The Jaguar S was first released in 1963 as a luxurious yet compact and affordable alternative to the Mark 2 and Mark X models. Its production ended five years later in 1968, but the model was revived more than 30 years later in 1999. Its second coming enjoyed popularity with the fusion of classic appeal and modern specifications enticing different generations of consumers. However, there were some issues that came with second generation of the Jaguar S-Type. Here's a list of some of them:
One issue on the fuel system of the Jaguar S was its fuel filter and the filter's connector. In June 2006, Jaguar notified their customers and recalled almost 59,000 affected units. Most vehicles were diagnosed and it was found that the quick connectors and the tube interface of the fuel filter were designed incorrectly. This problem could cause fuel spillage and start a fire if there's a presence of any ignition source. The fuel filter of these vehicles were replaced free of charge.
Another problem with the fuel system of the vehicle was the fuel tank and its parts. The tank's jet pump module, fuel delivery module, and cluster valve seals were not retained properly. These parts could cause the malfunction indicator lamp to light-up or fuel odor to be noticeable in the passenger area. There were more than 13,000 units potentially affected with this problem. Jaguar recalled the vehicles in October 2006 for inspection and repair. A new gas tank was installed for vehicles that that still malfunctioned beyond repaired.
The Jaguar S also had a passenger-safety issue particularly on the TRW seat belts of the vehicle. After the diagnosis of the National Highway Traffic Safety Administration, it has been ruled that the buckle base of the seat belt assemblies were not heat treated properly. The seat belts also failed the load bearing requirement of the Federal Motor Vehicle Safety Standard.
Around 5,400 Jaguar S units were potentially affected by this problem. Jaguar recalled the vehicles on August 2000, and the dealers were tasked to inspect and change the seat belt buckles if necessary.
