While traveling in bumper to bumper highway traffic in my 2022 Chevrolet Silverado RST, I attempted to accelerate and the vehicle suddenly malfunctioned. I experienced sever loss/restriction of propulsion and the vehicle would not respond normally to accelerator input. I was able to maneuver toward the shoulder of the road while avoiding a major multi-car pile up involving innocent motorists. When I attempted to stop, I did not have normal braking ability and was unable to stop in the manner I expected. I had to use the shoulder of the highway to slow the truck down until I could come to a complete stop. This created an immediate risk of serious or fatal collision on the highway, and as I maneuvered the truck out of traffic to the side of the road. Had I been unable to reach the shoulder of the road, I could have been struck by surrounding traffic. Had this failure occured un an urban area or at an intersection, near pedestrians, or at a school bus stop- I could have seriously injured or killed people or myself. After I was able to come to a complete stop. I shut it off and turned it back on, then the truck read there was no gas left (I had a 1/2 tank). This incident is not isolated electronic glitch, I have experienced electrical malfunctions including the truck failing to start, unlocking, responding at all. This all occured after an engine replacement due to a recall. I am concerned that there are unresolved electrical and power-distribution, communication-network, propulsion or braking issues that presents a serious safety risk to myself and others. My concern is that if this malfunction occurred on my drive to work in the city, around pedestrians- it could have resulted in multiple fatalities.

The pads were not worn much at all but brake pad clips were broken on both sides of rear brakes. Rotors were rusted which looked as if rear brakes have not been contacting rotors.

When stalled, truck lost its ability to steer and break causing the truck to drive off the road and only stopped due to the truck rolling to a stop off-road. Luckily nothing was seriously damaged and it was a rural area with minimal traffic and flat grass lands on the side of the highway.

Went to Freeport Chevy dealer and changed oil, when I bought the car pre-approved but the when I went for the service they said no oil was changed since the car was new. And I have been paying for all the warranty and extended service but they said all oil change and others will cost approx $3200. They changed the oil but I have been seeing on the Chevy app filter was never changed and the car didn’t feel same after the service.

Valve body failed in Dec. 2024 and they replaced it. Valve body failed again in April 2025, they replaced it with new. Valve body failed again in Oct 2025, they said they will not replace it. The brakes locked up for a few seconds making a loud noise, it would not go in reverse which i showed the mechanic all three times, and it would not go over 35mph. they told me the new transmission they put in it in April of 2025, was not warrantied. This has been an on going issue since the original recall, and they refuse to fix it correctly. You will see from the documents, it has been in the shop 6 times in 10 months. now it sits in my yard because I don't want to get in a accident if it goes out while I'm driving. I can not go south for the winter like we usually do because of the truck. Chevy doesn't seem to want to fix the on going issue which was a recall.

While towing a camping trailer, the brakes for the trailer kept issuing a warning saying "connected" then "not connected - check trailer brake wiring". Then "trailer brake not connected". After a while the brake system stopped working entirely. The 30 amp fuse that controls the trailer braking system blows out. This fuse is not a common fuse and not available at some auto parts stores (not really convenient while towing away from home). Evidently there is a problem with the brake control module that is factory installed. The module does not like the charging system on the trailer battery. I have spent hundreds of dollars and many hours in different shops trying to trace down this problem. It is very unsafe to have the trailer brakes not work while driving. This faulty module needs to be recalled. Part # 23306694

While driving, speed can vary, but yesterday we were going almost 50, and the transmission or brakes lock up which causes the back axel to lock up and the tire squeal, similar to slamming on the brakes. It caused my truck to sway side to side and scare the hell out of my son. Definitely not safe. The local dealer says it is a stuck valve or something. It has caused the engine light to come on multiple times, but will go off after 24 hours or so. But it keeps occurring. Happened 3 times on 7-8-25. Give a whiplash feeling to the body as well.

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.
