80mph restriction?

I’ve been driving my truck for 3 weeks now and enjoyed the instant speed available especially on the highways. Today out of nowhere I got a warning at 75mph that I was approaching my 80mph speed limit restriction. I have not implemented anything new with my preferences and have sped above this speed many times before. I’ve checked the “my key” options that are referenced on the warning screen but nothing is listed about an 80mph max. I have the local speed limit sign recognition option turned off.
Anyone else experience this (perhaps an update casually?) and how do I turn it off? I is amazingly annoying and distracting while driving on the highway.
