Recalls- Electrical traction battery. Recall 22V887000 affects 300 vehicles from 2017-2019. Liquid may leak into the battery pack enclosure increasing fire risk. Proterra will update software, inspect, and replace the battery pack at no cost.
- Steering gear box. Recall 22V114000 involves 724 vehicles from 2017-2022. Insufficient adhesive may loosen bolts securing the steering gearbox, risking loss of steering control. Dealers will install mechanical fasteners, new bolts, and torque plates as needed.
- Glass roof hatch. Recall 19V460000 affects 21 vehicles from 2018-2019. Tempered glass roof hatches may shatter due to temperature and vibration stresses, risking passenger injury. Replacement hatch lids will be provided free of charge.
- Air brakes swivel valve. Recall 19V402000 covers 147 vehicles from 2017-2018. Swivel valves may fail to protect the air brake system from air leaks, potentially causing brake failure and unintended safety brake application. The defective valve will be replaced with a check valve.
- Air brake supply reservoir. Recall 19V061000 affects 55 vehicles from 2015-2018. Some buses lack an air brake supply reservoir, possibly causing moisture buildup and brake failure. Dealers will install a supply reservoir with a drain.
- Rear service brakes. Recall 19V283000 involves 39 vehicles from 2015-2018. Debris can clog the mesh cap covering the tow fitting airline, causing air pressure build-up, brake drag, and increased fire risk. An additional shield will be installed to protect the mesh cap.
- Steering gear box adhesive. Recall 20V664000 affects 5 vehicles from 2018-2020. Missing or insufficient plexus adhesive may loosen steering box bolts, risking crash or injury. Dealers will inspect and repair adhesive and mounting bolts.
- Certification label. Recall 19V034000 covers 184 vehicles from 2015-2018. Certification labels may list incorrect axle weight ratings or tire pressures, increasing tire failure risk. Labels will be replaced with correct information.
- Tires overload risk. Recall 19V062000 impacts 310 vehicles from 2015-2018. A four point height control system may cause front tire overload and unexpected tire failure. Dealers will convert to a three point system to prevent overload.
- Front suspension system. Associated with recall 19V062000 on 310 vehicles from 2015-2018. The four point height control system creates a load imbalance risking tire failure. The suspension will be modified to a three point system free of charge.
Owners facing repeated repairs, safety defects, or unresolved recall issues with buses covered by these recalls may have rights under their state’s lemon law. They should review their options for protection and possible remedies.

STEERING:GEAR BOX (OTHER THAN RACK AND PINION)
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.
Risk: A loose steering gearbox can cause a loss of steering control, increasing the risk of a crash.
2018 PROTERRA CATALYST
300 vehicles affected
ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY
Proterra Operation Company, Inc. (Proterra) is recalling certain 2017-2019 Catalyst transit buses. One or more battery packs may allow liquid to leak into and accumulate in the battery pack enclosure.
Risk: The accumulation of liquid inside the battery pack enclosure increases the risk of a fire.
2018 PROTERRA CATALYST
5 vehicles affected
STEERING:GEAR BOX (OTHER THAN RACK AND PINION)
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.
2018 PROTERRA CATALYST
39 vehicles affected
SERVICE BRAKES
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.
Risk: A build up of air pressure can cause the brakes to drag and possibly overheat, increasing the risk of fire.
2018 PROTERRA CATALYST
55 vehicles affected
SERVICE BRAKES, AIR:SUPPLY:RESERVOIR/TANK
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."
Risk: Built-up of moisture in the air brake system may lead to brake failure, increasing the risk of crash.
2018 PROTERRA CATALYST
147 vehicles affected
SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE
Proterra, Inc. (Proterra) is recalling certain 2017-2018 Catalyst buses. The vehicles are equipped with swivel valves that may insufficiently protect the air brake system from an air leak between the service reservoir and the source of air pressure. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."
Risk: If the swivel valves are unable to protect the air brake system against loss of air pressure, this may lead to service brake failure and the possibility for the uncontrolled application of the safety brake. Either condition increases the risk of crash.
2018 PROTERRA CATALYST
21 vehicles affected
STRUCTURE:EMERGENCY:ESCAPE/EGRESS/EXIT
Proterra, Inc. (Proterra) is recalling certain 2018-2019 Catalyst buses equipped with a certain batch of glass roof hatches. Temperature and vibration stresses may cause the tempered glass roof hatch to shatter.
Risk: If the tempered glass roof hatch shatters, glass fragments may fall onto passengers, increasing the risk of an injury.
2018 PROTERRA CATALYST
310 vehicles affected
SUSPENSION:FRONT
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.
Risk: An overloaded front tire may fail unexpectedly, increasing the risk of crash.
2018 PROTERRA CATALYST
184 vehicles affected
EQUIPMENT:OTHER:LABELS
Proterra, Inc is recalling certain 2015-2018 Catalyst 40, and Catalyst 35 buses. The certification label may list an incorrect gross front axle weight rating and/or incorrect tire pressures. As such, these vehicles fail to comply with the requirements of 49 CFR Part 567, "Certification."
Risk: If the tire pressure is understated, an underinflated tire may result in an increased risk of tire failure, increasing the risk of a crash.
