2014 Hyundai Elantra Driver assistance Problems

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.

This has occurred three separate times, but this report explains what happened during the most recent occurrence. I was driving at 40 mph. The car in front of me hit their brakes, so I lightly tapped my brakes to slow down. When I tapped the gas pedal, the car would not increase speed. The check engine light, oil light, and battery light each turned on simultaneously. The car then stalled completely, but the lights remained on and the car didn’t lose power. I hit the brakes (which were now hard to push down), hit my emergency flashes so that the car behind me would pass me, pulled over to the side of the road, and then I turned off the car. When I turned the car back on, 30 seconds later, all of the lights were off and the car started with no issue.

The piston rings do not seal leading to increased oil consumption and very low oil. My safety was put at risk because when I pulled out into traffic that was going at a high speed I could not accelerate. There was no warning or indication that this was going on prior to this incident. Yes this has been confirmed by a Hyundai dealership and the component was inspected. There was no warning sign before this incident.

While driving over the last month, the car shuts off with no warning. There are no check engine or other lights that come on once it shuts down. There does not appear to be any consistency in the occurences, sometimes while idling, sometimes while driving 40 mph. Up until recently, the car would restart once I put it in neutral, but it now does not restart right away.

I was driving the vehicle normally down the highway. When I exited the highway, I came to a stop light and made a complete stop at which point the engine stalled. I restarted the vehicle, the check engine light appeared, but I couldn’t get it to register any RPMs and I was left stranded in a busy intersection until help arrived.

my car will stall randomly at stop signs and red lights with absolutely no warning. it’s super dangerous and has almost caused a wreck. i have taken it to mechanic and no codes are being thrown and it’s showing nothing is wrong. it’s a matter of time a accident happens and someone gets hurt. I would definitely like to figure this out!

2014 ELANTRA DRIVING THE CAR IN TOWN AT SLOW SPEEDS, USUALLY AROUND 15-25 MILES AN HOUR, WITH RPMS AT ABOUT 1250. FIRST NOTICED AN ISSUE WITH EXTREMELY JERKY DRIVING, BUT ADDED GAS AND THE PROBLEM WENT AWAY, AND I THOUGHT IT WAS A ONE-TIME THING. ABOUT A WEEK LATER, IT HAPPENED AGAIN. I SET AN APPOINTMENT TO THE MURDOCK HYUNDAI OF MURRAY UTAH TO SOLVE THIS ISSUE THAT WAS PUTTING MY FAMILY AND MY SECURITY IN RISK. ON JUNE 18TH AROUND 6 PM, THE DID A DIAGNOSTIC CHECK IN THE DEALERSHIP AND THEN, THEY RECOMMENDED ME TO CLEAN MY GAS INJECTORS, TO DO A TUNE-UP, TO DO AN ALIGNMENT AND TO ADD NEW FOUR TIRES CHANGE SINCE THEY WERE TOTALLY DAMAGED., SOME KIND OF HYUNDAI SOLVENT CLEANERS FOR THE GAS ENGINE. ALL OF THE SERVICES HAD A TOTAL OF $1043 DOLLARS. I THOUGHT IT WAS ALL IT NEEDED BUT NOT IT WAS NOT. A FEW DAYS LATER, THE CAR STARTED TO HAVE THE SAME SYMPTOMS AS BEFORE, LOSING POWER AGAIN, ENGINE SLOWING DOWN AND BAD GAS MILEAGE... I SET UP ANOTHER APPOINTMENT WITH THE DEALERSHIP.

TAKATA RECALL ON 9/23/2018, ABOUT AN HOUR AFTER A RAINSTORM (CAR WAS GARAGED DURING STORM) MY CAR WAS IN MOTION AT 40 MPH IN THE LEFT LANE ON A CURVE OF A SOUTHBOUND INTERSTATE EXIT I275. THE CAR SUDDENLY WENT SIDEWAYS, AND BEGAN FISHTAILING. I TRIED TO PUMP THE BREAKS BUT THEY WERE NOT WORKING. THE VEHICLE THEN SMASHED THE FRONT SIDE OF BUMPER INTO THE GUARD RAIL, AND PUSHED ME ACROSS TWO TRAFFIC LANES. THE VEHICLE STOPPED IN THE RIGHT LANE, FACING NORTH IN A SOUTHBOUND EXIT. I TRIED TO PUT IT IN REVERSE TO GET INTO THE SHOULDER, AND THERE WAS NO ACCELERATION. THE ENGINE HAD SHUT OFF ON ME WHILE DRIVING ON THE INTERSTATE. I DO NOT KNOW WHAT FAILED THE ENGINE, OR WHY IT SHUT OFF. HYUNDAI CORPORATE WAS CONTACTED AND THEY OPENED A CASE, AND PERFORMED A FULL INSPECTION. ON 11/12/18 HYUNDAI CLAIMED "WE CANNOT AGREE THAT THE ACCIDENT INVOLVED A PRODUCT DEFECT AND ARE DECLINING ANY FINANCIAL ASSISTANCE." A THIRD PARTY MECHANIC WAS THEN CONTACTED, AND FOUND CODE C1555 AND A FAILING VVTI CYLINOID. THERE IS NO RECALL. THERE IS NO WAY TO PROVE THIS CAR IS UNSAFE WITH THE ROUTES I HAVE TAKEN SO FAR. I WILL NOT ACCEPT THIS ANSWER. THE ENGINE OF THIS CAR SHUT OFF AND COULD HAVE BEEN FATAL. IT IS ALSO TERRIFYING TO THINK ABOUT WHO WOULD TO BE BLAMED FOR SUCH A FATAL OR DANGEROUS ACCIDENT SINCE HYUNDAI "COULDN'T FIND ANY DEFECT." I ASKED FOR RESULTS OF THE SCAN AND THE CASE MANAGER, CHRISTINA REPLIED THAT I AM NOT AUTHORIZED TO SEE THEM, FOR "RESULTS ARE FOR PROPRIETARY USE ONLY." THIS COMPANY NEEDS TO OWN UP TO THEIR RISKY PRODUCT!

THE ESC (TRACTION CONTROL) RANDOMLY COMES ON WHILE CRUISING AT HIGHWAY SPEEDS ON STRAIGHT, LEVEL, DRY ROADS (OFTEN ON INTERSTATES). SOMETIMES THE ABS LIGHTS ALSO LIGHT UP. BRAKES ARE APPLIED AND POWER TO THE ENGINE IS SUSPENDED MAKING THE CAN NEARLY IMPOSSIBLE TO CONTROL PROPERLY. MY CAR HAS BEEN IN THE SHOP NOW UNDER WARRANTY FOR OVER 60 CONSECUTIVE DAYS AND THE DEALERSHIP AND HYUNDAI CANNOT DETERMINE THE REASON FOR THIS MALFUNCTION. AFTER REPEATED REQUESTS TO HAVE THE CAR REPAIRED UNDER WARRANTY, THIS CAR HAS BEEN IN AN ACCIDENT AND I HAVE ASKED HYUNDAI TO DETERMINE THE RELEVANCE OF THIS REPEATED MALFUNCTION IN THE ACCIDENT WHERE THE CAR WOULD NOT STOP QUICKLY ENOUGH TO AVOID ANOTHER MOTORIST. THIS CAR WAS PURCHASED USED WITH 20,185 MILES ON IT AND CURRENTLY HAS AROUND 22K MILES AND IS UNDER A BUMPER TO BUMPER WARRANTY.

08-26-16 WHILE PULLING INTO A PARKING SPACE AT A PUBLIC PARK WHILE DOING LESS THAN 5 MILES PER HOUR, I EXPERIENCED RAPID UNINTENDED ACCELERATION, PLOWED THROUGH A FENCE, SIDESWIPED A TREE, WENT OFF A GRASSY MEDIAN BACK UP ONTO A GRASSY MEDIAN AND THEN BOUNCED OFF OF THAT BEFORE THE CAR FINALLY CAME TO REST. MY BRAKES DID NOT WORK AND I HAD NO CONTROL OVER THE VEHICLE. IT IS A MIRACLE THAT I AM NOT DEAD AS THE PARK IS ON A VERY BUSY 4 LANE ROAD AND IS USUALLY FULL OF CHILDREN.
