My office mate just got the 2011 Sonata a couple months ago. She loves it, though there was a recall, something to do with the steering.
As for the Jetta, I had a 2002. First year they had moved production to Mexico. Had a lot of electrical problems. From what others on this string have said it sounds like they have since fixed those problems but I'll never own another VW. Currently have an 07 Civic. No problems (first year of the new body style, often times this leads to a recall or two.)
