I OWN A 2009 HIGHLANDER HYBRID AND AM CONCERNED THAT I AM EXPERIENCING THE SAME TYPE OF PROBLEMS WITH BRAKING THAT ARE NOW BEING REPORTED FOR THE PRIUS. SOMETIMES, WHEN BRAKING IT FEELS LIKE THE BRAKES ARE NOT ENGAGING AND THERE IS A SENSATION THAT THE CAR IS SPEEDING UP. CONTINUED PRESSURE ON THE BRAKE PEDAL FINALLY SLOWS THE CAR DOWN. I WAS RECENTLY INVOLVED IN A MINOR ACCIDENT WHEN I WAS UNABLE TO BRAKE QUICKLY ENOUGH WHEN APPROACHING A TRAFFIC LIGHT AND HIT THE CAR IN FRONT. THE SENSATION THAT THE BRAKES WERE NOT ENGAGING WAS EXPERIENCED AT THAT TIME AS WELL AS ON OTHER OCCASIONS. I REPORTED THIS ISSUE TO MY TOYOTA DEALER JUST A FEW WEEKS AGO, AND THE MECHANIC WHO TEST DROVE THE VEHICLE, WITH ME IN THE PASSENGER SEAT, STATED HE EXPERIENCED A SIMILAR DELAY IN BRAKING. THE BRAKES WERE THEN TESTED USING COMPUTERIZED DIAGNOSTICS AND I WAS TOLD EVERYTHING CHECKED OUT OK BUT WAS OFFERED NO EXPLANATION OF WHY I WAS HAVING THIS ISSUE WITH THE BRAKES. I AM SHARING THIS ISSUE WITH YOU AS I BELIEVE MY HIGHLANDER HYBRID 2009 MAY NOT BE CONSISTENTLY TRUSTWORTHY WHEN THE BRAKES ARE NEEDED. PLEASE ADVISE. *TW

I OWN A 2009 TOYOTA HIGHLANDER HYBRID. IT HAS HAD THREE INSTANCES OF UNINTENDED LOW SPEED ACCELERATION SINCE I PURCHASED IT IN JUNE 2009. THE FIRST TIME IT HAPPENED, IT WAS SO UNEXPECTED AND UNCONVENTIONAL THAT I THOUGHT IT MUST HAVE BEEN A MISTAKE IN MY PERCEPTION. THE SECOND TIME IT HAPPENED I WAS MORE AWARE BECAUSE IT HAD HAPPENED ONCE BEFORE. AND THE THIRD TIME EVEN MORE SO. NOW I AM ALERT FOR THE EVENT AND WILL TRY TO RECORD IT AS ACCURATELY AS POSSIBLE IF IT HAPPENS AGAIN. AS BEST I CAN DESCRIBE IT, I WAS SLOWING DOWN, ALMOST TO A STOP. IT IS AT THE POINT WHERE YOU HAVE SLOWED THE CAR BY BRAKING, THEN TAKE YOUR OFF THE BRAKE OR LIGHTEN THE BRAKING PRIOR TO THE FINAL BRAKING WHICH BRINGS YOU TO A FULL STOP WITHOUT A SMALL JOLT. I PROBABLY WAS TRAVELING BETWEEN 5 AND 10 MILES PER HOUR. I HAD MY FOOT OFF THE GAS AND BELIEVE PROBABLY OFF THE BRAKE AS WELL. ALL OF A SUDDEN THE CAR ACCELERATED. I DEPRESSED THE BRAKE AND THE CAR STOPPED NORMALLY. I HAVE NOT WORKED ON CARS IN YEARS, BUT DID EXTENSIVELY WHEN I WAS A TEENAGER. SO I THINK OF MY SENSES AS REASONABLY ATTENTIVE TO THE SOUNDS AND MOTIONS OF VEHICLES WHICH INDICATE THAT SOMETHING IS AMISS. HOPE THIS HELPS. *TR
BRAKES FADE FOR A BRIEF MOMENT -- PERHAPS HALF OF A SECOND -- AND THEN COME BACK. ALTHOUGH THE BRAKES ARE BEING APPLIED CONSISTENTLY THROUGHOUT, THE SENSATION IS AS IF THE DRIVER WERE EASING OFF THE BRAKE AND THEN COMING BACK ON WITH MORE PRESSURE. *TR

EA18006 · Steering Column Separation
Opened Nov 16, 2018 · Closed Apr 2, 2024
Status: closed (inferred from source dates) · Steering; Steering:column
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.
