What Problems Does the 2021 Freightliner B2 Bus Have?
While the 2021 Freightliner B2 Bus chassis is built for durability and reliability, common issues associated with heavy-duty vehicles and complex systems can arise.
One frequently reported area of concern across modern diesel engines, including those in the B2, relates to the exhaust aftertreatment system (EATS) – specifically the Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) systems. These components, critical for meeting emissions standards, can experience clogs or sensor failures if not properly maintained or if the bus experiences prolonged idling or short-haul routes that don't allow for complete regeneration cycles. This can lead to "derate" conditions, limiting engine power and requiring dealer intervention.
Electrical system issues, while often minor, can be a persistent nuisance. With extensive wiring for various safety features, lighting, and ancillary systems, loose connections, corroded terminals, or sensor malfunctions can lead to diagnostic trouble codes or intermittent functionality. These are not unique to Freightliner but are common across commercial vehicles.
Air brake system components, while robust, require diligent maintenance. Air leaks, compressor issues, or problems with the drying system can impact braking performance and lead to downtime. Regular inspections are crucial to prevent these. Similarly, suspension components, especially in high-mileage units or those operating on rough roads, will eventually require replacement due to wear.
Recalls are a normal part of the automotive industry, even for commercial vehicles. For the 2021 model year or similar chassis, recalls might address specific component defects from suppliers, such as steering linkages, brake line routing, software updates for engine control units, or issues related to specific body builder installations (e.g., emergency exit mechanisms, seat belt anchors). Operators should always check NHTSA's recall database for their specific VIN.
Long-term reliability is a strong suit for the B2, but over many years of service, operators should anticipate eventual wear and tear on major components like transmissions (requiring rebuilds), engine overhauls at very high mileage, and chassis rust, particularly in regions with harsh winters. Interior components also degrade with constant use. Proactive preventive maintenance is key to mitigating these concerns and extending the bus's operational life.
