Proterra, Inc. recall for steering, reported to NHTSA on Feb 28, 2022, covering about 724 vehicles.
The problem
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.
