What 983 owners told NHTSA about the 2017 Hyundai Tucson Fuel Cell

My engine began to leak and burned oil to a point where it needed oil changes much frequently than normal. Within 2 months of being made aware of the leak, I began to hear knocking noises. Once I return again to the dealership I was made aware now I needed a new engine. How is it that I've had my vehicle serviced only at a Hyundai Motor dealership and once my warranty is out, I now need an engine? What makes matters worse, there is a current recall on my vehicle year and make for the engine but I was told that my engine doesn't fall under this recall. I beg to differ! I am frustrated that I have yet another Hyundai that has failed me and I am stuck without a vehicle.

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!

NHTSA ODI 11559312

A knocking noise from the engine that increases in frequency as the engine rpm increases. Reduced power and/or hesitation and vibration. Illumination of the “check engine” light in the instrument cluster. Illumination of the “engine oil pressure” warning lamp.

Body - exterior. Door handles stop working and cannot open the doors. Engine - massive oil consumption issue. Having to put in roughly 10 QUARTS of oil in between oil changes, but low oil warning light inside of the cluster also never comes on to let you know if the oil is low.

Hyundai completed the recall in their system after inspection when the recall was not addressed. Months later I am experiencing check engine light and same symptoms from recall, and hyundai is booked out two months and telling me that the recall does not exist. Code reads severely damaged rod bearings.

NHTSA ODI 11558401

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.

NHTSA ODI 11557555

Without any notice the engine completely seized up and now I'm unable to even get a new engine because the engine is discontinued even though federal law mandates parts are to be available for 10 years.

The car does not accelerate from a stopped position and when driving it does not shift or allow acceleration. This is especially an issue on hills or when trying to increase speed on the highway.

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 .

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.

NHTSA ODI 11554246

Engine light came on and then went off twice so I checked the dipstick and there was no oil on it. So went to Express Oil Change and they ended up performing oil change- but there was none in it. Car could have stalled. Yes. I have to keep going to having oil added to keep the car running. There isn’t a leak anywhere, yet the oil level keeps dropping. I took to a Hyundai dealership and they told me they would perform oil consumption test but then called the next day (after I left my car there) and said they would not do it because I am the second owner. No. Yes. Engine light came on but when back off two times within the same hour which prompted me to check the oil.

Since I was notified of this recall on November 16, 2021, I have diligently followed the instructions provided, and my vehicle has been taken to a Hyundai service center for inspection and necessary repairs. However, I am deeply disappointed and concerned that despite the recall and subsequent corrective actions, my vehicle has continued to experience persistent issues related to the engine. I have experienced several engine problems, including repeated transmission replacements (twice) and dual-clutch replacements (three times), which have had a significant impact on the overall performance and safety of my vehicle. The frequency of these issues and the potential consequences, including engine stalling and increased risk of accidents, are alarming. I understand that Hyundai has taken measures to address the recall issue, but it appears that the corrective actions have not resolved the problem in my vehicle. Given the seriousness of the engine-related concerns outlined in the recall, I strongly believe that my vehicle's issues should be thoroughly investigated, and the necessary steps should be taken to ensure my safety and reliability.

THE CAR STARTED TO HAVE PROBLEMS WITH ACCELERATION DO NOT ACCELERATE MORE THAN 60 miles per hour and turned on the signal the engine and to get to 60 mph it goes slow little by little without strength since it only reaches 2000 rpm it does not go higher than there. In addition, all the lights on the blackboard came on, which means that I can't tell if there is something wrong with the car or not because everything is on. The proximity sensors don't work, and I get the code for engine is P1326 and the anti-Lock Brake System the computer show the code C1211-02, C1207-02, C1210-02, C1208-02 Y C1209-01.I took it to the Hyundai agency in Miami Lake where I bought it and where they told me that the car had 10 years or 100,000 miles of warranty and when I arrived the person who received me without passing the car to diagnosis or anything told me that repair costs you $700,00 and tells me that to my warranty covers the engine, the engine has to be completely damaged; I explained to her the engine was in bad shape that it was better to do the repair than to change an entire engine if it was still being used, but she was still in the same negative until she left. I need to make this report because I didn't have any help from the Hyundai that sold me the car and which is still under a factory warranty. I consider this a violation and abuse of consumer rights by deceiving the American people with a guarantee that they then do not want to fulfill

I had my engine replaced in match 2023 due to stalled vehicle. After several trips to hyundai. Now just 6 months later and as off present my check engine light is back on . I took my car in to get the immobilizer installed from another recall. The dealership is giving me run around. I am confused why if they replaced my engine with a new one why do I have the check engine on again just some time later. I keep all maintenance up on my vehicle. Additionally now my heat is not blowing hot it's blowing cool and consuming large sum of anti freeze. I have yet another appointment with dealership and have to leave my truck they don't have any loamers available so I have to figure out how to get to work and my son to school on my own all while paying car note for a vehicle I've really lost trust in. Unfortunately because of the thefts and recalls my truck is more debt than value at this point

Near miss accidents due to engine failing as a way KT of rapid oil consumption. Occurred twice causing near miss accidents at high speeds on expressway. Vehicle is currently undergoing oil consumption tests with dealer

The 2017 Hyundai Tucson is unsafe to drive. Purchased the vehicle with 62000 miles and have had issues with the vehicle since shortly after purchase. Vehicle consumes oil at a rapid pace - in between 3000 mile oil changes additional oil is needing to be added within 600 miles, while driving the vehicle on the freeway at 70 miles an hour vehicle stalls and goes into limp mode - huge safety issue. Vehicle has been at Hyundai three times now - first time Hyundai covered all of the diagnostics and repairs, mainly electrical for the engine. Second time vehicle was stalling again and diagnosis was catalytic converter needed to be replaced, caused due to manufacturing error that is causing oil consumption - Hyundai would not cover, out of pocket cost $3600. A month later vehicle stalled and was going into limp mode again, check engine light on and flashing. Took to Hyundai again, now the diagnosis is engine needs to be replaced. Hyundai is denying replacement coverage, these engine failures are due to many manufacturing errors on the engine, I have a case open with Hyundai however they are highly unresponsive, dishonest, and continue to deny coverage for an engine replacement due to me being the second vehicle owner - the vehicle only has 83000 miles on it at this time and should be considered as a warranty coverage due to manufacturing errors in this engine and the low mileage along with the regular maintenance always maintained on the vehicle. Hyundai is also being dishonest about costs for an engine replacement, I have asked for quotes multiple times and have been unable to get any assistance or answers from Hyundai. Hyundai and any dealership getting these vehicles as trade ins are selling unsafe and defective vehicles, these defective engines need to be covered by Hyundai to provide safe roadways for all.

Car engine needs to be replaced. As soon as it hit 100k miles the turbo super charge something is faulty or defected. Smoke comes out the back pipe, car always jerked but now it’s not accelerating at all. We kept up with maintenance care such as oil changes. Hyundai will not cover because it’s over the 100k warranty

Purchased the 2017 Hyundai Tucson used (2nd owner) with 62000 miles, before the vehicle was driven 10000 miles the vehicle stalled on the freeway, when it started back up wouldn’t go over 40 miles -took to the nearest dealership where they replaced the entire electrical mainframe for the engine, covered by Hyundai. Vehicle stalled again and check engine light came on around 81000 miles, took to the dealership again and they diagnosed as catalytic converter needed to be replaced - out of pocket expense. A month later check engine light on again, back at the Hyundai dealership and diagnosed as engine failure. Hyundai is trying not to cover the engine, currently have an active case with Hyundai due to engine manufacturing errors/problems and problems with oil consumption - we were supposed to start the oil consumption test right around when the engine failed too.
