2015 HYUNDAI SONATA Engine Problems

HIGH SPEED ENGINE STALL: WHILE DRIVING AT HIGHWAY SPEEDS ON AUGUST 5, 2016, MY VEHICLE SUDDENLY LOST POWER WHILE DRIVING ON THE HIGHWAY, WHICH RESULTED IN VEHICLE COMING TO A STOP. ON ATTEMPTING TO RESTART THE ENGINE, THE ENGINE HAD SEIZED AND WOULD NOT RESTART AND THE RESTART ATTEMPT WAS ACCOMPANIED BY NOISE FROM THE ENGINE AND VIBRATIONS CAUSING THE ENTIRE VEHICLE TO SHAKE. VEHICLE HAD TO BE TOWED TO THE DEALER FOR REPAIRS.

WE HAD A LIFE-THREATENING INCIDENT WHEN THE ENGINE REMAINED RUNNING IN OUR ATTACHED GARAGE WHEN THE DRIVER FORGOT TO TURN OFF THE ENGINE AND WENT IN THE HOUSE WITH THE KEY FOB IN HIS POCKET. EVENTUALLY WE SMELLED FUMES AND RESOLVED THE PROBLEM.

FAULTY ENGINE CONTROL MODULE - WHILE DRIVING HOME FROM VACATION, AFTER APPROXIMATELY 9 HOURS ON THE HIGHWAY, OUR CHECK ENGINE LIGHT CAME ON IN OUR 2015 SONATA. WE WERE ONLY TWO HOURS AWAY FROM HOME AND THE LIGHT WASN'T FLASHING, SO WE CONTINUED DRIVING. WHILE ON AN ACCELERATION RAMP CHANGING HIGHWAYS, THE CAR SPUTTERED AND SEEMED TO BE LOSING POWER, EVEN WITH THE GAS PEDAL COMPLETELY FLOORED. THANKFULLY, THE ENGINE DIDN'T SHUT OFF AND WE WERE ABLE TO CONTINUE DRIVING, HOWEVER, THE ENGINE SEEMED TO "MIS-FIRE" AND THE CAR WAS HESITATING AND RIDING ROUGH. THE NEXT DAY, THE CHECK ENGINE LIGHT WENT OFF. A FEW DAYS LATER, IT CAME BACK ON, AND WHILE TRYING TO GAIN ENOUGH SPEED TO GET ON THE HIGHWAY, THE ENGINE FELT LIKE IT WAS CUTTING OUT AND BEGAN TO RIDE ROUGH AGAIN. I IMMEDIATELY CALLED HYUNDAI TO MAKE AN APPOINTMENT TO HAVE THE CAR LOOKED...

1ST EVENT JUNE 10 2016 - CAR STOPPED ON THE FWY AT SPEED OVER 65 MPH. STEPPED ON THE GAS PEDAL AND WAS NO POWER. ATTEMPT TO RESTART AND CAR RUN ROUGH. CAR TOWED TO DEALER (TUTTLE CLICK-HYUNDAI -IRVINE,CA.) 2ND EVENT JULY 18 2016 - DRIVING ON FWY AT SPEEDS OVER 65 MPH, GAS PEDAL STARTS VIBRATING, DRIVING BECOME ROUGH, CLICKING NOISE FROM ENGINE WHEN IDLING. FILE COMPLAIN WITH DEALER, DEALER SAY IT DID NOT FIND ANYTHING, BLAME THE SITUATION TO COSTCO GAS, AND IT SAYS THAT THE CAR REQUIRES TO USE DIFFERENT TYPE OF GAS (SUCH: CHEVRON, SHELL).

ON THREE DIFFERENT OCCASIONS THE DASH FLASHED "CHECK TPMS" MEANING CHECK AIR IN THE TIRES. ON ALL 3 OCCASIONS THE CAR WOULD NOT GO INTO GEAR.THE NEXT OCCASION THE CHECK TPMS CAME ON SO I PUT AIR IN THE TIRES AND DROVE AROUND THE CORNER TO RESET THE TIRE PRESSURE MONITOR (COMPUTER). UPON COMING AROUND THE CORNER TO PARK THE CAR THE CHECK TPMS WARNING CAME ON AGAIN THE CAR POWERED DOWN AND I COASTED TO PARK. THE NEXT MORNING I CALLED THE DEALERSHIP TO HAVE THE CAR CHECKED I WAS TOLD FROM JARED THAT THE TECHNICIAN DID A SOFTWARE UPDATE AND THAT " HE THINKS, MAYBE, MIGHT HAVE FIXED THE PROBLEM. AT THIS POINT I DID NOT PICK UP THE CAR BECAUSE THEY COULD NOT GUARANTEE THE CAR HAD BEEN FIXED AND THAT IT WILL NOT DIE WHILE DRIVING AROUND HYUNDAI SERVICE DEPARTMENT SAID THEY WERE NOT SURE BECAUSE...

ENGINE OIL CONSUMPTION: 1 QUARTER EVERY 1,000 MILES AND INCREASING.

ON MAY 30, 2016 AT AROUND 9 PM I STOPPED MY 2015 HYUNDAI SONATA AT A TRAFFIC LIGHT AND WITHOUT WARNING THE ENGINE DIED. I WAS ALMOST REAR ENDED WHEN THE LIGHT CHANGED TO GREEN. NO WARNING LIGHTS CAME ON UNTIL THE ENGINE DIED. AFTER ABOUT TWO MINUTES I WAS ABLE TO RESTART THE CAR. I TURNED LEFT AT THE INTERSECTION WHERE MY CAR HAD STALLED AND IN THE MIDDLE OF THE INTERSECTION THE ENGINE DIED AGAIN. I THOUGHT I WAS GOING TO DIE. EXITED THE CAR AND WAVED TRAFFIC BY. TWO MORE MINUTES AND THE ENGINE STARTED AGAIN AND I WAS ABLE TO DRIVE THE THREE REMAINING BLOCKS TO MY HOME. I HAD THE CAR TOWED TO OURISMAN HYUNDAI WHERE I BOUGHT IT. THEY HAVE HAD IT EVER SINCE. TODAY, JUNE 6, OURISMAN CALLED AND SAID THEY COULD NOT DUPLICATE THE PROBLEM AND I SHOULD RETURN THE LOANER CAR...

MY 2015 HYUNDAI SONATA HAS BEEN BACK AND FORTH TO THE DEALER. EVERY TIME I TURN AROUND THE THIS CAR HAS A RECALL. I DON'T EVEN KNOW ABOUT THE RECALL UNTIL A LIGHT POPS UP OR I HAVE A WEIRD NOISE WHILE DRIVING. ONE TIME THE CAR JUST FELT WEIRD WHILE DRIVING AND I WENT TO GET IT CHECKED OUT AND FOUND OUT ABOUT THE RECALLS. FIRST SEATBELT, THEN ENGINE LINE NEEDED REPLACING, THEN ANOTHER PART NEEDED REPLACING, THEN ANOTHER. AFTER GOING THERE MONDAY FOR FOR THE ENGINE IMMOBILIZER, THE BRAKE HOLD LIGHT BEING I WAS TOLD SOMETHING WAS REPLACED, AND OH A RECALL WAS HANDLED. THEN TO COME BACK FRIDAY AND AFTER 4-5 HOURS BE TOLD THE ABS HAS TO BE REPLACED, MEANING I HAVE TO COME BACK BECAUSE IT HAS TO BE ORDERED.

TL* THE CONTACT OWNS A 2015 HYUNDAI SONATA. WHILE DRIVING APPROXIMATELY 60 MPH, THE OIL AND CHECK ENGINE LIGHTS SUDDENLY ILLUMINATED BEFORE THE ENGINE BEGAN TO SPUTTER AND STALL. THE VEHICLE WAS TOWED TO THE DEALER WHO DID NOT YET DETERMINE THE CAUSE OF THE FAILURE. NO ADDITIONAL INFORMATION WAS AVAILABLE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 56,000.

I PURCHASED A USED 2015 HYUNDAI SONATA WITH 43K MILES. I HAVE HAD IT FOR THREE MONTHS WITH MINOR PROBLEMS SUCH AS SLUGGISH ACCELERATION, HARD DECELERATION WHEN REMOVING FOOT FROM GAS PEDAL, AND A NOISY ENGINE. HOWEVER, ON 4-8-2016 AT ABOUT 7:30 AM, I WAS ATTEMPTING A LEFT TURN ON A BUSY METROPOLITAN STREET WHEN THE 2015 HYUNDAI SONATA SHUT DOWN SUDDENLY, COMPLETELY TURNED OFF! ALL THE WARNING LIGHTS ON THE DASH LIT UP LIKE A CHRISTMAS TREE AND THEN WENT DEAD. THE 2015 SONATA CAME TO A STOP, AND THERE WAS A TRUCK APPROACHING AT A HIGH SPEED RATE THAT HAD TO SWERVE AROUND ME TO PREVENT A COLLISION WITH ME. I WAS LUCKY THE DRIVER WAS PAYING ATTENTION. THIS PROBLEM IS VERY DANGEROUS AND IT IS JUST A MATTER OF TIME BEFORE SOMEONE IS KILLED DUE TO THIS PROBLEM, WHICH SEEMS TO BE OCCURRING IN MANY 2015 HYUNDAI...

TL* THE CONTACT OWNS A 2015 HYUNDAI SONATA. WHILE EXITING THE VEHICLE AT 40 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE WAS ABLE TO BE PULLED OVER TO THE SIDE OF THE ROAD, BUT COULD NOT BE RESTARTED. THE VEHICLE WAS TOWED TO A DEALER WHERE IT WAS DIAGNOSED THAT THE ENGINE SEIZED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 4,000.

ENGINE CEASES AND ALL THE LIGHTS ON THE DASH BOARD FLASH AND STAY ON AND THE CAR STALLS. THIS HAPPENED FOR THE 5TH TIME YESTERDAY ON RT 78. I ALMOST COURSED A COLLUSION BECAUSE MY CAR LOST POWER AND STALLED ON THE HIGHWAY. I MANAGED TO MOVE OVER TO THE SHOULDER AS QUICK I COULD. AFTER A FEW MINUTES LATER THE ENGINE STARTED. THIS HAPPENS BOTH WHEN THE CAR IS PARKED AND IN MOTION. THIS IS VERY DANGEROUS. HAVE TAKEN THE CAR BACK TO THE DEALERSHIP AND THEY SAY THEY FIXED THE PROBLEM BUT IT KEEPS HAPPENING . I HAVE GOOGLE THIS PROBLEM AND FOUND OTHER OWNERS EXPERIENCING THE SAME PROBLEM. I THINK THE SHOULD HAVE A RECALL FOR THIS ENGINE TO GET IT FIXED.

I PURCHASED A NEW 2015 HYUNDAI SONATA 8 MOS AGO AND TWO DAYS AGO WHILE DRIVING ON A LOCAL HIGHWAY I HEARD A LOUD KNOCKING SOUND WHILE ACCELERATING. YESTERDAY I TOOK IT TO THE HYUNDAI DEALER SERVICE CTR WHERE I PURCHASED THE VEHICLE AND I WAS TOLD THAT I NEED A NEW ENGINE DUE TO THERE BEING METAL SHAVINGS IN THE MOTOR.

WHILE DRIVING AND TURNING ONTO AN INTERSECTION THE CAR'S ENGINE QUIETLY TURNED OFF LEAVING ME IN THE MIDDLE OF ONCOMING TRAFFIC. I PRESSED THE GAS PEDAL BUT NO REACTION. I HAD TO PUT THE CAR ON PARK AND TURN THE KEY OFF AND ATTEMPT TO RESTART THE CAR. THIS WORKED FOR NOW. THE CAR HAS ONLY 6664 MILES ON IT. I HAVE HAD THE CAR FOR ONLY 6 MONTHS. NO PENDING MAINTENANCE IS DUE FOR THIS TO HAVE HAPPENED. THERE ARE ALSO NO PENDING RECALLS DUE. SO THIS IS OBVIOUSLY A VERY DANGEROUS SITUATION AND COMMON AMONG OTHERS ON THE COMPLAINT BOARD.

WHILE DRIVING ON A HIGHWAY, THE CAR UNEXPECTEDLY LOST ENGINE POWER; THE CAR ENGINE DID NOT RESPOND WHENEVER I QUICKLY STEPPED ON THE GAS PEDAL; THEREBY MAKING ANY QUICK DEFENSIVE MANEUVER IMPOSSIBLE. IT'S AS IF THE CAR ENGINE WAS STARVED FOR AIR AND BECAME UNRESPONSIVE FOR QUICK ACCELERATION. DEALERSHIP DETERMINED ERROR CODE P2600, INTAKE RUNNER CONTROL PROBLEM. DUE TO THIS PROBLEM OF IMPAIRED ACCELERATION GETTING, ON AND OFF MAJOR HIGHWAYS WAS PARTICULARLY DANGEROUS SINCE QUICK POWER WAS NON-EXISTENT AND AVOIDING OTHER CARS QUICKLY WAS NOT POSSIBLE. TRULY A SAFETY ISSUE!

TL* THE CONTACT OWNS A 2015 HYUNDAI SONATA. WHILE DRIVING 65 MPH, THE VEHICLE BEGAN TO DECELERATE AS IF THE BRAKES WERE BEING APPLIED.

THE FAILURE OCCURRED PREVIOUSLY. THE VEHICLE WAS BEING REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 11,000.

I BOUGHT A 2015 HYUNDAI SONATA ECO ON AUG 30, 2015 AND SHORTLY AFTER PURCHASE LOW TIRE PRESSURE LIGHT AND DISPLAY CAME ON WHILE DRIVING 65 MPH INDICATING THAT THE REAR DRIVE WHEEL WAS AT 9PSI. I PULLED OVER ON THE SIDE OF THE ROAD AND INSPECTED TIRE AND THE TIRE HAD A NORMAL FEEL. DROVE FOR 10 MINS AND TIRE PRESSURE WENT BACK UP TO 35 PSI. ON 11/15 THE BATTERY AND OIL LIGHT CAME ON WHILE THE VEHICLE WAS IN DRIVE AND IMMEDIATELY FOLLOWING THE LIGHTS THE ENGINE SHUT OFF. I SAT IN THE MIDDLE OF THE ROAD AND HAD TO RESTART MY VEHICLE AND THEN DROVE IT TO THE DEALERSHIP. THE DEALERSHIP SAYS, "2691 PERFORMED ALL SYSTEM FAULT CODE SEARCH AND TSB SEARCH. NO FAULT CODES STORED AT THIS TIME AND NO RELATED TSBS FOR CUSTOMER CONCERN AS DESCRIBED." THE DEALERSHIP LATER FOUND A WARNING SAYING TO...

I BOUGHT THIS NEW CAR A FEW MONTHS AGO. AT 1089 MILES ENGINE OVERHEATED WHILE IN TRAFFIC. I MANAGE TO STOP SAFELY AND I CALLED ROADSIDE TO TOW THE CAR TO SERVICE. SECOND DAY THEY TOLD ME THAT THEY NEED TO REPLACE THE ENGINE ACCORDING TO HYUNDAI TECH LINE. THIS FOR ME WAS A RED FLAG THAT SOMETHING IS REALLY WRONG WITH THAT CAR. THEY FOUND COOLANT INSIDE THE ENGINE AND THIS WAS THEIR DIAGNOSIS, JSUT LIKE THIS. THE REPLACED THE ENGINE WITH A REMANUFACTURED ONE AND FEW WEEKS LATER I ENDED UP IN SERVICE AGAIN FOR COOLANT LEAKS. THEY REPLACED 2 BIG HOUSES. NOT LONG AFTER THIS I ENDED UP AGAIN IN SERVICE CAUSE COOLANT LEVEL IS LOW ON THE OVERFILL COMPARTMENT. THEY SAID IS NOTHING WRONG AND ALL THE TESTS ARE GOOD.

THIS HYUNDAI SONOTA HAS A PUSH BUTTON IGNITION. ONCE THE ENGINE IS STARTED, A PERSON CAN LEAVE THE VEHICLE WITH THE KEY FOB IN THEIR POCKET AND THE ENGINE STAYS RUNNING AND WILL NOT SHUT OFF. THIS IS IN VIOLATION OF FEDERAL MOTOR VEHICLE SAFETY STANDARD 114. ONCE THE KEY IS REMOVED FROM THE VEHICLE THE ENGINE SHOULD SHUT OFF. THIS ENGINE IS SO QUIET YOU CANNOT EVEN HEAR IT RUNNING WHILE IN THE VEHICLE AND IF SOMEONE IS PARTIALLY COLOR BLIND YOU CAN BARELY SEE THE RED AND GREEN INDICATOR. THIS ENGINE WILL RUN IN AN IDLE STATE NO MATTER WHERE THE KEY CAUSING RISK OF FIRE, CARBON MONOXIDE POISINING AND DEATH AND INJURY TO ANYONE NEAR THIS VEHICLE IF LEFT RUNNING AND SINCE THE CAR STAYS RUNNING ONCE IT IS STARTED ANYONE CAN WALK AWAY WITH THE KEY FOB IN THEIR POCKET AND THE CAR STAYS RUNNING NO...

2015 HYUNDAI SONATA 2T - SLOW ACCELERATION; CAR WILL CONTINUE TO MOVE WHEN FOOT ON BREAK; LOUD ENGINE NOISE; ENGINE LIGHT ALWAYS ON. TOOK CAR TO DEALER THEY SAID IT WAS A RECALL ISSUE THAT THEY REPAIRED. DROVE CAR TWO DAYS ENGINE LIGHT CAME BACK ON. NOW DEALER STATES THEY ARE WAITING FOR PARTS TO COME IN TO FIX.

I HAVE THE LIMITED EDITION, 2.0L TURBOCHARGED. WHEN THE ENGINE IS COLD, AND IF YOU TIP-IN AGGRESSIVELY, YOU CAN HEAR SOME SCREECHING SOUND ABOVE 5000 RPM OF THE ENGINE, EASILY ACHIEVED IN SECOND OR THIRD GEAR. THE TURBO IS DESIGNED BY MITSUBISHI AND I KNEW SOMEONE WHO WORKS THERE. AFTER LISTENING THE SOUND, HE INDICATED IT IS A CASE OF TURBOCHARGER IMBALANCE. I AM NOT SURE IF IT A DESIGN ISSUE OR MINE IS JUST A ONE OFF CASE. I HAVE CONTACTED HYUNDAI LAST WEEK, HAVEN'T GOTTEN ANY RESPONSE YET. I BELIEVE THE TURBO HAS TO BE REPLACED. IF IT NOT RESOLVED, OVER A PERIOD OF TIME DUE TO EXCESSIVE VIBRATION, THE JOURNAL BEARING MAY FAIL AND THE TURBO COULD BLAST. IF ANYONE HAS THE SAME ISSUE, PLEASE TAKE IT SERIOUSLY.

THIS IS THE SECOND 2015 HYUNDAI SONATA WHICH HAD COMPUTER PROBLEMS. THE FIRST ONE PURCHASED IN JULY 2014, HYUNDAI TOOK IT BACK IN DEC 2014 BECAUSE OF THE COMPUTER PROBLEMS. THE SECOND PICKED UP IN DEC 2014 CURRENTLY HAS APPROXIMATELY 2900MILES WITH THE SAME BASIC COMPUTER ISSUES. BOTH VEHICLES WHEN TRAVELING FROM ABOUT 40 TO 65MPH THE ENGINE'S COMPUTER SYSTEM WOULD CUT THE SPEED DOWN AND LOSE COMPRESSION TO APPROXIMATELY 20MPH TO PROTECT THE VEHICLE FROM SOME KIND OF ENGINE DAMAGE. YOU WOULD BE FORCED TO GET OFF THE ROAD AND SHUT THE VEHICLE OFF. ONCE THE ENGINE WAS OFF 5 MINUTES THE ENGINE WOULD START UP, THE CHECK ENGINE/ANTI SKID LIGHTS WOULD STAY ON SO THAT THE DEALERSHIP COULD SEE WHAT CODES WERE CAUSING THE PROBLEM. THE FIRST VEHICLE WAS ASSIGNED A CASE# BY HYUNDAI -CASE# 6788232 AND WAS FINALLY TAKEN BACK BY HYUNDAI IN DEC 2014 AFTER BEING...

ON 04/06/2016, THE VEHICLE'S ENGINE BEGAN TO RUN ROUGH AND HESITATED. LACK OF ACCELERATION, EVEN AT 4000 RPMS (TOP SPEED 20 MPH AT 4000 RPMS). THE VEHICLE BEGAN TO STALL AND REQUIRED THE GAS PEDAL TO BE PRESSED DUE TO LOW RPMS AT IDLE. THE PROBLEM IS INTERMITTENT, WITH NO WARNING TO THE OPERATOR, AND POSES A SIGNIFICANT SAFETY RISK ON ROADWAYS WITH SPEED LIMITS ABOVE 40 MPH. NO ENGINE WARNING LIGHT CAME ON TO WARN THE OPERATOR. AFTER THREE OCCURRENCES OF THIS PROBLEM, IN LESS THAN 24 HOURS, THE VEHICLE, WITH ONLY 1,351 MILES ON THE ODOMETER, WAS TAKEN TO DEALERSHIP FOR SERVICE ON 4/7/2015. AFTER REPLACING, THE FUEL PUMP, THE VEHICLE WAS RETURNED TO THE OWNER ON 04/10/2015. LESS THAN 2 MILES AFTER PICKING THE VEHICLE UP FROM SERVICE, THE PROBLEM OCCURRED AGAIN, ON A 50 MPH ROADWAY. THE OPERATOR WAS VERY CONCERNED FOR HER SAFETY AS OTHER...

THIS IS A NEW HYUNDAI SONATA 2015. THE ENGINE CHECK LIGHT CAME ON AND THE ENGINE STARTED RUNNING ERRATICALLY. THE FOLLOWING SYMPTOMS CAN BE A SAFETY CONCERNS: 1. SOMETIMES WHEN IDLING AT INTERSECTION THE ENGINE RPM GOES UP ALL OF A SUDDEN AND THE CAR STARTS MOVING FORWARD AND ONLY A STRONGER PUSH ON THE BRAKES STOPS THE CAR FROM CRASHING INTO THE VEHICLE AHEAD OR RUNNING A RED LIGHT. 2. WHEN DRIVING ON HIGHWAY THE CAR LACKS POWER EVEN IF THE GAS PEDAL IS DEPRESSED ALL THE WAY INTO THE FLOOR. THIS PREVENTS THE CAR FROM PROPERLY ACCELERATING WHEN MERGING INTO INCOMING TRAFFIC. I TOOK THE CAR TO THE DEALERSHIP AND THEY IDENTIFIED THE ISSUE IS "CAM COVER LEAKING" AND "OIL COMING THROUGH THE OIL SEAL MAKING THE MOTOR DO WEIRD THINGS". THESE ARE THE QUOTES FROM THE PAPER I GOT FROM THE DEALER. THE CAR SPENT 2 WEEKS...
