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).

Dear Sir/Madam, I am writing to file a formal complaint regarding persistent safety issues with my 2011 Toyota Highlander V6 AWD. Specifically, I have experienced significant problems related to the engine timing guide, timing chain, transmission system, which pose a risk to both vehicle occupants and other road users. Vehicle Information: Toyota Highlander V6 AWD, VIN: [XXX] Description of the Issue: The transmission in my Highlander has exhibited the following problems: 1) Low engine oil pressure, ticking Noise: There is low engine pressure, faulty guides timing chains, recurring ticking noise. This noise represents issues from the powertrain area and has raised concerns about potential mechanical flaws1. 2) Defective components, slipping Transmission: The transmission surges/slips affecting overall control and safety. This issue has been reported by other Highlander owners as well. Cross-Referencing Other Complaints and Recalls: 3) They did not go far back, Per the NHTSA database, there have been two documented complaints related to transmission issues in the 2011 Toyota Highlander V6 AWD, these complaints align with my experience, however they have not sent me the recall notice. In fact, Toyota has faced recalls and technical service bulletins (TSBs) related to transmission problems in various Highlander models: The 8-speed UA80E/UA80F automatic transmission used in the 2020 Highlander received a TSB for shift flare during wide-open throttle acceleration from 40 – 60 mph and during the upshift from 2nd to 3rd gear. Toyota addressed this issue under warranty1. The 6-speed U660F/U760E automatic transmission, used in earlier Highlander models, was generally reliable. However, the introduction of the 8-speed UA80E/UA80F unit caused initial problems1. Request for Action: Per NHTSA findings please ensure all the models sharing the chassis, model family, part and Toyota transmission oil are included in recall or service campaign. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C.

DRIVING ON A CITY STREET AT ABOUT 35 MILES PER HOUR I WAS HEADING HOME WITH MY KIDS (5 Y.O. AND 7 Y.O.) WHEN THE VEHICLE DECELERATED AND LOST POWER WHILE I WAS DRIVING IN TRAFFIC, I WAS FORTUNATE THAT THE CARE ROLLED LONG ENOUGH TO PULL OVER TO A SAFE SPOT WITH MY CHILDREN AND CALL FOR A TOW. LIGHTS THAT CAME ON CHECK HYBRID SYSTEM, CHECK BRAKE SYSTEM, CHECK 4WD SYSTEM, AND THE CHECK ENGINE LIGHT CAME ON. AFTER THE VEHICLE WAS INSPECTED AT TOYOTA OF CERRITOS I WAS INFORMED THAT THE MASTER MECHANIC HAD TO PLACE A TICKET WITH TOYOTA MOTOR COMPANY TO FIGURE OUT THE ISSUE DUE TO ALL THE CODES THAT WERE LOGGED AFTER THE DIAGNOSTIC. TOYOTA MOTOR INFORMED MECHANIC IT WAS HYBRID INVERTER FAILURE. THIS COULD OF BEEN A HORRIBLE SITUATION HAD I BEEN DRIVING ON THE FREEWAY AND MY CAR SUDDENLY STOPPED FUNCTION LIKE IT DID ON THE EVENING OF 11/05/2019.

MY 2011 TOYOTA HIGHLANDER V6 AWD SUFFERED A SUDDEN OIL COOLER PIPE FAILURE/RUPTURE LEADING TO CATASTROPHIC ENGINE FAILURE/DAMAGE AT APPROXIMATELY 85,000 MILES. THIS IS A KNOWN DEFECT WITH CERTAIN 2008-2011 HIGHLANDERS AND WAS THE SUBJECT OF A SERVICE BULLETIN AND EVENTUALLY A WARRANTY ENHANCEMENT (ZE2) STARTING IN 2014, BUT WE WERE NEVER NOTIFIED OF THIS ISSUE VIA MAIL OR BY THE TOYOTA DEALER AT WHICH THE VEHICLE IS REGULARLY SERVICED. THE VEHICLE WAS TRAVELING ON THE HIGHWAY WHEN THE PROBLEM OCCURRED. THE VEHICLE WAS THEN TOWED TO THE DEALERSHIP WHERE IT WAS FOUND THAT THE SUDDEN LOSS OF OIL HAD CAUSED CATASTROPHIC ENGINE DAMAGE DUE TO A BENT ROD FROM RUNNING WITHOUT OIL. AS THIS PROBLEM CAN LEAD TO MAJOR SAFETY ISSUES DUE TO SUDDEN LOSS OF POWER (NOT TO MENTION THE POTENTIAL FOR SEVERAL THOUSAND DOLLARS IN DAMAGE IF A COMPLETE ENGINE REPLACEMENT IS NEEDED) A MANDATORY RECALL SHOULD BE PERFORMED.

T-SB-0201-11 FROM TOYOTA STATES "SOME VEHICLES EQUIPPED WITH 2GR-FE/FXE TOWING PACKAGE ENGINES MAY EXHIBIT AN OIL SEEP FROM THE ENGINE OIL COOLER PIPES." THIS TSB AFFECTS TOYOTA AND LEXUS VEHICLES GOING BACK TO AT LEAST 2008-PRESENT. THIS IS A MAJOR ISSUE, AND I FEEL THIS SHOULD BE HANDLED AS A RECALL INSTEAD OF A TSB DUE TO THE SEVERITY OF THE ISSUE IF/WHEN THE PIPE BREAKS. I RECENTLY ELECTED TO HAVE MY VEHICLE REPAIRED ON MY OWN JUST SO I WOULDN'T HAVE TO WORRY ABOUT THIS ISSUE HAPPENING TO ME OR MY WIFE, AND THUS BLOWING UP MY HIGHLANDER'S ENGINE CAUSING THOUSANDS OF DOLLARS IN DAMAGES. SEEMS PRETTY BAD THAT A RECALL CAN BE ISSUED FOR FLOOR MATS AND ACCELERATOR ISSUES, BUT NO RECALL IS ISSUED FOR THIS ISSUE WHICH CAN DRAIN THE OIL FROM YOUR ENGINE IN A MINUTE, BLOW UP YOUR ENGINE, AND THEN POSSIBLY WRECK YOUR VEHICLE. CONSUMER'S ENGINES ARE NOW BEING DESTROYED, AND THIS IS SHOWING UP IN DIFFERENT ONLINE FORUMS. I FEEL THAT THE NHTSA NEEDS TO FORCE TOYOTA TO REPLACE ALL OF THE DEFECTIVE ENGINE OIL COOLER PIPES WITH THE NEWER METAL ONES THAT THE TSB ADDRESSES. THEY SHOULD ALSO BE FORCED TO REIMBURSE ALL COSTS TO THOSE INDIVIDUALS THAT EITHER NEEDED TO HAVE THE REPAIR DONE, OR DECIDED TO PREVENTATIVELY HAVE THE REPAIR DONE ON THEIR OWN BEFORE THOSE PIPES BURST ON THEIR OWN. *TR

On November 16, 2018, the Office of Defects Investigation (ODI) opened an Engineering Analysis (EA18-006) as an upgrade to a Preliminary Evaluation (PE18-005). The investigation focused on allegations of steering wheel separation from the lower steering column after using the tilt and/or telescoping mechanism. Given the separation occurring when operating the tilt and/or telescoping function and failure of both shear capsules to maintain the lower steering column mounting position, potential for shear capsule damage in the known failures due to collisions, the overall low rate of occurrence, and the updated manufacturer documentation, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists. The agency reserves right to take further action if warranted by the circumstances. A detailed summary of the investigation is attached to this closing resume. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

Status: closed (inferred from source dates) · Steering; Steering:column
On May 4, 2018, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE18-005 to investigate three allegations of steering column separation for Model Year (MY) 2008 through 2013 Toyota Highlander vehicles. Two (2) of the 3 complaints were received by ODI in April 2018 and occurred while the vehicle was in motion. Since opening PE18-005, one (1) additional VOQ involving steering column separation has been received. This incident occurred while the vehicle was stationary.As part of PE18-005, ODI examined the field data, warranty data, and relevant technical information submitted by Toyota in response to the PE18-005 information request letter. Ten (10) additional incidents of steering column separation were identified. Four (4) of these instances occurred while driving. During PE18-005, ODI confirmed that the steering columns in the subject vehicles are equipped with breakaway capsules that are designed to collapse/shear during certain types of vehicle collisions. This design feature aims to reduce driver injury severity from impact with the steering wheel in frontal vehicle collisions. There is no direct method for detecting when the capsules in the subject vehicles have sheared. If the driver operates the tilt/telescoping feature after the breakaway capsules have separated, the steering column may drop out of position and could subsequently detach entirely from the rest of the steering assembly. Loss of steering while driving may cause a loss of vehicle control, which could lead to a vehicle crash.To date, ODI has identified 14 incidents involving complete steering column separation, 6 of which occurred while driving. One of these incidents involved a minor crash. Additionally, there have been 16 events where the steering column dropped from the dashboard mounting brackets, but column separation did not occur. Four of these incidents happened while driving. Of these 30 total separation/drop incidents, 5 of the vehicles have evidence of minor collision repairs months or years prior to the steering column failure.This investigation has been upgraded an to Engineering Analysis (EA18-006) in order to 1) conduct a more detailed analysis of the conditions that may cause the steering column breakaway capsules to separate and 2) assess factors that may contribute to the problem of failing to detect and repair breakaway capsules after they have separated. Toyota has recently revised their repair manual and issued a Collision Repair Information Bulletin to help address the second concern.The VOQs associated with this investigation can be viewed at www.NHTSA.gov under the following ODI complaint numbers: 11141761, 11083623, 11083280, 10888043.

Of these 30 total separation/drop incidents, 5 of the vehicles have evidence of minor collision repairs months or years prior to the steering column failure.This investigation has been upgraded an to Engineering Analysis (EA18-006) in order to 1) conduct a more detailed analysis of the conditions that may cause the steering column breakaway capsules to separate and 2) assess factors that may contribute to the problem of failing to detect and repair breakaway capsules after they have separated. Toyota has recently revised their repair manual and issued a Collision Repair Information Bulletin to help address the second concern.The VOQs associated with this investigation can be viewed at www.NHTSA.gov under the following ODI complaint numbers: 11141761, 11083623, 11083280, 10888043.
