2017 90D, 70,000 miles, FSD Upgrade, computer upgrade > 1 year ago. While trveling on the interstate, the navigation map suddenly switche to 3 or 4 miles away, stops in the middle of the interstate and instructs us to make a U turn. This has happened multiple times both on the interstate and off over the interstate. This is not rerouting for traffic. The map just suddenly puts us in a place that we are not and give directions to where we want to go with no regard for where we actually are. Has anybody else had similar problems? We have done all three kinds of reset w/o a change. It also picks up the speed limit for nearby roads when we sre onthe interstate and abruptly slows us down. Any suggestions?
