2018 Proterra Catalyst recalls
Battery Leak Can Cause Fire in Transit Buses
Some transit buses from these model years may allow liquid to leak into and collect inside the traction battery pack enclosure.
Loose Steering Gearbox Can Cause Loss of Steering Control
The steering gearbox bolts may loosen because the adhesive bonding the torque limiter plate to the bus body may be insufficient.
Steering Gear Bolts May Loosen, Risking Loss of Steering
Some Proterra Catalyst buses may lack the plexus adhesive between the torque plate and the chassis.
Roof Hatch Glass May Shatter, Dropping Fragments
Certain tempered glass roof hatches in these buses can shatter because of temperature changes and vibration while the vehicle is in service.
Air brake valve may fail, risking brake loss and crash
Certain 2017-2018 Proterra Catalyst buses may have swivel valves that do not adequately protect the air brake system from an air leak between the service reservoir and the air pressure source.
Clogged Tow Fitting Can Cause Brake Drag and Fire Risk
A mesh cap covering the airline on an optional tow fitting can become clogged with road debris in wet or harsh weather.
Front Tires Can Overload and Fail, Raising Crash Risk
Certain transit buses from 2015 through 2018 have a four-point height control system that can cause a load imbalance, putting too much weight on the front tires.
Moisture in Air Brakes Could Cause Brake Failure
Some transit buses are missing an air brake supply reservoir, which allows moisture to build up over time in the air brake system.
Incorrect tire pressure label may lead to tire failure
The certification label on certain buses may list an incorrect gross front axle weight rating and/or incorrect tire pressures.
