The plastic coolant reservoir is prone to leak. The reservoir can mysteriously lose coolant or coolant may pool under the engine compartment. If this occurs, the coolant reservoir should be inspected for cracks. If leaks are neglected, the reservoir may fail and cause the engine to overheat.

2003 Jaguar S-Type Problems
Ignition coil failure may cause the engine to run poorly. The fault can be intermittent and may or may not illuminate the Check Engine Light.
Premature automatic transmission failure is common. Diagnoses of the fault will be necessary to determine if repair or replacement is the proper repair.
A plastic component in the HID head light may fail and cause the head light to point toward the ground. The adjuster—which is very expensive—needs to be replaced to fix the problem.

My module is out on the car and it's not reading thew key which is causing it not to turn over. The light on the dash board doesn't light up so therefore I think the module is out. How much will it cost to repair it. Please give me a call at 682 552 5544 if you need additional information....Thanks
I experienced involuntry acceleration in my 2003 jag s/type. When I went to apply the brake at a stop sign, the car accelerated at a high speed on to traffic. With both feet on the brake the car continued out of control. You could hear the car reving. in order to avoid hitting others I steered the car toward a high curb hoping this would stop the car. The car incurred damage to the rt. front wheel/tire and the undercarriage of the car. This did stop the rpm but did not stop the damage to my nerves. I will never drive a Jag. again. This is a safety issue that needs to be addressed by Jaguar. I am not the only one that has experienced this terrifying incident.I contacted the NHTS administration and they told me that they have had similar complaints. Be Careful...don't buy a jag.
My 4.2 is a Dream car. I have had a few little things go wrong. ( Throttle Body replaced. Water pump Replacement. Driver side rear Axle went out), then the things you knew would go wrong, things like, the Brakes I Did not change the Plugs for 109,000,and it never missed a beat. Great Fuel car. The Brakes last longer than any car I have owned. You also have to take care of it. Run Good Fuel Mid- Grade, 76, Standard, Snoco when I was back east. You still have the best looking Jaguar on the street. But I also have 113,679 on it also,all mine. There is some front end work I hear now, up front maybe bushings I will replace all 8 of them front and rear, the noise is from the passenger front side. We brought it in Detriot. Troy Michgan and had it shipped to California. Its pretty good to us. I really like the new Supercharged Jaguar. I'm thing about buying another one. So you people that are not happy. You should buy an new one and you will be happy with your investment.
need to know what is piece that your br=eak light fit into need
to order another one
Like other reviewers, my car has been in the shop so many times for heating and a/c related events. The biggest problem I see is the shop doesn't check out all the issues at once. They know that one issue will cause a problem for another, but they only fix the immediate issue......and hope you come back the very next month or sooner to fix the other issue(s). It's called labor $ per hour, they will gladly take your car apart again for 8-10 hours at $125/hr. Make sure to ask them to look at ALL items affected by one part leaking or going bad... if you don't ask, they will not look.
