I bought this car because I had no choice - it was the only one available that I could afford. It has given me nothing but problems - the brakes went out (twice), it rattles terribly, it stalls when the a/c is on (and sometimes when it's not), and the interior fogs up when the heat is on. However, it does get good gas mileage and it is comfortable. But I will not buy another Hyundai.
I had problems with my auto transmission, I did not have the transmission coolant flushed, so it overheated eventually and killed the transmission, bought a new one, still going strong. Had a fault with the auto door locks, sometimes they would lock without warning when I got out of the car, locking my keys in. The brakes have lasted forever on this car, confortable ride even on the worst frost-heaved roads. My only complaint has been expensive parts/ unavailability of parts. Right now I need a valve cover gasket, and none of the dealers can get it for me.
My father-in-law gave me this car with about 100,000 km. It's not the nicest car I've ever driven, but it is VERY reliable. It has never broken down on me. It starts up in the snow and cold no matter what. So far, all I've replaced has been a battery, distributor cap, and plugs. Getting work done on Korean cars in Korea is dirt cheap, so that is a plus. Same problem with power door lock gremlins. They lock and unlock on their own all the time. When I get out without my keys, I make sure to roll down the window first! It has 155,000 km. (nearly 100,000 mi.) on it now and should be strong for much more.
Bought new and still driving 9 yrs later. Fun to drive, especially at 190km/h. Had front crash at 80 km/h miraculously nothing happened to us, car took all the impact and was severed. Mechanically excellent and snappy. Body mouldings rust inside and swell - had to replace 2 times. Door locks rust & freeze, takes time to get in - can turn the key, however can't open. Hardware falls apart (sunshades, door knobs). Upgraded stereo to Hyundai CD combo - far much better sound. A/C still works well. Fuel tank rusted - had to rebuild. Manual tranny rebuilt in 5th year, wheel bearings noisy. Overall quite positive experience
