer, where the transmission failed to shift out of park(P). The dealer determined that a spark plug was burned. The spark plug was replaced; however, before returning the vehicle, the new spark plug was also burned. The dealer then diagnosed the vehicle with engine failur. The dealer informed the manufacturer of the safety issue. The failure mileage was approximately 42,600.

Sudden Loss of Power & Shaking: The misfire itself causes a drastic drop in acceleration. If you are merging onto a highway or trying to pass another vehicle, the sudden loss of power can leave you stranded in the path of oncoming traffic. No Stability Assistance: Because StabiliTrak and Traction Control are automatically disabled, the vehicle loses its ability to correct for skids, fishtailing, or hydroplaning. In rain, snow, or emergency swerving maneuvers, a heavy SUV becomes much harder to control. "Limp Mode" (Reduced Power): To prevent the unburned fuel from a misfire from destroying the expensive catalytic converters, the vehicle may force itself into a "Reduced Engine Power" or "Limp" mode. This limits your top speed (often to around 30 mph), which is highly dangerous if you are in the fast lane of a highway. Violent Transmission Shifting: To protect the drivetrain from the erratic power dips of a misfiring engine, the vehicle's computer will maximize transmission fluid pressure. This causes the Suburban to shift gears incredibly hard, which and feel as though the transmission is exploding

WHEELS
Subject: Formal Safety Complaint—Cracked 22-Inch Polished Aluminum Wheels on 2024 Chevrolet Suburban To Whom It May Concern: I am submitting a formal complaint concerning repeated failures of the original 22-inch polished aluminum wheels installed on my 2024 Chevrolet Suburban, which I purchased new. Two wheels have cracked without any known impact, collision, road-hazard event, or other incident that would reasonably explain the damage. The first wheel cracked at approximately 25,000 miles. Tire pressure began dropping unexpectedly and ultimately fell to zero. The wheel was inspected and replaced by a dealership in Cincinnati. A second wheel later cracked and caused another sudden loss of tire pressure without warning. During that incident, I experienced difficulty maintaining steering control, creating a serious risk of a crash and injury. The second wheel was inspected and replaced by Tire Discounters in Lebanon, Ohio. The recurrence of substantially similar failures raises concern that the wheels may contain a material, manufacturing, or design defect. Aluminum wheels should not crack during normal operation in the absence of impact damage. A sudden loss of tire pressure, especially while the vehicle is moving, presents an unacceptable safety risk to the vehicle’s occupants and other road users. I respectfully request that Chevrolet and General Motors promptly: 1. Investigate these wheel failures as a potential safety-related defect; 2. Arrange for a thorough inspection of all remaining wheels on the vehicle; 3. Replace any affected wheels at no cost to me and review reimbursement for related expenses already incurred; 4. Confirm whether similar complaints, technical service bulletins, special coverage programs, or recalls have been identified; and 5. Provide a written response explaining the findings and proposed corrective action. I can provide the vehicle identification number, purchase documentation, mileage records, photographs, inspection findings, r

ENGINE
While driving down a two-lane blacktop road at 70 MPH (the posted speed limit) the engine, a 6.2 L L87 with a little over 15,000 miles, grenaded and seized. At the time I recall a warning message that said something like "engine shutdown". Fortunately the electronic transmission self-shifted into neutral so the car could coast to a stop. Had it not done this a loss of control would have been likely at this speed. The vehicle was towed to the local Chevrolet dealer in Bozeman, Montana (Resseler Chevrolet) where it was confirmed the next day the engine had seized. The dealer is currently replacing the seized engine with a replacement long block. The dealership currently has the engine and is planning to ship it back to Chevrolet or GM for tear down and inspection. They are also replacing the radiator and all coolant hoses as a precaution. Two weeks prior I took the vehicle to the same Chevrolet dealer complaining that on one day the engine shut off four times within 1 mile. Each time it displayed a warning message that said "restart engine", which it did each time. I also complained about a ticking noise that began in the engine at 12,000 mile. The dealer reported that the engine sounded fine and that they could not reproduce the engine shutting off on its own. This engine was NOT part of the large L87 recall. At time of purchase I was told by the selling dealer (Kendall Chevrolet in Maryville, Washington) and the local dealer (Resseler) that the engine was assembled after assembly line procedure were put in place to avoid the same issues as the recall engine. I've been and engineer for 46 years. The problem with this engine is not the assembly line, it is the never before used tight moving component tolerances and the water thin oil demanded by the manufacturer. The design shortcomings are compounded by systems such as cylinder deactivation and auto stop that significantly acceleration engine component wear.

Dear Chevrolet Customer Assistance, I am writing to formally report a serious safety incident involving my 2023 Chevrolet Suburban and to request an investigation by General Motors. My vehicle unexpectedly locked while the key fob was still inside the vehicle. Most concerning, my baby was also inside the vehicle at the time. I was unable to regain access to the Suburban, and because my baby was trapped inside, I had no reasonable option but to break a window to gain immediate access to her. This was an extremely serious and frightening situation. My primary concern is understanding how a 2023 Chevrolet Suburban equipped with a keyless entry system was able to lock while the key fob remained inside the vehicle. I am requesting that Chevrolet/General Motors: 1. Open a formal safety case regarding this incident. 2. Investigate why the vehicle locked despite the key fob being inside. 3. Have the vehicle’s keyless entry, passive locking system, key-detection components, software, and related systems inspected for a malfunction. 4. Determine whether there are any applicable recalls, technical service bulletins, software updates, or previously reported incidents involving similar circumstances. 5. Reimburse me for the cost of the broken window and related repairs, as the window had to be broken solely because immediate emergency access to my baby was necessary. I do not want this incident documented simply as a customer accidentally locking keys inside a vehicle. The key fob was inside the Suburban when the vehicle locked, and an infant was trapped inside as a result. I am asking that this be documented and investigated specifically as a potential vehicle safety or key-detection system issue. I can provide my VIN, photographs of the damage, repair invoices, key fob information, dealership inspection records, and any other documentation necessary for your investigation. Please provide me with a GM case number and written confirmation that this incident has been form

I am filing this complaint regarding a serious engine and safety issue with my 2021 Chevrolet Suburban equipped with the GM 6.2L engine, with approximately 45,500 miles. The vehicle has developed a noticeable and abnormal shaking/vibration coming from the engine. At the same time, the vehicle experiences a significant loss of power, at times becoming so severe that the engine feels as though it is going to shut off. This is a serious safety concern. A sudden loss of engine power could occur while driving in traffic, accelerating, merging, or traveling at higher speeds. The vehicle may become unable to accelerate properly or could potentially stall, creating a significant risk of a collision. I am concerned that this issue may be related to a defect affecting GM's 6.2L engines. The fact that this is occurring at approximately 45,500 miles is particularly concerning, as an engine should not experience this type of severe shaking and loss of power under normal operating conditions. I respectfully request that NHTSA investigate this issue and determine whether there is a safety-related defect affecting the GM 6.2L engine used in the 2021 Chevrolet Suburban and other GM vehicles. I am reporting this because I believe the sudden loss of power and potential for the engine to shut off could endanger the occupants of the vehicle as well as other motorists

ENGINE
The vehicle experienced an initial incident of significant engine power loss while traveling at highway speeds approximately two weeks prior to the eventual complete engine failure. During that incident, the vehicle unexpectedly lost engine power while traveling at speeds exceeding 65 mph. On Thursday, September 3, 2026, a second incident occurred within approximately one-half mile of leaving my residence. The vehicle again experienced a significant loss of engine power. I had already notified the dealership of the this occurrence and had a scheduled appointment for repairs the following day. I was attempting to drive the vehicle to the dealership as planned. Shortly after leaving my neighborhood, I stopped at a nearby gas station after the vehicle displayed a "Low Oil Pressure" warning on the dashboard. I also subsequently received an email notification from OnStar identifying diagnostic trouble code (DTC) P0016. The vehicle was then driven again and subsequently experienced a catastrophic and complete loss of engine power while traveling at highway speeds above 65 mph. Following this failure, the engine would not turn over or crank and the vehicle could not be restarted. The sequence of events is significant because the vehicle had previously experienced engine power loss at highway speeds, the dealership had been notified of the initial incident, and the vehicle was being driven to the dealership for its scheduled repair appointment when the second power-loss event occurred. The vehicle subsequently suffered complete engine failure. I am documenting these events, including the dates, circumstances, dashboard warning, OnStar diagnostic notification, and sequence of failures, for purposes of establishing the history of the vehicle's mechanical problem and the circumstances leading to the catastrophic engine failure.

Complete engine failure on 2023 Chevrolet Suburban 6.2L. On October 31, 2024 while on the interstate. The truck shut off twice with no warning. I was able to make it to the side of the interstate twice to restart. The truck was taken to Serpentini Chevrolet and they stated no issues were found and send the vehicle back on the road. On December 13,2024 while on a state route, speed limit 55, 12,231 miles the Suburban abruptly slowed down and violently started to shake and knock. I pulled off to the side of the state route and waited approx 2 hours for the vehicle to be towed. The vehicle was towed to Serpentini Chevrolet and they stated the engine was blown and needed replaced. The vehicle was at the dealership until February 13, 2025 when the engine was replaced. The recall was released in April 2025 at which time the vehicle was taken in for the oil change “repair”. The truck now has 20,200 miles and is lacking power and starting to shake when accelerating from 0-50mph. I will be scheduling additional service in the coming week. While going through the blown engine, GM stopped responding to emails, did not compensate for months of payments I incurred while they had the vehicle and they are still selling unsafe vehicle.

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.

This vehicle has been towed approximately 7 times in the last year. For all instances in [XXX] in 2025, the dealership told us there were no issues. The completed the recall on the L87 and it 'passed'. The dealership then updated the oil to 40W and sent us on our way. We continued to have issues, but it was deemed to be the transmission. We had that relaced earlier this year. On XXX the car shut off again while driving on a highway. Upon this dealership taking a look at it, they have determined the engine has locked up for reasons under the L87 recall. I wanted to note this with the NHTSA as the recall was completed, but later found that it was not actually corrected through their guidance within the recall.
