2006 Jaguar XJ8

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2006 XJ8.

Transmission Automatic 6-spd

The 2006 Jaguar XJ8, a full-size luxury sedan with an aluminum body and independent suspension, pairs a 6-speed automatic transmission with fuel economy ratings of 16 city, 25 highway, and 19 combined mpg. With only four owner complaints on record—all concentrated in the Power Train area—and zero recalls, this model year marks the lowest complaint count in the XJ8’s 1998–2006 history, positioning it as the most trouble-free iteration of that generation for researchers examining long-term reliability trends.

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 at 150,000 mi. The big-interval services (at 150,000 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 2006 Jaguar XJ8 sits at the low point of a steep downward complaint trend within this generation’s federal record, registering only 4 complaints compared to 14 in 2001, 11 in 1999, and a peak of 84 in 1998. Unlike the 1998, 1999, and 2001 model years, which each carried 1 recall, the 2006 model shows zero recalls and zero investigations, with TSBs holding steady at 13 across all recorded years. The four complaints are distributed evenly across the categories of Power Train; Fuel System, Gasoline; Suspension; and Electrical System, with one fire-related complaint recorded, though the data does not specify a root cause. Crash-related complaints are absent for this year. This positions 2006 as the most federally quiet year in the provided arc, implying a more stable production period relative to earlier model years in the record. Consequently, based strictly on this federal track record, the 2006 model represents the strongest year to buy within the dataset.
