2010 Hyundai Santa Fe Speed Control & Cruise Problems

Driving approximately 70-75mph on highway with cruise control set. Car starts to make rattling sound & engine warning light goes on, car struggles to accelerate and hovers around 60mph. Upon inspection of engine oil in car, fresh oil has been burned up quickly! Added 1 quart. Drove 45mins at 70-75mph. Notice Engine light on again. Check engine oil. Had quickly burned through 1qt! Add new quart of oil. Let car rest overnight. Driving 70mph without use of cruise control. Then use cruise control. After a bit car engine sounds of rattling & struggling to accelerate. RPM gauge seen going up & down. Through rear view mirror I see lots of bluish smoke. Pull over to let engine rest. Check oil = still 3/4. Use engine dectection device. Indicates that cylinders 3 &4 misfiring. Reset car warning indicator with my detection device. Finish drive going 60mph to arrive at destination without car engine warning going back on.

ON 6/17/2018 @ APPROXIMATELY 5:00PM WHILE DRIVING MY SANTA FE, I BEGAN TO HAVE SURGING POWER. I ATTEMPTED TO DISENGAGE THE CRUISE CONTROL BUT COULD NOT. I WOULD SLOW DOWN ONLY TO SPEED RIGHT BACK UP AS IF I HAD PUSHED THE RESUME BUTTON, I HAD NOT. I ATTEMPTED TO SHIFT INTO NEUTRAL HOWEVER MY GEER SHIFTER WAS LOCKED INTO DRIVE & I COULDN'T GET THE SHIFTER OUT OF DRIVE. AT TIMES THE CAR WOULD START TO SLOW DOWN AFTER PU MPING THE BREAKS ONLY TO HAVE A SURGE OF POWER AGAIN. AS I WAS DRIVING, I CAME UP TO A SHARP CURVE & WASN'T ABLE TO SLOW DOWN THEREFORE I ENDED UP ROLLING THE SUV & FURTHER SLAMMING TO A LARGE HILL. I WAS INJURED IN THIS ACCIDENT DUE TO ROLLING MY CAR! THIS HAPPENED BC I BELIEVE THE CRUISE CONTROL GOT STUCK & LOCKED UP MY TRANSMISSION!!! I ALSO COULDN'T TURN THE KEY OFF SINCE THE CAR WAS IN DRIVE.

ON MONDAY, JULY 14, 2014, MY WIFE RODE HER SANTA FE ON A STRAIGHT ROAD ACCELERATING SLIGHTLY UPHILL WHEN THE ENGINE STALLED. ON THURS. DEC. 5, 2013, I HAD A SIMILAR EXPERIENCE, WHICH I REPORTED TO YOU AT THE TIME. THIS IS THE SECOND TIME THIS HAS HAPPENED WITH THIS CAR. AGAIN NOBODY TOUCHED THE IGNITION KEY WHICH HAS NOTHING HANGING ON IT EXCEPT THE ALARM AND DOOR LOCK DONGLE. MY WIFE ALSO SUDDENLY LOST POWER STEERING AND POWER BRAKES, AND LUCKILY THERE WAS NO OTHER TRAFFIC, WHICH COULD HAVE CAUSED AN ACCIDENT. SHE WAS ABLE TO BRING THE CAR TO A SAFE STOP AND THEN WAS ABLE TO RESTART THE ENGINE AND CONTINUE HER TRIP. THE 2010 CAR HAD A FULL TANK OF GAS AND HAS ABOUT 50000 MILES ON THE ODOMETER. IT'S AWD AND HAS A 6 CYL. ENGINE. COULD THIS BE RELATED TO THE IGNITION SWITCH PROBLEM THAT HAS PLAGUED SO MANY GM CARS? NEEDLESS TO SAY WE ARE WORRIED DRIVING THE CAR BECAUSE IF THIS INCIDENT OCCURS AT HIGH SPEED, A SERIOUS ACCIDENT COULD BE THE RESULT. DO YOU KNOW OF ANY SIMILAR EXPERIENCE? WHAT DO YOU ADVISE?

I HAD JUST PULLED INTO THE DRIVEWAY OF A HOUSE I OWN THAT I RENT; I WAS THERE TO MEET MY TENANTS TO DISCUSS A COUPLE OF REPAIRS THAT NEEDED TO BE DONE IN THE HOUSE. I WAS SLOWING THE CAR WITH MY FOOT ON THE BRAKE AS I APPROACHED THE END OF THE DRIVEWAY BY THE SIDE DOOR OF THE HOUSE. THEN I HEARD A SUDDEN, EXTREMELY LOUD ENGINE NOISE THAT SOUNDED LIKE THE ENGINE REVVING VERY FAST AND THE CAR SUDDENLY ACCELERATED. I WAS PROPELLED FORWARD ABOUT 50 FEET INTO THE BACK YARD AND CRASHED INTO SOME LILAC BUSHES DIRECTLY AHEAD OF ME AND INTO THE STEEP DIRT BANK BEHIND THE BUSHES, WHICH STOPPED THE CAR. THERE IS NO GARAGE AND THE DRIVEWAY ENDS WHERE THE LAWN BEGINS. THE FRONT END OF THE CAR IS QUITE DAMAGED AND THE VEHICLE IS PRESENTLY IN THE DEALER'S REPAIR GARAGE. ON THE INTERNET, MY SON FOUND MANY REPORTS OF INCIDENTS OF SUDDEN ACCELERATION FOR THE HYUNDAI SANTA FE FOR MY MODEL YEAR AND FOR OTHER RECENT YEARS AND HE SUGGESTED I FILE THIS REPORT WITH THE NHTSA. *TR

DEC 16, 2011 AROUND 9:45AM MY HUSBAND AND I HAD JUST PICKED MY SISTER AND BROTHER IN LAW UP FROM THE AIRPORT AND HAD DECIDED ON GRABBING SOME BREAKFAST FROM WAFFLE HOUSE. I HAD COME TO A COMPLETE STOP TO TURN RIGHT INTO THE RESTAURANT PARKING LOT; I THEN DROVE ABOUT 15 FEET GOING MAYBE 5 MPH TO COME TO A COMPLETE STOP TO THEN TURN RIGHT TO GET READY TO ENTER INTO THE PARKING SPOT. ONCE I RELEASED MY FOOT FROM THE BREAK (NOT NEEDING TO APPLY THE GAS AS MY PARKING WAS MAYBE 20 FEET TO MY RIGHT AND THE CAR SHOULD ACCELERATE AT A LOW SPEED ON ITS OWN) THE 2010 SANTA FE TOOK OFF AT AN ALARMING SPEED I PRESSED MY FOOT ALL WAY BACK DOWN ON THE BRAKE BUT THE CAR DID NOT STOP. I THEN LOOKED DOWN TO SEE IF MY FOOT WAS ON THE BRAKE IT WAS DOWN TO THE FLOOR BOARD. THE SANTA FE WENT OVER THE PARKING SPOT AND INTO THE BUSHES THEN STOPPED ITSELF. THANK GOD BECAUSE THE ROAD WAS ON THE OTHER SIDE OF THE BUSHES. I HAVE NEVER EXPERIENCED A VEHICLE DOING THIS? I THEN CONTACTED THE SERVICE DEPARTMENT AT HYUNDAI WHERE I PURCHASED MY CAR AND WAS TOLD THAT ONLY HAPPENS TO TOYOTA THAT THEY HAVE NEVER HEARD OF IT HAPPENING TO THEIR VEHICLES. MY HUSBAND AND I TOOK THE CAR BACK TO THE DEALERSHIP WHERE WE E-MAILED AND REVIEWED OF THE PHOTOS WITH MARK ODAT AND 2 OTHER MANAGERS SHOWING THE DAMAGE THAT ACCRUED WHILE GOING OVER THE CEMENT CURB. I DON'T KNOW IF THERE WERE ANY DAMAGES UNDER MY CAR, I NOTICED SCRATCHES TO THE PAINT AND A BENT LICENSE PLATE (WHICH I BENT BACK INTO PLACE). I HAD BROUGHT MY SANTA FE UP TO THE DEALERSHIP BACK IN LATE AUGUST OR EARLY SEPTEMBER 2011 WITH A COMPLAINT AND SPOKE DIRECTLY TO THE SERVICE MANAGER JR THAT TWICE WHEN I WAS ON MY TRIP FROM HOUSTON, TX TO ATLANTA, GA WHEN USING THE CRUISE CONTROL ONCE I TOUCHED THE BRAKE TO TURN THE CRUISE CONTROL OFF THE SANTA FE WOULD ACCELERATE INSTEAD OF DECELERATE AND THAT IT HAD A HARD TIME GOING UP HILLS. *TR
