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

The vehicle drove fine on Christmas Eve. Then Christmas Day while leaving from a visit the car was in then randomly shut off in the middle. Checked the inside. No issues. Made it home and tried to go back out, the car crunk up and after a few seconds cut off. Tried it again and it started knocking. Checked everything again. Tried to crank the car up after about 30 seconds the car got extremely loud and shut off again. A mechanic came to check the car and said it was the engine/motor. Then another mechanic at the shop mentioned that it appears to be similar to the issues in recall 209. Along with multiple other possibilities since Hyundai has been having issues with engines for years.

Engine check light came on on 1/4/24 took it to dealership they ran a quick check and they said it had multiple misfires. The car has a lot of carbon buildup and they recommend a 24 hour cleaning which will cost me over $700.00. The car stalls and starts shaking as I speed up. I don't feel that a care with less than 70,000 miles should have this problem. Mine also has now been using up the oil very quickly.

My engine began making a loud knocking sound. When I brought the car in, I was told the rod bearings were warped, that the sound I was hearing was a rod hitting the engine, and that the engine would need to be replaced immediately or it would "seize up" at any moment. No warning light came on. There is a recall out for this issue for the same make, model, and year, but I was told my VIN did not qualify under the recall. I opened a case with the national office to have my car included under the recall as it is the same issue with the same make, model, and year, and was denied. I had to spend several thousand dollars on a rental car and purchase a new vehicle. The issue with the Hyundai has still not been addressed or remedied. When I went back to the dealership for the paperwork for my records, I was told no paperwork was completed when they diagnosed the issue.

Chronic over consumption of oil. You could change the oil and a day later the oil is completely black and burnt. Roughly lost a .5-1quart of oil a week doing minimal commuting. Eventually the wear from oil consumption left us with a cylinder loss and in need of engine replacement. The vehicle only has 65k miles. Clearly this is a serious problem with these cars. There is an active recall for this problem but our VIN doesn’t list. This is also the problem with many others who I have seen across all forums quora, Reddit, etc. We are sold Lemons and then footed with the cost to replace when this problem is very much known. It’s wrong on every level.

I was driving the car home and the check engine light came on , the oil light came on and the battery light. The car shut off and I coasted off to the side of the road and proceeded to get the car towed home. I then called larson hyundai in olympia wa. The first service advisor I spoke with after I told her what happened told me the car had a recall that was open for the engine and to bring it in on Nov 15 The car sat for 2 months waiting for the appointment. I finally dropped the car off at the dealership on Nov. 15 and two weeks later I get a call from the service department saying that it won't be covered. This is completely unacceptable And the car needs to be fixed Also the service advisor who is currently working with the car is the rudest employee ever. Today 12/22 she called and informed they want 10,000 for the engine to be replaced I was shocked and paused for a second. All I hear is her saying in a snobby voice he hung up and she immediately hung up the phone. Please help me with this

I was driving down the road and my “check engine” light came on and started blinking. Immediately afterwards, I noticed that my car acted like it would not accelerate. When I came to a stoplight, it was very sluggish to accelerate. I was right near an O’Reilly’s so I pulled in and had them use the code checker. It showed a P1326 code and I was advised not to drive the vehicle. I had my car towed to the dealership. The dealership called me the next day and advised me that the engine would need to be replaced, but the cost would be covered by an extended warranty. However-they told me it would be 2 months before I would get the car back!! They are not offering a loaner car nor offering to pay for a rental car! There is less than 65000 miles on my car! This is an extreme hardship on me. I work 25 miles away and cannot afford a rental vehicle for 2 months!

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!

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 .

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.

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.

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.
