GM Recalls Engine Failure: Behind the Ongoing V8 Crisis in Trucks & SUVs
General Motors is facing a major engine recall. Hundreds of thousands of trucks and SUVs with 6.2L V8 engines have been recalled due to reports of catastrophic failures, including sudden stalling and complete engine lockup while driving.
The National Highway Traffic Safety Administration has opened and expanded investigations, and the GM recalls for engine failure affect the Chevrolet Silverado, GMC Sierra, Tahoe, Yukon, and Cadillac Escalade. As complaints continue to mount, federal regulators are pressing GM for answers.

A Growing Pattern of General Motors Engine Problems
What started as scattered owner complaints about engine noise has evolved into one of the largest recall campaigns in GM’s recent history. The 6.2L V8 engine, once considered reliable in GM’s full-size truck and SUV lineup, has become the center of federal investigations and consumer frustration. Owners across the country have reported similar symptoms: unusual knocking sounds, sudden power loss, and complete engine failure requiring full replacement. The problem affects some of GM’s most popular vehicles, from work trucks to luxury SUVs, spanning multiple model years.
What GM Engines Are Being Recalled?
The primary focus involves the 6.2L V8 engine, designated as the L87. This engine powers vehicles from the 2021 through 2024 model years. Reports of 2021 Chevy Silverado 6.2 engine failure brought early attention to the problem, with similar complaints soon emerging about 2021 GMC Sierra 6.2 engine failures. The issue extends across GM’s luxury lineup, with numerous Cadillac Escalade engine problems documented by owners. The 6.2L L87 has drawn the most regulatory attention due to the volume of failure reports and severity of defects. GM vehicle engine recalls affect approximately 600,000 to 721,000 vehicles in the United States.
Why Are GM Engines Failing?
The recall cites potential manufacturing defects in connecting rods and crankshafts that may lead to engine failure, which is why GM recalls engines equipped with these faulty components. Federal regulators describe the problem as “loss of motive power due to engine failure,” tied to quality control breakdowns during production.
- Internal component failures: When connecting rods or crankshafts fail, they cause immediate damage that leaves the engine unable to run. These failures often happen suddenly.
- Manufacturing or machining defects: Manufacturing debris or improper machining created weaknesses in critical components. These defects originated with multiple suppliers and weren’t caught before installation.
- Lubrication problems leading to catastrophic damage: In some reported cases, lubrication issues may accelerate wear, increasing the risk of seizure or lockup.
- Warning signs owners report before failure: Many owners describe hearing Silverado engine noise at startup or experiencing a Suburban engine tapping sound before complete failure. Others report Escalade engine vibration or rough running that progressively worsens.
What Is the GM Vehicle Engine Failure Recall?
After federal investigators documented safety concerns related to sudden stalling, the GM recalls for engine failure require dealerships to inspect approximately 600,000 vehicles. Dealers will examine the engine’s internal components and replace the entire engine if defects are found. Vehicles that pass inspection will receive an oil system upgrade that includes a new filter, higher-viscosity oil, and a new filler cap.
Real-World Symptoms Owners Are Reporting
Before engines fail completely, owners often notice warning signs. Many describe hearing knocking or tapping noises from under the hood, particularly during cold starts or acceleration. Others experience sudden drops in power while driving, where the vehicle struggles to maintain speed. Some owners report their engine seizing up entirely, leaving them stranded. Rough acceleration and unusual vibrations are also common complaints; these symptoms can appear gradually over weeks or suddenly within days. Owners who have experienced Silverado engine power loss or a Tahoe engine locking up describe how quickly a minor issue can escalate to complete failure.
What GM Owners Should Do If They’re Affected
If you own a 2021–2024 GM vehicle with a 6.2L V8 engine, check whether your vehicle is included in the recall by contacting your dealership or visiting the NHTSA website with your VIN. Document any symptoms you experience, keeping records of unusual noises, performance issues, and warning lights.
Schedule an inspection with your dealer as soon as possible; recall repairs are performed at no cost, and warranty protections may cover related issues. If your vehicle has required multiple repairs for the same problem or has been out of service for extended periods, you may have rights under lemon law.

Time is of the essence; as the vehicle gets older and miles increase, leverage is lost and the case can be harder to achieve a satisfactory result.

Why This GM Engine Recall Story Isn’t Over
Federal regulators are still reviewing whether GM’s fix adequately addresses the problem. Some owners have reported continued issues after receiving repairs, which could lead to expanded recalls. The investigation remains open.
