TL* THE CONTACT OWNS A 2007 HYUNDAI SONATA. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, SHE HEARD RATTLING AND TAPPING SOUNDS. THE VEHICLE LOSS MOTIVE POWER WHILE ACCELERATING. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC AND INFORMED THAT THERE WAS A ROD KNOCK AND VALVE TAP PRESENT AND THAT THE ENGINE NEEDED TO BE REPLACED. KEARNY MESA HYUNDAI (4797 CONVOY ST, SAN DIEGO, CA 92111) WAS CONTACTED AND INFORMED THAT THE VEHICLE HAD TO BE REPAIRED OUT OF POCKET. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 99,800.

MY TRANSMISSION WENT

I HAD BEEN DRIVING ON THE TURNPIKE FOR ALMOST AN HOUR WHEN I STARTED TO HEAR A CLICKING NOISE. I WAS DRIVING ABOUT 70 MPH AND PRESSED DOWN ON THE ACCELERATOR. WHEN I DID SO, THERE WAS A LOUD BANG AND SUDDENLY, SMOKE FILLED UNDER THE HOOD AND ALSO CAME OUT THE EXHAUST PIPE. I ALSO SAW DEBRIS FLEW OUT FROM UNDER THE CAR, LOOKING LIKE IT WAS COMING FROM THE TAIL PIPE. I PULLED OVER AND OPENED THE HOOD TO FIND OIL EVERYWHERE, MORE SMOKE FLOODING OUT OF THE HOOD AND BITS OF METAL DEBRIS ALL OVER. OIL WAS LEAKING ALL OVER THE SIDE OF THE ROAD. THE MECHANIC HAS JUDGED THAT THE ENGINE BURST WHILE I WAS DRIVING IT.

OIL LEAK FROM VALVE COVER GASKET DROPPED ON ALTERNATOR. DAMAGE TO ALTERNATOR CAUSED VEHICLE TO SHUT OFF WHILE GOING 60MPH ON AN INTERSTATE. MULTIPLE LIGHTS ON THE DASH ILLUMINATED (INCLUDING THE ENGINE AND BATTERY LIGHTS, THE SEAT BELT LIGHT STARTED FLASHING), I LOST POWER TO THE RADIO AND THE LIGHTS INSIDE THE CAR STOPPED WORKING, QUICKLY AFTER THESE TWO ISSUES STARTED I LOST THE ABILITY TO ACCELERATE (AGAIN, WHILE GOING 60MPH ON AN INTERSTATE). VERBATIM TEXT FROM COMPLAINT 14V415000 FOR THE HYUNDAI VERACRUZ (INCLUDING THE MODEL YEAR 2007)- "AN UNEXPECTED FAILURE OF MOTIVE POWER WHILE DRIVING INCREASES THE RISK OF A CRASH." I BELIEVE THAT THIS RECALL SHOULD BE EXPANDED TO OTHER HYUNDAI VEHICLES AS THERE ARE A NUMBER OF OTHER COMPLAINTS ONLINE FOR SONATAS FOR MULTIPLE YEARS, INCLUDING 2007. MY LOCAL DEALERSHIP QUOTED ME $1372.43 TO REPLACE THE ALTERNATOR, VALVE COVER GASKET, AND BATTERY (ATTACHED).

TIMING CHAIN TENSIONER WANT IT REPLACED

VEHICLE IN MOTION ON FREEWAY IN RUSH HOUR TRAFFIC, SPEED VARYING FROM 0-30 MPH. ENGINE SPONTANEOUSLY BEGAN MAKING LOUD METALLIC KNOCKING NOISE WHEN ACCELERATOR WAS PRESSED. NO ENGINE WARNING LIGHT ACTIVATED. MECHANIC FOUND NO LOSS OF OIL PRESSURE. FRONT END DISASSEMBLY SHOWED METAL BITS IN THE OIL PAN. ENGINE CONSIDERED TO BE UNSAFE TO DRIVE DUE TO THREAT OF FIRE. CAUSE BELIEVED TO BE CRANKSHAFT BEARINGS.

TL* THE CONTACT OWNS A 2007 HYUNDAI SONATA. WHILE STATIONARY, THE VEHICLE CAUGHT FIRE AND THE CONTACT NOTICED SMOKE UNDERNEATH THE DASHBOARD. AFTER EXITING THE VEHICLE, THE CONTACT NOTICED FLAMES UNDER THE HOOD OF THE VEHICLE. A POLICE REPORT WAS FILED. THE CONTACT CALLED THE FIRE DEPARTMENT, BUT THE FIRE EXTINGUISHED ON ITS OWN. THERE WERE NO INJURIES. WHITE WATER MOTORS IN WEST HARRISON, INDIANA WAS MADE AWARE OF THE FIRE AND STATED THAT THERE WAS NO RECALL ON THE VEHICLE. THE MANUFACTURER WAS MADE AWARE OF THE FIRE. THE FAILURE MILEAGE WAS APPROXIMATELY 207,000.

VEHICLE WAS IN MOTION AND ENGINE BEGAN KNOCKING. STOPPED DRIVING IT. REMOVAL OF ENGINE HAS SHOWN THAT IT HAS THROWN A ROD AND SPUN THE INSERT OUT OF IT. THIS HAS HAPPENED ON OTHER HYUNDAI VEHICLES BUT THE RECALL ISN'T GOING BACK FAR ENOUGH.

TL* THE CONTACT OWNS A 2007 HYUNDAI SONATA. WHILE DRIVING 40 MPH, THE ENGINE SEIZED AND THE CHECK ENGINE AND OIL WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE ENGINE NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE AND VIN WERE UNKNOWN.

2007 HYUNDAI SONATA. CONSUMER WRITES IN REGARDS TO ENGINE FAILURE. *LD *JS

THE ISSUE IS THE TENSIONER FOR THE TIMING CHAIN. THE TENSIONER FAILED, CAUSING A VERY EXPENSIVE ENGINE REPAIR. THERE IS A RECALL ON THE 6 CYL TENSIONER, BUT NOT THE 4 CYL WHICH I HAVE. MY RESEARCH SAYS THE SAME TENSIONERS WERE USED FOR BOTH ENGINES. IT FAILED AT 169,000. IT WAS STATIONARY IN A PARKING LOT WHEN IT FAILED TO START. IT WOULD TURNOVER BUT WOULD NOT CATCH. I HAVE ALL THE DAMAGED PARTS SAVED BY THE MECHANIC. IF I WAS DRIVING WHEN IT FAILED, IT WOULD HAVE NOT ONLY BLOWN THE ENGINE BUT MOST LIKELY WOULD HAVE STOPPED MY CAR ON WHATEVER ROAD I WAS DRIVING ON, INCLUDING AN EXPRESSWAY.

2007 HYUNDAI SONATA. CONSUMER WRITES IN REGARDS TO ENGINE FAILURE. *LD THE CONSUMER STATED THAT THE ENGINE BLOCK HAD A CRACK IN IT. THE CONSUMER BELIEVED THAT THE FAILURE WAS PREMATURE. THE ENGINE WAS REPAIRED AND THE CONSUMER REQUESTED TO BE REIMBURSED. THE ENGINE WAS OUT OF WARRANTY *JS

ENGINE MAKES A VERY LOUD NOISE AND CANNOT BE USED. THIS CAR WAS VERY WELL MAINTAINED AND JUST OUT OF WARRANTY. LOUD NOISE IN CYLINDER AND CRANK SHAFT. HYUNDAI SAYS ENGINE NEEDS TO BE REPLACED. THIS CAN HAPPEN TO ANYONE WHO WOULD BE LEFT STRANDED OR IN A BAD SITUATION. HYUNDAI DOES ACKNOWLEDGE A PROBLEM, BUT SO FAR NO RECALL.

THE ENGINE STARTED MAKING METALLIC CLICKING AND KNOCKING NOISES ABOUT A WEEK AGO. I TOOK IT TO MY MECHANIC AND BY THEN IT STARTED SQUEAKING AND SQUEALING. HE SAID IT WAS CATASTROPHIC ENGINE FAILURE AND ASKED IF I HAD EVER LET IT RUN OUT OF OIL, WHICH I NEVER DID. WHEN DRIVING TO MY MECHANIC, LOST A LOT OF POWER ON AN ENTRANCE RAMP TO HIGHWAY AND ALMOST GOT IN AN ACCIDENT. MY MECHANIC NEVER SEEN IN AN ENGINE WITH < 200,000 MILES UNLESS AN OIL EVENT, SO HE BELIEVES THIS WAS DUE TO A MANUFACTURING DEFECT. IT IS INTERESTING THAT THE 2011 AND 2012 SONATA WAS RECALLED FOR EXACTLY THIS TYPE OF ISSUE AS WELL. I WONDER IF THE PROBLEMS WERE ALSO EXISTING ON PREVIOUS YEAR MODELS, SUCH AS THE 2007 MODEL.

TRAVELING AT 50 MPH HIGHWAY OFF RAMP. A RATTLING IN THE ENGINE - BROKEN ROD - LOSS OF POWER AND NO ACCELERATION.

AT 107,000 MILES THE ENGINE STARTED TICKING. I DROVE TO THE DEALER AND THE FIRST MECHANIC WHO LISTENED - DIDN'T EVEN OPEN THE HOOD, JUST LISTENED SAID "YOU NEED A NEW ENGINE". COST OF ENGINE REPLACEMENT WITH LABOR WAS ESTIMATED $4000-$5000 WHICH WAS MORE THAN THE CAR WAS WORTH, SO I DROVE IT ANOTHER 20,000+ MILES WITH THE TICKING GETTING LOUDER UNTIL ONE MORNING IT BLEW A HOLE IN THE BLOCK ON THE FREEWAY. I'VE HEARD OF THIS WITH OTHER PEOPLE AND THERE LOW MILEAGE SONATAS. SEEMS TO ME HYUNDAI IS REFUSING TO ADDRESS THE ISSUE OF A BAD ENGINE - THIS WAS A SINGLE OWNER 7 YEAR OLD CAR WITH THE ORIGINAL BATTERY. YEP, THE BATTERY LASTED LONGER THAN THE ENGINE! *TR

THE ENGINE FAILED WITH A BENT ROD IN THE ENGINE. ENGINE NEEDS TO BE REPLACED. *JS
