Also have had two Sonata's - different car, but equally dependable.
Yes I've had Sonatas since 1999 (EF & EF-B V6s + EF 2.0L 4cyl). Bought two of them new and two used. Very few problems over the years, good warranty response on the new ones, back in the day. Still not losing oil, despite all being over 20yrs old & 300,000kms. Those G6BV engines are pretty solid, and the bodies have all lasted quite well too. The EF-B has even written off two Ford Falcons. In the first instance, my bonnet/hood, and front bumper need minor panel beating/repair, while the second time all that was needed was a respray of the rear bumper LOL!! Very solid cars.
Had some solenoid issues with the two EF automatics when approaching 300,000, but apart from the inconvenience of that, the trannies are still going well.
