Go to a service manager. Say you want to test drive an auto on the lot to make sure your car reacts the same way because your car is having issues and his tech's are blind siding you about it. Go for a drive WITH HIM in their car. Then take him for a ride WITH HIM in your car. If it's different have him give you a rental so they can see whats going on.

^ This is the logical way of going about things at a dealership.

If they refuse call SOA or go to a different dealership.
