Never had this happen to me. Admittedly I am in a very rural area, and while I do sometimes get some gps points that are "off" it's generally very fast and accurate. Basically all the errors I've personally run into fall into what I'd consider acceptable margin of error.
Even in heavy tree cover on a remote island for a hike last year. It (Garmin Instinct 2X) was incredibly accurate.
