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

The vehicle started exhibiting symptoms of oil consumption in February 2022 and I had it into the dealer because I thought there was a leak but there was lack of power and the car seemed like it wanted to fail. After months of adding oil due to the excessive consumption, it just stalled and died in February 2023. I received an extended warranty for 150,000 miles on the engine and the dealer denied my claim and placed blame on me because there was sludge in the engine, lack of maintenance records even though I provided thorough maintenance records.

Engine was burning oil and depleted all of the oil before oil change was due. There were no warning lights to indicate low oil pressure and car stopped accelerating properly almost causing us to be hit when pulling out into traffic. Vehicle has continued to burn oil and has to be checked constantly and oil added or the problem will reoccur

Around 80K miles, the oil consumption really started to become an issue and I took it to a few repair shops and no one could figure out what the problem was even though the car was consuming oil faster than it should have been. It wasn’t leaking, it wasn’t burning off, it was just using oil somewhere in the car. I checked the oil weekly and topped off if needed. I was driving down the interstate when the car completely lost power and would not accelerate, putting me, my family, and other drivers in serious danger as the normal speed for the interstate is 70 mph and I was surrounded by other vehicles who essentially had to slam on brakes to avoid hitting us. After pulling off the road, I checked the oil and it was not even reading on the dipstick even though I had just filled it the previous day! There were no signs that anything was wrong prior to this; neither the oil lamp nor the check engine light came on. Now there is a loud rod knocking in the engine - AND the check engine light is still not on. The engine now needs to be fully replaced. All other 2017 Tuscon models have an engine recall, except this one, and I believe that is a gross mistake. This issue clearly falls in the same issues that has caused a recall on the other models.

Daughter had the car 2 months and went on a weekend trip. Three hours into the trip her tucson started to make a load noise. She pulled into a shop and had them check the oil but as soon as he started the car he refused to look any further and told her to take it to a dealer around the corner. As soon as she pulled in the mechanic said it sounded like a blowen motor. Now 2 months later still no car because hyundai would not return and claim reports and the dealer i bought it from thinks they should fix it because he has talked to local dealers and the agree. The local machanic took a look at it and said it blow a rod. From what i've found out that this is a common issue. There are no recalls for this vehicle. the car has about 95000 miles on it.

My Hyundai Tucson beginning at 65,000 miles Began consuming more oil than normal. There was a transfer of title through a family member with the vehicle and was not aware that in that case the cars 100,000 mile warranty is no longer valid. It is then reduced to half that or 60,000, one of the 2. I brought the fact up to the service rep at Hyundai that it was going through a lot of oil and they stated that it was normal with multiple cars that Hyundai produced. The oil was burning off and no detection of leak and no check engine light has ever came on. It never over heated. I then brought this up to Hyundai at about 92,000 miles and thats when I learned about the warranty being voided because of the transfer. The car at the time is running just fine but still burning oil and still nothing from the dealership about any issues because the check engine light never came on. Until I was going home one day and the car began to stutter and losing power . It was struggling to produce power and I finally pulled over to a safe spot. It did not wanna start after that. I had it towed to Hyundai service center and they later told me that my engine needed a fuel system flush. They did that and I drove it just fine for about a month. Then it did the same thing only this time the check engine light finally came on. The code was giving them a misfire of 2 cylinders and was not holding enough pressure. They then said my motor was gonna need to be replaced and that threw me off. I feel like that should have been detected much earlier but without any sign of overheating or engine alarms it just kept running up until that point of the motor no longer running. I feel that if I were to get some kind of check engine light earlier in then it is possibly that this could have been avoided. I feel like this issue remains and is well overlooked to many of their vehicles. I just need a new engine not looking for money or anything else, just a car that is reliable and safe.

So my engine has a lawsuit with Hyundai because the type of engine that is in it is causing it to consume more oil. My cylinder one has completely gone out because of it consuming to much oil. It is a huge safety problem because it could have shut off while I was driving it. Hyundai dealership is trying their best to not to have to pay for it. My check engine light came on and said spark plugs and coils needed to be changed. We changed them and they were coated in oil which isn't supposed to happen. My light was still on after changing them and the code reader was saying cylinder 1 misfire. I take it to the dealership and they said cylinder one has gone out. I think they dismissed it because the coils and plus were clean but we just changed them and maybe drove 10 miles so they wouldn't have had a chance to get coated in oil. I hope I don't have to get a lawyer to get my car fixed under the lawsuit like it needs to be. I know a few other people having the same problem and theirs is getting covered under the same lawsuit.

On 4/8/2023 I began hearing a ticking noise coming from my engine while driving. I took my car into Sid Dillon Hyundai Dealership of Lincoln NE on 4/10 and picked it up on 4/11. They completed 2 recalls (valve cap replace and ABS kit replace) and an inspection on the engine. The recalls did not fix the issue. They determined that the cylinder 3 rod bearing has excessive clearance of .37 MM. They advised that the vehicle should not be driven as it could lock up at any time. They found that the engine needs a replacement. I was quoted $13,000 for a new engine replacement. They let me know that there has been extended warranted for this exact issue on the 2.0 and 2.4 engine. However, my vehicle has the 1.6 engine which was not included in the extended warranty although it has the same issue.

Rear door on driver side suddenly won't open from inside or outside. The electric locks can be heard locking and unlocking but door handles do nothing. There are no messages or alerts. The concern is not being able to get someone out in the event of an emergency. There are many complaints about door actuator failures on the internet on several Hyundai models.

I believe the transmission is to blame as many others have stated. Our Tucson, without notice, quickly accelerates which is sometimes a scary situation. This defect can easily cause an accident. It happens often. It also sometimes lags when pushing on the gas and then accelerates as if I was in "sport" mode, when in fact I'm not. Hyundai has told me that there's nothing wrong with the vehicle so they won't look at it. That's obviously false as everyone knows now it's defective. No lights or warning devices activated.

My vehicle did not accelerate when I pressed the gas - also I am low on oil and I’m not due for an oil change, meaning there is an oil consumption issue with the engine. Something is wrong with the engine/oil.

The car was checked out by the dealer and they are recommending a completely new engine . They have no explanation for me.

It's like the transmission has hesitation before it decides to go. I step on the gas and it doesn't go right away, it takes a couple seconds and then the rpms go up really high. There has been no accident but this has happened many times.

Car stopped on highway. Car has 105000 miles and i have done required oil changes . Dealer states engine is no good

NHTSA ODI 11510511

The car has been having numerous acceleration issues, it can take upwards of 30secs to actually start moving from a light or stop sign. It also seems to be shifting late and/or slipping. This had caused me to be stuck at a light in the middle of the road and almost hit by another car. Also, my engine completely failed within 5mins, I was driving and the check engine light came on, then the oil light, then the engine started smoking, and then the car died in the middle of the road. The engine completely seized in 5mins. I had all oil changes done and there was never an oil light on saying it was low. When the dealer checked the engine there was no oil, probably from the rod breaking out. There. Was some if the same issues with the same year that got recalled and fixed for free. I got quoted $16,000 from the dealer. That's more than I owe and what the car is worth. I'm stuck with no vehicle and don't know what to do.
