Recently while driving the car seems to hesitate then has a minor acceleration. It seems as if its about to stall but catches and accelerates or increases to original speed. This is concerning especially when it occurs during rush hour traffic. In addition, I had to replace the battery at 24, 348 miles as the car died on me twice while traveling. I purchased a battery from o'rielly auto parts as it was closer to my home. The dealer would only state that battery failure has occurred with less than 30,000 miles on the sante fe however since I didn't bring my car to them the battery is not covered under warranty. It is unbelievable that battery life is this short.
