2007 TOYOTA HIGHLANDER Electrical System Problems

2007 HYBRID ABS BRAKE ACTUATOR PROBLEM. THE PRIMER MOTOR CONTINUES TO RUN TO PRIME THE PUMP EVEN WHEN CAR IF OFF. THE HUMMING NOISE CHANGES WHEN YOU PRESS ON THE BRAKES TO LOAD KNOCKING GROANING NOISES. NO DASH WARNING SIGNS. I BOUGHT THIS CAR USED AND IT HAS ALWAYS MADE THE HUMMING NOISE SINCE I BOUGHT IT. I THOUGHT THIS WAS NORMAL FOR A HYBRID. SOMETIMES BRAKE PEDAL WOULD PUSH EASILY TO FLOOR, BUT THEN GET TIGHTER. I WOULD HEAR THE KNOCKING GRINDING NOISE. NO WARNING LIGHTS, HAD BRAKES CHECKED AND THEY ARE GOOD. THOUGHT MAYBE AIR IN LINE. THIS NOISE AND LOOSE PEDAL STARTED ABOUT 1 YEAR AGO. 6/2024 IT DID NOT HAPPEN ALL THE TIME. I ALSO HAVE A COMPANY CAR, SO I DO NOT DRIVE THE TOYOTA HIGHLANDER THAT OFTEN. NOW I CANNOT DRIVE IT AT ALL. FOR FEAR THAT THE BRAKES WOULD GO OUT. I STARTED...

Subject: Urgent Safety Concern - Recurring Issues with Toyota Highlander Hybrid Models Dear National Highway Traffic Safety Administration, We owned the car since almost new, after repeated attempts with Toyota, like others 300K customers from their own site, I am writing to file a formal complaint regarding persistent safety issues with Toyota Highlander Hybrid models, specifically between the years 2004 and 2007. Despite previous reports and numerous attempts to seek assistance from Toyota, the response has been unsatisfactory, with the company deflecting responsibility rather than providing a resolution. **Vehicle Information:** - Make: Toyota - Model: Highlander Hybrid - Year: 2007 - VIN: [XXX] **Description of the Issue:** 1) The primary concerns involve the hybrid a) BRAKE actuators failing/loosing braking power 2) the electrical inverters, which have shown a pattern of failure across many vehicles, including my own. 3) Leaky blow back from engine into intake. 4) Seat belts are not...

STARTS WITHOUT USING A KEY AND CANNOT BE SHUT OFF.

WARNING LIGHT - POSSIBLE INVERTER MALFUNCTION. JUST APPEARED FOR THE FIRST TIME.

HORN STOPPED WORKING, IN MOTION, ON A CITY STREET WHILE TURNING.

TL* THE CONTACT OWNED A 2007 TOYOTA HIGHLANDER. AFTER THE CONTACT RETURNED HOME AND PARKED THE VEHICLE, THE HORN STARTED TO BEEP. THE CONTACT WALKED OUTSIDE AND OBSERVED SPARKS UNDER THE VEHICLE. THE CONTACT ATTEMPTED TO EXTINGUISH THE FIRE WITH THE HOSE, BUT THE VEHICLE BECAME ENGULFED IN FLAMES. A FIRE REPORT WAS FILED. THE FIRE DEPARTMENT EXTINGUISHED THE FIRE. NO INJURIES WERE SUSTAINED. THE VEHICLE WAS DESTROYED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 152,000.

HAZARDOUS SAFETY ISSUE. POSSIBLE MANUFACTURER DEFECT TO ELECTRICAL SYSTEM ON 2001-2007 TOYOTA HIGHLANDERS. WHILE DRIVING AT HIGH OR LOW RATE OF SPEED, THERE HAS BEEN MANY CLOSE CALLS OF BEING HIT FROM BEHIND DUE TO THE MANUFACTURER DEFECT TO THEIR ELECTRICAL COMPONENTS OR WIRING IN SPECIFIC TO REAR BRAKING LIGHTS. WHEN DEPRESSING THE BRAKE PEDAL THE REAR PASSENGER BRAKE LIGHTS DO NOT COME ON. LIGHT BULBS CHANGED, FUSE WAS CHECKED AND CONNECTORS CHECKED. THERE HAS BEEN MULTIPLE IDENTICAL RELATED ISSUES REPORTED BY CONSUMERS ON MANY BLOGS AND FORUMS ONLINE. ONLY REMEDY MENTIONED WAS TO HAVE THE TOYOTA DEALER TO REPLACE THE ELECTRICAL BRAKING COMPONENT OR CIRCUITRY. THIS SHOULD BE A RECALL FOR THE TOYOTA HIGHLANDER 2001-2007 ON THE CRITICAL BRAKING SYSTEMS ON THESE VEHICLES. WHY DO CONSUMERS HAVE TO PAY UPWARDS OF $400 TO REPLACE WHAT APPEARS TO BE A MANUFACTURER ISSUE. THIS IS A ACCIDENT MADE TO HAPPEN. ALSO...

ON MY 2007 TOYOTA HIGH LANDER THE HORN HAS STOPPED WORKING I HAVE NO HORN , WHEN I PRESS THE HORN BUTTON IT DOES NOT SOUND THE HORN. I TOOK IT TO THE DEALER AND THEY CHECK THE HORN AND THE DEALER SAID IT WAS WORKING AFTER I LEFT THE DEALER IT DID NOT WORK , I ASKEDTHE SERVICE ADVISER AND HE SAID ITS AN INTERMITTENT PROBLEM, , THE HORN STILL DOES NOT WORK I STILL HAVE NO WORKING HORN, SOMETHING IS GROUNDING OUT IN THE STEERING COLUMN. I STILL HAVE NO WORKING HORN AND THE DEALER CANT FIND THE PROBLEM.

I WAS DRIVING AND WITHOUT ANY WARNING THE CAR SHUTDOWN DOWN, THE CAR CONTROLS WOULD NOT RESPOND. THE CAR CONTINUED TILL IT LOST MOMENTUM STOPPED, THERE WAS NO/OR VERY LITTLE BRAKING AND STEERING ASSISTANCE/CONTROL. ***I CALLED TOYOTA AND REPORTED THE PROBLEM, NO ASSISTANCE WAS PROVIDED*** THE DASHBOARD FLASHED LIGHTS, THE VSC, AWD AND OTHER LIGHTS CAME ON. FYI - THE CAR HAS BEEN REGULARLY MAINTAINED. THERE ARE NUMEROUS CONTROLS ON THESE SIMILAR ISSUES, VSC AWD ECU ETC, BUT THERE SEEMS TO BE NO ACKNOWLEDGEMENT FROM TOYOTA. *TR

DURING DRIVING, ABRUPTLY WITHOUT WARNING - THE HIGHLANDER HYBRID DURING DRIVING, WITHOUT WARNING, JUST WENT DEAD - CAR DID NOT RESPOND TO DRIVER CONTROL. THE DASHBOARD STARTED FLASHING LIGHTS AND THE VSC CHECK, AWD CHECK, SKID LIGHT, BRAKE LIGHTS CAME ON. THE CAR, AND POWER STEERING STOPPED RESPONDING TO CONTROL. UPON CONTACTING THE DEALERS, EVERYONE HAS GIVEN US A DIFFERENT REASON, SOME DON'T EVEN MAKE SENSE. *TR

THIS IS IN FOLLOW-UP TO MY COMPLAINT #10306258 FILED EARLIER THIS MORNING (FEB 5, 2010). I FOUND MY PREVIOUS SERVICE ORDER OF JULY 23, 2008, FROM MY TOYOTA DEALERSHIP, ON WHICH I COMPLAINED ABOUT THE DELAYED ACCELERATION WHEN I PRESSED ON THE GAS PEDAL. THEIR RESPONSE, AS DOCUMENTED ON MY REPAIR ORDER WAS 'SCANNED FOR ERROR CODES. NONE PRESENT. CHARACTERISTIC OF THIS TRANSMISSION.' ON MY PREVIOUS REPORT TO YOU REGARDING THIS, I CLASSIFIED THIS AS 'FUEL SYSTEM, GASOLINE' AND AS 'ELECTRICAL SYSTEM,' IT LOOKS LIKE TOYOTA CLASSIFIED THIS AS A TRANSMISSION PROBLEM. REGARDLESS, THE FACTS ARE AS I STATED THEM AND I STILL VIEW THIS TO BE A DANGEROUS CONDITION. FOR THE RECORD, MY VEHICLE WAS SERVICED ON JULY 23, 2008 AT WEST ASHLEY TOYOTA, 2100 SAVANNAH HWY, CHARLESTON, SC 29414. THEIR PHONE NUMBER IS 843-556-9110. MY CUSTOMER NBR IS 82921. MY CONCERN WAS ADDRESSED ON THEIR INVOICE # TOCS178222....

TL-WHILE PULLING INTO A PARKING SPACE, THE VEHICLE SUDDENLY ACCELERATED. THE VEHICLE JUMPED THE MEDIAN AND HIT ANOTHER VEHICLE IN ANOTHER PARKING SPACE. THE FAILURE MILES ARE NOT AVAILABLE. THE CURRENT MILES ARE 45,000 MILES. AA

WHEN TRAVELING DOWN HILL FOR EXTENDED PERIODS OF TIME THE BATTERIES CHARGE AND THEN START TO EMIT NOXIOUS FUMES INTO THE CAB OF THE VEHICLE. (OZONE I THINK.) ON SEVERAL OCCASIONS WE HAVE HAD TO ROLL THE WINDOWS DOWN OR STOP AND EXIT THE VEHICLE TO ALLOW THE FUMES TO CLEAR. THE LOCAL DEALER SAYS THAT THERE IS NOTHING WRONG WITH THE VEHICLE, AND THAT THERE IS NOTHING THEY CAN DO ABOUT OUR COMPLAINTS. *TR

WAS PULLING INTO PARKING SPACE UNDER 5 MPH AND THERE WAS A SUDDEN SURGE FORWARD AND THE BRAKES DID NOT WORK. WENT OVER CURB THROUGH BUSHES OFF ANOTHER CURB HITTING UNDERNEATH OF CAR AND BRAKES THEN WORKED AGAIN. CAR WAS TOWED TO DEALER WHERE THEY DROVE IT PUT IT ON A MACHINE AND FOUND NOTHING WRONG WITH THE CAR! *JB

HYBRID INVERTER FAILURE. *NM
