The car consistently hesitates and violently jerks upon acceleration. Additionally, several times after a complete stop, the car will not accelerate when pushing on the gas. The engine revs, but it feels like the car isn't fully in gear (like riding the clutch in a manual transmission). This caused me almost to be rear ended when turning onto a 55 mph highway. The dealership has performed two software updates from Hyundai and the problem persists. I feel that the car is unsafe to drive and am currently driving a rental car while the dealership continues to fix the problem.

On numerous occasions (10 plus), the vehicle will not move forward while in gear and the accelerator is depressed. This usually happens at stop signs, when stopped in bumper to bumper traffic or waiting to make a left hand turn. There is no warning it just happens. Usually the RPM goes as high as 4000 to 5000 with no movement. It can take as long as 3 minutes before it decides to move forward at a reduced speed. The vehicle has also lurched and behaved erratically after some of the slow goes. These problems started with less than 1000 miles on the vehicle. I have had one instance of a no go and where it refused to move forward at all. It was towed to the dealership and they preformed a relearn on the transmission. The problems came back after a month. After the latest incident, my dealer claimed my vehicle was not safe to drive and they had me drop it off. It has been sitting there and they have put me into a loaner car until Hyundai comes up with a fix for the problem.

Like many others, I was stopped at a light. When it turned green, the car would not accelerate. RPM's went up, but the car stayed still. After shifting multiple times into reverse, park & drive, it lurched forward with a screech of the tires, but then still just crept along. Thankfully, the driver behind me was attentive, but I could have been rear-ended. This was the 4th time this happened in one day, but no one was behind me the other 3 times. I don't feel safe in this car.....and I loved it until now. Going to the dealer this morning, but not hopeful of a solution.

I've had an issue where on numerous occasions, my car won't move when the accelerator is pressed. Sometimes this happens when pulling out into cross traffic and I've almost been T-boned. Twice the car didn't move at all. I thought it broke down. I put on flashers, shifted it into park, then back in drive and the car started to go, but very slowly with the transmission revving up very high. The car seems very dangerous to drive as it responds differently to the accelerator almost every time. This usually happens after being stopped.

- Long Beach, CA, USA

We were stuck in a backup, stop and go traffic for about 20 minutes, when I went to accelerate the car would not move forward. I put the gear selector in park and back into drive, the car would not go forward. I had to step on the gas to make it move and then the air conditioner went warm. After driving for about 5 minutes the air conditioner started working again. I have tried to call the dealer for three days and they have not called me back, I think my next step is to call corporate Hyundai to file a complaint. This problem really needs to be repaired, otherwise this is a good car.

Transmission is slipping when accelerating from a stopped to start, or a rolling low speed to accelerating causing the vehicle to drift into intersection or lane without power. Attempts to re-shift into gear were unsuccessful. Car slammed into gear at high RPM while attempting to clear an intersection causing a jerking into gear sensation and accelerating very quickly. This has happened several times and getting more frequent. Took it to local dealer for service. Dealer checked for any mechanical failures and found none. Dealer acknowledged Hyundai is aware of a widespread issue with this model car and the dual clutch transmission not properly engaging. Dealer reset the learning mode of the transmission in attempt to temporarily delay the symptoms. The same symptoms re-appeared with a week. This is a dangerous scenario and I feel unsafe in this vehicle especially when in certain driving situations like making a left turn in a window of oncoming traffic and not having the power to clear the intersection or lane. This has happened and thankfully no-one has gotten hurt, ,,,yet! this car is only a month old and has 1000 miles on it. The first occurrence was on 7/18/2016 and is getting more frequent with time.

I bought this car in December and this problem started awhile ago. When at a stop its like the car is in neutral and RPM's rev but no acceleration. It is very scary to be in traffic and your car has no power. I put it in park and then shift back to drive hoping the car will accelerate. Finally when it does it jerks suddenly and then you have to brake in order not to hit the car in front of you. Driving this car now makes me very stressed and I hope I will not get rear-ended or worse.

Unable to move from a stopped position with the car in drive. Dual clutch accelerator issue with this model with no current fix.

On the evening of June 16, 2016, I was on my way home from work. I was sitting at a stop light at the intersection of two major roads and was the first car in line at the light. When the light turned green, I pressed the accelerator to proceed through the intersection and the car refused to move. For a moment I though maybe some how I had hit the shifter and put the car in neutral but I was still in drive with the rpms up to over 3500. Took a minute to put the car in park and then back to drive. After about 30 seconds, the car finally began to move forward and accelerate but the rpms were still high and the car was obviously not wanting to go. The car started smelling hot and finally proceeded. Scared me to death. I called the dealer right as it happened but the service department was closed. The next morning I was at the service department before they even opened. They kept my car for the day and gave me a loaner. I was told they could not recreate the issue and they "reset the shift points". I said I didn't feel safe in the vehicle even after that. They basically said there was nothing more they could do. At this time the vehicle had about 1800 miles on it. At 3800 miles, I took the car in for its first oil change and mentioned the same transmission issue to a different service advisor and said it was still shifting rough and just not smooth. He told me Hyundai is working on a fix but until then, I still think this vehicle is unsafe.

The contact owns a 2016 Hyundai Tucson. While at a stop light, the vehicle failed to accelerate when the accelerator pedal was depressed. The contact switched the gear shifter stick into park, neutral, and back into the drive position before the vehicle would accelerate. The vehicle was not diagnosed nor repaired. The contact mentioned that the vehicle had a delayed response when accelerating prior to the failure. The manufacturer was made aware of the failure. The failure mileage was 1,550.

Brought brand new August 2015. Many times the car lurches into gear. Several dct transmission hesitates noticeable when accelerating from dead stop. Car has 16,000 miles (but started around 1000 miles),. dct clutches periodically when at a dead stop will not engage, but once RPM's drop it will start to move, but prior it's like the car is in neutral.you have to wait until the RPM's come down and push accelerator again and then it will engage. Of course the dealer can not duplicate, so they say there is nothing wrong.. many times I was almost hit when turning due to the car not moving.. very dangerous and someone is going to get hurt or die!!! will Hyundai do something then, because its seems that after 167 complaints they still don't care to do a thing about it!! shame on you! since about 12,000 miles the car has been making a hissing type noise when accelerating, brought to dealer, they said its normal & that its the fuel pump finally being broke into the engine and that is very normal..they also lied on my work order that they compared that noise to a like vehicle with the same amount of miles and it did the same thing, however they told me on the phone that they would find me the same car with the same miles to show me its normal. Well that didn't happen, so they lied on the work order to cover their butts and to work against me when I contact lemon law attorneys. Who the heck are they kidding?!! brought to another mechanic & he said that is not the problem at all, but can't seem to figure out what it is..so im spending money to have them try & diagnosis it even tho I have a warranty. Tires (I think) causing the car to shimmy shake all the time at high speeds. They have been rotated & balanced 5 times & the passenger seat shakes like crazy, but again that is all normal they say. Shame on Hyundai for doing nothing about all these complaints!!!!!!!!!!!!!!!!!!

Dct transmission hesitates noticeable when accelerating from dead stop. Car has 13,000 miles, purchased new my me. I am retired and only driver. Dct clutches disengage periodically when at a dead stop will not engage again once brake is released and start accelerating, like car is in neutral. You have to set and wait and push accelerator up to 3,000 RPM then let off sometime-clutches engage and it jumps forward and you have to hit brake quickly or will have an accident. This happens periodically but not routinely enough for dealer to reproduce. It has almost jumped into oncoming traffic with me several times. [xxx] scary to drive.

The contact owns a 2016 Hyundai Tucson. The contact stated that the vehicle was slow to accelerate when the accelerator pedal was depressed. Also, the vehicle stalled several times. The vehicle was taken to a dealer who was unable to replicate and diagnose the failure. The manufacturer was notified of the failure and provided no repair solution. The approximate failure mileage was 100.

Brought brand new Jan. 1, 2016. Many times the car lurches into gear. Several times the car will not accelerate from a stop. Once, car wouldn't start. Dealer has had car twice (once for a week). No engine code. Blamed after market remote start, and removed it. Obviously, not the issue, as it has happened again twice in the past 5 days. This is very unpredictable and extremely dangerous, especially turning left in front of traffic. I have totally lost confidence in the safety of this car.

On 2 occasions I have come to a complete stop at a stop sign and at a red light. When it was time to go I pressed on the accelerator, the engined revved, but the car did not move. I had to put the car into park then drive several times before the car eventually moved. The car was put into the shop on 8/1/2016. The issue was not able to be duplicated, but the service manager called Hyundai tech and was told to perform a relearn. When I picked up my car, I asked about the service manager about the issue giving the numerous internet complaints. He stated it is a known issue and currently Hyundai does not have a fix. I am concerned about my safety while driving this vehicle giving the transmission issues. I am hoping something can be done in asap to prevent any serious outcomes due to the dangerousness of these transmissions.

Less than two months after I bought the car, with maybe 4000 miles on it, as I tried to back out of my driveway one morning, the car would not move. The engine would rev and the rpms would climb, it was only after several times of putting the car back in park and then reverse did it finally engage. After that, when driving slowly as in bumper to bumper traffic, upon acceleration it would seem to hesitate then lurch. The next time such an incident occurred was a couple of months later. I was stopped at a signal and when the light changed and I tried to accelerate, the car did not move, again. It took several times of putting it in park and back to drive before it would engage. It has happened several times since then. I find this dangerous and downright scary. Luckily, no one has rear ended me or worse. I have taken the car to two different dealerships. They say they can find nothing wrong and that no trouble codes show up. I see there are multiple complaints filed on your sight about this same problem, so something is wrong, dangerously so! would you please check into this for us.

On several occasions around town or commuting to work this car has not responded when pressing the accelerator. From a dead stop or when moving slowly the response is unpredictable. It happens randomly. This week the car's transmission warning light came on while going up an incline on a common curvy northern California road. It was a cool evening. This is a paved road. No other cars having a problem. I had to stop the car and restart it. Then while accelerating the car just stopped. No power, nothing, dead in the road. Had to wait and restart. This is very unnerving for any car and for a brand new vehicle is simply unacceptable. I have two little kids. I won't drive them anywhere in this car. It's not safe. I've driven motorcycles, manuals, automatics all kinds of makes and models over the years. The dead in the water feeling is the scariest, especially when making a turn from a stop to merge into traffic. This needs to be fixed or Hyundai needs to buy these cars back.

Multiple experiences after being stopped (red light, stop sign, fast food drive thru ) with the transmission remaining in drive and brakes engaged, when trying to move forward, the transmission doesn't engage. RPM's increase, but no movement in the vheicle. Then it lurches forward. Potential danger in a) being rear ended at an intersection light because the car will not move forward B) sudden lurching could potentially rear end the vehicle in front if I don't keep plenty of room. There was a software to fix this issue ((St.lf.usa.E478.150901: Sep 1 2015 12:00am). But it hasn't. I've experienced it 3 times today. Taken to the dealer on 7/2/16, they could not duplicate the problem. Told me that my gear oil was low and refilled. But am still experiencing difficulties.
