The car would hesitate to accelerate causing the engine to rev high and then take off. It had gotten progressively worse with no error codes detected. With a lack of code, nothing could be done. My daughter was not comfortable driving the car due to the fact it had gotten so bad so I was driving her to school. While going 50 mph the engine started to rev high then completely died with no error or warning. I was able to coast off safely, however an inexperienced driver may not have been able to do the same. A recall needs to be issued ASAP before there are more serious consequences.

My engine began consuming oil at a faster rate. My miles per gallon decreased. Then while driving, my engine lost power, and then the check engine light came on without warning. Pulled into the closet mechanic (less than 2 miles) and mechanic found that I had lost all compression in cylinder 3 of my engine and that there was a large carbon build up. My engine just failed. I bring my Tucson in every 5000 miles for service.

Appears to be an issue with the Dual Clutch Transmission. Makes the suv jolt after starting, waiting in traffic/red light and/or randomly driving around. Speed is not a determine factor in causing this -??jolt-??, for it happens at any rate of speed. Fear is the suv will randomly just stall and/or completely give out while driving, especially on the highway!

- North Bergen, NJ, USA

The DCT transmission shudders when first accelerating then smoothing out. it also at times will not accelerate at all for several seconds. This can be very dangerous while pulling out into traffic because it doesn't do it all the time.The dealer does know about the problem and has been confirmed. No warning lamps.

- Kent, WA, USA

Vehicle doesn't want to accelerate when it is suppose to. Press on the gas pedal and it goes to the floor and when it does decide to accelerate it erratic. VERY scary and unsafe. Has almost gotten my daughter and I in an accident.

- Imperial, MO, USA

When I'm stopped at a light and go to push on the gas, the vehicle doesn't move, then all of a sudden it just takes off. Next the exterior driver side door handle doesn't open I have to pull on it a few times then it opens, there's like a delay. There are tones of complaints online about this, it's like the 2017 model's were just looked over when it came to SAFETY. My car only has 70K. Thank you.

Cracked cylinder wall in engine, after major oil consumption issues, complaints filed with dealership, corporate offices, did oil consumption tests and further hyundai corporate recommended an engine clean out which helped for a while however last year they had to replace my catalytic converter because it was "clogged", but still maintain that it didn't have to do with the oil consumption issue. No warning lights came on engine just wouldnt accelerate properly when pulling out in traffic, made noises and would not perform as it should. I have all service records pertaining to this vehicle since we have owned it. Dealership is wanting us to pay 8k for repairs because hyundai says its not covered under the recall.

- Topeka, KS, USA

As I was turning a corner the transmission seemed to disengaged; when I attempted to accelerate the car would not respond. It felt as though the car had shifted into neutral even though it is an automatic transmission and I had not made any adjustment. Very dangerous in I was in sn intersection and traffic behind and around me had no indication that my car had lost all power to move on its own accord. There could very likely have been collisions.

- Seattle, WA, USA

My concern is who is going to pay for the damage to my car? I initiated a claim with Hyundai due to my car malfunctioning at a stoplight, the light turned green and I gently pressed the accelerator and it lurched forward and smashed into the car in front of me. I had taken my car in multiple times telling them the accelerator sticks and hesitates. Each time they told me nothing was wrong with it. I researched online and I found many people were having this same issue with the accelerator in the 2017 Hyundai Tucson. I was also told there is a software update available to help with this. The service department at the Dealership said there is not one. I have an appointment with the Hyundai service department on 12/20, I need to know who is going to pay for my car.

This car has a the 7 speed DCT. This transmission is VERY unsafe. I have been fighting with the transmission losing power and being jerky for the last year or so. After looking online I found that EVERYONE with this transmission is having the issue. You never know when you will have power and it has almost got me into a major accident several times. There was a Class action lawsuit agains Hyundai in 2016 for the DCT transmission and they Hyundai lost. Yet they still put the same unsafe transmission in the 2017 and said they fixed it. Hyundai needs to be held accountable for lying to the consumer as well as putting the consumer in an unsafe situation.

Very often the transmission does not kick in when the accelerator is pushed and gas is applied. I.e when crossing an intersection, when passing, when moving forward from a complete stop, when changing lanes, and when on busy freeways. This has been reported to Dealer many times beginning in 2017. This has occurred when I have had passengers in vehicle as well as when other drivers have been behind the wheel. I again reported incidents in September of 2023 but could not get an appt with dealer scheduled until November 6, 2023. Since most recent report to dealer, I have experienced at least 4 more incidents that could very well have been life threatening.

When proceeding to move forward, the vehicle will sputter. Almost as if the vehicle is out of gas or not getting enough power to smoothly accelerate. This presents a very hazardous condition when leaving a red light or crossing an intersection. The vehicle jerks and sputters for about 2-4 seconds and then responds to the gas pedal and accelerates. Took it to the dealer and explained the problem and they said it's a known problem but there hasn't been a recommended fix and to drive the vehicle with the Turbo mode on. Even with Turbo mode on, the issue still persists.

Car hesitates when accelerating from a complete stop and the car will jerk when driving at low speeds while accelerating.

- Elkhart, IN, USA

Excess Oil Consumption, Gear slipping, Dual Clutch, Fly Wheel, Oil found in the Turbo inlet, Clutch dust found in the transmission, Encouraged to just keep adding oil and drive the vehicle. Encouraged to drive the car when there was assumed to have contaminated transmission fluid. Encouraged to keep extra oil in my car since it was consuming oil rapidly but was still considered with in specification from Hyundai. Encouraged to add oil and drive the car after it stalled and quit working. This is a known defect with Hyundai's. Some even catch fire and also stall at high speeds while being driven. This is irresponsible, hazardous, and neglectful behavior that could have hurt or even worse killed someone.

- Bothell, WA, USA

Excessive oil consumption, vehicle hesitate and sputters when attempting to enter into traffic. Spark plugs expire early. We've been dealing with this worsening issue for 40k miles. My wife no longer feels safe driving this car. Dealership could not recreate the problem. They likely know what the problem is.

- Las Vegas, NV, USA

I was driving the cars lights went off it started knocking then a scraping noise I looked under car the plastic cover was half off so I took off to see what the problem was 2 pieces of broken metal were on plastic cover and oil was coming out had to tow it took to dealership in Odessa where I bought to car still had packaging in it -?? dealership says my car is not one of the Tucson that has a recall on it-??why?

- Big Spring, TX, USA

There are no warning lights. My car stalls when I go to take off from a stop. It stalled on an interstate. It acts like there is no power if you put your foot on the gas all the way down It will take off eventually or if you put it in park turn it off and back on it will go without histation. This has happened at stop lights as well. I am scared that I will get hit.

The vehicle was serviced not long after I got it as a certified pre-owned vehicle for reprogramming of the transmission, which I told it was a just a reprogramming to make it more reactive. The vehicle would fail to accelerate, or have delayed acceleration. I was not aware at the time that these vehicles were known to have faulty transmissions and if I known this at purchase I would have spent my money on a more reliable vehicle. The vehicles transmission is having issues again, not reversing, not accelerating, etc. The Hyundai dealership I got it from told me that they won't even get me into the dealership for a diagnostic until January 6th, ,, which is a huge safety issue. Furthermore, apparently Hyundai is well away of the fact that they have allowed Hyundai owners to drive vehicles with faulty transmission and will not help with extended the warranty on their vehicles. I am 477 miles over 100,00. It seems as though they do not even want to help with repairs, even if they are out of pocket.
