Steering / Gear Box (Other Than Rack and Pinion)
Defect, in the NHTSA record
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, in the NHTSA record
A loose steering gearbox can cause a loss of steering control, increasing the risk of a crash.
Remedy, in the NHTSA record
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.

Service Brakes
Defect, in the NHTSA record
Proterra, Inc. (Proterra) is recalling certain 2015-2018 Catalyst 40 buses equipped with an optional tow fitting and airline that allows a tow truck to operate the rear brakes on the vehicle. The mesh cap covering the airline for the tow fitting can be clogged with road debris in inclement weather, possibly resulting in a build up of air pressure in the rear brake system.
Consequence, in the NHTSA record
A build up of air pressure can cause the brakes to drag and possibly overheat, increasing the risk of fire.
Remedy, in the NHTSA record
Proterra will notify owners, and dealers will install an additional shield to the tow fitting that protects the mesh cap, free of charge. The recall began June 4, 2019. Owners may contact Proterra customer service at 1-864-438-0000.
Report filed by Proterra Inc.. Owner notification date in the NHTSA record: 4 Jun 2019.

Suspension / Front
Defect, in the NHTSA record
Proterra Inc., (Proterra) is recalling certain 2015-2018 Catalyst 40 and 35 transit buses. The affected vehicles are equipped with a four point height control system that may cause a load imbalance, overloading the front tires.
Consequence, in the NHTSA record
An overloaded front tire may fail unexpectedly, increasing the risk of crash.
Remedy, in the NHTSA record

Report filed by Proterra Inc.. Owner notification date in the NHTSA record: 26 Mar 2019.

Service Brakes, Air / Supply / Reservoir/Tank
Defect, in the NHTSA record
Proterra Inc., (Proterra) is recalling certain 2015-2018 Catalyst 40 transit buses. The affected vehicles lack a Graham White air brake supply reservoir, possibly resulting in long term moisture build up in the air brake system. As a result, these vehicles fail to comply with Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."
Consequence, in the NHTSA record
Built-up of moisture in the air brake system may lead to brake failure, increasing the risk of crash.
Remedy, in the NHTSA record
Proterra will notify owners, and dealers will install a supply reservoir with a drain between the air dryer and the air supply manifold, free of charge. The recall is expected to begin March 28, 2019. Owners may contact Proterra customer service at 1-864-438-0000.
Report filed by Proterra Inc.. Owner notification date in the NHTSA record: 21 Mar 2019.

Equipment / Other / Labels
Defect, in the NHTSA record

Consequence, in the NHTSA record
If the tire pressure is understated, an underinflated tire may result in an increased risk of tire failure, increasing the risk of a crash.

Service Brakes, Air / Disc / Caliper
Defect, in the NHTSA record
Proterra is recalling certain 2016-2017 Proterra Catalyst 40 transit buses equipped with axles with radial air disk brakes. Surface roughness of a guide pin in the radial brake calipers may cause the brake carriage guide pin support bolt to break.
Consequence, in the NHTSA record
Breakage of the guide pin can cause loss of braking ability or loss of tire pressure, increasing the risk of a crash.
Remedy, in the NHTSA record
Proterra will notify owners and have them replace the calipers on the affected axles, free of charge. Owners may contact Proterra customer service at 1-864-438-0000.
