The tire sensor receiver is occasionally dropping all four tires. More often when it's cold. Tends to drop them for 20-30 minutes. They usually them come back on.

The bluetooth is also intermittently dropping out. When it fails, it shows as Bluetooth Off in Setup. Unlike the tire sensors, it doesn't reset itself after a while. If I shut the vehicle down and then restart, it usually resets.

Anyone know what to do about these problems and if they are related?

I'm wondering if maybe is the same antenna or RF module that is used for both and that's what's in need of fixing,.

 

TPMS has its own receiver/antenna.

Are the problems occurring at the same time and always when cold?
