Proterra is recalling 386 transit buses, including 2020-2021 Catalyst models and 2019-2022 ZX5 models, because the parking brake may engage while the vehicle is in motion. This occurs due to air pressure issues in a shared exhaust system used by both the ride height controls and the parking brake valve. Proterra will install a redesigned air circuit to fix this issue at no cost to vehicle owners.
If the parking brake engages unexpectedly while the bus is moving, it can cause a sudden loss of vehicle control or a sudden stop, significantly increasing the risk of a crash.
