Vehicle won't accelerate from a stop. When stopped and the gas pedal is depressed, acceration is extremely slow and after 3-5 seconds of depressing the pedal, the vehicle will finally accelerate as normal. It occurs with and without air conditioning on. This has happened while pulling into traffic and is a dangerous situation.

As reported by some others, after coming to a complete stop at an intersection, when I press on the accelerator, the RPM's rev up to over 4000, but the vehicle barely moves forward for about 5 seconds. This seems to happen during periods of high outside temperatures and only sporadically. This describes the exact same conditions that Hyundai recalled the 2016 Tucsons for in September of 2016. This is what Hyundai said then: "Hyundai says the transmission clutch application logic can cause a delayed engagement of the transmission when taking off from a stop." When I've taken the vehicle in for service, the technicians say that they can't replicate the condition, so they cannot pull a code and find a problem. This is a very dangerous problem when "stuck" in the middle of an intersection or trying to merge onto a highway or interstate. I have experienced both situations and it is not safe!

2017 Hyundai tuscon AWD limited purchased in March 2017, currently 6000 miles on vehicle. The dual clutch transmission (dct) hunts for correct gears on occasion creating hesitations and stalling effects. Several times (as many as 10+), starting from a dead stop at a light, the car will begin forward progress with normal depression of gas pedal. Power to the wheels will then completely vanish for moments of time (1-2 seconds) then the car will eventually move forward again. I've almost been rear ended twice due to this. I am lucky to not have been T-boned when crossing non-lit busy intersections. Type of gasoline used (regular or premium), drive modes (standard or sport), hard depression of pedal or soft depression of pedal, nothing seems to coincide with the these random occurrences. This is not the typical way a dct should operate. I have driven VW dct vehicles for years and have never had these extremely scary hesitation moments with them.

No or minimal forward movement when pressing the accelerator from a stopped position (in automatic). The operator must depress the accelerator almost to the floor before there's any acceleration (and getting high rpms). It almost feels like the vehicle is attempting to move forward in the wrong gear - there's no power/torque. This situation occurs frequently and is most dangerous when driving through an intersection from a full stop - especially when attempting a left-hand turn with oncoming traffic (but not limited to turns). The vehicle slows almost to a stall. These symptoms occur in all 3 drive modes: Eco, standard, and sport. However, I have never experienced these symptoms at night or leaving a garage in the morning. It appears to occur after the vehicle has been sitting in the sun for a long period, I.e, when the ambient temperature of the vehicle is hot. I live in Arizona. As added context, it should be noted that this is my 3rd Hyundai Tucson SE. The previous models were 2010 and 2013. I never experienced these symptoms with those earlier models. I have 3000+ miles on the vehicle and have more or less experienced the same symptoms since the vehicle was new.

Stopped at a traffic light. When light turned green, gas pedal was pushed and the car would not move much at all. The vehicle was in drive and the RPM's increased but the car would not accelerate up to any speed.

As others have noted, the dct seems to have a severe problem when trying to quickly accelerate from a stopped position. The car will generally creep forward a few feet at a very slow crawl of 1-2 mph, but will not actually take off until 3-5 seconds into pushing the pedal. This behavior of the car can cause you to be out in oncoming traffic for upwards of 5-7 seconds or longer. This is a very severe safety issue as a car should never have a delay in acceleration of more than 1-2 seconds let alone 5 or more. I have been in several near accidents due to his when trying to make left hand turns on busy streets appearing as I am intentionally creeping into oncoming traffic like I want to have an accident and not moving. I have taken the car to the dealer and one of the service individuals stated to me this is a known problem, but there is no fix. He suggested reprogramming the tcm (I will be making an appointment to do this when I have time to leave the car), but he did tell me he has not seen much success with the reprogramming or that there might be improvement for a short period of time with return of the issue. My wife will not even drive the car because she has no trust that she will not get killed in our area with busy streets. My father owns a repair shop in another area of our state and we are recommending to anyone to stay away from any of the Hyundai vehicles at this time as the company does not appear to care about safety if this is a know issue without a solution.

The dual-clutch transmission is incredibly dangerous, as it has an extreme delayed acceleration when coming off a complete stop or just intermittently while driving, in which the engine will redline in RPM. Parking lots are absolute misery as well, as the vehicle jerks heavily at low speeds. Another shocking issue with this transmission is that it will propel the car forward 3-5 mph even without pressing the gas pedal and going up a hill. It's hard to believe that this transmission is legal to sell to car buyers and I hope the NHTSA takes further action against Hyundai. I've only owned this vehicle less than 2 weeks and I'm going to be out thousands of dollars, as I can't drive this vehicle. I'm currently searching for the best option of remediation; please contact me if you need any additional information. I truly hope Hyundai does not get away with releasing such a dangerous product into their vehicles.

- Dallas, TX, USA

Vehicle hesitates after stop or very low speed. Accelerator fails to engage with a multii second delay that is especially dangerous making left turns with oncoming traffic. NHTSA now has over a dozen of this same complaint from all around the country. It's time for a recall! this is an extremely dangerous life threatening problem that needs immediate attention. Let's not wait until we start to see deaths attributed to this.

- Hawthorne, NY, USA

After stopping the vehicle does not respond to the gas pedal, severe lag. I have almost been in 3 accidents in 2 weeks, I am on blood thinners so this presents a life threatening issue for me, I am pursuing all complaint options and looking for a full refund. The car is only 2.5 weeks old and has less than 100 miles on it. The problem is intermittent so you can never be sure when it is going to happen.

The vehicle has a drive-by-wire system controlling the throttle and the 7-speed dual-clutch transmission. In certain circumstances, the throttle pedal has no effect on the throttle whatsoever. It happens most in 'eco' mode, but still happens in 'sport' mode, always at a relatively low speed (walking pace) or when accelerating from a stop. The vehicle has had one firmware update (at about 3K miles?) which did minimize the problem somewhat, but didn't eliminate it. At 7,900 miles the problem seems to be getting worse, and the dealer says there are no new firmware updates they are aware of. I am concerned because many times, when in slow or stop-and-go traffic, I've needed to accelerate and the vehicle simply wouldn't do it for what felt like forever, but was probably only a second or two. When the vehicle finally did start to move, it jumped forward at full throttle. The service writer at the dealership says this is a common complaint, and that other customers have also complained, specifically, about trying to pull out of their dealership onto a busy street and had their vehicle simply refuse to accelerate. On just one occasion, the vehicle accelerated at full throttle up to the engine's redline, without my foot on the throttle! as bad as it is, I expect that there have been accidents caused by this problem.

- Veradale, WA, USA

Vehicle hesitates when accelerating from a slowed or stopped pace (I.e. stop and go traffic, making left hand turns). When the gas pedal is pressed to go again, nothing happens. Then the vehicle slowly shifts into traffic before finally accelerating. Scary stuff when cars are coming at you. The issue is intermittent. The car also idles with 'jumps' or 'studders' occasionally with similar driving conditions. This is the sport model, 1.6T, AWD. The vehicle is not in sport mode when incidents have occurred.

- Minneapolis, MN, USA

During morning with in first few minutes the transmission gives up. Pushing the gas paddle only revs up the engine. The car does not move. This is a serious problem as car hesitates to accelerate and don't move. Happened so for 4 times in 3 months. Mostly happens in mornings. Serious issue. At one time I took a turn and car wont accelerate. Resume to normal after shifting to N and then to D. one time stopped and red light. The car did not move. All the people behind were honking. Turned off car and turned on; then all systems became normal.

- Centreville, VA, USA

2017 Hyundai Tucson. While driving my vehicle on a city street, I stopped for a red light and when I proceeded to move when the light turned green my SUV would not accelerate. The vehicle transmission made a noise, RPM's went to 4, car lunched forward and moved a little, then proceeded to drive.

- Baltimore, MD, USA

On Thursday, Jan 12th, after backing out of my driveway in my 2 week old 2017 Tucson, I put the car in drive and it didn't move. I took my foot of the gas then pressed again and it sputtered forward as if it wasn't getting gas. I stopped, put the car in park, waited a minute, then put it back in drive. It hesitated a bit then seemed to be ok. I have an appointment for some kind of "update" in 3 days. I hope this resolves the issue. In the meantime, I will depend on someone else for transportation as this is potentially quite dangerous.

- Pasadena, TX, USA

I just bought this 2017 Tucson limited a little over a week ago, have not even put gas in it yet, and I just had a scary experience of no acceleration from stop(s). Much as others have described it, when traffic light turned green I hit the pedal... to the floor and almost nothing (2mph)... about 5 seconds later it slowly began to rev into slow acceleration and I limped to the next traffic light and process repeated. As sitting motionless in a busy intersection is nerve racking, I just hope nobody would plow into me. I too regret this may be a hidden Hyundai issue, and have scheduled an appointment with dealer to try and address this safety issue, assuming they will reset computer.

- Hayward, CA, USA

We just purchased a 2017 Hyundai Tucson sport. The car has a serious issue of no acceleration after a stop, merging, passing on the highway and turning at an intersection. The car hesitates when you hit the accelerator, sometimes leaving you nearly stopped in a an intersection waiting for a car to hit you. If you choose to change lanes on a highway the car will hesitate when you press the accelerator to make the lane change. My wife has stopped driving the car due to the seriousness of no acceleration and safety concerns. We have taken the car back to the dealership and they said the diagnostics show that the car is fine and it is how the Hyundai transmission works in these vehicles. I think the car could be a "lemon." Not sure what to do.

- Willowbrook, IL, USA

The contact owns a 2017 Hyundai Tucson. While driving approximately 40 mph, the vehicle failed to accelerate and jerked rapidly. There were no warning indicators illuminated. The failure recurred several times. The vehicle was taken to the dealer, but was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage and VIN were not available.

- Scottsdale, AZ, USA

Transmission does not consistently shift through gears. Under acceleration, it will sometimes shift from 1-2- neutral instead of going into 3rd gear. If you deaccelrate and then try to acelerate as when coming to a turn, the car has extreme hesitation and sometime will just rev to 3,000rpm without any movement...again like it is in neutral. Dealership says this is all by design and I should adjust my driving habits to accommodate this dangerously designed vehicle.
