Vehicle Speed Control Problems of Hyundai Accent - part 1

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!!.

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.

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.

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.

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.

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 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.

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.

The contact owns a 2013 Hyundai Accent. The contact stated that while operating the vehicle the vehicle had experienced unintended acceleration on several occasions. After parking the vehicle in the garage and switching to the park position the vehicle had experienced unintended acceleration and crashed into the back wall of the garage. The cause of the failure was not determined. No injuries were reported. The manufacturer was notified of the failure but no assistance was offered. The vehicle was examined by an independent mechanic but the no cause no problem was found. The failure mileage was 2,154.

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.

Electrical issues horn doesnt work nor does the speedometer . .

Cam shaft split system emission failure . Lighter socket not working. Valvolibe oil change 7/16/21 mail recall. Recieved 7/1721 vehichle loud sound. . Acceleration not speeding . Car. Not drivable.

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.

While driving on the interstate, car decelerated and would not go past 5 mph. Had to get it towed. Throttle body replaced and now needs the the catalyt converter replaced in which I do not have the funds. There is an ongoing "ticking/clicking" sound in the engine, check engine light is currently on. While driving and coming to a red light, the car engine revved and the car started accelerating even though my foot was firmly on the brake. Car made a jerking move so I threw the gear into n and then park to stop the revving. Car is currently parked.

I'm not sure.

I dont no why but my engine will randomly stall out even in the middle of making a. Left or a right-hand turn and it's scary when I a. M. At an intersection intersection and I doll out then I have to shut my car off completely turn it back on and pump the gas. Till it starts . Few days later my warning lights came on the meters and lights shot up quick and. Then the car shut down I was so freaked out my husband took it to the dealer ship they stated it was. A tire valve sensor they claimed to have checked all the fluids which I no was not the oil was burnt when I got out and checked old oil they want me to pay before they can repair but tire valve is not the #1 because I had another shop change. Out the stem these random occurrences happen today and warning lights still on. I read these sensor àre covered upto 100,000 miles.

Wow entering the highway my car stalled out in the middle of traffic the never cut out just will not drive more than about 5 miles an hour even with putting my foot all the way down on the pedal turn it off for 30 minutes started back up started driving start out again almost causing me to wreck multiple times no warning lights or anything popped up I still have no lights on my dash and it is still not drivable had to get it towed by aaa I don't understand how did you record that is 3 years old is having this issue with no warning I'm very blessed that my children weren't in the car considering the diesels coming behind me why are the highways with this happening all of the sudden the car does not shut down it just loses power far as driving accelerating.

Not exactly sure when but my �passenger airbag off� light started to randomly appear and never turns off despite there being a passenger. Also my back seats would not latch closed, creating an unsafe riding time for a child in a booster seat. Which is a huge concern because I frequently provide rides for two young children my air conditioning unit becomes so hot that my feet are literally burning me. I end up taking my socks and shoes off due to how hot it gets. The motor for the engine is incredibly loud despite the small amount of miles. I have issues with accelerating from stop.

Most days of the week, upon start up, I get 3 lights that come on and most of the time do not go off, the 3 lights are: brake light, abs light, and traction control. When then car is in motion, the speedometer doesn't move and my gas gauge will change numbers while in motion. In motion, I feel like the brakes are touchy but I don't feel the brakes gripping like the lights shown and don't feel any difference in speed or gear switching.

I have previously reported this. My 2012 Hyundai Accent with automatic transmission often surges. On the highway, it will continue at same speed or even accelerate when I lift my foot. Stopped in traffic, it will lurch forward when the car ahead of me moves and I lift my foot. When parking, it will red-line when I shift to neutral or park. This does not happen all the time, but happens throughout certain trips, from when I begin to drive, until I exit the car. I have been to the dealer for evaluation, they say there are no codes, so it didn't happen. Apparently it did not occur during their test drive. This is a chronic problem and has been going on for a couple of months. When car tries to run away, I turn off the key. Will that remedy continue to work?.

Driving on the highway I heard a knocking in the engine. The check engine light came on. I took the vehicle to get the light checked for a code and was told the knock sensor needed replacing. Took the car to the dealer I purchased it from and dealer said there was no code and no history of a code so they could do nothing about it after I told them how to replicate the knocking. Dealer released the car. Two days later while driving on the highway the light came back on and the engine continued knocking. I took it straight to the dealer again and they were able to replicate the issue and find a code. The dealer contacted the manufacturer about the code and the manufacturer recommended applying a patch to the knock sensor and, according to the dealer "see what happens". The dealer performed the patch and released the vehicle to me. The very next day I was driving home after work on the highway and the odometer went from 3000rpm's to 0. While I could try to engage the accelerator and could hear the engine rev no rpms registered. The vehicle went into an idle state and would not react. Causing many near accidents I was able to get the car to the shoulder before it became stationary. Attempted to restart car a dozen times and the rpm's would not register still. Car has now been with the dealer who has not been able to replicate the issue and has not reached out to the manufacturer. The cause and effect of an issue happening after applying a computer patch is not being investigated nor discussed with the manufacturer.

I am very unsatisfied with the fact that I have to get my oil changed 1 every month, due to burning oil as well as hard ride. My car will not pass inspection after 2024, due to emissions, I paid $600 to get a passed sticker and sick of dumping money into this vehicle. There have been so many recalls on this car. What is Hyundai willing to do ? I’ve purchased this vehicle in 2013 from brad benson Hyundai on route 1. Please get my car running normal again. I have most of my receipts for all repairs and maintenance. I have 150,000 miles on the vehicle. Please help valvoline informed me of engine recall for my vehicle.

The dash lights; brake, abs, and traction control lights come on. The speedometer also does not work while driving. The gas gauge is going up and down and not showing the correct gas. The electrical appears to be malfunctioning, but the dealer has yet to recreate the issue. This has happened twice in a span of a week. Videos were taken both times it occurred on 5/14/19 and 5/20/19, but are too large to upload.

Burns off 1/2 qt of oil every 1500 miles. Po326 (knock sensor) trouble code on chilli mornings. P050a (cold start) trouble code while driving.

Once I am driving on the highway the car seems to loose power almost like if the car wants to shut off the rmp goes low then the check engine light has turned on. I have taken it for its service on time and no issues but the good year rep told me the error code they received was p0326 which is the knock sensor and now the engine light went away but it has happened twice so far within the last two months.

I was in an accident on March 12 2018 a tractor trailer sidewiped the LS of my car and destroyed the entire side . The car might be totaled. No airbags went off at all! he came into my lane at a good speed and a full load. I am lucky to be alive. I have had other problems with this car only to be ignored by the dealer. I paid cash for the car at the end of 2015 and now I have nothing. Besides being hurt.

When driving, especially in colder temperatures, when accelerating and braking, the brakes feel like there is something not letting the pedal go down when you push them. Ever since I noticed that happen, the acceleration and speed stays at a higher speed when driving. I have to be very careful when accelerating behind another vehicle so it doesn't go too fast and hit the vehicle in front of me. I have to use my brakes a lot more right after accelerating.

After starting the engine and tapping on the accelerator, the car will accelerate on it's own and rev up to 1,500-2000 rpm without pressing on the accelerator. Even when braking. Returning the car to neutral causes the engine to rev up to or beyond 2,000 rpm until the vehicle has been turned off. This incident first occurred in April 2016. I was told there was an issue with the sensors by the Hyundai dealership. The issue resurfaced again in January 2017. This time they told me it was due to a carbon buildup in the fuel system. Now it's doing it again. I have seen many other reports of this happening to hyndai's on the internet. This is a huge safety issue.

I've been to 2 Hyundai dealerships,. . . They both told me they can find anything they cant duplicate the problem. It makes me mad because I take off work to go get my car taken care of, but to them nothing is wrong. My car lags at times. When I stop at a light or stop sign, its hard to go,. . It stalls I have to floor it at times to even get it to 25 0r 30. I know my car doesn't have much horsepower but shouldn't have to floor it to even get it to 25. This is a accident waiting to happen. Its like Hyundai wants you on the side of the road or an accident before they believe you. I've see other complaints about the same thing on car compliant. I guess me and those other people are crazy. I'm thinking about getting a lawyer if this isn't taken care if soon.

I purchase a 2007 Accent Hyundai and while driving it stalls very dangerous. I purchased this car for my son as his first car. While the car is in motion it just stops running while the car is in motion. Wont start up for 20 min or an hour just to do it again. You can be on the highway or just up the road very dangerous. Car just stops for no reason why wasn't this car recalled.

The contact owns a 2012 Hyundai Accent. The contact stated that while at a parking lot, the vehicle began to accelerate independently without any warning. The failure recurred several times. The vehicle was towed to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 54,000.

I've had my 2016 Hyundai Accent 5-door since February 2016. On several occasions, I have noticed two issues. The first is that coming to a complete stop, when pressing on the brake pedal it feels like something is hitting the ground beneath my foot on the underside. Dealership found nothing because they couldn't duplicate it. The second is when at a stop sign, etc. , and you start trying to increase the speed, the engine has a hard time gaining speed as quickly as it should. I have to press the acelerator to the floor board to get moving. I know that my vehicle isn't one with a huge engine but still it shouldn't struggle to gain speed every single time! I'm not very happy about this and will be taking it back to check both the brakes and engine.

Takata recall: I had took my car into the dealership multiple times while it was under warranty because it gets stuck when shifting gears and won't pick up the power when accelerating. While the on the highway it drives horrible and the steering is unpredictable. Each time that I took it into the hyunadai dealership they can't figure out what wrong with it. While it was still under warranty I did take it to other places to see what they would say and they all noticed the issue and stated that it appears that it's with the transmission. I did contact hyuandai directly and they refused to fix the problem and now the car is out of warranty and I am screwed!.

The contact owns a 2012 Hyundai Accent. While operating the vehicle, the vehicle accelerated on its own. While parked, the vehicle would rev to approximately 5,000-6,000 rpms even when the brake pedal was depressed or when the vehicle was in another gear. The only way to stop the failure was to remove the key from the ignition. The failure occurred without warning. The vehicle was taken to the dealer where it was diagnosed that the throttle body needed to be cleaned. The vehicle was repaired; however, the failure recurred. The manufacturer was not notified of the failure. The failure mileage was approximately 61,000.

Always needed oil.

My car is a manual transmission and when press the clutch the rpm go up to 4,000 rpm and I think that is the acceleration pedal may stay stock because doesn't do it all the time. I used my car everyday to go to work I really treat the car good only have a 25. 000 miles on it.
