GM Faces Class Action Lawsuit Over Alleged L87 Engine Defects

Introduction

General Motors (GM) is under legal scrutiny following a class action lawsuit filed in Illinois, alleging that its 6.2L V8 L87 engines are prone to sudden and catastrophic failures due to defective connecting rod bearings. This issue has reportedly affected a range of GM's full-size trucks and SUVs, raising concerns about vehicle safety and reliability.​

Details of the Lawsuit

The lawsuit was initiated by James S. Powell II, an Illinois resident who purchased a new 2023 GMC Yukon Denali equipped with the L87 engine. Within a year, Powell experienced engine issues, including the illumination of the check engine light. Upon inspection, technicians discovered metal shavings in the oil and internal engine damage attributed to a failed connecting rod bearing. Although GM replaced the engine under warranty, Powell alleges that the replacement engine exhibited the same defect, prompting him to seek over $5 million in damages. ​

Vehicles Potentially Affected

The lawsuit identifies several GM models that may be equipped with the allegedly defective L87 engines:​

  • 2019–2024 Chevrolet Silverado 1500​

  • 2021–2024 Chevrolet Tahoe and Suburban

  • 2019–2024 GMC Sierra 1500​

  • 2021–2024 GMC Yukon and Yukon XL​

  • 2021–2024 Cadillac Escalade and Escalade ESV​

Owners of these vehicles have reported engine failures occurring at highway speeds, posing significant safety risks and diminishing vehicle value. ​

NHTSA Investigation

The National Highway Traffic Safety Administration (NHTSA) has launched an investigation into the L87 engine failures after receiving 39 complaints and numerous field reports. The agency estimates that over 877,000 vehicles may be affected by this issue. ​

Allegations Against GM

The lawsuit alleges that GM was aware of the bearing defect but failed to disclose the issue to consumers or initiate a recall. This lack of transparency has led to unexpected engine failures, even in vehicles with low mileage and consistent maintenance. ​

Legal Options for Affected Owners

Owners experiencing issues with their L87 engines may have legal recourse under state lemon laws or through participation in the class action lawsuit. Potential remedies include vehicle replacement, reimbursement for repair costs, or monetary compensation.​
