2001 Jaguar XJ8

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2001 XJ8.

Transmission Automatic 5-spd

The 2001 Jaguar XJ8 is a luxury sedan equipped with a five‑speed automatic transmission that delivers 15 mpg city, 22 mpg highway and an overall 18 mpg according to EPA ratings. While the model registers a modest 14 total owner complaints, the majority stem from the electrical system and it carries a single recall, placing it well below the 1998 peak of 84 complaints and above the 2006 low of four. This middle‑of‑the‑range complaint level indicates that the 2001 year sits in a comparatively stable portion of the 1998‑2006 reliability curve, offering researchers a vehicle that is neither an outlier for problems nor a benchmark for flawless performance.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; spark plugs every 100,000 mi; coolant every 10,000 mi. The big-interval services (every 10,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2001 Jaguar XJ8 sits in a generation that saw a dramatic improvement after a troubled start: the 1998 model year recorded 84 complaints, which then plummeted to just 11 in 1999. The 2001 model year shows a slight increase to 14 complaints, but this remains far below the initial peak and is followed by a further drop to 4 complaints in 2006, indicating a maturing platform. Like the surrounding years, the 2001 XJ8 has one recall and 13 technical service bulletins, with no investigations. The top complaint areas for 2001 are electrical system, engine and engine cooling, and structure, though the data does not specify root causes. With zero crash complaints and only one fire complaint, the 2001 model year represents a relatively stable point in the generation’s arc, making it a sound choice for a used purchase, provided the recall and electrical items are checked.
