One problem related to wiring has been reported for the 2003 Jaguar X-type. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2003 Jaguar X-type based on all problems reported for the 2003 X-type.
The 2003 and perhaps 2002 Jaguar x class have a "low outside temperature" screen that becomes visible when the car's thermometer reads 38 degrees outside; this normally occurs when driving subsequent to the car being garaged; to shut off this screen the driver must look to the left of the steering wheel and then down to find and press a reset button for 5 seconds; this presents an unsafe situation as the drivers eye contact is no longer on the road; moreover, the owner's manual claims the screen is suppose to shut off automatically after 4 seconds (page 4-12); the company and dealer I bought an x class from have been notified and refuse to respond to the issue. Jaguar told me the owners manual can be wrong and the dealer responded that it is a "black ice" warning. (I do not know what blace ice is. ).
