As I was driving my family home from a soccer match in denver to our home in breckenridge my car(Hyundai, Santa Fe 2011) lost all power with out the engine dying. We were heading West and in the tunnel. It was extremely scary and put my family in danger. No warning lights have ever come up on my car before or after. This is the first time of many incidents that this has happened and not only when I have been driving but also my daughter, she has her permit! it doesn't just happen on the interstate but also around our community while driving. I have had it checked it out with my mechanic and they couldn't find the issue as the diagnostic came up with nothing. This is a serious safety hazard not only for myself but my family and others on the road.

My car started running hot periodically, the thermostat gauge kept going up and down. There was a bubbling sound in radiator reserve container. My vehicle would not stay cranked.

2011 Santa Fe leaks oil constantly. It's more noticeable when the car is stationary, because our driveway is always covered with oil stains. Others Hyundai models have been recalled for the same problem, but not the Santa Fe. The leak has been present for the last five years, ever since I owned the car. Dealer stated there was no problem when I first bought the car and noticed the issue.

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.

I bought the car in late March 2013 and the mileage was around 50,800. Every since then it periodically hesitates to accelerate from a stop or sometimes when the car is rolling forward very slowly. In every case the gas peddle (throttle) is fully released and when I push on the gas peddle, nothing happens. The motor does not speed up, the throttle is not engaging anything. Several times I pushed the peddle half the way to the floor, and nothing happened. Then all at once, it catches, and the car takes off at a high rate of speed. The car is not "coding" so the brunswick, ga Hyundai dealing will not repair what is wrong. And naturally it has not happened the few time they have driven the car. This is a highly dangerous situation that could result in death when pulling out from a stop on to a busy road. It is nerve racking to think, this might be the time the car won't move! I took a quick look at the data base of complaints and this same complaint is in your data base. Again it is a periodic happening which makes it more dangerous.
