NHTSA investigation EA13002 is a Engineering Analysis opened on 2013-02-21 and currently closed. The subject of record is HONDA HONDA, which places this file inside the Office of Defects Investigation queue for HONDA. Latest activity on this investigation was logged on 2013-03-29 — NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.

An Engineering Analysis like EA13002 is the deeper technical phase that follows a PE. NHTSA requests design, warranty, and field-failure data from the manufacturer, conducts its own testing when needed, and determines whether the evidence supports a safety defect finding that would compel a recall.

Investigators summarized the matter as follows: "On March 14, 2013, American Honda Motor Co., Inc. (Honda) submitted a Defect Information Report to NHTSA identifying a defect in the Vehicle Stability Assist (VSA) system in approximately 183,576 model year (MY) 2005 Hon..." 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

On March 14, 2013, American Honda Motor Co., Inc. (Honda) submitted a Defect Information Report to NHTSA identifying a defect in the Vehicle Stability Assist (VSA) system in approximately 183,576 model year (MY) 2005 Honda Pilot, Acura RL and MY 2005-2006 Acura MDX vehicles (NHTSA Recall No 13V-092). The population and failure counts provided pertain only to the MY 2005 Honda Pilots that were the subject of this investigation. Honda's recall addresses two conditions in the VSA system that could result in inappropriate brake activation. The first condition is related to a manufacturing concern with a capacitor in the VSA electronic control unit (ECU) circuit board. According to Honda, VSA systems with damaged capacitors may apply a small amount of braking force for a fraction of a second, when the brake pedal is not applied by the driver. If the driver does apply the brake pedal during a malfunction, the VSA system may employ the brake assist feature rapidly increasing braking force independent of the amount of pressure the driver applies to the brake pedal (releasing the brake pedal would end the brake assist activation in such events). The second condition applied to a portion of the MY 2005 Pilot vehicles manufactured at the Alabama assembly plant that may have been assembled without tightening one of the VSA system electrical ground connector fasteners to the proper torque. According to Honda, an improperly torqued fastener can result in increased electrical resistance in the VSA system, causing an incorrect signal to be sent to the VSA ECU, which may result in inappropriate braking while driving with no pedal application by the driver. The owners of all affected vehicles will be contacted by mail and asked to take their vehicle to a Honda or Acura dealer who will install a partial wiring harness containing a capacitor for the VSA modulator and, if necessary, inspect and tighten the affected electrical ground fastener. All work will be performed at no charge to t

About This Investigation Type

An Engineering Analysis (EA) is the in-depth phase following a Preliminary Evaluation. NHTSA engineers conduct testing, collect data from manufacturers, and perform detailed technical analysis to determine whether a safety defect exists. An EA may lead to a voluntary recall by the manufacturer or, in rare cases, a mandatory recall order.
