I ALMOST GOT IN TO AN ACCIDENT ON 5/11/2018 DUE TO THE ABS SYSTEM NOT STOPPING THE VEHICLE WHILE DRIVING IN I-95. I GOT A WARNING LIGHT ON THE DASH AS I WAS PRESSING THE BRAKES, LATER THE CAR DID NOT WANTED TO STOP, BUT IT DID NOT PREVENT ME FROM HITTING THE OTHER CAR. I PRESS ON THE EMERGENCY BRAKE AND I WAS ABLE TO STOP THE CAR. LATER, I TOOK THE CAR TO GET DIAGNOSE AND PUT ERROR CODES C1391, ABS ACCUMULATOR LEAK OR MALFUNCTION. CONTACTED DELRAY TOYOTA IN DELRAY BEACH, FL AND THEY DENY TO DO A RECALL WHEN THERE IS AN EXTENTED WARRANTY RECALL ON CAMRY AND PRIUS MODEL LINE FOR THE SAME PROBLEM. CALLED TOYOTA CORP. AND THEY ARE DENYING TO DO ANYTHING TO FIX THE SAFETY PROBLEM WITH THIS VEHICLE. THEY STATED THAT SINCE THERE WERE NOT ENOUGH BUYERS FOR THIS MODEL, THEY WILL NOT COVER OR MAKE A RECALL ON SAFETY FOR THE PUBLIC. I HAVE FOUND OVER ALL THE INTERNET COMPLAINTS ABOUT THE SAME ISSUE. I AM LOOKING FOR A RESOLUTION. A PICTURE OF THE ERRORS CODES ON THE VEHICLE IS INCLUDED ON THE COMPLAINT.

WAS TOLD VEHICLE WAS UNSAFE TO DRIVE WITHOUT REPAIR, INTERNAL PRESSURE LOSS COULD PREVENT CAR FROM STOPPING IN A PANIC SITUATION. ALTHOUGH IT APPEARS THIS IS COVERED BY WARRANTY EXTENSION FOR SOME MODEL YEARS OF HIGHLANDER, CAMRY AND PRIUS, TOYOTA WOULD NOT EXTEND SAME COURTESY TO ME, NOR WAS DEALER ABLE TO OFFER ME A GOODWILL ADJUSTMENT. PUMP ASSEMBLY AND ACTUATOR ASSEMBLY PARTS AND REPAIR COST ABOUT $5300.00.

MY TOYOTA HIGHLANDER HYBRID HAS EXTREMELY POOR BRAKING IN SNOW / ICY CONDITIONS. EVEN AT EXTREMELY LOW SPEEDS (10 TO 15 MPH), THE CAR SKIDS FOR TENS OF FEET BEFORE COMING TO A HALT. THREE TIMES SO FAR, IT CAUSED DANGEROUS SITUATIONS BECAUSE THE CAR KEPT GOING DESPITE FULL ENGAGEMENT OF THE BRAKES. ONCE, I NARROWLY MISSED BEING HIT BY A 53' TRUCK BECAUSE MY CAR ROLLED INTO A MAJOR STREET, JUST BARELY GETTING BY BEFORE THE TRUCK CAME THROUGH. I HAVE ATTEMPTED TO TALK WITH THE DEALER - THE RESPONSE IS THAT HYBRID CARS BRAKE DIFFERENTLY. I HAVE DRIVEN CARS FOR OVER 30 YEARS, AND I KNOW THERE IS A DEFECT IN HOW THE CAR'S HYBRID SYSTEM IS ENGAGING THE BRAKING FUNCTIONALITY. ITS A SHAME THAT A CAR THAT COST 50K ON THE ROAD HAS SUCH A SERIOUS PROBLEM THAT THE MANUFACTURER AND ITS DEALERS REFUSE TO ACKNOWLEDGE. *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.

PE18005 · Upper Steering Column Separation
Opened May 4, 2018 · Closed Nov 20, 2018
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.
