Electrical System Problems of Hyundai Elantra - part 1

No accident has occurred as of yet (for my case). Ongoing issues with Hyundai left brake bulb and center brake bulb burning out due to over-amperage. These two are on their own 10a circuit separate from the 5a circuit for the right brakelight bulb. It appears that these two bulbs are possibly receiving 15a and therefore burning out prematurely (3 months or less). I recently replaced these two bulbs at the same time, and now my battery is shorted. To keep my battery charged, I need to pull my 15a brake lamp fuse while the car is parked. This has now caused my abs light to come on, as that system relies on the signal from the 15a brake lamp circuit. I suspect that some 15a components (10a+5a) received 20a (15a+5a) and welded shut. I am still looking for it to trace it down, resources are limited and I'm intent on just buying the $35 diagnostics book. Hyundai dealership did not inform me that this fuse was pulled while I drove home from the shop yesterday, creating an unsafe condition. They quoted me $500 to replace a brake lamp relay and the abs (I'm assuming the whole abs, but maybe just the control module), I declined. My plan for now, as this car isn't driven much, is to trace it down and find the shorted component. From my research, this is clearly affecting many years of Hyundais and kias, not just my Elantra and not just my year. In fact, it's so common that there are facebook groups (such as this one [xxx] ) dedicated to helping owners remedy this defect. I think a recall service, and a full investigation of what is electrically wrong with these cars, and what the actual remedy should be, is necessary based on the amount of cars that could be impacted. Hyundai & kia technicians I am sure are intimately knowledgeable about this issue by now and us owners are on the hook, having only 80,000 miles of warranty on anything purchased used. Please reach out with any add'l questions. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle: 2022 Hyundai n line mileage at initial incident: ~17,000 miles components involved: engine and engine cooling; exhaust system / emissions; air bags (srs) I am submitting this complaint to document unresolved emissions system and supplemental restraint system (srs) safety concerns involving my 2022 Hyundai n line, as well as the manufacturer’s refusal to ensure proper diagnosis and corrective action following a documented dealer service error and subsequent warranty repair. At approximately 17,000 miles, a Hyundai-authorized dealership failed to reinstall an engine oil seal during a routine oil change. This error caused rapid engine oil loss at highway speed, activation of the oil warning system, and oil discharge onto the roadway. The incident is documented in Hyundai service records and is not disputed. Sudden oil-loss events of this nature are known to cause latent or progressive damage to internal engine components and federally regulated emissions systems, even when immediate engine failure does not occur. Despite proper maintenance after this incident, the vehicle subsequently set dtc p0420 (catalyst system efficiency below threshold – bank 1) at a mileage far below expected durability. Hyundai replaced the catalytic converter under warranty. I requested diagnostic data, inspection findings, and documentation supporting the repair, but the dealership refused to provide anything beyond a basic repair invoice. Immediately following this Hyundai-authorized warranty repair, the vehicle developed a new drivability defect, specifically hesitation during acceleration, which was not present prior to the catalytic converter replacement. This indicates a post-repair nonconformity and raises concern that emissions-related components may not have been fully repaired or that additional systems were affected during the warranty repair process. When I returned the vehicle for evaluation, the dealership stated that it would not diagnose the vehicle unless an acti.

This is the 7th time my vehicle has been parked and over night killed a battery. It’s been replaced 3 times and this battery lasted 8 months and now my vehicle is dead again. Also you can’t lock your vehicle if the battery is completely dead.

What component or system failed or malfunctioned, and is it available for inspection upon request? the car began stalling and started to become unresponsive while I was driving to work. While I was not 100% sure of what component was malfunctioning at the time, I suspected that it might be a timing chain problem because I had this same exact issue happen to to this car back in January 2025. I did not expect this issue to occur again because at the time of the previous problem, the dealership confirmed that issue was the timing chain and the vvt system, and replaced those components with new parts. How was your safety or the safety of others put at risk? the car started stalling and sputtering, then became unresponsive while I was driving. If I were in a high-traffic area, I'm not confident that I would have been able to accelerate, stop, or safely pull over to the side of the road without putting myself and/or someone else in harms way. Has the problem been reproduced or confirmed by a dealer or independent service center? yes, the car is currently at the dealership and they confirmed that the issue is the timing chain and the vvt system. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? yes, the car is currently at the dealership and they confirmed that the issue is the timing chain and the vvt system. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no, there were absolutely no warning lights, messages, or symptoms prior to the failure.

Driver side wheel baron was scrubbing together and brake fluid was leaking I lost speed can't go over 35 miles on the speedometer my airbag light is on on the dashboard, abs, the car with 2 lines and tire along with engine sign is on I look up for recall and it listed everything my 2012 Hyundai Elantra is doing I took it to Hyundai dealership in orlando florida on west colonial drive and 2 hours they called said it was ready they didn't do anything all the the same lights still on on the dashboard still leaking brake fluid and wheel baron and my brakes still scrubbing against each other speed reduction they claim they did the recall would not look at it again said they did it nothing changed I'm taking a risk of fire starting from brake fluid hitting the electrical box and wheel coming of and again all the lights on the dashboard is still on my name email address and everything is wrong on the paperwork except my phone number and I gave him my license with my information on it I'm asking the advisor how can he tell me that the work was done and recall doesn't necessary fix the problem but he knew my car remember everything that's impossible I told him why the lights still on and nothing changed also I asked him how do he know it's repaired he showed me no parts came off my car to say it was replaced nothing was replaced.

The car was being driven nomore than 1hr. It began to smoke under the hood. The abs emergency brake light, check engine then the eps lights were on. The vehicle was pulled over and stopped. Fire was then observed falling from under the car. The hood was then popped to see the engine mainly on the driver side was totally catching fire. Then it spread. The engine needle never showed over heated. The car took no more than 6 minutes to catch fire from the time it started smoking. It was very scary.

I didn't know the horn wasn't working. I was driving and a vehicle almost backed into me on the drivers door. I couldn't warn them that I was behind them I was fortunate to move before they backed into me. I haven't taken the car to the dealer. I searched on the internet to see if this was an isolated incident and I found hundreds of incidents of people reporting faulty horns on Hyundai vehicles. This should be a safety and a recall issue/.

While driving, pressing the accelerator pedal, the vehicle hesitated and stalled. No warning lights came on until after I attempted to turn the vehicle back on then the check engine light and low oil light were illuminated. My vehicle was towed to a local mechanic and I was informed that the engine was blown and to tow my car to a Hyundai dealership as I was still under the 10 year/100k mile warranty. After getting my car to Hyundai, I was told I had to get a combustion cleaning for $800 whether the cleaning worked or not before any warranty work could be completed. The cleaning did not work and it was then found that a pin was sheared off inside the engine. My engine was then replaced under warranty but I still had to pay for the cleaning. A second mechanic looked over my paperwork after getting my car back 2 months later and noted that the engine failure could have been diagnosed without the cleaning as the cleaning would not have affected where the pin was sheared off. My 2017 Elantra had 90,315 at the time of this incident.

Low pressure oil light did not come on until the oil drain plug had completely fallen out. Once the light came on, the vehicle was slowed and came to a stop on the side of the highway within 2 minutes. The car completely shut off as if the battery were dead. It had to be jumped in order to put the car into neutral for the tow truck. The safety issue is that the hwy we were traveling on is 70mph. At no time, did we receive a warning until it was almost too late. The car is currently at an auto repair shop as the engine is most likely catastrophic and due to the car having no power, they want to replace not only the engine but also the 12 volt battery and it's module. The low pressure oil warning should have come on way before the plug completely fell out and the battery should not be dead. The mechanics can't even fathom why an engine would fail quickly and drain the battery as well.

The vehicle has less than 2,000 miles on it being a 2024 model (hybrid limited) and on more than 2 occasions without warning the car will be dead while parked. No accessories left plugged in to cause drainage, no warning from the myhyundai bluelink app, and the dealers are completely clueless. The vehicle gets driven every day, and in order to "fix" the issue temporarily, I have to unlock the car manually using the physical key, and press the 12v reset button. That wont last long before the backup battery dies too.

The eps light started coming on intermittently back in Nov. 2025 and power steering became very difficult. I could get it to reset by turning off the car and turning steering wheel all the way to right and then left and then back to center and restart. The steering ability returned but the light eventually came back on. I had firestone look at this in Nov. And they recalibrated but advised if problem returned that I should contact dealer due to recall for 2010 Elantras for same issue. The light came back on this weekend. I note the recall is for Elantras manufactured through April 30, 2010. My car was manufactured June 20, 2010…. 6 weeks after the dates of the recalled models. Clearly this issue is affecting my car also. I plan to call the dealer and try to get them to look at it and see if they will repair under the recall… but I wanted to report this to you also since is affecting models outside the original recall dates.

We were heading back to ohio at mile marker 8 75n kentucky when we heard a boom. Then we saw smoke as my husband was pulling over. We jump out to get our child out of the car seat and at the same time a pickup truck pulls up with two guys. They yell that our cars on fire and began putting the fire out with a fire extinguisher. We had an oil change before we left ohio by valvoline. This area of the hwy isn't really patrolled and only has a volunteer fire department. A constable just happened to pass by us on the way to indiana.

My fuel pump comes up and my check engine light saying that it needs to be replaced when I fill up my car it automatically resets my mileage for aaa and trippy and it will tell me that I have no gas even though I just filled up or it will say I’m full when I know I’m empty so it’s not reliable. It comes and goes. And then for an electrical issue my car will randomly stop working and then like come back up and it was underneath the positive plug. There is a clip that someone had to extend because it was too short and causing electrical surges so it’s still a problem if I go over a bump it gets loose so that clip under the positive terminal I believe is loose and makes my car shut off in the middle of driving at once and then it came right back on.

Vehicle information: 2014 Hyundai Elantra se sedan, 4-cylinder, 6-speed automatic, fwd build location: USA-built version (montgomery, al - VIN '5np') ownership: second owner, purchased certified pre-owned (cpo) from the Hyundai of new port richey dealer (florida) in March 2016. Vehicle is owned outright. Mileage: 128,638 approximate date incident noticed: October 1, 2025 description of critical safety defect & warranty rejection I am reporting a failure of the clock spring assembly, which compromises critical safety features and poses an unreasonable risk, especially since this vehicle regularly transports passengers, including children. My VIN was rejected by the Hyundai txxa clock spring extended warranty validator despite exhibiting the exact failures covered by the campaign. Safety failures: airbag (srs): warning light is constantly illuminated; driver-side airbag is disabled and will not deploy, endangering the driver and front passenger. Horn: completely inoperable, eliminating a vital safety communication feature required to warn other drivers. Cruise control: buttons on the steering wheel are non-functional. These failures are caused by a broken electrical connection within the clock spring (which typically runs the airbag, horn, and cruise control circuits). I believe the denial is related to my vehicle being the USA-built version (VIN '5np'). I request that NHTSA investigate why this safety campaign arbitrarily excludes USA-built Elantras (but not korean-built) experiencing the identical failure, thereby placing an unreasonable repair cost burden on owners for a critical safety component.

Electric horn is not working horn issue technical service bulletin (TSB) 25-be-005h published on Hyundai tech info under Hyundaidealer. Com but it does not include 2019; it includes 2020 -2022 model years.

During the incident, there was an aggressive flow of smoke coming from behind the steering wheel within the dashboard indicating overheating and/or a fire. My vehicle was inspected by my local dealer, ed voyles Hyundai, who stated that their inspection found a burning left rear tail light assembly with fluid inside of it. No warning lamps or prompts appeared during the incident.

I've replaced the headlights 4 times and the daytime running lights 20 times! bought and installed 2 entire headlight assemblies. . . 5 days later right headlight blew out. Ive entered many complaints about this 1 vehicle and conveniently for Hyundai no recalls!!!! continuous oil level issue reported the very first time I put the car in the shop.

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.

I am reporting a recurring issue with my 2023 Hyundai Elantra where the low oil pressure warning light illuminates consistently during strong acceleration. This is accompanied by a distinct smoky odor from the vehicle. Based on my research into recall 23v-859, which addresses fire risks from a faulty electronic controller for the oil pump in the idle stop & go system, I believe my vehicle is experiencing a related or identical failure. The symptoms strongly suggest that the defective oil pump controller is malfunctioning under load, potentially leading to dangerous overheating and a short circuit.

My high beam lights have malfunctioned and no longer work. The light on the dash states that my headlights are on but they just flick on for one second and discontinue to work. I live in a rural area and can not see at all when leaving home in the early am hours or when returning home in the evening. I've had to stop on the side of the road at certain times, because I have no visibility. My car is approaching 6 years old with less than 70,000 miles and this is ridiculous. The dealership is charging over 2,000 dollars to fix this issue and I think this is highly unacceptable for a car of this age, especially when I bought the car brand new. I bought a brand new car to avoid issues such as this, but I have seemed to pay the price but not receive the safety that I have paid for. There are so many complaints online for this exact issue. I would highly appreciate if safety is held as a priority for this issue and you all place this as a recall ASAP.

The head lights will not go into high beam mode. When the high beams are turned on, they initiate and then flicker back and forth from on and off and will not remain on. This happens simultaneously with both lights. It appears to be a electrically issue with the high beam setting and the current not remaining constant. I have taken it to two different shops and they said it is a common with this car and to check for a recall because they have had others that had the same issued recalled. My VIN does not show a recall. This issue can also only be corrected by Hyundai. The places that I have taken it to said there is a special tool they have to use to even get to this component. I noticed this starting a few months ago and still has not corrected. I have not been able to use my high beams since Aug/sept.

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.

Got in the car to come home put the key in ignition turned it and battery was dead went to turn off and something popped and cloud of smoke started rolling out from underneath the hood once hood was up the smoke got stronger from behind the motor the battery we had to get the battery unplugged and pulled out to get the electricity out the vehicle because of the battery being dead but sill plugged up at the time it would continue smoking more and more and thicker thicker so my husband pulled the battery out immediately as doing so we both inhaled some smoke but we was more concerned about it catching on fire so we pulled through it . We are confused on how or why this happened nothing has broke or went wrong with my vehicle but serpentine belt brake and tire ware my mother had car inspected and service back in may nothing was said that there is or will be wrong with my car. We had no idea that there was anything wrong no warning lights no signs of any problems up to this incident.

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.

The headlights still cannot be used on high beam as the lights strobe when used. This was complaint was previously submitted with the same VIN#. This is dangerous for driver and others, including oncoming traffic. The local Hyundai dealer said it is would be $200+ for them to diagnostic and if they fixed it, the diagnostic fee would be credited toward the repair. How can this not be coved under a recall when it is clearly a safety issue and many mentions on line with others having the same problem? the VIN. # says there are no open recalls. How can I get this covered on my car that is the same model and year as others with the same problem. I see a couple service bulletin's and would like to know if any apply. Please respond with any help or suggestions on this matter as I need help from the NHTSA to get Hyundai to fix it. I am happy to send a video for proof. I look forward to your reply. Thank you very much!.

Vehicle issue description for NHTSA complaint: component/system failure: the engine of my 2013 Hyundai Elantra (VIN: [insert VIN]) completely failed at 51,000 miles. The alternator also failed and had to be replaced. There was a persistent smell of gasoline inside and outside the vehicle, creating a fire hazard. All components are available for inspection upon request. Safety risk: the engine failure left the vehicle completely inoperable. The gas smell created a serious fire hazard and caused me to experience health issues, requiring an er visit. The combination of engine malfunction, electrical issues, and fuel leaks posed a risk to my safety and the safety of others while driving. Confirmation by dealer / mechanic: independent mechanics inspected the vehicle and confirmed the engine failure and alternator issues. Multiple mechanics advised not to drive the car due to the fire hazard. The original selling dealer (larry h. Miller Toyota) inspected the car and acknowledged engine problems in writing on a business card. Inspection by manufacturer / others: Hyundai corporate has been notified, but they declined warranty coverage as the vehicle is a second-owner car and beyond the original warranty. The dealer has also been made aware of the engine failure. Warning lamps / symptoms: no warning lamps indicated imminent engine failure prior to the engine dying. The first symptoms were mechanical issues, gas smell, and eventual total engine failure. Alternator failure and repeated maintenance issues occurred within 8 months of purchase. Additional notes: vehicle purchased at 34,000 miles; engine failed at 51,000 miles. Independent repair receipts, er paperwork, are available to support the case.

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.
