When wiring harness or short circuit gets reported

Owners of the 2008 Jeep Wrangler report wiring harness or short circuit at a median of 65,000 miles. A quarter of the reports come in before 40,000 miles and a quarter after 65,000 miles, from 9 reports that carried an odometer reading.

A part like this is normally expected to survive 88,000 miles. It is the 24th most-reported problem on this model year.

The mileage distribution

The reported range runs from 40,000 miles at the tenth percentile to 135,000 miles at the ninetieth, a spread of 93,950 miles across the middle 80% of reports.

When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.

0% of the dated reports were filed under 36,000 miles.

The whole distribution

Percentiles of the 9 odometer readings owners gave.
10th25thMedian 75th90th
39,050 miles 39,050 miles 66,500 miles 66,500 miles 133,000 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 fire is 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 $400–$3,500 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 11 model years of this car. It shows up earliest on the 2013, at a median of 45,000 miles, and latest on the 2000 at 145,000 miles.

By volume the 1998 carries the most reports, with 15; the 2008 has 9. A mode that appears across most years of a model is usually a design choice rather than a bad batch.

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.

What owners wrote

Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.

The sound in the dashboard for check engine light, all other lights door and seatbelt sounds do not work 90 percent of the time. 10 percent they will make a sound but then shut off. It is a mail jeep. I'm concerned thta something might have shorted out or will catch my vehicle on fire. When I told the dealership they told me it would cost a lot of money because they would have to take the dash out to find the problem. The reason so many miles is my postal route. This car should be reltively new for this to happened. *tr

On the 2008 jeep wrangler dashboard, the airbag warning light flashes on every other minute with a chime, an indication that there is something malfunctioning or interfering with the vehicle's airbags.this has been a recurring issue and concern for many 2008 jeep wrangler owners, including myself, and has been shown time and time again to be caused by a faulty clockspring within the vehicle's steering wheel. This faulty clockspring is the culprit for potential airbag failure in the 2008 jeep wrangler during an accident or premature deployment when simply driving around. Daimler chrysler has refused to address the safety concern of their faulty clockspring that can cause failure of the vehicle's airbags from properly deploying. Also on a different issue, on certain occasions I go to start my vehicle and I will hear a click and the vehicle will refuse to turnover, it is a random occurrence that is a huge inconvenience. Sometimes my jeep will start after 5 or 6 tries, other times it can take a half hour for it to finally start up. I have tried changing the battery to no avail and am hesitant to hire someone to go through all of the…

How far this goes

Complaints are voluntary, so 9 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 wiring harness or short circuit happen on the 2008 Jeep Wrangler?

Across 9 owner reports that included an odometer reading, half were filed by 65,000 miles. A quarter were filed before 40,000 miles and a quarter after 65,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.

How common is wiring harness or short circuit on the 2008 Jeep Wrangler?

9 reports have been filed with NHTSA, about 0.1 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.
