I was wondering if anyone could help me. I just upgraded to 20" Helo rims on my 2015 200 S AWD. At first it was fine driving home but after about 20 minutes my tire pressure waring light came on and was not reading any of the tires pressure. I have been back twice now to have reset and its fine at first but always goes back to no reading. They did put new sensors on and said they are not sure why it keeps doing it. Note: I purchased from a tire place not a dealer. Anyone else have this issue or have any input?
