2018 Hyundai Tucson Engine

My connecting rod came apart and went through the oil pan while I was on the highway. There were no engine or oil lights until the engine was already smoking and no longer accelerating luckily I was in the far right lane already and was able.to coast to safety. Hyundai is also refusing to honor my warranty. It requires a completely new engine. So this was a catastrophic engine failure with no warning.

I own a 2018 Hyundai Tucson with 87,000 miles that consumes about four quarts of oil per 1,000 miles. I first noticed the problem at 51,000 miles, despite regular maintenance. The issue has worsened, repeatedly damaging spark plugs and causing the car to seize. Hyundai has denied my request for a replacement engine because I am the second owner. I bought the vehicle at 26,000 miles, believing it carried the 100,000-mile warranty. I was never informed that coverage drops to 60,000 miles for second owners. I have maintained the vehicle with oil changes every 3,000 miles, yet it remains unsafe to drive long distances. This defect presents a serious safety risk, and Hyundai has not provided a resolution.

There is a very well known issue with Hyundai (and Kia) and oil consumption issues, no recalls have been issued yet and I am another person dealing with this without any real support from Hyundai to solve the issue. In 2024 I did an oil consumption test, they found it was burning oil excessively and I had to pay $700 out of pocket for a cleaning they recommended. Afterwards it was burning only 1 quart every 1k miles which they said is acceptable so we moved on. Less than a year later I am still dealing with this issue only it has gotten worse, I am burning 5-6 quarts every 1k miles. I do keep up with my oil changes, I now have to check it and top it off almost daily, and even without being a car expert I know that something HAS to be done... why aren't there any recalls yet? Despite keeping up with my maintenance, there are other issues that can be related from this issue, including the engine stalling or skipping which is a safety issue when driving.

The engine on this vehicle burns oil quickly which is a known defect. I took the vehicle to the dealership and both times I was told everything was working fine. On 12/5/2025 the vehicle just lost power while driving. After getting the vehicle towed to a mechanic they said I needed a new engine.

It's an engine failure. The car died in the middle of the rode at a traffic light with busy traffic flowing. It was confirmed by a independent service center. No one other an the independent service center has inspected it. There were no warning lamps or messages before failure.

Since I purchased the car in 2018 I took great care of it, keeping the services going on time. But recently in October 2024 even tough I did services the oil service’s sign keep on showing up. I then schedule an appointment with a dealer ship near my area in January and they told me that they were no oil in the car. But I show them the date ans mileage on my stickers I specified that is the reason I am here and to double check for me for filtration because something is wrong, they told me that the car was fine. Days after I had to go in my regular service place for another service and on May I drove the car from Massachusetts to New York and in the middle of the way car start shaking, making noise and when I drove it to a shop they diagnose a failed engine. I left the car in Goshen NY in a Hyundai dealer ship and they told me a valve un the engine was burned and that where the problem came from . They said , they fixed it. A friend pick up the car and 30 mnt driving it police came to rescinde her in the highway, they then told me that’s it’s was a failed engine and days after ask for services record, I provide the last 6 times , they asked me from 0 until today. The shop were I take care of the car don’t keep record from so long. Talking about 2018. They said they won’t fixed it without those record . The car is still under warranty with 71321 miles and I have it for 7 years.

Engine had oil consumption problem. We bought it as second owners around 89k miles. Now at 98k miles and engine has blown. It’s not going to be fixed without a replacement. We are getting the run around by Hyundai in ballwin asking us to pay 500 upfront and all kinds of pushback. We have to tow and they will look at it even though it is still under 100kmile powertrain warranty. We got 3 months use out of a vehicle we just paid 15k for. Total loss

I own a Hyundai Tucson 2018 model and recently it started making the noise. i got it check with the private auto shop and they said it the engine issue so i took it to dealership as it was under the 100,000 power train warranty. The dealership ask me about the invoice of regular oil change invoice which i provided to them but they simply denied it. the dealership is located on route 1 south Brunswick new jersey.

I was driving my car and the engine started knocking and when I stopped the car kept stalling and losing power especially going up a hill. I had oil in the car. I bought the car to a repair shop and the mechanic advised me to go to Hyundai because they’re having problems with the engines in the Tucsons. I found out they extended the warranty from 100k to 150k so I’m covered I thought. They started diagnosing my car and they said the engine needs to be replaced. They contacted Hyundai corporate to dis cuss this. Corporate said they’re no t responsible for this because there was sludge in the engine. The car has 103k miles on it. The diagnosis charge I owe so far is about 400.00 Hyundai corporate wants further diagnosing of the engine. The dealership said Hyundai corporate said I have to pay the additional diagnostic charges of approximately 900.00 before they’ll determine the outcome of my claim. I don’t think it’s fair at all. I believe they should be paying for information they’re requesting. I’m having a hard time with Hyundai corporate with this runaround they’re giving me. I do t l ow what else to do? I can’t afford to pay for an engine replacement that they should be responsible for this problem. I hope I’ve proved enough information. Thank you sincerely.

The contact stated that the check engine warning light illuminated and was flashing off and on. The accelerator pedal was depressed; however, the vehicle failed to respond as needed. The contact pulled over to the side of the road, and the vehicle remained running. The contact waited for a while and then shifted to drive(D) and was unable to accelerate above 30 MPH. The contact stated that the failure was a recurring failure. The vehicle was taken to a Parts Store and was scanned, and DTC: P1326 was retrieved. The contact had not taken the vehicle to a dealer or to an independent mechanic. The vehicle was not diagnosed or repaired. The contact was no longer driving the vehicle. The manufacturer was not informed of the failure. The failure mileage was approximately 102,000.

Excessive oil consumption (failed 3 tests) now adding two quarts a week.... Transmission shifting issues (already had a replacement at 65,000 miles. Hesitation with acceleration. AWD and can barely make it up my driveway. Rpms rev when trying to go slow. Already needed a moonroof replaced because the motor died. USB randomly disconnects and reconnects for GPS.

I noticed my vehicle was burning through oil, initially indicated by a P011 code, when I called Hyundai they said its often a symptom related to low oil pressure. After oil changes, the code would clear, but it returned multiple times, and on two occasions, the dipstick showed no oil when checked. Despite staying current on oil changes and maintenance, I was dismissed as excessive oil burning being “common” for this engine. After recent recall updates at the dealership, a technician confirmed excessive carbon buildup and that my catalytic converter was beginning to plug. I inquired about an extended warranty offered due to the knock sensor installation but was told it only covers rod bearing failure. Hyundai Corporate echoed this, stating no coverage until catastrophic engine failure occurs, despite the ongoing damage from oil burning and converter clogging. Since my visit to the Hyundai dealership, the symptoms have rapidly escalated. Now, my vehicle is extremely loud and acceleration is poor. It takes a long time to get up to speed, and I worry about driving it as it may result in an accident.

The contact owns a 2018 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the low oil warning light illuminated. The vehicle was taken to the dealer, who informed the contact that the vehicle was abnormally low on oil even though it had been less than 3,000 miles since the previous oil change was performed. The dealer instructed the contact to drive the vehicle for 1,000 miles and then return as part of an oil consumption test. The contact stated that after the oil consumption test was completed, the contact was informed that the engine was consuming an abnormal amount of engine oil; however, the dealer had not provided the cause for the failure. The vehicle was not repaired. The manufacturer was notified of the failure but did not assist. The failure mileage was 35,000.

74,000 miles Excessive oil consumption, 1 quart per 1000 miles. Low oil pressure warning. Oil warning light, repeated and various codes. Noticeable ticking/clatter at startup. Not included in current recalls.

Had oil consumption problems for a while started around 60,000mi. I got regular and frequent oil changes and the engine seized up at 94,000mi while driving. Hyundai refused to take accountability.

On Saturday, November 23rd, while driving down the highway the check engine light came on and the car would not accelerate past 40 mph. When accelerating from a stop, the car's acceleration is greatly diminished. The car was checked out be a local Hyundai dealership. After running a diagnostic, the mechanic reported the following: the car has a knock sensor code, valve stem seals are leaking a little bit, compression test showed low compression on all four cylinders (between 130 and 140) normally it is 185. This indicates wear in the rings and losing compression that way. Dealership says only option is to replace the engine. Currently have 95k miles on the car. I believe we are the second owners of this car.

my mechanic and I noticed that motor oil engine is running out too fast that is normal. I take my suv to do oil change every 5,000 miles, I can't even wait the 5,000 miles because the oil level is low, he double check for any dripping of oil. my mechanic told me that it is not safe drive the car in low level of oil because it can cause a fire in the engine. I went to the hyundai dealer to explian them the problem and they told me there is nothing they can do to fix the issue because my manufacture guarantee is over, I don't feel safe to dive my car in that condition so thats why I'm here making this request to hopefully you guys can help me. the most important thing is the safe of my family.

The vehicle has been burning oil at over 3 quarts every 800-1000 miles. Hyundai has denied all claims to do anything about it after testing and seeing that it is burning the oil. This is a safety issue as it can clog the Catalytic converter and/or lose power while driving. The vehicle has 90,000 miles on it.

We were consuming about a quart of oil every week and a half. I drive over 60 miles a day. We added oil until we could check it out. First dealership said that no visible exterior leaks so they told us to take to Hyundai. Once at Hyundai we were told compression was down and we needed a new engine, Catalytic converter, and turbo. Our extended warranty only approved a short block. Said we have sludge and we have to cover the rest of the parts that have sludge but we proved our oil changes and used synthetic oil. They will not give us proof of anything. Hyundai is known for this and won’t cover anything. Hyuandai Beaverton and Ethos is being horrible.

Oil is burning VERY quickly. Less than 1qt draining when performing oil change.

My oil is being consumed for no apparent reason. I checked it one time and there was no oil in there. I keep checking it and adding oil. There is a recall for the issue but my vehicle is not on the recall list. I was not in a accident but the issue could cause bigger problems.

Car had been burning oil very quickly. I took it for an oil change, before it was due, and they said it was very low. They changed it, and I was leaving to visit my parents in Florida the next day. I checked the oil when getting there, and it was good, and I also checked it prior to heading back home, and it was still good. I was in a really bad/unsafe area at 10pm, on my way home from visiting my parents, and my car began to stall. Engine light came on. It would stall really bad when going slow, and almost died a couple times at lights when stopped, but we made it home. We got it to a mechanic, and they stated it was the engine, and it needed to be taken to the dealership. I have read that Hyundai/Kia are notorious for engine issues. My car was towed to the dealership, and they supposedly requested to see if Hyundai would cover for a replacement engine. My car is unfortunately 10,000 over the warranty mileage (100,000), but 110,000 is still not enough to be already having engine problems. Supposedly, according to the dealership, Hyundai declined, and the quote for a new engine is $7,693, which I cannot afford, especially on top of my car payment, which I still owe a good chunk on.
