I was accelerating while entering traffic from a side street and the computer for the transmission put the transmission in neutral. I lost power as the engine RPM spiked up. The transmission was still in drive and the transmission did not engage again until I took my foot off the accelerator and then reapplied it. Aside from this problem being a vehicle defect, this situation could have caused an accident. I have taken the vehicle into the dealership twice for this problem since the end of July. The first time I took it in the dealership was able to reproduce the defect but they could not reproduce the defect the second time. Unfortunately this type of failure does not show up in the cars computer. Each time the car was returned to the dealership the transmission software was updated and the car was driven for a period of time as a relearning exercise. Obviously this did not correct the problem and without a failure code in the computer to pinpoint the problem the dealership is unsure which computer or component needs to be corrected. With this defect this vehicle should not be on the road because of the risk of an accident.

My husband and I were traveling North from palm coast, fl to slatington, pa. Traveling North on rte I-95, my husband drove about 300 miles and than I drove another 300 miles, stopping to eat and at various rest areas. Just before the Virginia border, we stopped at a rest area and my husband took over driving. He said we should stop for gas and a bit to eat. We went over the state line and got off at exit 4, we exit, stopped at the stop sign, turned right to go into the station and we heard a loud snap. At this point, the only way he could stop the car was to put on the emergency brake there was no control of the car. After being towed to the dealership, we were told that possibly the driveshaft snapped and the transmission also went. The mechanic there said that this is the third one he had seen like that. The next day we were told that in fact that is what had happened. Luckily, we had gotten off when we did, or else we may have been in a major crash on busy rte I-95 or may even had been killed because of no control of the car. This is 2010 car with only 17,700 miles on it. Today, we found out that Hyundai knew of the problem and that the dealers have received a bulletin about this. We were not told of this dangerous defect and now do not know if this has been corrected properly. We are supposed to pick up the car in Virginia by the end of the week. We do have a major concern about this car.
