The Jaguar XJ is one of the safest cars around thanks to standard stability and traction control, a pop-up bonnet to protect pedestrians, eight airbags and the latest security features.

For post-2015 models a suite of extra safety kit is available including All-Surface Progress Control – helps the car to pull away smoothly on slippery surfaces – traffic sign recognition, park assist, reverse traffic detection and cruise control with queue assist.

In 2017, Jaguar unveiled new safety tech for the 2018 model year XJ, which includes forward traffic detection, lane keep assist, driver condition monitor and autonomous emergency braking, which now incorporates pedestrian detection.

The XJ hasn’t been tested by Euro NCAP because it's a niche model that won't sell in big numbers. However the XF, XE, F-Pace and E-Pace have all received a five-star rating, and you shouldn’t have any concerns about the flagship saloon, given the list of safety equipment which is shared with these models. Indeed, the XJ and XF are closely related under the skin, which will further boost confidence in the limo.

As for the mechanicals, all engines are well tried and tested and the eight-speed auto is durable too, according to respondent to past Driver Power surveys. As a manufacturer, Jaguar usually finishes higher than its German rivals for general owner satisfaction. The only real worry would be with some of the electrical systems, which can play up in Range Rovers and a large proportion of the technology is shared.

If you do need to visit a dealer, then according to Jaguar owners who participated in the survey, you can expect a better level of service at a Jaguar dealer than the equivalent Mercedes, BMW or Audi franchise.


All XJ's come with a three-year warranty which can be upgraded to an extended warranty to cover paint and bodywork. The extended warranty also includes roadside assistance. 


There are various service plans available and Jaguar now offers an online service so owners can remotely check their car's service history.
