I've got a X1C6 and have the same problem since a few days. Tried reflashing and uninstalling/reinstalling the drivers in various combinations but didn't get it to work so far.
To be fair i'm not using Thunderbolt, only a ThinkVision P24h-10 which is connected via USB-C and seems to work fine so far.

I posted a while back that I was also having this problem. I periodically get this error message. At the surface it appears like it's just an annoying message because if you're not actually using all the functionality of the Thunderbolt module, then you don't see that something is broken. For example, when I drive my 4k monitor via the USB-C port with a USB-C to HDMI cable (Thunderbolt certified) everything actually works.
However, since I normally use an external docking station, the Lonovo Graphics docking station, which requires a fully functional Thunderbolt connection, I see that something is definitely broken. For many months this system (with the graphics doc over Thunderbolt/USB-C) functioned problem free. That was before I was getting these error messages. Then it stopped working (no longer displaying through the graphics doc) and I was getting these error messages. They trouble shooted the problem until they determined that the Thunderbolt module is bad and needs replacing. So I'm still getting these error messages. Any time I do a full fresh start of the computer, after using my computer for a few hours, it'll usually display the error message.
The challenge I see is this: Unless you have a system that enables you to see (or to show them) that your hardware has gone bad, you may have a hard time getting them to respond? What I don't remember is if, during their trouble shooting, it was also clear in the device manager that something was wrong/broken.
Finally, on friday the 5th, Lenovo will be replacing my Thunderbolt module. In a couple more weeks, I'll be back home to test and see if it's actually fixed. I'll keep you posted.

I too am suddenly strugling with this problem without an end.
No meaure of "delete driver, update firmware, reinstall driver" ever worked and it seems lots of us are frustrated with this issue.
After countless hours of trying this and that and researching what is going on, I am close to giving up and this dock will remain as $200 power adoptor. Don't have time anymore to continue digging this problem. Add me to the pool of very disappointed customers. What a waste of my time and money.
