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.

There is a problem with the transmission which doesn't allow us to accelerate fully. It usually happens when the truck is warmed up and very rarely happens when the truck is cold but the problem is that when you take off from a stoplight it does not accelerate like it should it holds back. You normally press down on the gas pedal to go and it just does not want to go and then it finally Clicks in and the truck goes but then it goes right back to not accelerating. If I had to pass cars I don't have the power to do that or if I'm on the highway switching lanes it struggles to keep up speed and climbing Hills on the highway it does not want to go and at times the RPMs go a lot higher than they should when Switching gears! I did read that the prior years to my Tucson did have a transmission recall but the 2017 does not.

My 2017 Hyundai Tucson refuses to accelerate after a complete stop at a traffic light, or just refuses to change gears after making a turn, or simply just lose power although on cruise control while drive on the freeway. I have reported the issue several times to Hyundai and the dealership, it seems that nothing can't be done and Hyundai is not taking my concerns seriously. I am not afraid to drive the car since I have a long commute to work, I escape several accidents before because the other drivers were cautious and kind enough when they notice that my car couldn't accelerate. Drivers have blown the horn at me on the highway because the car refuses to accelerate or change gear while I am driving. I can press the gas pedal all the way down, still nothing. When I press the gas pedal down, the engine start shaking and making a weird noise while the car still not accelerating or changing gears. I also notice that I am burning more fuel than expected, and I always get below the average for typical MPG. I personally consider this car is unsafe to drive, and I am strongly thinking about trade it in.

Vehicle throttle body sticks and causes hesitation when accelerating from a stationary position. This is a serious safety concern when turning in front of on coming traffic or cross at an intersection. This make, model, year vehicle has been recalled for this issue, but not every vehicle manufactured during the year -??2017-?? was recalled, as my vehicle does not show up as a recall.

- Westminster , MD, USA

1. lost of power/acceleration when in drive mode, has happen multiple times but told by service dept, nothing is wrong during their test drives. 2. driver door does not open on the outside, has to open from the inside. 3. smell of exhaust inside cabinet. Have been turned away from dealer services due to warranty coverage. I believe vehicle is a lemon

Three times in two months I stop at red light or stop sign take off and my Tucson would stalled in the middle of the road and would not go after padding the gas peddle three to four times the car would go then I am worried that another car will run in to me or hit me and some one will get hurt if not killed

I have done a significant amount of research and found that the Hyundai Tucson has three potential problems that cause the issues with the stalling/low power on takeoff. I believe that part of it might be the transmission not engaging properly in 1st gear and that should be something they can fix with a computer update. The second from what I've read is that the fuel tank has a material flaking off on the inside of the fuel tank causing the fuel filter to be damaged/clogged. The third and from what I have read, the reason some of the Tucsons fail is a bad crank shaft. My guess is that the bad crank shaft happens over time and that the problems start with the fuel clogs. The fuel system needs to be examined to ensure that the "flaking off" material defect inside the tank is not the cause of the fuel filter being clogged and eventually the car fails. The loss of power is scary and dangerous and must be resolved. Wouldn't it be cheaper if Hyundai replaced all the fuel tanks on the cars with one that doesn't have a defective material coated on the inside of them rather than replace motors and keep doing work on them over and over and over?

When on any hill (reversing or forward), in heavy bumper to bumper traffic, and in some intermittent situations, the vehicle experiences a loss of power. The scariest part of this is that the car jolts quickly once it finally "finds a gear" and decides to go. When my car dies because it can't deal with slower bumper to bumper traffic, there's a problem! when I'm trying to backup on a hill and there's an object behind me and I nearly hit it because I can't get the car to go, it's a problem. It's a manufacturers problem that you and they keep ignoring! just like the fires that they ignored for years. The dealerships report to hundreds of customers that this is normal. It is not normal. From what I have found in my research, it's caused by a couple of things. The fuel filter is constantly dirty from whatever fuel tank coating Hyundai used on the inside of the fuel tank that is flaking off. The second reason is a problem with the dct. It should be engaging the 1st gear and it's not. It should be something as simple as an update with the computer systems but Hyundai doesn't care about keeping their customers safe. It's ridiculous that hundreds and thousands of people complain about these issues and nothing is done. Not an investigation until they get enough and someone pays a lawyer to do it.because this happens all the time, I am putting the estimated date of purchase like other customers have done on here.

Bought the car new in February 2017. As others have noted, when I apply the gas, the car hesitates and then surges. Very dangerous at intersections where you have to get up to speed among other cars. Backing up on a hill is very difficult - nothing happens until it suddenly jumps. Holding and inching forward on a hill is similarly a challenge. The dealer of course says there's nothing wrong. The third time I complained they finally said it was a design issue and there's nothing that can be done. Other than that, the car is quite well designed. I really like everything else. But Hyundai really screwed this up and I don't want to drive such an unsafe car. I will probably sell it at a loss and I doubt I'll ever buy another Hyundai. Very poor. This form requires me to put a date that the incident happened. It happens all the time, so I just entered the day I bought the [xxx] thing.

The contact owns a 2017 Hyundai Tucson. The contact stated that while attempting to accelerate after a stop, the vehicle stalled without warning. Due to the failure, the contact had the vehicle towed to mccarthy olathe Hyundai (681 N rawhide, olathe, ks 66061) where the vehicle was diagnosed with a loose drain plug. Due to the damage caused by the loose drain plug, the contact was informed that the engine needed to be replaced. The contact then notified the manufacturer of the failure. After an extensive investigation, the manufacturer deemed the failure to have been caused by the negligence of the independent mechanic who serviced the vehicle for oil changes. The manufacturer denied to honor the warranty. The vehicle had not been repaired. The failure mileage was 47,110.

When accelerating from a stop or slow motion, the car sounds like it is accelerating but it does not move. You feel like you are in neutral. I had pulled out from a stop sign, with plenty of time to make the right turn, as traffic was back a distance. I pulled out onto the main street and did not continue moving although I was pressing on the accelerator, but the car RPM's were going up, no speed from my vehicle. By the time I let off the accelerator and let the car RPM's recover, the motorcycle was coming right up behind me. He was assuming I would be moving, but he had to swerve to miss hitting my car. This is very dangerous and it is very unpredictable. Both my grown kids have driven the car and have experienced the same thing. I have been to a dealership 3 times regarding this and they just stated it is the dct.

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.

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.

My Hyundai Tucson has almost 30,000 miles on it. About two weeks ago we began having an issue with delayed acceleration. We were driving normally through town and stopped at a stop light. When the light turned green I pressed the gas pedal and nothing happened. I pressed the pedal all the way down and still nothing happened. The engine did not rev or anything, suddenly after 3-5 seconds the car lurched forward and began accelerating. This happened dozens of times.I took the car in to the dealership as soon as I could. After a day with the vehicle the dealership said that there was nothing wrong. After getting the car back and driving it for about 30 minutes the issue returned. I again took it to the dealership. The service manager kept the car for 3 days and drove it about 80 miles over those three days and said the problem never happened while he was driving it. The failure to accelerate happens sporadically. Some days it will drive fine and other days it will have the issue the whole time I'm driving it. We have also had a few instances of the vehicle shifting incorrectly and over revving while driving on the highway. The acceleration issue is very dangerous and already almost caused me to get T-boned multiple times. It's not safe for my family.

July 2018 car began making noise when turning on and backing up. The noise went away when I began to drive. Took to dealership for oil change and they couldn't diagnosis the problem. Problem began getting worse, mentioned it at next oil change. Now mind you, I drive a lot!! car is 2 years old and has 83K. Between July and December 2018 the car received minimum of 4 oil changes all done at the same dealership who says it's normal even when I complained of smelling gas. After returning to va from mi, the lights on the dash all turned on while driving, speedometer jumped where ever it wanted if it wanted to move at all. Took to nearest dealership, diagnosis was bad vacuum pump. It was replaced and said all my driving issues and gas smell would stop. Nope....took back in, diagnosis is faulty exhaust manifold. Replaced. Two weeks later it starts to act up again like it did the first time.

***engine taking too long to start - smart key*** in some cases it takes too long the engine to start. Engine starter is working but is like the injectors are not supplying gasoline to the engine. It could be over 7 to 10 seconds starting the engine until the engine is running. After that I opened the hood and I found some oil stains on the valve cover. Also where the PCV ventilation is it looks like there is some oil vapors coming outside. Engine is the 2.0 gdi (nu engine)

1-al arrancar el vehiculo de manera ocacional SE queda ahogado no, no inicia Y si lo hace no alcanza la marcha apropiada, como si pasara un exceso de combustible O como si este no SE estuviera inyectando. 2-) al arrancar en trafico congestionado donde SE producen arranques Y frenados Y viceversa el carro lo hace con bastante dificultad, golpeando fuerte parecido a transmision, son golpeteos de arranque Y retroceso a la vez, creando la sensacion de un vehiculo que no va a avanzar.siempre lo hace en movimiento despues de estar caliente mas de 30 -60 minutos en marcha.

Dual clutch transmission (dct) / 1.6T engine start from stop acceleration stuttering, stalling occurs from initial take offs, while idling in stop/go traffic creates potentially dangerous drive/passenger situation in traffic especially when crossing traffic patterns and lane merging/passing. Issue has been brought to the attention of Hyundai corporate and two local Hyundai dealerships. Both parties indicate lack of knowledge on how to properly drive dct transmission and provided both video and written training packages. Both training mechanisms failed to resolve the issue. Supposed software updates by the leasing dealership failed to resolve the issue also. Issue is still active and latest visit to dealership failed to find any issues with no repairs or software updates taking place. Senior technician indicated Hyundai leadership at corporate are acutely aware of issue but choosing to not act accordingly/appropriately.

I'm writing this in regard to the issue I am having with our Tucson we bought new about 2 years ago. From early on it seemed the transmission loses power/ chugs. Hyundai sent out a survey about a month after we bought the car and I stated my issues then. My wife has had it in the dealership to have this looked at numerous of times just to be told they reset the transmission, can't find the issue or Hyundai is aware of this issue and looking into it. But looking in to this online seems this has been going on for quite some time. This issue is a safety concern as it loses power/ chugs when turning left in to oncoming traffic or when passing someone. At this point seems Hyundai usa is giving us (and others according to online) the run around. I would like to get this issue resolved quickly.

Vehicle frequently, intermittently, stalls during take off from a stop. When accelerating from a stop sign or traffic light vehicle will simply roll as if it is freely rolling in neutral but is not receiving any power or acceleration from the engine for approximately 3 to 5 seconds before engine/drivetrain engauges and vehicle accelerates. This creates an extreme safety hazard when you have the vehicle in an intersection and accelerate to make a left turn in a gap in traffic and end stuck in the intersection or in front of an oncoming vehicle because the vehicle is only rolling and not accelerating. This issue has been reported to Hyundai usa corporate who has chosen not offer any remedy and has it stated to me this is a "characteristic of my vehicle.". Hyundai usa has continually referred me back to the dealership, who does not have a fix for this issue. Hyundai usa has even place the blame for this issue on the dealership. However the issue here is that Hyundai usa engineers have not admitted to having this problem or created a fix to this problem to roll out to the dealership to allow them to remedy this problem. This identical issue has been reported and issued as a recall in prior models of this vehicle, yet Hyundai refuses to do anything on this model
