NHTSA Complaint #11083185 — 2012 YAMAHA XT1200Z

I HAVE HAD NUMEROUS ELECTRICAL FAULTS RESULTING IN LOSS OF POWER WHILE RIDING AND IDLE SPEED SURGES, RESULTING IN THE VEHICLE ACCELERATING WITHOUT WARNING. THE SURGE OF ACCELERATION CAUSED ME TO REAR END A VEHICLE UNDER NORMAL BRAKING, WHEN DOWN SHIFTING CAUSED THE BIKE TO LURCH FORWARD WITH AN IDLE SPEED ABOVE 4000 RPM, IMPACTING THE VEHICLE IN FRONT OF ME. LUCKILY, I WAS ABLE TO SLOW THE VEHICLE BEFORE IMPACT SO THERE WAS ONLY SUPERFICIAL SCRATCHES FOUND. THE SUDDEN ACCELERATION CAUSED A LOSS OF CONTROL WHICH RESULTED IN THE IMPACT. I HAVE ALSO RECENTLY HAD MORE ISSUES WITH THE CYCLE DISPLAYING AN ERROR CODE AND NOT STARTING, LEAVING ME STRANDED ON A RIDE. THE PROBLEM HAS BEEN INTERMITTENT FOR OVER THE PAST TWO YEARS AND HAS HAD ME TO REPLACING SENSORS, COILS AND ADDITIONAL MAINTENANCE COSTS ATTEMPTING TO FIX THE ISSUE. RESEARCH WITH OTHER OWNERS OF THE MODEL HAS LED ME TO THE CONCLUSION THAT A FAULTY WIRING HARNESS IS TO BLAME FOR THESE EVER PRESENT ELECTRICAL ISSUES. YAMAHA NA APPEARS TO BE AWARE OF THE ISSUE, AS OTHERS HAVE HAD THEIR MAIN WIRING HARNESSES REPLACED AND REPORT NO FURTHER ISSUES.
