Summary
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
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.
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.

Vehicles covered

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Has your Proterra been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Proterra dealer can also check your VIN. Recall repairs are free.
