2017 Altima SR door locks unlocking randomly issue. Anyone had this before?

My car is in the shop as we speak. The doors keep unlocking while I'm driving usually while I'm coming to a stop/at a red light or even sitting idle in P. Even when I dropped it off, sitting there with door open and the thing is unlocking 6 times in a row. Yesterday when I got out of my car and tried to lock it with fob it unlocked immediately and would not lock. Sometimes it will go off for like 12 times in a row when I'm driving.

They even unlock while the car is turned off just parked in the driveway!

The only thing I did recently to my car was replace the battery, which was done at the dealership. This issue seemed to start happening after that. Could be unrelated though.

So far they've replaced a keyfob and BCM with no luck now they wanna try drivers door actuator?

I can't find much of anything online for the specific issue. There are no tech bulletins either.

Try replacing the driver's door lock assembly. The problem you're having is caused by a bouncy cylinder switch about 90% of the time. The switch is located in the lock and not on the cylinder, connected by a linkage rod. If you want to verify it, pop the inside panel and disconnect the lock assembly. The power lock on that door will quit working, but if the other doors stop misbehaving then you know the switch is the culprit.
