Other engine problem on the 2009 Jaguar XF
Only 5 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 engine problem gets reported
There are 7 reports of other engine problem on the 2009 Jaguar XF, 5 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 95,000 miles. It is the 4th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 37,000 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
Putting it right typically runs $300–$4,000 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 6 model years of this car. It shows up earliest on the 2015, at a median of 35,000 miles, and latest on the 2012 at 75,000 miles.
By volume the 2010 carries the most reports, with 10; the 2009 has 7. 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.

Tl* the contact owns a 2009 jaguar xf. The contact stated that while driving at low speeds the vehicle stalled with the illumination of the check engine warning light. The failure recurred sporadically. The vehicle was taken to the dealer several times for the failure where the dealer performed a diagnostic that was unable to locate a failure code. The dealer replaced the gear shift and the transmission control sensor. The failure was not corrected and the vehicle continued to stall. The manufacturer was contacted and they advised the contact to take to vehicle back to the dealer. The vehicle was not repaired. The failure mileage was 37,000 and the current mileage was 52,000. The VIN was not available.
Car stalls upon a "warm" start. May require 2 attempts for the car to stay running. Took it to the dealership 3 times and because the problem is intermittent, they were unable to replicate the problem. I was told by the dealership that jaguar north america is aware of the problem but there is no fix available at this time. *tr

How far this goes
This page is kept out of search results because 7 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 7 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 engine problem happen on the 2009 Jaguar XF?
Across 5 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 engine problem on the 2009 Jaguar XF?
7 reports have been filed with NHTSA, about 0.9 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.
