What Problems Does the 2020 Freightliner B2 Bus Have?

The 2020 Freightliner B2 Bus, being a robust chassis primarily utilized for school and commercial buses, generally boasts strong long-term reliability. However, like any heavy-duty vehicle, some common areas for attention can arise over time, often related to the extensive use and demanding operational environments.

One area that can sometimes require attention is the exhaust gas recirculation (EGR) system on diesel engines, particularly with high mileage and varied operating conditions.
