SLC Tower cleared us for takeoff Runway 16L on the RNAV WEVIC6 to HOPTO which is the first fix; RNAV captured as usual and at acceleration altitude autopilot were engaged and as PM (Pilot Monitoring) after engaging autopilot I saw the aircraft started heading to the left of course; PF (Pilot Flying) disconnected the autopilot and start hand flying; meantime departure key on the mic asking where we were going and we advised them with the situation. My observation on PFD the flight director were to the right; LNAV course to the left totally in disagreement with the right picture. After hand flying few fixes PF asked to re-engage the LNAV mode which at this point capture properly. Upon landing; Captain had the opportunity to speak with SLC Tower about the issue; which looks per the conversation it's been happening to several aircraft; a write up were made and maintenance came to fix the issue and tested the automation.Since this event happened to several different airplanes on the RNAV WEVIC departure it will benefit if tower clear airplanes on a heading then maybe direct to HOPTO till the problem gets figured out; the database or programming (coordinates) issue.
