Other fuel system problem on the 2015 Harley-Davidson Xg750
2 crashes 1 injury 3 of the 27 reports for this failure mention a crash, a fire, an injury or a death. Those are the owner's words on the complaint form, not a verified finding, and one report can mention more than one.
When other fuel system problem gets reported
Owners of the 2015 Harley-Davidson Xg750 report other fuel system problem at a median of 200 miles. A quarter of the reports come in before 100 miles and a quarter after 500 miles, from 27 reports that carried an odometer reading.
A part like this is normally expected to survive 90,000 miles. It is the 2nd most-reported problem on this model year.
The mileage distribution
The reported range runs from 100 miles at the tenth percentile to 1,000 miles at the ninetieth, a spread of 938 miles across the middle 80% of reports.
A window that narrow is the signature of a part that fails on its own schedule rather than on how the car is driven — which is usually a design or supplier problem rather than wear and tear.
100% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 72 miles | 116 miles | 240 miles | 520 miles | 1,010 miles |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Of these reports, 2 a crash and 1 an injury are mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.
Putting it right typically runs $300–$2,200 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
Almost at exactly 90 miles, when there is still 1.5 gal of gas in the cycle it will stall out like someone hit the kill switch so it throws you forward on the bike. Then it comes back on and practically throws you off backwards. It gets worse at the 100 mile mark as the "stall" will happen even in higher gears and at higher speeds. When I then put gas in it, the problem goes away for the next 90 miles. Not safe and inexperienced riders could be thrown off the bike. *tr
When launching from a complete stop the bike failed to accelerate.this happened on more then one occasion that day and then the low fuel light went on. I thought okay I am out of gas and that's what caused the motorcycle to lurch and then launch this is a very unsafe practice when I took it to the gas station to fill up what I thought was an empty tank I noticed the tank was half filled with gas. I filled it anyway and the problem went away, I believe the tank is either not pressurized correctly or the fuel valve is located at the wrong part of the tank. I have owned many of motorcycles and have never had this issue. I would like to see an investigation as to what the problem is I know I am not the only one with this issue based on the forums that I have read. *tr
At low fuel (approx .9 gallons left in tank), while accelerating from a stop, motorcycle will lose fuel pressure, unexpectedly throwing the rider forward. A second later, the fuel delivery resumes, throwing the rider backwards. Filling the tank with fuel fixes the problem until a low fuel condition is once again reached. This happened to me several times. Most recently when this occurred, I stopped to fill the tank. I put 2.6 gallons of gas in the 3.5 gallon capacity tank, and this solved the "lag and leap" problem. I have called h-d factory 3 times regarding this issue, they always refer me to my dealer, where the bike has already been in for this issue 3 times. I believe at low fuel condition, the remaining fuel in the tank is being forced away from the pickup during acceleration, and returning shortly thereafter, causing this very unsafe condition. *tr

How far this goes
Complaints are voluntary, so 27 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does other fuel system problem happen on the 2015 Harley-Davidson Xg750?
Across 27 owner reports that included an odometer reading, half were filed by 200 miles. A quarter were filed before 100 miles and a quarter after 500 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other fuel system problem on the 2015 Harley-Davidson Xg750?
27 reports have been filed with NHTSA, about 5.1 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
