Proterra Inc. (Proterra) is recalling certain 2018-2020 35 foot and 40 foot Catalyst buses. Lack of plexus adhesive between the torque plate and the vehicle chassis may cause the bolts securing the steering gear box to loosen.
An unsecured steering gear box could cause the driver to lose the ability to steer the vehicle, increasing the risk of crash or injury.
Proterra will notify owners, and dealers will inspect the steering gear mounting bolts and the plexus adhesive layer between the torque plate and the chassis. If the plexus adhesive layer is missing or insufficient, the components will be repaired, free of charge. The recall began December 10, 2020. Owners may contact Proterra customer service at 1-864-438-0000. Proterra's number for this recall is SC-20-154.
