I got 2016 Infiniti QX60 and all buttons in the dashboard stoped working the same with steering wheel. I can't change radio station or play music on am fm aux Bluetooth also can't change temperature or fan speed, make it quick nothing works. Just wonder if anyone had this problem before? This happens 2 time at 1 time dealership told me it was my USB flash stick that I had too much music on it but since that time I never plugged that drive back and after 2 months the same thing happened.
Please help me!!!

How long have you had the vehicle? Original owner or purchased used? Any warranty? If the flash drive has too many songs, the audio system won't choke and overwhelm your electrical system. Sounds like there's something wrong with the car's electrical system. Places like Sears Automotive, Pep Boys, Advance Auto Parts offer FREE electrical testing. Get your system checked.

I bought this car brand new from dealer.
I do have waranty but I dealer keep telling me all this funny things like too much music on USB drive or problems with my I-phone which is paired with the car by using Bluetooth and can't wait for new diagnostic results.

Your dealership is lying to you and needs to be called out for it. Is there another dealership you could take it to?
