  3. Recall Description

    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."

    Possible Effects

    Built-up of moisture in the air brake system may lead to brake failure, increasing the risk of crash.

    Action

    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.

  4. Recall Description

    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.

    Possible Effects

    Breakage of the guide pin can cause loss of braking ability or loss of tire pressure, increasing the risk of a crash.

    Action

    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.

  5. Recall Description

    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."

    Possible Effects

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

    Action

    Proterra will notify owners, and dealers will replace the certification labels with correct information for all affected customers, free of charge. The recall began March 12, 2019. Owners may contact Proterra customer service at 1-864-438-0000.

  6. Recall Description

    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."

    Possible Effects

    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.

    Action

    Proterra will notify owners, and will replace the swivel valve with a check valve that is sufficient to protect the air brake system, free of charge. The recall began July 26, 2019. Owners may contact Proterra customer service at 1-864-438-0000.

    Notes

    Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

  7. Recall Description

    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.

    Possible Effects

    A build up of air pressure can cause the brakes to drag and possibly overheat, increasing the risk of fire.

    Action

    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.

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.

    Possible Effects

    A loose steering gearbox can cause a loss of steering control, increasing the risk of a crash.

    Action
