Never had the low tire pressure warning light come on for any of my vehicles but correct me if I'm wrong here, why would the RR tire show and issue and the LR not when there's clearly a pressure difference. And yes I'm aware of the pressure issues, the dealership was nice enough to rotate my tires during the last oil change but wasn't nice enough to adjust the pressure for me and I haven't had the time in the past couple days. I know the extreme cold has dropped the pressure but why is the tire with the lower pressure not showing an issue? Is this a sign of a TPMS sensor issue or failure?
Has your truck had its morning coffee yet? Deffinately something going on between the sensors and the computer, I would try the relearn procedure first to see if that solves the issue, but something is amiss causing the computer to flag the wrong tire as low. Have you done any Forscan changes? If so one of them may be causing an as of yet unconfirmed issue.
Have a 2016 Edge that showed 3 tires at 31 and one at 28. Normal psi is 35. Checked them all manually and they were all 34 or 35. That’s one reason why I ignore the tpms stuff and generally use my eyeballs....
Looks like all 4 tires should be lit up at those pressures. Try inflating at or above max pressure and then releasing air to the level you normally ride at.
Had the same issue on my 2019 (two weeks old), LR had more pressure than RR but was flagged by TPMS. I aired up to max then let it back out to my regular pressure and it resolved itself after a couple miles driving.
looks like when they rotated the tires, they didn't tell the truck!... so it THINKS the right rear tire (sensor) is low... where is THAT tire mounted?, probably on left rear.

So prior to the rotation, tires were 50 front 60 rear. After the rotation screen read 60 front and 50 rear. I called to let the adviser know that the tech didn't bother to adjust the tire pressure like they normally do. He advised that the simply moved the tires front to back and that they did not change sides. So it appears the sensors were changed during the rotation.

if that was so, the low tire and the light would both be on the wrong corner ie, the LR os low, but truck shows it to be the RR
When I rotate my tires I change the pressure (80 <--> 60). My truck figures out the correct locations on its own. I haven't found a need to perform a relearn. I guess my truck has a higher IQ?

In my experience, most dealers do not rotate this way unless you ask. they just front to back.
I had a dodge that was burning through the outside edge of the front right tire. I assumed they would do the above rotation, but they did not. Just front to back. morons. when I asked the service tech about it he said normal operating procedure for them was to just rotate front to back (unless otherwise specified by the owner).
Needless to say, I started going elsewhere for simple service.
From what I can normally see by the handprints in the brake dust, the wheels are normally rotated correctly. My assumption is that the "tech" that worked on the truck this time was either just lazy or inexperienced which would account for my issues. We have a high of 37 today at dinner time so I may venture out and mess with the tire pressure to see if that resolves things.
