What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2001 Freightliner Conventional, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
FUEL LIFT PUMP LOSES PRESSURE OVER TIME CAUSING INTEGRATED CIRCUIT IN FUEL SYSTEM TO FAIL TO FUNCTION. DRIVER OF VEHICLE RECEIVES A WARNING LIGHT ON DASH,; THE ENGINE COMPUTER SOMETIMES DE-RATES THE ENGINE AND SOMETIMES SHUTS OFF THE ENGINE. THIS HAS HAPPENED TO ONE PARTICULAR BUS THAT SHUT OFF WHILE DRIVING DOWN THE ROAD ON A ROUTE. BUS TAKEN TO AUTHORIZED DEALERSHIP. IF THE DEALERSHIP CAN RESET THE CODE AND IT DOESN'T FAULT, THE VEHICLE IS RETURNED TO US CLAIMING NO PROBLEMS EXIST. THE BUS THEN DIES OUT AGAIN. LIFT PUMP MALFUNCTION ALSO DAMAGES INJECTOR PUMP. SHORTLY AFTER HAVING THE LIFT PUMP REPLACED, THE BUS IS DOWN AGAIN FOR AN INJECTOR PUMP. AT LEAST 3 OTHER SCHOOL DISTRICTS HAVE ALSO REPORTED SIMILAR TYPE INCIDENTS. WE HAVE A TOTAL OF 36 UNITS POWERED BY THE CUMMINS ISB225 ENGINE. WE ARE CONCERNED THAT THIS WILL CONTINUE OVER TIME AND THAT THE MANUFACTURER IS AWARE OF THE PROBLEM, BUT SELDOM DOES IT GET ADDRESSED WITH THE FIRST TRIP TO THE AUTHORIZED DEALER. BUSES THAT DON'T HAVE EXTENDED WARRANTY COVERAGE WILL BEGIN TO SEE MORE EXPENSIVE BILLS FOR REPAIR. *JB
