1999 Jaguar Jx8 problems
The Jaguar XJ (X308) is a full-size luxury saloon car manufactured and marketed by Jaguar Cars for years 1997–2003 across two generations and featuring the Jaguar AJ-V8 engine and Jaguar independent rear suspension. It was the third and final evolution of the Jaguar XJ40 platform that had been in production since 1986. It was preceded by the Jaguar XJ (X300).
Exterior
The X308 kept much of the same exterior styling as its predecessor, the Jaguar XJ (X300), carrying its rounded four-headlamp bonnet, low roofline, sloping tail, and wrap-around rear light clusters. From the front, the two generations can be differentiated by the shape of the indicator lenses (rectangular on the X300, oval on the X308), and also by the shape of the fog lamps and lower valance air intake, both of which are more rounded on the X308.
The front and rear bumpers were both changed along with the taillights which had red/clear lenses rather than red/grey lenses. The grille surround and badging was slightly changed. The headlight fixtures also included forward parking lights housed with the brights, new to X308.

Common 1999 Jaguar Jx8 problems
The Jaguar XJ8, produced in 1999, is known for several common problems that have been reported by owners. These issues range from mechanical faults to cosmetic concerns.
One of the most frequently reported problems is related to the fuel system. This issue manifests as a car that sounds like it is running out of fuel. The recommended solution is to have the fuel-injectors and throttle body cleaned.
The 1999 Jaguar XJ8 also had problems with the throttle not opening properly, a problem that was more prevalent in the 1998 models. Additionally, some 1999 cars had transmission glitches that caused them to lock up. These issues highlight the importance of checking the throttle and transmission when considering the purchase of a 1999 XJ8.
Another common problem is related to the cooling system. The plastic thermostat housing is known to crack and leak over time. This is an inevitable issue due to the use of plastic in the housing. The tensioners in the V8 engines are also made from plastic and can break due to stress, causing metal on metal friction between the timing chain and the tensioner. These issues can lead to excessive wear in the valve body, causing random pressure spikes, and can break the snap ring on the A-Clutch drum.
Cosmetic issues are also common in the 1999 Jaguar XJ8. For example, the center cup holder may not stay latched, and the tires may be of mixed breeds, requiring replacement. The third brake light may also be faulty and require repair or replacement.
In conclusion, while the Jaguar XJ8 is a luxury vehicle known for its performance and style, it is not without its common problems. Potential buyers should be aware of these issues and consider them when making a purchasing decision. Regular maintenance and checks can help to mitigate these problems and ensure the longevity of the vehicle.
What problems did the 1998 Jaguar XJ have?
1998 XJs had problems with throttles not opening properly, and some 1999 cars had transmission glitches that caused them to lock up. You should also check - or get someone else to check - that the throttle is not fouling the underbonnet liner and that the power steering pipe is not chafing the alternator terminals.
What is the problem with the 4.0 Jaguar engine?
The Jaguar V-8 4.0 & 4.2 Liter engines are very prone to coolant leaks, due to the use of many plastic components. The most troublesome parts are the thermostat housing and the water pump.. We replace the 4.0 Ltr plastic housing with an aluminum version that solves the problem.

Are 90s Jaguars reliable?
Jaguar XJ Sedans
For many Jaguar fans, the models released in 1995-1997 are the most reliable vehicles the brand has ever produced and, by extension, some of the most reliable cars of the 90s. Sadly, Jaguar canceled the XJ series due to production capacity issues.

THE THROTTLE CONTROL HAS BEEN REPLACED 4 TIMES. THE ENGINE LIGHTS GO ON IN THE DASH AND THE CAR GOES INTO LIMP MODE EVEN ON THE HIGHWAY. THIS IS VERY DANGEROUS. THE LAST SERVICE FOR THIS COMPLAINT WAS THE FIRST PART ON JULY. THIS IS THE 14TH OF JULY AND THE SAME PROBLEM HAPPENED ON THE HIGHWAY FORCING MY HUSBAND TO EDGE INTO THE SHOULDER OF THE ROAD AND STOP THE CAR, TURN THE ENGINE OFF AND WAIT. THE LAST REPAIR WAS SUPPOSED TO BE THE LAST AND WE REFUSED TO PAY YET AGAIN FOR THE SAME REPAIR. NOW WE ARE AGAIN WAITING FOR THE NEXT EXCUSE FOR NOT REPAIRING THE VEHICLE.

- Date Of Incident: 2024-11-24
- VIN: SAJHX1046XC
- Components: FUEL SYSTEM, OTHER,ELECTRICAL SYSTEM
- Summary: DEALER SAID THEY HAD SEEN OTHER PROBLEMS WITH THE SPARK PLUG FAILURE. THEY REPLACED BOTH THE PLUGS AND FUEL GASKET AND FUEL SENDER AT NO CHARGE. I WAS LUCKY, THE CAR WAS PARKED IN OUR GARAGE WHEN IT FAILED. I HAD NO POWER AT ALL. IF I HAD BEEN ON THE ROAD AT NIGHT ALONE AND THE CAR FAILED, I COULD HAVE BEEN IN SERIOUS DANGER. WHEN I TRIED TO START THE CAR, IT WAS CLEAR IT WAS NOT THE BATTERY BECAUSE I HAD THE RADIO AND LIGHTS JUST NO TURN OVER OF THE ENGINE AT ALL. THE FUEL GAUGE WAS STICKING. WHEN I WOULD FILL THE TANK, OCCASIONALLY, THE DASH INDICATOR WOULD NOT REGISTER THE FILLING. THE NEEDLE EVENTUALLY, HOWEVER, WOULD COME UP TO INDICATE A FULL TANK. SOMETIMES, TURNING OFF THE ENGINE AND TURNING IT BACK ON WOULD CORRECT THE FAILURE. *AK
