BlueCruise is dangerous

[roland farm]

I have a 23 Cal RT1 with blue cruise. As I am driving down the highway running at the posted speed of 70mph, my car suddenly brakes and slows down significantly. After this scary event has happened several times I have discovered that the blue cruise is picking up a 45mph posted on the frontage road. I stopped using BC for fear of getting rear ended and causing a dangerous condition. I did a quick search with no luck, am I the only one?

I’ve had the same experience

I set my own speed. I turned that off immediately. It was just annoying.

Turn off the speed sign recognition.

You can turn of speed-sign recognition and still use BlueCruise.

Turn off speed limit assist?

Oops. Echo

My MME (with adaptive cruise, BC not working at that time) slammed on the brake because it saw a stopped car waiting to make a left turn on the left lane. No car was in front of my MME.

Thanks folks, I'll look into the "speed limit assist"

If you don't want to turn off speed limit recognition, I just have learned where it tends to have issues, and am ready to nudge the accelerator to keep it from dropping speed much, then override the set speed limit. However, it doesn't have issues too often where I tend to drive, and is helpful to keep me from speeding excessively when I hit places where the speed legitimately drops.

When I click on speed limit assist it says, allows you to set the vehicles response to the posted speed limit. There is no on off button.

You still can use the accelerator...

i suggest consulting the adaptive cruise control -> predictive speed assist section of the manual.

I hate Bluecruise and will never use it.

Wrong setting, disable predictive speed assist.

You are not the first person in this forum to bring it up but that still doesn't change the fact that it is something that will scare the crap out of you when it happens. I happened to read about Predictive Speed Assist early on in this forum and that was one of the first things I disabled.
