2015 Hyundai Sonata Engine

THE HOSE LEADING TO THE TURBO HAS MELTED OFF. THE CLAMP WITH HOSE RUBBER REMAIN FIRMLY ATTACHED TO THE TURBO WITH THE REMAINDER OF THE HOSE HAS FALLEN BELOW THE TURBO AIR INLET. THE ISSUE OCCURRED SUDDENLY FROM ONE NIGHT TO THE NEXT MORNING. UNDER LOAD, THE TURBO OPERATIONAL NOISE WAS EXTREMELY LOUD COMPARED TO USUAL.

WHITE DRIVING EITHER IN MOTION OR STOPPED BEHIND A LIGHT, ENGINE STARTS TO SHAKE AND STALL. THIS MAKE THE CAR SHARE HEAVILY AND NUDGE FORWARDS AND BACKWARDS UNTIL THE CALL STALLS OUT. THEN THE DASH GETS LIT UP WITH ALL THE CHECK ENGINE LIGHTS. THEN, PRESSING THE START BUTTON MULTIPLE TIMES UNTIL THE VEHICLES STARTS. THE CAR DOES THIS EVERY SO OFTEN. YOU DRIVE OFF, IT SHAKES AND STALLS, IT HAS A HARD TIME STARTING. THEN IT STARTS AND EVERYTHING SEEMS NORMAL. THIS HAPPENS AT LEAST 1 OR 2 TIMES A MONTH. CURRENTLY VEHICLE AT DEAL SERVICE TO SEE WHAT IS GOING ON. GOOGLE SEARCH RESULTED IN OTHER WITH SIMILAR ISSUES. SEE LINK BELOW IF NECESSARY.

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 AT. WHEN I MADE THE APPOINTMENT, THE SCHEDULER INDICATED THERE WAS A RECALL ON MY CAR. I ASKED IF IT HAD ANYTHING TO DO WITH THE CHECK ENGINE LIGHT BEING ON, AND I WAS TOLD IT DIDN'T. I TOOK THE CAR IN, AND AFTER 2 OR 3 HOURS THEY CALLED AND SAID MY CAR WAS READY AND THEY HAD REPLACED A FAULTY ECM (ENGINE CONTROL MODULE), WHICH HAD CAUSED THE CHECK ENGINE LIGHT TO COME ON. NO MENTION WAS MADE OF THE RECALL. AFTER READING ALL THE POSTS ON THIS SITE, I AM CONVINCED THE PROBLEMS PEOPLE ARE HAVING WITH THEIR ENGINES DYING IS THE RESULT OF A FAULTY ECM. I HAVE SEARCHED EVERYWHERE ON THE INTERNET ABOUT HYUNDAI RECALLING VEHICLES THAT COULD BE AFFECTED, AND I COULD FIND ABSOLUTELY NOTHING. WE NEVER RECEIVED A RECALL NOTICE BY MAIL OR EMAIL EITHER. SYMPTOMS OF A BAD OR FAILING ECM INCLUDE THE CHECK ENGINE LIGHT COMING ON, ENGINE STALLING, MISFIRE OR PERFORMANCE ISSUES. SHAME ON HYUNDAI FOR NOT PROTECTING THEIR CUSTOMERS AGAINST A POTENTIALLY LIFE-THREATENING HAZARD AS THIS.

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.

THE CAR AT ABOUT 7K MILES STARTED USING OIL A QT, EVERY 2500 MI. THEY ARE TELLING ME IT IS NORMAL . IT IS POLLUTING MORE THAN THAN NORMAL PLUS FOULING THE PLUGS OVER TIME

AT ABOUT 7000 MI. THE ENGINE BEGAN BURNING OIL AT 13 K MI.IT HAS BEEN TO THE DEALER TWICE THEY SAY IT IS NORMAL BURNING 3/4 QT IN LESS THAN 3K MILES IS MORE POLLUTION THAN NORMAL I WOULD THINK

LEASED 2015 HYUNDAI SONATA SE TRIM IN 05/2015. 1) IN 02/16 --> SLUGGISH ACCELERATION REPORTED TO DEALER AND HE APPLIED SOFTWARE UPDATE TO ECM. 2) 10/05/2016 ---> WHILE DRIVING CAR STARTED TO SPUTTER , SHUDDER AND HEAVY SMOKE (MOSTLY WHITE) COMING FROM TAIL PIPE. CAR WAS NOT ACCELERATING AT ALL. IT WAS VERY DANGEROUS SITUATION AND FELT THAT CAR WAS NOT UNDER CONTROL. FINALLY IT CAME TO STOP. AFTER FEW MINUTES, TRIED TO START AND SUCCEEDED IN 3RD/4TH ATTEMPT. TOOK IT TO NEARBY HYUNDAI DEALER, AND AS PER THEM, THEY UPDATED ECM (ENGINE CONTROL MODULE) SOFTWARE. 3) 10/20/2016 --> ISSUE APPEARED AGAIN WITH SAME SYMPTOMS.CAR IS WITH DEALER AND HE IS LOOKING INTO IT. I AM VERY CONCERNED ABOUT SAFETY. *TR

VEHICLE HAS JUST OVER 12000 MILES. ON 10/16/2016 VEHICLE JUST STALLED WHILE DRIVING IT. I HAD BACKED OUT OF A PARKING SPOT, PUT IN DRIVE, CAR MOVED FORWARD ABOUT 15 FEET AND THEN IT SHOOK AND MADE HORRIBLE NOISES AND STALLED. TOOK 3 ATTEMPTS TO RESTART. BROUGHT TO DEALER, DIAGNOSTICS REVEALED NOTHING AND CAR WAS RELEASED. ON 10/19/2016 CAR STALLED AGAIN WHILE DRIVING. I WAS DRIVING THROUGH APARTMENT PARKING LOT AND IT JUST STALLED. OIL AND BATTERY LIGHTS CAME ON. THIS TIME HAD IT TOWED TO DEALER (TOO SCARED TO DRIVE IT IN RUSH HOUR TRAFFIC). DEALER RAN DIAGNOSTICS WITH NO RESULTS. THEY ARE TRYING TO DUPLICATE EPISODES. HOW LONG DOES THIS MEAN THEY NEED TO KEEP THE VEHICLE? GAVE ME FREE RENTAL DAY 1, BUT AFTER THAT? THIS IS A SERIOUS SAFETY ISSUE. AND FROM WHAT I CAN SEE VISITING WEBSITES, ALSO A COMMONLY OCCURRING PROBLEM. CAN THE NTSB HELP BEFORE MANY PEOPLE ARE KILLED? I DON'T WANT TO DRIVE MY CAR ANYMORE. I TRADED IN AN 8 YEAR OLD CAR BECAUSE I WANTED SOMETHING NEW AND RELIABLE. NOT SURE THIS WAS SUCH A GOOD IDEA. DEALER HAS BEEN WORKING DILIGENTLY TO IDENTIFY THE PROBLEM SO THEY CAN REMEDY IT, BUT WITHOUT ANY DIAGNOSTIC ERRORS, THEY ARE FORCED TO RETURN THE CAR TO ME. I REALLY DON'T WANT TO DRIVE IT UNTIL I KNOW THE PROBLEM HAS BEEN IDENTIFIED AND CORRECTED. WHAT IF I WERE IN THE MIDDLE OF NOWHERE AND THIS HAPPENED, BY MYSELF, AND AFTER HOURS? THIS IS WHAT OCCURRED 10/16/16 AND I WAS LUCKY I GOT IT RESTARTED. *TR

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.

TL* THE CONTACT OWNED A 2015 HYUNDAI SONATA. THE CONTACT STATED THAT WHILE DRIVING AT 35 MPH, THE VEHICLE STALLED AND SMOKE STARTED TO EMIT FROM UNDERNEATH THE HOOD AND THE AIR CONDITIONING VENTS. THE VEHICLE WAS PULLED TO THE SIDE AND THE CONTACT QUICKLY JUMPED OUT OF THE VEHICLE JUST BEFORE THE ENGINE COMPARTMENT EXPLODED AND THE HOOD FLEW OPEN. THE CONTACT STATED THAT THE FIRE DEPARTMENT CAME TO THE SCENE AND EXTINGUISHED THE FIRE. A POLICE REPORT WAS FILED BUT THERE WAS NO FIRE REPORT. THE CONTACT STATED THAT THERE WERE NO INJURIES. THE REMAINS OF THE VEHICLE WAS TOWED TO A JUNK YARD. THE FAILURE MILEAGE WAS 27,000.

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.

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

TL* THE CONTACT OWNS A 2015 HYUNDAI SONATA. WHILE DRIVING 65 MPH, THE VEHICLE BEGAN TO LOSE POWER AND THE CHECK ENGINE LIGHT ILLUMINATED. THE VEHICLE BEGAN TO DECREASE IN SPEED WHEN THE ACCELERATOR PEDAL WAS DEPRESSED. THE VEHICLE WAS TOWED TO A DEALER WHERE IT WAS DIAGNOSED THAT THE TURBO FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 30,000. THE VIN WAS NOT AVAILABLE.

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.

ON AUGUST 18, 2015 I WAS SITING AT A STOP LIGHT AND MY CAR JUST SHUT OFF, I WAITED A FEW SECONDS AND IT STARTED BACK UP AGAIN, I TOOK IT TO COCOA HYUNDAI THEY RAN EVERY TEST CALLED ME AND TOLD ME THAT THEY COULD NOT FIND NOTHING WRONG WITH MY VEHICLE. ON SEPTEMBER 21 I WAS DRIVING HOME FROM WORK MY CAR JUST DIED IT STARTED JERKING AND THE ENGINE LIGHT AND SKID LIGHT CAME ON I WAITED AND IT RESTARTED IT MOVED MAYBE ABOUT AN INCH OR SO AND SHUT DOWN AGAIN, I PULLED TO THE SIDE OF THE ROAD AND LET IT SIT AND IT RESTARTED I PROCEED TO TAKE IT TO COCOA HYUNDAI AND TOLD THEM THAT THIS IS THE (2) SECOND TIME I HAVE HAD THIS PROBLEM THEY KEPT THE CAR RAN EVERY TEST CALLED THE HYUNDAI TECH AND THEY PROCEEDED TO INFORM ME THAT THEY COULD NOT FIND ANYTHING WRONG WITH THIS CAR. SO I SAID OF I GUESS THIS IS NORMAL FOR A 2015 TO DO THIS, I AM IN FEAR OF DRIVING THIS VEHICLE BECAUSE I'M NOT SURE WHEN OR WHERE IT WILL SHUT DOWN. SOMETHING IS SERIOUSLY WRONG WITH THIS VEHICLE AND IT IS PUTTING MY LIFE IN DANGER...

AT 11:38 AM, CAR SUDDENLY LOST POWER WHILE IN MIDDLE OF INTERSECTION, ALL THE SYMBOLS ON THE DASHBOARD LIT UP, PUSHING ON THROTTLE HAD ABSOLUTELY NO EFFECT ON CARS MOVEMENT. CAR WOULD GO FORWARD AT IDLE SPEED ONLY. RECEIVED A MESSAGE ON NAVIGATION SCREEN AND AN EMAIL SAYING ?A POSSIBLE CONDITION WITH YOUR ENGINE CONTROL SYSTEM HAS BEEN DETECTED. HYUNDAI RECOMMENDS A FULL SYSTEM CHECK SOON. TO SCHEDULE AN APPOINTMENT WITH A HYUNDAI DEALER, SAY SERVICE LINK WHEN ASKED TO SAY THE NAME OF A SERVICE. PULLED TO SIDE OF ROAD, TURNED OFF ENGINE. RESTARTED ENGINE, ONLY CHECK ENGINE LIGHT WAS ON, BUT ACCELERATION STILL ROUGH.

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 OUT OF SERVICE FOR WELL OVER 35 DAYS DUE TO THE CONTINUED COMPUTER PROBLEMS. THE REPLACEMENT VEHICLE RECENTLY HAD 3 INCIDENTS WHILE TRAVELING AT APPROX. 65MPH THE ENGINE WOULD GO TO 20MPH WITHOUT WARNING. THE ONLY EXCEPTION WAS THAT WHEN I RESTARTED THE VEHICLE THE CHECK ENGINE LIGHT WOULD REMAIN ON UNTIL I TURNED OFF THE VEHICLE. WHEN I RESTARTED THE VEHICLE THE CHECK ENGINE LIGHT WENT OFF LEAVING ME IN A DIFFICULT POSITION WHEN BRINGING THE VEHICLE IN FOR SERVICE, THE COMPUTER DIDN'T STORE THE EVENT TO VERIFY THE PROBLEM. THE DEALER SAID IF IT OCCURS AGAIN TO LET THEM KNOW AND THEY WOULD CONTACT THEIR TECHNICAL HOTLINE. THE SERVICE DEPT KNOWS THERE IS A PROBLEM SINCE THEY WENT THROUGH THIS WITH ME ON THE FIRST VEHICLE, THAT'S WHY THEY TOOK THE VEHICLE BACK. I ESTABLISHED A NEW CASE FILE [XXX] ON 4/16/2015 WITH HYUNDAI CONSUMER AFFAIRS. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

TL* THE CONTACT OWNS A 2015 HYUNDAI SONATA. WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE SUDDENLY SHUT OFF. THE VEHICLE WAS TOWED TO THE DEALER WHO WAS UNABLE TO DUPLICATE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 3,000.

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 WITH THE DEALER. THEY REPLACED THE CAM COVER. BUT 2 DAYS LATER THE PROBLEM APPEARED AGAIN. I'M AFRAID OF DRIVING THIS CAR NOW, BECAUSE ENGINE BEHAVES ERRATICALLY. AND THIS CAR ONLY HAS 3500 MILES ON IT. *TR
