Steering: gear box (other than rack and pinion)Reported February 28, 2022 · 724 vehicles affected

What is wrong: 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.
Remedy: 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.

Recall number 22V114000 · Recall details

Service brakesReported April 9, 2019 · 39 vehicles affected

What is wrong: 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.
Remedy: 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.

TiresReported January 30, 2019 · 310 vehicles affected

What is wrong: 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.
Remedy: Proterra will notify owners, and dealers will convert the current four point ride height system into a three point system to prevent the front tires from being overloaded, free of charge. The recall began March 26, 2019. Owners may contact Proterra customer service at 1‑864‑438‑0000.

Recall number 19V062000 · Recall details

Equipment: other: labelsReported January 16, 2019 · 184 vehicles affected

What is wrong: 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.
Remedy: 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.
