1999 Jaguar XK8

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1999 XK8.

Transmission Automatic 5-spd

The 1999 Jaguar XK8 pairs a five-speed automatic transmission with EPA fuel-economy ratings of 15 mpg city, 23 mpg highway, and 18 mpg combined. Within the model’s 1997–2005 production run, this model year generated 23 owner complaints—falling between the high of 32 recorded for 1998 and the low of 10 for 2001—with powertrain issues representing the top complaint category and one recall issued. That complaint volume situates the 1999 model in the middle of the XK8’s reliability spectrum, distanced from the turbulence of 1998 but not yet reaching the stability demonstrated by 2001.

Fitment & sizes

Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.

From the factory this vehicle uses a BCI 49 · 680 CCA battery, OE oil filter EAZ1354. Note the factory cabin air filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

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 1999 Jaguar XK8 sits at a clear inflection point in the first-generation XK8's federal complaint trajectory, with 23 complaints representing a notable drop from the 31–32 complaints recorded in the 1997 and 1998 launch years, yet still more than double the 11 complaints seen in 2000. Recalls similarly declined from two per year in 1997–1998 to one in 1999, a level that held steady through 2001, while TSBs fell sharply from 192 in 1997 to 36 in 1999, continuing downward to 15 by 2001 — suggesting Jaguar was actively resolving early production issues across the generation. The 1999 model's top complaint areas cluster around Power Train (5 complaints) and Engine & Engine Cooling (4), which together account for nearly half of the year's total complaints, followed by Vehicle Speed Control and Service Brakes at 2 each; the data does not specify root causes for these areas. Notably, the 1999 model recorded only 1 crash complaint and 0 fire complaints, and there were no federal investigations opened for any year in this generation. The overall arc — declining complaints, recalls, and TSBs from 1997 through 2001 — indicates that 1999 benefited from two years of post-launch corrections but still carried some residual early-generation risk before the platform reached its most stable years in 2000–2001. For a buyer considering a used 1999 XK8, the data suggests it is a reasonable but not optimal choice: meaningfully improved over the 1997–1998 models, though a budget allowing for a 2000 or 2001 model would likely yield a lower-risk ownership experience based on the federal record.
