2017 Hyundai Elantra

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.

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.

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.

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.

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.

I BOUGHT MY 2017 ELANTRA SE 2.0 IN APRIL OF 2020 MY CAR KEEPS STALLING WHEN I LET OFF THE GAS AND WHEN I MAKE TURNS LEFT OR RIGHT AT LOW SPEEDS VERY SCARY AND UNSAFE AND ALSO ENGINE NOISES AND SHAKES REAL BAD SOMETIMES AS WELL I STILL OWE 20000 FOR THIS LEMON HYUNDAI SHOULD BE HELD RESPONSIBLE FOR THIS AS ITS BEEN A SERIOUS PROBLEM FOR YEARS FROM WHAT I READ VERY DANGEROUS THIS HAPPENS ON CITY STREETS AND EXPRESSWAY

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.

2017 HYUNDAI ELANTRA CAR STARTED STALLING AT RED LIGHTS AND WHEN STOPPING. ALMOST CRASHED TWICE. IT STARTS BACK UP. IT STARTED 10\12\20. IT HAPPENED A FEW TIMES AND THEN THE CHECK ENGINE LIGHT CAME ON WITH CODE P3006. ABOUT 20 MILES IT WENT OFF. THIS IS VERY DANGEROUS AND NEEDS TO BE FIXED. A LOT OF PEOPLE IS COMPLAINING ABOUT THE SAME ISSUE. IT NEED TO BE RECALLED AND REPAIRED.

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!
