Proterra, Inc. "Proterra" is recalling certain 2017-2019 35 foot Catalyst E2, 2017-2019 40 foot E2, 2020-2021 35 foot RR, 2019-2020 40 foot RR, 2019-2022 40 foot ZX5, and 2020-2022 35 foot ZX5 buses. The plexus adhesive between the torque limiter plate and the bus body may be insufficient, causing the bolts that secure the steering gearbox to loosen.
A loose steering gearbox can cause a loss of steering control, increasing the risk of a crash.
Dealers will install a mechanical fastener and new bolts on the steering gearbox, and install a new torque plate, as necessary, free of charge. Owner notification letters were mailed October 7, 2022. Owners may contact Proterra's customer service at 1-864-438-0000.
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.
