key fob/connected app failure on 2022 RAV4 Hybrid Sign In

This is a new 2022 RAV4 Hybrid with 350 miles on it. Made in USA. The vehicle has a smart key system for locking/unlocking and starting. The system includes two key fobs and a connected app that can lock/unlock and start the vehicle. The car also has a touch sensor on the door handle to lock/unlock the vehicle when the key fob is present.

Two scenarios/types of behavior:

1. After driving, vehicle won't lock/unlock with anything but the hard key (fob, door handle touch sensors, connected app, interior lock buttons don't work). Issue appears to go away after restarting vehicle. Other electronics work when this happens.

2. After being parked for ~1 to 24 hours, the vehicle won't unlock or start at all. The only way I've been able to "reset" is to attempt to shift out of park, which activates the alarm, which reactivates the fob/connected app.

During both scenarios: cabin lights work, some dashboard indicators work (like door open/closed diagram).

App error message
If I try to lock/unlock or start the vehicle with the connected app while this issue is happening, I get the following error message: "2022 RAV4 Hybrid: Your request could not be completed due to a communication error. Please try again later. [C2]"

Issue history

The first time this happened, I was trying to drive the car off the dealership lot and it wouldn't lock/unlock or start. The dealership said they reprogrammed the keys and that it solved the issue.

Then, a few days later, I had just finished a ~10 mile drive, turned the vehicle off, and was trying to lock the vehicle by pressing the touch sensor on the door handle and nothing happened. Then I tried the key fob and nothing worked (lock/unlock, lift gate, alarm). Then I tried the lock button inside the vehicle and it wouldn't work. I was able to restart the vehicle by pressing the start button, after which the fob worked again.

A few days later, the vehicle had been parked for 12 hours outside my apartment (I live in California and temps were about 50 degrees overnight and 60 during the day). The vehicle wouldn't lock/unlock or start. I could only resolve the issue by attempting to shift out of park, triggering the alarm, and then using the fob.

Both of these types of scenarios happen several times a week.

Things I've tried
Disconnecting 12V battery for an hour and overnight

Checking 12V battery health

Starting with just 1 fob present

Starting with both fobs present

Re-installing all apps

Reprogramming keys

Touching fobs to start button

Dealership involvement
I have taken the car into two different dealerships three different times.

Most recently, the vehicle stayed with them for 10 days, during which time they supposedly turn the vehicle on/off and locked/unlocked multiple times a day trying to recreate the issue. They weren't able to.

The dealership submitted a ticket to their global system to see if they could find a similar issue but found nothing.

Both dealerships have suggested that it's user error and that I should learn to use the key fob better.

One of the techs at the dealership that I spoke with suggested that it could be interference from something like 5G and that I should consider getting a new set of keys programmed to the vehicle. When I suggested this to my dealership service rep, he said "not unless we can observe the issue".

Please help!
I don't know what to do at this point. I still get the issue regularly and don't know how to help the dealership observe it.

I'm thinking about buying a diagnostic tool so I can get a snapshot of the system when this issue happens, but I know nothing about car diagnostics. Would appreciate some guidance in this area.

Thanks in advance for your help!

You don't have any options here. Your vehicle is under manufacturer's warranty and they are the only ones to fix this. You have to avoid tampering with it now or they will have an excuse to void your warranty.

Since your door locks don't even work from the inside switches, the remotes are not likely the problem. It sounds like something is going on with the Body Control Module.

do you know if running diagnostics myself would constitute tampering? If so, is there a better way to document issue? Maybe record it with video?

There is no way you have the required equipment to diagnose this issue. Even if you did, you would likely erase critical info to help the dealer with his diagnosis.

Supplying the dealer (tech) with as much info as possible as to any warning lights, what functions die, in which situations and any particular locations that it happens. What restores the functions. All this info should help them isolate what is common to these functions which right now sounds like the BCM.

No need to read this. TAKE IT BACK, IT'S NEW!
IF YOU MESS WITH IT ANYMORE YOU WILL OWN IT. IF YOU KILLED THIS THING ARE EVEN LIABLE TO PAY FOR IT.
STOP NOW IF NOT TOO LATE,

@Tom Greenleaf, I haven't done anything to it other than take it to the dealership three times. They insist that they can't re-create the issue and that they have to be able to observe it to either fix it or begin the process of replacing it. This is where I'm stuck now – it happens to me regularly but techs at the dealership aren't able to get it to happen.

The Toyota care that plan that comes with the new vehicle offers complimentary towing. Maybe I'll have it towed back to the service center when it happens again rather than fixing it and driving it in.

That would be the smart thing to do.

As a tech I can tell you that finding intermittent problems can be a nightmare and the flat rate techs at the dealership don't have incentive to spend a lot of time looking.

Tom – THANK YOU! I'll keep your marginally alive spirit in mind the next time I bring it in. I plan to bring documented evidence of the issue and more resolve in the face of a blow off.

Yeah, that makes a lot of sense and I totally understand. For what it's worth, the techs I've spoken to have been genuinely interested in the problem but at the same time have not been able to re-create and don't have the spare time to stay with my car all day long waiting for it to happen. Towing the disabled vehicle will hopefully help.
