Rear camera view intermittently displays a blank or distorted image. This issue occurs almost every time when in reverse. In most occurrences, the screen will alternate between a blank screen with a warning indication and the video display several times within the same occurrence. After the video display reappears, the camera view sometimes freezes and does not display a live feed. These issues contribute to considerable risk and liability when the vehicle is in reverse. This issue is identical to a current recall on another vehicle. Please reference safety recall notice 22S06/ NHTSA Recall 22V082 for correlated information. The dealership refuses to acknowledge the issue and it has already contributed to physical damage when backing into my garage.

When connected to a trailer with trailer brakes, the driver information center displays a message check trailer brakes when I apply the brakes. After usually the 3rd brake application the driver information center displays a message-Trailer Brake Disabled. Local certified chevy dealer tested the brake components on a computer and verified it is the truck that has issues. They also stated there is no fix at this time and that Chevrolet has known about the issue. Our dealership said to drive it without them, that is irresponsible. My vehicle is available for inspection at any time. This is very dangerous and the truck should not be driven while towing a trailer. This is a continuous issue and not intermittent.

One week prior to the incident my engine had a loud ticking/knocking noise when starting up especially on a cold start, one night before thanksgiving driving to California I had my truck on cruise control 80mph when suddenly without any warning the engine shut off! My touch screen and speed gauge were still on I tried pulling over as quickly as I can with my emergency flashers on, I was almost side struck by trailers passing by me doing so! My truck got towed to the nearest Chevy dealer where I was told it was an electrical issue at first, then 3 hours after that call the service team called again telling me they have found metal engine shavings and pieces in my engine while draining my engine oil. Service team told me they contacted GM for a new engine replacement and my truck will be in their shop for a month waiting for delivery and working on my truck. All this damage because of the AFM DFM feature in V8 engines and it happening at 7,000 miles it’s unacceptable.

My 2022 Silverado is affected by a couple different electronic safety issues. The first one has to do with the trailering system. When I have trailer connected that has electronic brakes on it, the vehicle gives an error message and then shuts the break control off. When this happens the trailer does not assist the truck in breaking when the pedal is pressed. The truck has to do all the work to stop not only itself, but the weight of the trailer as well. I found this out while towing my camper that weighs approximately 7500lbs. This is very dangerous and unsafe. The GM dealership has verified this issue and gave me a bulletin that came from GM that states that they are aware of the issue and they do not no what is causing it or how to fix it. I also have issues with my smaller trailers that have no brakes. When connected, the vehicle will give me random error messages about the trailer lighting. When this happens the trailer lights flash without me pressing the brakes or using turnsignals. This also is a huge safety issue. People following me may not know if I am turning or stopping, which could lead to an accident. The dealership also confirmed this issue and they believe it may be tied to the other issue outlined in GMs bulletin. The bulletin doesn't say anything about trailer lights, so the dealership has no clue on what is causing it or how to fix it. The last issue is with the back up camera. It goes out periodically while backing up. This can lead to me hitting someone or something that I may not see in my mirrors. My vehicle is a truck and is pretty large. The backup camera is there to help in backing safety. The dealership did confirm this issue with a code in the computer, but they couldn't get it to replicate while it was in the shop so they are unable to get solution to fix it. I have to wait until it completely goes bad or GM releases a bulletin. I know I'm not the only one with this issue. It is documented on a few forums. I have a case with GM.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE.
