What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2003 Triumph Speed Four, 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.

THE MANUFACTURER MADE THE CONTACT AWARE OF THE RECALL ASSOCIATED WITH NHTSA CAMPAIGN ID NUMBER 04V156000 (FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS), BUT STATED THAT THE VEHICLE WAS PREVIOUSLY REPAIRED UNDER THE RECALL.

TL*THE CONTACT OWNS A 2003 TRIUMPH SPEED FOUR. THE CONTACT STATED THAT THE FUEL CONNECTOR LINKING EACH OF THE FEED AND RETURN FUEL HOSES TO THE FUEL PUMP MOUNTING PLATE FREQUENTLY FRACTURES. AS A RESULT, GASOLINE DISPERSES FROM THE VEHICLE AND INCREASES THE RISK OF SERIOUS INJURY AND FIRE. HE TOOK THE VEHICLE TO THE DEALER ON TWO OCCASIONS AND HAD THE COMPONENTS REPLACED. SEVERAL MONTHS AFTER THE REPAIR, THE FAILURE RECURRED. IN ADDITION, THE GASKET ON THE GEAR SHIFTER IS LEAKING OIL. THE CONTACT IS IN THE PROCESS OF NOTIFYING THE MANUFACTURER.
