NHTSA Complaint #10631150 — 2009 HARLEY-DAVIDSON FLHTC

THIS MOTORCYCLE, WITH NO WARNING WILL GO INTO "LIMP MODE". LIMP MODE IS WHEN THE ECM SHUTS THE ENGINE DOWN TO 1000 RPM AND WILL NOT LET IT EXCEED THIS RPM. TWICE THIS HAS HAPPENED WHILE IN HEAVY TRAFFIC AND ONLY BY THE GRACE OF GOD WAS I NOT RUN OVER FROM BEHIND. THE BIKE REGISTER THREE CHECK ENGINE LIGHT CODES, P1511, P2135 AND U1097. ALL CODES ARE ASSOCIATED WITH THE THROTTLE BY WIRE SYSTEM LOSING COMMUNICATION WITH THE CONTROL MODULE. TWICE THIS PROBLEM HAS BEEN ADDRESSED BY TWO DIFFERENT HD DEALERS AND BOTH DEALERS REPLACED CONNECTORS IN THE WIRING HARNESS. BOTH DEALERS HAVE STATED THAT IT IS A COMMON PROBLEM WITH 2009 MODELS AND THAT HD OFFERS O PIN UPGRADE KIT TO ADDRESS THIS PROBLEM, BUT THAT THE KIT SELDOM CURES THE PROBLEM. IT CERTAINLY DID NOT FIX MINE. IN MY HUMBLE OPINION HD NEEDS TO FIX THIS PROBLEM, IT IS A SERIOUS SAFETY ISSUE. THANK YOU. *TR
