Low tire pressure warnings!

[WashingtonDCeV]

Having this now for about 2 weeks now...

A. In the mornings, the low tire pressure comes on for the rear left tire - 22psi; all other tires are at 44 psi
B. After driving for about 0.5 miles, the tire pressure goes up to 26 psi; rear right tire now goes down to 20 psi!
C. I refill the tires (all 4) to 45 psi
D. Same thing happens next day!

Thoughts?

Do you have a tire pressure gauge? Check to see the actual PSI.

• If it is indeed dropping, take the car to the Service Center as you have a leak.
• If it is not dropping, take the car to the Service Center as you have a problem with the TPMS or software.

My tire sensor went off on the first week I had my car. I thought it was a fault. Good thing I checked with my tire gauge - the tire had a nail in it.

I am having a similar issue. TPMS says I have a flat in my right rear tire (I don't) as it fails to register ANY pressure. I changed out my TPMS with new ones twice and I still have the error. Going back to SC in a few days to get it sorted.

just got back from the service center- apparently it’s a known issue and is scheduled to be fixed in upcoming update

Nice! Did they provide a documentation in the invoice? If so, could you share? Thank you!

This is what was on the invoice - “Test drove vehicle and verified customers concern. Rear tires will occasionally swap positions on center display when driving. This concern is currently under investigation and will be addressed in a future firmware update. Verified all tire pressure monitoring sensors are reading correctly and et proper tire pressures. Vehicle ok to drive.”

Thank you!!! I can cancel my service appt now and just wait for the next OTA update. I had a feeling this was some sort of a software glitch. My sensor reading has gone full circle since I first noticed the issue. First RR, then LR, then RF then back to RR. Now it just goes back and forth between RR and LR.

UPDATE: So I friggin' hate it when this happens. I am all set to go in for my appt tomorrow for the TPMS and guess what? Automagically, all the sensors are now working?! WTF? I don't know if I should be happy or what. I guess I am cancelling my appt but I would be pissed if it comes back after tomorrow and have to wait another 2 weeks for an appt. Thinking good thought and crossing my fingers.

Ha ha...mine is still playing musical chairs with the warnings.

Update. The musical chair alerts are gone with installation with 2020.40.4! The funny thing is that I did have a slow leak in the rear right after all from a nail in the tire.

So did the error go away with the software or because you fixed the slow leak?

The update. The leak showed up right after
