I was traveling in Texas with my child on the highway going 65 when my vehicle went into limp mode and immediately started making a noise like a card in a bicycle tire and would not accelerate. After a few seconds the check engine light came on blinking. I managed to make it to an exit and pull into a gas station. I called a tow company and had to wait more than an hour in the heat with my [XXX] for them to reach me. I called the closest dealer which was aslo an hour away and made sure they were aware the vehicle was coming. A family member drove two hours to get us. A service tech texted me that night and told me the car was awaiting a tech. First thing Monday I received another text that a new engine replacement had been approved. It actually took several phone calls and trying to reach anyone to actually find out that the car had code p1326 and had failed the rod bearing test. And I read more about the gdi theta II settlement and reached out to customer care and opened a ticket to be reimbursed for towing. The vehicle had a previous recall completed for the knock sensor. No rental cars were available to me AT ALL. I received a remanufactured short block all said and done in 10 days. My family was left with no car for that time. There were no warning signs on my car-no excessive oil consumption, no other lights or noises. terrified it will occur with the replacement.

For a year my vehicle has this sort of loud noise, sort of a vibration , it has been consuming and burning large amounts of oil, to now where I'm having to put 1-2 Quarts of oil in a week. I was made aware from a mechanic at Hyundai there is a class action lawsuit for an engine defect where the rod bearing breaks which damages the engine and can cause either the engine to seize or catch on fire.. Hyundai refused to fix the engine until it is deemed a total loss despite them being aware my vehicle is already displaying the symptoms of this engine defect. This is so unsafe for not only myself and my family but other motorists .

The connecting rod bearing failed. The dealer has the car and has not provided me with detailed documentation as I have requested. I was traveling ~70 MPH on [XXX] in Maryland when the engine threw a rod. I could control the braking and steering, but had no ability to accelerate. I was able to magically go across 3 lanes of traffic and exit the highway to a safe resting place. I had the car towed to Porter Hyundai in Newark, DE. They inspected the engine and sent documentation to Hyundai. Prior to the event, no warning lamps were on. The "check engine" light came on as the incident was occurring.

Engine Failure with no warning at all. All recalls were resolved prior to the engine failure. I was on a 4 lane bridge that was 7 miles long over Tampa Bay in heavy traffic. The engine light started flashing, the oil light came on and there was a loud knocking noice. Traffic was going anywhere from 65-75+ MPH. I lost acceleration, had to turn on hazards to try to get over. It’s amazing that we were not rear ended and injured when this happened. The Tucson was running fine prior to the engine failure. The dealer notes display: 99947 - engine failed bearing replaced long block engine and road tested. The engine blew on 5/28/2023. The replacement was completed on Saturday July 1, 2023 when the dealer called to say it was ready. I had 99,947 miles on it and always kept up on maintenance and recalls.

Car keeps throwing "P1326 glow relay short circuit" code. This is the 3rd time it has happened in 3 weeks of driving it. Engine power is limited, engine is knocking and squealing, wheels are locking up while driving, engine keeps dieing while actively moving and accelerator is pressed. Just purchased the car in used market with 105k on odometer. At time of purchase dealer indicated the they had to put a new top end into engine to get it to run. This car is the most expensive LEMON I have ever encountered!

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-the federal safety agency-civil-penalty-barrier/
