The car pulls to left since new. I had it checked at 11,000 miles and was told everything is in specification. I've just lived with it.
A transmission leak required a new gasket at 23,000 miles.
The wiper arm would not hold the blade to the window and needed to be replaced at 28,000 miles.
The cigarette lighter outlet stop working at 28,000 miles.
The exhaust manifold cracked making exhaust system very noisy. The manifold and catalytic converter was replaced at 38,000 miles.
The wagon hatch would not latch closed. The latch mechanism was replaced at 54,000 miles.
The driver side power window would not open or close (motor works) at 59,980 miles (whew! just shy of warranty end).
The paint is poor quality. It almost washes off the car with water!
I purchased the car mostly because of the warranty. I have had good service at my two local dealerships. Hyundai certainly lost money on me. While I haven't had to pay for these repairs they certainly have been time consuming and they do NOT inspire confidence in the car. I have never had a car with so many problems.
The car is usually very responsive and quick. The exception is when the car is coasting (low engine rpm) around 25-30 mph and you punch it. There is a very annoying delay while the transmission tries to figure out what gear it should be in. You could easily get into an accident if you assume the car would react with its otherwise great responsiveness.
