I guess my 2024 is not affected.

Well this recall sounds pointless.

 

[BackToBlack]

Base model No navigation has that too?

 

[Mori]

Anyone know if they do a full ISTEP update or only affected modules?

 

[Vertex]

If it's anything like how the subaru one works, it should only affect the module directly

 

[PureDrifter]

Wonder if this will fix the stupid useless wireless charger from overheating the crap out of phones. I remember that it's got a cell repeater built in.

LOL, dealer called me to tell me there is a new firmware update just released and wanted to delay my servicing. If this is all it's for, they can just skip it.. Incredible it's considered recall worthy.

Just unplug the DCM antenna anyways, its just sending your cars data to insurance companies anyways

Originally I said this recall was pointless but maybe not. They seem to be in no hurry to fix the throttle hesitation issue. So might as well make sure the people who get T-boned because of it are in fact able to make an emergency call afterwards.

Just got this in the mail, I guess I'll book this with my yearly service next year?

Is it really a problem? I'd almost prefer if the car couldn't communicate back with Toyota tbh ?

 

[Supraluv]

I took mine in for the update and it doesn`t work as of yet.They will call me when Toyota gets it figured out.

Maybe a dumb question but when they do this update will they be flashing my ECU or anything like that? Don’t wanna mess up my tune.

I do believe they will, any unlocked ECU they will likely relock...
