WASHINGTON — Toyota is recalling nearly 400,000 vehicles because the rearview camera may not display when backing up, increasing the risk of a crash, federal traffic safety regulators said.

Included in the recall are 2022-2025 Toyota Tundras and Tundra hybrids and 2023-2025 Sequoia hybrids. The number of automobiles in the recall total 393,838, with the non-hybrid Tundra making up more than half of them.

The camera display malfunction is caused by a software problem, which will be fixed with an update by dealerships free of charge.

Owner notification letters are expected to be mailed on Nov. 16. Owners can contact Toyota’s customer service at 1-800-331-4331. The numbers for the recall are 25TB10 and 25TA10.

Owners may also contact the National Highway Traffic Safety Administration vehicle safety Hotline at 1-888-327-4236 (TTY 1-888-275-9171), or go to www.nhtsa.gov.
