STEERING:GEAR BOX (OTHER THAN RACK AND PINION)
Issued by Proterra, Inc. · Reported Feb 28, 2022 · 724 vehicles affected
What's wrong
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.
Consequence
A loose steering gearbox can cause a loss of steering control, increasing the risk of a crash.
Remedy
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.
