Car stalls and hesitates at stops and acceleration.. lack of acceleration from stop or slowing down. Lack of power at crucial driving periods. Condition creates dangerous circumstances.

Human life threatening mechanical failure. My car, VIN # [xxx] has a major flaw. While driving, the engine shut down when stopped at the red light. This happened twice within a thirty minute span. I immediately took it to the dealership and of course nothing is wrong with it. Human life threatening mechanical failure. My car, VIN # [xxx] has a major flaw.

The contact owned a 2017 Hyundai Tucson. While driving 20-25 mph down a road preparing to merge, the vehicle stalled and continued to roll forward. The contact attempted to restart the vehicle but failed. The contact noticed white smoke and stopped the vehicle by engaging the emergency brake. The contact gathered some of her belongings as the smoke turned gray and got 20 feet away from the vehicle. There were flames noticed coming from under the hood. A bystander attempted to extinguish the fire with a fire extinguisher meanwhile the fire department arrived to the scene. The fire department extinguished the fire. The contact sustained post traumatic stress disorder due to the incident. A police report was filed. The contact also mentioned that her child would ride in the rear of the vehicle and the safety seat was destroyed during the fire. The child was not present at the time of the failure. The contact stated that the vehicle was repaired per NHTSA campaign number: 17V226000 (engine) by route 2 Hyundai dealer (743 North main street, leominster, MA 01453, (978) 534-9999) in may of 2019 due to the initial failure in January of 2019 where the engine blew up. The dealer replaced the engine, but the failure reoccurred which lead to the entire vehicle catching on fire most recent. The manufacturer was not notified of the failure. The vehicle was destroyed and towed away. The failure mileage was 118,000. The VIN was unknown.

Engine light on after six trips to the dealership to repair the same problem.

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

Multiple instances (39+ and counting since I bought it new in Jan '18) of lag in acceleration when at a low speed (occasionally after being stopped) & then needing to speed up. Many times I was waiting to turn left across an intersection in front of on-coming traffic where you typically inch forward & then need to accelerate quickly to make it across before the next car comes or when the light turns yellow & then red. Sometimes it was inching up behind another car waiting to merge w/traffic, or in stop-go traffic & then not having acceleration when needed. In all situations acceleration was needed & despite pressing down on the acceleration pedal (sometimes to the floor), nothing happens for anything from a half second to at least a couple of seconds. The lag when turning left is very dangerous - potentially even fatal - due to needing acceleration & speed to avoid being hit by other cars. Being hit from behind by another car is a potential danger when trying to speed up & having a second or more delay before the engine kicks in - the driver behind must be paying very close attention in case my car doesn't move when expected. In this case it'd obviously be the other driver's fault, but that's no comfort should I sustain injuries from a collision due to a known faulty dct component/software. Same for the times I pressed the pedal and nothing happens, so I press it to the floor and suddenly it engages a second or two late - that lurch is unexpected & dangerous in itself. I can't see any pattern to it as far as car temp, air temp, time driving, amount of gas in the tank, etc. The times I've spoken to the dealership/service people they always say it's the nature of the dct & that it's normal. There was a recall for 2016 Tucsons for the very same thing & a software update helped, but nothing has helped mine so far. It's up to date w/service & software updates.

Their is a very noticeable delay in acceleration of he vehicle after pressing the accelerator. Also, on several occasions pressing the accelerator results in the engine RPM's increasing but no acceleration of the vehicle. This has resulted in several "close calls" when merging into traffic or starting from a traffic signal. These issues occur when pressing the accelerator pedal to accelerate the vehicle from a stop or to increase speed when the vehicle is moving slowly. The issue has happened multiple times with the latest on 10/24/2019. At almost every scheduled service visit I tell the Hyundai service representative about the problem and am always told that it is simply a turbo lag. The issue is dangerous as you never know when it will occur.

Driving about 25 mph turning into a parking lot the vehicle jerked forward, then just stalled. I barely got it off the road and finally had bystanders help push me off. It was towed to local Hyundai dealer and after review, they stated something about debris melted and got into the engine, which destroyed the engine. Was under full warranty and now it's been 30 days I've been without my vehicle.

2017 Tucson base motor & base trans, not the dct. Vehicle will not respond to throttle(gas pedal) input. While rolling slowly from a dead stop car does not accelerate. You must floorboard the pedal several times to make engine respond. Occasionally same will happen when changing lanes at speed. Dealer notified on several occasions. Response was "typical of dct". car does not have dct. Extremely unsafe--accident waiting to happen. Note to NHTSA-- most of complaints concerning this vehicle are for same condition. When will you issue a recall"?? what are you waiting for? must dozens of people die before you do anything?"

When I am in a complete stop my engine/transmission feels like it wants to stall or misfire. When I take off it keeps jumping because it has no power. I almost get in a accident everytime I stop and take off again. I have taken it to universal Hyundai 2 separate times for the same issue and they told me nothing is wrong with it. It is suppose to do that. I drove 10 other SUV the same as mine and had no issue and had good power. This is a major safety issue and almost got into about 7 accidents with it because it feels like no power or vacuum or anything. Idk how to explain. If I slow down but not stop then push the gas to get speed again the car bounces like it is miss firing or transmission went bad

I leased a 2017 Tucson intending to buy at the end. Over the past year and a half, with about 29,000 miles on it, I have had six different occasions where I pull out onto my busy 50 mph road and the vehicle will not move. It's almost as if it had stalled or slipped into neutral, no matter how soft or hard you step on the gas. Each occasion my son and I have come within seconds of being hit by dump trucks, tractor trailers, or other roadway vehicles. The dealership service says it's the dual clutch system, but cannot find anything wrong, they've reset the parameters to factory settings, but it does not fix the problem. Not to mention the ac just went on it out of nowhere. I am 16 months out from the lease termination, and feel so unsafe driving this vehicle due to the fact I have come within seconds of getting rear ended by dump trucks, then having the car buck forward and red line. Handfuls of customers have complained about this vehicle, but nothing will be done to address this until a family or person winds up seriously injured or dead. Unfortunately, my husband and I are at a crossroads deciding if breaking the lease would be better than winding up in a coffin, either way it'll cost a significant amount of money on our end.

At approximately 6:10 pm on Wednesday 8/7/19, I was on an outlying road turning on a roundabout, I had slowed to approximately 15 mph to enter the roundabout and was accelerating to exit it, when my 2017 Hyundai tuscon spontaneously and without warning shut off. The car slowed and the screens went black. I was able to get to the shoulder before it stopped completely and turn my hazard lights on. I waited a few seconds and tried the car, it started right up. I turned around and went home (8 minute trip, along outlying roads) I am unsure which component caused the malfunction that caused my car to spontaneously shut off.

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 trying to turn off the Tucson (vehicle has push button start) to refill the gas tank, the engine didn't turn off. While the engine was on, it restarted again the engine, all the warning lights turned on in the dashboard and the engine started to vibrate violently with RPM's around 500 RPM. Some seconds later the engine RPM stabilized (normal idle). I pressed the push button again and the engine turned off successfully. Went to the dealer but they were unable to duplicate the issue. No changes were made to the car.

Vehicle's engine is intermittently making noises again after exhaust manifold was fixed and also intermittently releasing carbon monoxide into the cabin of the vehicle. I have a video of the carbon monoxide reading, but the system will not allow me to upload.

- Wyandotte, MI, USA

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.
