NHTSA investigation PE10008 is a Preliminary Evaluation opened on 2010-02-18 and currently closed. The subject of record is TOYOTA COROLLA, which places this file inside the Office of Defects Investigation queue for TOYOTA. Latest activity on this investigation was logged on 2011-05-05 — NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.

A Preliminary Evaluation like PE10008 is the entry point of the federal defect-investigation process. NHTSA engineers scan complaint databases, field reports, and manufacturer data to decide whether an Engineering Analysis is warranted, whether a voluntary recall is already sufficient, or whether the pattern does not rise to a defect finding.

Investigators summarized the matter as follows: "On February 18, 2010, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE10-008 to investigate complaints of steering wander or drift in model year (MY) 2009 and 2010 Toyota Corolla and Matrix vehi..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related TOYOTA files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.

Investigation Summary

On February 18, 2010, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE10-008 to investigate complaints of steering wander or drift in model year (MY) 2009 and 2010 Toyota Corolla and Matrix vehicles. The complaint descriptions indicated dissatisfaction with the on-center steering feel in the subject vehicles. Some drivers (~25%) related the feel to driving in a strong crosswind and others indicated that the effort and attention required to maintain heading increased driver fatigue on long trips. These complaints all relate to the system operating as designed and do not involve failure of any steering system components. The subject vehicles are equipped with an electronic power steering system that was introduced in the MY 2009 vehicles. The power assist, including on-center steering feel, is controlled electronically and is part of the system calibration. Toyota responded to steering feel concerns from some customers by issuing a technical service bulletin (TSB-0140-10 "STEERING ON-CENTER FEEL") that released an optional EPS electronic control unit that has a re-calibrated on-center feel. Accordingly, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency will continue to monitor complaints and other information relating to the alleged defect in the subject vehicles and take further action in the future if warranted by the circumstances. For further details see the attached VRTC and ODI Closing Reports.

About This Investigation Type

A Preliminary Evaluation (PE) is the first phase of NHTSA's investigation process. It is opened when the agency identifies a potential safety defect pattern, usually triggered by consumer complaints, manufacturer reports, or field monitoring. During a PE, NHTSA gathers information to determine whether a formal engineering analysis is warranted.
