PARKING BRAKE
- The defect
- Proterra Operating Company, Inc. (Proterra) is recalling certain 2020-2021 Catalyst and 2019-2022 ZX5 transit buses. Back pressure in the shared air exhaust for the pneumatic ride height system and parking brake control valve may engage the parking brake while the vehicle is in motion.
- What it can cause
- Unintentional engagement of the parking brake increases the risk of a crash.
- What the dealer does
- Proterra will install a redesigned air circuit, free of charge. Owner notification letters were mailed on December 21, 2022. Owners may contact Proterra's customer service at 1-864-438-0000.
- NHTSA's note
- Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner.
Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup .

Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
