Inadvertent Air Bag Deployment

The investigation was opened based on reports of frontal air bag inadvertent deployments (ABIDs) on model year (MY) 2003-2004 Honda Odyssey vehicles.In its response dated September 20, 2013, Honda indicated that the MY 2003 Acura MDX vehicles use a SRS Electronic Control Unit (ECU) which contains th... e same electrical component (an ASIC chip) as the Odyssey, and has a similar vehicle electrical system architecture.Through inspection and analysis of field returned vehicles and components, Honda determined that the SRS ECUs used in the Odyssey and MDX can degrade over time and result in the deployment of either the driver and/or the passenger frontal air bags.The deployment occurs without a crash or impact, and may occur while the vehicle is being operated on the roadway.Honda?s analysis determined that, when actuated, the electric power door lock circuitry on both the Odyssey and MDX produces high levels of electrical noise.The electrical noise, which is transmitted to the SRS ECU via harnessing, may cause damage to the ASIC chip.Cumulative damage to the ASIC chip results in an inadvertent deployment event.A similar defect issue was investigated under Engineering Analysis (EA) 12-001, which led to recalls 12V-527 and 13V-040, and to recall 13V-029.In total, ODI is aware of 25 frontal ABIDs on the Odyssey vehicle and another three ABIDs on the MDX vehicles (data as of August 01, 2013).Consistent with findings in EA12-001, the failure data indicated an increasing incident trend with several of the incidents occurring in recent years.The incidents resulted in 9 alleged injuries consisting of burns, cuts and bruises to the upper body region; there were no reports of control loss or vehicle crashes.Some owners noted an air bag warning light and/or chime activated just seconds prior to the air bag deployment while others stated that they did not observe either.ODI notes that Honda also reported ABIDs of non-frontal, side torso and curtain air bags in its submissions. These incidents, which were generally associated with door closures and underbody object strikes, are not related to (or caused by) the noise induced failure of the ASIC chip. Accordingly they were not considered relevant to the investigation.In its September 18, 2013 letter to ODI, Honda announced it will recall 318.7k MY2003-2004 Honda Odyssey and an additional 56k MY2003 Acura MDX, totaling 374.7k vehicles.Under recall 13V-412, Honda will install an electrical noise suppressor unit (a filter) between the ECU and the vehicle electrical harness on each affected vehicle.The remedy filter blocks harmful electrical noise from entering the SRS ECU and is a similar approach as that used in other recall actions.In its supplemental response of December 03, 2013, Honda reported that it also reviewed field data from other peer Honda vehicles, including the MY 2003 Honda Accord, MY 2003-2004 Honda FCX, and the MY 2004 Acura TSX, that use the same suspect ASIC chip.While Honda identified evidence of ABID on these (non-recalled) vehicles, the rate of incidence was lower and the failure trend, which was declining or random, differed from that seen on all other recalled vehicles, including those of other manufacturers.Honda documents identified differences in electrical system architecture and electrical noise emission levels between the non-recalled and recalled products.Honda?s analysis concluded these differences would reduce failure occurrence for the suspect ASIC chip in the non-recalled products.ODI?s review of Honda's information, and the analysis it undertook, indicates that the 13V-412 recall action addresses the safety concerns currently prRead more

Vehicle Stability Assist Malfunction

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 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.Read more
