Hi,i have on 07 tuscon and havent had any problems with it,the only things ive done is to add a trailer hitch and trailer wireing harness.the esc has worked once or twice and not caused me any concearn.i only wish my tuscon had come stock with the crossbars for the roof rack,two hundred bucks for the two bars is just to crazy for me.i get 20mpg wich is ok since i dont drive much,i did notice the tuscon is rather heavy,at the dump i think it weighed like 4500 pounds with my small utility trailer and very little on it.probly explains the low mpg for such a small vehicle.i wanted a station wagon with good ground clearence that could haul my family of five around and tow a small trailer with a reasonable load on it(under 700 pounds)and thats what i got.i have a relative who worked at a hyundai dealer when i got the tuscon and she told me they almost didnt come in for any repairs.i plan on driving mine for a few years and well only trade it in if i can find a similar vehicle with a diesel engine.
