Plain-English summary

Proterra Inc. is recalling certain 2018-2020 35-foot and 40-foot Catalyst buses. The recall addresses a defect where a 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 a crash or injury. The recall began on December 10, 2020.

Proterra will notify owners, and dealers will inspect the steering gear mounting bolts and the plexus adhesive layer. If the adhesive layer is missing or insufficient, the components will be repaired free of charge.
