Here we have the second service bulletin this year regarding the ongoing struggle Toyota has with their connectivity tech. In my case, the dealer did not bother updating the firmware before turning my 2020 XLE over to me, and I wasted hours on the phone with Toyota support, and four trips to the dealer, and now still have no functionality for remote start or status, either with the keyfob or the app.
Adding insult to injury, this is the service that TMC wants us to pay them for every month - even keyfob functionality for remote start is tied to a paid service subscription. I'm curious if anyone else is harassed by this situation? How do you feel about paying monthly for the app?

I've had the exact same issue on my 2020 RAV4 and that same TSB supposedly applies. They replaced my DCM last Friday and as of today it is still sitting at the dealer non-functional with no promise of when they will figure it out. I am still in the free trial period but would NEVER give them a dime for their remote connect or safety connect. Toyota tech is completely incompetent in dealing with connectivity issues and they won't even cooperate with their own dealers. They will give you a case number and promise to call back but never do. Before they messed with it, my remote connect would not start the vehicle but at least it would lock/unlock the doors and tell me where it was parked. Since they replaced the DCM-nothing works, including the Toyota app. If I know then what I know now, I would just ignore the remote connect and safety connect. I can't wait until I get my next Consumer Reports member survey where they ask for experience ratings on your vehicles. I would give Toyota a negative 10 on their connectivity/tech quality.

Thanks for sharing. The firmware update in this years first TSB, after much hassle, got the app to work for me. The key had been working for remote start from the get go. After a month or so, both app AND key functionality was lost. What changed? No clue.
I've had better luck with the corporate customer experience people, they always follow up as promised. The dealer seems both careless and clueless.
The customer experience people said they couldn't extend my trial period (I asked for that so they could prove there was something worth buying), but they picked up a car payment for me by way of recompense.
The key functionality should be free IMO. Beyond the tech problems, they are making a bad customer relations mistake by bundling key fob remote start with the subscription app services.

I have a 2019 RAV4 XLE hybrid. The first time the battery died was May 2020. The second was December 2021. Toyota service said there was a tracking device factory installed that was drawing power (even though we don't subscribe to the tracking service). They removed it and I hope that fixes the problem. I asked them about the TSB 0095-20 and they said my VIN wasn't in the TSB list. THere are plenty of others posting with the same problem at Car Gurus https://www.cargurus.com/Cars/Discussion-c29023_ds1091695

This is most startling. Can you please post more details? What
dealership did this work? Did you get a service receipt describing the
work done? Did they give you the "removed" part? Photo? Thanks.

The DCM module does this. Read up in your owners manual. Yes if it’s ON then your being tracked and Toyota sells the info. Some folks opt out but you lose several potential safety related functions.

Some regions install the "TheftPatrol" unit at the port.
This is effectively a Lojack, and if you pay the subscription, they create an account that allows you to monitor and track your vehicle's location and other functions such as 12v battery state.
If you don't subscribe, the device is not removed.

It also helps the dealers if vehicles are stolen from the lot, and you may be able to get a break on your insurance rates.

"They removed it" would not apply to the DCM tracking... that would have to be a 3rd party unit such as Lojack Early Warning, TheftPatrol, or some other similar system.
