What this means for you

Illness, injury, or structural failure has been reported. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The recall involves a structural vehicle defect (height control system) that causes tire overload, leading to unexpected tire failure and an increased risk of crash.

Plain-English summary

Proterra Inc. is recalling certain 2015-2018 Catalyst 40 and 35 transit buses. The affected vehicles are equipped with a four-point height control system that may cause a load imbalance, resulting in the front tires being overloaded.

An overloaded front tire may fail unexpectedly, which increases the risk of a crash. Proterra will notify owners, and dealers will convert the current four-point ride height system into a three-point system to prevent the front tires from being overloaded. This repair will be performed free of charge.

The recall began on March 26, 2019. Owners may contact Proterra customer service at 1-864-438-0000. 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.safercar.gov.
