Example complaints
Electrical system: “Problems with 2003 Jaguar XK8 stalling. While driving the vehicle stalled intermittently. The consumer came to the conclusion that when his knee accidentally hit the keys in the ignition the vehicle would stall.”
NHTSA complaint #10024466, filed 2003-06Transmission and drivetrain: “After slowing the car, the transmission downshifted in a harsh, sudden manner, and then the car accelerates abruptly and surges forward with a clunking sound. An amber warning was displayed on the dash saying gearbox fault . If someone was in front of the car when it surged forward they might have been struck.”
NHTSA complaint #10549709, filed 2013-10, 60,100 milesElectronic stability control: “The combination of the tires and the new dynamic stability control system produced a situation where if there's low temperature/snow on the ground, the vehicle would only move at a crawl.”
NHTSA complaint #10065090, filed 2004-03Wheels: “I own a 2003 XK8 Jaguar convertible with standard factory wheels.. My tire went flat while driving on the freeway. The flat could not be repaired because the wheel had cracked on the inside of the wheel, causing the air to leak from the tire. The wheel was not involved in any major collision but did show curb bump damage on the outside and a small area of flattening on the inside. No direct damage to the area of the crack. Obviously, a wheel should not track from minor road hazards. I became most suspicious when I tried to replace the wheel and I was told that the wheel had been discontinued. …”
