Acura and Honda engineering analysis EA13002
Vehicle Stability Assist Malfunction. NHTSA’s Office of Defects Investigation opened this engineering analysis about the electronic stability control on 4 model years (2005–2006). Opened Feb 21, 2013, closed Mar 29, 2013 after 36 days. It led to safety recall 13V092000. became a recall
What NHTSA says
Source: Office of Defects Investigation, as filedOn 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 havebeen 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 the owner. ODI identified 106 incidents of inappropriate brake activation by the VSA system that appear to be related to the defect conditions addressed by Honda's recall. While many of the incidents reported experiencing significant unexpected braking while driving, none resulted in crashes or injuries. ODI reviewed a VOQ reporting a crash resulting in two fatalities that allegedly may have been related to the VSA conditions investigated in PE12-028 and EA13-002 (VOQ 10492170).After interviewing thecomplainant and reviewing evidence regarding the crash (e.g., police report and witness statements), ODI did not find sufficient evidence to determine that the crash was related to the VSA system. Regarding the 25 incidents of brake activations of short duration due to a yaw rate sensor malfunction, complainants indicate that typically the events are very brief and that the puling effect is mild. This investigation is closed.
A Engineering Analysis is the deeper stage, usually upgraded from a Preliminary Evaluation: NHTSA tests, requests engineering documents and decides whether a safety defect exists. The summary is the agency’s own text from its investigation file, unedited; the opening and closing resumes with the full reasoning are on NHTSA’s site under this number.
What this means for an owner
Source: and what happens nextAn investigation is not a finding that a defect exists, and it puts no duty on anyone. NHTSA opens a Preliminary Evaluation when complaints and other reports suggest a condition worth asking the manufacturer about; it upgrades to an Engineering Analysis when the answers warrant testing; it closes either when it recommends a recall, when the manufacturer recalls on its own, or when no defect trend is found. The agency’s own goals are about four months for a petition, eight for a Preliminary Evaluation or a Recall Query and eighteen for an Engineering Analysis; many run longer.
This one became a recall. The campaign page carries the manufacturer’s filed defect, risk and remedy, the build window and every model year covered; whether one specific vehicle is included is settled by VIN at nhtsa.gov/recalls.

Common questions
Source: NHTSA Office of Defects InvestigationIs EA13002 a recall?
No — it is the investigation that led to one. Recall 13V092000 is the campaign; its page carries the remedy.
Is EA13002 still open?
No. It closed on Mar 29, 2013 and led to recall 13V092000.
Which vehicles does EA13002 cover?
NHTSA opened it on 4 model years: 2005 Acura MDX, 2006 Acura MDX, 2005 Acura RL, 2005 Honda Pilot. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
