U.S. auto safety regulators have launched an investigation into complaints that certain V8-powered General Motors cars, including the best-selling Silverado, can seize up without warning.
The National Highway Transportation Safety Administration announced Thursday that it has received 39 complaints from users of GM vehicles equipped with L87 V8 engines and is investigating an estimated 877,710 vehicles.
NHTSA said the complainants reported “no prior detection of engine failure,” which could lead to an increased risk of crashes resulting in personal injury or property damage. Regulators say bearing failure can cause engine seizure and connecting rod damage to the engine block.
Vehicles targeted in the preliminary investigation include 2019-2024 Chevrolet Silverado 1500s. 2021-2024 Chevrolet Tahoe. 2021-2024 Chevrolet Suburban. 2019-2024 GMC Sierra 1500. 2021-2024 GMC Yukon. 2021-2024 GMC Yukon XL; 2021-2024 Cadillac Escalade. and 2021-2024 Cadillac Escalade ESV.
General Motors will be the U.S. leader in auto sales in 2024, with sales increasing 4.3% that year, marking its best performance since 2019. The company's Silverado pickup truck was the second best-selling vehicle in the United States last year.
