Was driving down highway and vehicle lost power and shut off. Brought car to mechanic shop they ran a diagnostic and tore down the engine to see what the problem was. They found the problem was with oil consumption and carbon buildup. Oil was leaking through the pistons, piston rings into the combustion chamber, which in part was causing oil to go through the exhaust system. They found oil in the exhaust pipes and the catalytic converter and the exhaust manifold. The catalytic converter had to be replaced because it was clogged with all the oil that was leaking through the exhaust system from the combustion chamber. They found carbon buildup on the pistons, the piston rings and inside the combustion chamber

Yes, the issue has been confirmed by a local dealership, where they noted the jerking during acceleration and the high oil consumption. Yes, the vehicle has been inspected by the dealership, but it has not been inspected by the manufacturer or insurance representatives. There were no warning lamps or messages prior to the incidents.

I reported a problem with my engine to the Clay Cooley Hyundai dealership (Mesquite) in April 2022. I told them that my oil was burning a lot faster than normal. My car was currently under warranty at the time, which would have covered a new engine replacement. The dealership instructed me to do -??oil consumption-?? tests and had me come in every 1000 miles to see if there were any oil leaks. Once I completed the tests, they told me to do another round of testing, which I thought was odd. I ended up doing tests from April-October 2022, and by the time I was finished my warranty expired. They said that my engine was fine and good to drive. I took my car to the same dealership in August 2024 with the same issue and that my engine wasn-??t accelerating. They are now telling that there is a problem with my engine and charging me a new one for $10k. It would've been covered under my warranty in 2022, but they had me drive over the warranty limit so that a new engine wouldn-??t be covered anymore. After doing research, there was a Class Action lawsuit about the engine for my vehicle. The problem is damage to the engine-??s connecting rod bearings. You could hear a knocking sound from my engine. This issue has been happening from 2022-2024. I had to do oil changes more frequently. After consulting with a local auto care shop, they said it was a manufacturing problem. Hyundai put me back on the road with an unsafe car. The engine should have been fixed back in 2022. Hyundai Corporate is only offering to pay 50% of the engine (I would have to pay $5k-8k). I feel like they knew about the bad engine because of the lawsuit, and the reason I had to do a second round of tests was to drive over the warranty mileage.

My engine in 2023 was burning oil excessively, which caused my CAT to become clogged. I was unable to drive the vehicle and had to have both replaced by Hyundai. I paid partial for the CAT. A year later now in 2024, this -??new-?? engine is doing the same and my new CAT is clogged again. I had to add oil continuously. Now they are refusing to fix anything

The engine is consuming extreme amounts of oil. 1-2 quarts a week. The oil light does not alert that oil is low and could cause a very dangerous situation. My car was running and just stopped while driving because oil had coated the spark plugs. Hyundai refused to honor my warranty. They want the car for 6 months to put new motor and only after I pay $1000 for a cleaning when they even admitted it was a known problem and I should "try to sell the car as fast as possible and not mention the oil consumption" I've continued trying to get them to correct this since November 2023

On [XXX] my daughter was driving in Meridian Ms and when she was at a red light the 2017 Hyundai Tuscon that she was driving started shaking and all the lights on the dashboard came on and she couldn't drive because it wouldn't move. She called a tow truck to have it taken to Firestone. When they looked at it, they said the reading was spark plugs and fuel injectors that needed to be replaced. After they did that, the car still would not work. We paid $1300 dollars for them to do this. We then had it towed to Hyundai in Flowood Ms. We learned that the whole engine needs to be replaced. We Take very good care of our cars and this shouldnt be happening. I see that there is an extended warranty for 2017 tucsons with engine failures, but our particular engine is not included in this. We have a turbo 1.6. I asked Hyundai why these particular motors are not included and they didnt know. I found alot of people are having the same engine issues as I am and i think Hyundai needs to help me out. The replacement cost of this is going to be about $10000 dollars. My car only has $84000 miles on it. Hyundai knows that there are problems with these vehicles but refuse to be any help what so ever. I just dont understand why my engine isn't included in their $150000 mile warranty. I dont know where else to turn for help. Thank you.

Took my 2017 Hyundai Tucson 1.6t engine into the service center on 8/21 for a check engine light and Bluelink notification of "A possible condition with your Engine Control System has been detected" that came on Sunday 8/18. Service center diagnosed P0326 ($159) From the service center: We have pulled code P0326 for an issue with the knock sensor readings. The vehicle can sue an oil change as is due and there is a gasket leak which sounds like it is from turbo or manifold gasket which is causing that rattling noise you're hearing. Below is the three itemized recommendations for this vehicle. 1) Knock sensor replacement -$635 +taxes installed 2) Oil change recommended $ 85 +taxes 3) Turbo gasket replacement $205 + taxes installed. I bought my car in 2020 and only have 53,000miles on it and was told it's out of warranty so this isn't covered - even though the 2017 Tucson's are recalled/warranty for life for engine issues for the same exact reasons mine was brought in for. This is my second hyundai, which I have always loved; however, I am disappointed in the quality of car not being up to standard due to manufacturing, and I am paying the price for it. The10yr/100k mile and 5yr/60k mile warranty advertising is misleading and deceiving. If I could go back, I wouldn't have bought a hyundai

The vehicle has 83,000 miles. It burns through 10 quarts of oil per 5,000 miles. No oil or check engine light comes on. Twice It has been dry when having the oil changed. Additionally, the vehicle suddenly started to jerk and misfire, the check engine light came on. I was within a block of my home and was able to return home. This would have been extremely dangerous in traffic. I have changed the coils and plugs, but it continues to hesitate and run unevenly, just like so many other reports.

I am not a mechanic, but I know that my engine consumes 5-8 quarts of oil every 3000 miles. In addition to the engine oil consumption problem, I have noticed a severe burning smell in my car cabin, especially on takeoff, but it lingers. Unfortunately, I have to breathe this in every time I drive my car, and it is making my headaches much worse. I have taken my car to a private mechanic's shop, and the mechanic noticed the problem during two previous oil changes. I have not yet taken my car to the police or insurance company. There have been no warning messages or lights illuminated on the dashboard.

I purchased a 2017 Hyundai Tucson with a 1.6L Turbo GDI engine. After just one month, the engine developed bearing damage. It seems that this problem is common with this type of engine. Does Hyundai have a recall for this engine model?
