Automatic Vehicle Hold Disabled Alert

Has anyone had this alert show up? It sure changes the way you drive the pickup. I have a service request to get it addressed but was wondering if any one knew what causes the issue.

I just had this pop up on mine near the end of a 100+ mile trip. I got home, charged it up just part way, checked on it tonight and the alert is gone. "There are no active alerts".

Did you learn anything about this? Curious what I might be dealing with.

Thanks

Yes, I did have it in for service multiple times. After a couple visits, they replaced the following part.

MID VOLTAGE REAR CONTROLLER(1810836-12-D)

That worked for about 5 months and it came back again. It was intermittent but still given they have a complete log of the errors and it is a safety issue, it needed to be resolved. They said it was the right rear parking brake was not working properly so the replace the whole caliper assembly. That was about a 2 weeks ago and it seems to be corrected for now.

Thanks for the update. Hopefully that fixes it for you.

Similar issue, going from Park to Drive or Park to Reverse... the rear driver side parking brake would make a loud grinding sound.

Technician detected low voltage in brake circuit and diagnosed it as bad rear parking brake caliper and replaced both rear calipers last week. Drove it 400+ miles and issue didn't return.
