2006 Hyundai Elantra Cruise Control Problems

HAD BEEN EXPERIENCING ROUGH IDLE DESPITE FUEL SYSTEM CLEANER AND CLEAN THROTTLE BODY. REMOVED AND CLEANED IDLE AIR CONTROL VALVE WITH THROTTLE BODY CLEANER, WHICH SMOOTHED OUT ROUGH IDLE BUT STUCK THROTTLE AT HIGH AND INCREASING RPM (GETTING LOUDER) IN PARK GEAR WHEN PARKING AFTER DRIVING. SUSPECTED AND REPLACED THROTTLE POSITION SENSOR BUT IT WAS ELECTRONIC, NOT SPRING ACTIVATED, AND CONTINUED TO EXPERIENCE SAME HIGH RPMS BEFORE PARKING. WAS DRIVING ON 50 MPH HIGHWAY WITH TRAFFIC LIGHTS (RT. 50 IN VIRGINIA), CAME TO A RED LIGHT AND COULD NOT STOP CAR---RPMS INCREASED WHILE IN DRIVE GEAR DESPITE BRAKES BEING ALL THE WAY TO FLOOR. WOULD HAVE RUN THROUGH RED LIGHT AT HIGH SPEED IF HAD NOT SHUT OFF ENGINE BEFORE INTERSECTION. REPLACED WITH NEW AFTERMARKET IAC (IDLE AIR CONTROL VALVE) AND HAVE HAD NO PROBLEMS SINCE.

TL* THE CONTACT OWNS A 2006 HYUNDAI ELANTRA. THE CONTACT STATED THAT WHILE ATTEMPTING TO PARK, THE VEHICLE INDEPENDENTLY ACCELERATED. THE CONTACT ABRUPTLY DEPRESSED THE BRAKES HOWEVER, THE VEHICLE LUNGED FORWARD AND CRASHED INTO THE LEG OF A PEDESTRIAN. THE CONTACT QUICKLY SHIFTED INTO REVERSE AND THEN BACK INTO DRIVE, AND THE VEHICLE LUNGED FORWARD AGAIN AND CRASHING INTO THE PEDESTRIAN A SECOND TIME. THE PEDESTRIAN SUSTAINED A BRUISED LEG AND SWELLING OF THE LEG AND ANKLE. A POLICE REPORT WAS NOT FILED. NEITHER THE DEALER NOR THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 27,000. UPDATED 07/16/14 MA

WHILE APPLYING THE BRAKES, THE CRUISE CONTROL DOES NOT DISENGAGE. I EXPERIENCED THIS AS THE CAR "LURCHING" FORWARD WHEN BRAKING, AS THE ENGINE IS TRYING TO BRING THE CAR BACK UP TO THE PRE-SET SPEED. THIS HAPPENED, MOST RECENTLY, WHILE ON THE FREEWAY IN RUSH HOUR TRAFFIC. THE SUDDEN LURCH WAS FRIGHTENING SINCE IT WAS UNEXPECTED. THE LURCH ALMOST CAUSED ME TO MAKE CONTACT WITH CAR AHEAD OF ME. LUCKILY THERE WAS NO ACCIDENT. EVEN WITH MULTIPLE PRESSES OF THE BRAKE THE CRUISE CONTROL DID NOT DISENGAGE. IT WAS ONLY BY USING THE HAND CONTROLS WAS I ABLE TO TURN OFF THE CRUISE CONTROL. THIS HAS HAPPENED AT LEAST 2 TIMES, BUT UNFORTUNATELY, I CANNOT RECREATE THE PROBLEM SYSTEMATICALLY. *TR

2006 HYUNDAI ELANTRA. CONSUMER WRITES IN REGARDS TO ACCELERATION MALFUNCTION. *SMD THE CONSUMER STATED AS SHE WAS SLOWLY PULLING INTO AN EMPTY SPACE AT A PUBLIC GARAGE, THE VEHICLE SUDDENLY ACCELERATED FOR NO REASON. THE CONSUMER CRASHED INTO A STONE WALL AND THE AIR BAG DEPLOYED. THE CONSUMER RECEIVED CONTUSIONS TO HER LEGS. THE VEHICLE WAS TOTALED BY HER INSURANCE COMPANY.

ON THE AFTERNOON OF 2/19/2011, WAS DRIVING ABOVE VEHICLE. WHILE ADJUSTING INTO A PARKING SPACE (GOING VERY SLOWLY), CAR SUDDENLY ACCELERATED TO TOP SPEED (140 MPH?) I THEN ATTEMPTED TO STOP CAR BY DRIVING ON THE NEAREST SIDEWALK TO AVOID HITTING CARS ON STREET. AT THIS TOP SPEED I CRASHED INTO A CHAIN LINK FENCE TEARING IT DOWN AND THEN TURNED AND FINALLY STOPPED BY HITTING A TREE. MY AIR BAGS DEPLOYED BUT CAR WAS TOTALED AND I WAS TAKEN TO A NEARBY HOSPITAL IN NORTHEAST PHILA. WITH SEVERE INJURIES. MY RIGHT ARM WAS BROKEN IN TWO PLACES REQUIRING SURGERY AND MY RIBS WERE SEVERELY DAMAGED. BOTH LEGS WERE EXTREMELY BRUISED. I SPENT TWO WEEKS IN TWO PHILA. AREA HOSPITALS AND THEN A MONTH IN A NURSING HOME IN WARMINSTER, PA. UNTIL I WAS ABLE TO WALK WITHOUT ASSISTANCE. AM STILL REQUIRED TO USE A CANE. *TR

MY 2006 ELANTRA HATCHBACK HAS A SUDDEN ACCELERATION PROBLEM. I EXPERIENCED SEVERAL TIMES THAT MY CAR SUDDENLY ACCELERATED WHILE NORMAL DRIVING, FOR EXAMPLE, I WAS DRIVING AT 40 MPH BUT THE CAR SUDDEN LY ACCELERATED TO 60 MPH. ON 1/25/2010, I WAS DRIVING HOME AT 2:30 AM, SETTING THE CRUISE AT 70 MPH AND THE ENGINE SPEED WAS SHOWING THE ENGINE WAS ABOUT 2750 RPM BUT IT SUDDENLY ACCELERATED TO 4000 RPM AND THE CAR WAS HARD TO CONTROL IF I WAS NOT PAYING ATTENTION TO IT. I TURNED OFF THE CRUISE SETTING AT ONCE, LATER I TURNED ON THE CRUISE AGAIN TO SET AT 70 MPH AND LATER IT SUDDENLY ACCELERATED FROM 2750 RPM TO 4000 RPM AND THEN SLOWED DOWN BACK TO 3000 RPM AND AGAIN ACCELERATED TO 4000 RPM THEN BACK TO NORMAL SPEED AT 2750 RPM. ALSO, MY CAR COULD NOT GO FORWARD STRAIGHTLY, IT ALWAYS GOES TO THE LEFT SIDE. I HAVE TO TURN MY STEERING WHEEL TO THE RIGHT IN ORDER TO GO STRAIGHTLY. *TR
