New $90,000 plus Jaguar XJL. The car has been in the shop Four times for over a total of 20 days. All kind of electrical problems, most prevalent is with Bluetooth disconnecting or instrument panel blanking out completely. Jaguar has no idea how to fix the issues and refuses to replace the computers. They have asked us to wait for a major software update that in July. This is our fifth Jaguar XJ and by far the worse electronics of any of the over 25 cars I have owned.
Would be a cool way for 1960s British rock star to go out.
