2011 TOYOTA HIGHLANDER Unknown Or Other Problems

1. The 3.5L V6 Engine (2GR-FE) failed due to the subsequent loss of lubrication caused by the rupture of the Oil Cooler Pipe (Rubber component), a manufacturing defect known under TSB T-SB-0201-11 (ZE2 Program). The failed engine is currently available for inspection by request at the independent service center before it is disposed of. 2. The defect causes a sudden and severe loss of engine oil. This creates a high probability of the engine seizing (losing all power) while driving at highway speeds, resulting in a complete loss of propulsion and placing occupants at severe risk of collision. 3. The failure was confirmed, not reproduced. The vehicle was initially diagnosed with misfire codes (P0300, P0301). New spark plugs and ignition coils were installed in an attempt to resolve the issue. As the misfire persisted, the mechanic performed a compression test, confirming catastrophic zero compression failure in cylinders 1 and 2. Professional diagnostics then revealed critical codes: P1603 (ECM Malfunction), P1604 (Startability Malfunction), and P1605 (Rough Idling). These codes confirm a severe internal engine issue, consistent with permanent damage sustained during the oil loss event caused by the ZE2 pipe defect in July 2024. 4. No, not physically inspected by the manufacturer. The manufacturer (Toyota Executive Office Case Manager) was provided with certified documentation of the failure, including the photo of the faulty pipe, maintenance records during our ownership, and the dealership purchase statement for the replacement part. Toyota refused to authorize a physical diagnostic inspection of the failed engine at a dealership before denying goodwill assistance. 5.Yes. The initial lubrication loss event on July 4, 2024, was preceded by a message displayed on the dashboard (followed by a second failure event in October 2025 indicated by a flashing Check Engine light and the Traction Control light).

THERE IS A KNOWN DEFECT IN TOYOTA HIGHLANDERS (2010 - 2013) SUN VISORS. THE VISOR NO LONGER STAYS IN EITHER THE UPRIGHT OR DOWNWARD POSITION. IT IS EITHER AT A 45 DEGREE ANGLE WHEN PLACED IN THE "UP" POSITION OR IS IN A POSITION TO SLIGHTLY OBSCURE VISIBILITY IN THE "DOWN" POSITION. TOYOTA OFFERED A WARRANTY ENHANCEMENT (LETTER ZF1) HOWEVER I AM NOW PAST THE EXTENDED WARRANTY PERIOD. THIS IS A HAZARD IN DRIVING AND WOULD BE HAZARDOUS TO THE DRIVER SHOULD THERE BE AN ACCIDENT - THE VISOR WOULD HIT THE DRIVER IN THE FOREHEAD OR FACE SHOULD THERE BE AN IMPACT.

Mileage: 130,000

SUN VISORS WILL NOT STAY IN UPRIGHT POSITION.

ALARM SYSTEM GOES OFF RANDOMLY HOOD LATCH SWITCH TO BE THE PROBLEM.. TOYOTA IS CHARGING 300 PLUS $ FOR MANUFACTURING DEFECT - CHECK TECHINICAL BULLETEN ( T-SB-0200-10 )I FEEL ITS NOT FAIR I HAVE

THE CAR IS SITTING STILL WITH THE ENGINE OFF. THE HORN HAS GONE OFF SEVERAL TIMES. THIS HAS HAPPENED IN OUR DRIVEWAY AND IN THE GARAGE WITH NO ONE AROUND.

WHEN CAR GOES ABOVE AROUND 35-45 MPH A ABNORMAL WHINE NOISE EMANATES FROM THE TRANSMISSION

BOTH DRIVER AND PASSENGER FRONT SIDE DOORS WILL NOT UNLOCK IN 2013 ONE WAS REPLACED AT THE DEALERSHIP AND THE VEHICLE HAD TO BE BROUGHT IN 3 TIMES TO GET IT RIGHT. THAT WITH ONLY OWNING IT AFTER 2 YEARS WAS RIDICULOUS. THE ACTUAL LOCK ACTUATOR COSTS APPROX $250 A PIECE TO REPLACE AND WE KNOW IT IS NOT THE FUSE IT WAS CHECKED. FIXED IN 2013 UNDER WARRANTY BUT A MONTH AFTER BEING PAID OFF IN 2016 THEY BOTH STOPPED WORKING. I REFUSE TO SPEND $500 ON PARTS AND WHO KNOWS HOW MUCH MORE FOR LABOR. I WILL NEVER BUY A TOYOTA AGAIN THIS SHOULD DEFINITELY BE A RECALL AS NUMEROUS CUSTOMERS ON INTERNET COMPLAIN ABOUT THE SAME EXACT PROBLEMS. SHOULD BE RECALLED LIKE THE SUN VISORS WERE

MY DRIVER SIDE VISOR LOST ALL TENSION. I HAD TO EITHER HOLD IT UP OR TIE IT OUT OF THE WAY. I HAD IT REPLACED AT LOWE TOYOTA IN WARNER ROBINS, GA FOR $199.87. I WOULD NOT EXPECT A VISOR TO TEAR UP EVEN FOR A 2011 MODEL. IT WAS A SAFETY ISSUE THAT NEEDED TO BE FIXED. I THINK THERE SHOULD BE A RECALL ON THESE VISORS AND REIMBURSEMENT FOR REPLACING THEM.

HEATER/AC ASSEMBLY IS LEAKING ONTO A CONTROL MODULE UNDER THE DASH WHICH I BELIEVE THE THE AIRBAG MODULE AND SOAKING THE FRONT DRIVERS AND PASSENGERS CARPETS AND PADDING. CHECKED FOR BLOCKAGE IN DRAIN TUBE. NONE, USED COMPRESSED AIR TO BLOW OUT DRAIN TUBE JUST IN CASE. DID NOT SOLVE ISSUE. REMOVED PASSENGERS SIDE PANEL AND FOUND THAT THE FACTORY SEAM OF THE AC/HEATER ASSEMBLY WAS LEAKING WATER WHEN THE AC IS ON. (I HAVE VIDEO) THE DESIGN OF THE ASSEMBLY IS POOR IN THAT THE SEAM SPLITS THE ASSEMBLY LEFT AND RIGHT RATHER THAN TOP AND BOTTOM. REPAIR OF THE UNIT WOULD HAVE REQUIRED COMPLETE REMOVAL OF DASH, STEERING, ETC. TO SOLVE THIS, I PLACED 3M GLASS SETTING BUTYL TAPE OVER THE SEAM SUCH THAT THE SEAM IN THE UNIT WAS SEALED ABOVE THE CONDENSATION DRAIN. THIS RESOLVED THE ISSUE.

ON JULY 19 MY DAUGHTER HIT THE BUTTON TO CLOSE THE REAR LIFT GATE. THE HANDLE BROKE AWAY FROM THE CAR. IT LOOKED LIKE THE SCREW WAS STRIPPED. TOOK IT TO THE DEALER AUG 5. THEY SAID IT IS A FULL REAR DOOR REPLACEMENT WITH ESTIMATED COST OF $3000 - $5000. THEY WERE VERY FAMILIAR WITH THE PROBLEM. AFTER RESEARCHING ONLINE I FOUND THIS IS A COMMON PROBLEM WITH 2008-2012 HIGHLANDERS AND TOYOTA HAS BEEN AWARE. THERE IS A CLASS ACTION LAWSUIT REGARDING IT ALSO. CALLED TOYOTA AND THEY SAID I AM OUT OF WARRANTY AND OUT OF LUCK.

THE SUN VISOR IN THE DRIVER SIDE IS STUCK IN HALF WAY DOWN POSITION, HIT MY FOREHEAD TWICE ALREADY ON THIS.

THE SUN VISOR POPPED WHEN I WAS PULLING IT DOWN TO SHEILD MY EYES AND NOW IT WILL NOT RETURN TO ORIGINAL POSITION. CONCERN AS IT GETS IN MY WAY WHEN DRIVING. THIS IS THE DRIVERS SIDE VISOR WHICH I TEND TO HIT MY HEAD ON AND HAVE TO MOVE MY SEAT LOWER IN ORDER TO SEE PROPERLY. I TOOK IT TO MY DEALERSHIP AND THEY TOLD ME IT WOULD BE $300 TO FIX. THAT IS RIDICULOUS AS I FEEL THIS IS A FAULTY PART THAT COULD BE A HAZARDOUS SITUATION IF NOT TAKEN CARE OF. RECAL MAY BE IN ORDER TO CORRECT THIS ISSUE.

THE SPRING IN THE DRIVER'S SIDE SUN VISOR BROKE AND IT NOW HANGS DOWN. IT WON'T STAY UP OR IN A POSITION TO BLOCK THE SUN. WE HAVE A BUNGY CORD TO HOLD IT OUT OF OUR LINE OF VISION BUT CANNOT USE IT. IT STILL HANGS DOWN A LITTLE AND "POPS OUT" FREQUENTLY BLOCKING VISION. VERY DANGEROUS. NOT UNDER WARRANTY I AM TOLD. *TR
