This is the fourth time in the last few years where my "Needs Service Soon" light pops on (the car icon with an exclamation point bisecting it vertically). However, before I have a chance to get it to the dealership for diagnostics, the light goes off. Almost every time, it stays on for approximately 12-24 hours and then it reverts to being off. Anybody experiencing anything like this or have any suggestions? My car is a 2016.
