2021 IC BUS CESB Complaints and Recall Information
The 2021 IC BUS CESB has 2 complaints and 4 recalls filed with NHTSA. Owners most frequently report engine exhaust downpipes melting due to excessive heat or fuel, causing cracks and exhaust leaks near the body firewall. This condition creates a potential risk of exhaust or flame escaping from the pipe.
There are four recalls affecting various systems including braking, structural integrity, and engine control. These recalls address defects that could impact vehicle safety and performance.
- Exhaust downpipe melting. Repeated melting of engine exhaust downpipes from heat or fuel results in cracking and exhaust leaks near the firewall, with risk of flame escaping.
The recall issues affect hydraulic brakes, body structure, and engine control modules among others. Repairs involve component replacements or reprogramming to mitigate safety risks.
- Brake pressure switch leak (25V503000). Affecting 16,553 buses, the brake pressure switch assembly may leak fluid causing electrical short circuits and fire risk. Owners are advised to park outside until repair installs a silicone jumper harness.
- Body underfloor reinforcement (25V580000). Affects 193 buses with missing underfloor reinforcement compromising structural integrity and compliance with FMVSS 210 and 222. Dealers will inspect and install reinforcement channels free of charge.
- Brake pressure switch leak (23V398000). Covers 15,398 buses with brake pressure switch fluid leaks causing electrical shorts and fire risk. Repairs include replacing the switch assembly, wire harness, or fuse. Owners should park outside until repairs are completed.
- Engine control module fault (21V837000). Affects 7,322 buses where ECM fault codes cause unexpected engine shutdown increasing crash risk. Dealers will reprogram the ECM at no charge.
Owners dealing with repeated repairs, safety defects, or unresolved recall issues with the 2021 IC BUS CESB may have rights under their state’s lemon law and should consider consulting legal counsel for assistance.

SERVICE BRAKES, HYDRAULIC:FLUID
International Motors, LLC (International) is recalling certain 2016-2024 IC Bus CESB school buses. The brake pressure switch assembly may leak brake fluid into the brake pressure switch's electrical components and cause an electrical short-circuit.
Risk: An electrical short in the brake pressure switch can overheat the circuit and increase the risk of a fire while driving or parked.

STRUCTURE:BODY
International Motors, LLC (International) is recalling certain 2020-2026 IC Bus CESB and 2021 RESB school buses. The underfloor reinforcement may not have been installed, compromising the structural integrity of the buses. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 210, "Seat Belt Assembly Anchorages" and 222, "School Bus Passenger Seating and Crash Protection."
Risk: Reduced structural integrity may increase the risk of injury in a crash.

SERVICE BRAKES, HYDRAULIC:FLUID
Navistar, Inc. (Navistar) is recalling certain 2016 and 2018-2024 IC Bus CE school buses. The brake pressure switch assembly may leak brake fluid into the brake pressure switch's electrical components and cause an electrical short-circuit.
Risk: An electrical short in the brake pressure switch can overheat the circuit and increase the risk of a fire while driving or parked.

ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM)
Navistar, Inc. (Navistar) is recalling certain 2020-2023 IC CE school buses. The engine control module (ECM) may set a fault code that results in an unexpected engine shut down.
Risk: Unexpected engine shut down can increase the risk of a crash. Additionally, a disabled school bus may require an evacuation procedure in an uncontrolled traffic situation, increasing the risk of injury to passengers.
Complaints
2021 IC BUS CESB
ID: 2080465FUEL/PROPULSION SYSTEM
School buses. We have a fleet of these and the condition is happening repeatedly and to almost every bus with this PSI brand 8.8L gasoline engine. The engine exhaust downpipes melt from excessive heat and/or fuel. The pipes then crack and produce an exhaust leak near the body firewall. Potential for exhaust and flame to escape from the pipe.
