Every single car you buy has it's querks.
What I would do, is not to be speculative about what's going to happen because of the brand and make of the car.
But more to the point what is going to happen to the car because of how the previous owner treated the vehicle, i.e driving conditions, types of fuels used and most importantly service history.
Generally the word is these are very reliable vehicles. Good maintenance and driving within the vehicle's ability to perform are key to getting the best return on your investment. Its certainly not the most powerful vehicle of its size but if you can live with that you should find owing one a very satisfactory experience.
Whats the mileage?
Is it automatic or standard?
Good news is that you've still got plenty of warranty left so if you do have a problem you should be able to get it fixed at Hyundai's cost. This is where service records are going to be really important to ensure the previous owner hasn't done anything to void the warranty like not keeping up with regular maintenance.
Hi Cindy.....enjoy your new car!
The single most important thing you can do is to keep the oil up to the MAX mark on the dipstick (check it weekly) & have the car serviced on schedule (make sure they stamp the service record!).
