2013 Hyundai Accent Titusville, FL

VEHICLE SPEED CONTROL

The incident started August 15, 2025, I was driving my car and the traction light came on I stopped and turned it off. I proceeded to drive it after that and came home. Then I noticed my brake lights were constantly on so I took a piece of cardboard and folded it in a few folds and put it between the brake pedal and the brake switch it turned it off. I then proceeded the next day to drive my car it was doing fine until my caliper seized on my rotor and left me stuck on the side of the road, I then called a mobile mechanic he came out replaced the caliper on the left front driver side it still did not unseize my rotor for my caliper to move freely so he installed a new master cylinder it worked for 2 days then I was always driving it felt like the tire was falling off the car a lot of shaking and bouncing. So I parked it that unfortunately sees the caliper on the rotor again three times. I had a new caliper put on it worked for a week my traction light was off. And then my traction light came back on as I was driving it seized up again I've replaced a lot of fuses, new Masters cylinder, new caliper, new brake switch. I'm at a loss help me!!

2019 Hyundai Accent Menchaca, TX 1 injured

VEHICLE SPEED CONTROL

I am reporting a severe and hazardous failure involving my 2019 Hyundai Accent. On August 8, 2025, between 9:00 p.m. and 10:00 p.m., while driving on Mopac (Loop 1), a heavily traveled highway in Austin, Texas, the vehicle abruptly experienced an overheating issue without any prior warning. The engine rapidly lost power, causing the vehicle to become unstable in traffic. I managed to maneuver the vehicle to the far-right shoulder, but when I attempted to accelerate and further distance the car from the road, the engine failed completely, emitting a severe sound resembling an explosion followed by an immediate shutdown, rendering the vehicle inoperable. This failure posed an immediate safety hazard. The vehicle was disabled in a dark and high-speed traffic environment, significantly increasing the likelihood of being struck by other vehicles. During the incident, I encountered difficulty releasing my seatbelt, briefly confining myself inside. The sudden breakdown caused me severe distress, leading to a panic and an asthma attack. Although I did not seek medical attention, the physical and emotional consequences were substantial. Since the breakdown, the vehicle has remained completely undrivable and incapable of restarting. The issue has not been replicated due to the vehicle’s inoperability. Prior to this occurrence, I had maintained regular oil changes and performed necessary maintenance, and no warning lamps, error messages, or symptoms manifested before the failure occurred. The manufacturer has been notified, and I am awaiting review by a case manager. The vehicle hasn’t been inspected by a dealership yet. Following the towing of the vehicle to my residence, a mechanic was dispatched to conduct an inspection. The mechanic indicated that the engine may require replacement. However, insurance representatives subsequently arrived and were unable to provide assistance. They asserted that the issue was of a technical and electrical nature and deemed the vehicle a tot

2016 Hyundai Accent Easton, PA

VEHICLE SPEED CONTROL

The Emergency brake light, ABS light, and esc light all come on while driving & speedometer goes to 0. The speedometer also stops tracking mileage when these lights come on. This used to happen on & off, but now it’s almost permanent. Hundreds are reporting the same exact issue online, but mechanics cannot figure out what the problem is. Me and countless others have taken the vehicle to mechanics multiple times with no resolve and thousands of dollars worth of diagnostics that are incorrect and don’t resolve the issue. It is dangerous because we don’t know how fast we’re going, and we don’t know if your abs, emergency brakes, & esc are all working properly. This issue is impacting Hyundai Accents years 2015, 2016, & 2017 based on the multiple threads & posts online. I think it’s related to electrical issues too because my windshield wipers & blinkers will randomly malfunction while this is happening. A random online user said that it is a “SMART Junction Box” issue that needs to be replaced. Please look into this and issue a recall because thousands of people are spending thousands of hard-earned dollars with no resolve.

2022 Hyundai Accent Tacoma, WA

VEHICLE SPEED CONTROL

The instrument cluster malfunctioned and turned the dashboard off repeatedly in 2023 and now again in 2024. This part controls the cruise control, as well as the electrics on the dashboard. When it malfunctions, it deaccelerates the cruise control and you don't know what speed you are driving. The component was replaced in 2023 and is scheduled to be replaced, again, in two weeks. There is no warning when this part is going to malfunction and turn off and on.

2012 Hyundai Accent Mililani, HI Fire

VEHICLE SPEED CONTROL

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 affected drivers. Given these safety risks and Hyundai's inadequate response, we urgently request NHTSA to: 1.Ensure Recall 251 Remedy does not compromise safety by disabling the ABS. 2.Hold Hyundai accountable for maintaining four-wheel ABS in affected vehicles. 3.Require Hyundai to develop a safer recall remedy that: oFixes the Root Cause: Properly addresses the brake fluid leak to eliminate the fire risk without compromising the ABS. oMaintains ABS Functionality: Ensures the ABS system remains fully operational. oProvides Safety Support: Advises vehicle owners not to drive affected vehicles until the new remedy is implemented and provides loaner vehicles or temporary replacements. We urge the NHTSA to take immediate & decisive action to compel Hyundai to develop a safer, more effective solution.

Due to the recall of the ABS fuse I believe it has caused a electrical short and that's why my junction box does not work, also I had problems with slow acceleration almost causing me to get hit.

2020 Hyundai Accent Fort Worth, TX

VEHICLE SPEED CONTROL

My vehicle does the same thing as NHTSA ID Number: 11423521 and now I know not to bother taking it in for service for this issue. I was validated when I read that complaint as I have and continue to experience the same non-responsive issue when I accelerate from a complete stop ever since the vehicle was purchased 2020 February. This form asks for a specific date but there is no specific date. It happens every time I drive the vehicle. The issue can be erratic and I never know when I can or can’t depend on the vehicle’s acceleration and live in fear of causing a wreck or worse inuring / killing someone else. I get honked at all the time from impatient drivers insisting I pull out while I wait to make sure there is more than enough time to pull out and accelerate safely. Impatient drivers be hanged and pay attention to your own driving.

ON 2/11/21, I WAS DRIVING NORTH ON I294 WHEN I SUDDENLY LOST ACCELERATION. I HAD SEVERAL NEAR MISSES WITH A SEMI AND THE VEHICLES BEHIND ME. I PULLED OVER, CHECKED THE VEHICLE AND DID NOT FIND AN ISSUE. I WENT BACK ON THE ROAD AND THEN THE CHECK ENGINE LIGHT BEGAN FLASHING. I TOOK THE CAR INTO THE SHOP, WHERE IT WAS FOUND TO HAVE A BAD CATALYTIC CONVERTER, SPARK PLUGS, AND IGNITION COILS. THIS WAS NOT SOMETHING THAT HAPPENED OVER TIME. IT WAS VERY QUICK. I HAD THE PARTS REPLACED. 700 MILES LATER, ON 2/25/21, THE SAME EXACT THING HAPPENED. AGAIN, VERY CLOSE TO WRECKING AND CAUSING A VERY SERIOUS ACCIDENT. I TOOK THE CAR IN AGAIN, AND THEY WERE SHOCKED TO FIND THE CATALYTIC CONVERTER HAD MELTED. PER MECHANIC, IT IS DUE TO SERVICE BULLETIN 428 AND 429. PLEASE NOTE THAT THERE IS ONLY ONE AREA FOR ADDING SPEED, AND ONE AREA FOR DESCRIPTION OF ISSUE. THIS OCCURED WHILE DRIVING ON THE HIGHWAY, AND CONTINUED UNTIL THE CAR WAS TAKEN TO THE SHOP, TWICE, ON TWO DIFFERENT DATES.
