OP, what number at BMW NA did you call? I found the Customer Relations department at "BMW NA" to be totally useless. The contact number I used was the one in the Owner's Manual. All they told me was they would call the Dealership to try and resolve the problem; BFD.
In reality the Customer Relations department of BMW NA is a just call center located in Columbus, Ohio. When I asked their "complaint resolution specialist" for a phone number to someone in BMW NA Headquarters in New Jersey they told me they are not affiliated with BMW NA in New Jersey and could not get a phone number.
When I went back to the dealer and asked their Customer Relations Specialist for a contact at BMW NA HQ in New Jersey, I basically got told "pound sand".
So if you have a real point of contact at the real BMW NA in New Jersey, I'd appreciate it if you could share it with me.
