This probe covers certain 2019-2024 Chevy Silverado 1500, GMC Sierra 1500, Chevy Tahoe, Chevy Suburban, GMC Yukon and Cadillac Escalade vehicles equipped with the 6.2-liter V-8 engine aka L87.

According to a Reuters report, the NHTSA Office of Defects Investigation determined the scope and severity of the problem was high enough to take a closer look.

Federal Investigators believe a bearing failure could result in engine seizure or breading of the engine block by the connecting rod.

This failure would lead to a loss of power.

NHTSA states they have received 39 complaints and several early warning field reports from vehicle owners. These owners also said the loss of power was sudden and they had no warning signs before the engine failed.

There have been no crashes or fires reported.

GM says it will work with NHTSA during this probe.
