2015 Harley-Davidson XG750: fuel pump failure

Filed Aug 23, 2015 · Fuel system · 220 miles · MD

Fuel pump on the motorcycle is not in good working order when the fuel level emptys to a certain point in the tank not knowing when because their is also no gas odometer on the motorcycle the model begins to lag and leap at any time and as many times it wants to react as am twisting the throttle whether am switching gears or just in crusie it will do this cause me to lose control and may lose control at the wrong time like bad weather, up and go traffic, turning into streets, I have already took a fall on the motorcycle trying to making it inside the fuel island at a gas station and the timing when I was in my turn of a right going in the island it lag and leap at that time and took off on me causing me to fall and also the motorcycle I walked away unharmed just my motorcycle had road scratches going along the muffler and heat sheild and right side handle bar grip chipped..I took it to get service at the dealer for its first 1000 mile and while it was their they replace the fuel pump but it still does the same thing and only got worst. The next problem is the gear shift between 1st gear and 2nd gear most of the time is not completely in gear when switching between the two.

"with roughly .9 gallons of fuel in tank, when leaving a full stop, vehicle pauses hard on acceleration. Probable cause is fuel starvation caused by fuel flowing back in the tank, away from the front-located fuel pump, starving efi system of gasoline. As fuel moves forward after a brief pause in forward momentum, the pump has access to the fuel and the bike suddenly lurches forward. This happens multiple times as the fuel in tank travels forward and aft. Extremely unsafe condition at low speeds, especially at intersections when this is most likely to occur." indident took place on my way home "8/5/15" from picking up the new bike. I called the dealer, and they said they never heard of this issue. They said they would return my call, but they never did.

Very dangerous short stem mirrors, cant see behind you! Fuel pump/ pickup tube sucks air and bike stalls then lunges. Gear selection is difficult and hangs. Very weak front brakes. Timing shaft woodruff key breaks!

Upon reaching approximately 95-100 miles on a tank of gas I experience issues with fuel delivery and engine output. The motorcycle loses power and is non-responsive, then all of a sudden will shoot forward as it receives fuel again. This could cause loss of control or a multi-vehicle accident due to the unknown responsiveness. The problem gets progressively worse, and after about 10-15 miles of the symptoms the fuel light is then triggered. The issue does not happen when the gas tank is full, but only after using approximately 1.6 to 2.0 gallons of gas (or 95-100 miles of driving). I believe there is an issue with the fuel pump causing a loss of suction causing the bike to act erratically. I have spoke with many owners of the same bike and they have also had the same issue. Many have had their fuel pumps replaced but still experience the problem because of the faulty fuel pump design. I have set an appointment with my local dealer to have my bike repaired.

The bike surges when shifting gears, due to fuel pump not operating properly. It will start a lower speeds, then begin to happen at higher speeds. 2 fuel pumps have been put into the bike and the issue still happens.

Motorcycle lagged and leaped accelerating from a stop while low on fuel - this problem was said to be remedied after bringing it up with a dealer and they installed a new fuel pump... However the problem seems to have returned. Acceleration seems to stutter then return at full force in a split second, causing loss of traction and steering. Cannot stress enough how dangerous this is driving in an urban environment.

At about 81 miles on the trip odometer from a full tank there was hesitation with acceleration in 1st gear turning right from a stop up a slight incline. By 91 miles on the tank, any hard acceleration was followed by hesitation then surge. This happened in any gear not just in 1st. By 98 miles on the tank there was so much hesitation and surge that it felt too dangerous to ride. This is the second complaint regarding this issue (prior complaint the federal safety agency id number: 10721410) in spite of the fuel pump already being replaced by harley davidson less than a month ago for the exact same problem. Replacing a defective part with another defective part is not an adequate solution to a potentially very dangerous problem.

**this is my second complaint about this** the issue happened the first time at 86 miles on the motorcycle. It was fixed at about 500 miles. Now at 996 miles it's back. The issue happens when taking off from a stop. The motorcycle almost dies because it isn't getting fuel, then it gets fuel and lurches forward. There is still over a gallon of fuel in the tank and the low fuel light was not on at the time. I almost crashed and could have been hurt or killed by the traffic coming up behind me. The first time they replaced the fuel pump and I was told that it's a faulty design and the pickup comes off causing it to not pickup fuel properly. It appears the replacement came apart also. Is harley going to be pushed to redesign this before or after someone is hurt or killed?...updated 09/22/15 *bf updated 11/08/2017

Ok so first time I had an issue was in january when I noticed a major surge to the point of stalling out reguardless of fuel level in the tank. Took it to harley once and they could not replecate the issue. Second time within the same month same issue the fixed it by replacing the fuel pump stating it was faulty. Had no problems for months till recently in may I started noticing I was on the highway when my fuel was low and the light came on I pulled of at an exit to get gas and it started to surge again like it did before. Tank was almost empty so I filled her up. No problems the rest of the day. Next month of june I notice my light started coming on when I was leaving my work and when in first or second gear it surges really quick from power to no power to quick power all of a sudden. So I went and filled up the tank and yet again no problems. Seems to be happening around 100 miles per tank. And when at half tank taking right hand turns it looses power too. Very easily could through an inexperinced rider off if they dont know how to maintain throttle and clutch control. Also noticed she has issues with starting in the morning when cold if the bike sits out in the lot, have to give her gas to warm up. Liqued cooled and fuel injected motors should not have that issue especially with only 2000 miles on the motor bike is not safe at this time probably due to the amount of foreign parts on an american machine.

This is my second complaint, original complaint # 10721274. After filing the complaint, I took the vehicle to the dealer to be fixed 5/25/15 (miles in 106). I was notified by the dealer that they spoke to harley-tech support and the dealer was advised to replace the fuel pump (ref#248840 rep:john). I received notification the bike was ready to be picked up on 6/4/2015 ( all issues fixed- fuel pump [lag and leap condition] and a neutral switch for the indicator to work properly), I was not able to pick the bike up until today 6/7/2015. The vehicle out mileage was 126, then I drove for a short trip maybe 2 miles stopped / parked the vehicle for 2 hrs. I then started driving again, with in a couple of minutes I felt the bike stumble after starting from a red light (1st gear) and then again in 2nd gear. I continued to drive a little further and then from another stop the vehicle constantly surged/lurch and leap condition constantly through 1st and 2nd gear and finally stalled out ,also no low fuel indicator light on. The vehicle was towed back to the dealership with a mileage of 131 miles. So, within 5 miles and probably 15 minutes of driving the vehicle, it has failed again. I understand there is an investigation in place and that harley-davidson has knowledge of this issue, problem is their recommended fix is not working

With roughly .9 gallons of fuel in tank, when leaving a full stop, vehicle pauses hard on acceleration. Probable cause is fuel starvation caused by fuel flowing back in the tank, away from the front-located fuel pump, starving efi system of gasoline. As fuel moves forward after a brief pause in forward momentum, the pump has access to the fuel and the bike suddenly lurches forward. This happens multiple times as the fuel in tank travels forward and aft. Extremely unsafe condition at low speeds, especially at intersections when this is most likely to occur. I have to be excessively cautious to make sure there is over a half a tank of gas to keep this from occuring. The last time it occured, the low-fuel light had not even come on yet, (light is said to come on at .8 gallon left). This is extremly unsafe.

I experienced a lag and leap issue. I was riding my bike with about 83 miles on the tank of gas and out of nowhere it would pretend to stall and then take off. Would continually do this in the lower gears. Added a new tank of gas and it went away. Got to the same mileage and happened all over again. Harley replaced my fuel pump but it was very scary and I am worried it may happen again.
