MY PROBLEM IS WITH THE LOW TIRE WARNING SYSTEM. MY ISSUE IS THAT YOU CANNOT MANUALLY RESET THIS WARNING LIGHT AS WITH OTHER CARS. I HAVE HAD TO TAKE MY CAR TO THE DEALER TWICE IN THE LAST 12 MONTHS FOR THEM TO PROPERLY INFLATE/RESET THE SYSTEM. ALL MY TIRES WERE PROPERLY INFLATED EXCEPT FOR THE SPARE. MYSELF AND FIRESTONE AUTO CARE COULD NOT GET THE WARNING LIGHT TO GO AWAY. FINALLY, AFTER MONTHS OF HAVING THE WARNING LIGHT ON, I WAS ABLE TO TAKE THE CAR TO THE DEALER AND THEY PROPERLY RESET ALL THE TIRES INCLUDING THE SPARE AND THE WARNING LIGHT FINALLY WENT OFF. SEEMS LIKE A PLOY TO GET YOU TO GO TO THE DEALER. THE DEALER INDICATED THAT THEY HAVE HAD A LOT OF THOSE ISSUES DUE TO THE CHANGES IN THE TEMPERATURE. IF ALL THE TIRES ARE PROPERLY INFLATED, THE WARNING LIGHT CAN STILL GO OFF IF BECAUSE YOUR SPARE TIRE MAY BE LOW. THIS IS A SAFETY ISSUE TO ME AS YOU MAY NOT KNOW THAT YOU REALLY HAVE A LOW TIRE THAT COULD AFFECT DRIVING. IF THE LIGHT IS ALREADY ON DUE TO A LOW SPARE TIRE, AND A REGULAR TIRE GOES LOW, ONE WOULD HAVE NO WAY OF KNOWING AS THE LIGHT IS ALREADY ON. *TR

2EA18006 · 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.
