My low tire pressure light won't go off on right front side 2011 SRX ant ideas on how to correct tried adding air stuck at 28 psi

Just stop by your local Cadillac dealer. It will take them less than a minute to reprogram your tire sensor. They will also check the programing for the rest of them. This happens often - no reason to worry at this time but do get it fixed soon just in case.

Its possible that your sensor is not actually sensing the correct tire. When they were rotated last, its possible the shop didn't rescan the sensors.....hence, the front thinks its on the back and the back thinks its on the front!

my car has aluminum alloy rims and this was happening to me also, took car in for service and tech had to take my right front tire off and sanded the excess corrosion from my rim, and then reprogramed the sensor.
