NHTSA Safety Investigations, ACURA MDX

Investigations opened by NHTSA into potential safety defects. These are separate from recalls and may or may not result in a recall.

DP, Closed , Model Year: 2022

All wheel drive allegation

The Office of Defects Investigation (ODI) has completed its review of a Petition dated January 9, 2026, requesting an investigation into the loss of the optional all-wheel drive capability in model year (MY) 2021-2023 Acura TLX and MY 2022-2023 Acura MDX vehicles. The Petition alleges failures in th... e interfacing splines between the front wheel drive transaxle and the rear wheel drive power take off unit. Failure of these splines prevents the transfer of drive power to the rear axle, making the vehicle front wheel drive only. The Petition further alleges that this failure reduces vehicle directional control. Most traditional AWD systems utilize mechanical and passive measures. These systems have the tendency to distribute torque along the path of least resistance, such as a wheel that has lost contact with the ground or is on a low friction surface such as ice. To compensate for this, many manufacturers use the brake system to redirect torque to the wheels with more traction. However, in this style of AWD system, a failed drive shaft or similar disconnection prior to the brakes often results in drive power being lost to the disconnected component. The consequence of this loss is the inability to maintain speed with surrounding traffic which increases the risks of collisions and injuries to the vehicle occupants. The Subject Vehicles are built upon a platform that was designed primarily as Front Wheel Drive (FWD). The SH-AWD system functions more as a performance enhancement feature rather than a stability feature. Even if the SH-AWD is nonoperational, the vehicles retain full mobility via FWD. In addition, the Vehicle Stability Assist (VSA) remains functional, ensuring directional stability through traditional engine and brake-based traction control. Although the condition raised by the Petitioner may degrade the vehicle’s performance characteristics, there is insufficient information to indicate a potential unreasonable safety risk. ODI reviewed 62 Vehicle Owner Questionnaires (VOQs) and several EWR Field Reports alleging the loss of SH-AWD and its impact on the driving dynamics of the subject vehicles. During its analysis, ODI determined that the failure is localized to the mechanical interface between the FWD transaxle and the PTU. Specifically, the failure is the shearing or stripping of the interfacing splined shafts between the FWD transaxle and the PTU, resulting in a permanent loss of torque transfer to the rear of the vehicle. Upon reviewing the technical details of SH-AWD, ODI has found that this failure does not result in any loss of motive power or lead to a loss of vehicle control. Several complaints indicated that the operators were unaware of the mechanical fault until encountering a low friction surface or the condition was identified by a technician during routine maintenance. The SH-AWD system lacks any form of direct feedback for monitoring real time torque transfer to the rear wheels. Therefore, the system will continue to display information indicating power is being supplied to the rear wheels even when power is actually only supplied to the front wheels. ODI’s review did not identify sufficient evidence to indicate that the misinformation has presented a safety issue in the field. ODI did not identify any reports of loss of motive power or vehicle control that could be attributed to the loss of SH-AWD. ODI is not aware of any crashes involving the Subject Vehicles that resulted from the loss of SH-AWD. After thoroughly assessing the material submitted by the Petitioner, consumer complaint information in NHTSA’s databases, and other relevant information already in possession of the Agency, NHTSA has not found sufficient evidence to indicate that the loss of AWD as alleged by the Petitioner is likely to present a safety related defect that would warrant a formal investigation. After full consideration of the available information, and in view of NHTSA’s enforcement priorities, the Petition is denied. A denial report will be posted in the Federal Register. The closing of the petition does not constitute a finding by NHTSA that a safety related defect does not exist, and the agency reserves the right to take additional action if warranted by future circumstances. The Petition can be viewed at NHTSA.gov under ODI Number 11712885.Read more

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
