It's a brand new vehicle! I have been by the dealer 5 times to demonstrate the issue and taken it in twice for an appointment. Mazda has bombarded me with several kinds of surveys, but that does nothing! I called Corporate as instructed with a concern and let them know about it and they provided a case number and such. I have left a message with no return call. Also, Mazda has never followed up to see if it is getting resolved! The dealer reports that I need a whole new instrument cluster and they do not have access to such. As of two weeks ago, it was on back order (what-ever that means). Mazda should just send one from the factory is what I would think. I will keep you informed. It is not a bad problem, but a disturbing one for a BRAND NEW VEHICLE.

Update from Jun 22, 2017: I would have deleted the above, but the site won't allow it. I want to emphasize that the dealer has been great about getting me in and diagnosing, a loaner and such, but I never heard from corporate about allocating the part, follow up, or a simple return call. I am confident that the dealer will rectify this issue sometime. I also wish to say that the vehicle is awesome! They have done a super good job on this year's model and they make a nice product! I would buy another one. The problem with the issue is; driving at 60mph or so with the stereo on and noticing the tach in the red zone is very scary until getting used to it and it changes all the time. It is only the reading and not the motor racing!!
