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

I was driving over the Burlington Bristol Bridge on 3/15/2023 when my car lost power, with no warning. My check engine light came on and was blinking. I coasted over the bridge, immediately pulled over and had the car towed to my local Hyundai Dealer. I was told my car had no oil in it. My low oil light never came on ever. Dealer told me "someone probably didn't put enough oil in the car" I requested an oil consumption test. Drove the car for 1000 miles, came back and they told me the car was "fine" I drove the car another 1000 miles and checked my oil and was on the L. I would have ended up breaking down again. The code my car threw was P1326 which they told me was low oil, I found out that is untrue. It was a knocking sensor. My car burned 3 qts of oil in 2000 miles. It is completely unsafe to drive as I could lose power while driving and make it inoperable. Please help.

My engine is knocking and I was told after taking the car to the dealership that it is a rod making that sound but my car does not show up on the recall. I think something was overlooked and know of other instances similar to this.

I had recently just had gotten and oil change less than 2 months ago, I had to take my car back to the dealership because it was taking a while for the car to pick up speed. Once I took it into the dealership they told me my engine needs to be replaced. I know someone else that I know that has a hyundai as well and their engine completely gave out as well. What's going on with the engines. My car doesn't even have 100,000 miles on it yet, there's no way my engine should've gave out.

On the morning of April 22, 2023, I brought the vehicle in for a routine oil change and suddenly heard a loud knocking noise coming from the engine. The mechanic advised me to immediately bring the vehicle to a Hyundai service center. At no point was there any alert or warning sign such as a check engine light. I was left stranded with my newborn. The vehicle was brought into Freehold Hyundai in New Jersey for emergency service, and on April 25, 2023, I was informed that the vehicle needed a new engine.

I took the vehicle in for a recall for unrelated issues to this problem at 90,000 miles (July 6 2022). The technician noted that the vehicle was leaking oil and it needed an oil pan reseal. I brought the vehicle back for this service on March 6 2023. Between the initial recall service and this service, I noticed that the vehicle was consuming a significant amount of oil, beyond regular consumption. On several occasions, after about 1000 miles after the oil was changed, I was adding 2-3 quarts of oil to the vehicle. Moreover, when the oil was changed, the technician who changed the oil, noted that the oil was very dirty despite only going 3000-4000 miles between oil changes. I mentioned this to the Lehigh Valley Hyundai Service Desk and that it was highly unlikely that an oil pan reseal would resolve this. They ordered an oil consumption test and instructed me to drive the vehicle for 1000 miles. I did this and brought the vehicle back in to Lehigh Valley Hyundai on April 1, 2023. They checked the oil, the technician ordered an oil combustion cleaning, and instructed me to drive the vehicle an additional 1000 miles before bringing it back in for the oil combustion test. During this period, I noticed that the vehicle lost a significant amount of power. During a drive back from Widener University, I barely had enough power to drive up hills on the Northeast Extension and almost got into two wrecks due to the lack of power. I took the vehicle back to Hyundai on April 8, 2023 and notified them of this issue. They checked the vehicle out and notified me that the catalytic converter was clogged and needed to be replaced. They gave me a quote of $4000 to complete this service. This service was extraordinarily high priced compared to other mechanic services which cost between $2000-2500. I checked with other services and they indicated that they did not have access to the part and only Hyundai had access to the catalytic converter.

Engine fail, no warning till it happened, her car just stopped at night in the middle of the road while she was driving, she then smelled something burning and got right out of the car and called a tow truck. The car was towed to a Hyundai dealership where we were later told it was an engine block, and the car was basically burning gas. Cars been in the shop since January because the engine had to be shipped in parts from overseas. When the new engine had finally arrived, they took the old engine out and saw that the Pistons headshot shrapnel through the starter and through this turbo part, which is also now on back order. I do not know if the vehicle has been inspected by the manufacturer, or the police. I feel very uneasy about the safety of this vehicle given everything that’s happened and even though it’s showing that it’s not on the recall list from what I’m reading and what I understand everything that’s happened the vehicle should’ve been recalled. With the new findings of the shrapnel shooting through the car knowing that that could’ve been a catastrophic incident I could’ve killed my daughter is very unsettling. The car was purchased just under five months before this happened.

Engine stopped working without warning. The car is at the dealer, they are recommending a new engine and turbo.

I am having a problem with my engine consuming oil. I also had loss of power in the engine when I was pulling out on a highway which was very dangerous. I took the car back to the dealership and they replaced the whole exhaust system and said it was dirty. I had another part replaced last year that they told me was dirty due to oil. I have taking the car back to the dealership for oil consumption test and the engine is still consuming oil. It is dangerous to drive because the engine can seize or I can lose power on the road. I have been in touch with Hyundai corporation many times and nothing is being done. my car has been brought in to the dealership six times since October last year due to this issue. The dealership told me that they are replacing engines but they are refusing to replace mine. They admitted there is a defect in these engines.

Vehicle was parked for 2 weeks while I was out of town. I started the car and when I drove down the street, there was no acceleration or power. I turned around and went right back home. I checked the oil, and it was empty. There was no oil under the car. Having the vehicle towed to the Dealer 05/02/23. I am concerned about all of the complaints of exactly the same problem with the engine and want to document my situation.

Hi, I live in Levittown, NY, USA. I am a second owner of this vehicle. Currently, my vehicle has a knocking sound and car stopped working 4 times this week. Twice on a busy road, and I was almost hit from behind by another car. I also saw the company recall notice for my model describing similar problems. I took my car to local nearby dealer’Advantage Hyundai’ at Hicksville, NY for repair and spoke with service advisor MR. Patrick Lerouzic. First of all very rude person to talk to, he informed me that I have to leave my vehicle for more than a month at site, just to begin with the vehicle. NO assurance or time line when he will start looking at my vehicle and straight refused to provide any loaner car As the car is not safe to drive, I am forced to leave my car at dealer site and to wait for a month only to see if they will repair or not. My humble request to take a closer look at my request and to stop Hyundai officials to play around like mafia with manufacturers defect cars, and harassing customers of no fault of theirs. Best Rajinder

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.
