Other electrical problem on the 2009 Harley-Davidson Flhx
Only 6 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When other electrical problem gets reported
There are 6 reports of other electrical problem on the 2009 Harley-Davidson Flhx, 6 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 85,000 miles. It is the 1st most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 35,144 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
Putting it right typically runs $250–$2,000 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.
The same failure on other years
The same failure is reported on 3 model years of this car. It shows up earliest on the 2008, at a median of 15,000 miles, and latest on the 2009 at 35,000 miles.
By volume the 2009 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

Harley davidson flhx 2009 street glide we were on vacation leaving one town traveling to another and traveling on the interstate in the left hand lane moving with traffic, which was thick with cars, campers, trucks. All of a sudden I felt the motor cycle loose power, I glanced down and noticed the check engine light was on and I glanced in my right rear view mirror and there was a tractor trailer grill close. There was no shoulder on the left and I felt our lives threatened all I could do was motion with my hand my intentions of moving right to where there was safety away from traffic. The following codes I retrieved from my motor cycle: p1511 throttle actuator control power management mode, p2135 tps correlation error, p2176 tac close position not learned my motor cycle is bone stock and she has been serviced by harley all records and service are current. I drive my motor cycle daily weather permitting and I believe harley has been aware of this type failure since 2008 by the following links, http://www.scribd.com/doc/55139820/2008-later-touring-tt418-1 tt418: dtcs p2135 and p2101 theory and diagnostics november 3, 2009 the…
On acceleration from a stop the engine loses power and goes into an idle mode. This event also occurs when you're accelerating up to road speed and occurs without any warning, including situations where you're entering into an intersection and potentially in the path of other vehicles - in normal situations, you have plenty of time to have a safe distance to clear the intersection. When engine goes into idle you're basically without the ability to move off the road safely without potential for collision. The latest situation occurred on 7/3/2013 while I was passing a vehicle and accelerating to 70 MPH, with a passenger on the bike. The engine lost power and went into idle at 2000 RPM without the ability to decelerate or accelerate. I was trapped abreast of the vehicle I was passing - if oncoming traffic was in close proximity, I could have lost any ability to take actions to get back into my proper lane of traffic to avoid a conflict. *tr

How far this goes
This page is kept out of search results because 6 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 6 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 electrical problem happen on the 2009 Harley-Davidson Flhx?
Across 6 owner reports that included an odometer reading, half were filed by 35,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other electrical problem on the 2009 Harley-Davidson Flhx?
6 reports have been filed with NHTSA, about 1.4 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.
