I was coming off the highway on the off-ramp and coming to a stop at a stoplight. When the light turned green, the car wouldn't not accelerate pass 10 or 15 mph. It seemed like it wouldn't shift to a higher gear but would be stuck on 1st gear to accelerate. I had to pull off the side of the road and get it towed back to the dealership. Before getting a tow truck, I attempted to turn it off and on several time. The check engine light would come on and any attempts to restart and accelerate the car would produce the same results; the car wouldn't accelerate. Also, after turning off the car, the car would not come on without a lot of engine cranks. The car only as 823 miles on it. I've only had it for 2 weeks. Extremely disappointed with the car and the company. Will try to return it. Not worth the risk of it causing inuring to my family.

6/10/13 while driving 45 mph with outside temp around 90 degrees my air conditioning stopped working. Tried turning off and on but would not work. Pulled to the side of the road turned the car off and restarted and the air conditioning worked again. I thought it was just a fluke. 6/28/13 while driving 65 mph on the interstate the car lurched and the rpms went up and down. I pulled to the side of the road but no lights were on and everything looked normal. I pulled back on the road and took the next exit. At about 35 mph the car started hesitating and then died. I coasted to the side of the road and it restarted on the first attempt. I was close to my destination so I drove there and called Hyundai assurance. They towed the car to the closest dealer and they have had the car for 3 business days and have not been able to duplicate the problem and the computer shows no errors. They said they would probably have to have a field engineer to come look at it. I don't know yet how long that will take. I loved the car until this happened. Now I don't think I will feel safe if they can't find the problem and fix it. Am I just supposed to keep driving it and hope this doesn't happen again and hope that no one is hurt next time.

I was driving my 2013 Santa Fe on the highway on April 6, 2013 and I was coming to a four way stop. I heard my engine start making a ticking sound. When I went through the intersection the noise was even louder. At that point I pulled off along side the road and called roadside assistance. My car was towed to the dealership and on April 8, 2013, the dealership called me and said that the engine had blown up. How does an engine blow up on a brand new car. This is the second incidence I have had with this car. Last month the axle broke on the vehicle. For me I don't feel it is save to drive anymore.

What I am about to describe happens randomly. The only discernible pattern is that it happens when accelerating from rest or from slow speed. It has happened about 15 times in the first 800 miles of driving. When I begin to accelerate slowly forward from rest or from a slow forward roll there is no response. It feels like the engine has stalled, but hasn't. continuing to push down brings no result. After approximately a 2 to 5 second delay, the rpms begin to build up rapidly. The first two or three times it happened I suddenly surged forward in a very dangerous manner. The real problem, however, is that with following traffic expecting me to accelerate and continue to accelerate and I suddenly stop accelerating without having applied brakes, thus activating brake lights, there is a rear end collision waiting to happen. Here is an example from last night. I was rolling slowly in a left turn lane, foot off the gas, waiting for oncoming traffic to clear. It did and I begin the turn simultaneously pressing down on the pedal--no response. Let up and pressed down again--no response. I let up again, rpms came up, I pressed down again and proceed normally into a parking lot. I was perpendicular to 3 lanes of oncoming traffic and dead in the water for maybe 3 to 5 seconds. Essentially the same thing has happened while accelerating out of a U turn and also coming out of a slow right turn. It happened while accelerating slowly through an opening security gate. I have left the car with the dealer overnight so they could drive it and hook it up to their error code machines. They could not observe the issue or diagnose the problem. Nonetheless, it is real and very dangerous. It has been a matter of pure luck that no one has been close behind me during any of these power losses. I hope this report is useful. I would be happy to talk to anyone who might want more information.

Vehicle will not fill past 3/4 tank. If you stay at pump and keep clicking it will overflow and eventually fill but, then engine light appears and must to return to dealer for service. Many parts have been installed in an attempt to fix but nothing works. Electronic steering exceptionally vague in any of three settings, trailer connector not functioning. Vehicle engine almost cuts off at times.

2013 Hyundai Santa Fe. Consumer states issues with hesitation and stalling when accelerating. The dealer informed the consumer the problem was caused by electronic fuel injection, which was common among several brands of automobiles and there was no fix for the problem. The hesitation at acceleration occurred at slow speeds while turning and the engine would momentarily stall.
