Hello. I recently took my car to the authorized mechanic and had them check on an issue I am experiencing. For some reason, my car frequently hesitates when I go from a complete stop/slow roll to accelerate. For example, if I am stopped waiting to turn, often when I push the gas to accelerate, the car will begin to accelerate and then basically stop. When this has happened, I've pushed my foot down to the floor on the pedal before to make it go and it refused to go for about 20 or so seconds. Additionally, if I am in slow moving traffic and traffic begins to speed up, my car will hesitate to go forward when I try to accelerate. This is a huge safety concern. The mechanic was not able to replicate this issue, but it happens every day or every other day. It makes me scared to drive because it's almost caused accidents. I read I'm not the only one with this issue and honestly, it's a miracle no one has died yet as a result of this faulty issue.

When accelerating from a stop, the vehicle "chugs" or hesitated substantially before actually accelerating. There is usually a noticeable jerk at that point as well. Concern is this usually happens when turning and has caused safety issues related being stuck in an intersection until the transmission releases and allows the vehicle to accelerate. Several trips to the dealership have provided no repair/relief to the issue. We are always informed its a known issue with the double-clutch engine and just something we need to get used to. Most recently, the transmission is "slipping" when accelerated. This has happened at minimum 5 times in the past month.

When accelerating from a full stop or yield, vehicle takes up to 3 seconds to fully respond to pedal. Vehicle will move about 5ft forward during this 3 second lag time. After the lag time, the vehicle jerks into motion. Very dangerous to turn onto a busy road with 35mph speed limit.

2017 Hyundai tuscan will lose acceleration when driving down the highway or any street. Slow acceleration from complete stop. After pulling over shutting the vehicle off and restarting it will accelerate properly sometimes for minutes, sometimes for days. This has been happening since purchasing the vehicle about 7-8 months ago.

When coasting, the car idles rough and lurches forward. When stopped and pressing the gas, it takes sever seconds for the car to take off. This puts the driver at risk as it doesn't happen consistently- you can either take off right away or you're delayed. The rough idling sounds and feels as though the car is about to stall. In traffic, this presents a hazard.

To whom it may concern, according to Hyundai's 10 year/100,000 mile warranty, ''repair or replacement of powertrain components (I.e., selected engine and transmission/transaxle components), originally manufactured or installed by Hyundai that are defective in material or factory workmanship, under normal use and maintenance.' Currently, certain Hyundai vehicles with a dual clutch transmission have caused the vehicles to shudder and lurch, causing potentially dangerous situations for drivers and traffic. A civil action lawsuit has come out awarding anyone with these vehicles monetary compensation but has an unfair and pointless cutoff at a certain mileage that has nothing to do with the issue pertaining to the vehicles and still does not fix the problem of driver's safety as Hyundai refuses to fix the issue. Because the transmissions use computers, the issue is that there is not a code yet created to solve this issue. It is also not possible to switch the transmission out for one that does not lurch from other models as it will not fit into the cars correctly. Because of this defective transmission that threatens driver's safety, it could be viewed as violating product liability laws. This might be an issue worth investigating and the publicity could help drivers with these vehicles by putting pressure on the company to fix the issue instead of just paying them off for their silence.

On numerous occasions this vehicle has failed to accelerate. The vehicle rpms rise but it takes roughly 2-3 seconds to engage. I feel this is very unsafe especially when making a left turn in traffic. I have take it to the dealer more than once with no help. The 2016 model was recalled for exactly what I have experienced and I believe the 2017 model should be as well.

Car engine/transmission stalls, lags, hesitates, jumps and chugs when gas is pressed from a stopped position or in slow stop and go traffic. When pressing on the gas pedal the engine/trans does not engage and move the car. After a few seconds the car will engage and jerk, and jump. The hesitation makes the car feel like it is going to stall out. Very dangerous situation. I am afraid every time I get in the car to drive. This has been going since the day bought the car

From stop to 30 mph intermittent hesitation. Dangerous when trying to merge for don't know if car will move or not. It 'bucks' from start to acceleration intermittently. From low speed to try to accelerate doesn't always want to accelerate. Dual clutch seems to be the problem and maybe something else. Hyundai service did nothing to help with this problem, just 'live with it'. would they like their teenager driving such a car?? some times car lurches forward too instead of hesitation. Gas mileage terrible too. Not getting what they said, 18-20 mph, once in awhile 25 or 30.

When attempting to accelerate from being stopped at a light, stop sign, etc. The vehicle stalls for about 3-5 seconds before moving. When attempting to change lanes or merge onto the highway there is a delay. I've had the vehicle for 1.5 years (original owner). These issues started approximately 1 month ago.

I love everything about my Hyundai Tucson, however the transmission issues are horrible. When you take off from a complete stop, you have to feather the gas pedal to take off, otherwise the transmission will slip during take off. Driving in rush hour traffic (stop and go) makes the drive feel like I am driving a stick shift, meaning the transmission feels jerky. This is something that happens everyday and for me is a safety issue.

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.

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

We bought our Hyundai Tucson in September 2018 and within weeks, we started noticing problems with erratic acceleration and inconsistent response of gas pedal. We have gotten the car evaluated numerous times, but nothing was diagnosed to be causing this. The service department kept saying that there are some known problems with acceleration that Hyundai hasn't communicated a solution to the service department, therefore there is nothing they can do. Often times the RPM level skyrockets leaving the car without the ability to accelerate. Our 7-speed dct is having shifting problems, hesitation with acceleration, and near loss of power. The transmission particularly misbehaves during warmer temperatures and certain driving conditions. The transmission problems occur without warning, which is a safety hazard. And is a danger to everyone on the road. The service department claims that Hyundai has known about the transmission and control module problems but is not able to do anything about it. We would have never purchased the vehicles if we would have known about the alleged transmission problems. We have been in the middle of left turns on large city streets, almost getting hit, because nobody was anticipating the sudden non response of the gas pedal. This issue is happening very frequently during left turns, because you have to be quick. We hope that this problem is taken serious as it is extremely dangerous to be driving with this car.

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

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.

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.

While driving I have noticed that when I begin to accelerate after a complete stop my car jerks forward and doesn't catch. It's almost as if the vehicle stalls before moving forward, this happens when moving forward or reversing from a complete stop. I haven't been able to get a response to the issue from the dealership though I've let them know there is an issue multiple times over the past 3 months.
