Engine

36 reports7 fires
“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)”

Service brakes

“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]”

Vehicle speed control

18 reports1 crash1 fire
“Hyundai's current handling of recall 251 is inadequate, posing significant danger to drivers and passengers. Hyundai's remedy for Recall 251 replaces ABS fuse with a lower amperage fuse. While this may prevent fires caused by brake fluid leaks, it disables the ABS, introducing severe safety hazards: •Without ABS, the risk of wheel lockup during heavy braking increases, leading to skidding and loss of control. •ABS reduces stopping distances, especially on slippery surfaces. Disabling it may result in longer stopping distances, raising collision risks. •Drivers accustomed to ABS may not be prepared for how the vehicle behaves without it, potentially leading to improper braking. Federal regulations mandate that all U.S. cars and minivans manufactured in 2012 or later must have four-wheel ABS. By disabling the ABS, Hyundai circumvents this requirement, compromising safety. Despite attempts to communicate these safety issues, Hyundai has shown inadequate response. This suggests a disregard for customer safety and an effort to avoid liability and the cost of providing loaner vehicles or temporary replacements. Hyundai has not offered alternative transportation to…”

Service brakes, hydraulic

14 reports1 fire1 related recall
“The contact owns a 2012 Hyundai Accent. The contact stated that while driving at undisclosed speeds, the clutch pedal traveled to the floorboard and the low oil warning light illuminated. Due to the failure, the brakes failed to function properly. The vehicle was taken to an independent mechanic, who diagnosed and determined that the slave cylinder had failed and needed to be replaced. The contact was concerned that the failure was related to an engine failure recall, and that the dealer and manufacturer had failed to provide the proper repair during the repair, which caused the current clutch and braking system failures. The manufacturer was not made aware of the failure. The approximate failure mileage was 92,000.”
