2003 TOYOTA HIGHLANDER Complaints

HEAD GASKET BOLTS STRIPPED OUT CAUSING COOLANT TO LEAK AND LOSS OF CYLINDER COMPRESSION. THIS OCCURRED ON A TOYOTA 2.4 LITER ENGINE. THIS IS A COMMON FAILURE MODE ON THESE ENGINES DUE TO A DESIGN DEFECT. THE THREAD FATIGUES AT THE INTAKE SIDE OF THE ENGINE BECAUSE THE MANIFOLD IS PLASTIC AND THERE IS A RUBBER INSULATOR BETWEEN THE MANIFOLD AND BLOCK WHICH TRAPS THE HEAT IN THAT PART OF THE BLOCK AND FATIGUES THE ALUMINUM THREADS ON THE HEAD BOLTS. THIS HAPPENS ON MANY MODELS FROM 2001-2006 THAT UTILIZE THE TOYOTA 2.4 LITER ALUMINUM ENGINE. THIS IS A $2,500-$5,000 REPAIR. TOYOTA HAS ISSUED A SERVICE BULLETIN ON THIS. I BELIEVE THEY SHOULD HAVE SOME RESPONSIBILITY IN FIXING THIS DESIGN PROBLEM. ENGINES SHOULDN'T FAIL AT 100,000 MILES WITHOUT CAUSE SUCH AS OVERLOADING OR ABUSE. I DON'T HAVE A TOW PACKAGE AND HAVE GARAGED THIS VEHICLE. THERE WAS NO CAUSE AND EFFECT. THIS FAILURE I'VE COME TO LEARN IS COMMON FOR THIS ENGINE. *TR

CYLINDER HEAD BOLTS SEPARATED FROM LOWER ENGINE BLOCK CAUSING A MAJOR COOLANT LEAK (ENG:2AZ-FE) HAD TO REPLACE ENGINE WITH A REMANUFACTURED ENGINE ONLY TO HAVE SAME PROBLEM AGAIN FORCING ME TO ONCE AGAIN REPLACE ENGINE WITH A REMANUFACTURED ENGINE AND THEIRS 22 COMPLAINTS ON CAR COMPLAINTS WEBSITE FOR SAME ISSUE, TOYOTA IS REFUSING RESPONSIBILITY. *TR

THE DRIVER'S SIDE SUN VISOR FLOPS DOWN, BLOCKING THE DRIVER'S VISION. IT WILL NOT STAY IN THE "UP" POSITION. WHEN IT FALLS DOWN, THIS IS A POTENTIAL SAFETY HAZARD THAT NEEDS TO BE CORRECTED TO PREVENT SERIOUS INJURIES OR DEATHS. *TR

LIKE THOUSANDS OF OTHER 2003 TOYOTA HIGHLANDERS ONLY THE RIGHT SIDE BRAKE LIGHT WILL ILLUMINATE WHEN THE BRAKE PEDAL IS PRESSED. *TR

THE REAR LEFT BRAKE LIGHT DOES NOT WORK DESPITE HAVING REPLACED THE BULB AND FUSE. *TR

THE REAR RIGHT BRAKE LIGHT STOPPED BRIGHTENING UPON HITTING THE BRAKES AT FIRST. THEN A FEW MONTHS LATER, NEITHER BRAKE LIGHT IS LIGHTING UP AT ALL. I ALSO WITNESSED THE SAME ISSUE OCCUR ON ANOTHER 2003 TOYOTA HIGHLANDER WHILE STOPPED IN TRAFFIC. *TR

WE HAVE HAD UNRELIABLE OPERATION OF THE DRIVER-SIDE BRAKE LIGHT FOR SOME TIME (APPROXIMATE INCIDENT DATE ABOVE WAS FOR MOST RECENT INCIDENT). WEB SEARCH TURNS UP NUMEROUS COMPLAINTS WITH SAME SYMPTOMS - ONE EXAMPLE IS AT WWW.TOPIX.COM. SEVERAL REPORTING THIS PROBLEM REPLACED MAJOR COMPONENTS OF TAILLIGHT ASSEMBLY ONLY TO HAVE PROBLEM RECUR. A CALL TO TOYOTA ASKING ABOUT TSB OR RECALL YIELDS NOTHING. *TR

TL* THE CONTACT OWNS A 2003 TOYOTA HIGHLANDER. THE CONTACT STATED THAT THE ENGINE RELEASED A PINK FLUID AS A GURGLING NOISE EMITTED FROM THE STEERING WHEEL COLUMN. THE VEHICLE WAS TOWED TO A LOCAL MECHANIC FOR INSPECTION, WHO FOUND THAT THE ENGINE CYLINDER, BOLT HEAD AND THE THREAD WERE STRIPPED FROM THE CYLINDER BLOCK DUE TO DEFECTIVE MATERIAL. THE VEHICLE WAS REPAIRED. THE FAILURE MILEAGE WAS 99,900 AND THE CURRENT MILEAGE WAS 111,500. UPDATED 6/17/14*CN THE ENGINE BLOCK AND VALVE WERE REPLACED. UPDATED 07/03/14

GRANDMOTHER WAS LEAVING AND DROVE THROUGH A CLOSED WROUGHT IRON GATE THAT WAS OVER 10' TALL AND 16' WIDE. CONTINUED ACCELERATING THROUGH A PARKING LOT ACROSS THE STREET, DROVE OVER A LARGE DECORATIVE BOULDERS AND CAME TO HALT AFTER CRASHING INTO A NEIGHBORS FENCE. SHE SAID THAT SHE ATTEMPTED TO STOP IN FRONT OF HER GATE TO OPEN IT BUT THE BREAKS WOULD NOT WORK AND THE CAR KEPT ACCELERATING. THANKFULLY IT ENDED HOW IT DID LEAVING HER WITH MINOR INJURIES. IT IS ALSO DISGUSTING KNOWING THAT IT COULD HAVE BEEN MUCH WORSE AND IF A CAR DEFECT IS THE REASON NOTHING WILL BE DONE UNTIL DEATHS BEGIN TO OCCUR. *TR

MY 4 CYLINDER ENGINE OVERHEATED VERY QUICK, VERY HIGH, CAUSING A GASKET TO BLOW. UPON REPAIRING THE CATALYTIC CONVERTER AND GASKET, THE MECHANIC RAN INTO ANOTHER ISSUE THAT I'VE BEEN READING ABOUT HAPPENING TO OTHERS, THE THREADS ARE STRIPPED WHERE THEY HOLD THE ENGINE BLOCK. SOMETHING NEEDS TO BE DONE. THERE ARE TOO MANY PEOPLE WRITING ABOUT HAVING THIS ISSUE FOR IT BE A RARE OCCURRENCE FOR THIS TYPE OF VEHICLE. THE COSTS ARE HIGH TO FIX AND TOYOTA NEEDS TO HELP RECTIFY THE PROBLEM. *TR
