The contact owns a 2020 Hyundai Elantra. The contact stated that while his son was driving at an undisclosed speed, the lane assist safety feature failed to function as intended. The messages “forward collision avoidance”, and “lane assist camera disabled” were displayed. The vehicle was taken to a local dealer, where it was diagnosed, and determined that the forward collision avoidance and lane assist camera needed to be replaced. The vehicle was not repaired because the warranty was invalid. The manufacturer was made aware of the failure. The failure mileage was approximately 110,000.

The horn never worked since I bought it in August 2023, I’ve been in a countless near accident situations where I was rendered helpless. I’ve had several instances where I get locked out of my car because the vehicle would not read the key. I tried fix the issue because I assumed it was a dead car or key battery but the same problems kept happening shortly after. I became aware of the issue with the horn not working, when I recently purchased the vehicle. I tried to contact the alm dealership salesman to report the issue and they told me he had recently quit. They mentioned bringing it back to the shop but it wasn’t guaranteed that the issue would be fixed.

The car now shows a warning "check forward safety system" and cruise control, understandably does not work. I have not had any collisions or accidents for this to occur. There seems to be no recall from Hyundai, however, this appears to be a safety issue that needs to be addressed by Hyundai.

The engine bay of my car caught fire due to the abs pump and module not turning off. I bought a part but never opened the box because I received a piece of mail stating the recall of that exact issue that they would replace all parts damaged. Which they didn't just installed their relay after Hyundai recall 188 was completed, my abs pump failed. I believe it was caused by continuous power being applied post-shutdown — the exact defect the recall was meant to fix. The dealer performed an inspection but misrepresented the results and refuses to replace the damaged component under recall. This abs pump failure is a direct result of the original recall condition — or a failed installation of the relay fix — which continued to keep power applied to the pump while the vehicle was off. This is the exact scenario the recall was intended to prevent. If the failure is caused by that condition, Hyundai is still responsible under recall. The facility which did the recall falsely recorded the mileage on my vehicle as to void any "warranty" associated with the recall as the car hasn't been driven since the module was replaced. I also instructed the diagnosis team of wesley chapel Hyundai to keep my battery unplugged due to the parasitical drain in order to protect the battery from being dead celled and now I have to replace the battery as well. They also illegally opened a mailed box I had in my car with a part I bought prior to the recall being mailed out which I never took out of the box nor did I open the box and it was fully sealed which is a federal crime. I opened a case in which Hyundai denied helping with this faulty service and are refusing to provide me documents case no. 41355389.

I am unable to use the high beams. Low beams are very hard to see with making risky when driving at night. No warning lights.

When you accelerate & let off the gas pedal, the vehicle still accelerated for 2 seconds after you release the gas pedal. It is like there is a delay with drive by wire signal. This situation can cause rear end collisions & hard panic braking. Please recall this situation to prevent higher insurance cost & increased accidents!.

Both headlights bulbs needed to be replaced several times. Passenger replacement bulb 3 times. Drivers side twice. I have sent Hyundai several emails and have not heard back from them. Case # [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle has experienced ongoing powertrain and electrical malfunctions over several months. The most common symptoms include being stuck in 4th gear (limp mode), complete loss of rpm and speedometer readings, and illumination of the check engine and esc lights. Most recently, while traveling at approximately 10 mph, the vehicle experienced a sudden loss of both acceleration and braking. The brake pedal became stiff and unresponsive, and the car had to coast to a stop without driver control. This posed a serious safety risk to myself and nearby traffic. These issues have persisted across multiple service visits to ricart Hyundai in groveport, ohio. That dealership has replaced the crankshaft position sensor three times, the powertrain control module (pcm), and the battery, but the underlying problems remain unresolved. A technician at the dealership was able to reproduce the stalling event during a test drive. Despite that, the dealership has refused to proceed with further diagnostics unless I pay for an oil change, even though previous inspections by their own staff found no visible leaks and confirmed the oil level was sufficient at the time. They have also revoked complimentary access to a loaner vehicle despite the unresolved and unsafe condition of the car. The vehicle remains available for inspection. The problem has been confirmed by a dealership, has occurred repeatedly, and continues to pose a safety concern. Warning lights and gauge failures typically appear when the issue occurs.

This seems to be a very common and serious issue with Hyundai vehicles. 2013 Hyundai elanta, believed to be a frequent crankshaft position sensor issue. When driving the car, they vehicle will feel that it is losing power. When coming to a stop the engine will idle so low that it feels like it will stall or it does stall. The tachometer registered zero rpm's, even when accellearting. Attempting to accelerate up any incline and the car can not provide enough power. Sometimes the car will crank up, other times it will require time to restart. The car has stalled and low power idling multiple times, but it did happen in the middle of a 4 way intersection twice, and when the issue is present. Although we've been fortunate, no accidents have occurred, it is very unsafe for the owner and other drivers. This occurance has happended several times over the past year. Two times it was immediatley brought into the dealer service, the second time it did stall with the service member there. Both times they were unable to diagnose the problem and stated no error codes were reported. You have already issued a recall for this same issue with a different model. Oct. 13, 2017 – Hyundai motor America has recalled more than 400 vehicles potentially equipped with defective crankshaft assemblies, according to documentation submitted to the national transportation safety administration. There are so many others that have reported this same issue and have been corrected with the replacement of the crankshaft position sensor. . Read more...

Headlight housing mechanism for high beam and low beam lights do not allow headlights to stay on high beam. Will not pass massachusetts motor vehicle safety inspection.

My auto has a problem with the brake light on the drivers side not working at some times. The issue seems to happen almost every 6 months or so. The first time it stopped working, I took my auto to the dealership where I purchased it from costing me about $65. 00, the second time 6 months later the brake light went out again. The bulb was replaced by the dealership at no charge, I was told that the bulb was put in wrong. The brake light is now out again. I noticed that it may come on but when I press the brake pedal and release the emergency brake, it goes out and stays out until I shut the auto off for a long period of time. Often it will be on when I'm driving and then it goes out.

On [xxx] and [xxx], while driving at approximately 50 mph, my vehicle experienced a sudden and complete loss of power, presenting an immediate safety hazard. The incident unfolded as follows: without warning, the car emitted an alarming sound from the cabin. Simultaneously, a message appeared on the dashboard stating "check hybrid system" and instructing me to "pull over safely. " this was the first and only warning; there were no prior indications or symptoms of any problem before this sudden failure. Immediately upon this warning, the vehicle experienced a total loss of power. The component that failed appears to be the hybrid system itself, leading to a complete electrical system shutdown. The vehicle is currently available for inspection upon request. After safely pulling over and turning off the car, all electrical functions ceased. This included essential safety features such as hazard lights, rendering the vehicle completely inoperable and "electrically dead. " my safety and the safety of other motorists were severely put at risk due to the sudden and complete loss of propulsion and all electrical systems (including safety lights) while the vehicle was in motion. This left the vehicle vulnerable and invisible to other traffic, particularly concerning if this occurred on a highway or at night, as it creates a high risk for rear-end collisions or other accidents. I have personal video documentation of this incident, which clearly shows the dashboard warnings and the vehicle's subsequent electrical failure. I am prepared to share this video upon request. Following this alarming event, I took my vehicle to the wolfchase dealership in memphis on may 16 2025. The problem has not been reproduced or confirmed by the dealership. Despite their inspection, the dealership claimed they could not find any issue, stating that "no system of record is recording such code in the vehicle. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I started to see the oil light on the dashboard and I heard a hard sound from the engine so that I changed the oil then after a couple days I saw the light again on with a little bit high temperature, so stooped by a gas station and I added some more oil after I shut the car off and waited to cool the engine down and I started the car, the oil light was gone and the engine sound was smoother then I started to get the same issue every couple days and I used to fix it the same way and I've had the same experience with my previous car which was the same brand but different year band model which I found a recall on the engine after it blown and the agency or the manufacturer changed the engine for free for that car and the current car has the same issues and it's included in the year range for that recall which from 2012 to 2019, that scares me because I drive everyday for rideshare and that can be dangerous for me and my clients who ride with me, also some of them stopped calling me for rides once they knew about that issue. And today I noticed the car beep which I used to hear when I lock the car with the remote has stopped too.

The horn has failed four times on my vehicle, and I have owned and maintained it since November 2022. While Hyundai has replaced it under warranty at no charge, I foresee this being a continuing issue.

My vehicle was towed to manly Hyundai in santa rosa CA June 18,2025. The vehicle when driving steered all over the lane then locked up on me almost causing a crash. The dealership says it’s the electrical column assembly. My vehicle is a 2017 Hyundai Elantra but don’t see any recall on it and I am being charged $3400. 00. The red steering wheel light went on . I’m looking for a recall on this vehicle seems many others have had the same issue. I do not have any receipts yet since it was towed and parts are being ordered and work will start this week. As soon as I have paperwork I can forward it to you. Thanks for your help in advance. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

This is a repeat incident. While driving, the speedometer stops working, tachometer, all of the collision warning systems start going through a self test, the check engine light comes on, and most concerning is the power steering. It becomes heavy, as if it is working at half power. The dealer kept the car for over a week recently, and they said that they were unable to duplicate the issue. It happened again while I was on a road trip , and I stopped by five star Hyundai in albany GA. The service advisor was aware of similar issues have occurred on Hyundai's, but that they were too busy to look at it. She wouldn't even come out of the building to look at the car and wasn't interested in looking at my video. I tried to upload video to this form, but was unable to do so.

Rear camera suddenly stopped working while reversing. Happened approximately at 19,000 miles. Don't know the cause but seems like a safety issue since rear view cameras are federally mandated. The usual camera view is now replaced by green error screen that says "no signal received. Please try again later".

The issue involves the hybrid electric powertrain or electrical control system in my 2023 Hyundai Elantra limited hybrid. The vehicle has shut off multiple times while driving, with complete loss of power and propulsion. This poses a serious safety risk, as it happens without warning in the middle of the road. Restarting the car requires shifting into park and trying multiple times to turn it off, but the vacuole turns back on the first try. I have experienced this issue several times, including twice during a 300-mile highway trip. After each shutdown, the dashboard displays multiple warning lights, including the check engine light, battery light, oil pressure light, and hybrid system warning (orange car icon). I took a photo immediately after the most recent failure to document these warnings. The vehicle has been inspected three times by two different Hyundai dealerships. Both confirmed the vehicle is under warranty but have not repaired or diagnosed the issue, citing that they cannot replicate it. They have driven it ~200 miles without success. However, they have not pulled ecu data or freeze-frame codes, even though warning lights were active at the time of failure. There are no symptoms or warning messages before the failure — the vehicle shuts off suddenly. The car is available for inspection, and I am in the process of opening a formal case with Hyundai. This is a significant and recurring safety hazard that must be addressed. This issue has an occurred a various speeds including during acceleration and braking. The picture attached is the dashboard after the I indent has occurred and have shifted to park after stopping to try and restart the car to get out of the middle of the road.

Constant misfire issue causes vehicle fo completely bog down while driving. .

I own a 2010 Hyundai Elantra that has experienced a sudden loss of power steering assist on multiple occasions. When this happens, the steering wheel becomes very difficult to turn, especially when maneuvering at low speeds or parking. The eps light comes on and stays illuminated. This creates a serious safety hazard, particularly when driving with children or in traffic. I am aware of Hyundai recall 127 (NHTSA campaign 15v100000), which addresses the same issue, but my VIN is not included. I am requesting that Hyundai investigate and provide the same repair remedy for vehicles outside the initial recall VIN range that are experiencing identical failures.

Cluster screen was black. Lasted for 30 minutes the initial time. Happened again, lasted for 3 days before turning back on. No turn signal sound when using turn signals. No speedometer or any of the main screen shows. No blind spot indicator lights or sounds either. No engine lights or any other lights visible before this occures. Safety was absolutely at risk. Couldn't even tell the speed I was going .

1- horn. 2- was not able to warn other driver of improper lane change. Was not able to warn driver backing out of parking space almost causing accident. 3- yes, by dealer. 4- yes, by dealer. 5-no warning. Horn just stops working. Appeared at first 5k miles. Note: this is a common complaint in Hyundai forums for many years.

Abs and traction control lights on as well as e brake light this is all after I had recall work that was supposed to fix this problem but only made it worse I am dealing with Hyundai but I don’t see a solution for this problem my car is inoperable and very unsafe it is my main source of transportation to and from my place of work and without this vehicle I am at a great loss I have lost brakes completely at times and am mentally and physically unable to drive this car it’s that bad financially strapped from sinking money into this problem only to find there’s a recall but the recall work didn’t fix the problem and Hyundai knows it won’t fix the problem.

Driving on interstate at 70mph. Multiple, five or six, warnings pop up in rapid succession mostly dealing with the safety features such as distance to car in front, adaptive speed control, lane keeping. The last one was hybrid system - safely stop. The car then immediately lost all acceleration power leaving us coasting. This all happened within a few seconds. Terrifying. Luckily we had space to get over quickly. 30 miles sooner we would have been in downtown jacksonville with no place to maneuver. Extremely dangerous. A few seconds warning then nothing. Turned the vehicle off as soon as we stopped and car was completely dead, no electrical power to anything, including flashers. Not sure how you can’t have flashers on a hybrid. Basically no warning to no power at highway speeds and then no flashers. Something is seriously wrong with this.

A significant class action settlement, known as the Hyundai engine ii class action settlement, was established to address allegations of engine defects in various Hyundai models. This settlement includes vehicles equipped with the nu 2. 0-liter gdi engine, such as the 2014–2020 Elantra gt. The lawsuit claimed that these engines could suffer from issues like engine seizure, stalling, and potential engine fires. My vehicles engine is the engine listed above and has been experiencing those exact problems. My engine has been stalling and making a knocking noise. A professional mechanic evaluated my vehicle and diagnosed it with first stage engine failure. Engine failure of any kind while driving is extremely dangerous and could lead to sudden stopping on a highway, collision, and result in the loss of life of both the driver and other drivers sharing the road. In addition to the engine ii settlement, there was a separate class action settlement related to the theta ii engines, which are also found in some Hyundai vehicles. This settlement addressed allegations of engine defects that could lead to engine failure. Hyundai motors is refusing to honor their warranty coverage for my vehicle. They claim their refusal is due to my vehicle having a rebuilt title, however, nowhere on their website or per any other guidelines do they explicitly deny coverage for rebuilt title vehicles. They clearly state that only salvage titles and 'total loss' vehicles will not receive any warranty assistance, which my vehicle was never considered a total loss. Additionally, when speaking to a bob howard Hyundai representative, they informed me that they have previously honored warranties for people in my exact situation. The engine in my 2014 Hyundai Elantra gt is the original engine with a matching VIN number and the engine failure is strictly due to the malfunction of said part produced by Hyundai motors. I have maintained and preformed regular maintenance on this vehicle with receipts.

While driving in a parking lot. The car wouldn't accelerate. Kept pressing on the gas pedal but the car wouldn't move. After about 5 seconds the car shut down. I had to place the car on p then press the start button, pressed the brake pedal and then the start button again and the car turned back on.

My car started hesitating when shifting gears in Smart and normal mode smelled like something was burning. Car only drives in sport mode, shifts hard, engine lags, and the check engine light has not come on. This is the second incident with this car. The first time I lost all power to the car and the entire electrical system shut down, when it was towed to the dealership they said nothing was wrong with it. I keep up on all the maintenance.

The horn stopped working in our 2024 Elantra. This is a widespread issue (see NHTSA complaints and reddit posts). I called ahead to verify with the san leandro dealership that parts were in stock to perform this repair under warranty (prior to scheduling appointment). We arrived and were told that parts were actually not available (after a 3-hour diagnostic). What changed? Hyundai issued a TSB (technical service bulletin) informing dealerships of how this issue is to be repaired (designating a specific part number, while excluding otherwise qualified Hyundai parts). Without TSB, the dealership could have performed this repair under warranty with the in-stock parts. The dealership could still perform the repair, but Hyundai would not reimburse them under warranty. With a[xxx] wife, I was unable to wait and return later for the warranty to cover the repair. I paid $429 to the dealership for the repair to be done with in-stock parts. I left the dealership with a genuine & working Hyundai horn, but it was not covered by Hyundai’s warranty. Hyundai has refused to reimburse us. Two key takeaways: 1 - Hyundai is denying there is a widespread issue while secretly telling dealerships how to address it. The unpublished TSB demonstrates that Hyundai is aware of a widespread safety issue, and is failing to issue a recall. The majority of nhsta complaints for this vehicle reference horn failure. This is a safety issue. I was involved in an accident where I could not warn another driver before the collision. 2 - the TSB is a mechanism by which Hyundai is refusing to perform repairs that should be covered by warranty. This is a violation of Hyundai’s stated commitment to customers that is not stated even in the fine print of the warranty.

No incident - high beams inop.

The contact owns a 2013 Hyundai Elantra. The contact stated that while attempting to start the vehicle, there were several warning lights illuminated. The contact pressed start/stop button several times before the vehicle started. The contact stated that the instrument cluster went black, and the radio and clock were inoperable. The contact stated that on other occasions the key fob failed to unlock the vehicle. The contact had the vehicle towed to a dealer to be diagnosed. The vehicle was diagnosed; however, the dealer was unable to determine the cause of the failure. The vehicle was not repaired, and the failure reoccurred several times. The contact had the vehicle towed back to the same dealer. The dealer diagnosed the vehicle and determined that the 12-volt battery needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The manufacturer was not informed of the failure. The failure mileage was approximately 99,000.

The 2022 Hyundai Elantra hybrid blue intermittently displays check hybrid system stop safety in instrument cluster screen, which stops the car from driving in either Smart or normal. This happens on the roads and highways. This is very unsafe because at high speed when this happens you could easily get rear-ended because the car drops its speed and cannot accelerate any faster than 30 miles per hour and then it degrades to 20 miles per hour until I can find a safe place to park and turn off the car to do the reset to be able to drive again. This happens because the 12-volt lithium battery is not providing an acceptable amount of charge to the hybrid battery. This was also confirmed when I took the battery to get tested and it failed the test. The next part that is unsafe, is replacing the low 12-volt lithium battery, because it is connected to a high voltage 240-volt lithium-ion polymer battery; there a normal person cannot simply replace it. You have to know electronics to make sure you do not get electrocuted. In addition, it takes hours to take out the battery and then it’s hard to find to purchase. I feel Hyundai makes this process difficult as after spending hours to screw it out, you cannot locate the item anywhere. When I spoke to the Hyundai parts person, they could not locate it until I actually brought in the battery. The 12-volt lithium battery was nonrefundable and cost twice as much ($545. 92) as I saw online, as low as $282 once I obtain the part number from the Hyundai order, which again is nonrefundable. I feel they make sure this cannot be found to force you to come to them to buy the battery, because all the labels or characters on the battery were not able to locatable. This was proven by me emailing the battery images to the parts person who was trying to find it, but could not until I bring in the actual battery. I was also told it is a special order and that they do not keep them onsite and have to be ordered and wait 7 to 10 days(pdf attach).
