2007 Toyota 4runner Electrical Problems

When you turned on the rear defroster in winter conditions, your rear window suddenly shattered and exploded, scattering glass throughout your vehicle and onto the road behind you. This created a dangerous driving situation and exposed passengers to flying glass shards. Toyota has acknowledged this issue in technical bulletins and offers window replacements, but there's no warning before the glass fails.

You discovered a mileage discrepancy on your 2007 Toyota 4Runner after purchase. The odometer showed 87,750 miles when you bought it, but when registering the vehicle, it was found to actually have 200,000 miles. This suggests the odometer may have been tampered with or rolled back before the sale. You may need to consult with a mechanic or attorney about the vehicle's actual service history and potential warranty implications.

Your brake lights are turning on and off randomly or not working when you press the brake pedal, your horn occasionally won't work, and other electrical components are failing intermittently while driving, parked, or idling. A dealer diagnosed a failed ICMU (integrated circuit management unit) that needs replacement. The fix will involve replacing the ICMU module to restore proper electrical function.

TL* THE CONTACT OWNS A 2007 TOYOTA 4RUNNER. AFTER STARTING THE VEHICLE, A HIGH PITCHED AUDIBLE ALARM SOUNDED AND THE ABS, TRACTION CONTROL, AND EMERGENCY BRAKE SENSORS REMAINED ILLUMINATED. ALSO, WHEN DEPRESSING THE BRAKE PEDAL TO STOP THE VEHICLE, THE BRAKES MALFUNCTIONED AND THE PEDAL TRAVELED TO THE FLOORBOARD. THE VEHICLE WAS TOWED TO JIM HUDSON TOYOTA (970 COLUMBIANA DR, IRMO,SC) , BUT THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 111,000.

MY REAR WINDOW SHATTERED AFTER USING THE DEFROSTER. ONCE I GOT OUT OF MY CAR AFTER PARKING IT IN MY JOB'S GARAGE IT BUSTED ON IT'S OWN. I FOUND OUT THAT THIS HAS HAPPENED TO MANY 4TH GENERATION 4RUNNER OWNERS BUT TOYOTA WON'T RECALL OR EXTEND THE WARRANTY FOR THIS ISSUE ANY LONGER. NOW I HAVE TO EITHER NEVER USE MY REAR DEFROSTER AGAIN WHILE LIVING IN COLORADO OR RISK IT SHATTERING AGAIN AND HURTING PASSENGERS IN MY CAR. I WOULD HAVE NEVER BOUGHT THE VEHICLE IF I HAD KNOWLEDGE OF SUCH A DANGEROUS ISSUE.

TL* THE CONTACT OWNS A 2007 TOYOTA 4RUNNER. WHEN THE REAR DEFROSTER WAS ACTIVATED, THE REAR WINDOW FRACTURED. THE VEHICLE WAS TAKEN TO HAMER TOYOTA (11041 SEPULVEDA BLVD, MISSION HILLS, CA 91345, 818-365-9621) WHERE BURNT WIRES WERE FOUND. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 216,800.

I WAS DRIVING ON DEC. 24TH, 2018, TURNED ON MY REAR DEFROSTER ON, AND WITHIN MINUTES MY REAR WINDOW EXPLODED. THE COMPANY, SAFELITE, TOLD ME THAT THE DEFROSTER LOOKED LIKE IT SHORTED OUT AND CAUSED THE DAMAGE. ATTACHED IS A PICTURE OF THE DEFROSTER WIRES.

TL* THE CONTACT OWNS A 2007 TOYOTA 4RUNNER. THE CONTACT STATED THAT THE WIRING HARNESS HAD TO BE REPLACED DUE TO RODENTS EATING THE INSULATION ON THE WIRES. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE INSULATION ON THE WIRES WERE MADE OF RICE HULLS AND ATTRACTED RODENTS. THE WIRES NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE THE FAILURE MILEAGE WAS 50,000. THE VIN WAS NOT AVAILABLE. UPDATED 02/09/17*LJ

THE REAR HATCH DOOR HANDLE IS DEFORMED AND TURNED INTO A TAR-LIKE MESS THAT COVERS OUR FINGERS WHENEVER WE TRY TO OPEN THE REAR HATCH. I HAVE NOTED NUMEROUS OTHER 4-RUNNER OWNERS HAVING THE SAME EXACT MALFUNCTION. PROBLEM IS THE MELTED RUBBER COVER WHICH IS PART OF THE SWITCH ASSEMBLY, PART #84840-35010. TOTALLY UNSAT! *TR

VEHICLE WAS PARKED ON SHOULDER OF ROAD, ENGINE RUNNING, WHILST ADJUSTING THE MOBILE GPS (HENCE THE REASON FOR STOPPING). AT FIRST SMOKE WAS COMING UP AROUND/THROUGH CENTER CONSOLE (BETWEEN DRIVER'S SEAT AND PASSENGER FRONT SEAT) AND THEN FLAMES. THE INTERIOR OF PASSENGER COMPARTMENT WAS TOTALLY BURNED OUT IN SPITE OF PROMPT RESPONSE BY EMERGENCY CREW. STATE FARM INSURANCE HAS NATURALLY BEEN NOTIFIED ALTHOUGH I HARDLY SEE WHY STATE FARM SHOULD PAY AND NOT TOYOTA. SURELY THERE MUST HAVE BEEN SOMETHING WRONG WITH ELECTRICAL WIRING.

THE REAR HATCH DOOR HANDLE TURNED INTO A MELTED RUBBER/PLASTIC MESS. OUR HANDS ARE COVERED WITH BLACK MELTED RUBBER TYPE MATERIAL WHENEVER WE TRY TO OPEN THE REAR HATCH. AFTER ONLINE RESEARCH, I SEE THERE ARE ALLOT OF OTHER TOYOTA 4 RUNNERS WITH THE SAME PROBLEM. THE PART IS CALLED, SWITCH ASSEMBLY, BACK PART #84840-35010. NO DOUBT THAT THE PART IS FAULTY. *TR

MY VEHICLE, 2007 TOYOTA 4RUNNER, HAS BEEN EXPERIENCING SOME ISSUES WHEN THE TEMPERATURE DROPS BELOW FREEZING. LIVING IN MAINE, THIS HAPPENS MORE OFTEN THAN ANY HUMAN WOULD LIKE. IN ANY EVENT, MY HVAC BLOWER MOTOR CONTINUES TO LITERALLY FREEZE UP AND WILL NOT WORK. TOYOTA HAS ISSUED A TSB (AC002-07) ON THIS EXACT ISSUE. SINCE MY VEHICLE IS OUT OF WARRANTY I'M TOLD BY THE LOCAL DEALER AND BY TOYOTA DIRECTLY THAT I NEED TO ASSUME ALL COSTS FOR REPAIR, YET IF THE VEHICLE WAS "IN WARRANTY" THESE REPAIRS WOULD BE COVERED. THE VEHICLE WAS DRIVEN IN WARM CLIMATES FOR THE DURATION OF THE WARRANTY PERIOD AND THIS ISSUE WAS NOT DISCOVERED UNTIL A RECENT MOVE. I'M UNCLEAR HOW THIS ISSUE IS NOT SEEN AS A DIRECT SAFETY ISSUE AND HAS NOT BECOME A STANDARD VEHICLE RECALL FOR REPAIR. THIS IS AN OBVIOUS DESIGN FLAW WITH THE VEHICLE WHICH CAN IMPAIR THE VEHICLE'S ABILITY TO PERFORM SAFELY. I HAVE NOT DRIVEN MY VEHICLE IN OVER A WEEK DUE TO THE FACT THAT IT IS UNSAFE TO DRIVE IN A FREEZING COLD VEHICLE, BUT MORE IMPORTANTLY, I CANNOT GET AIR MOVEMENT TO DEFROST MY WINDSHIELD. WITH NO HEAT, OR THE ABILITY TO DEFROST YOUR WINDSHIELD IN INCLEMENT WEATHER THERE EXISTS AN ABSOLUTE SAFETY ISSUE. ADDITIONALLY, I HAVE A 20 MONTH OLD CHILD AND OPERATING A VEHICLE WITH NO MECHANISM FOR WARMING ITSELF IS IN MY EYES "UNSAFE" THANK YOU FOR YOUR TIME AN CONSIDERATION.

MICE HAVE INFILTRATED THE HEADLINER AREA OF 2007 TOYOTA 4 RUNNER. THEY BUILT A NEST AND CHEWED THE WIRING INSULATION FOR THE SUNROOF SWITCH WHICH CAUSED A SHORT THAT MELTED THE WIRES AND CAUSED THE SUNROOF TO MALFUNCTION. DEALERSHIP REPLACED THE SWITCH AND REPAIRED THE WIRES FOR $360 SINCE THIS WAS NOT COVERED UNDER WARRANTY. AFTER EXPLORING THE INTERNET OTHER PEOPLE ARE EXPERIENCING THE SAME PROBLEMS ON HONDA AND SEVERAL OTHER MODELS. SOME OF THE CONVERSATIONS REFERRED TO THE WIRING INSULATION BEING MADE OUT OF SOY BASED MATERIAL. IS THERE ANY IDEA WHY/HOW ARE THEY PAST THE ENGINE COMPARTMENT AND INTO THE HEADLINERS AND CABINS? COULD THERE BE A DESIGN FLAW? FROM READING THE POSTS A STRONG POSSIBILITY EXISTS FOR ACCIDENTS TO BE CAUSED BECAUSE MICE ARE RUNNING ACROSS PEOPLE'S FEET, ETC. WHILE THEY ARE DRIVING. HEALTH CONCERNS HAVE ALSO BEEN RAISED DUE TO ODORS AND FECES BY THE MICE, SOME OF THESE INFILTRATION SOUND PRETTY BAD ALL OF WHICH CANNOT BE ATTRIBUTED SOLELY TO THE OWNERS. THERE'S NOT MUCH THAT CAN BE DONE TO KEEP THEM OUT OR SO IT SEEMS. *TR
