My Jaguar well all the sudden lose its power steering the ability to break and the ability to excelerate and the check oil light will come on. The dead battery light will come on. Nothing will happen prior at all these things happening it seems to be random. It’s happened to me twice in the same day in the only thing that seems to fix it seems to fix it is turning the car off and then back on again.
It sounds like you may be having a problem with the battery. There is also potential for issues with the alternator and charging system. You should have your battery, alternator, the wires involved with the charging system, and the connections of those wires checked and tested. You may also want to check your drive belt, as it is responsible for powering your alternator and supplying the vehicle with power. Good luck!
