Proterra Catalyst Recall 19V061: Moisture in Air Brakes Could Cause Brake Failure

NHTSA campaign 19V061, reported January 29, 2019, 55 vehicles potentially affected.

What this recall means for you

Some transit buses are missing an air brake supply reservoir, which allows moisture to build up over time in the air brake system. This can lead to brake failure and raises the risk of a crash. The vehicles also do not meet federal air brake safety standard FMVSS 121.

The manufacturer will notify owners, and authorized dealers will install a supply reservoir with a drain between the air dryer and the air supply manifold. The repair is free. The recall was expected to begin March 28, 2019. Owners can contact Proterra customer service at 1-864-438-0000, and should check their vehicle identification number (VIN) for open recalls.
