So I though the number above my mileage was miles per gallon because it was never my speed it was go all the way up to 99 the faster ID go. So its been stuck on 11 for some reason and I realized it says MPH, not mpg. So obviously it was never right in the first place, but now its stuck for some reason. Ive read it could be electrical, the odometer, the speed sensor, a fuse. I have a 2013 Hyundai Accent Hatchback SE.
Also I constantly hear tapping in my right wheel and was told i may need new calipers though they arent very old.
Also my serpentine belt squeals.
It is low profile which I don't like because it feels like my suspension is so tight on every bump.
Any suggestions on how I can fix myself would be greatly appreciated.

 

There are some things that we need to leave to the folks with the information, knowledge and equipment.
I believe this problem is one of them.
Throwing pats at a problem can get expensive and disappointing.
