Intermittent acceleration issues. Upon trying to accelerate from a stop, the car starts to go but will not accelerate even with the gas pedell to the floor. This is a dangerous situation if you are trying to merge into traffic. As was the case the last time the vehicle did it, almost causing a crash.

Vehicle contnues under in motion city streeet driving conditions cause the vehicle to not move if the accelerator pedal is pressed and released repeatedly.exactly as recalled for other 2016 tuscon but this does not match VIN database. Dealer denies there is a problem and states the vehicle is being driven wrong quoting the drivers hand book which basically says the vehicle not usable in stop and go conditions.there are hundreds of simular complaints of 2016 tuscon that did not fit in VIN NHTSA or Hyundai database, or continued to have same problem after recall repair performed or dealers denying there was any recall.

The vehicle is Hyundai's new fuel cell model. On 3 separate occasions over 7 months the vehicle lost power while on a highway. The last occasion, November 7, 2016, I was in the left lane near the fast lane on the glendale freeway at about 9:30 am. The vehicle suddenly lost power and, since there is no left hand shoulder, I had to coast across several lanes of fast moving traffic to try to reach an exit ramp. After several minutes of not knowing what was happening to the vehicle, I gave the gear shift lever a nudge to the right. I heard a slight mechanical sound and the transmission re-engaged and I regained full power. The vehicle had nearly a full tank of fuel at the time. This same thing happened to me in the April/may time frame when driving on a highway in san diego county (about 1/2 tank of fuel) and then again in early July, 2016. When I was driving on the golden state freeway near griffith park (not sure of the fuel this time). Both times, without warning, the vehicle suddenly lost power. It coasted for several seconds but these two times -- after less than a minute -- the power reengaged, or self corrected, on its own. The November 7th incident lasted several minutes, and the engine did not self correct. On November 8th, I drove the vehicle to keyes Hyundai in van nuys. Since it had been over 4 months and several thousand miles since the second incident, I was not surprised that they could not duplicate the transmission failure. I do not believe the vehicle is safe to drive, however, and, since they have not been able to identify and correct the defect, have asked Hyundai to cancel the lease on the vehicle rather than continue to risk myself and my family in this vehicle.

I just purchased a Hyundai Tucson and it's not accelerating properly. It doesn't respond when you press the gas. I've had this vehicle for 1 week and it's getting worse. I'm scared this vehicle is not safe and may cause me to be in an accident.

7 speed duel clutch transmission is failing again after recall has been performed. Vehicle has started to go into neutral when pulling out into traffic leaving you in the middle of the road without being able to move for a short time. While driving the vehicle will now also lose power and shift into low gear on its own causing sudden deceleration. Vehicle will also chug forward when stopped at a red light. This is after all of the recalls and reprogramming of the vehicle has been done. We have now had three times that we have almost been hit, where other cars have had to slam on their brakes to avoid a bad accident and three other time I almost got rear ended because my vehicle started to go from after the traffic light would change and then stop moving. These vehicles with this transmission is a death trap and somebody is going to get killed! these problems are not consistent but they are real and dangerous! we are afraid to drive our new vehicle! it has been to the dealer 5 times for the transmission issues.

While in traffic slowly going up a hill on a city street, the car signaled "transmission temp. Is high! stop safely." I was unable to pull over for a few minutes because of the stopped traffic, then suddenly the car turned off! I was stuck uphill with those around me honking to move the car. After some time, I was able to turn the car back on and move forward. This continued to happen several times until I was finally able to park the car and turn it off. After a few hours, I turned the car back on and it was fine. I was notified by Hyundai that this is normal because of the dual clutch transmission and the information is in my manual. However, it does not say the car will turn off on its own! why didn't the dealer tell me this?! it is very dangerous!

- Lecompte, LA, USA

My Tucson slows down when I press down on the accelerator to speed up. It did this multiple times on my trip from Indiana to Colorado. This is extremely dangerous! I saw an upcoming recall which Hyundai does not have any fix for yet, but it appears to only be on specific ones with dual clutch. I don't think mine has that, but it definitely has safety issues and Hyundai will not assist me with it. There are multiple other issues with my new vehicle also which I cannot get assistance with and have filed multiple complaints, multiple places.

- Seabrook, TX, USA

I took my 2016 Tucson into the dealership on 9/23/2016 to address the dual clutch transmission recall. Prior to that, my Tucson would randomly jerk, not accelerate when pressing on the accelerator, and the rpms would go haywire. Now, 10/12/2016, after I took it in for a recall, I am still experiencing the same issue. It's happened once in slow traffic, and just this morning on the highway on my way to work. This time however, the Tucson's rpms went from the 2X area to the 4X area without provocation, causing the Tucson to drastically accelerate, almost causing me to rear end someone. This was without me manually accelerating. At this point, I feel like I'm driving a deathtrap and am utterly disappointed that Hyundai has done nothing to truly correct this issue.

- Cheektowaga, NY, USA

This vehicle seems to take off in third gear, shaking every time and stalling sometime. It has completely shut off at red lights and has stalled pulling out into traffic. The dealership has done 4 updates trying to correct the issue but it still occurs. All management of the dealership have driven this vehicle and agree that there is definitely a problem. The service manager put his foot on the brake and the gas as a demonstration to me and the vehicle dies out every time. They do not know how to fix the problem. The recall due out on October 28, 2016 was already done on September 27, 2016 and did not correct the issue.

- Prairieville, LA, USA

This is my second complaint on this car. There has been previous problems with the transmission slipping and the car would not move. The car would suddenly lurch forward or backward if you were backing out of a parking space. We took our car to the dealership for service on September 20, 2016 while it was there two recalls were taken care of. One was recall 149 which is supposed to fix the problem. The other was for a hood latch. Since this service work there have been additional problems with the car. I began keeping a log before the last service work. Same type problems as before the recall was taken care of. Today, my wife called me in a panic about the car. She had tried to pull out on a highway and the car revved up but did not move. She said the car suddenly lurched forward very abruptly so much so the traction control light came on. She is scared to drive the car anymore. I called tameron Hyundai and spoke with randall in service. I explained the incidents that had happened since the recall. He asked if we could bring the car in today. We could not due to work reasons. I will be taking the car to the dealer tomorrow. Not sure what they will do or say. I too am very concerned about the safety of driving this car.

Problems with vehicle since purchase. Brought cat back to dealer for repair 4 times, but problems still remain. Prior to last software upgrade, car would not accelerate after stopping, would jerk without warning, slow going up hill, would roll back, and would stop and then propel forward. Once last recall (3) done, the car still in not driving appropriately. Car runs rough, still jerks, still slow to go up hill and still intermittently stops. Transmission warning (over heated) came on, yet the computer did not make note of it when read for problems as if it never happened. Car is unsafe, is not driving as expected nor as it should. Gas mileage is also very low, considerably lower than what was promised upon purchase.
