I just had an issue with my 2015 Subaru Impreza in that the tire pressure light wont turn off (TPMS) after filling tires to the correct pressure. One of the tires had been low and the TPMS low air indicator was triggered on the dashboard.

Tire pressure light wont turn off
I inflated the tire to the correct air pressure as it was just a little low. After restarting the car a few times the TPMS low pressure light would still not turn off. Turns out after checking the manual I needed to drive at least 20 MPH for the TPMS to take another reading. After driving it over 20MPH the TPMS indicator light did take another reading and turn off.
Just wanted to mention that in case someone was having the same issue and wondering why it might not have cleared after verifying the tires. Another possibility is the air pressure is correct and the light stays on is your TPMS sensor is bad.
I did find that Amazon sells Subaru TPMS sensors HERE for a decent price. Not sure what the tire shops charge but I was surprised they were so cheap as I thought they cost more for a set of 4. Might be worth bringing my own new sensors to the tire shop if I need new ones.
Also if you are looking for some decent tires at a good price. I reviewed these Ohtsu tires that were rebranded Falkens you may want to check out.
