2017 HYUNDAI ELANTRA Electrical System Problems

There was a recall Electronic Power Steering (EPS) motor connector that was being done for 2017 hyundai elantras and my car is affected by it. Hyundai is saying my car is not affected by the recall that they put out for this 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...

to whoever it is that can help, I am reaching out to submit a formal complaint regarding my 2017 Hyundai Elantra due to ongoing mechanical and structural issues that began very shortly after I purchased the vehicle, which have progressively worsened. I made the purchase in January 2024 for approximately $13,000 with 60,000 miles. The vehicle now currently has approximately 108,000 miles. Since purchasing the car, I have experienced consistent time consuming and serious issues that I believe indicate defects in manufacturing or design. First, the thermostat had failed during the first winter season I owned the Elantra, despite replacement the vehicle’s heating system still does not function properly. I’m not a fan of the cold. Also, the engine burns oil at an extreme rate. I am required to add oil literally every 2–3 days to prevent the engine from running dry, which presents a serious risk of engine failure...

Both Driver and Passenger doors do not open from the outside.

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...

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.

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)

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

Hi the smart junction box on this vehicle is acting up. When riding in free way all doors locked open automatically and then the headlights just went off, and all the 4 blinkers stopped working creating hazard to all people in the freeway including mine . Mechanic has quoted me 2k to fix the issue and replace the Smart junction box . Please provide me fairness in this matter

Power windows stop working, car cuts off, heated seats stop working intermittently

Check engine light on Transmission sensor is wack Car slugs and knocks. This car also has the white paint defect! This is my first and last Hyundai, go to accelerate onto interstate but can barely get the car to go past 30mph

My steering wheel locks up on me and the my check engine light flashes on as it does. I also have a steering wheel light with an explanation point beside it flashes when and before my steering wheel locks up! I can be sitting at a red light and my steering wheel locks up on me. My traction control light is also on and will not turn off. It turned on when my steering wheel locked up and my steering wheel icon came on.

When car is unlocked the drivers door will not open until you pull 3 times. Now the passenger door will not open at all from the outside. You have to open door inside car and push door open.

The car doors on my Hyundai Elantra often have jammed frequently jammed the front door was repaired when A few weeks later the back driver side door also jammed and could not be opened from the outside Unless you pushed in and pulled out. Then it finally jammed altogether and would not open . If there were an incident and someone needed to get into the car to get my child out they would be unable to.

Without any warning lamps coming on, the vehicle car stalled while driving on the highway. It randomly stalls constantly when turning corners, especially on left turns (odd?). The scariest thing that happened was it got stuck on the speed limit of 55-60 miles per hour and I couldn't brake or accelerate. This put my kids, other drivers, and my life at risk. On Father’s Day, while my husband was out with the kids the vehicle tried to accelerate on its own when he was at a stop. It happened multiple times as he tried to make it home. Then when he was in stop and go traffic, it got difficult for him to brake. The brakes started failing. What more can I say?

Since January 2024 I have had issues with my car starting due to low oil. I just had an oil change so I knew something was wrong. The repair shop stated there were no leaks and put more oil in and said that sometimes the car will not start if there is not enough oil. February 2024 and the car wont start again. Filled it with oil and took it to the shop again. They stated that the engine is eating the oil and to take it to the dealer for a test. Since then the car has turned off multiple time both while idling and while on the freeway. When you hit the gas it will not accelerate either. In the past I was able to turn the car off and back on again and it would work just fine but now it seems more frequent. Also, while driving...

Rear Passenger door does not open.

For a little over a year now, my back doors do not open on my Hyundai Elantra. The child lock is not on. Also in the past year, my passenger and driver door do not open. I have to go back and forth on the handle 20-30 times before my door opens. I have changed the battery in the key fob and I have tried unlocking my doors with the actual key with no success. Sometimes if they do not open I have to go through my sunroof. This is such a safety issue it’s insane. I’ve called Hyundai dealerships but they said they will need to keep it for 2 weeks. I do not have any other vehicle to just leave it there for that long. Please help.

the door handle doesn’t open from the outside, causing you to open from the inside

My two back doors will not open they just opening

The car randomly dies on de-acceleration. It gives no warning and I have seen online this is a known issue with this year/model. I have 55,000 miles on it, it's been regularly serviced. When I got to slow down then start to accelerate it shuts off. I've nearly been hit multiple times going to merge from a stop. It's very dangerous. I've replaced all 4 spark plugs, all 4 ignition coils, air filter, cabin filter, oil filter, PCV valve and I've only owned it 6 months. No engine light comes on and no reader is picking up any codes. I'm at a loss as to what causes this.

Car will lose power and quit suddenly on the highway with no warning lights. It has happened twice in the last month on a trip both times. Light’s low beam randomly won’t turn on either but high beams work. Had it into the Hyundai dealership and another mechanic shop but cannot find the problem.

My car has been dying while on the road when I'm slowing down. I have spent $2,700 to get this issue fixed, and after replacing everything the computer said was wrong, the auto shop has determined that the issue is, in fact, the computer itself. There is nothing left to fix, but the car still will completely shut down while driving. Not safe at all, especially since I live in a high traffic area. There are no warning signs before the car shuts down, but lights do show up on the dash when it has shut down. The check engine light, oil light, and battery light come on.

When driving about a month ago my car all the sudden started making a clinking noise not so much knocking in the engine or near the engine. And then it died all the sudden at a red light out of no where. Well I put the car into park and started my car again when I accelerate the rpm takes a lot longer to catch up to the speed I'm trying to go, so it takes longer to accelerate which is dangerous because cars usually accelerate alot faster than that and I almost got rear ended twice because of it. I parked it for a few days but moved recently so I had to move the car it started and everything but the knocking, or clinking was still there. The following day I went to start my car and know it won't even start and the anti theft light comes...

My back door on the driver side does not open at all from inside or out but the window still works, and the passenger side front door only opens from the inside

The doors will randomly stop working intermittently causing passengers to be stuck in the vehicle and in the event of an emergency making it difficult to safely exit the vehicle. The vehicle while In motion the engine would not function probably and would be flashing different engine light but never a code and the engine would stop

After driving the vehicle at night and turning the engine off certain exterior lighting components would not shut off. Turn signals and reverse lights and brake lamps we stuck in a static on position even when not being activate by turn signal switch or brake pedal being depressed

While at red lights, coasting or waiting in drive-thru the car starts jerking and shaking. Will stall and fail to accelerate, sometimes coming a complete stop. Turning on and off the vehicle only works some of the time. This started in 2020 and went on for months while Hyundai kept "fixing" the car. Coils were replaced in 2020. Now again in 2023, exact same issue. On 9/29/23 car starting jerking while waiting at red light, turning car on and off worked. On 10/1/2023 car starting jerking and shaking while waiting in a drive thru, this time it did not stop no matter how many times I turned my car on and off. They are trying to tell me this is wear and tear on my part. Car is no longer drivable since you never know when this issue will happen.

For more than two years, at irregular intervals, the passenger air bag light on the front panel blinks and the associated chime sounds for about two minutes, then stops. This happens with no passenger in the seat. I have asked the dealer (Fitzgerald Hyundai in Rockville, MD) several times to look into this. My concern is that if the air bag alarm cannot be trusted when there is no passenger, how can it be trusted to work when it needs to? This seems to me to be an unsafe condition. The dealership stated that since the problem occurs intermittently, they cannot determine a cause, and advised me to contact Hyundai Motor America and would likely meet with a representative. I contacted the company in July, and was designated Case No. [XXX]. Over the next two months, in several email communications with "[XXX]," I was informed that I should take the...

The power steering went out as I was driving with my infant in the car. I was making a turn and it completely went out. That is very dangerous.

For the people that have the doors that will not lock or unlock there has been a resolution for that and I am surprised that it isn’t on this site. It’s called “ DOOR LATCH REPLACEMENT(WARRANTY EXTENSION TXXL” number 21-BD-006H you can go to any Hyundai dealership and they will replace it free of charge. I had to do my own research since nobody would help me, including this website to find out the information. This is very disappointing that there was no recall or any information to help anybody regarding this situation. Especially since it’s a huge safety issue. Not to mention when it rains my car leaks which could be the cause. I do not know, but I will never buy another Hyundai ever again. The lack of support from anybody is null and void and you are on your own to find the information. So nobody has...

I was downhill turning right. My vehicle turned off. I started it and it turned off again. Happened again. Turned it back on and was able to continue to drive. Luckily for me there was no other vehicles on the road but could have caused an accident if car was behind me. I am planning on making appointment to take to dealer. No warning signs, engine light flashed on when car turned off but that's it.

When coming to a stop, turn or sometimes when driving throttle goes to zero, oil, engine, and battery light come on and gas peddle no longer works (car no longer accelerates) . Have to turn car all the way off and restart it and it runs fine (all lights turn off and car accelerates) until coming to a stop again (the same exact thing happens). Went to trade it in as soon as person test drove it he almost crashed because the engine stalled again. This has been happening for months but progressively worsened (happens very often now almost causing crashes)

The contact owns a 2017 Hyundai Elantra. The contact stated upon coming to a complete stop, the vehicle accelerated unintendedly over a concrete bar and drove up a hill. The contact depressed the brake pedal but to no avail. The contact steered the vehicle to the right direction to avoid entering a pool. She then crashed into multiple objects including trees, concrete parking bars, and multiple vehicles before coming to a stop. The air bags did not deploy upon impact. The contact was taken to the hospital by ambulance and was treated for injuries to her neck and back. A police report was filed. Due to the failure, the vehicle was towed to an independent tow yard where it was destroyed. Parking barriers and trees were damaged as a result of the failure. The manufacturer was notified of the failure. The failure mileage was approximately 25,000.

Vehicle would do a complete stop without warning while driving. No, engine light isn’t reflected on dashboard of 2017 Hyundai Elantra, went into a complete stop on hwy. Had vehicle checked everything looked good, Hidden problems couldn’t be resolved dealing with matter that could have been deadly if traffic were to occur.

My car was serviced according to the recall sent by Hyundai to install anti-theft security software to my vehicle. My car was locked, broken into, and stolen with the installed security 3 months later. The attached summary outlines the details of the car as it was purchased, recalled, stolen, and recovered, with pictures of the damage included. The Hyundai recall software was not installed correctly or is not effective at preventing vehicle theft for automobiles without immobilizers.

My car is rapidly losing oil at an alarming rate and I believe the 2017 Elantras should be a part of the Oil consumption recall. For at least over the past year at 111,094 miles, my car needs to have the oil refilled at every 3 week period averaging only 1,000 miles. NO CHECK OIL LIGHT ever comes on, and I am only aware of the fact due to diligently checking my car's oil. Countless mechanics have told me of this issue, that it's not normal to consume this much oil. On other forums hundreds of Hyundai users have stepped forward that they are having the same problem. It was cost me countless repairs and when I did go to Hyundai for arguably the same problem (low oil) under warranty, I was never given a new well functioning engine. I also have reason to believe that Hyundai is WELL AWARE...

I can’t pinpoint the issue as it cannot be checked due to check engine light not staying on. I have narrowed it mostly down to being the Ingnition coil packs as I have a cylinder 3 misfire listed. My car started having this issue in 2021. I would eat my lunch in my car and noticed a drop in rpm’s while idle along with vibration of the vehicle. It has progressed to vibrating while driving on the road and not being able to accelerate in a timely manner. I know 2 other people that have the same year of car and they are experiencing these same issues. You can find, on the internet, countless complaints related to the ignition coils failing in these vehicles. A recall needs to be created for the safety of the drivers and passengers in these vehicles. It is irresponsible for a company to use faulty...

I received a mailer and text with my VIN stating I had the 993 recall for my anti-theft software in March. I made an appointment beginning of April for May1st for the recall, after going to the dealership I was informed the recall did not exist and the mailer was wrong. After calling hyundai service I was informed that an appointment could be made to fix it and then after another call to Hyundai I was informed that the recall did not apply to my car, also during this call the lady told me that I can just buy a wheel lock to fix the issue.

Check engine lights keep coming on for ignition coils and engine keeps stalling out. This seems to be a common problem and surprise theres no recall. The engine stalling is very dangerous because of the potential to cause a traffic accident. The problem originally started in August and has continue to happen up to date. I have had close calls for a traffic accidents which is very scary. The mechanic said that the issue was recalled but online says something different. I just want this issue fixed and not just patched.

When driving at night, sometimes the headlights and taillights will shut off leaving the car totally in the dark. This is a SEVERE SAFETY ISSUE as you can no longer see the road and other cars cannot see you. The problem appears to possibly be associated with the light switch, as you can jiggle it and get the lights back on. Also related to this problem of the lights shutting off is the fact that occasionally the lights will come on long after the car has been parked in the garage, which tends to drain the battery. After experiencing this problem, I checked the internet and found numerous other cases of Hyundai Elantra owners reporting the exact same symptoms, so it seems to be a somewhat generic problem. Hyundai’s service department has been unable to isolate the problem on my car. The problem happens randomly and is infrequent but serious...

UNKNOWN. Battery died out on my twice, every two years. Motor needed to be replaced after 5 years.

The contact owned a 2017 Hyundai Elantra. The contact stated while driving approximately 45 MPH, the fuel warning light flickered and the radio activated and deactivated independently. The vehicle was taken to a dealer where it was determined that the vehicle was performing as designed due to a satellite not being connected. On another occasion, the vehicle accelerated on its own and the brake pedal hesitated to respond. The contact depressed the brake pedal to the floorboard in order for the vehicle to come to a stop. The vehicle was taken to another dealer due to the above failures; in addition to shuttering and jerking while depressing on the accelerator, as if it was not receiving fuel. The vehicle was not repaired. The contact did a private diagnosis which indicated electrical system malfunction. The contact was informed to start using a halo battery charger to jump the vehicle. The contact...

Started having intermittent misfires on various cylinders, specifically cylinder 3. (Code P0303) This would mainly cause the engine to stall, or idle. No accidents or injuries to report, but having a car stall out at 80 MPH on the freeway is certainly scary as hell. Just frustration and possible damage to other parts of the engine (spark plugs and some wiring). Took vehicle into local auto shop where they reproduced the problem, but informed me of TSB 20-FL-001H, which can only be fixed by a Hyundai dealership due to the ECM reprogramming and the proprietary nature of the tool to perform that. As such I have taken the vehicle to a Hyundai Dealership where, again, they were able to find and diagnose the problem, as well as determine the spark plugs were likely fouled by the known-faulty ignition coil packs. This is the third time in 75,000 miles I've replaced...

The engine stalled out while driving on the highway. No indicator warning lights came on. The vehicle would not restart. Had to be pushed off the road. Prior to the engine, the tire pressure gauge warning indicator light did not work when tire went flat. I was driving on the interstate 23 back end slid. I pulled off the road and the driver side back tire was completely flat. Put on spare tire.all the lights on dash came on . Went straight to tire garage had 2 tires on back put on. The vehicle is at Tim Short Hyundai dealership in Pikeville Ky. Has been there since 03/11/2022. The engine problem occurred 02/26/22. I had vehicle taken to Carbon Auto Repair shop in Paintsville Ky. The mechanic stated the engine would have to be replaced. I called Hyundai dealership and informed what happened. They scheduled an appointment for inspection. Case...

The car would die while going down the interstate. It would just shut off and you would have to try to safely get off of the road and shut it off and restart it. 60K? miles on the car. We took it to several places to have diagnostic test run and was told it was this sensor then another sensor. Nothing was fixing the problem. Then was told it was the timing. Ended up 2 cam sprockets had to be replaced. Check engine light did come on. This could be a serious hazard if you were not able to get out of the way of other traffic.

Car stalled out. Parked it on should and 15-20 minutes later smoke started coming from the hood. Then fire from behind the engine.

Vehicle loses all acceleration when making turns or coasting slowly. Only way to restore acceleration is to put vehicle in park and turn the key into the off position and then restart the car.

rear door actuators cease to unlatch despite being engaged from the interior and exterior handles to open while unlocked.

My Hyundai Elantra 2017 died while driving on the highway. Started with hesitation when accelerated and died on the highway. The vehicle would not restart
