ECU Bricked during Recall Update…

[lingyunly]

I sent in my 2021 Supra to the dealership yesterday for the recall. They spent an entire day on it and told me today that, after a long call with Japan and Toyota engineers remotely taking over, they couldn’t do it and basically my ECU won’t “take” anything now. So basically it’s brick. The car is dead, can’t move, can’t do nothing, until they get a new ECU. And of course, the ECU is on national (or global?) back order, so I’ll have to wait who knows how long.

The dealership was pretty good regarding other things that they did on my Supra so I trusted them. (See my other post about the jammed hatch). They said they did the recall on other Supra(s) before but don’t know how things got wrong this time.

I was lured by the supposedly full screen carplay. Stupid me. Now my plans for the last couple trackdays in the season are all ruined. Just put new RT660s on and got new pads ready to be installed.

The only plus is dealer offered free loaner and I picked a 4runner. From the small sports car to that big ass truck!

Anyone experienced similar issue during the recall?

Can't @Marshall@ViscontiTuning fix that?

Ecu bricked or headunit bricked? Sounds like dealership messed up during the update. There is a specific procedure they have to follow to the T.

Man, this sucks. I feel HORRIBLE for you, and truly appreciate that you're being reasonable with the dealer about it, because I'm sure they're internally irate this happened, and in crisis mode with Toyota.

Keep us posted on how this goes.

If your dealership begins attempting this update without the car being on a battery tender, stop them.

Only a Master Technician with Supra Certification can perform the recall, so they of all people will know about the battery charger/tender requirements. I don't see how that mistake could be made.

I'd bet a beer that's what's causing these.

RIP to another Supra. This is the scenario I’m dreading. A $60K door stop for trusting the damn dealerships.

Sorry dude! I got super concerned about mine cause it took them ALL day, then they said they had issues and needed to keep it over night. Luckily they got it done and I was all set the 2nd day, but I was super worried.

Could you snag an ECU from one of the wrecked Supras in the salvage registry?

This is why I’m waiting until after the last autocross and just before I put it away for winter. So around December if I don’t decide to skip it entirely.

Are they going to allow you on a track without the recall being done? NASA sent me an email a few weeks ago saying I would need to awknowledge that the recall will or has already been performed prior to my track day.

I do autocross only now. We aren’t that concerned.

I heard a few dealerships were turning off the scan tool to reset them during the updates and messed up everything.
It’s like when your smart tv is updating and there is a warning sign saying not to unplug…
