Summary:
- The National Highway Traffic Safety Administration (NHTSA) is investigating nearly 900,000 General Motors (GM) trucks and SUVs over potential engine failures.
- The investigation focuses on 2019-2022 Chevrolet Silverado and GMC Sierra 1500 pickup trucks, as well as 2021-2022 Chevrolet Tahoe and GMC Yukon SUVs.
