FRAME CORROSION
NHTSA Preliminary Evaluation PE09049 — closed, opened 2009-10-06 and involving the TOYOTA TOYOTA.
NHTSA investigation PE09049 is a Preliminary Evaluation opened on 2009-10-06 and currently closed. The subject of record is TOYOTA TOYOTA, which places this file inside the Office of Defects Investigation queue for TOYOTA. Latest activity on this investigation was logged on 2010-01-26 — 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 PE09049 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: "THIS INVESTIGATION WAS OPENED BASED ON 20 REPORTS OF MODEL YEAR (MY) 2000 AND 2001 VEHICLES EXPERIENCING SEVERE CORROSION OF THE FRAME, RESULTING IN EITHER UNDER-BODY MOUNTED SPARE TIRE SEPARATION OR REAR BRAKE FAILURE...." 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
THIS INVESTIGATION WAS OPENED BASED ON 20 REPORTS OF MODEL YEAR (MY) 2000 AND 2001 VEHICLES EXPERIENCING SEVERE CORROSION OF THE FRAME, RESULTING IN EITHER UNDER-BODY MOUNTED SPARE TIRE SEPARATION OR REAR BRAKE FAILURE. THE FAILURE REPORT COUNTS SHOWN ABOVE ARE FOR MY 2000 AND 2001 VEHICLES ONLY. BY LETTER OF NOVEMBER 16, 2009 TOYOTA HAS NOTIFIED THE AGENCY THAT IT WILL CONDUCT A SAFETY RECALL (09V-444) OF APPROXIMATELY 110,000 MODEL YEAR (MY) 2000 THROUGH 2003 TUNDRA VEHICLES. THE AFFECTED RECALLED VEHICLES WERE SOLD OR ARE CURRENTLY REGISTERED IN THE DISTRICT OF COLUMBIA AND THE STATES OF CT, DE, IL, IN, KY, MA, MD, ME, MI, MN, NH, NJ, NY, OH, PA, RI, VA, VT, WI, WV. TOYOTA ALLEGES HIGH AMOUNTS OF "ROAD SALTS" ARE USED IN THESE AREAS AND EXCESSIVE CORROSION OF THE REAR CROSS-MEMBER (TO WHICH THE SPARE TIRE IS MOUNTED) CAN OCCUR AND CAUSE THE SPARE TIRE TO SEPARATE FROM THE VEHICLE AND CAN ALSO LEAD TO REAR BRAKE FAILURE. TOYOTA STATED: "TOYOTA HAS TENTATIVELY CONCLUDED THAT THE ROOT CAUSE IS A COMBINATION OF FACTORS, INCLUDING USAGE IN AREAS WHERE ROAD SALT IS APPLIED, INADEQUATE VEHICLE MAINTENANCE (I.E., NOT FOLLOWING THE RECOMMENDATIONS IN THE OWNER'S MANUAL), THE DESIGN OF THE REAR CROSS-MEMBER, AND MANUFACTURING ISSUES." THE DESIGN OF THE REAR CROSS-MEMBER IS SUCH THAT IT IS OPEN ON THE TOP SIDE AND SUSCEPTIBLE TO ACCUMULATION OF DIRT, WATER AND ROAD SALT. MANUFACTURING ISSUES OF THE REAR CROSS-MEMBER RELATED TO THE COATING PROCESS ALSO AFFECT ITS CORROSION RESISTANCE. TOYOTA ALSO STATES THAT OWNERS OF MY 2000 THROUGH 2003 VEHICLES IN STATES NOT COVERED BY THE RECALL WILL BE NOTIFIED ON HOW TO OBTAIN THE SAME INSPECTION AND REPAIR AS THE RECALLED VEHICLES, FREE OF CHARGE. FURTHER TOYOTA STATES: "PLEASE NOTE THAT WHILE TOYOTA HAS NOT DETERMINED A DEFECT EXISTS IN 2004 THROUGH 2006 MY TUNDRA VEHICLES, TOYOTA PLANS ON INITIATING A FIELD ACTION IN THE NEAR FUTURE TO PREVENT FUTURE CORROSION ON THOSE VEHICLES ORIGINALLY SOLD OR CURRENTLY REGISTERED IN THE AFFECTED
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.
