NHTSA investigation PE11034 is a Preliminary Evaluation opened on 2011-09-23 and currently closed. The subject of record is HONDA ODYSSEY, which places this file inside the Office of Defects Investigation queue for HONDA. Latest activity on this investigation was logged on 2012-02-29 — 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 PE11034 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: "The investigation found that the liftgate struts were failing prematurely and at an abnormal rate in certain model year (MY) 2008 Honda Odyssey Touring and 2009 Honda Odyssey Touring and EX-L model vehicles equipped with..." 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 HONDA files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.

Investigation Summary

The investigation found that the liftgate struts were failing prematurely and at an abnormal rate in certain model year (MY) 2008 Honda Odyssey Touring and 2009 Honda Odyssey Touring and EX-L model vehicles equipped with power-operated rear liftgates (note: MY 2008 Odyssey EX-L was not equipped with a power liftgate). Unlike vehicles with non-powered (manual) liftgates, the subject vehicle's liftgate can be opened automatically (via the power liftgate motor) even when the struts are in a degraded condition and can no longer support it in the open position. Consumers standing or accessing the rear cargo area under the liftgate and expecting the liftgate will stay open, can be struck when the liftgate unexpectedly drops, or can be trapped under the liftgate as it power closes, both of which can occur when the system detects and reacts to degraded struts. By contrast, users of a manual liftgate assist in lifting it, and thus notice the lack of support as the struts degrade. Honda is conducting a recall to replace the liftgate struts in approximately 45,747 MY 2008 and early MY 2009 Odyssey vehicles equipped with power liftgates built before a manufacturing change of the liftgate strut assembly that occurred on January 13, 2009 (see NHTSA Safety Recall No. 12V-062 for further details). The vehicles subject to the recall account for 101 complaints, 12 injuries, and 5,630 of the warranty claims shown above (i.e., the MY 2009 and 2010 vehicles built after the manufacturing change experience lower failure rates). In addition, and based on consumer complaints to NHTSA, Odyssey vehicles without power liftgates experience lower complaint and injury rates than the Odyssey vehicles equipped with power liftgates (subject vehicles). The reports cited above can be reviewed online at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification (ODI) numbers: 10442027, 10441232, 10437461, 10432557, 10430420, 10429962, 10412908, 10401388, 10395475, 10390216, 10343678,

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.
