Two issues surfaced recently. One, the fuel gauge and tire pressure system.

What is your question?

A couple of days ago the fuel gauge stopped working and by that I mean it did not go down as fuel was used (staying on 1/4 tank) and the "Range" limit stayed stuck at 51 miles. I stopped and got fuel and it recovered to full and a 329 miles but it seems to stay there and then all of a sudden drop as if a gallon just disappeared. And then yesterday the tire pressure system started flashing that it was not working. Anyone hear if this is a broad issue or have any idea if they are related?
