I tested out the crawl control function on a parking garage ramp today and noticed a very unsual & dramatic vibration from the brakes in the low setting.
Has anyone experienced the same issue?

 

why are u using that on pavement. i thought it was meant for offroading

 

It is a good idea to check out all of the systems on the car so that you can address issues early with the dealership and not later when the warranity is void. The GX has so many features that it is a good idea to see how they work and become familar with the systems. Also, it is a good idea to test off road systems before using them on rough terrain. If there is a problem I would like to know when I am close to and a dealership and not out in the wild without cell covearage and freaking out what I am going to do.

 

I believe what you re experiencing is normal. I have a 2010 4runner Trail(same basic truck) with CC and tried it out in some deep snow here in WI over the winter. The brake pulsing is keeping you at the set speed and ATRAC may be working in conjunction also. Try the faster CC speed, less braking action

 

At higher speeds there is no problem. Thanks for your response.
