26-NA-049 and Service Brake Assist System

[dequardo]

I’ve had a ‘Service Brake Assist’ error message pop up a half dozen times in the past 6 months. Took it in today and they applied the subject titled software update. I can find nothing on the web at all about this. Anyone able to get these details?

Year, make and model of vehicle?

I did a brief search and found TSB 25-NA-049 involving an update, which applied to the. 2025 Equinox EV - I though perhaps your dealer listed the wrong number on the service invoice?

I have a 2025 Equinox RS AWD so your post was of interest to me. Perhaps the update is very new and hasn’t made it to the internet yet?

Well I think I have breaking new on this. See my post in the performance subforum.
