The problem with this vehicle is that the skid control ECU that is part of the brake actuator assembly can incorrectly detect too much current flowing to the electronic parking brake actuator. The system then enters a failsafe mode which prevents the driver from applying or releasing the parking brake. If this occurs, the multi-information display displays a warning: “Parking Brake Faulty, Visit Your Dealer.”

Not having a working parking brake is a violation of Federal Motor Vehicle Safety Standard, so Toyota had to improve it.

To solve the problem, Toyota and Lexus dealers will update the software for the Skid Control ECU. The company will notify affected owners by mail no later than October 31.

According to the chronology of defects, Toyota received reports of owners unable to release the electronic parking brake. In late January 2022, the automaker and Bosch, which supplies the brake actuator system, began an investigation into the problem. Bosch found that instantaneous voltage gaps could occur during these ECU self-diagnostic checks.

From late July to mid-August, Toyota tested actual vehicles to confirm what Bosch research found and verify the problem. The automaker decided to make a recall to fix this problem.

Specifically, the affected Tundra has a production date from November 2, 2021 to August 23, 2022. The NX250 is from May 28, 2021 to August 22, 2022. The NX350 example has an assembly period from April 8, 2021 to August 22, 2022.
