I have a Hyundai Tucson SE plus 2.0 liter has almost 21K miles. I started noticing an issue a few weeks ago where it will not accelerate from a stop or slow crawl. I've had some frightening situations where taking a left turn in an intersection there is delayed acceleration as much as 2-5 seconds with on-coming traffic. The problem is exacerbated with the ac on and undrivable unless I turn the ac off at the stoplight/stop sign. I've tried adding sea foam to a full tank of gas thinking it was dirty fuel-injectors, but no improvement. My brother has an identical car with 31K miles and called me today of having the same issue. The only common denominator is it has been hot (85-90 degrees) during the day. When the temperatures are lower in the morning, I do not notice the problem as much, but it remains sporadic. Also, I experienced the car shifting at unusual times. I recently had an oil change at the Hyundai dealer, and I mentioned the issue. They could investigate the problem for a price which I was not inclined to do, mainly if no code was triggered and it is under warranty. My brother is taking his Tucson next week, and I will wait to see what comes of it. It is not a coincidence that two identical cars would experience the same issue at the same time. Having read several complaints on NHTSA and other forums, I believe this is an issue Hyundai is not addressing. If Hyundai can't fix this soon, I will turn the car in when I lease is up in a year.

I've had a problem with the car hesitating and stalling since I purchased it in 2017. I brought it to the dealership where I bought it and they told me they did 2 service recall repairs on it but could not replicate the problem. The issue continued to happen so I tried first Hyundai in North attleboro. They told me they also could not replicate the problem but reset engine adaptive values and transmission adaptive values and to keep an eye on it.. today I tried to merge into traffic on the highway, the car began to hesitate, then it started buck and to smell like something was burning. A short distance up the highway the car completely stalled out and wouldn't drive. I was left stranded on the side of the highway for over an hour while waiting for a tow truck.

After a stop, initiating a left or right turn, the vehicle does not accelerate, the tachometer races, but there is no engagement. After a long pause, the transmission engages and the car jerks forward. The problem is intermittent, occurring at least twice a week for more than a year. Hyundai service denied there was a problem on multiple visits before finally admitting the dual clutch was faulty. Clutch replaced, problem persists, and they claim there is nothing further they can do.

There have been countless times, that our 2017 Hyundai Tucson has had trouble accelerating in low gear, whether coming to a stop at a stop sign or red light and then trying to accelerate or when trying to accelerate from a slow speed (5-10mph). Most often times, when pressing the gas peddle to accelerate it is very delayed, almost no acceleration response for about 5 seconds, and then it is very jerky getting into gear at that point. I finally had enough of this when my wife and I came extremely close to getting rear ended (the vehicle behind us came screeching to a halt) as there was no acceleration response when I pulled onto a 50mph road after stopping at a stop sign. The 2017 Hyundai Tucson is not safe to drive until this acceleration issue is fixed. I have done research and seen thousands of other complaints on this same issue for this same exact car. Further, Hyundai had a recall for the same issue on the 2016 model, but they did not fix the issue for the 2017's. I implore the NHTSA and Hyundai to make this a recall! do the right thing for your customers Hyundai and save people from some bad accidents and potential loss of life.

Transmission fails to engage on some occasions when attempting to accelerate from a stop or accelerating into a turn at an intersection. Acts as if the transmission does not know what gear to engage. Dangerous when attempting a left turn as you stall part way thru the turn. Have had car back to dealer twice and they claim no problem. I feel that this is a legitimate safety issue that needs investigating as I see multiple similar complaints on your website and other internet sites.

- Suwanee, GA, USA

The contact owns a 2017 Hyundai Tucson. The contact stated that the vehicle stalled several times, the transmission gears were difficult to change over, and the vehicle was slow to accelerate. The contact had to coast the vehicle over to the side of the road. The dealer (lake norman Hyundai, 20520 chartwell center dr, cornelius, nc 28031, (704) 274-3145) indicated that the same oem transmission needed to be replaced. The dealer kept the vehicle since May 9, 2019. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was not available.

Hesitation and stalling from the dual clutch transmission. It is a safety issue with my family in the car and surrounding areas on the streets and highway and also parking lots. I have been back to my dealer twice and was told there is nothing they can do. I feel mostly unsafe when this hesitation happens on a busy highway. Hyundai on my second visit only used the computer to turn off the check engine light but the problem was very much the same. I need help please

- Newton, MA, USA

The vehicle hesitates before accelating after the car is stopped at a traffic light. Basically the car does not move at all. Seems "dead." As a driver, I put my foot on the gas pedal and nothing happened. After about 30 seconds, the car kicks in and will move after awkardly lurching forward which is not particularly comfortable or safe for the driver and passengers. This has happened multiple times. The dealer blames it on the dual clutch transmission and advises that it cannot be fixed. I am concerned that this could lead to another driver rear ending my vehicle or another type of accident.

There is a hesitation when the car starts out in the morning, first start of the day. I have had a new transmission put in, but after a few weeks the problem returned. It causes a safety problem when I try to pull out into traffic, because it feel like it is going to stall out and them it catches and moves.

- Lanoka Harbor, NJ, USA

Everytime I stop at a light or slow down I almost get in a accident because the transmission keeps feeling like it wont shift and stall out and has no power. This is a known problem I need a resolution for please. I have kids and got this SUV for safety but now I am scared to drive with them

From a stationary position, when you apply the gas, the car may lurch and jerk like the clutch isn't fully engaging and then not move at all until the ignition is turned off and back on again. This can occur in reverse as well. Sometimes, when sitting on an incline, in gear and maybe waiting for traffic to clear, the car will roll back while moving my foot from the brake to the accelerator. This car has an automatic transmission. This has happened on city streets and the last occurrence was outright dangerous.

2017 Hyundai Tucson. Consumer writes in regards to loss of vehicle power which resulted in an accident.

- Howell, NJ, USA

When I make a turn right or left, joining traffic, I press acceleration and the car does nothing... I may even push the pedal to the floor, engine roars at 5-6K and the car does not move at all or moves extremely slowly... I watch the cards approaching from the back and start to pray... I barely escaped few accident situations because the approaching drivers were cautious enough about something wrong going on with my car, not moving. This happened multiple times. The authorized Hyundai service did not find anything wrong. But, according to other public records, the issue seems likely to be the dual clutch transmission (dct), later renamed to "automated manual", which is what I have in my Tucson.

- Midland, MI, USA

When you accelerate the vehicle the engine revs up to 5K to 6K and the car appears to being neutral. This occurs every tim I try to accelerate. The vehicle does not accelerate. Very dangerous when I try to accelerate to change lanes. The vehicle does no accelerate.

The contact owns a 2017 Hyundai Tucson. The contact stated that the transmission slipped and the vehicle jerked violently sometimes. On one occasion, in a shopping plaza parking lot, the vehicle jerked violently, the steering wheel seized, and the vehicle accelerated on its own. The brakes failed to operate and the contact's vehicle crashed into a parked vehicle twice. The air bags did not deploy. The contact sustained injuries to the neck and back, which required medical assistance. A police report was filed. The vehicle was towed by the police to an independent mechanic. The vehicle was then taken to an insurance body shop to be diagnosed, but a failure could not be located. The body damage was repaired. The failure mileage was 2,000.

- Howel, NJ, USA

The contact owns a 2017 Hyundai Tucson. The contact stated that the seven speed dual clutch assembly pertaining to the transmission failed to operate properly. As a result, the vehicle did not gain speed when attempting to accelerate from a light. Downey Hyundai (7550 Firestone blvd, downey, ca 90241, (562) 314-4331) was unable to determine the cause of the failure and provided a loaner vehicle. The vehicle was unable to be driven and was still with the dealer. The manufacturer was notified and had not issued any transmission recalls. The VIN and failure mileage were not available. Consumer stated transmission doesn't work when getting on freeway.

Something is majorly wrong with how this vehicle shifts gears. When you slow down, or don't come to a complete stop for several seconds, the transmission doesn't down shift properly, causing a transmission slippage and an over revving of the engine, which results in a delay in acceleration. This is an extremely dangerous situation when trying to merge into oncoming traffic. On several occasions, I have tried to turn onto a street or highway and nearly been rear ended or T-boned because of my vehicle stalling for no reason, leaving me floundering in the middle of the street until the vehicle decided to shift properly and resume acceleration. This vehicle needs to be recalled immediately before someone gets killed, for it is only a matter of time before that happens, provided it hasn't already occurred. In fact, I got in a car accident the other day while merging onto a frontage road next to an interstate, and I believe that this stalling transmission slippage is to blame. Please take this issue seriously as it appears that many other people are having this same dangerous problem with their 2017 tuscons as well. This dangerous defect occurs every day I drive this vehicle. Every day.

Takara recall. My vehicle was parked I started the engine. I noticed on the dashboard it said battery low and my car started to go in reverse slowly even though I had my car still in park and my foot on the brake. I turned my car on and off several times as it was slowly going in reverse and I change the gear from park to drive to move forward and it still went backwards. Finally the car came to a stop I turned off the car again and it started normally. This is why I'm writing to you today that my computer screen on my dashboard told me the battery was low and it did go in reverse even when the car was in park and my foot was on the break.

When you come to a slow stop, and then go to accelerate again, the car feels like it about to stall- then when you press on the gas, there is a long lag before the car gains any momentum to move again. I was almost in a major car accident at an intersection with my daughter in the car. The dealership keeps telling me it is a dual clutch, but this is way worse than a dual clutch. I was driving on a major interstate last week, int he middle lane in stop and go traffic, and the car almost stalled out on me in the middle lane, and then when I hit the gas, it accelerated and I almost slammed into the car in front of me. I have been driving for 30 years and this is the worst car I have ever driven. It is a death trap and Hyundai wont do anything to correct the issue. I dont want to drive my 12 year old daughter in it- but they wont help me. Today, my battery died in the car, so I had to get a tow truck to jump it and tow it to the dealership. It is only 2 1/2 years old!!! these models are unsafe!!

2017 Hyundai tuscon limited.....when accelerating from a stop the vehicle lags as though it is about to stall, sometimes with no acceleration when pushing on the gas peddle. Everytime I get my car serviced I have discussed this with the service department, they have had 3 different employees drive it & continue to try to explain it as the dual transmission. Recently entering on the freeway my vehicle jolted &died with no power I was able to coast to the side of the road barely making it out of the way of a truck that was speeding up behind me. The warning light illuminted the 'malfunction indicator light' this could potentially be a catalytic converter problem. Towed vehicle to dealership & they said it was a tcu software update. The next day drove less than a mile to car wash, turned car off & when I went to turn back on nothing no lights, no noise, nothing after about 15-20 min. Car started up. The vehicle is only 2 years old & I dont feel comfortable that it wont die out putting myself or passangers in danger or leaving me stranded. Hyundai service representatives no help at all.
