What 31 owners told NHTSA about the 2012 Honda Gl1800a

COLD ENGINE THROTTLE HESITATION. *TR

NHTSA ODI 10532620

THERE IS A PRONOUNCED HESITATION WHEN ACCELERATING FROM A STOP. MOST OFTEN WHEN FIRST STARTING THE ENGINE AT THE START OF A RIDE, OR AFTER SITTING WITH THE ENGINE OFF FOR A SHORT PERIOD OF TIME. THE HESITATION 'CLEARS UP' AFTER THE MOTORCYCLE HAS BEEN RIDDEN FOR A FEW MILES. ADDITIONALLY, THE MILI-SECONDS IMMEDIATELY AFTER THIS HESITATION ARE FOLLOWED BY A SHARP SURGE OF ACCELERATION - AS THE ENGINE 'PUSHES THROUGH' THE MOMENTARY LACK OF POWER, JERKING THE RIDER'S HEAD BACKWARD AND ROCKETING THE VEHICLE FORWARD. THIS IS PARTICULARLY DANGEROUS IN WET CONDITIONS, OR IN SLOW SPEED TURNS, SUCH AS THOSE OCCURRING WHEN ONE IS JUST PULLING OUT OF A DRIVEWAY, OR AWAY FROM SOME OTHER SUCH STOPPED CONDITION. *TR

MOTORCYCLE HAS A HESITATION WHEN APPLYING THROTTLE. THIS HAPPENS FROM A COLD START AS WELL AS DURING ENGINE WARM-UP AND OCCASIONALLY WHEN THE ENGINE IS AT NORMAL OPERATING TEMPERATURE. I HAVE NOTICED THE HESITATION AT FROM TEMPERATURES STARTING AT 40 F AND UP. AT FIRST I WAS THINKING IT MAY BE RELATED TO SUMMER BLEND GASOLINE'S OR LOWER OCTANE FUELS, TESTING DIFFERENT GRADES OF FUEL DID NOT SOLVE THE PROBLEM. THIS ENGINE HESITATION CAN RESULT IN AN ENGINE STALL WHICH CAN RESULT IN A CRASH IF THE MOTORCYCLE IS IN A LOW SPEED TURN. I HAVE BEEN TOLD THE MANUFACTURER IS AWARE OF THIS ISSUE. THIS PROBLEM EXISTS ON MOST 2012 AND 2013 HONDA GOLDWING MOTORCYCLES. I CONSIDER THIS HESITATION TO BE A SERIOUS DEFECT THAT AFFECTS THE SAFE OPERATION OF THE VEHICLE. THE PROBLEM IS WELL DOCUMENTED IN VARIOUS GOLDWING ONLINE SITES. *TR
