Funny noise

Hey you guys, where I live there’s stop light at the top of a good size hill. It’s steep enough that my truck rolls backward a little if I take my foot off the break. A couple of times right before I hit the gas there’s a rather disturbing noise. Really hard to describe the noise but it sounds a bit crunchy lol. If I don’t let it roll it doesn’t do it. Anybody experience the same thing and should I be concerned?!

 

It's normal for the Automatic

 

Probably the sound of rolling over the car behind you?

 

Does it sound like crunching bones?

 

That's hill start assist control, the sound is the ABS pump doing it's thing.

 

i was hoping it was something like that but eff it’s an awful sound. Never had an automatic abs car or truck make that noise but it’s my first Toyota so I’ll take it. Thanks for the intell

 

those little mini coopers never had a chance..

 

My 2016 OR does the same thing at one hill in my town where I always get stuck at the light. I just bought the truck a few months ago from someone on here and it scared the shit out of me the first time I heard it.

 

Same! I’ve had mine 4 months and had many other trucks and cars that don’t make that sound so when I heard it I cringed out loud lol

 

My 4Runner did the same thing.

 

Like they said above, its the computer activating the brakes/ ABS module to keep you from rolling back too much. Either two foot it on that hill or make the brake > gas transition faster haha

 

I guess it’s a thing so no more roll back. Happy it’s not a problem

 

For sure, when I don’t let it roll back it’s fine or l just avoid the hill now lol

 

Never heard any noises like that yet from my truck, and i've stop on some pretty steep hills....truck will start rolling back if i don't bring up the idle speed. My gen1 tundra did the same.

 

i figure even if it’s “normal” if not letting it roll backward saves my ears from hearing that s*#t I’m fine with that lol

 

Sounds like it is incumbent to the OR/Pro brake system. My limited doesn’t roll back no matter how steep the hill is…and definitely no noise other than octane knock when I get going from a stop.
