Fill the fronts up to 80 (so all are) or at least close and drive around a few miles.
See if it corrects.
Then set the tire pressure where you want it but keep it above 62 (at least that's where mine alerts).
They may have run it with lower than 65 psi and didn't clear the warning.
If that doesn't work, you'll have to retrain the TPMS system which is a pain.
Edit: I have Nitto Terra's and I run 75 up front empty and 68-70 rear empty.
If I get 65 or below in the back, I get a bad vibration but keeping it in the upper 60's eliminates that issue.

Yep. In order to reset, You need to inflate to the max pressure and then go for a short drive.
Just keep it above 62 psi unless you get the dealer to reprogram your settings.

If airing up to 80 psi all around doesn't work, there is a procedure in the manual to retrain.
That didn't work for me so I had to take mine to the dealer for them to retrain the sensors.

Understand that the retrain process an owner can do is only to teach TPMS where each tire is. TPMS is factory programmed for 65 front 80 rear. the retraining process is telling the computer which tire is where. Evidently the computer thinks one of your front tires is a rear tire, thats why it worked to air up the front.
The process the dealer can do, permanently changes the TPMS pressure settings to a different PSI. I had mine changed to 60psi on all 4 wheels for two reasons, now it is no longer necessary to retrain, and secondly, 80 in the rear is just too much when empty. I only want the light to come on when the tire is actually losing enough air that it is dangerous to drive.

It is my understanding that the threshold is set at 75% of the recommended 65psi front and 80psi rear pressures. I like to run my rears lower than my fronts when unloaded so I retrained the system and told it that the fronts were in the rear and the rears in the front. I aired down to 80% of recommended and after a few days the light came on so I went to 85% which puts me at 68psi for the front tires and 55psi for the rears and have not had the light come.
Per Michelin and my actual axle weights I can go even lower without safety issues.
