Dear Proterra Vehicle Owner,
This notice applies to certain Proterra 35’ Catalyst, 35’ ZX5 and 40’ ZX5 Transit Buses, equipped with windshield wiper motors supplied by Doga USA Corp. and produced between June 1, 2020 and January 1, 2022.
What is the reason for this notice?

This may cause a noncompliance with Federal Motor Vehicle Safety Standard (“FMVSS”) 104 – Windshield Wiping and Washing Systems, and may cause reduced visibility or loss of visibility in certain conditions, increasing the risk of a crash. Wiper motors within the recall population will be replaced with new wiper motors at no cost to the vehicle owner.
Why is your equipment being recalled?
Vehicles equipped with the affected windshield wiper motors are being recalled because a wiper motor that operates intermittently or stops operating may cause reduced visibility or loss of visibility in certain conditions, increasing the risk of a crash. Proterra will provide a replacement of the affected wiper motor at no cost to you. We apologize for the inconvenience. We are committed to your safety, the safety of your customers, and your continued satisfaction with our products.
