Overview

2021 Chevrolet Tahoe

The 2021 Chevrolet Tahoe offers substantial presence and capability, but used buyers should proceed with caution. Its 6.2L V8 engine, while powerful, is linked to a notable number of engine and fuel system complaints, including unexpected stalling. With 23 recalls and 488 complaints logged with NHTSA, particularly concerning the powertrain and fuel systems, diligent pre-purchase inspection is paramount. Safety ratings are generally strong, with a 5-star side crash rating, though rollover protection is rated lower.
