  • Common Problems with the Jaguar XJR and the Reasons behind Them

    17 January 2013

    Sold under the British Jaguar marque, the Jaguar XJ designation that was launched in 1968 was used for a series of luxury saloon cars. After going through a lot of style and performance enhancements through the years, the automaker came up with the supercharged Jaguar XJR in 1994 along with the production of the X300. Being the first supercharged road car that was manufactured by Jaguar, the XJR has instantly earned compliments for its hard-hitting performance. However, there are still some things car buyers should take into consideration when choosing the Jaguar XJR. Here are a few things to take note of before buying one.


    Transmission oil

    According to consumer reports, the Jaguar XJR's transmission oil is synthetic. Although Jaguar claims that the transmission oil does for the XJR does not need to be replaced, expert technicians highly recommend replacing the automatic transmission oil with a new Jaguar-approved fluid for every 60,000 miles.

    Engine

    Car owners have also noticed chain problems on the Jaguar XJR's V8 engine. The chain tensioners that are made of plastic have a tendency to fail prematurely and cause serious damage to the vehicle's V8 engine. This is a common problem that can be easily detected by the noticeable noise that the engine makes during a cold start or while idling. This noise is usually accompanied by a rough or uneven engine idle. Replacing the old components with new and improved ones fixes this problem with the XJR's engine.


    Fuel system and gasoline

    Consumers also reported problems with some replacement fuel filters for the Jaguar XJR. Because the connectors on these fuel filters were not made to the manufacturer's specification, the o-ring in the fuel line may not seat correctly and cause an inadequate seal at the connection. This inadequate seal may lead to a fuel leak and even fire if an ignition source is present.


    Electrical system

    Another problem that consumers have encountered with the Jaguar XJR is its loss of power during acceleration due to a problem in the electrical system. According to consumer complaints, the vehicle goes into "fail safe engine mode", loses power on a down grade, and will start again. Car owners have experienced these fuse, circuit breaker, and ignition issues with the 1998 to 2000 models of the Jaguar XJR.
