    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.

    Back in March 2024 I had a tow beam stock replaced to the car. Couple of months after this check engine light started coming on until it stayed on. Took SUV to mechanic shop in July 2024, and they informed of a r&r knock senor needing to be replace. A couple days after this had to go back as check engine light was back on. they informed of needing to replace a wire harness. It wasn't a week after this that when starting the car you hear a very loud knocking sound. Like something is rattling around inside. After this no longer able to drive car as not sure what will happen next.

    In May 2024 my Hyundai Tucson died in a middle of an intersection with no warning. Worse than that is Hyundai motor USA informed me that the car was on a recall list for an engine failure issue that was apart of class action suit . Ans further told me that that were obligated to have the highway transportation safety dept notified first consider cause of the issue. They told an inspector from your department was required to inspect vehicle before repairs could be started and or returned fo me. That has not happened and they are using your office as the reason for delay on my vehicle. They have systematically m supplied the same answer to my case with no resolution. I have done everything I can as a consumer to handle my case and believed that they were going through the correct process but the dealer has informed me their own manufacturer and corporate is not following guidelines and handling recalls. This is soo dangerous as this vehicle was Already on a list for recall repair and they did NOT inform me the customer when it was brought in for repairs before this incident.

    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.

    I was traveling on the freeway at Highway speed, heard a loud knocking sound coming from the engine that got progressively worse. No warning lights, began to loose power as I exited the freeway. Had vehicle towed to dealership, they were able to replicate knocking noise coming from bottom end of engine. Diagnosed as catastrophic engine failure and needs engine replacement, outside of standard warranty. Engine is a 1.6L GDI and model was not included in recall for KSDS sensor. Safety was compromised due to engine failure at high speed with no warning or previous engine problem. Vehicle is available for inspection as of current date

    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.
