While traveling at highway speeds on [XXX] with three passengers, the vehicle suddenly suffered a catastrophic internal engine failure (severe rod knock), forcing an emergency deceleration in active traffic that put all occupants at risk of a rear-end collision. The sudden breakdown was immediately preceded by a flashing Check Engine Light and violent metallic knocking, despite the vehicle being regularly serviced and having a Knock Sensor Detection System (KSDS) software update completed just one month prior at Motor Mile Hyundai in Christiansburg. The catastrophic failure and the immediate need for a complete engine replacement have since been confirmed verbally by the Hyundai service center. Actual milage on engine is approx. 145000 (Because of replaced instrument cluster by previous owner it shows approx. 195000) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2015 Hyundai accent started having problems with oil consumption around 65000 miles. I got it checked regularly and the mechanic noticed it after it was having issues accelerating and losing power then cutting off completely. I had to constantly check oil each week or sooner. A couple months later it started losing power on high way and there was a clicking/ticking coming from engine. I pulled over and cut it off. Then drove it slowly (under 30 mph) to car store down the road to add oil but it was fine. Was able to get back home on back roads going slowly. Mechanic told me there oil consumption was a problem with these types of cars and likely causing engine problems. The whole time I had problems the check engine, battery, and oil light would constantly come on and go off. When they hooked it up to see why check engine light was on there were about 15 different codes. One of them being the Variable Valve Solenoid which I ended up replacing both first but still had problems. It would accelerate but there was still a ticking noise upon accelerating. I didn’t drive it for a few weeks then the day I was going to take it back to shop, My husband, his friend, and I were on highway a couple minutes from home and hit a bump and heard a loud thud when the ticking stopped but the car beside us was waving to get our attention that the car was on fire. There was smoke coming through a.c. And you could see it in the rear. My husband quickly pulled over and when I went to get out of passengers side, flames shot up my side of the door so I quickly jumped across out his side. We were able to all get out ok. Luckily there was a firetruck coming down the highway before I could even get ahold of dispatch on 911. The cars front end was engulfed in flames which they were able to put out quickly. The hood was roasted. I’m not sure if they determined the cause and my car is still sitting in the lot where they towed it. Unfortunately I had a lapse in insurance because I was out of work

About 8 months to a year ago my car started losing power and started using a lot of oil without an oil leak. Now it has a loud knocking noise in the engine. I have taken it to a mechanic and they said they some vehicles have recalls.

After seeing a mechanic the problem was a rod bearing connector failure which caused metal shavings to clog and restrict the oil flow, starting as a small knock and quickly turned into a loud horrible knock, power failure and ultimately my engine to seize. the same engine as the 2015-2016 Velosters recall, a 1.6L gamma gdi engine, the same exact issues and problems accrued and caused that’s specific model to recall, but I believe that many more models with this specific engine are faulty due to the same problem.

My car is experiencing the same issue as the recall on the engines for sonatas and Elantra in my year. My vehicle experienced a stall while in a drive thru the oil light illuminated and ever since then I have a ticking sound in the engine.

Purchased in January 2023 with 99k miles. Performed oil change on day 1. Checked fluid levels every 1500 miles, noticed oil was low, ( no smoking, no burning oil smell, no idea where oil was going?) began adding oil, and checking every 500 miles. Always about 1/4 quart low. Changed oil, and filter every 3000 miles. At approximately 119k, started hearing a small ticking sound, was told to use better gas, so began using premium gas. Didn't change the ticking. At 120k tick became a loud knock, after new oil/filter change (I changed oil early at approximately 1800 miles to try to alleviate tick. Decided to drive to mechanic shop when engine light came on and showed knock sensor code. I bought a knock sensor and replaced old one. Shop says rod bearing is causing to noise, and asked to see old oil which I keep in new oil containers.after I change, to dispose of at auto store. Bottom of oil containers was full of fine metal. Tell me the engine might have recall. However 2012 accent 1.6 gdi I not on recall, but 2012 veloster is, among others that use the same engine. I believe the recall on other vehicles is due to exactly what's happed to mine. Why is the 2012 accent gs not included in the recalls for engine replacement? I've emailed huyndia of America, and they say I am responsible for fixing the engine? I feel no amount of maintenance would have kept this from happening. I've thought maybe if check engine light had come on when ticking first started I could have taken car to dealer and that tick might not have became rod bearing clanking, and knocking? Please help to add 2012 accent to recall. Ive read many other stories describing the same problem. Thank you

Bought my car in 2021 and had actuators for windows replaced, now in 2023 I need passenger actuator replaced again. My heater is stuck on 4 and continuously blows and cant be turned off. The summer was ok but wasted gas because I had to have the air conditioner on or else eventually nothing but heat will blow out and so its not in my face the air has to blown in "feet" only mode and eventually starts to really burn while I'm driving. No coverage cause its considered "cosmetic" even though the whole panel needs to be replaced not just the knob. My car is also apart of the Hyundai recall #251 but when calling my local dealership they told me I had no remedy for any type of recall so that ment I had no recall. I called Hyundai Customer Service and asked about the notice to dealers, the notice lets dealers know that owners of effected vehicles are eligible for substitute transportation if they do not want to continue driving their car. I let him know what my local dealer told me, and how she didn't even let me know about the recall or the alternate transportation choice that's available to me and he just told me that they know about the recall so they should help just ask for a manager next time. I have my check engine light on now after hearing a ticking noise like other complaints, hot air constantly blowing and now I have to worry that whatever is wrong could also effect the problem that is considered to be likely to cause my car to catch fire! Please let dealers know just cause there's no remedy yet for the recall, please at least let people be aware that they are at risk of having their car catch on fire especially when they call and ask specifically for the information!

Engine has been causing a knock of some sort making the check engine light to constantly come on. Engine is the same engine as the Kia soul and those engines have a full recall to be replaced, the recall needs too be extended too the Hyundai accents. The engine began making the issue before 70 thousand miles as all mechanics only saying it's just a sensor when I the driver can hear a klack when driving after a half hour.
