I've had mine installed since September, and have literally had zero issues at all. 5,500 miles so far.I received mine in the mail today from MB and it works like a charm. I can't believe it's this simple, nor that Infiniti left it out. The comments we're hearing from Infiniti are laughable. It seems like they keep making stuff up to keep people from getting these.
I'll watch mine closely, but for now I no longer have to have the lovely Mrs. Jcbama85 tell me her Acura RDX has push button start and doesn't have to use a key like my QX30.
