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.

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.

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.

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.

When pressing on the accelerator pedal the Tucson jerks and hesitates and seems to almost turn of then after a few seconds will actually accelerate. This almost caused me to have an accident because it stalled when making a right turn.

Front axle shaft leak confirmed by aamco of East hartford technician

Driving into work on Friday June 2, 2023 my engine started making a noise that got progressively worse as I got to work. The engine was knocking loudly and I was not comfortable driving it home. I called AAA and had the vehicle towed to a Hyundai Dealership. The car has 77,780 on it. I bought it used in 2019. The engine is no good. No lights no indication of any problems just that horrible noise. I was told because I bought it used the powertrain warranty wouldn't apply. I did buy an extended warranty and am now waiting to see if they will cover the engine. I am now up to $300 in "diagnostic" fees. I knew the engine was gone I could have saved my money but of course need to now jump through hoops to see if this will be covered. Not holding my breath I am sure there will be some fine print in which is will be denied. They said that it would cost $15000 to put in a new engine. I owe $9000 on the car. UNBELIEVABLE!!!

I have had multiple instances where the car will not accelerate and can shutter or lurch when I press on the gas. I recently had an incident where I was turning left and the car lurched into traffic and almost stalled as I was trying to turn and avoid the oncoming traffic. This has happened before and is very unsafe. Fortunately, the oncoming traffic was able to stop prior to hitting my car. This apparently is a known issue with this model and the manufacturer refuses to address the issue for this year. I am at the point where I either need them to fix it or I will have to get rid of it because it is very dangerous.

My 2017 Hyundai Tucson (91,000 miles) suddenly started having issues shifting into gear. We pulled into traffic and were unable to accelerate for several seconds which created a hazard for both passengers and oncoming vehicles. We took to automotive shop in Clarksville, IN. It was determined that vehicle would not shift into first, third, or fifth gear. The shop informed us this was a common defect with this Make and Model vehicle. We were also informed that only Hyundai Dealerships could service because of specific software and calibration requirements for this specific transmission.

My Hyundai Tucson beginning at 65,000 miles Began consuming more oil than normal. There was a transfer of title through a family member with the vehicle and was not aware that in that case the cars 100,000 mile warranty is no longer valid. It is then reduced to half that or 60,000, one of the 2. I brought the fact up to the service rep at Hyundai that it was going through a lot of oil and they stated that it was normal with multiple cars that Hyundai produced. The oil was burning off and no detection of leak and no check engine light has ever came on. It never over heated. I then brought this up to Hyundai at about 92,000 miles and thats when I learned about the warranty being voided because of the transfer. The car at the time is running just fine but still burning oil and still nothing from the dealership about any issues because the check engine light never came on. Until I was going home one day and the car began to stutter and losing power. It was struggling to produce power and I finally pulled over to a safe spot. It did not wanna start after that. I had it towed to Hyundai service center and they later told me that my engine needed a fuel system flush. They did that and I drove it just fine for about a month. Then it did the same thing only this time the check engine light finally came on. The code was giving them a misfire of 2 cylinders and was not holding enough pressure. They then said my motor was gonna need to be replaced and that threw me off. I feel like that should have been detected much earlier but without any sign of overheating or engine alarms it just kept running up until that point of the motor no longer running. I feel that if I were to get some kind of check engine light earlier in then it is possibly that this could have been avoided. I feel like this issue remains and is well overlooked to many of their vehicles. I just need a new engine not looking for money or anything else, just a car that is reliable and safe.

March 6, 2023 the check engine came on and I came out of pocket $900 for new Ignition coils.. A month later, the engine starts knocking and now they're saying that the engine is completely bad and would have to replace it. The engine burned alot of oil in that time. I was getting oil changes before the oil change mileage mark. I'm stuck at this moment because there is no recall for the engine for my vin.

I believe the transmission is to blame as many others have stated. Our Tucson, without notice, quickly accelerates which is sometimes a scary situation. This defect can easily cause an accident. It happens often. It also sometimes lags when pushing on the gas and then accelerates as if I was in "sport" mode, when in fact I'm not. Hyundai has told me that there's nothing wrong with the vehicle so they won't look at it. That's obviously false as everyone knows now it's defective. No lights or warning devices activated.

- Boise, ID, USA

The car has been having numerous acceleration issues, it can take upwards of 30secs to actually start moving from a light or stop sign. It also seems to be shifting late and/or slipping. This had caused me to be stuck at a light in the middle of the road and almost hit by another car. Also, my engine completely failed within 5mins, I was driving and the check engine light came on, then the oil light, then the engine started smoking, and then the car died in the middle of the road. The engine completely seized in 5mins. I had all oil changes done and there was never an oil light on saying it was low. When the dealer checked the engine there was no oil, probably from the rod breaking out. There. Was some if the same issues with the same year that got recalled and fixed for free. I got quoted $16,000 from the dealer. That's more than I owe and what the car is worth. I'm stuck with no vehicle and don't know what to do.

I am the sole owner of a 2017 Hyundai Tucson Limited, (AWD) with the 1.6L engine, 7 dual clutch transmission, with 46,000 miles as of today Thursday, February 23, 2023. Currently, I am experiencing problems with the engine/transmission stuttering and vibrating, the gears slipping, and with the inability to accelerate when merging into oncoming traffic. In addition, what frightens me the most is when I am applying the gas when driving and the gears stick causing a brief halt in forward motion then, suddenly progressing forward with a quick burst of speed. On many occasions, I have shared my concerns with the dealership from whom I purchased my vehicle from Hyundai of Chantilly, located at 14848 Stonecroft Centre Court, Chantilly, VA 20151. I have been told that the dual clutch transmissions are trash in so many words and I have been quoted a price of $2000 to have the transmission replaced. I am at my wit's end and unsure of my rights and to whom should be held accountable. Therefore, I am writing NHTSA for assistance.

Powertrain: Vehicle losses power especially going up inclines or hills. This happened before and I spent over 4500 dollars on repair of a catalytic convertor that failed. This was Late may of 2022. Now the car is back at a Hyundai dealership because the Catalytic Convertor has failed again it is Feb 2023. The car has extreme oil consumption which is one of the causes of catalytic convertor failures. The car in November of 2022 had a loss of power again but this time coils failed. Had all three coils and spark plugs replaced. The certified mechanic shop gave me the spark plugs and it was if they had a black felt on the tip of them. The mechanic said this was a sign of high oil consumption. High oil consumption is also a cause of coils and spark plugs failing prematurely. I have records to show how much oil I have bought and it is about 3 quarts every 1-2 months depending on how much I drive. This is extremely high and a sign of a faulty engine. It puts me in danger of being rear ended in traffic or on an open highway because it losses power. I use my car for work and sometimes that work takes me to small country towns. My work sometimes mean I get back when it is dark or get up when to get to work when it is dark. A car failure on a dark country road is unsafe. Yes a Hyundai dealearship in Decatur and Lubbock TX as well as a certified mechanic in Keller Texas can attest to no warning lights or codes and the car has high oil consumption. Inspected by two different hyundai dealarship service repair locations NO warning lights, no check engine lights, nothing to give notice of a problem about to occur. I have tried to deal with Hyundai but they refuse to accept that the issues are due to a bad manufactured engine. However all the signs point to that is the problem. Lastly the check brake light comes on but mechanics can never find a problem. So they replace the bulb but it just keeps happening. It will come on, stay on for a day, then go off. Just periodic

On acceleration, the RPM's rev but transmission fails to respond. Slow to accelerate on lower speed end.
