Complete transmission failure 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 complete transmission failure gets reported
There are 5 reports of complete transmission failure 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 98,000 miles. It is the 7th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 44,000 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 $2,800–$8,000 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.
This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.
The same failure, every year of the Jaguar XF
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.
On the night of july 2nd. 2011, I stopped my 2009 jaguar xf in a parking lot. I was unable to turn the gear dial selector from s (sports) and noticed a warning which said gearbox fault. I turned off the engine and applied the parking brake. I was unable to restart the car as the transmission was still engaged. I was unable to use the internet on my cell phone but called a friend who googled the problem and told me to wait a while. I did this and was able to operate the gear selector dial and continue the 30 miles to my home. On parking at my home the same thing happened and I was unable to disengage the transmission selector dial. On exiting the car a warning sign indicated that the transmission was still engaged. I turned off the engine and waited and was again able to disengage the transmission. I believe this is a very serious safety issue and could have significant consequences if the transmission got stuck in reverse when in a busy parking lot or on a busy road. I have had other problems related to power drainage on this vehicle which rendered it unable to be opened or start. I no longer trust this car until the item is fixed…
Faulty transmission.....the vehicle will not engage in drive. Each time the vehicle comes to a stop the vehicle will shift into neutral. You will then have to turn the vehicle off and back on to go forward. But when the vehicle comes to stop the vehicle shifts out of gear again. A new trans is needed due to the 3rd and 4th gears no engaging. The vehicle is less than five years old, although it has over 140k miles. This seems to be a recurring theme with the xf model. This vehicle has always been serviced at a jaguar dealer and for the vehicle to require a new transmission is very saddening. How does a luxury brand fail so much with the powertrain. *tr
Tl* the contact owns a 2009 jaguar xf. The contact stated that while attempting to stop at an intersection, he engaged the brakes and the brake pedal sunk into the floorboard. The contact also mentioned that the transmission failed to shift into gear. In addition, the check engine warning light was continuously illuminated and the vehicle decelerated independently and without warning. The vehicle was taken to the dealer. The technician diagnosed that the catalytic converter was defective, the brake lines were corroded and the gear box needed to be replaced. The manufacturer was not made aware of the failure. The vehicle was repaired. The failure mileage was 44,000 and the current mileage was 71,000. *tr

How far this goes
This page is kept out of search results because 5 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 5 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 complete transmission failure happen on the 2009 Jaguar XF?
Across 5 owner reports that included an odometer reading, half were filed by 45,000 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 complete transmission failure on the 2009 Jaguar XF?
5 reports have been filed with NHTSA, about 0.6 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.
