Software update causing Brake Override light and “limp mode?”

2019 TRD Off-Road double cab long bed

First time posting here…


Light came on, truck lost power, stranded in the Sierras; tech said it was caused by a software update that was needed. I asked “was it something that I missed?” He said no, I wouldn’t have known about it, so I’m like, what the hell?

Has anyone ever heard about this? He said it was under warranty so I didn’t pay a thing, but something doesn’t feel right about it.

2019 are constantly connected to Toyota unless you specifically tell them to disconnect it. Even then I suspect they still download data from your vehilce without telling you. With the connection Toyota can push upgrades out unknown to you when ever they want. That's probably what happened. Once the remote update failed it probably required a hardwired connection to correct the upgrade process.

Interesting. Thanks so much!
