2017 Hyundai Elantra Driver assistance Problems

I own a Hyundai Elantra with approximately 103,000 miles. The vehicle has developed an intermittent issue where the engine will suddenly stall while driving. This most often occurs when I am decelerating and turning, such as when entering or navigating roundabouts. At the time of the stall, multiple warning indicators appear simultaneously, including the check engine light, battery warning light, and a “no key detected” message. There are no prior warning signs before the failure occurs—no unusual noises, no loss of power leading up to the event, and no dashboard warnings in advance. The stall is sudden and unexpected. When the vehicle stalls, I must quickly shift into park and restart the engine. The car restarts immediately without hesitation, and all warning lights disappear. The vehicle then operates normally again until the issue randomly reoccurs. This has happened multiple times. This issue creates a safety risk because the vehicle loses power unexpectedly while in motion, particularly during low-speed turns and in roundabouts, which could increase the risk of a collision due to sudden loss of propulsion and reduced control. The problem has not yet been formally diagnosed by a dealer or independent repair shop, but based on research and similar reported cases, it may be related to an intermittent engine or electrical signal failure. The issue has not yet been inspected by the manufacturer, police, or insurance representatives. UNKNOWN as to the exact failed component, but the failure appears to involve a sudden loss of engine operation without warning, followed by immediate recovery upon restart.

Incident

Apr 22, 2026

The engine of my vehicle malfunctioned. It is available for inspection upon request, it will have to be towed. The problem put myself and others in danger as the car stopped as I was driving in the middle of a 3-lane highway in the far left lane. Others were put in danger as they had to swerve to avoid hitting me. That itself could have caused a chain collision as other vehicles in the middle lane were put in danger. I was also at risk to get rear ended as one might not notice that my speed has stopped increasing. I have already had it towed to a local Hyundai dealership and auto shop; both said it needs a new engine. Towing receipt is shown below. I had no warning lights on my dash prior to the engine failure. A battery light and check engine light appeared after I was able to safely pull to the side of the road and try to start the car again.

Driving at 70mph, another vehicle that is sitting on the grass on the side of the road decides to pulls out in front of me as I'm approaching(no warnings occurred from the collision assist system). I swerved to avoid the other vehicle and then he decides to pull into the lane that I'm trying to get into to avoid him. I break hard but not hard enough to lock the tires up or set off the ABS. Moments after that incident, faults begin to pop up on my instrument cluster, Check Lane Departure Warning System(LDWS), Check Autonomous Emergency Braking System(AEB) and Check Smart High Beam System. I figured that since some of these are safety related that I should report it. My vehicle has approximately 38000 miles.

My vehicle keeps shutting down while I’m driving. It happened 5 times in the past week and twice today. It happens when I’m driving slow to make a turn or after the car has been stopped for a while (i.g. stop light and drive through window). Three out of five times were in areas where I could safely restart my car. The other two were in the middle of a busy expressway while making a turn and passing through a busy intersection. I was almost hit from behind. The car that swerved to avoid hitting me was also nearly hit by a vehicle in the other lane. I’ve done research and several other people had this issue but there’s no recall on my car. I don’t know if it’s a battery issue or electrical wiring, etc., but it is terrifying. Each time it happens my vehicle makes a strange rattling nose and I can’t quite tell where it’s coming from. The car also shakes for a while afterwards.

Car would just stall out while driving! Would have to put car in park and then try to turn back on. Also burning through oil very fast. Had to replace the timing belt just for 20K miles later having the same issue!

Since buying my vehicle new, it has had three ignition coils fail at different times. The car begins to shudder, rough idle, not accelerate and all of a sudden just will not respond to giving it gas. This happens at any speed therefore it is a danger especially entering or exiting highways or switching lanes. It has been unpredictable. The check engine light does come on some of the time as this problem is occurring, not before. The dealer replaced the first two coils (51, 576 miles and 56, 446 miles) under the warranty. The third coil replaced (78, 391 miles), they would not cover under warranty, nor would they replace the 4th coil as a precaution.

Receiving intermittent warnings to check Automatic Emergency Braking System, Lane Departure Warning System, and Automatic High Beam Light System. All three warnings occur together and happen intermittently while driving. Problem may or not begin when first start driving. The problem will also seem to rectify itself after a period of time then begin to cycle again several minutes or hours later. Will occur at any speed or while idling.

Originally I had gottem my oil changed at the Hyundai dealership 2 months before . The car was turning off on me while driving making slow turns or slowing down to 5mph or less. Then my car broke down on me and wouldnt turn on. Mechanic was saying there was no oil in and it created a sludge in the engine basically ruining the car. My check oil light never came on, and the oil was just recently changed so this shouldve been apart of the recall where similar issues happened.

THE ISSUE HAS HAPPENED WHILE MY VEHICLE HAS BEEN STATIONARY AND IN MOTION, ON A CIY STREET, ON A HIGHWAY AND WHILE TURNING. THE CHECK ENGINE LIGHT COMES ON AS THE CAR SHAKES. IF I'M IN MOTION, THE LIGHT WILL STAY ON WHILE MY FOOT IS ON THE ACCELERATOR, TURN OFF WHEN I TAKE IT OFF THE ACCELERATOR AND COME BACK ON WHEN IT REACHES 1RPM'S. IF I'M STOPPED IT WILL JUMP FORWARD WHEN I PRESS THE GAS TO ACCELERATE (THE WHOLE TIME THE CHECK ENGINE LIGHT IS ON). WHILE I'M STATIONARY, IT WILL STAY ON WHILE IT'S AT 1RPM'S OR BELOW. I HAVE GONE TO THE DEALER A COUPLE TIMES ALREADY TO GET TO THE BOTTOM OF IT. THE FIRST TIME THEY TOLD ME IT HAD TO DO WITH MY SPARK PLUGS SO I DID THE SERVICE TO GET THAT TAKEN CARE OF. THE SECOND TIME I WENT THEY TOLD ME THEY COULDN'T FIND ANY CODE TO INDICATE A PROBLEM. HERE WE ARE AGAIN AND I'M HAVING THE SAME ISSUE. THIS IS DANGEROUS AND NEEDS TO BE ADDRESS AS I'VE CURRENTLY READ MANY 2017 HYUNDAI ELANTRA OWNERS ARE HAVING THE SAME ISSUE. I DON'T SEE THE BENEFIT OF BRINGING IT TO THE DEALER AGAIN IF I'M JUST GOING TO PAY FOR A SERVICE THAT ISN'T GOING TO RECTIFY THE PROBLEM AND THEY CONTINUE TO SAY THERE IS NO PROBLEM. I DO HAVE VIDEO TO SHOW THE PROBLEM.

IN FEBRUARY 2020, MY CHECK ENGINE LIGHT CAME ON AFTER MY CAR BEGAN TO SHAKE VIOLENTLY AND LOSE SPEED AS I DROVE ON THE CITY STREETS AND HIGHWAYS.THE SERVICEMAN REPLACED THE COILS IN MY CAR. WITHIN A WEEK, MY CAR STARTED TO SHAKE AND LOSE SPEED AGAIN. I TOOK IT BACK TO THE DEALERSHIP WHERE THEY "FIXED" IT AGAIN TO NO AVAIL. IN EARLY MARCH, MY CAR WAS STILL EXPERIENCING THE SAME PROBLEMS: SHAKING VIOLENTLY AND LOSING SPEED AS I DROVE ON BOTH THE HIGHWAY AND ON CITY STREETS. I CHOSE TO TRY A DIFFERENT SERVICE CENTER. THEY ATTEMPTED TO FIND A PROBLEM WITH MY CAR BY RUNNING THE CODES, BUT HE SAID THAT NOTHING POPPED UP ON THE SCREEN. I TOLD HIM THAT MY CHECK ENGINE LIGHT FLASHES ON AND OFF WHEN I PUT MY FOOT ON AND OFF OF THE ACCELERATOR. HE SENT ME ON MY WAY WITHOUT FIXING MY CAR, BUT HE TOLD ME TO BRING MY CAR BACK INTO THE SERVICE CENTER WITHOUT SHUTTING OFF MY CAR AS SOON AS THE CHECK ENGINE LIGHT COMES ON THE DASHBOARD. HE TOLD ME THAT THIS WAS IMPORTANT, BECAUSE IT WOULD HELP THEM BE ABLE TO DETECT THE ISSUE. WITHIN 15 MINUTES OF PULLING OFF OF THE PARKING LOT, MY CHECK ENGINE LIGHT FLASHED BACK ON AND MY CAR BEGAN TO SHAKE AND LOSE SPEED AGAIN. I TURNED AROUND IMMEDIATELY AND TOOK MY CAR BACK. THEY FLUSHED OUT THE FUEL LINE SYSTEM. WITHIN TWO WEEKS, I BROUGHT MY CAR BACK FOR THE SAME THING, BUT THE SERVICEMAN TOLD ME THAT HE COULD NOT FIND ANY ISSUES SINCE THE COMPUTER SHOWED NO ISSUES. EVERY TIME I TAKE MY CAR INTO A HYUNDAI REPAIR CENTER, THEY TELL ME THAT THEY CANNOT DETECT ANY ISSUES WITH MY CAR, ALTHOUGH I TELL THEM THAT MY CAR BEGINS TO SHAKE AND LOSE SPEED RANDOMLY. IT IS NOW SEPT. 2020, AND I AM STILL HAVING THE SAME ISSUES. I AM SCHEDULED TO TAKE MY CAR INTO A NEW HYUNDAI SERVICE CENTER IN A NEW STATE. THIS IS A DANGEROUS CAR PROBLEM THAT THREATENS THE SAFETY OF ME AND OTHER DRIVERS ON THE ROAD. HYUNDAI NEEDS TO TAKE ACTION NOW!

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.
