Just happened to me yesterday. 7000+ miles on my Tucson. I was waiting to go straight at a red light and when the light turned green I couldn't accelerate. Revved high but didn't move until I let off the gas a little and it seemed like the clutch finally engaged and I was moving at about 5 mph while still reaching high rpms. Cars yielding to make a left were waiting for me to continue straight. Luckily I wasn't trying to make any right turns at any intersection because I'd imagine a car coming at full speed could've hit me if I didn't pick up my speed quick enough. As I was attempting to get back to my work parking lot (all the streets were busy during the lunch hour), I was at a slight incline and the car didn't accelerate again as it should. I floored the pedal to avoid rolling backwards into another car and as soon as the clutch engaged my car peeled out and accelerated abruptly. The "transmission temp. Too high" indicator light came on. Luckily was able to make it to work. This happened once before but only once on one acceleration at a red light. I didn't think anything of it as it drove normal afterwards. Hyundai did the ECU flash update (as a tsb that I wasn't aware of) at the dealership a few weeks later and I thought it may have taken care of the issue. When it happened yesterday, it was much worse than the first time as it continuously had acceleration issues. After work, I drove very carefully to the dealership to drop the car off. It was a very dangerous situation and I hope they can get fix on this car. I love this car and it fits my daily needs perfectly. Hopefully, Hyundai can get this issue taken care of where all service departments are on the same page and get a tsb sent out to all owners who may own affected models.

No drive gear or reverse gear sometimes and sporadically, take off from drive or reverse. No power on take off it revs rpms.at an stand still at a corner or a red light or in traffic on a busy highway it just revs rpms you have to keep taking in and out of gear and hope youcan make it home without no one crashing into the back of you or car lunging forward into some 1 else.

Waiting at a light on a slight incline. Pushed accelerator engine revs and nothing. No power is transferred to the drive wheels. Tried several times. I thought I accidentally moved the shift to neutral. Nope. Tried again and just engine rev, no movement. Put in neutral and shifted back to drive and finally got going. Next intersection I had to make a left against opposing traffic and chickened out until the light changed to red. Same [xxx] thing occurred! could have been T-boned and whose fault would it have been" mine since there is no owning up to the issue with Hyundai and no indication of the issue recorded by the car's computer! no engine light or any other indication recorded by the vehicle that there is a problem. How many people have already had accidents due to this issue and were deemed at fault by their insurance? this link shows exactly what occurs. Watch and listen.

Car is a 2016 Tucson with the 1.6T engine and dual clutch automatic transmission. On 3 occasions while driving in slow traffic the car will not move after coming to a stop. The engine revs as if in neutral with no power to the wheels. After 10-15 seconds and shifting from park back to drive the electronic clutch partially engages enough to get the car moving again, but behaves like a manual transmission car with the clutch pedal partially depressed. The car does not display any warning lights or error codes. Took it to Hyundai dealer who advised it is a known problem but they have no solution. This is a hazard as it has left me stuck in traffic unable to move. Unbelievable that Hyundai is aware and offers nothing. Google search of "2016 Hyundai Tucson dct problems" hits over 25K search results. I see other NHTSA complaints on same issue.

After stopping at a stop sign, the transmission did not engage. The gears were grinding and eventually they snapped into position causing the vehicle to lunge forward. On another occasion, I was slowing down approaching a traffic circle, as I tried to enter the circle the transmission did not engage. Fortunately I had enough momentum to pull to the side to avoid being hit by on coming traffic. The final incident I had before bringing the car in for service (which is another story) involved an attempt to enter a highway after slowing down, where once again the transmission did not engage. Once again I was able to pull to the side to avoid a collision. This is definitely in my mind a major safety concern and I am not the only one to have this issue. My car has now been at the Hyundai dealer for 60 days "waiting" for a transmission to arrive with no arrival date available or eta of completion in the foreseeable future.

Issue has occurred 6 times. After coming to a stop at a stop sign on a city street, the vehicle will not accelerate when the traffic light turns green. The car is still in drive and the engine RPM's increase to 4000-5000 but, the car doesn't move. It feels like the parking brake is on (it is not) and depressing the gas pedal does nothing more than rev the engine. It's like stepping on the gas with the transmission in park or neutral.

As I was returning from lunch to work on a local highway the transmission started to slip and act abnormal. From stopping at stop lights to running the vehicle at the posted speed limits I felt I was going to cause an accident because the car just accelerated and slowed down. The rpms of the engine increased and decreased during this time. I am now, very concerned with my/my family's safety and others on the road because of this. This needs immediate attention because my car has only 4,000 miles. There are other people in the Hyundai forums that are complaining about this issue, which may not be affecting all vehicles but it should be a major concern considering the accelaration and slowing down issues I experienced today. Once I gathered enough courage to continue driving despite the error message and check engine light (see photos attached of error message and check engine light) I immediately took it to my nearest Hyundai dealer. Since I couldn't wait for my car I had the dealer representative drop me off at work. The dealer called me back about 1.5 hour later explaing that they reset the computer (whatever that means). I picked up my Tucson and it appears that resetting the computer did clear the error and the issue but I am extremely concerned for my life that this will happen somewhere on the highway since my normal home to work and back route has highways.

While stopped, with car in drive, pressing accelerator engine revs (4 to 5 on the gauge) but does not go forward. Car then jerks forward and then finally moves. I sat thru 3 red lights before the car actually moved. This occurs on city street this occurred once before but the forward motion "caught" quicker than the last time at the same time this occurred the ac failed as did the bluetooth. The phone said it was connected but the car said it was not. The ac fan worked but blew hot air. The ac and phone worked after turning off car at dealership. The tech at dealership captured on video the gear clearly in drive and the car was rolling backward. Service center said no error codes were recorded. Hyundai usa has no information to give me. Car has been at dealer service dept for 11 days now. Concern is safety of vehicle to myself and others with the sudden acceleration and car going in reverse while in drive.

Hyundai Tucson 2016,1300 miles. In heavy stop and go traffic on gw bridge, transmission overheating warning (pull over safely) car would not move, after 5 harrowing minutes was able to drive, taken to dealer, "never heard of this before" could not fix because nothing wrong. So much for,100000 mile warranty. Have since discovered someone else went to same dealership after I did, the manager, barry, said"I have never heard of this". so far no one has been hurt but it's just a matter of time. By the way, on my repair receipt there was a suggestion that I learn to drive properly!!!!!

- Longboat Key, FL, USA

The contact owns a 2016 Hyundai Tucson. The contact stated that the vehicle failed to accelerate when the accelerator pedal was depressed. The failure recurred intermittently. The vehicle was taken to the dealer where it was diagnosed, but the cause of the failure was not found. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 2,000.

I pulled into the drive thru line at bank behind another vehicle. I placed the Tucson into park, but left the engine running while the person in front of me processed their transaction. When it was my turn I moved the vehicle into park and pressed the gas pedal to move forward but the vehicle did not move. The rpms moved into the 3000 and 4000 range but the car did not move. Emergency brake was not on. Vehicle was in drive. No errors or warning lights on dashboard. I moved the vehicle into and out of park and neutral several times before the transmission engaged and allowed me to ease forward. I placed the car back into park while my transaction was processed. After my transaction was complete I placed the vehicle back into drive and attempted to pull forward. Once again high rpms and engine revving very loudly but not moving anywhere. I tried the shifting gears trick several times and it still did not work. The drive thru lane had to be shut down while I was trying to get my vehicle to move. After turning it off and back on a few times it finally worked and I was able to get into a parking spot. I called my husband. He arrived approximately 30 minutes later. He started the vehicle and drove around the parking lot. He reported that when the vehicle came to a complete stop (though still in drive) he would then attempt to accelerate and the engine would rev to high rpms for 3-10 seconds before finally engaging and causing a quick jerky jack rabbit start. Even with the dual clutch transmission, the previous 7,400 miles driven it would only rev to approx 1200 rpms prior to accelerating. Decided to take to dealership. Car turned off while removing items. When turned back on and driving to dealership problem did not occur. Dealership kept vehicle from Friday afternoon to Monday. They stated they were unable to recreate and that there were no error codes in the computer.

The first time I was at a red light, when it turned green and I pressed the accelerator the car would rev but not move. Tried a few time then had to go into park and drive again and then it worked. The second time I was backing up from a parking space and revved the motor 6 times and the car would not move. Had to put in park and then in reverse. It moved very slowly and was revving because I had to push on the accelerator more than I wanted. I was afraid both times the car would shoot forward (or backward the second time). The shifting is also strange in the car, it jerks forward when you press on the accelerator because it starts so slowly and then seems to jump into gear.

Tucson with 4139 miles, came to a traffic light, stopped, went to move, tach climbed to 6 grand and Tucson would not move. Shifted from drive to park a few times and the transmission finally engaged and the Tucson proceeded forward in a jerky motion buy finally smoothed out. Went another 600+ miles without it occurring again. No check engine light cam on and no diagnostic codes thrown. I contacted hyundia C/C by email explaining the issue which from researching, found that it is not an isolated incident. This is S serious safety issue that needs to be addressed asap.

I have 4000 miles on this car and already have had it in the shop 5 times! transmission- is very jerky, doesn't have pick up most the time, doesn't shift right away it takes a moment to kick in while RPM's are jumping. Hesitation from a dead stop, once at a dead stop and you slowly take foot off break the RPM's drop and the car shutters and feels like its going to die! dealer said its normal for a dual clutch because its like a manual and that I need to drive 2 footed or deal with it. I also had it to dealer say prior to this time, it's because the dual transmission is staying in second gear and that's normal and that's why it feels like its going to die. Transmission never shifts the same.. when in eco it worse and when in sport mode it very jerky and the shifting is awful and never smooth. Bottom line is this.. feels like the transmission has no idea when to shift and or how to shift. The RPM's go up but the car doesn't seem to pick up speed like it should as far where the RPM's are at, always revs up before it will even more. Also when at highway speeds it takes a lot to kick it down to pick up speed which is very dangerous. The vibration at higher speeds is horrible. Had tires rotated and balanced 2 times already and it till has not fixed the problem. Dealership doesn't seem to find T to be that big of a deal. Hwy speeds the cabin sound like you have one window open and you get that sound of being in a tunnel. Since day 1 when putting car in reverse and then to drive, there is a clunking popping sound from the back of car after it hits about 20 mph. Had that looked at 3 times and they can't figure it out. It is much louder and more often now with more miles deal says all my problems are normal and nothing they can do but to deal with it. Worst car I have ever owned!!!!! had in shop 6 times already in 9 months and Hyundai will do nothing to help.

Purchased January 2016 - limited AWD with factory installed tow hitch. Immediately noticed flickering interior lights and both head lights leaked, one side has been replaced. Later on developed hard start ups, shifting and acceleration issues. Along with intermitting front safety sensors and a glitching center console/back up camera. 7,500 miles in the ac stopped working from freezing over. Took to dealer while on vacation and discovered a melted fuse box cover and burnt tow hitch/ECU wires with an abundance of corrosion. Dealers could no confirm responsibility of the tow hitch harness, claimed it was not factory installed when it was factory installed and even on the original window sticker. We called Hyundai corporate everyday for over a week begging for help with no call backs. Roadside would not cover a tow to the selling dealer. Ended up driving ourselves an hour South to the dealer where it waits for a Hyundai engineer to fly in and look at it. There are recalls for this wiring harness in other models, the dealer wasn't even able to order a replacement part because it was discontinued. We were never notified of this and there are no recalls currently out for our car. We consider this a life threatening issue as the melting wires are a serious fire hazard along with the unreliable transmission and safety sensors.

I love my car and I just had it in for its 15,000 mile checkup last week and then on Saturday I am at a red light on a busy road and light turns green and my car won't move, it was acting like I had it in park but it was in drive. So I put it in park and then drive nothing so I did this a few times and then it finally went. I was very thankful that everyone stuck behind me did not get impatient. The car did the same thing later in the day in a parking lot and then the next day in my driveway. I do not feel safe driving this car. So Monday morning I called the dealer they said to call roadside assistance and have it brought to them. On Wednesday I went after work to pick up my car - they said they could not duplicate the problem and no error codes came up. I am actually nervous driving my car now, I am hoping that it does not happen again, but if it does and they do not fix it I will be getting another vehicle.

Vehicle does not move from a stopped positioning a city street has occurred randomly 4 times in first 2900 miles. Vehicles currently has 3100 miles. After stopping at a stop sign, I depressed accelerator to start moving again and the engine revs to 3000-4000 rpms, , but car does not move. It does not move!!!! release accelerator, depressed accelerator again and car jerkily moves forward after 4 to 5 second hesitation. Taken to dealer twice, at first visit no errors codes found and dealer attempted to explain away problem "as this is how the new trnsmission works, it has a small hesitation". second time at dealership last week for this recurrent problem. After stopping, engine revs but car fails to move. Again, no error codes found nor did car exhibit problem for service tech. Dealership told me to call Hyundai consumer relations to log the problem. This is a safety problem that NHTSA should look into as many other are also having this problem.

At seemingly random times, the transmission will slip completely out of gear and the engine will just rev but not move the car. Feels like the car is in neutral gear and just revving the engine. Almost got hit from a car as we pulled out to turn right from a stopped position at a stop light, pushed on the accelerator, and the car would not move at all. Just revved for about 5-6 seconds before finally going into a gear and moving the car. Very dangerous situation!! just went to the dealer to day to have it looked at and they said nothing was wrong and the car was "working as designed."

- Williamsburg, VA, USA

When stopped and hitting the gas pedal there have been occasions that the transmission will not engage and the vehicle will rev the engine as if in neutral. This has happened twice, once going uphill and I had to wave gars behind me to pass. 1.6T engine with the dct. The dealer says that this is the vehicle's way of not hurting the transmission. However it doesnt seem to me, an average driver who has owned many cars as if this would be safe or normal for anything moving on a road.

Purchased new tuscan and has 200 miles on it. My wife started backing up into our garage and warning light came on stating not to drive car due to transmission over heading. The car was towed to dealer. After a day they advised us not to drive the car in the eco mode as the tranny heats up. I'm concern that my warranty will run out and this was such a problem, it wouldn't get fixed. I'm sure all the tests for mileage was done in this eco mode. Plus someone needs to look into the fact when backing up, if you take your foot of accelerator the car rolls forward. Someone is going to get ran over this is a major flaw and needs to be addressed.
