I've had that warning off and on for a couple years, mostly "on" nowadays. I don't have the Bumper Pinch problem, and I changed antennas in the wheel wells.
From what I learned a few years ago, of TWO sensors lose contact, it triggers the System Fault. That could be due to two TPMS sensors or a whole system explosion. Dunno, I may be wrong.
I DID update/reflash the TPMS module awhile ago and all was well for about 200 miles, and then it all came back.
I have four new TPMS modules on my desk, ready to stick inside the new tires I need right now, just haven't gotten yet. The original 2010 ones still installed.
After that, I'll re-attack the problem if it shows again.

 

I used to get that on occasion. Replaced the main unit (I forgot what it is called) and haven't had the problem since.

 

The only time I had that warning was when I tried to rig a 12V power outlet from the rear fusebox, under the center console, up to the arm rest. Maybe I was using bad wires or something but there appeared to be signal interference somewhere which tripped the fault.

If it persists you can always just turn off the warning on the dashboard via the red triangle button on the nav screen (which i just discovered - WOW)

 

I'm getting tpms system faults again... Thinking of trying to replace the module with a used ebay unit.

I've already checked wiring, antennas, etc...

Anyone know the part number for the module so I know I'm getting the right thing?

 

Google tells me it's C2Z1523, but check with your local main dealer to confirm as they ain't cheap and none showing up used currently on t'interweb

I replaced ALL of my components for new ones. All of them.
Four TPMS sensors. Four Initiators. Module. Receiver.
I still have the TPMS fault.
Next time I have SDD hooked up I'm going to disable it. That's the only option left.

 

Broken wire, bad connector, corrosion?
Yeah, you’ve reached the end of the easy stuff, tracking down a bad connection is a pain.

 

I forgot to mention......
I also chased all the wires. Well, maybe not ALL the wires, but power and communication wires are fine.

Also, corrosion probably isn't a thing, as atmospheric conditions around me are all anti-corrosion. I've never found any on any vehicle.
