General Motor Vehicles Alleged Crankshaft Defect May Lead to Engine Failure

Shub & Johns launches investigation into General Motors after consumers report issues with the crankshaft in some vehicles, potentially leading to engine failure. Consumers take to online forums to voice their concerns about this alleged defect that could require a full engine replacement.

Owners of General Motors vehicles equipped with a 6.2L V8 engines may be concerned with various engine issues that may be arising as a result of crankshaft bearing failure. Vehicles equipped with L86 and L87 variants of the motor have likely started to see these issues emerge. These vehicles include:

• 2014 and later Chevrolet Silverado
• 2014 and later GMC Sierra 
• 2015 and later Chevrolet Tahoe
• 2015 and later GMC Yukon
• 2015 and later Chevrolet Suburban 
• 2015 and later GMC Yukon XL
• 2015 and later Cadillac Escalade 
• 2015 and later Cadillac Escalade ESV 

As a result of the alleged crankshaft failure, owners and drivers of these vehicles may experience engine overheating due to increased friction, audible knocking sounds, and even full engine seizure, which can completely cause loss of power and deceleration of the vehicle. The crankshaft failure can also lead to engine oil contamination and oil flow disruption.

These issues can put consumers on the road at serious risks. From causing engine failure to sudden loss of power on the vehicle, drivers, passengers, and others on the road may be affected. Not only can this alleged defect put consumers in danger, it may also require a complete engine replacement. This is a problem General Motors either knew about or should have known before widespread sales of the vehicle.
