Recalls, owner-reported complaints, investigations and safety data

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.
0
Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest Feb 28, 2022
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

STEERING:GEAR BOX (OTHER THAN RACK AND PINION)

Feb 28, 2022
724 units potentially affected
The defect: Proterra, Inc. (Proterra) is recalling certain 2017-2019 35 foot Catalyst E2, 2017-2019 40 foot E2, 2020-2021 35 foot RR, 2019-2020 40 foot RR, 2019-2022 40 foot ZX5, and 2020-2022 35 foot ZX5 buses. The plexus adhesive between the torque limiter plate and the bus body may be insufficient, causing the bolts that secure the steering gearbox to loosen.
The risk: A loose steering gearbox can cause a loss of steering control, increasing the risk of a crash.
The remedy: Dealers will install a mechanical fastener and new bolts on the steering gearbox, and install a new torque plate, as necessary, free of charge. Owner notification letters were mailed October 7, 2022. Owners may contact Proterra's customer service at 1-864-438-0000.

SERVICE BRAKES

Apr 9, 2019
39 units potentially affected
The defect: 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.
The risk: A build up of air pressure can cause the brakes to drag and possibly overheat, increasing the risk of fire.
The 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.
