These vehicles may have received a replacement driver frontal air bag module as part of a vehicle repair. Due to a manufacturing issue, the replacement NADI inflator may absorb moisture, causing the inflator to rupture or the air bag cushion to underinflate.

Risk: In the event of a crash necessitating air bag deployment, an inflator rupture may result in metal fragments striking the driver or other occupants. An underinflated air bag cushion may not properly protect the occupant. These scenarios increase the risk of serious injury or death.

ENGINE

One morning I noticed the engine in 2016 Acura MDX was making a loud knocking noise. The check engine light immediately came on. As such, I immediately drove to Acura of Baton Rouge to report the problem to get it fixed. They ran a diagnostic on the car and didn't find anything. For some reason they said they needed to take the oil pan off to see if there was metal in the oil pan. I said ok. I got a call a few days later from the service department stating that I needed a new engine at the price of $8,000 because they said a connecting road bearing had failed which destroyed the 6th cylinder. The vehicle only had 78,000 miles on it. The oil had always been timely changed. There is no reason the connecting rod bearing should fail on an engine with 78,000 miles on it. I contacted Honda and Honda eventually came back to me and said they would not do anything to help replace the engine because the car was not under warranty, despite the Office of Defect having an ongoing investigation into connecting rod bearing failures in 2016 Acura MDX's. Honda has not operated in good faith, this is a major safety issue and the federal government must do something before people are hurt as a result of Honda's negligence.

The hazard warning switch on my 2011 Acura MDX Technology & Entertainment Package VIN [XXX] sticks. It is due to a manufacturing defect and not because of normal wear and tear. That is a safety concern because when it is pressed and sticks, such as when giving the right of way to an emergency vehicle, or in bad weather, it not possible to make it unstuck while driving, and requires a screwdriver to pry it back to unstuck position, and if that option is not available then the stuck hazard switch will drain the battery when the vehicle is shut down. Please refer to enclosed Acura ServiceNews Article B15070C. On 8/9/2025, for my service at Hendrick Acura, I requested this known safety issue be fixed. I demonstrated by pressing the hazard switch that got stuck and required a screwdriver to unstick it. But the dealer unreasonably wanted me to pay $99 diagnostic fee to troubleshoot an obvious issue and even when I showed them the Acura ServiceNews Article B15070C. So, I was forced to confirm the issue indirectly myself. On 8/11/2025, I ordered a replacement hazard switch part number 33510-STX-A02 from another Acura dealer Contemporary Cars, for $37.02, per enclosed, even though it was a waste of my money. I swapped out the hazard switch and as expected it still got stuck. I have enclosed two pictures of my DIY diagnostic. I then searched for replacement dashboard center panel online from the Acura dealers, but I am unable to find any available. I then contacted Acura Client Relations on 8/25/2025, and they opened a Case # [XXX]. Kevin from Acura Client Relations called and stated that B15070C does not apply to my VIN. But I disagree because B15070C states for 'Affected Vehicles' - "2010-13 MDX (All trim levels except base." Hence, I am contacting NHTSA to ask Acura to cover my VIN as a saftey recall, and either provide me a replacement center panel that does not have the same manufacturing defect, or ask Hendrick Acura to replace it free of cost. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION A

The idle stop feature does not work correctly. A couple times the car did not restart while stopped at a red light. Had to put into park and took about a minute to restart.

UNKNOWN OR OTHER

The auto start feature on the vehicle has been failing. When you come to a stop the engine’s start feature enables but when proceeding to start moving again the vehicle stalls out and will not restart right away. The vehicle must sit for about 30secs or after two tries in order to restart up. It has stalled out on me while in traffic on the highway, at traffic lights, stop signs. My most recent experience was me being stuck at an intersection unable to move for an ambulance and firetruck in route to an emergency. This issue has put my safety as well as others at risk many times. I have voiced my concerns many times with the dealership but they state there is nothing wrong with my auto start feature nor any other issues that can contribute to this. Any help with this issues is appreciated.
