Upon suppressing the accelerator pedal vehicle fails to accelerate from standstill creating a 2-3 "pause" that is highly dangerous especially when entering traffic, freeways, etc. This is clearly a problem that is documented however no recall has been granted for this model. It doesn't matter what road: City street or a highway. The vehicle hesitates and does not move when you need to! when the powertrain does finally take hold, the engine revs high and pulses forward causing yet another disturbing and potentially dangerous condition for driver and others on the road. This is clearly a mechanical and/or software glitch that will eventually result in accidents and bodily harm. Note this condition is sometimes intermittent therefore creating a false sense of driver control since you never know when you will face lack of proper acceleration. At first I suspected it was just the 4-cyl engine being small, but after reading about other people having exactly same experience.

Car hesitates when stepping on gas.has caused several possible T-bones when taking a left in an intersection. Similar issues to the problem with the 2016 Hyundai tuscon. It is a chronic issue, not just a one time occurence.

I recently purchased a new 2017 Hyundai tuscon. I found that the vehicle doesn't shift smoothly, sometimes has a rough idle, feels like it's going to stall out, and doesn't always accelerate. I brought the car in for inspection for the rough shifting. The technician he asked me the following: Does it always shift rough, feel like it's going to stall especially in stop and go traffic, sometimes slow to accelerate? when I answered yes to all of them I was told that these are known problems with this car. He hears the same complaints over and over again. I was told there was nothing that can be done to fix it. Google "Hyundai tuscon dual clutch problems" and you will find hundreds of the exact same complaints. That day I drove to las vegas I was was almost in 2 horrific accidents because the car failed to accelerate and almost rear ended because it failed to accelerate. Not one week after the first inspection I took it back. He again told me that these are know problems with the tuscon. The lemon law states that I am entitled to a safe/ properly performing vehicle or a full refund of the purchase price. This car is most certainly not safe and not performing properly. I have been speaking with Hyundai who performed a so called investigation and decided that there is no evidence to prove my car is unsafe. After nearly 3 weeks they decided to have a field tech inspect this tuscon. That the rough shifting, rough idle, nearly stalling, and falling to accelerate are "normal" for this vehicle per their own mechanics. I have attached all email conversations between Hyundai and myself. They feel my complaint and safety concerns after nearly 3 accidents is unwarranted. I don't feel that I am being unreasonable by asking for another vehicle that performs properly or refund of my money and cancellation of my contract.

SUV ratchets forward from a stop, also has issues in traffic with being hesitant to propel itself forward. This has resulted in unsafe traffic situations as the powertrains ability to act as expected, has not been met causing delays in crossing roads or acceleration from stoplights/signs.

- Tulsa, OK, USA

This car stalls intermittently when accelerating from a stopping position to a moving position. I've stopped at a stop sign and when I push the pedal to accelerate the car pauses or hesitates. After a few seconds, the car thrusts forward, that that hesitation is scary and not safe. This also has happened whilst in traffic. As traffic builds it causes the car to make multiple stops. As I've gone to accelerate again I've had the car hesitate causing cars behind me to honk and creating an unsafe driving pattern. We purchased the car brand new, so this is really disappointing.

My 2017 Hyundai tuscon has a duel clutch transmission. I have had problems with it ever since we purchased it. I have had it back to the dealer several times. When you are sitting in traffic and try to go the transmission hesitates, when you come to a stop and go to take off the transmission is in the wrong gear and you get a bang. The dealer tells me this is like driving a car with a clutch I can drive a car with a manual transmission and I have never experienced anything like this. The car is great if you never have to stop and take off. Some days it's better than others. You can't drive this car like a regular transmission car you can't pull out for fear the car will not go or will be in the wrong gear. This car is not safe. The dealership never told us that this vehicle had this problem. I would have never purchased this vehicle if I would have known. This is a on going problem. Below it says when did this happen, it happens all the time.

The contact owns a 2017 Hyundai Tucson. On several occasions, while the accelerator pedal was depressed, the vehicle hesitated. Approximately 3-5 seconds later, the vehicle independently accelerated. The vehicle was taken to Hyundai village of danvers (24 commonwealth ave, danvers, MA 01923, (978) 646-8890) where it was diagnosed that the transmission was faulty and needed replacement. The vehicle was not repaired. The contact stated that the failure was intermittent. The manufacturer was notified of the failure. The approximate failure mileage was 1,000.

2017 Hyundai Tucson with dual clutch transmission hesitated to accelerate after stopping at a stop sign and turning right. When it finally did accelerate it was slow and unresponsive for a few seconds, causing cross traffic to brake behind me. The same hesitation and unresponsiveness can occur when going straight or turning left/right after coming to a stop. I believe this behavior is due to the dual clutch transmission.

I have been experiencing a lack of acceleration numerous times as I'm trying to merge into traffic on the highway and also as I try to accelerate from a stationary position waiting for a light and changing lanes also. Three months ago I took the car to the dealer and I told them of this problem and they said they will check it. When I picked up the car I was told that a reset was done to the computer to correct this issue. It is still happening. I have been in close calls numerous times and I don't feel safe for myself or others on the road because of this condition. I will be taking the SUV to dealer again this weekend to have them check it again. I hope that a recall happens before someone has a fatal accident because of this issue. SUV has 19500 miles.

The contact owns a 2017 Hyundai Tucson. The contact stated that the accelerator pedal was depressed, but the vehicle hesitated without warning. The vehicle was taken to advantage Hyundai (440 plainview rd, hicksville, NY), but the failure could not be duplicated. The manufacturer was notified and did not assist, stating that the vehicle had a dual clutch and the failure was inherent to the vehicle. The failure mileage was approximately 7,000.

- Fletcher, NY, USA

Periodically at stop sign/light the vehicle hesitates when accelarator pressed. Takes a few seconds to engage. Very dangerous when enterting traffic. Yesterday, lost power on interstate. Began to decelearte when I accelerated. The engine also began reving up and down without any change in elevation or accelartion. Before parking the car it barely had enough power to make small incline and engine malfunction light came on. Diagnostic testing shows no problems. Dangerous situation.

My 2017 Hyundai tuscon limited has a dual-cluth, 7-speed transmission that is unsafe and unpredictable. On countess occasions the vehicle has: 1)stalled completely for up to 5-6 seconds after accelerating from a stop leaving me exposed in the middle of an intersection and/or road with oncoming traffic almost causing several serious accidents, 2) randomly dropped out of gear at slow, rolling speeds with the accelerator is pressed, causing the engine to rev and then suddenly jump into gear almost causing several collisions, 3) dropped out of gear going up an incline, 4) stalling when pressing on the accelerator at rolling speeds almost causing multiple collisions. All of these issues happen very randomly, with out any warning, and in slower, stop and go traffic and/or when entering intersections. This is our only vehicle we use between my wife and I, and we no longer feel safe. We have taken it to the dealer several times and they have been unable to fix it. The service representative even stated that they do not know of any definite fix for this defect and safety issue. Hyundai now wants to replace the entire transmission with another dual-clutch, 7-speed transmission, which is not an acceptable resolution, as this transmission is flawed and unsafe. They refuse to buy the car back. Additionally, arapahoe Hyundai in Colorado failed to disclose this known transmission issue prior to me purchasing the vehicle. Had I know this, I would have never purchased this vehicle. It is also noteworthy that Hyundai is no longer installing the 7-speed, dual clutch transmission in the new Hyundai tuscon's, a clear testament that they know it is flawed and dangerous. They are being sued: Wylie V. Hyundai, case no. 8:16-cv-02102 the NHTSA should force Hyundai to buy all these cars back. It is a totally unsafe vehicle. Why hasn't Hyundai recalled this for all years!!??

My 2017 Tucson hesitates from a stop. It seems as if no gas is getting in. I've mentioned this to my dealership when I go for an oil change but they said it's the way the car is. I have noticed other people are having the same problem as I am. I think Hyundai should look into this matter and recall these vehicles with a fix. We have paid enough money for the brand new car and to have this on going problem is frustrating. Not good business for Hyundai because I'll think twice before I buy another car from them.

- Taunton, MA, USA

My Hyundai Tucson car hesitate to start from the signal light. I.e it took around 2 to 3 seconds to accelerate [I end up in applying gas pedal hardly to get the move from light ] and this had happened for 4 times so far from 2017 July to now. When I check with Hyundai service dealers on this problem, they said they have to check it completely and for that they would charge me for "vehicle inspection and diagnose" :(, I'm not ready to afford as this is not happening often.

- Milpitas, CA, USA

The contact owns a 2017 Hyundai Tucson. While driving 20 mph on a slight incline, the vehicle failed to accelerate when the accelerator pedal was depressed. The contact stated that she had no control of the vehicle and there were no warning indicators illuminated. When the vehicle reached the bottom of the incline, it was able to accelerate. The contact stated that the failure occurred at least four times. The vehicle was towed to jack carroll's skagit Hyundai (1313 goldenrod rd, burlington, wa 98233, (360) 757-7057), but the failure could not be duplicated. The manufacturer provided case number: 11361069 and referred the contact to NHTSA. The approximate failure mileage was 22,000.

My Hyundai Tucson hesitates when trying to accelerate. It feels as though someone is holding down the brake as I am trying to hit the gas pedal. It is very scary because all of a sudden the car will get this burst of energy and accelerate forward. This has occurred on multiple occasions while trying to take a turn at an intersection or pulling out of my driveway. It is very frustrating that so many people are experiencing the same issue and Hyundai does not have a recall. I have spoken to the dealership about this when bringing my car in for regular maintenance visits and have been told they will look into it. I have had zero luck with issue being resolved.

I have noticed persons reporting the same issue I have been experiencing: My 2017 Hyundai Tucson has been experiencing extremely dangerous acceleration issues that I would like to bring to the attention of the ntsb. The vehicle will experience lack of acceleration when merging onto highways and/or making turns that require acceleration. The vehicle has done this on several occasions where I was unable to control the vehicle with oncoming traffic, I would try to go and it seemed like the car would pause, and then the vehicle would suddenly accelerate. It is scary, I never know when this is going to happen, especially with my children in the car and for a possible incident with oncoming traffic. Not this has happened on several occasions at random instances. From turning, to accelerating from at a stop, turning, trying to accelerate on the highway. There is not common speed this is related to.

Some times car will not move though gas pedal is pushed from very low speed to accelerate. Happened numerous times to me and just bought car in Feb 2018. I have even floored the pedal which I have never had to do in any other car I've owned since I've had a license to get it to move. I made a 3 pt turn yesterday and getting ready to come out of it didn't want to move right away and a car was approaching me from behind on a side street leaving a festival. I've also made U-turns and getting ready to move into traffic it hesitates which is dangerous. It stops instead of going even though gas pedal is depressed. I don't trust car to move properly from slow speed to acceleration. I've reported it to Hyundai and called local dealer and they said double clutch but it needs to be fixed or a recall on it. I have read many of the same type of complaints. Doesn't happen all the time but enough times. It can be very sluggish and I bought car with under 10,000 miles on it just recently. For a turbo it seems strange way it reacts. This is my 2nd Hyundai. My 2012 Hyundai Tucson was fine. Never thought I'd have this type of problem for my 2012 performs well and is spunky. Not sure what to do. I plan to call dealer to take it in soon to see if they can do something. I thought Hyundai was safe cars too is why I was going for another one. To keep their reputation they need to do something and not keep selling these cars with known problem. I am an experienced driver but new drivers may take chances moving into traffic with this known problem. I some times make sure I have plenty of space before merging into traffic if possible. I hope it doesn't take a fatality for them to seriously look into this problem.

When accelerating from a stopped position, the vehicle would go into first gear and accelerate for a few seconds, then would try to move up to a higher gear and get suspended for about 5-7 seconds as if it could not find the next gear. This has happened 2-3 times so far. Also, when I have tested the response of accelerating by pressing the gas while traveling at a low speed, the vehicle would not respond as expected. On several occasions, I pushed the pedal to the floor and the engine only responded as if I was slightly accelerating. I have a 1.6 turbo. Additionally, I have had the lights on my dashboard go out - except for my radio/navigation system. I suspect this had to do with a sensor as it was dusk and my lights tripped some electrical or software defect. I was going down a major highway around Washington D.C. at the time and could not see any of the driving controls for approx 20 seconds. I am not sure if my headlights went out at that time but eventually, after flipping my lights off and on and pressing the dash light to maximum, the lights on the dashboard returned. Last week, the audio of my radio/navigation system would not work. After leaving my car and locking it for about 20 minutes and returning, the sound was working again. I took a video of this. The temperature in my vehicle was not regulating properly while stationary. The dealership said there was a bad sensor and replaced it. It has worked great since then. However, I am still having major problems accelerating from a stopped position from a red light or turning into a road, or accelerating from a very slow speed. My vehicle is now in a second dealership trying to resolve this issue that still lingers. This is causing me to feel very insecure about driving my vehicle. I am second owner. First owner had only put 2500 miles on it and traded it in. Probably a bad sign.

My 2017 Hyundai Tucson has been experiencing extremely dangerous acceleration issues that I would like to bring to the attention of the ntsb. The vehicle will experience lack of acceleration when merging onto highways and/or making turns that require acceleration. The vehicle has done this on several occasions where I was unable to control the vehicle with oncoming traffic. I have also been very close to being rear-ended and/or T-boned due to these acceleration issues. This is a very dangerous condition that is hazardous to not only the owner's of these vehicles, but also to other innocent drivers in their path. Apparently Hyundai and Kia vehicles are known to have this issue and have been mentioned in recent online forums. I reached out to Hyundai moments ago to address this issue with them and I am hoping they will respond to me with a fix and/or solution to this hazardous condition. My vehicle is going to the dealership again tomorrow 4/23/18 for this same issue. The last time I took the vehicle in for this issue I was told there was nothing wrong with the vehicle. It just happened again the other day and I was yet again put into a very "close call" situation. I have a young son and I do not feel safe in this vehicle with this condition occurring intermittently and unexpectedly on the roadway. How many people need to be hit due to this obviously known issue with these vehicles? my vehicle tends to do this more often when merging onto a highway where more acceleration is required; however, I have also experienced this problem when slowly accelerating from being stationary at traffic lights, stop signs, etc.
