A transistor inside the inverter may overheat and fail, which can result in a loss of power steering and drive power.

Consequence: A loss of power steering and/or drive power increases the risk of a crash.

Remedy: Dealers will replace the inverter, free of charge. Owner notification letters were mailed December 16, 2023. Owners may contact Proterra customer service at 1-864-438-0000.

Defect: Proterra Operating Company, Inc. (Proterra) is recalling certain 2020-2022 35" Catalyst, 35" ZX5, and 40" ZX5 vehicles. The windshield wiper motors may operate intermittently or may fail to operate. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 104, "Windshield Wiping and Washing Systems."

Consequence: Inoperative windshield wipers can reduce visibility in certain driving conditions, increasing the risk of a crash.

Remedy: Dealers will replace the wiper motors, free of charge. Owner notification letters were mailed April 3, 2023. Owners may contact Proterra customer service at 1-864-438-0000.

Defect: Proterra Operating Company, Inc. (Proterra) is recalling certain 2020-2021 Catalyst and 2019-2022 ZX5 transit buses. Back pressure in the shared air exhaust for the pneumatic ride height system and parking brake control valve may engage the parking brake while the vehicle is in motion.

Consequence: Unintentional engagement of the parking brake increases the risk of a crash.

Remedy: Proterra will install a redesigned air circuit, free of charge. Owner notification letters were mailed on December 21, 2022. Owners may contact Proterra's 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.

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

Notes on this record

  • Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
  • System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
  • Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
  • A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
  • NHTSA's complaints API and bulk file list no complaint for this make, model and model year in this data build.
