Problem 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. Risk An unsecured steering gear box could cause the driver to lose the ability to steer the vehicle, increasing the risk of crash or injury. Fix 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.

Two numbers, one recall

Every safety recall carries two identifiers. SC-20-154 is the number Proterra assigned in its own system: it is what appears on the owner letter, on the dealer’s service screen and on the repair order. 20V664000 is the number NHTSA filed the same recall under when the manufacturer reported it, and it is the one every federal record, this site included, is keyed on.

The repair is free by federal law for vehicles up to fifteen years old. Whether one particular vehicle is included is settled by its VIN against the manufacturer’s build list, not by its model year.

Check one specific vehicle

Both lookups check a VIN against the manufacturer’s own list and say whether the repair is still outstanding on that vehicle.
