The dual clutch intermittently shakes and hesitates while accelerating from a stop. Also, sometimes it's sluggish while driving and feels like it might stall. This is dangerous because if I needed to speed up to avoid a crash, I'm afraid the car may hesitate and be involved in an accident. There are recalls for other Hyundais with the dual clutch transmission for this same problem. Available for inspection upon request. Didn't show this to my dealer. No warning lamps. The engine has always intermittently shook and hesitated when accelerating from a stop. The feeling that the vehicle is sluggish and that it may stall AFTER accelerating while stepping on the gas pedal started recently around 19,300 miles on the odometer. I also reported this issue to Hyundai.

The sunroof has issues closing. Barely is used and the sun shade will not close. Also the car rocks and stutters when accelerating. It stops after you get going. Dealership said this is normal.

- Lake Worth, FL, USA

Issues when trying to accelerate from a slow day pace or from a stop. Worse on really hot days and really cold days. It feels like the car is cutting out and/or hesitating. I have almost gotten hit several times due to this issue. The car is also idling very loud after start up. I have mentioned these issues the last 2 oil change appointments and nothing has been done or looked at. Stated I need to have the fuel emission system cleaned at 80k miles and that should help. That is my next step, but I have read a lot of the same complaints and wondering what has been done.

- Butler, IN, USA

when en route to a Dr. appointment I was hearing a consistent knocking noise coming from the engine bay, the fast the rpm's were the louder the knocking sound. Upon starting the vehicle to leave the Dr. office the knocking was becoming very concerning in volume, so I decided to take it to the dealership approx. less than 4 miles. By the time that i made it to the dealership and had them inspect the noise they stated that they didnt trust the vehicle leaving their lot. It has been under their inspection process ever since. I have been having issues with them honoring the warranty i got with the vehicle upon purchase and the refuse to acknowledge the issue with the known recall on over 83% of the total Hyundai Tucson's of that years production run. When in contact with their "middle man" as she called herself, Hyundai has stated that if the engine is in need of replacement that they will only cover up to 80% of the total repair cost ($9,9**.**) leaving myself with close to $2,000 to pay for a vehicle in warranty.

My vehicle is not accelerating properly because of the transmission is failing for no reason. Sometimes it revs up to 4k RPMs and the car is barely moving. This can cause an accident since I can-??t merge or change lanes quickly.

- Dallas, TX, USA

The transmission consistently slips, or does not engage. It sputters, jerks, or simply does not go when the accelerator is depressed. One incident was so bad that when it finally engaged, it threw me back against my seat then sputtered and moved ahead slowly, all while merging into traffic. Very dangerous!

The dual clutch transmission is faulty. It jerks, acts like its going to stall and does not accelerate properly. It almost caused an accident while driving through an intersection. The vehicle didn't accelerate moving through the green light and acted like it was going to stall. Very dangerous!

The 2017 Hyundai Tuscan dual clutch transmission is seizing and unable accurate above 40 -45 mph. It is also unable to engage into reverse. It will shift into reverse, however will not move even when one places their foot on the gas pedal. The Hyundai Tucson seized while driving and I was almost hit in traffic. The dealerships in the Austin area have not been helpful as the closest they state they could look at it is November or December 2022 for a diagnostic and they are not willing to honor the powertrain warranty. After doing some research it seems a commen issue among Tuscan owners and is very similar to the issue Hyundai had with recall # 149 as related to the 2016 model. The vehicle is hazardous and unsafe to drive. The vehicle is putting the safety of myself and others at risk. There was no warning what so ever until later in the day when the check engine light came on. It is available for inspection.

Transmission jerks and shakes intermittently while slowly moving forward, can shake very violently, for example, waiting in line or at a stop light with foot on brake/slow release.

- Ruskin , FL, USA

transmission stutters on light acceleration from a rolling stop or after slowing for a turn and then speeding up. It feels like it is jumping between gears. I can recreate it by slowing from 50 mph to 40 mph (you can feel it downshift at or near this speed) and gently accelerate back to 50 mph. The car 'bucks' until it gets fast enough to shift. I can put the car in "manual shift" (it is an automatic transmission) and this doesn't happen. That makes me feel it is a computer shift control issue.

An update on my previous complaint is attached. My vehicle has now been with the Hyundai dealership for two weeks with no resolution. They've provided little to no communication about the issues, or progress. Additionally, they have not provided me with a loaner vehicle, so I am without a mode of transportation for two weeks.

I purchased my 2017 Tucson in 2020. It was the first car I-??ve ever owned. I do not know much about cars but I noticed that there was some hesitation in acceleration and the engine was loud. Sometimes I would hear soft knocking on colder days but nothing extreme. I was told that the acceleration hesitation and the loud engine are due to the turbo. Then on 4/27/2022, without any warning, my engine stalled while I was at a traffic light. More importantly, I had ZERO warning lamps or messages. No engine warning or oil light was illuminated. My engine suddenly stalled. I don't drive my car very far. Use is relatively light. On average I drive about 10-20 miles per day. No one was hurt but what if this had happened on the highway? I would have definitely been rear-ended and hurt. My car passed inspection on 09/10/21. But earlier this year, on 22nd February 2022, I took it to the dealer for the engine recall (NHTSA Campaign Number: 21V727000). They assessed it and said it passed the tests but I have no way of knowing because the dealer would not share the full report. Additionally, the dealer did not address that the vehicle warning lamps and messages were not working when they noticed my oil was low. Hyundai has a long history of engine issues and recalls with regards to high oil consumption and connecting rod bearings inside the engine may wear prematurely. There are hundreds of complaints that match my description. Their engines have had issues since 2020 and these complaints date back to 2020 around the time I bought this vehicle. Even though there were no recalls at the time, the dealer should have disclosed these issues. I think it's negligence by Hyundai and the dealer for investigating why my warning lamps did not illuminate and did not properly communicate the seriousness of these issues.

TCM component failed. Cause engine light to come on. During driving I went into reverse and it immediately stopped and shut completely off. If I was on the highway I would be in a severe accident. Hyundai inspected it but won-??t give me the diagnosis or the issue with the car specifically. Initially when it happened no lights were on. It just shut down and wouldn-??t move. A couple days later check engine came on.

- Covina, CA, USA

The contact owns a 2017 Ford Focus. The contact stated that while driving in traffic, the contact shift gears and the clutch ceased to the floorboard. The contact depressed the brake pedal to stop the vehicle. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The vehicle was towed to an independent mechanic who informed the contact that the failure was due to the master cylinder and clutch slave cylinder. The contact was informed that the master cylinder and slave cylinder needed to be replaced. The manufacturer was notified of the failure but, no further assistance was provided. The approximate failure mileage was 25,500.

The vehicles transmission sputters and takes 2-4 seconds to accelerate. This consistently happens both from a dead stop and at low speeds. This transmission/ dual clutch lag has almost caused at least 3 accidents. On 2 separate occasions the car almost stalled while making a left turn at an intersection, causing a near missed T-bone accident. The 3rd close call was almost being rear ended and not being able to accelerate away. Luckily, no accident had occurred yet but this transmission issue is without question a safety risk. I have brought the car to the Hyundai service department and have been told that this is common with the dual clutch system and nothing is wrong with the car. I'm sure this is not the first complaint as I have found a plethora if online forums on this particular issue with my exact year and make vehicle. This issue has and will continue to cause accidents until resolved.

The transmission slipped when I try to change lines from the right to the left to turn left into a parking lot. I slow down to look if no one was coming, and whennI try to accelerate the transmission slipped the car behind me speed up to pass me thats when I lost power and my vehicle stop and they hit my car. This transmission issues is been happening, and the dealership keep saying is normal now I dont have warranty and I contact hyundai USA motors and they denied to check the vehicle because the shop repaired the damages. This vehicle feels unsafe and they dont want to take responsibility we dont have other car so we have to keep using it. Even the dealer show no interest in taking it as trade in.
