This Hyundai Tucson was 3 months old when the transmission started to shudder and miss gears. I immediately took it in to Ken Garff Hyundai and the service advisor drove the car and said nothing is wrong with the car and that the transmission needs to break in and sent me on my way. The Tucson did it again while in traffic and the vehicle would not go and I had to put my hazard lights on and let the car struggle in changing gears to get it off the road. The car was towed in to Peoria Larry Miller Hyundai and this was documented by that dealership of the car shuddering and that they thought it was from my insurance plug in device. I explained that the car did it before the plug in. I removed the plug in device and the car continued to shudder. On [XXX] while backing out of my garage the car began to shudder while in reverse and i continued down the road while the transmission refused to change gears. It almost sounded aa if the car was in neutral and the car would on go no more than 3mp. I had the gas pedal floored and the car would not go. I reparked the car back at my home and called Hyundai for a tow. The tow came and the tow driver stated that the seemed as if it is in neutral as he drove it up on to the tow truck. After getting the vehicle to the dealership i was told from the service advisor that this is an ongoing problem with Hyundai's dual clutch transmission and this sounds like the problem.

On four occasions in the last five weeks, I have been driving at relatively low speed (20-30 MPH), and when I attempt to accelerate, the vehicle will not accelerate when I press the gas pedal. The tachometer shows the RPMs are maxed out, but the vehicle does not accelerate no matter how hard I press the gas pedal. I have to pull off the road, turn off the vehicle, and restart to fix it. I am certain I have not accidentally hit any buttons or switches each time. I have tried changing drive modes (eco/normal/sport) and using the paddle shifters and that has no effect. Cruise control is off, and no other speed limiting system is activated. There are no warning lights or indicators when this occurs. This is incredibly dangerous, as I am unable to get up to speed on a main road. A few instances led me to be unable to successfully merge onto a main road, which has led to me almost being rear-ended on one occasion, and the most recent instance I was in the left lane of a main road and attempting to pass a large truck and could not maintain speed. I was fortunate to come upon a slight downhill slope and was able to coast across the right lane and get off the road, but it was a near-accident. The dealer service center was unable to diagnose the issue, and therefore could not repair it.

Vehicle randomly keeps accelerating past the set speed when cruise control is set. Problem was first noticed in March. Have a video of the cruise set at 69 mph and the vehicle continued to accelerate to 87 mph before I disengaged it. Vehicle has been to two different Hyundai dealers for the issue but were unable to duplicate or find the issue. One moth ago were on a road trip and the cruise would accelerate to 8-10mph over the set speed on the cruise control especially after cresting a hill, then the adaptive cruise control would brake hard when approaching another vehicle. 0

I was driving at normal speed and all of a sudden the vehicle accelerated to a high speed. Took to dealer with all the other issues and they could not create the problem. They are trying to blame it on me for have two sets of mats. Also navigation unit is not the correct unit in car. When I apply the brake to stop it seems as if the frame is creaking.
