Electrical System Problems of Hyundai Elantra - part 2

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.

Where the Hyundai place tell that I don't need drive that because recall on the light shower! on my car and how electric part in the car. I still a note the balance 14,700. The paying balance need be 9,900. Because the wiring and light show balance I would owe. 6,000.

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.

Both front headlamp assemblies broken hi beam mechanism. My cars headlights burn out every couple months and the bright lights will not work. I took to a Hyundai dealership on 03/28/2026 who told me it would be $5,333. 30 to fix. I have done nothing to cause this electrical problem on both headlamps and when searching the internet; this issue seems to be a big problem on this vehicle year. This is obviously an issue in manufacturing of the vehicle and should have the issue be a recall to fix. It is so dangerous not knowing when my lights will stop working again after replacement and not having the use of bright lights at night.

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.

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.

While operating my 2017 Hyundai Elantra under normal driving conditions at approximately 70,000 miles, the engine suffered a sudden, catastrophic loss of motive power and stalled completely while moving in active traffic without any prior warning. This severe stalling event occurred despite the vehicle being strictly and meticulously maintained according to all manufacturer guidelines and scheduled service intervals. Prior to the stall, the check engine light illuminated. A comprehensive diagnostic scan completed at an authorized Hyundai dealership confirmed active trouble codes p0014 (exhaust camshaft position timing over-advanced) and p0017 (crankshaft-camshaft position correlation error). The internal physical engine timing assembly and variable valve timing (vvt) components slipped out of synchronization, forcing an abrupt, automatic engine shutdown while navigating active roadways. This failure created an immediate, severe safety hazard and high collision risk due to the sudden loss of vehicle propulsion, power steering assist, and vacuum brake booster pressure, leaving me vulnerable in traffic. This structural timing deviation caused chronic engine misfires and forced raw, unburned fuel directly into the exhaust stream. This unburned fuel completely fouled and destroyed the primary oxygen (O2) sensor due to heavy carbon contamination and extreme thermal stress. The failed sensor and incorrect valve timing totally disrupted the electronic control unit's air-fuel management, inducing the unpredictable stalling hazard and causing an immediate, automatic state emissions/smog inspection failure. Repairing this underlying manufacturing and metallurgical defect at the official Hyundai dealership required an extensive mechanical teardown and replacement of the timing components, costing approximately $2,500 out of pocket. This exact failure pattern, cascading O2 sensor damage, and diagnostic trouble codes match hundreds of existing complaints with NHTSA.

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.
