Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

An unsecured steering gear box could cause the driver to lose the ability to steer the vehicle, increasing the risk of crash or injury.

Proterra Inc.

(Proterra) is recalling certain 2018-2020 35 foot and 40 foot Catalyst buses.

Lack of plexus adhesive between the torque plate and the vehicle chassis may cause the bolts securing the steering gear box to loosen.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt. Owners’ complaints are counted on each vehicle’s page.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • How many have been returned or fixed isn’t in the notice.
