On December 28th, 2024 I was driving my SUV on the highway at highway speeds. I bought the suv from a Manchester Acura dealer on November 9, 2024. I am the second owner. While driving, the check engine light came on. I was able to complete my drive, but the car idled very rough. After getting the car home, my father checked the oil. It did not register on the dip stick. He put in about two quarts of oil. The check engine code was P0302, which is misfire in cylinder two. He proactively changed the spark plugs since the car had 92,000 miles on it. After changing the plugs, the code did not clear and the engine continued to idle rough. He did a compression test and confirmed that cylinder two had less than 50psi compression vs the other 3 cylinders which were at 170 psi. He also removed and inspected the new plugs after running the engine and cylinder 2 plug was already dark and oily whereas the other plugs were in as new condition. I opened a case with Hyundai Care America. They instructed me to take the suv to a Hyundai dealer for diagnosis. The verbal report of that diagnosis was burnt valves on cylinder two. The dealer stated that HCA would not cover a repair or engine replacement. Hyundai forums and NHSTA complaints are numerous around high oil consumption and burnt valves on Theta II engines. Hyundai needs to be held accountable.

My Engine malfunctioned while driving on the interstate at 70 mph. There were no lights that came on no notice just stopped excelerating. Thankfully after exiting the interstate I was able to get to a gas station safely and that is where the vehicle died altogether and would not start again. My husband and I checked the oil at that time and there was absolutely no oil in the engine. The worse part was that my husband had just put 3 quarts of oil in the engine on Sunday and this all happened on Friday of the same week. I work from home and had only traveled 300 miles that week total, so there was no reason for this to have happen. I had it towed to the car shop and they informed me that Cylinder 1 and 4 are not getting any compression at all. I just had the oil changed in this and am very good about keeping up on maintenance in my car. I have had problems with the oil pan cracking, got that fixed. I check my oil every time I put gas in the car due to the fact that I knew the engine was using oil but it was nothing this severe. I would only have to add one or two quarts of oil every other week and I drive a lot for my job. I have never had any lights come on to warn me, there were no noises that was coming from the engine, I did not have any discolored smoke from the back of the car when starting it. There was never any leaks on the ground either. I had a Hyundai Dealership in Springfield, IL look at it and they said it just eats oil nothing more. I had my mechanic look at it and he stated that I needed to keep a very close eye on it, so that is what I did. However, no one told me that this was going to happen. Now I am stuck with car and payment that I can not drive. No recall but several/hundreds of complaints on same thing? And NO RECALL????

The engine in my 2017 Hyundai Santa Fe Sport, specifically the 2.4L Theta II engine, failed and is available for inspection upon request. This failure caused the vehicle to stall unexpectedly while driving, creating a serious safety hazard due to the sudden loss of power and control. The issue has been diagnosed by a Hyundai dealership, which confirmed the engine requires replacement due to internal failure. The manufacturer has denied warranty coverage, alleging maintenance neglect by the previous owner. Prior to the failure, the Check Engine light illuminated, the vehicle began making knocking noises, and it experienced a loss of power before stalling.

The crank shaft failed leading to total engine failure. It's currently sitting at my mechanic's shop until I can get this sorted out, it can be inspected upon request. My engine failed while driving 75 mph on an interstate and could have lead to serious injury/death of myself, my passengers, and other drivers around me. The problem has been confirmed by my mechanic, an independent service center. I had complained to my local dealership service department a year or so ago about the amount of oil my car was going through, and was simply told "that's just an issue with this make/model" so was essentially told to live with it. The vehicle has not been inspected by law enforcement or an insurance company. I had the oil changed on 11/30/23 to ensure it was full while travelling. The oil light never came on. The check engine light had come on about a year prior, was checked at my local dealership service center via computer scan, and was told they couldn't find an issue. When I had my vehicle taken over to the mechanic, his reaction was "Oh geez, not another one." Apparently he has had to replace several of these Theta II 2.4L MIP engines recently.

The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated while driving at various speeds, the vehicle was consuming an excessive amount of engine oil. No warning light was illuminated. The vehicle was taken to a dealer where it was diagnosed, and it was determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The approximate failure mileage was 114,000.

I am reporting a Theta engine problem. This is a well documented problem across the nation. My car started knocking and losing oil after I bought it. At one point, I had to tow it to the dealership because the check engine light was flashing and the car was knocking and shuddering so bad, they told me not to drive the car any further. I have had the car back in the dealership several more times since then. The car currently has 110,000 miles on it, but the problems started before 100,000. I have contacted Hyundai, and they have told me that they won't do anything. They told me that I have a Theta engine and I have to go through the lawsuit. When I contacted the lawsuit, my car wasn't on the list of cars in the law suit even though Hyundai says that my car is one that could have the Theta engine. I had to continue to drive the vehicle and it is a safety issue at this point. The dealership said I had to drive it until the engine completely failed. That is a huge problem with safety. If my engine fails as I'm going up and down the mountains, it could cause me to be in an accident and it could cause me to hurt others. According to the articles that I have read, an engine failure can cause the rod to go through the engine and cause a fire! I know that cars can fail at any time....but when you know that your engine could fail at any time because of a manufacturer defect, that is a safety issue! I have done regular oil changes and done all the maintenance on this vehicle. My mom has let me borrow her car so that I don't have to drive an unsafe vehicle. I don't think that I should be financially responsible to replace this engine. Please let me know if you have any questions. The car is available for inspection.

All the ABS, Traction Control lights come on at various times. They will stay on for hours to days and then go off. I asked Hyundai to fix it, even took a pic with me when I was there last, and they said there was nothing wrong with it. It still does it. I don't know if anything is actually wrong, a bad sensor, or what. It has been doing it for 2 years. The speed of the vehicle does not matter. When it comes on, it can be from start or during driving. Sometimes restarting will solve it. Not always.
