Recall campaignsA 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.

22V114000

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.

What a recall is

Safety recall
A 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.
Safety investigation
NHTSA 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.
Manufacturer communication
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
