It is still listed as a maintenance item for all Teslas: Vehicle Maintenance | Tesla SupportIt used to be listed as a maintenance item. I don’t think it is any more.
There’s some reasonable debate as to whether it’s necessary at all.
Air Conditioning Service
Air conditioning service replaces the A/C desiccant bag for better longevity and efficiency of your air conditioning system. We recommend following the following air conditioning service schedule:
**We recommend replacing your A/C desiccant bag every 6 years for Model 3 produced in 2017-2021 if it doesn’t have a heat pump.
Model 3 Replace your A/C desiccant bag every 4 years.** Model Y Replace your A/C desiccant bag every 4 years. Model S
Model XReplace your A/C desiccant bag every 3 years.†
†We recommend replacing your A/C desiccant bag every 2 years for Model S vehicles produced in 2012-2020 and every 4 years for Model X vehicles produced in 2012-2020.
Exactly correct. That any manufacturer that does this is trying to see how gullible their customers are.
Apparently GM also has done this for their own EV products, and it is just as stupid and unneeded.
I have to think that the manufactures know something you don't. I'm pretty sure I saw one site say that the desiccant in the new AC systems breaks down and can clog the system causing catastrophic failure.This would seem to be a new added profit line for the manufacturers, for the last forever, no air conditioned vehicle (or your home AC for that matter) has this as a scheduled replacement. It's just not a thing unless the system is opened / discharged for another repair.
This shows our HEPA filter needing regular replacement. I thought I recently saw a post indicating that is no longer true and was changed to a lifetime filter. Have not checked with my SC yet.It is still listed as a maintenance item for all Teslas: Vehicle Maintenance | Tesla Support
I think GM has it as a maintenance item on the Bolt, and even the Corvette, as well. (Though I seem to recall they put it at 7 years.)

Tesla doesn't seem to list service for things where it isn't necessary. For example, they originally had schedules for changing the gear oil in the drive units, after some collection of data they increased the maintenance interval, and then after even more data they decided that the fluid never needs to be changed and removed it from the maintenance schedule. Same with the battery coolant, they now say it is good for the life of the vehicle. (Even though most other OEMs suggest, or require, changing it frequently.) For brake fluid they just suggest testing it every 2 years to determine when it needs replace. Not saying it needs to be replaced on a fixed schedule. It is, also, interesting that they don't have a single schedule for the A/C service, it is based on the equipment actually installed in a given vehicle.
It's probably the case. A bit annoying the price is almost $200 higher than the invoice posted earlier in this thread for same job.I believe it is because the system must be drained before the bag is replaced, then evacuated and refilled.
