Have an '11 GS with the tire pressure monitor showing 52 lbs on one of the tires. It is actually 30 lbs.
Any one have this problem in the past and know what the problem is?

Sounds to me like the sensor in that wheel may be failing,

My LF sensor did the same as it would warn of over pressure registering 45 PSI when the actual pressure was 30 PSI. This happened the summer of 2017 when the OEM sensors were 10 years old. I replaced all 4 of my sensors this spring when I put the car back on the road after winter storage. I have had no further TPMS warnings with the new sensors.
