Driving ca i580 westbound, bright sunny day (2:45pm 9/24/19) in 2012 santa fe with 111k miles on it. Going highway speed, without warning (no knocking, no acceleration issues) the engine shut down: oil, battery and engine lights illuminated. Having no power steering, I muscled the car down the nearest off-ramp (coasting 3/4 mile, I was lucky to be in the far right lane). I had also owned a 2011 sonata that went thru 3 engine failures with symptoms (each time, acceleration issues, gearing hesitation and knocking occurred). With the santa fe, no such symptoms, it just shut down after running perfectly. I called roadside assistance and they tried to jump start the car -- no luck. A tow truck took the car to a local hyundai dealership in dublin, ca. They determined that the crankshaft was frozen causing an engine seizure. I asked if this car was covered under the various engine recalls that have plagued numerous other hyundai models and they said "no". So it seems I am another victim (4 times over; the sonata was lemon lawed) of hyundai's engine shoddy manufacturing issues. I am awaiting the hyundai service department's official report and cost analysis. I will be contacting hyundai america's customer service tomorrow.

This vehicle has a problem with stalling and hesitation when coming out of turns and at speeds between 60-80 MPH. I have mention this to the dealer several times and they continue to say they cannot find anything wrong. Because there is never any lights on and no codes. This is a very bad problem someone is going to get hurt from this or die from this. But no one will know because the symptom will not show up as a code on the system, if they die the story cannot be told. Please look into this, I bet if you check with owners of this vehicle you will find the same problem not only the same yr of mine but newer ones. This problem has been happening ever since I have owned this vehicle. I have now a 109,000 miles on it now. On 01/28/2018 it done it several times on the highway.

We experience a feeling of loss of power and almost stalls while trying to make left or right hand turns from a complete stop. It has happened since we purchased car in 2012 but so intermediately that we would just try and explain it away (we came up with oh - we are traveling in the mountains, got bad gas, weather hot, weather cold, maybe I imagined it) but when I almost got hit in the side took it in to dealer again. They have had it 4 times for the same trouble and until the last visit could not duplicate it - dealer in june 2014 kept car many days and then I received a call from service manager who asked if I braked left footed - well yes I do as my husband does. He said they could duplicate the problem only when they left footed braked and their solution was to not do that. I asked some more questions, basically why that would make a difference since we have always done it. He said since the toyota problems the sensors in cars are more sensitive? I told him there are over 80 complaints with the odi for same problem in 2012 santa fe - he said oh that is a different problem - I read all of them - trouble sounds the same to me. We researched this car before buying - nothing in their advertisements, paperwork or on the net said left footed braking will cause your car to stall - we would not have purchased it however, I am not even positive that is the problem. I did also open a complaint with hyundai - they denied a claim of a lemon car and said to just to stop braking left footed. The letter said they drove it 200 miles with no duplication of trouble which is not what the service manager told me - they were able to duplicate it. We now have a car I will not drive because it is dangerous and who would buy it since we would have to disclose this hesitation problem. Just rec. Letter from lawyer asking us to call him - have not yet.

Just bought this car two months ago. At random, and when making a left onto a busy street, accelerating from a stop light, there is a hesitation and a very quick shut down when accelerating. It re-engages just in time to prevent a potential crash. I talked to the hyundai mechanic about this. They test drove it, but since the problem is random, it would make sense that they weren't able to detect it during the test drive. The problem isn't major for now but all it takes is one event to make it so. I was relieved to see other complaints of the same problem on this website.
