According to the tire pressure placard, my 2016 ACR rear tires are supposed to be set to 29 PSI and the front tires are supposed to be set to 35 PSI. I have had the car for almost 2 years and tires have always been set to 29 / 35 with no problems. Drove the car yesterday and the TPMS light came on and message said to inflate left REAR to 35 PSI (which is used for the front tires). I checked the left rear and it was at 29 which is what it should be at cold. I inflated it to 37 PSI and light went out. Lowered the pressure to 29 and the light is back on. Seems like the threshold in the module has somehow been changed. Anyone experience this? Is it an easy fix?
