2017 Hyundai Elantra Electrical Problems

Your 2017 Hyundai Elantra is experiencing unexpected engine stalling and loud mechanical rattling, along with a P0014 diagnostic trouble code. These symptoms may indicate issues with piston rings and engine bearings that are covered under Recall 203 and Service Campaign 966. The engine may need to be inspected and potentially replaced under warranty at no cost to you.

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

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.

I was downhill turning right. My vehicle turned off. I started it and it turned off again.

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).

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.

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.

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

While sitting at a busy red light (02/15/2022), the car just cut off. No warnings, no lights, just cut off. After several attempts, I managed to get car started.

For almost 2 years now I have had issues with my vehicle. In the middle of me driving, all the light would come on and sometimes just the engine light and the car would proceed to stop working. This had happened on the highway while I was pregnant and I almost got into a major accident.

Randomly stall all different times all lights will light up and coast until stopped. Down a hill and to turn it would stall. Go into 8 most serious accidents.

Headlight bulb continues to burn out and bulb wiring melted for some reason.

Doors will not open have to pull the handle 5 or 6 times for the door to finally open the passenger door will not open at all from the outside you have to open it from the inside to let your passenger in the car.

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.

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.

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 engine stalled out while driving on the highway. No indicator warning lights came on. The vehicle would not restart.

Often times the rear video backup camera built into the car blanks out when reversing, randomly. Dealership said it’s possibly bad wiring but would be expensive to investigate, with me on the hook for paying if they can’t locate the issue.

Driving with no signs or dash lights came on to warning me of any issues. Car started acting like it was stalling out one morning parking it at work. Went to leave work had a very slight almost not noticeable knock sound went I started up.

It started with the engine running roughly, so we replaced a coil ourselves. Seemed to fix the issue but a week later there was an intermittent noise from the engine which sounded like a very small exhaust leak (like pffffft). Occasionally, also intermittent, the engine would make a very loud clanky noise.

In january of 2019,my car began shutting off while I was driving. The battery light would appear on the dashboard before the car would completely shut off. I tried to have it fix but nothing worked.

Tl* the contact owns a 2017 hyundai elantra. While driving various speeds, the vehicle lost power and failed to accelerate. All the warning indicators illuminated on the instrument panel.

Coils have been replaced to both number 2 and number 3 cylinders and the car does not have 20k on it yet. The symptoms were poor performance, including a feeling like the vehicle was going to stall and the inability to go much over 45 MPH. Check engine light came on both times that this happened.

1: Driver’s window: don't go up or down, it doesn't respond to control. 2: Headlight warning lights is on all the time because bulbs are burn out so soon after replacement .

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.

Odometer Fraud. The contact owns a 2017 Hyundai Elantra. The contact stated that upon taking the vehicle to an independent mechanic for servicing, the contact was informed that there was a mileage discrepancy.

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.

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

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 .

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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. miles on the car.

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

Car randomly wasn’t a to shut off and check engine light comes on only when gas pedal is pressed. Had taken to dealership to get fixed but it still happens

Hyundai avoids taking care of their cars by sending out general statements for techs to "fix" these issues but they never do they say I didnt hear it when brought in mulitple suspension electrical issues my husbands 2019 hyundai eletrical going out. The engine issue all they did was say didnt do it for me.

Sluggish, shaky and not acceleration engine light comes on intermediately. Code came up p0301. Changed spark plugs, sensor, inclined the catalytic converter two times.

THE PASSENGER SIDE DOOR WILL NOT OPEN FROM THE OUTSIDE IF THE DOOR HAS BEEN LOCKED. IF THE DOOR REMAINS UNLOCKED THE DOOR WILL OPEN FROM THE EXTERIOR FINE, BUT AFTER BEING LOCKED THE DOOR WILL ONLY OPEN FROM THE INSIDE OF THE CAR. OTHERS HAVE POSTED ONLINE REGARDING THE SAME ISSUE.

The doors in the 2017 elantra model stopped working, they do not open from the outside handle and sometimes they do not open from the inside either.

CAR STALLED ON HIGHWAY ON 11-01-2020, PASSED BOTH INSPECTIONS ON 8-29-2020. PURCHASED CAR ON 9-1-2020 THROUGH DRIVETIME. I HAVE INSPECTION PAPER WORK FROM BUYER SHOWING EVERYTHING PASSED. CHANGED OIL ON 10/14/2020 THROUGH JIFFYLUBE WITH ONLY THE AIR FILTER BEING THE ONLY ISSUE FLAGGED.

THE CAR WOULD STALL IN THE MIDDLE OF DRIVING, THE MOST RECENT TIME ON A MAJOR HIGHWAY. THE VEHICLE STALLS WITH NO REASON AT ALL. THIS INCIDENT HAS HAPPENED 5 OR 6 TIMES WITH NO HELP FROM THE DEALER AS THEY HAVE NOT FOUND THE ISSUE. THIS VEHICLE IS UNSAFE TO DRIVE.

TPMS MALFUNCTION INDICATOR LIGHT IS ON. CAR IS SHAKING . ENGINE LIGHT WAS ON

THE DOORS WOULDN'T UNLOCK, THEN DECIDED TO UNLOCK. THE VEHICLE WILL ONLY MAKE THIS LOUD CLICKING NOISE. THE BATTERY TESTS GOOD. THE HEADLIGHTS AND TAILLIGHTS KEEP COMING ON AND OFF EVEN THOUGH THE VEHICLE IS NOT ON AT ALL. ALL SWITCHES ARE TUNED OFF AND IT'S NOT IN ACCC MODE. HAD TO DISCONNECT BATTERY AND WAIT FOR TOW TRUCK.

ONCE AGAIN THE CAR BEGAN TO SHAKE VIOLENTLY AND STARTED LUNGING FORWARD WHILE DRIVING WITHIN CITY LIMITS. CHECK ENGINE WARNING LIGHT CAME ON. I PULLED OVER AND SHUT THE CAR OFF. WHEN I RESTARTED THE CAR, THE CHECK ENGINE LIGHT WAS NO LONGER ILLUMINATED AND THE CAR SEEMED TO DRIVE SOMEWHAT NORMALLY. THIS WAS NOT THE FIRST TIME THIS HAPPENED, AND FROM WHAT I CAN TELL BY READING OTHER SIMILAR COMPLAINTS ON THE NHTSA WEBSITE, SEVERAL PEOPLE ARE HAVING THESE ISSUES AS WELL. IT APPEARS TO BE THE ECM, ENGINE CONTROL MODULE. HYUNDAI NEEDS TO ADDRESS THIS ISSUE ASAP. IT IS VERY DANGEROUS TO DRIVE THIS VEHICLE. DO NOT ALLOW THEM TO SAY YOU NEED NEW SPARK PLUGS OR A SOFTWARE UPDATE. THIS IS A SAFETY ISSUE THAT NEEDS A RECALL IMMEDIATELY.

MY CAR HAD RECENTLY BEGAN TO SHAKE AND BUCK VIOLENTLY WHILE DRIVING WITH NO WARNING LIGHTS OR INDICATORS AT 38,000 MILES. THREE WEEKS AGO BEFORE A REGULAR MAINTENANCE APPOINTMENT AT MY HYUNDAI DEALERSHIP WHERE I BOUGHT THE !CAR, AS I TURNED OVER THE IGNITION AND ACCELERATED THE CAR BEGAN TO BUCK AND SHAKE VIOLENTLY. AS I PRESSED THE GAS, THE CAR WOULD NOT ACCELERATE. I WAS IN THE MIDDLE OF TRAFFIC IN WASHINGTON, D.C. SO ONCE I WAS ABLE TO SAFELY MOVE OVER, I TURNED THE CAR OFF AND BACK OVER. NO SHAKING AND CONTINUED AS NORMAL. ONCE I TOOK THE CAR IN THE FOLLOWING WEEK, I WAS TOLD EVERYTHING WAS FINE AND MADE SURE TO MENTION THE SHAKING AND BUCKING AND WAS TOLD THAT THEY DIDN'T SEE ANYTHING. THE NEXT DAY FOLLOWING SERVICE AND RECEIVING MY CAR BACK, MY CAR BEGAN TO SHAKE VIOLENTLY AGAIN. STILL NO WARNING LIGHT INDICATOR. I RETURNED THE CAR TO THE MECHANIC WHERE MY COIL PACKS WERE UPDATED (I BOUGHT MY CAR MARCH 2017 AND WAS NEVER TOLD ABOUT ANY RECALLS ON COIL PACKS THAT RELEASE LATE 2017 UNTIL THIS MOMENT). ONCE I RECEIVED MY CAR BACK I WAS INFORMED THAT EVERYTHING WAS OKAY. WELL IT WAS NOT. THE NEXT DAY I'M DRIVING MY CAR A SHORT DISTANCE WHEN TWO HARD SHAKES HAPPENED. ONE SOUNDED LIKE TWO METAL PIECES COLLIDING. I PULLED OVER AND TURNED THE CAR OFF AND BACK OVER. THE MALFUNCTION INDICATOR LIGHT IS NOW PERMANENTLY ON. I HAD TO HAVE MY CAR TOWED AND NOW BEING TOLD IT COULD BE THE TRANSMISSION BUT NO UPDATES. SERIOUSLY UNSAFE AND COULD'VE NOW BEEN IN MULTIPLE ACCIDENTS ALTHOUGH I'VE REGULARLY SERVICED AT THE DEALERSHIP I PURCHASED MY CAR.

BOTH BACK DOORS WOULD NOT OPEN. THEY WOULD NOT OPEN FROM THE OUTSIDE OR INSIDE. MAJOR SAFETY ISSUE. I TOOK TO SHOP AND THEY SAID IT WAS ACUTATOR OR SOMETHING LIKE THAT. COST OVER $650 TO FIX. I HAD THE EXTENDED WARRANTY SO I GOT IT FIXED, "FREE". BUT OTHERS MAY NOT BE SO LUCKY. NEVER BEEN IN WRECK, COMPLETELY NOT MY FAULT AT ALL.

OVER THE PAST 2 WEEKS I HAVE A PROBLEM WITH THE HEAD LIGHTS SHUTTING OFF WILE DRIVING ON MAIN HIGHWAYS AT NIGHT. THIS HAS HAPPENED ABOUT 8 OR 9 TIMES. THEY WILL GO OFF WHEN SWITCHING FROM HIGH BEAM TO LOW BEAM. IF I PULL THE LIGHT SWITCH ARM A COUPLE TIMES THEY DO EVENTUALLY COME BACK ON. ALSO TWO TIMES IN THE PAST 2 WEEKS MY PARKING LIGHTS HAVE COME ON WHILE PARKED AND CAR IS SHUT OFF.

10/7/19 - MY CAR BATTERY WAS DEAD AFTER SITTING FOR 8 HOURS PARKED. THERE WAS NO INDICATION THAT IT WAS LOSING POWER AND I HAD BROUGHT MY VEHICLE IN TO BE SERVICED AT A HYUNDAI DEALER A WEEK BEFORE WHERE THEY SAID NO ISSUES WERE SEEN WITH MY BATTERY AT THAT TIME. I GOT A JUMP AND DROVE HOME. THE NEXT MORNING MY CAR WOULD NOT START AGAIN. THE CAR WAS TOWED TO A SHOP BECAUSE IT COULDN'T EVEN BE JUMPED AT THIS POINT. WE WERE TOLD BY THE SAME HYUNDAI DEALER THE BATTERY WAS BEYOND DEAD. AND NEEDED TO BE REPLACED. IT WAS BARELY TWO YEARS OLD AT THIS POINT. BUT WE REPLACED IT. 7/7/20 MY BATTERY IS COMPLETELY DEAD AGAIN. CAR WOULDN'T START AGAIN TODAY WITHOUT WARNING. A REPAIR SHOP TESTED IT AND IT WAS COMPLETELY DRAINED DEAD. THEY SAID IT NEEDS TO BE REPLACED. THIS IS THE SECOND TIME IN LESS THAN ONE YEAR. THIS IS NOT RIGHT.

I experienced the car idling rough while in park and sounding like it wanted to die out. I took to dealer and they replaced an ignition coil.the check engine light came on. Check engine light just came on again yesterday...took it to autozone and they told me it was the ignition coil again.

The door lock actuators on both rear doors have failed preventing the doors from being opened from the inside or the outside because the locks will not disengage. This presents a serious safety issue since any rear passengers are forced to exit the vehicle through the front doors of the vehicle.

While driving down the highway my headlights shut off completely. Leaving us driving in the dark. It has happened multiple times especially when trying to use blinkers or switch high beams on or off.

On aug 26, 2018 the car started missing while driving. Ignition coil was found to be faulty and replaced by the dealer. This was the second incident involving an ignition coil with this vehicle.

Takata recall. I was driving on a highway and tried to speed up, my check engine light came on and the car was not speeding up or slowing down very well. It was slightly shaking.

Engine coils had to be replaced or switched out two times in two weeks. Car stopped in the middle of driving after it was "fixed" the first time. Causing a dangerous situation

Low RPM approx 300, rough idle. A/c usage increses the random intermittent occurrence. 40,000 miles when issue was noticed.

Hi the smart junction box on this vehicle is acting up.

Mechanic has quoted me 2k to fix the issue and replace the Smart junction box .

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.

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.

Two ignition coils have failed. The first was covered under warranty, the second wasn't. We were told the ignition coils are a known issue and we should expect the remaining coils to fail soon.

While driving the passenger seatbelt alarm goes off and nobody is in the seat. This happens randomly for no reason.continues to ding until buckled. Air bag engages.

You can not open the rear doors. By the handles inside or out. Sometime they will open if you wiggle the outside handle alot of time.
