One problem related to battery dead has been reported for the 1998 Hyundai Sonata. The most recently reported issues are listed below.
Same as odi id number: 1003666 . Front doors do not unlock from inside or outside and must crawl through back seat to get in to the front seat. Passenger side door stuck first and passenger had to get out the window. Two weeks later drivers side stuck. Two weeks later parking lights were left on at work and doors were locked. . . Battery died . . . Door locks are electric. . . Front door key only unlocks back doors if you have a good battery! couldn't get in car to open hood to jump battery. . . Had to leave car at work for days trying to get hood open with stiff wire and finally was successful when thick enough wire was used. Don't dare to lock car up again. . . I still find it locked up many times a week. Must be self-locking. Dealer told me this is a safety hazard and will not pass inspection. Dealer told me parts are about $100 for each door and $200 labor for each door to cut through the interior panel to get access to open them so they can work on them. That's a $600 fix that can happen over and over again because manufacturer used cheap plastic parts in the locks when they shouldn't have.
