May 30, 2019 NHTSA CAMPAIGN NUMBER: 19V402000
Swivel Valve may Allow Loss of Pressure/FMVSS 121
If the swivel valves are unable to protect the air brake system against loss of air pressure, this may lead to service brake failure and the possibility for the uncontrolled application of the safety brake. Either condition increases the risk of crash.
NHTSA Campaign Number: 19V402
Manufacturer Proterra Inc.
Components SERVICE BRAKES, AIR
Potential Number of Units Affected 77
Summary
Proterra, Inc. (Proterra) is recalling certain 2017-2018 Catalyst buses. The vehicles are equipped with swivel valves that may insufficiently protect the air brake system from an air leak between the service reservoir and the source of air pressure. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, “Air Brake Systems.”
Remedy
Proterra will notify owners, and will replace the swivel valve with a check valve that is sufficient to protect the air brake system, free of charge. The recall began July 26, 2019. Owners may contact Proterra customer service at 1-864-438-0000.
Notes
