I may be wrong (often am!)
Do you have the car connected to the internet with the app? (Telematics). If not I cannot see how your car can be 'interfered' with.
Blutooth range is minimal and when you are moving I would say impossible to connect to by some miscreant.
When parked with ignition off the Blutooth will be off as well.
If you are really that concerned perhaps a bike would be better, because when Putin decides to cyber attack the U.K. we are all b*ggered! :'(
BTW. Do you have a smart TV?? Smart mobile?? They are far more at risk!
