As I was exiting my garage a couple of days ago, I noticed that several warning lights were illuminated (see photo). I immediately turned off the engine and restarted it, but the lights came back on. After driving for about a mile, I tried restarting the engine again. This time, after performing the usual System Check, all warning lights were extinguished and everything returned to normal. My guess is that I was parked too close to the wall in my garage, and that confused one or more of the sensors. This is the only time that I've experienced this problem with my 2018 Optima SXL. The lesson I learned is: always remember to leave a few extra inches in front of the car when parking.
