NHTSA Expands Investigation into GM 6.2L V8 Engine Recall

The National Highway Traffic Safety Administration is escalating its investigation into General Motors' 6.2-liter L87 V8 engines, according to AutoGuide.

In April, GM had recalled 721,000 vehicles produced between 2021 and 2024 over reports of engine bearing failures. But NHTSA has received an additional 1,157 complaints related to the problem that have prompted it to expand its investigation to another 286,051 vehicles from model years 2019 to 2021, as well as some 2024 vehicles not originally included.

NHTSA will carry out an engineering analysis to determine whether GM’s original recall should be expanded to include Chevrolet Silverado and GMC Sierra 1500, Chevy Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade models built between 2019 and 2024.

GM has not commented on the new investigation, but has pointed to supplier manufacturing and quality issues as reasons in the past.
