The engine malfunctioned within the first 8 months of me purchasing the vehicle. It just randomly stopped working one day. The dealership was able to succesfully replace the engine under warranty (at least that-??s what they told me they did) however, the same issue arose another 8 months later. I-??ve done everything I needed to do as far as getting the oil changed and maintaining the vehicle. The engine light would repeatedly flash on and off so I assumed it was a malfunction because I just had the engine replaced. I took it to a local mechanic to get evaluated and they determined the engine was really bad and needed to replaced again. I reached back out to the dealership to notify them and they reached out to my extended warranty company. The extended warranty company denied my claim stating it is not covered due to the engine causing the insides of the vehicle to melt. Now I have a car that I am unable to drive due to no fault of my own.

2014 Hyundai Tucson bought used with 20,781 original miles in November 2021, thru an estate sale. On December 01, 2021, took the vehicle to dealer for analysis on an engine knocking noise that would not go away by driving it. I then researched the problem on the internet, and read these Hyundai engines had bad engine manufacturing defects, and regularly had engine failures, with some blowing a hole thru the engine block a causing fires. After tests at the dealer, they stated it had -??past-?? the engine knock noise test and I could bring in back at a later date for another test. They stated they could not do anything with it passing the noise test. I told him I could not use a car that was defective and not safe. I told him I knew Hyundai had settled engine failure lawsuits. No other attempts or offer was made. On 02/23/22, I took the vehicle to the dealer again for another engine knock noise test. I believed the noise was now louder and stronger. After being tested again, the dealer stated it past the test again, and they could not replace the engine without a failed test. The dealer stated to come back when it fails or makes a really loud knocking noise. I told him I did not want it to blow up on me or make me cause an accident on the freeway before they would act. They stated it needed to fail the noise test. I told them I did not like this at all. Was told to keep using it until it failed. On 09/22/22, I spoke to the dealer representative in person. He was very busy, I asked him to keep my engine noise case open on my car, as it was still making a loud knocking noise. He stated it was closed now. He offered no other further assistance on my problem, and started to talk to some else. I felt I was just blown off. Now, I guess they want the engine to blow up before any thing is done to fix it. I further believe they don-??t care if it causes an accident. Even though they know of the problem of engine defects, they refuse to just fix it with another engine.

On 7/29/2022 we took a trip with a 2014 Tuscan from from Boise Idaho to Worland WY. About 2 hours past Pocatello in a town called Kemmerer Wyoming the vehicle started to knock in the engine. As this happened the Vehicle started to derate its self from 80 MPH to 50mph and wouldn't accelerate past 1500RPMs. We pulled over and checked the oil and found metal on the rag used to check the oil. Ran a code reader and it read P1326. That means The Knock Sensor Detection System is tripped. In 2020 they fixed the sensers on most vehicles using the GDI engine because they would have a faulty trip. The tell tale sign that it wasn't a faulty senser was the engine knock and metal in the oil. We drove two hours the night before and didn't notice anything out of the ordinary. I would get oil changes every 3k to 5k miles. I checked fluids the night before when I left Boise. This issue came up with no warning. Turns out Hyundai has a life time warrantee on the GDI engine because they have major problems. They was a 1 Billion Dollar Law Suit against Kia/ Hyundai for issues during the manufacturing. This issue applies to the Hyundai Sonata, Santa Fe, Tucson and Kia Optima, Rio, Sorento, Soul and Sportage. Make sure to call Hyundai/Kia and they should replace the engine free of charge or give you a option to trade even if you DO NOT have a warranty. I attached a link that should prove to be helpful in researching this issue. https://www.safetyresearch.net/hyundai-kias-billion-dollar-engine-problem-that-broke-the-nhtsa-civil-penalty-barrier/

Engine light started blinking and I could not accelerate anymore. After driving home, I figured out it was showing P1326 error. It didn't allow me to go above 60 mph or 2000 rpm. Further digging into the issue I figured out that this was a common issue with hyundai and kia cars, but there was no recall for my car. I took the car to dealship as it was still under warranty and they only updated ECU for knock sensor. No other repairs where done saying that there was no solution to the issue. Other cars get their engines replaced and get lifetime warranty. I got no repairs or extended warranty.

Iba conduciendo mi vehículo por carretera y de momento se apago. Vehículo no quiere volver a prender. Vinieron del seguro, verificaron el vehículo y encontraron todo en perfecto orden, poleas, aceite, transmisión. Solo encontraron el motor que no corre. Adicional me indican que ya el vehículo no tiene garantía por ser yo segunda dueña, lo cual nunca me explicaron y lo peor de todo es que me quedan solamente 5 pagos. Nadie se quiere responsabilizar de dicha situación.

56k ish miles on my car, 2nd owner. Oil pressure light flickered on and off about.5 miles from home after 20 mile highway drive, steady on when pulled into driveway. Turned off car immediately. Have noticed excessive oil consumption but check and top off frequently. Topped off less than 200 miles prior. About halfway or less since last oil change mileage wise from what I recall. Checked oil and about halfway between bottom and top markers on dipstick. Took to dealer Monday (.8 miles from home). Oil light did not come back on. Dropped off. Dealer said light came on shortly after driving. Said problem could be caused by -??aftermarket-?? oil filter aka not a OEM filter. Said would do oil & filter change to see if resolved. Yesterday (Thursday) said oil & filter change complete & oil light not on. Reiterated previously mentioned concern of engine failure and potential accident. Service advisor said hyundai will not entertain engine replacement unless oil consumption gets documented. Oil consumption test to be completed after 1000 miles or until low oil levels noticed/oil pressure light illuminates. Will pick up tomorrow to see what happens. Engine is covered under newly extended warranty if failure occurs. Service advisor says nothing else was checked internally, spark plugs, etc. as this would incur engine being taken apart and extra charges prior to hyundai -??entertains-?? covering engine replacement etc. Although no failure has occurred yet I-??m worried something will and it will result in something potentially catastrophic for not only the engine/car but myself.
