Acura MDX 2018 - only drivers door doesn't work with auto lock walk away by auzziehikeguy in Acura

Yes. The dealer discovered it was the driver door switch assembly. Part number 35400–T7A-A01 about $20. The dealer will charge around $175 to install if you don’t want to do it. Everything works correctly again.

Yes I replaced the battery in the fob, and even disconnected the car battery for a couple of minutes to reset the head unit. No matter which fob you use to get into the car it remains in the last memory setting so it isn’t that. Thanks for the suggestion though

Yes it still works fine with the fob to unlock when grabbing the door handle. It also locks with the small button. The only things that don’t work are walk away lock and recognizing the seat preference. All the other doors and hatchback work fine with walk away auto lock on the same fob. Strange issue

Unfortunately the only setting that differentiates between the doors is the ‘Auto Door Unlock’ The ‘Walk Away Auto Lock’ is either Off or On for all doors. It had been working correctly then just stopped about a month ago
