The automatic transmission slips and then violently kicks into first gear when starting out. It will also slip while driving along and then kick back into gear with a bang sound. These slips seem to occur when the engine is cold( just started and temperature gage reads at or near c). I have taken it to the dealer 3 times over the years and they tell me they find nothing wrong. The problem recurs at least weekly.

Purchased new a 2010 hyundai santa fe, se. The problem that occurs randomly every few days is when accelerating slowly at around 20-30 MPH and the transmission slips out of 2nd gear effectively putting the transmission in neutral for about 1 second, and then will hard shift into 3rd gear making a loud bang noise. It can feel as though I was rear ended. This problem has been occurring since new and has been taken to the dealer multiple times where there the problem could not be replicated. This is the same complaint as with about 10% of the 140 or so complaints on the federal safety agency site for this year and model. There are at least 2 and possibly more tsb's that appear to address this problem (tsb-10-at-006, 12-at-012, 12-at-009-2). I will attempt to address the problem again with the dealer asking him to review these specific tsb's. After so many complaints about a very specific problem to a vital drivetrain component, it is time for hyundai to take ownership of this problem and fix it! The consumer should not have to go through so much hassle for a widely known issue. How many more people have this problem and don't take the time to report it?

The automatic transmission slips (goes into neutral) when shifting between first and second gear under light acceleration. The engine rpms raise during the slip and the transmission slams into second gear.

My 2010 hyundai sante fe gls transmission periodically slips and then clunks into the next highest gear with a force that shakes the car. This force translates into a banging sound. Each incident happened at speeds of 20-25 MPH and shifting from 2nd to 3rd gear. I am very concerned about the safety of this car since I don't know when the transmission will finally fail completely. I believe the car should be recalled for this potential safety hazard.

On my 2010 hyundai santa fe, the transmission intermittently slips, then slams into gear with such force that the vehicle lurches forward, and feels like you are being rear-ended. There are numerous other reports of this happening, however hyundai has not issued a recall for same, and the dealer has been unable to fix the issue.

I have a 2010 hyundai santa fe. The transmission slips and I get a hard shift with a loud bang when shifting from 1st to 2nd or 2nd to 3rd. It seems to do this when the transmission is cold but it does it even when warm. I had mine in 3 times for repair with a new transmission on the last repair. The new transmission is the same as the original one. Hyundai knows about this and they knew about when I bought the car. I should have been notified when I was buying the car - not finding out after the fact. The dealer gives me the deer in the headlights look when I complain about this like they have never heard about it before.

On a large number of occasions, the transmission of my 2010 hyundai santafe awd would slip into neutral as it went through the gears. That is when the car was still relatively cool as in the morning, it would start off in first, shift to second and then on some occasions slip into neutral. With a little on and off on the accelerator it would then go into third and then shift normally. The only times that it would happen was when the transmission oil was still cold. Hyundai changed the transmission computer per a service bulletin. When the condition reappeared it then offered to replace the transmission in its entirety. This seems to have solved the problem. My concern would be that if it did happen when one entered a line of traffic. This certainly could have created a dangerous situation. Till the situation was resolved, it happened on a significant number of occasions. Hyundai was responsive to the problem, and seems to have tried to address the problem. The vehicle has approximately 10,000 miles at this time. It was purchased new in april and the problem began in june. That at least is when we first observed it.
