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