Pre Purchase Inspection for 2024 Chevy Tahoe

NHTSA recall 24V-797 covers certain 2021 Tahoes with the diesel engine. A worn transmission control valve can lock up the rear wheels. Dealers install new transmission software, and GM special coverage N242454441 covers repair of a bad valve found by that software for 15 years or 150,000 miles from the in service date. Recall 26V-085 covers certain 2022 Tahoes with the 10-speed and electronic shifter (ETRS), with the same kind of software fix, and special coverage N252536751 adds the same 15 years or 150,000 miles. GM lists harsh shifting, a service engine soon message, reduced power or code P0747 as signs of the worn valve.

WE CHECK We check the VIN for both recalls, scan the transmission for P0747 and other codes, and road test for harsh or odd shifts.
