Rust or structural corrosion on the 2003 Jaguar X-Type

Only 4 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 rust or structural corrosion gets reported

There are 4 reports of rust or structural corrosion on the 2003 Jaguar X-Type, 4 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 120,000 miles. It is the 9th most-reported problem on this model year.

The whole distribution

Percentiles of the 4 odometer readings owners gave.
10th25thMedian 75th90th
— — 70,000 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 $500–$6,000 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, every year of the Jaguar X-Type

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.

This seems to be a common problem in which no one seems to want to address. There is a known flaw in the manufacturing process of the jaguar x-type models from 2002-2005. The rocker panels which are constructed of steel, with no drainage holes and no corrosion protection. This is a safety hazard as the corrosion impacts the uni-body construction which impacts the side impact structure. Seems jaguar is aware of this matter yet refuses to admit a flaw and addresses complaints to this issue by offering cash assistance on a case by case basis and "codes" it as a customer courtesy. My vehicle is a 2003 x-type purchased new in 2002, rust was found showing through the sill plate from the inside out, 7 days over a 6 year warranty. In repairing this due to jaguar refusing to address the issue (yet offered me a courtesy of $3k towards repairs), the result was faulty mfg of '02 - '05 models in which the models where all defective. The rocker panel is built in steel, with no drainage holes allowing for salt/water to capture inside, thus corroding the unibody and a-frame of the car. I have receipts and online proof of this defect and ignoring…

40,000 miles NHTSA complaint 814760 filed 2010-09-16

Last year the car exhibited severe corrosion in the right and left "a" pillar area at the bottom where it blends with the rocker panel.working on the car recently, the corrosion has progressed to the point where the front jack lift point as outlined in the owners manual, is completely unsafe to lift from. The crystallization of the metals are passed the safe point. My major concern is at what point does the vehicle become unsafe to drive due to failure of side impact protection and passenger compartment safety. As I understand from other owners, jaguar designed this model so that the drains for the front windshield wiper and vent box drain into the a pillar. When the hole at the bottom gets plugged with mud or ice during the winter that water mixed with road salt creates the perfect environment for this resulting corrosion. This model car being driven in areas that use road salt for dicing as well as chlorides on gravel roads for dust control would all be deemed unsafe before the vehicles lifetime is used up. Totally unacceptable for a world class auto manufacturers. *tr

How far this goes

This page is kept out of search results because 4 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 4 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 rust or structural corrosion happen on the 2003 Jaguar X-Type?

Across 4 owner reports that included an odometer reading, half were filed by 70,000 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 rust or structural corrosion on the 2003 Jaguar X-Type?

4 reports have been filed with NHTSA, about 0.2 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.
