Complete loss of power assist steering with multiple safety codes causing loss of vehicle control. Was able to pull over in parking lot to get vehicle off the road. Near impossible to steer when incident happened. Frightening experience. As other complaints have noted frame to body ground strap located behind passenger front tire severely corroded and causing loss of ground contact. No service center open so had to be towed home. Vehicle only has 27,000mi. This has been reported frequently and should be a safety recall as very dangerous.

This 2019 Silverado pickup truck lurched forward on 2 different occasions. The first time it lurched forward, it was in a parking lot and no damage was done to the truck or any other vehicle. The second time our 2019 Silverado pickup truck lurched forward I was turning around at a farm. The truck hit a wooden building on the farm and did damage to it and our truck did damage the front end of the truck to the tune of $3,474.00. If someone was in front of the truck, they would have been killed or seriously injured. We have been very careful with the truck ever since. We could pull it into our garage and it could lurch forward and go through the garage wall.

While traveling on the [XXX] at 70mph the truck started making a loud noise and started feeling like all tires were flat. Getting off the road the routors were very hot. Getting back on the interstate to get to an exit, a message appeared that said brake failure. There were no brakes when pedal was applied. It was towed to the Integrity Chevrolet in Chattanooga, Tn. A case was opened with General Motors #[XXX]. GMC reported to us that the truck which we bought with 5900 miles (driven by a salesman), had had the brakes reprogrammed 4 times which we were unaware of. They reprogrammed the brakes, put on new brake pads, milled the router and replaced the brake fluid, informing us this was needed, charging us $1210. GMC refused to pay because the dealership said it was normal wear and tear. Truck has 38,000 miles. Brake pads showed 62% front and 78% back life. We have emails as documentation. I was unable to upload but can forward if email address is provided. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) . The contact stated this is the 5th time the brake system has been reprogrammed, (4xs before we purchased it unaware of this and on March 11th).

I started vehicle. Everything seemed fine. Drove 2 blocks and all eletricals started acting up. Lights flashing all warning lights went off. Service brakes, Service parking brake, service ECM, etc. Motor started to bog down and major knocking from engine. Took to GMC dealership. They found issues with lifters and had to replace all lifters and camshaft. Also replaced faulty brake sensor. Get truck back and oil cooler hose or line came off and was leaking oil. 1 week after repairs.

Opened Oct 23, 2025 · No close date supplied
Status: open (inferred from source dates) · Engine; Engine And Engine Cooling:engine:hard Parts Internal/mechanical
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. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.

PE25001 · Loss Of Motive Power Due To Engine Failure
Opened Jan 16, 2025 · Closed Oct 23, 2025
Status: closed (inferred from source dates) · Engine; Engine And Engine Cooling:engine:hard Parts Internal/mechanical
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. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).
