Hi everybody.
I am new here and recently I bought Elantra Sedan 2017. Everything was working fine and I wanted to change the oil but I noticed that digital odometer is problem. He counts kilometers until he reach 0.8 then he reset on zero again. And it is always like that. I tried to reset ECU but didn't help. Check fuses all is fine. Can someone help me with this please. Thank you.

I did. I also check the sensor it's working. Also went on diagnosed everything is ok. Only what is crossing my mind is maybe somewhere loose cable or connection. Because it's counting and when it's reaching 0.9 and to go on 1.0 kilometer he just reset on zero again.
