What's wrong?
The ride height system on 2015-2018 Proterra Catalyst transit buses controls how the bus sits on its suspension. On these buses, the four-point system uses air pressure at different corners of the vehicle to keep the body level and the ride stable as passengers, road crown, and turns change the load.
Proterra found that this setup can create a diagonal pressure difference in the suspension airbags. When one diagonal carries too much pressure, the load shifts unevenly through the bus and overloads one front tire. The root cause was not identified in the filing, but the problem is the load imbalance created by the four-point control layout, not normal tire wear.
A driver can notice a change in ride quality before the condition is found. The higher-pressure front corner hits bumps or holes harder, while the opposite corner feels softer over the same surface. That softer corner also has more body roll when turning away from it.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
An overloaded front tire can fail unexpectedly, increasing the risk of a crash. Treat uneven ride quality as a warning sign: one front corner hits bumps harder, while the opposite corner feels softer and rolls more in turns. Schedule the repair soon, and ask the operator or dealer before putting the bus back in service if those symptoms appear. Repair is free at any franchised Proterra dealer.
What should I do?
- Check your VIN to confirm your 2015-2018 Proterra Catalyst is included in this recall.
- Contact a franchised Proterra dealer to schedule the free ride-height system conversion that changes the four point system to a three point system and prevents front-tire overload.
- Bring the recall notice if Proterra mailed one, or reference recall number 19V062 when you call.
- Call Proterra customer service at 1-864-438-0000 if your operator needs help scheduling the repair.
- Avoid regular service use until the ride-height conversion is complete, because front-tire overload raises crash risk.
What happens at the repair
At the dealer, a Proterra technician converts the current four point ride height system into a three point system so the front tires are not overloaded. The recall repair is free, including parts and labor. Proterra has a general reimbursement plan on file for owners who paid out of pocket before recall work was available. Keep repair invoices and contact Proterra customer service to ask how to submit documentation.
