2009 Hyundai Elantra Speed Control & Cruise Problems

Drove about 1 hour using cruise control part of the time. Don't usually use it, but used it 2 months ago with no problem. After 1.5 hour visit, drove home. Did not use cruise control, but at last 10 minutes acceleration issue started where car would "rev" even though I was not accelerating. Able to manage it with brake and normal driving. Tried to reset cruise (turn on/off), but car still had episodes of "revving". Did not accelerate to dangerous level and controllable. After car sat in garage for 2 hours, I drove out of neighborhood to empty stretch of road and accelerated to 50 with no problems and no revving of engine. Service check scheduled.

I WAS DRIVING ON THE HIGHWAY WITH CRUISE CONTROL ON. WHEN I TURNED THE CRUISE CONTROL OFF, THE CAR WOULD NOT SLOW DOWN. IN FACT, THE CAR INCREASED IN SPEED EVEN WITH THE CRUISE CONTROL COMPLETELY OFF. I STEPPED ON THE BREAKS AND IT SLOWED DOWN A BIT, BUT AS SOON AS I STEPPED OFF THE BREAK THE CAR WOULD START TO ACCELERATE. I MADE MY WAY OFF THE EXIT AND PRESSED THE BREAK HARD AND WITH THE HELP WITH EMERGENCY BREAK, I WAS ABLE TO STOP AT THE SIDE OF THE EXIT AND WAS ABLE TO TURN OFF THE CAR. AS SOON AS I STARTED UP THE CAR AGAIN, THE ENGINE REVVED REAL HIGH. I OPENED THE HOOD OF THE CAR AND SAW THAT PLASTIC ENGINE COVER HAD SPLIT AND THE BROKEN PIECE WAS JAMMING THE THROTTLE CABLE. I BELIEVE THIS IS A HIGHLY DANGEROUS ISSUE. I'VE INCLUDED PICTURES OF THE BROKEN PART AND WHERE THE BROKEN PART WAS TOUCHING THE THROTTLE.

ACCELERATION FAULTY CRUSE CONTROL

I WAS PULLING OUT OF A PARKING LOT TODAY GOING ABOUT 20MPH WHEN MY CAR STARTED SPEEDING UP. I STARTED BRAKING, BUT THE ENGINE SEEMED TO JUST WANT TO GO. I WAS COMING TO A STOP SIGN AND CARS WERE COMING SO I JUST TURNED OFF THE SWITCH AND IT STOPPED. WHEN I RESTARTED IT, IT SEEMED NORMAL AND I DROVE VERY CAREFULLY HOME. I AM GOING TO TRY TO RENT A CAR TILL THIS GETS CHECKED. IT SCARED ME TO DEATH AND HAS NEVER HAPPENED BEFORE.

CAR ACCILERATER GETS STUCK AND WILL ACCELERATE WHEN CAR IS FIRST STARTED, WHETHER STATIONARY OR IN MOTION. GAS PEDAL WILL STICK. SEEMS TO FUNCTION NORMALLY AFTER THE CAR HAS WARMED UP. I TAPPED ON THE GAS PEDAL TO SEE IF IT WOULD UN-STICK AND IT ACCELERATED AT VERY HIGH SPEED AND WAS STUCK UNTIL I PULLED OVER AND TURNED THE CAR OFF. ACCELERATION DROPPED DOWN SLOWLY AFTER I TURNED THE CAR BACK ON AND LEFT IT IN PARK. RESUMED NORMALLY AFTER.

SUDDEN ACCELERATION WHILE IN SLOW TRAFFIC. SEEMED LIKE IT WENT FULL RPM. I HELD THE BRAKES AND PUT IT IN NEUTRAL. RPMS CAME DOWN AND I DRIVE OFF. KINDA SCARY THOUGH. *TR

THIS HAS HAPPENED TO ME 2 TIMES, UPON DRIVING THE CAR IT RANDOMLY ACCELERATES ALL ON ITS OWN. ITS AS IF SOMEONE IS PUTTING THE PEDAL TO THE METAL AND TRYING TO BRAKE AT THE SAME TIME.. SLAMMING ON THE BRAKES ONLY SLOWS IT DOWN BUT NOT ENOUGH THEN I PROCEED TO PULL THE EMERGENCY BRAKE ALL THE WAY WHICH ONLY ASSITS A LITTLE.. SO AT THIS POINT I AM AT THE COMPLETE MERCY OF A VECHICLE WITH A MIND OF ITS OWN.. IM STUCK DRIVING A CAR THAT WONT STOP FOR 3 EXITS IN THE BREAKDOWN LANE AND 2 SECONDS AWAY FROM CALLING THE STATE POLICE FOR ASSISTANCE... PUTTING IT INTO NEUTRAL DIDNT STOP IT EITHER IT KEPT GOING!!! TOOK IT IMMEDIATLY TO THE HYUNDAI DEALERSHIP AND AFTER PUTTING 100 MILES ON IT TO TRY AND RECREATE THE ISSUE ( WHICH THATS A VERY DANGEROUS ISSUE TO RECREATE ) IT DIDNT OCCOR FOR THEM SO I WAS HANDED MY KEYS AND TOLD TO DRIVE OFF IN A POSSIBLE DEATH MACHINE WITH A MIND OF ITS OWN. I TAKE MY CAR FOR THE SCHEDULED MAITINECE AND DO MY PART SO HYUNDAI SHOULD NOT WANT THIER LOYAL CONSUMERS DRIVING SUCH HAZARDS.... IVE READ SEVERAL SIMAILAR STORIES AND PEOPLE HAVE HAD NO LUCK IN GETTING THIS MATTER RESOLVED THIER SOULUTION WAS TO GET A NEW CAR ... IF ONLY IT WAS THAT EASY. *TR

TRAVELING ON INTERSTATE, USING CRUISE CONTROL (AS I HAD THE DAY PREVIOUSLY AND FOR APPROX 150 MILES THIS DAY) ATTEMPTED TO STOP VEHICLE DUE TO VEHICLES SLOWING DOWN IN FRONT OF ME. COULD NOT GET OUT OF CRUISE CONTROL - IN FACT, THE VEHICLE ACCELERATED -- AND BRAKES DID NOT WORK. FORTUNATELY, I WAS IN THE RIGHT LANE AND WAS ABLE TO EXIT THE HIGHWAY WITHOUT HITTING THE GUARDRAIL (APPROX. 20 FEET AWAY WHEN I LEFT THE HIGHWAY), TRAVELED AT A HIGH RATE OF SPEED DOWN A SLIGHT EMBANKMENT AND INTO A FIELD, WHERE FORTUNATELY THERE WERE NO OBSTACLES, AND WAS ABLE TO STOP THE VEHICLE APPROX. 500 FEET FROM LEAVING THE HIGHWAY. THE ENGINE WAS STILL RUNNING, NOW AT A NORMAL RATE. I ATTEMPTED TO RETURN TO THE INTERSTATE BUT WAS NOT SUCCESSFUL DUE TO THE EMBANKMENT. I DROVE THROUGH MY PREVIOUS TRACKS IN THE FIELD AND WAS ABLE TO GET ONTO A NEARBY EXIT RAMP. THE VEHICLE FUNCTIONED NORMALLY AFTER THAT. PLEASE NOTE, THIS VEHICLE HAS A MANUAL TRANSMISSION. I DID NOT ATTEMPT TO ENGAGE THE CLUTCH TO PUT THE TRANSMISSION IN NEUTRAL BECAUSE I HAD BOTH HANDS ON THE STEERING WHEEL TRYING TO MANEUVER THROUGH THE FIELD, WHICH WAS QUITE GREEN, ACTIVELY GROWING, AND APPROXIMATELY 15 INCHES HIGH. THE CROP SCRAPED THE UNDERSIDE OF THE VEHICLE, WHICH IS NOW IN THE SHOP WAITING TO HAVE THE NEW PART REPLACED. THE MECHANIC WILL CHECK FOR DAMAGE ON THE UNDERSIDE. I AM NOT SURE IF THE VEHICLE STOPPED B/C THE BRAKES FINALLY KICKED IN OR THE VEGETATIVE GROWTH SLOWED ME DOWN. *TR

I WAS DRIVING TO WORK, WENT TO PASS A CAR, MY VEHICLE KEPT ACCELERATING. I PULLED BACK INTO THE RIGHT LANE, STEPPING ON THE BRAKES AS THE CAR KEPT GOING FASTER. I STOOD ON THE BRAKES , NO LUCK, PULLED THE EMERGENCY BRAKE, IT SLOWED DOWN A LITTLE, SO I TURNED THE CAR OFF AND COASTED ONTO THE SIDE OF THE ROAD. I TURNED THE CAR ON AGAIN TO PUT IT IN PARK, I HAD TO FIGHT WITH IT AND THE ENGINE WAS JUST SCREAMING. I GOT IT IN PARK AND SHUT IT OFF AGAIN. IT WAS VERY SCAREY TO HAVE NO CONTOL OF THE SPEED. WHEN THE TOW TRUCK CAME THE AR WOULD NOT START AT ALL, HE SAID THE BATTERY WAS DEAD. NOW I'M WAITING TO HEAR FROM THE DEALER. *TR
