36 Power Train problem

Failure Date: 02/14/2023

Purchaseing the vehicle two months ago, the engine service light started blinking. Taking the vehicle to several shops including two Hyundai dealers, I was informed the vehicle had an off market catalytic converter. I asked the dealership several times if there was any issues with the vehicle and they stated there was not. The engine first came on two weeks after the purchase of the vehicle. It is not safe to drive. The warranty nor the dealership will cover or assist.

37 Power Train problem

Failure Date: 01/05/2023

When driving at night and low-beams are on, there is a black void (looks like a black bar horizontally across the headlight projected area on roadway). Black void is eye level with driver’s view of the roadway. With the black void present, driver is unable to see the roadway clearly at night, which inhibits the drivers visibility and ability to see road hazards or animals crossing the road. Low-beam and high-beam bulbs have been replaced and checked for any burn spots or malfunction in the bulb itself; with brand new bulbs installed professionally, the black void is still present. Hyundai repair stated it is a known issue that has yet to be addressed by Hyundai manufacturers. Issue has been present for 2-months now. While driving on interstate, went to pass a vehicle and while accelerating the vehicle would not increase in speed. The rpm needle jumped to 5-6 and a “whiny” noise was coming from engine area. Pressed harder on the accelerator so the car would speed up and with the pedal to the floor, the vehicle speed increased 1 mph in 5-sec intervals. Exited the interstate and was traveling on road with 60mph speed limit. Tried to accelerate again, and the vehicle would make the whiny noise and would not increase speed or shift. Let off of the accelerator and the rpm drops instantly to 2-3. Rpm’s need does not smoothly increase or decrease, but instead jumps or drops instantly. When accelerator is pressed or when trying to increase speed, the whiny noise comes from engine. The vehicle sounds and acts like it is not shifting. Took to dealership and they said there are no recalls on transmission, but will not fix my transmission. 10-year/100000 mile warranty is still active, as it is a 2018 w/ 89500 miles. Safety concern as the vehicle will not accelerate or shift when needed and could cause serious accident if in a situation where evasive action is required.

38 Power Train problem

Failure Date: 11/26/2022

Leaving a parking lot, vehicle was hard-shifting at 10mph, 20mph, 30mph and was not gaining typical acceleration. Every slow down or stop sign/stop light this behavior continued with automatic hard shifting between gears and lethargic acceleration to the point where I felt this may cause an accident or cause another vehicle to have an accident due to lag response of my vehicle. Upon home arrival, I attempted to back vehicle into my parking spot but after shifting into reverse, the r indicator on console was flashing but vehicle would not move. I drove back around the complex parking circle and again attempted to back vehicle in to a different parking space but experienced the same issue where r indicator was flashing but vehicle would not back up. My daughter and 2 grandsons then had to push my vehicle back in to the parking spot. I turned vehicle off, waited approximately 90 seconds and restarted the engine. When I shifted into reverse gear, the car abruptly and harshly shut down. At that point, I put the vehicle back into park gear and turned off ignition. Had the vehicle towed to closest dealership on Nov 28th - they have not been able to replicate issue nor find any fault codes when running diagnostics. No dashboard errors appeared, only the flashing reverse indicator light on shift console. No prior issues earlier in the day when using vehicle, nor has this issue occurred in the 4 years I have owned it. It was severe enough I wasn't sure the vehicle would clear intersections in a timely manner, and worried it may leave myself and my daughter and grandsons stranded on the 20 minute ride to home.

39 Power Train problem

Failure Date: 11/25/2022

Vehicle stalls when accelerating at low speeds. It appears to be a delay when the car transitions from 1st to 2nd gear. This creates a safety concern, especially when taking turns into traffic due to delays/stalls when turning.

40 Power Train problem

Failure Date: 11/01/2022

Transmission is jerking when driving. Brakes are squeaking.

41 Power Train problem

Failure Date: 10/21/2022

While driving my car normally 9 dashboard lights came on suddenly including the check engine, abs, brakes while at the same time the dials on the dashboard including the rpms, speedometer, oil temperature and more all stopped working. This happened suddenly while the car was in drive and also caused issues with the transmission as the car stopped shifting gears properly and was driving very rough. With this sudden onset of many different issues out of nowhere driving the vehicle was very dangerous when trying to get to a safe location. After parking this electrical issue would not allow me to take the car out of park or use a obd reader do to the electrical issue. After researching this problem I found several reports online describing nearly identical symptoms all of the sudden resulting in the car being undrivable and in a dangerous state. These owners said they took the cars to the dealer who tried replacing several components without fixing the issue with hours of diagnosis charges. Eventually after having the vehicles for several days they replaced the reverse camera which it turns out was shorting a significant amount of other critical car electrical components. With no prior damage to the camera or these electrical components the abrupt and random onset of this issue pose a significant safety risk to Hyundai Tucson drivers (at least in 2016 -2018 models) . My experience with the Hyundai dealership was very similar to them even after I had diagnosed the issue to the camera the dealer said they had contacted the manufacturing engineers who took several days to determine what was causing these electrical issues. This is not an isolated issue as multiple Hyundai Tucson owners have reported this to Hyundai and their dealerships yet they fail to recognize the risks associated with the faulty cameras they install in their factories. They need to recall their vehicles prone to having this issue. This has cost me $1000 to fix and put me at risk on the road.

42 Power Train problem

Failure Date: 10/13/2022

Acceleration issue, from a stop position on a red light or stop sign, when the gas pedal is pressed the engine revs but does not move immediately, after a couple of seconds it lundges forward, also when trying to merge you must wait for a very big gap to safely merge, the car does not respond and this is very dangerous, Hyundai need to rectify this issue before someone dies.

43 Power Train problem

Failure Date: 10/12/2022

I’ve been having an issue with the car “jerking rapidly” when in traffic and rolling slowly and when climbing relatively small hills, it began about 2 months ago but have become progressively worse over the last month. I was told by someone with a similar vehicle that it is the “lower arm control. Need help with is or if there is a recall.

44 Power Train problem

Failure Date: 05/01/2022

Powertrain issue. Multiple times the after stopping the engine revs for a few seconds and then the vehicle will lurch forward. It acts like the cvt transmission has a delayed response to the accelerator. The condition comes and goes and sometimes it happens multiple times in the same trip.

45 Power Train problem

Failure Date: 03/22/2022

Driving down the road, accelerated to speed limit, but the car slowed down and the rpm's stayed at 2000. The car just stopped running and I was able to pull over into the middle lane. Towed to dealership, 6 weeks min. To diagnose until we know what happened . Dangerous!!!.

46 Power Train problem

Failure Date: 12/17/2021

Rod bearing failure. Sounded like a tractor all of a sudden and stalled every time I’d come to a stop. Had it towed to the dealership. Awaiting word from Hyundai as to whether the warranty will cover this. Checked oil and wasn’t low. No check engine lights or oil lights or anything ever came on. No noises prior to this happening. Kept up on routine maintenance.

47 Power Train problem

Failure Date: 11/14/2021

Very bad acceleration from a stop position, engine revs but does not move, in slow traffic it hesitates and lunges forward like it’s not sure what it’s suppose to do, when trying to merge or pass another car, you have to give yourself time, it’s very dangerous, took it to the dealer 2 times, was told that’s how the car is made, there is no way this is suppose to be the way the car was built. Also a smell of antifreeze but no leaks detected,.

48 Power Train problem

Failure Date: 11/14/2021

Car has no power when accelerating, when accelerating from a stop the car revs but does not move, then when it does move it takes off like a rocket, in slow moving traffic 5 mph, you accelerate and the car seems like it wants to stall, a lot of hesitation, in fast moving traffic, if you want to merge or pass another vehicle you must give yourself ample time and make sure it is clear to make your move, if you need to get out of the way really fast you cant, its very dangerous and Hyundai needs to move quick on this before something really bad happens to someone.

49 Power Train problem

Powertrain issue. Multiple times the after stopping the engine revs for a few seconds and then the vehicle will lurch forward. It acts like the cvt transmission has a delayed response to the accelerator. The condition comes and goes and sometimes it happens multiple times in the same trip.

50 Power Train problem

Failure Date: 09/15/2021

My 2018 Hyundai tuscon has been having major issues with the dual clutch transmission, which has put myself, my family, and others in very dangerous situations. Everyday when I start my tuscon and accelerate, it stutters/jerks like it’s going to stall and will not accelerate/shift. It eventually starts going, but I have to pull out onto a street, which has been unsafe when cars are speeding up behind me. It does not go up hills well at all. I turned onto a road where there was a decent sized hill, but nothing major, and nothing an SUV should have a problem with. My previous car could drive it just fine. You’d think an SUV could as well. Nope. Very scary moment. My tuscon made it not even half way, and just stopped. I was pressing the gas, and it just revved it up with no motion. I braked and tried it again, and it still would not go. I had to roll backwards down the hill. This was the only way to my destination. I rolled down, and put it in sport mode to try that. It still would not go, and did the same thing. I tried again in regular mode, and it still would not go, only this time I had a car behind me. The car had to back down, and I rolled back a little bit, then hit the gas in drive and it eventually made it, but definitely very scary and unsafe, and it put others in danger as well. I was going to church one morning, and the speed limit on the main road is 60, which is what I was driving. I had to slow down to turn, and had to stop to oncoming traffic. I had to brake for maybe 10 seconds, and when I went to accelerate, it was like it wasn’t shifting, and it just revved up, rolled slightly, and would not go. At this point there are more cars coming. I am in the road right in their path due to it rolling, and once again I am put in a very scary situation. I kept trying, and it finally went. This was also on flat level ground. I have had many moments (every day) where it does not shift properly, and it also stutters every single day when I start it. Please fix this.

51 Power Train problem

Failure Date: 09/10/2021

Vehicle has judder at slow speeds or hesitation in shifting gears. Has almost stalled while making a left turn at intersection into oncoming traffic or accelerating after stop sign . Dealer updated tcu ecm software, problem got worse. Appears to be a dual clutch transmission defect.

52 Power Train problem

Failure Date: 09/01/2021

Hyundai has historically had an issue with the dual-clutch transmission and the vehicle is available for inspection upon request. The vehicle frequently shutters / shakes at a stop and when accelerating from a stop. Additionally, the vehicle occasionally loses power to the wheels when driving-up a moderately steep grade. Additionally, the vehicle has delayed acceleration when trying to increase speed from a constant speed. This has put my safety and the safety of others at risk by being unable to properly accelerate into a turn while driving at highway speed, by being unable to keep up with the speed of traffic while driving on the interstate in the mountains, by being unable to drive in adverse weather, and by not being able to account for the jolting of the vehicle in busy city traffic. I've taken it to two manufacturer dealerships who have ran a shutter test and could not generate an error message, but acknowledged the effects felt when driving the vehicle and the commonality of the problem. They said their hands are tied if the manufacturer's testing generates a pass result. There have not been any warning lamps or messages. To date, I have been unable to come to a resolution, but the vehicle is dangerous to drive.

53 Power Train problem

Failure Date: 08/13/2021

My 2018 Hyundai Tucson starting having lurching issues on when first started. I have to back into my driveway so I dont have to go in reverse then go forward. It jerks back and forth so hard. It finally took its toll on the transfer case and it exploded internally. The dealership said they had never seen this before. I was hoping that was the cause of the issue but it wasnt. Still doing it and am afraid it will do it again. I was under warranty when it happened, so teh $2000 replair was covered. I'm concerned it will happen again. Teh problem goes away after it's been completely warmed up. But like many others, its a scary issue when first started. It also will also shift hard when it firsts get's going (after the initial hard lurching back and forth). I dont know what to do. Love the car otherwise, but concerned with ever buying a Hyundai again.

54 Power Train problem

Failure Date: 08/12/2021

Car not shifting properly. Took to dealership and kept getting a response of the car have a dual clutch.

55 Power Train problem

Failure Date: 03/09/2021

Warning light on dashboard board goes on and off constantly indicating rear brake light needs attention. When warning light is on, brake light does not work. When warning light turns off, brake light works. This happens when car is on and constantly at random times even when I'm stationary. Also, when I'm stopped, car tugs like it wants to accelerate.

56 Power Train problem

Failure Date: 03/01/2021

The vehicle almost stalls and doesn't want to take off 1st thing in the morning then suddenly it accelerates abruptly well above the amount of pedal pushed. It also has inconsistent shifts at anytime during a drive. Sometimes it won't shift until we leave off the gas. This has been twice in for diagnosis at rom marhofer in cuyahoga falls, ohio 44221. Both times they tell us--they could not get the vehicle to produce the symptoms. It does this everyday of the week for us--everyday. The service writer says this is common for the dual clutch transmission. This is a safety issue with not having power to move then suddenly--wham.

57 Power Train problem

Failure Date: 02/01/2021

I was driving on a interstate got off on a exit and my car started doing a loud ticking noise and would not accelerate over 40 mph. I drove the car to get the car tested to see the problem . The code read knock sensor. Got the knock sensor replaced by a local mechanic and the car drove the say way before I took it to his shop. The car only has 67,00 miles.

58 Power Train problem

Failure Date: 01/15/2021

Car was slowly entering garage and came to a full stop with brake pedal depressed in gear. Car without warning, engine revved up to full power and crashed in garage. I am alleging condition known as sudden unintended acceleration. I have had the damage repaired and the cost of repair was over $4,000. 00. Pictures available upon request. Hyundai performed an inspection on vehicle upon my demand to do so. When report came in, I was refused a copy of exact report by inspector and only given a summary by company agent. When I asked for the exact inspector report to be read to me over the phone, that request was denied as well.

59 Power Train problem

Failure Date: 10/17/2020

Car constantly hesitates when starting to accelerate. When you begin to accelerate from a stop, the car hesitates for several seconds before beginning to move. This is very dangerous when making turns at stop lights or in intersections. Going at highway speed the car runs fine and accelerates without issue. The problem is when at slow speeds or at a stop and you need to accelerate. Also, when going slow or slowing down to a stop, the car sees like it is going to stall and the engine/transmission begins to jerk as if it is about to stall. When driving through a parking lot at slow speeds with some quick on/off breaking, the car hesitates and feels like it is going to stall.

60 Power Train problem

Failure Date: 09/22/2020

The transmission severely lags in the initial transition into first gear, as well as from first to second. When initially engaging into first gear from reverse, the car rumbles and chops into first gear. Although this is a dual clutch car, it severely lags into acceleration, causing a major safety hazard, especially on the freeway. We have taken the car to the dealer for repairs but they hide behind the excuse that this is a dual clutch transmission. The issue first occurred at around 500 miles. It has only gotten worse since.

61 Power Train problem

Failure Date: 09/05/2020

When the vehicle is at a complete stop it will have issues going when I push on the gas. It takes a few seconds to go and it will jerk forward and then go. It doesn't happen every time but it is often enough that it's worry some and could be unsafe.

62 Power Train problem

Failure Date: 08/05/2020

Has developed inttermintant shift stutter while driving (city and hightway) and dealyed power from a stop (no go syndrome). The problem isgetting worse and the Hyundai hasn't been able to fix it.

63 Power Train problem

Failure Date: 07/22/2020

Mostly in the morning after the vehicle has sat all night and occasionally throughout the day after stopping at red lights or when leaving a parking lot. The vehicle will �stall, shutter� or however else you want to describe a rapid jerking motion while trying to accelerate from a stop. It causes a delay in the ability to effectively and safely merge the vehicle into traffic at times.

64 Power Train problem

Failure Date: 07/22/2020

Vehicle caught fire while driving on the highway.

65 Power Train problem

Failure Date: 07/15/2020

Bought the vehicle new. The problem originally began as intermittent now occurring almost constantly. If vehicle is in a stopped position upon pressing the accelerator the vehicle does not move forward for up to one to 2 seconds. The rpm shows that the engine is revving but no motion. Then suddenly the vehicle will lurch forward. The amount of pressure applied to the accelerator does not make a difference in the vehicle response time. I am very concerned about the safety of this vehicle as the vehicle will not accelerate when necessary. I have brought in the vehicle for repairs of this problem twice and was told that Hyundai knows of the problem but because the issue is not extreme enough nothing can be done. I do not believe that the vehicle can be operated safely given the current defect.

66 Power Train problem

Failure Date: 07/11/2020

, from a stop, when you move forward, you press on the accelerator the car hesitates to move forward then all of the sudden if reves high and then speed faster than it should, I have called the dealership two times, the vehicle has 11,000 miles on it and has never been in an accident. Something with the dual-clutch system is having issues and will lead to death. The vehicle does it intermittently, so you can not predict it when it will have an issue, at min, it does this frequently.

67 Power Train problem

Failure Date: 11/08/2019

When I went to accelerate out of a business drive way, the car hesitated at least 1-3 seconds before engagng the transimission to acclerate the vehicle out of the driveway into traffic. As I was turning out of the driveway, I was almost struck by an oncoming vehicle. I was in 2 other separate incidents either accclerating to get into a lane or accelerating from a stopped position almost causing accidents because of this problem. I was so scared, I traded the 2017 tuscon in for a 2018 tuscon hoping the problem would be solved. It did not. It happens in the 2018 tuscon less often, but more intermittently making it even more dangerous as you do not know when or if its going to happen and be able to react appropriately.

68 Power Train problem

Failure Date: 10/01/2019

The contact owns a 2018 Hyundai Tucson. The contact stated while at a complete stop, the vehicle hesitated while depressing the accelerator pedal. There was no warning light illuminated. The contact called the manufacturer and the dealer and was informed that the VIN was not under recall. The vehicle was not repaired. The failure mileage was approximately 47,000.

69 Power Train problem

Failure Date: 09/10/2019

The dual clutch, 7 speed automatic transmission in my 2018 Hyundai Tucson does not always move the car. When pulling out of a driveway, intersection, or crossing oncoming traffic lanes the car will stop moving while partially in the street/intersection. It will not move, the engine rpm's rev up and then all of a sudden the car lunges forward. I am afraid that a car approaching me may not stop in time and run into me, even though I had plenty of time to make the turn. I took the car to the dealer on 9/24/2019 and they said they were �unable to duplicate the issue�. I returned the car to the dealer for the same issue on 5/5/20. The car was returned to me after 6 weeks and the dealer stated they replaced the transmission and dual clutch assembly with a new unit and I was informed that this may not resolve the original issue. On 6/24/20 the car was returned to the dealer for the same issue and the dealer was unable to duplicate the problem. At no point did Hyundai tell me they've had ongoing issues with their dual clutch transmission. It was my own research and contacting another dealer that I was told Hyundai is aware of the problem and has no current solution to resolve the matter.

70 Power Train problem

Failure Date: 09/05/2019

Starting at about 12000 miles, my car will at times fail to accelerate from. A stop. It happened again today and I had to jam the pedal down and my car revved to 7000rpm before it would actually accelerate. It kept doing this the whole rest of the time I was out and it was very dangerous since I was driving on a highway and couldn't get my car to accelerate. I took it to the dealership and they claimed there was no problem. This is very dangerous!.
