PE10015 Preliminary Evaluation Closed

NHTSA investigation PE10015 is a Preliminary Evaluation opened on 2010-05-12 and currently closed. The subject is tracked inside the Office of Defects Investigation queue. Latest activity on this investigation was logged on 2010-09-10 - 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 PE10015 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: "In its June 30, 2010 response to ODI's Information Request letter, General Motors (GM) identified the leak source as cracks in either the fuel tank cross-over tube quick connector (connector) and/or the "hot-plate" weld..." 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.

Investigation Summary

In its June 30, 2010 response to ODI's Information Request letter, General Motors (GM) identified the leak source as cracks in either the fuel tank cross-over tube quick connector (connector) and/or the "hot-plate" weld joint of the connector to the tank. The root causes are attributed to errors in connector material processing, variations in the welding process, and high stresses placed on the driver's side connector during vehicle use. GM also identified the scope of the subject vehicles involved to be those produced from approximately October 22, 2003 through March 19, 2004. GM does not believe the cracks represent an unreasonable risk to motor vehicle safety based on factors that include; low rate of fuel leaking to the ground, detectable fuel odor, the cracks are at the top of the tank, leaks are detectable during refueling, small quantities of fuel that leaks out, and no associated property damage or personal injury claims. On August 13, 2010, GM issued a "Special Coverage Adjustment" to remedy fuel tank quick connector leaks and extend the warranty for this issue to 10 years or 100,000 miles in certain 2004 Chevrolet Corvette and Cadillac XLR vehicles. Vehicle owners will be notified by mail of the adjustment and will also be entitled to reimbursement for previously paid repairs covered under the adjustment. (See file for, SERVICE BULLETIN 10150: SPECIAL COVERAGE ADJUSTMENT-FUEL TANK QUICK CONNECTOR LEAK). The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take further action if warranted by the circumstances.

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.
