STEERING:GEAR BOX (OTHER THAN RACK AND PINION)
- 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.
- What it can cause
- A loose steering gearbox can cause a loss of steering control, increasing the risk of a crash.
- What the dealer does
- 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.
- NHTSA's note
- Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner.
Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup .
| Vehicle | Model years | Safety record |
|---|---|---|
| ProterraCatalyst | 2015 to 2022 | Not published here |
| ProterraZX5 | 2015, 2016, 2019, 2020, 2021 and 2022 | Not published here |
How this campaign compares
At 724 vehicles this is a bigger campaign than 55% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published. The middle campaign on file covers 472. It covers model years 2015 to 2022, so the oldest vehicles on it were 7 model years old when the defect was reported to NHTSA.
Proterra vehicles have been recalled over the steering 2 times before this, most recently in October 2020 as 20V664000. That is not evidence the earlier repair failed.
The vehicles on this campaign carry 10 other recalls published here, the newest being: 24V655000 (electrical system), 23V697000 (electrical system), 23V078000 (visibility), 22V887000 (electrical system).
Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
Filed by Proterra, Inc. with NHTSA on February 28, 2022 as campaign 22V114000. Every word of the defect, consequence and remedy above is NHTSA's published record of that filing, not a summary of it.
