My 2014 Hyundai Sonata GLS has all the dashboard lights come on. Check engine, traction control, airbag, tire pressure, everything turns on. RPM and MPH gauges goes to zero. Gear indicator goes blank. The cars power seems to stutter and I have trouble accelerating and shifting gears with the transmission. Tried to hook up to a OBDII scanner and got an error saying unable to connect. Anyone experience this issue on their vehicle? Would rather not take it to dealer as I’m out of the warranty. Any ideas? Attached an image of the issue. Couldn’t post the video as the file size is too large.
