Had a small problem with my 07 Sonata so I took it to the dealer to get checked out. It was the throttle position sensor (TPS), something that has happened with some frequency according to the service manager. If was acting up at 66,000 miles, out of warranty. Codes were 2135, 1295
The dealer has been trying to get a hold of me for some time so I figured I at least give the salesman a shot at making me happy. He did. Given the miles, I was facing 4 new tires, brakes, filters, coolant replacement, and probably some other normal maintenance. Rather than invest $1500+ over the next few months, that bought me a 2010 Sonata Limited with everything new and a new warranty.
The new model has evolved a bit in three years. The heated seats now have a high and low setting, a third headrest (that will never be used) in the back seat better looking instrument cluster dual climate controls XM radio two settings on the trip odometer better settings on the auto door locks station seek button on the steering wheel radio controls
This car also had the optional Bluetooth too and that will be handy now that many states (including mine) require hands free now. The 07 came with Michelin tires, this has Hankook. No experience with that brand but seem smooth enough. Crappy weather tomorrow so I may find out more.
This is my first experience with XM radio too. My wife put on holiday music and is hooked on it over commercial radio.
The last one did well by me so I hope this one does too. It has been the best car I've ever owned as far as repairs go.
