We have a 2017 Tesla S and the car has been making strange sounds for last few months… we have taken the car to Pensacola Service center several times but keep getting run around … we are told it’s the driver unit. They won’t replace it until the car breaks down which is crazy! We can’t get a hold of anybody at Tesla and every computer refers us back to service center. We are ready to sell the car and leave Tesla… any suggestions?
