I have a 2008 nissan maxima se I have been having 3 problems for awhile now. One is my gas gauge does not work right, it shows less then what I really have in my tank and I know for a fact my car is better on gas. Second my low tire pressure light is always on, even after I got new tires put on not too long ago it still is always on. Last my display screen flashes on and off. I would like to know what could be causing these problems and what needs to be done for it to be fixed? Thanks!
As far as the fuel gauge, if you are correct and it isn't reading properly, most likely the float is bad. One of the tires must have a bad sensor. Have the computer scanned to identify where the problem is coming from. I would recommend you check for bad body grounds when it comes to the display screen.
