Im not sure what was mean either in that post. He clearly wasnt catching on to the 15 posts above yours - it seems as though you were simply reiterating what others said. Only with a bolded font
To the OP. Im not even sure why you would leave a car at a stealership for 3-5 days for them to "Investigate". Thats what I would expect my work to be done in. Otherwise, pencil me in for an appointment, look and diagnose. Then Ill bring back for the work
And as the others have said - give up on email/calling them - go to the dealer in person.
I suspect this is going to be covered under your warranty. In fact, after seeing your tunnel vision in this thread, I am wondering if they already indicated this to you when you dropped the car off?
