What 152 owners told NHTSA about the 2012 Hyundai Accent 5

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)

UNKNOWN. I THINK THE ABS MODULE LIGHT APPEARED INSTANTLY ON THE DASHBOARD. IT'S THE ANTI-LOCK BRAKES THAT AREN'T WORKING. I IMMEDIATELY CONTACTED MY HYUNDAI DEALERSHIP WHEN I SAW A BRAKE LIGHT COME UP ON MY DASHBOARD WHEN I WENT TO BRAKE BUT I HAD NONE AND THE BRAKES WENT ALL THE WAY TO THE FLOOR AND I ALMOST WENT OVER A CLIFF AND DIED OR BADLY HURT OTHERS OR MYSELF IN A CAR ACCIDENT. I'M WILLING TO TRY AND GET IT FIXED AT OTHER INDEPENDENT SERVICE CENTERS IN PLYMOUTH MASSACHUSETTS. THE EVENT HAD HAPPENED A WEEK BEFORE BUT I DIDN'T REPORT THIS INCIDENT TO THE POLICE, INSURANCE REPRESENTATIVES/OTHERS OR ANY OTHER MANUFACTURER BECAUSE THERE WASN'T OFFICIALLY ANY AUTOMOBILE ACCIDENTS. FINALLY, MY HYUNDAI ACCENT 2012 WAS DONATED TO ME BY "GOOD NEWS GARAGE" OVER 2.5-3 YRS AGO THROUGH A WORK-TO-PROGRAM/DONATION UNDER THE M.R.C. OR MASSACHUSETTS REHABILITATION CENTER IN PLYMOUTH MASSACHUSETTS WHICH IS PERMANENTLY CLOSED AND IS NOW CALLED MASS OPTIONS AND THAT'S THE ONLY THING I KNOW ABOUT THIS SITUATION WITH NO BRAKES. PLEASE HELP ME. I NEED TO KNOW MY NEXT STEPS. THANK YOU! OWNER AND DRIVER [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On the [XXX], my 2012 Hyundai Accent caught fire in the engine compartment and engulfed in flames. Right before the fire started, smoke came out of the air vents into the car, causing me to become stifled and choke for several minutes. Smoke was also coming out of the hood. At that point, I lifted the hood and there were flames coming out of the engine. During the past six months prior to the fire, I developed a chronic cough and now believe it might have been attributed to fumes that I have been inhaling through the air vents from my car's engine. My [XXX] mother and [XXX] son have suffered headaches, coughing, sore throat and congestion when riding in my car with the air conditioner turned on. The remains of the vehicle were inspected by the Rockdale County Fire Department after they extinguished the fire. What remains of the car is available for inspection in Rockdale County Ga at a tow yard designated by the Rockdale County emergency rescue team members who assisted me. It was too damaged to tow to my home. There were no warning lamps, messages or other symptoms of the problem prior to the engine catching fire on [XXX].

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

Loud ticking and engine knocking. Car starts to stall and overheat, car does not shift properly. Was told it was failing coils. Replaced all coils and spark plugs, this remedied the flashing ck engine light. Check engine light still on and still says the coil is not responding. Tech says it is a stuck lifter but can't be manually unstuck. Road hazard is car will stall and engine will fail without warning. Car has received regular oil change maintenance.

When the car stops at a stop sign or traffic light the engine sometimes stalls and the engine and EPS warning light turn on. Also sometimes when trying to accelerate, acceleration is not possible, especially on the highway. This is a major safety risk of rear-end accidents.
