2007 Subaru Outback Electrical Problems

While you're driving, your airbag warning light comes on and multiple dashboard lights flash simultaneously, causing your cruise control to disconnect. This problem occurs intermittently—it might happen one day but not the next. The issue likely involves an electrical fault affecting the airbag system and related controls, which may require diagnostic testing to pinpoint the underlying cause.

Your airbag warning light is turning on and off intermittently, and you've already replaced the overhead circuit board once before. The solder joints on the circuit board are failing and causing loose electrical connections. When the airbag light is on, your airbags won't deploy in a crash, which is a serious safety risk. Fixing this will likely require replacing the overhead circuit board with a properly manufactured unit.

While driving, your engine continued running but the gas pedal stopped responding—you coasted to the side of the road, shut off the engine, and restarted it to regain pedal control. The check engine light came on after restart, and a diagnostic scan revealed a P2138 code, which points to a throttle or pedal sensor issue. This problem could cause sudden loss of acceleration without warning, creating a serious safety risk in traffic.

Your airbag warning light is staying on constantly, which means your airbags won't deploy in a crash—a serious safety issue. You're also experiencing a failing rear wire harness that controls the rear defroster and other functions. Both repairs are expensive (over $400 for the airbag issue alone, plus $800 for the harness), and you're concerned about potential electrical fires given the apparent quality issues with the electronic components. A technician will need to diagnose and replace the faulty airbag system sensor or module and the rear wire harness assembly.

All your rear lights, brake lights, and rear hatch lock stopped working because the wiring that runs between the car body and the hatch door got cut from repeatedly opening and closing the hatch. This appears to be a common issue affecting 2005-2007 model years. The fix will likely involve replacing the damaged wiring harness and possibly adding protective conduit to prevent the wires from being pinched or cut in the future.

You noticed that four wires near your rear defroster were cut, which affected your windshield wipers, hatch door lock, defroster, and rear stop lights. A mechanic confirmed these wires were damaged, but the vehicle wasn't repaired. Subaru said your VIN wasn't part of any recall for this issue. The repair will likely involve replacing the damaged wires and reconnecting them to restore power to all four affected systems.

WELL I LOST ALL THROTTLE CONTROL FOR THE FIRST TIME. ENGINE LIGHT WAS ON WHICH DISABLED THE VDC AND CRUISE AND THE GAS PEDAL. IT HAS HAPPENED SEVERAL TIMES SINCE THEN. WHEN SHUTTING THE CAR OFF IT IS VERY HARD TO RESTART. WHEN THIS HAPPENS AND YOU TRY TO STOP THE CAR DOESN'T WANT TO IT JUST PULSES FORWARD SO MORE BRAKE PEDAL IS NEEDED. IF YOU PUT IT IN PARK THE ENGINE REVS HIGH. THIS IS A KNOWN ISSUE WITH THE TPS NOT BEING ABLE TO COMMUNICATE WITH THE THROTTLE SERVO VIA THE TCM. THIS ISSUE HAPPENS AT RANDOM. USUALLY WHEN I'VE BEEN DRIVING IT FOR ABOUT 10 MINUTES.

MY 2007 OUTBACK WAGON TAILGATE LIGHTS, LOCK FAILED TO WORK. SOME OF THE WIRING WITHIN THE FLEXIBLE RUBBER CONDUIT BROKE AND SHORTED OUT THE FUSE. THE WIRES COULD NOT ENDURE THE REPEATED MOTION OF THE TAILGATE MOVEMENT. I HAVE NOW LEARNED THAT SEVERAL OTHERS HAVE HAD THE SAME ISSUE. THE UPPER BRAKE LIGHT, REVERSE LIGHTS, TAILGATE LOCK ARE AFFECTED. I BELIEVE THE REAR WIPER MOTOR WIRING IS IN THE SAME HARNESS. A PREVIOUS OWNER MADE A REPAIR OF ONE WIRE AS SEEN IN THE PHOTO. REPAIR DID NOT HOLD UP. SUBARU SHOULD CORRECT THE CONDITION AT NO CHARGE.

AUDIO/HVAC CONTROLS FLASH AND DO NOT RESPOND TO ATTEMPTS TO CHANGE MODES OR CUT OUT ALTOGETHER. PROBLEM STARTED ON A VERY HOT SUMMER DAY FOUR YEARS OR SO AGO. WHEN CONTROLS ARE ACTING UP, NOT ONLY DOES THE PANEL NOT DISPLAY PROPERLY, BUT ALSO FAILS TO RESPOND TO ANY ADJUSTMENTS. NOT BEING ABLE TO ADJUST THE AUDIO OR CLIMATE CONTROL IS AN INCONVENIENCE. HOWEVER, NOT BEING ABLE TO DEFROST FRONT OR REAR WINDOWS WHEN NEEDED IS A SAFETY HAZARD. PROBLEM HAS BEEN REPORTED ON SUBARU FORUMS (FOR EXAMPLE, HTTP://WWW.SUBARUOUTBACK.ORG/FORUMS/80-ELECTRICAL-ELECTRONICS/23909-08-O-B-RADIO-HVAC-CONTROL-LIGHTING-PROB.HTML). PROBLEM HAS OCCURRED BOTH WHILE DRIVING AND IMMEDIATELY AFTER IGNITION. GOES AWAY SOMETIMES ON ITS OWN, SOMETIMES WHEN TURN OFF CAR AND TURN BACK ON, SOMETIMES DOESN'T RESOLVE EVEN WITH RE-IGNITION. HAPPENS ON CITY STREETS AND ON HIGHWAYS BUT I SPEND MORE TIME ON CITY STREETS.

2007 SUBARU OUTBACK. CONSUMER WRITES IN REGARDS TO SERVICE DEPARTMENT REFUSES TO REPAIR/REPLACE VEHICLE RADIO. *SMD THE CONSUMER WAS INFORMED IT WOULD COST $1,00 TO REPLACE THE RADIO. *JB

THIS IS MY SECOND COMPLAINT TO BE FILED. THIS HAS BEEN AN ONGOING PROBLEM SINCE 2013. MY 2007 SUBARU OUTBACK LOSES VEHICLE POWER AS THE ACCELERATOR STOPS RESPONDING. THE CRUISE CONTROL, TRACTION, AND CHECK ENGINE LIGHTS ALL BECOME ILLUMINATED OR FLASHING. THIS IS ESPECIALLY COMMON UPON RESTARTING THE CAR AFTER A SHORT DRIVE, COMING TO A STOP, OR AFTER 5-10 MINUTES FROM A COLD START. RESTARTING THE VEHICLE UNTIL THE VEHICLE WILL NOT RESTART AND THEN RESTARTING ONCE MORE RESETS THE ISSUE FOR APPROXIMATELY 24 HOURS. CLEANING THE CONNECTOR PLUG TO THE ACCELERATOR TEMPORARILY RESOLVES THE ISSUE ANYWHERE FORM 6 MONTHS TO ONE WEEK. SUBARU HAS BEEN CONTACTED AND ISSUED A GENERIC RESPONSE MOSTLY DEALING WITH AIR BAG SAFETY CONCERNS. THIS IS A VERY HAZARDOUS DEFAULT IN THE VEHICLE WHICH IS BEING IGNORED.

TL* THE CONTACT OWNS A 2007 SUBARU OUTBACK. WHILE DRIVING APPROXIMATELY 60 MPH, THE VEHICLE LOST POWER. THE CRUISE CONTROL AND TRACTION LIGHTS ILLUMINATED. THE CONTACT COASTED TO THE SIDE OF THE ROAD AND TURNED OFF THE VEHICLE. THE VEHICLE WAS RESTARTED AFTER A COUPLE OF MINUTES. THE CONTACT DROVE HOME AND CALLED AN INDEPENDENT MECHANIC, WHO WAS UNABLE TO DIAGNOSE THE FAILURE. THE FAILURE RECURRED SEVERAL TIMES. THE FAILURE WAS NOT DIAGNOSED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS NOT PROVIDED. THE FAILURE MILEAGE WAS 249,000.

WIRE HARNESS, THAT PASSES THROUGH RUBBER ARTICULATED GASKET THAT CONNECTS BETWEEN VEHICLE BODY AND REAR HATCH DOOR OF WAGON, SUFFERS FROM WIRE FATIGUE THAT CAUSES INDIVIDUAL WIRE INSULATORS TO CRACK AND CONDUCTING WIRES TO BREAK, LEADING TO FAILURE OF CRITICAL AUTOMOBILE SAFETY EQUIPMENT; NAMELY, REAR WIPER MOTOR, REAR BACK-UP LIGHTS, REAR MIDDLE BRAKE LIGHT, REAR LICENSE PLATE LIGHTS, REAR WINDOW DEFROSTER. THIS DESIGN DEFECT HAS BE REPORTED BY NUMEROUS OWNERS AND HAS BEEN DOCUMENTED ON YOUTUBE (HTTPS://WWW.YOUTUBE.COM/WATCH?V=AMEKPTVGMHS) AND OUTBACK OWNERS' BULLETIN BOARD WEBSITES (HTTP://WWW.SUBARUOUTBACK.ORG/FORUMS/66-PROBLEMS-MAINTENANCE/20718-REAR-WIPER-DOES-NOT-RETURN-PARK-HOME-POSITION.HTML). PROBABLE MANUFACTURING DEFECTS INCLUDE: (I) ORIENTATION OF RUBBER ARTICULATED GASKET THROUGH WHICH REAR DOOR WIRING HARNESS PASSES IS SUCH THAT IT CAUSES UNDUE FLEXING OF WIRE HARNESS WIRES UPON OPEN / CLOSE SEQUENCE OF REAR TAILGATE, AND (2) DEFECTIVE AND/OR UNDERSIZED WIRE HARNESS WIRES UNABLE TO WITHSTAND THE OPEN / CLOSE SEQUENCE OF REAR TAIL GATE.

DASHBOARD AIRBAG LIGHT TURNED ON. AIRBAG SAFETY SYSTEM IS SUBSEQUENTLY DISABLED, EVEN IN THE EVENT OF AN ACCIDENT. SOURCE OF PROBLEM IS TRACED BACK TO INDICATOR LIGHT IN THE OVER HEAD CONSOLE. THE WARNING LIGHTS DO NOT LIGHT UP AS THEY SHOULD. THE PASSENGER SEAT BELT OR OFF LIGHTS DO NOT APPEAR WHEN THEY SHOULD SOMETIMES THEY ARE DIM AND RESOLVE WITH A LIGHT TAP OR CHANGE IN AMBIENT TEMPERATURE. BRIEF INTERNET SEARCH REVEALS THIS IS COMMON AND IS THE RESULT OF FAULTY SOLDER IN THE OVERHEAD CONSOLE. DEALERSHIP ADVISES REPLACE THE ENTIRE CONSOLE AT OWNER EXPENSE. PART COSTS $130, LABOR IS EVEN MORE. I AM NOT AN ELECTRICAL ENGINEER AND HAVE NO IDEA IF SOLDERS SHOULD FAIL AT 8 YEARS. THIS PARTICULAR SOLDER IS AN INTEGRAL PART OF THE AIRBAG SYSTEM AND RENDERS THE VEHICLE UNSAFE TO DRIVE. SUBARU SHOULD REMEDY THIS WITH A RECALL OR AT LEAST REIMBURSE MY COST. I WILL PROVIDE THE DEALERSHIP WITH A COPY OF THIS REPORT.

SEVERAL BROKEN WIRES IN THE PASSENGER SIDE FLEXIBLE JOINT WHERE THE ELECTRICAL WIRING TRAVELS BETWEEN THE REAR CARGO AREA AND THE TAILGATE WERE DISCOVERED. IT APPEARS THAT INFERIOR WIRE INSULATION BECOMES BRITTLE OVER TIME AND LEADS TO BROKEN WIRES. SYMPTOMS WERE THAT THE REAR WINDOW WINDSHIELD WIPER FAILS SPORADICALLY / DOES NOT RETURN TO HOME LOCATION, AND THERE IS NO POWER AT THE LICENSE PLATE LIGHT. WIRING FOR REAR BRAKE LIGHTS AND LOCKS ALSO TRAVEL THROUGH THIS JOINT AND CAN BE AFFECTED. MANY SUBARU OUTBACK OWNERS ARE DISCOVERING THIS ISSUE AND DISCUSSING ONLINE. SINCE THIS CAN AFFECT THE WINDSHIELD WIPER AND THE REAR LIGHTS, THIS IS A SAFETY ISSUE. GIVEN THE NUMBER OF OWNERS DISCOVERING THE ISSUE, THERE SHOULD BE A RECALL ISSUED TO FIX THIS PROBLEM. *TR

HATCH WON'T LOCK, AND BACKUP LIGHTS DON'T WORK. FOUND 2 BROKEN WIRES ON RIGHT SIDE WIRE HARNESS, I HAVE READ LOTS OF OTHER POSTINGS ABOUT THE SAME PROBLEM. *TR

VEHICLE STOPPED AT A RED LIGHT DURING RUSH HOUR. TRIED TO ACCELERATE FOR RIGHT TURN, HOWEVER THERE WAS NO ACCELERATION WHEN THE GAS PEDAL WAS DEPRESSED. CHECKED THE DISPLACE FOR INDICATOR LIGHTS AND CHECK ENGINE LIGHT AND TRACTION CONTROL LIGHTS WERE ON STEADILY WHILE CRUISE CONTROL WAS BLINKING. IMMEDIATELY TURNED OFF HEATER, SEAT HEATER, AND RADIO, AND PROCEEDED TO COAST DOWN A HILL AT IDLE. GAS PEDAL WAS UNRESPONSIVE, BUT I WAS ABLE TO SAFELY PULL OFF THE ROAD AFTER 0.3 MILES. RESTARTED THE CAR TWICE AND THE WARNING LIGHTS WERE STILL ON AND GAS PEDAL STILL DID NOT WORK. A THIRD ATTEMPT TO RESTART RESULTED IN THE ENGINE TURNING OVER BUT NO IGNITION. AFTER SEVERAL MORE RESTARTS THE GAS PEDAL WAS RESPONSIVE BUT INDICATORS LIGHTS WERE STILL PRESENT. DROVE TO AUTO REPAIR SHOP WITH NORMAL SPEED CONTROL WHERE THE INDICATOR LIGHTS PROMPTLY TURNED OFF. SENSOR HISTORY INDICATED P2138 CODE FOR THROTTLE POSITION SENSOR. *TR

WHILE DRIVING OUR 2007 SUBARU OUTBACK SW ON A 6 LANE DIVIDED HIGHWAY AT 65 MPH, THE CAR SUDDENLY DECELERATED AND LOST ALL GAS PEDAL RESPONSE. MY WIFE WAS ABLE TO MOVE THE CAR TO THE SIDE OF THE ROAD ALTHOUGH SHE ALMOST CAUSED AN ACCIDENT DUE TO SURROUNDING TRAFFIC. THE CAR STARTED FLASHING THE CRUISE CONTROL, TRACTION CONTROL, AND CHECK ENGINE DASH LIGHTS. AFTER ALLOWING THE CAR TO SIT FOR A FEW MINUTES, MY WIFE WAS ABLE TO START THE CAR AGAIN AND GET HOME. I CHECKED THE ERROR CODES AND GOT A P02138. I DID SOME RESEARCH AND FOUND NUMEROUS OTHER PEOPLE EXPERIENCING THE SAME ISSUE ON THE SUBARU BLOGS. ALL OF THE OTHER REPORTS POINTED TO THE SAME SOURCE(S) THE GAS PEDAL POSITION SENSOR OR THROTTLE POSITION SENSOR. MOST REPORTED SUBARU SERVICE DEPARTMENTS CLAIMING NO KNOWLEDGE OF THE ISSUE EVER HAPPENING BEFORE. BOTH MY WIFE AND I HAVE HAD THE SAME THING HAPPEN SEVERAL TIMES SINCE IN BOTH LOCAL AND HIGHWAY TRAFFIC. I HAVE CLEANED THE TERMINALS ON BOTH SENSORS AND THIS SEEMS TO HELP, BUT THE PROBLEM ALWAYS RETURNS. I READ WHERE SEVERAL OTHER DRIVERS HAD THE GAS PEDAL ASSEMBLY CHANGED AND THE ISSUE SEEMED TO BE RESOLVED. THIS SEEMS TO BE A SEVERE SAFETY ISSUE. HAVING A CAR SUDDENLY BECOME DEAD ON THE ROAD IN THE MIDDLE OF TRAFFIC IS DANGEROUS TO ANYONE AROUND. *TR *JS

THE 2007 SUBARU OUTBACK (MANUAL) PULSATES AND SURGES WHEN DRIVING ON FLAT SURFACES OR WHEN GOING DOWNHILL AND WHILE LIGHTLY PUSHING ON THE ACCELERATOR. CONCERN EXISTS FOR WHEN DRIVING ON WET OR ICE/SNOW PACKED ROADS AND THE VEHICLE SURGES WITH THE POTENTIAL TO THROW IT INTO A SPIN OR OTHERWISE OUT-OF-CONTROL. MANUFACTURER HAS INDICATED IT IS AN INHERENT CHARACTERISTIC OF THE VEHICLE WITH NO FIXES AVAILABLE, ALTHOUGH THEY HAVE A QUALITY MONITORING REPORT IN PLACE TO HOPEFULLY IMPROVE IN FUTURE YEARS. *TR
