2006 Subaru Legacy Speed Control & Cruise Problems

TL* THE CONTACT OWNS A 2006 SUBARU LEGACY OUTBACK. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 35 MPH, THE ACCELERATOR PEDAL WAS DEPRESSED TO THE FLOORBOARD HOWEVER, THE VEHICLE FAILED TO RESPOND. THE VEHICLE WAS NOT TAKEN TO BE DIAGNOSED NOR REPAIRED. NEITHER THE DEALER NOR THE MANUFACTURER WERE CONTACTED NOR NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 125,000. THE VIN WAS NOT AVAILABLE.

WHILE DRIVING IN TRAFFIC ALL OF A SUDDEN THE GAS PEDAL STOPS WORKING, THE CHECK ENGINE LIGHT ILLUMINATES THE CRUISE CONTROL LIGHT ILLUMINATES BUT THE PEDAL HAS NO EFFECT ON THE ENGINE THE CAR SLOWS VERY QUICKLY AND COMES CLOSE TO CAUSING AN ACCIDENT. I HAVE CHECKED FORUMS ON THE WEB AND FOUND WHERE MANY OTHERS HAVE HAD SAME ISSUES. THE FORUM IS SUBARUOUTBACK.ORG PLEASE CHECK THIS SIGHT THE CODE IS P2138 ANY HELP WILL BE APPRECIATED

CAR WOULD NOT ACCELERATE UPON ENTERING THE HIGHWAY AFTER PUSHING ON THE GAS PEDAL THE CAR WOULDN'T DO ANYTHING . I WAS ABLE TO GET OFF TO THE SIDE AND MISSED BEING HIT FROM BEHIND FROM ON COMING TRAFFIC...I NOTICE CHECK ENGINE LIGHT AND FLASHING CRUSE CONTROL LIGHT... SECOND TIME SOME WEEKS LATER IT DID THE SAME THING THIS IS VERY DANGEROUS BECAUSE YOU NEVER KNOW WHEN THIS WILL HAPPEN.

WHILE DRIVING, THE CHECK ENGINE LIGHT COMES ON AND THERE IS NO POWER TO THE GAS PEDAL. THE CAR IS UNABLE TO ACCELERATE OR MAINTAIN SPEED AND THE DRIVER NEEDS TO AVOID POTENTIAL COLLISIONS BY PULLING OVER ON THE ROAD OR FREEWAY.

TRAVEL POSITION SENSOR FAILS WHEN DRIVING CAUSING DRIVER TO LOOSE CONTROL OF THE VEHICLE. THE ACCELERATOR STOPS RESPONDING, THE CAR GOES INTO FAIL SAFE MODE IGNORES ALL INPUTS FROM DRIVER. THE CAR MAY COAST AT ABOUT 15MPH. THIS COULD HAPPEN WHEN MAKING A LEFT TURN OR ON THE HIGHWAY AT HIGH SPEEDS.

TL* THE CONTACT OWNS A 2006 SUBARU LEGACY. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE LOST ACCELERATION AND THE CHECK ENGINE AND CRUISE CONTROL WARNING INDICATORS ILLUMINATED. THE CONTACT COASTED TO THE SIDE OF THE ROAD. THE VEHICLE WAS TOWED TO THE CONTACT'S RESIDENCE. THE VEHICLE WAS TAKEN TO THE DEALER, BUT THE TECHNICIAN COULD NOT FIND A CODE TO IDENTIFY THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 80,000.

DRIVING AT 55 MPH VEHICLE ACCELERATOR BECAME UNRESPONSIVE. CHECK ENGINE LIGHT CAME ON AS WELL AS CRUISE AND SPORT LIGHTS. THERE WAS NO POWER AT THE PEDAL. I HAD TO COAST TO A STOP IN TRAFFIC LANE. ENGINE SURGED UP AND DOWN IN RPM'S. SHUT KEY CAR OFF. AFTER A COUPLE MINUTES, CAR STARTED AND DRIVING WAS RESUMED LIKE NOTHING HAPPENED. WARNING LIGHTS REMAINED ON IN DASH. *TR

IVE HAD A ON GOING ISSUE WITH MY TPS I PRESS THE GAS AND NOTHING HAPPENS I'VE ALMOST GOTTEN INTO MULTIPLE ACCIDENTS FROM IT HAPPENING IN THE MIDDLE OF A ROAD/INTERSECTION EVEN ALMOST GOT ARRESTED DUE TO IT HAPPENING AT AN AIR PORT

ONE MORNING AFTER STARTING MY CAR I NOTICED THE CHECK ENGINE LIGHT WAS ON. AS I DECIDED TO DRIVE THE CAR DOWN TO A LOCAL MECHANIC, I NOTICED THAT I HAD NO ACCELERATION POWER. THE CAR WAS ON, ENGINE WAS RUNNING, BUT WHENEVER I PUSHED THE GAS PEDAL NOTHING HAPPENED. THE CAR WOULD IDLE HIGH AND COAST WHEN PUT IN DRIVE OR REVERSE, BUT WOULD NOT ACCELERATE AS I PUSHED THE PEDAL. THERE HAVE BEEN NUMEROUS COUNTS OF THIS HAPPENING TO PEOPLE ACROSS THE COUNTRY. LUCKILY I WASN'T ON THE FREEWAY WHEN THIS HAPPENED.

WHILE DRIVING THE CHECK ENGINE LIGHT SUDDENLY CAME ON AND THE GAS PEDAL STOPPED BEING RESPONSIVE. LUCKILY I WAS ABLE TO GET TO THE SIDE OF THE ROAD AND PUT THE VEHICLE IN PARK. WHEN IN PARK THE ENGINE REVVED TO ABOUT 2.5K RPM AND STAYED THERE. I SHUT OFF THE VEHICLE AND RESTARTED IT AND IT STAYED AT THAT LEVEL. AFTER SEVERAL MORE TRIES IT EVENTUALLY STARTED UP AND RAN FINE. THE CHECK ENGINE LIGHT CODE IS P2138 FOR THE THROTTLE POSITION SENSOR.

TL* THE CONTACT OWNS A 2006 SUBARU LEGACY. THE CONTACT STATED THAT THE VEHICLE WOULD NOT ACCELERATE WHEN THE ACCELERATOR PEDAL WAS DEPRESSED. IN ADDITION, THE CHECK ENGINE AND THE CRUISE CONTROL WARNING LIGHTS REMAINED ILLUMINATED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 140,000. THE VIN WAS NOT AVAILABLE.

I EXPERIENCED TWO ISSUES WITH THE ELECTRONIC THROTTLE POSITION SENSOR IN MY 2006 SUBARU LEGACY. THE FIRST TIME I WAS TRAVELING AT APPROX. 35 MPH AND THE RPM'S BEGAN INCREASING RAPIDLY. I WAS IN TRAFFIC AND UNABLE TO PULL OFF TO THE SIDE SAFELY WHEN THE ENGINE COMPLETELY STALLED. I SAT THERE THINKING THAT THE MOTOR WAS GOING TO BLOW UP IF I ATTEMPTED TO START IT AGAIN. I CALLED MY MECHANIC AND HE THOUGHT THAT IT COULD BE THE THROTTLE POSITION SENSOR, AS HE HAS REPLACED MANY OF THEM ON SUBARUS. I WAS ABLE TO START THE CAR AND MOVE OFF TO THE SIDE OF THE ROAD TO MAKE SURE THAT IT WAS NOT GOING TO DO IT AGAIN. THE CAR WAS THEN TAKEN TO THE MECHANIC WHERE HE CLEANED THE SENSOR AND SAID IF I HAVE A PROBLEM AGAIN THEN I SHOULD REPLACE IT. FAST FORWARD 4 MONTHS LATER AND I EXPERIENCED THE SAME PROBLEM ON A BUSY STREET WHERE THE CAR LOST POWER AND COMPLETELY SHUT DOWN AFTER RPMS SKYROCKETED AND I WAS LEFT WITH NO CONTROL. UPON START UP, THE CHECK ENGINE LIGHT CAME ON, OBVIOUSLY TRIGGERING A CODE THAT SAYS THE CAR IS A DEATH TRAP WITH A REALLY POORLY DESIGNED THROTTLE. I PLAN TO HAVE THE PART REPLACED IMMEDIATELY, BUT THIS COULD BE A SERIOUS SAFETY ISSUE FOR SOMEONE NOT IN A POSITION TO MOVE TO THE SIDE OF THE ROAD, AS IT JUST HAPPENS RANDOMLY WITH NO WARNING SIGNS.

I WAS DRIVING ABOUT 40 MPH WHEN I REALIZED THAT I HAD NO CONTROL OF THE PEDAL/GAS. WHEN I LOOKED AT THE DASH BOARD THE CHECK ENGINE LIGHT WAS ON AND THE CRUISE CONTROL LIGHT WAS FLASHING. I HAD TO PULL OVER AND WHEN I PUT THE CAR IN PARK THE VEHICLE REVVED HIGH. IT TOOK ABOUT 15 MINUTES BEFORE THE CAR RESTARTED. I WAS ABLE TO DRIVE HOME. THE DIAGNOSTIC MACHINE INDICATED THAT IT WAS THE THROTTLE PEDAL POSITION SENSOR.CODE P2138. THE THROTTLE BODY WAS REPLACED. I AM STILL HAVING THE SAME ISSUES. *TR

TL* THE CONTACT OWNS A 2006 SUBARU LEGACY. THE CONTACT STATED THAT THE VEHICLE ABNORMALLY ACCELERATED WHILE THE BRAKES WERE ENGAGED AT A COMPLETE STOP. THE CONTACT WAS ABLE TO RESTART THE VEHICLE WITH THE ILLUMINATION OF THE CHECK ENGINE WARNING LIGHT. THE VEHICLE WAS TAKEN INTO A LOCAL DEALER WHERE THE TECHNICIAN DIAGNOSED THAT THE THROTTLE POSITION SENSOR HAD FAILED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 129,000 AND THE CURRENT MILEAGE WAS 129,000.

TAPPED BRAKE PEDAL TO DISABLE CRUISE CONTROL. NO THROTTLE CONTROL WHEN RESUMING MANUAL SPEED CONTROL. COASTED TO A STOP THROUGH MULTIPLE LANES OF FREEWAY TRAFFIC. ENGINE KEPT RUNNING POSSIBLY AT RAISE IDLE SPEED WHEN STOPPED. NO LOSS OF POWER STEERING OR BRAKES.TURNED KEY OFF. RESTARTED AFTER MAYBE LESS THAN A MINUTE. THROTTLE CONTROL RESUMED. CHECK ENGINE LIGHT WAS ON. DROVE TO MULTIPLE LOCATIONS TO GET CODES READ. AFTER 2 OR 3 RESTARTS CHECK ENGINE LIGHT WENT OUT. FOUND A SHOP TO READ CODES. CODE P2138 IN MEMORY. HAVE REMOVED THROTTLE PEDAL ASSEMBLY AND TESTED POSITION SENSOR RESISTANCE VALUES. SOME READINGS MAY APPEAR TO BE SLIGHTLY OUT OF RANGE INDICATED IN SERVICE MANUAL. INTEND TO RECHECK READINGS AND POSSIBLY REPLACE PEDAL ASSEMBLY. MAY ALSO CHECK HARNESS RESISTANCE AND/OR CONSULT DEALER. MILEAGE REPORTED IS APPROXIMATE. *TR

DRIVING AT 35MPH I PRESSED THE GAS PEDAL TO ACCELERATE TO GO UP A HILL AND NOTHING HAPPENED. STEERING BECAME VERY TIGHT. HAD TO COAST TO THE SIDE OF THE ROAD. SHUT CAR OFF AND WAITED THEN TURNED BACK ON. HAS HAPPENED 1 OTHER TIME SINCE FIRST INCIDENT, WITH NO WARNING OR INDICATION. RESEARCHED ONLINE TO FIND THIS IS A COMMON PROBLEM WITH MY VEHICLE'S THROTTLE/PEDAL POSITION SWITCH. HAD I BEEN ON A MORE BUSY STREET OR ON A HIGHWAY WHEN THIS OCCURRED, NUMEROUS VEHICLES MAY HAVE BEEN EFFECTED. *TR

I WAS DRIVING IN THE LEFT LANE OF THE HIGHWAY DURING RUSH HOUR WHEN THE ACCELERATOR STOPPED RESPONDING. I WOULD PUSH THE GAS PEDAL AND NOTHING WOULD HAPPEN. THE ENGINE SEEMED TO BE RUNNING NOMINALLY (IDLING, SINCE THE ACCELERATOR WASN'T WORKING). NO UNUSUAL SOUNDS, NO JERKING, NOTHING. THEN THE CHECK ENGINE LIGHT CAME ON. I MANAGED TO GET ACROSS THE LANES OF TRAFFIC COASTING AND ROLLED SLOWLY INTO A GAS STATION. I TURNED THE CAR OFF AND TURNED IT BACK ON AND EVERYTHING WORKED FINE AGAIN. I FINISHED DRIVING TO WORK WITHOUT INCIDENT. I WENT AFTER WORK AND HAD THE CHECK ENGINE CODE READ. IT WAS A STORED CODE (NO LONGER ACTIVELY FAULTED) OF P2138 WHICH IS A THROTTLE POSITION SENSOR ERROR. I'VE BEEN READING ONLINE AND THIS APPEARS TO BE VERY COMMON AND AN ONGOING PROBLEM FOR LOTS OF PEOPLE. IT IS INCREDIBLY DANGEROUS TO NOT BE ABLE TO CONTROL YOUR CAR RANDOMLY IN THE MIDDLE OF THE ROAD. HOPEFULLY YOU CAN HELP MAKE SUBARU FIX THIS SAFETY ISSUE. *TR
