The trip computer on my 2018 Sonata Sport keeps resetting a few hours after I turn off the engine. Setting the options to "reset after fueling" or "no reset" has no effect.
This began a few months ago, and it may have been after a battery replacement.
Any ideas?
Joe.

 

Hi Joe,
Some late model vehicles required the computer be notified of a battery change. Crazy things take place when this is neglected.

A capable scan tool might be able to get into the "Special functions" section and check what is going on.
