Loud Engine Noise problems of the 2011 Hyundai Santa Fe

My 2011 Hyundai Santa Fe was being driven on the city streets at a speed of approx. 30mph when the engine starting making a loud noise in the engine. Found the engine has a bent rod. The car has 110,000 miles and has had a regular oil change ever since we bought the car. Has anyone else had this problem. All other vehicles I have owned or own now last well over 200,000 miles. Had to tow the vehicle home 80 miles. Hope this doesn't happen to anyone else. Never had a warning this was about to happen. Thank goodness he was on a city street. .

On 3 separate occasions my vehicle would rev up the rpm's and then slow way down and vehicle paused for about 5-10 seconds then reengaged. Also, the engine seems accelerates and slows down on its own, doesn't feel like taking fuel at times. My complaint sounds similar to NHTSA id# 10744564, however, my vehicle did not make a loud sound from underneath. I have had my 60000 mi service completed and issue presented afterwards. Luckily, these 3 incidents happened on low volume traffic streets. I have had service after at different Hyundai dealers without explanation.
