NHTSA Complaint #11169886 — 2012 HYUNDAI SONATA HYBRID

WHILE DRIVING THE CAR WILL RANDOMLY REV VERY HIGH IT STARTED ABOUT 3 WEEKA AGO WHILE DRIVING AT AROUND AN AVERAGE OF 45MPH IN CITY. IT WAS INITIALLY JUST REVVING 3-4 TIMES UNTIL I HIT THE BREAK AND IT WAS ISOLATED TO ONE INCIDENT PER DRIVE. BUT LAST NIGHT AFTER DRIVING ON I-25 AT HIGHWAY SPEED I TURNED TO A SLOWER BUSY STREET MORE STOP AND GO TRAFFIC AND THE CAR STARTED REVVING AGAIN ONLY THIS TIME IT DID NOT STOP AFTER ONE INCIDENT. AS SOON AS I HIT THE ACCELERATOR IT WENT INTO A REVVING FIT. AND DIDNT STOP I COULDN'T EVEN DRIVE IT BECAUSE I COULD NOT GET IT TO ACCELERATE. I TRIED TURNING OFF BLUE DRIVE AND TRIED SHIFTING DOWN TO 1ST GEAR SO I COULD AT LEAST MAKE IT AT 10-15MPH BUT IT REVVED UP EVEN IN MANUAL GEAR. I HAD TO PARK IT FOR THE NIGHT IN A PRETTY SKETCHY NEIGHBORHOOD AND CALL AN UBER. THE SYSTEM DIDN'T POPULATE ANY CODES AND NO SERVICE LIGHTS CAME ON. THEN, THIS MORNING WHEN I WENT BACK TO GET THE CAR TO A MECHANIC AND IT WAS ACCELERATING FINE THOUGH IT WAS SLUGGISH. I MANAGED TO MAKE IT 2.5 MILES TO A MECHANIC WITHOUT INCIDENT BUT STILL NO SERVICE ENGINE LIGHT.
