The transmission in my vehicle failed while driving and the car completely shut off while driving. Less than 4 months after replacing the transmission with a brand new transmission, the engine failed while driving on the highway. The engine started sputtering, then it started smoking, then the car stalled.

Greetings, I have had issues with the Hyundai Tucson 2017 I own for many months. Issues include among others an abnormal knocking noise from the engine, reduced engine power and/or hesitation, burning smell, oil leaking, and smoke coming out of the engine, misfires, and other issues. It happened many times on the highway and almost caused accidents and the last time it happened, the vehicle was towed, and recently the smoke coming from the engine forced me to pull over. I reported the issue to the dealer but they didn't recall or address the issue. The car has been maintained properly over time and now I fear for my life. It is totally unfair that about 100k of this brand have been recalled for the same issue, in my case it is just after I finished to pay in full the vehicle. I seek your support to have it addressed for safety

There is an intermittent problem with the transmission. It-??s impossible to predict when the transmission will slip. When navigating traffic, it has happened multiple times trying to pull out across oncoming traffic, and the transmission begins slipping so badly in a couple of instances nearly causing a side impact. There are no recalls related to this, but the dealership confirms it is common-?? the fact that it is intermittent makes it worse. You get used to the transmission performing as it should-?? Next thing you know it slips when you can-??t afford for it to slip..

I am writing to report a serious issue with my 2017 Hyundai Tucson SEL 2.0 that poses potential safety risks. The vehicle is consuming more than 4 quarts of oil every 1,000 miles, which is far beyond normal and acceptable levels. The car has approximately 166,000 miles on it and has been regularly maintained, including timely oil changes. Despite proper maintenance, this excessive oil consumption leads to frequent low-oil warnings, risking sudden engine failure if not continuously monitored. This creates an unsafe driving condition, particularly on highways or during long trips, as the engine could seize without warning. Additionally, I am aware that many other owners of Hyundai vehicles with similar engines have reported comparable issues. This suggests a widespread defect in the engine design or manufacturing process. I am requesting the NHTSA to investigate this matter further to determine if a recall, warranty extension, or other corrective action is necessary to address this issue. Hyundai should be held accountable for resolving this problem, especially since it compromises the safety and reliability of the vehicle. Vehicle Information: Year: 2017 Make: Hyundai Model: Tucson SEL Engine: 2.0L VIN: [Your Vehicle Identification Number here] Thank you for your attention to this matter. I hope for a prompt investigation and resolution to ensure the safety of all Hyundai Tucson owners.

The engine appears to have a malfunction, particularly related to acceleration and oil consumption. The vehicle is available for inspection upon request. The vehicle experiences sudden jerking during acceleration, which can lead to loss of control and increase the risk of a collision. Additionally, stalling can occur unexpectedly, posing a significant hazard, especially in traffic. Yes, the issue has been confirmed by a local dealership, where they noted the jerking during acceleration and the high oil consumption. Yes, the vehicle has been inspected by the dealership, but it has not been inspected by the manufacturer or insurance representatives. There were no warning lamps or messages prior to the incidents. The symptoms first appeared approximately 8 months ago and is ongoing.

Took my 2017 Hyundai Tucson 1.6t engine into the service center on 8/21 for a check engine light and Bluelink notification of "A possible condition with your Engine Control System has been detected" that came on Sunday 8/18. Service center diagnosed P0326 ($159) From the service center: We have pulled code P0326 for an issue with the knock sensor readings. The vehicle can sue an oil change as is due and there is a gasket leak which sounds like it is from turbo or manifold gasket which is causing that rattling noise you're hearing. Below is the three itemized recommendations for this vehicle. 1) Knock sensor replacement -$635 +taxes installed 2) Oil change recommended $ 85 +taxes 3) Turbo gasket replacement $205 + taxes installed. I bought my car in 2020 and only have 53,000miles on it and was told it's out of warranty so this isn't covered - even though the 2017 Tucson's are recalled/warranty for life for engine issues for the same exact reasons mine was brought in for. This is my second hyundai, which I have always loved; however, I am disappointed in the quality of car not being up to standard due to manufacturing, and I am paying the price for it. The10yr/100k mile and 5yr/60k mile warranty advertising is misleading and deceiving. If I could go back, I wouldn't have bought a hyundai

The problem began in mid to late April 2024 with the Tucson shuddering in the driveway while moving forward slowly. This vehicle has a 1.6L turbo with a dual clutch transmission. The mileage was around 96,000 miles. Once on the road, it ran fine. Approximately a month later the check engine light came on and it began hesitating upon acceleration. It would change to the next gear, accelerate and slam me against the seat! Whenever I try to accelerate too fast, it hesitates and loses power until it "catches" and starts speeding up. This is very dangerous especially when accelerating from a complete stop or after a turn. It also has trouble going up a hill and has actually died out 3 times while attempting to go uphill at a low speed. I am the second owner and it is out of warranty. I have contacted the local Hyundai dealer but their shop does not have a very good reputation and is always backed up for 3+ weeks. They also charge $230 or more to hook up their code reader!! I've already taken it to 2 other shops where that was done at no charge. The code was P073F - Unable to engage gear 1. Of course the only option I've been given is to replace the transmission for $3000 or have it rebuilt for $4100. This problem makes it very dangerous to continue driving it. I get the oil changed every 5000 miles. Of course it's almost paid for but I'm afraid if I try to trade it in I'll be lucky to even get enough to pay it off. I have been endlessly researching this online for recalls, updates or remedies. I want to know if replacing the entire transmission is the only option or is it a component of the transmission or a computer module that is the cause. How do I know the new transmission won't do the same thing?

The contact owns a 2017 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the vehicle was shaking abnormally with an unknown warning light illuminated. The contact stated that the failure occurred while driving uphill. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 94,500.

- Union City, CA, USA

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.

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.

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.
