Sure its not the pedestrian warning noise?

 

No its a grinding sound.

 

The pedestrian warning noise makes our Venza sound like an alien space ship pulling into and out of the garage 🤣

 

Agree! I’m getting used to it.

 

can you post a sound clip?

 

I have not been able to record it yet It happens so quickly.

 

First, if the vehicle does this all the time, take it to the dealer, take one of their staff for a ride and reproduce the problem. A verbal description isn't adequate. If there's something wrong, you want it fixed now, before it becomes a bigger problem.

1) Wind down the front window. When you're on a turn, is it coming from the inside wheel or the outside wheel?
2) Does it make the sound for low-speed turns, high-speed turns, or all turns? (Note 1)
3) Look at your brake rotors in the morning. Is there surface rust on one or more rotors? Especially look on mornings when it rained or the humidity has been high? If there is rust, do a couple HARD stops in a straight line so you KNOW the brakes are doing the stopping. Does the sound now go away when you're turning? (Note 1)

(Note 1) Since hybrids also use regenerative braking, the mechanical brakes don't get used nearly as much as conventional vehicles and rust accumulates on the brake discs. I believe the Venza uses differential braking for slow-speed, tight-radius turns (part of the vehicle stability control - VSC). When the brake pads lightly contact a rusty rotor, they make a grinding noise until the surface rust wears off.

 

It only happens a few times a week.

 

If it only happens when your foot in on the brake it's probably the anti-lock braking system. I've noticed this on mine and I believe its caused by the brakes being grabby. This locks the brakes briefly and activates the system.

 

Did you correct it from happening?

 

There's really nothing to correct. It doesn't hurt anything and the system is performing as it's supposed to. The brakes on this car are very good - maybe too good. If you think it's dangerous have the dealer take a look at it. See if any adjustments are needed.

 

Are you driving on a loose surface like dirt or gravel when the noise occurs? Are you gently applying the brakes or braking hard? Do you also feel a grinding or rapid pulsing through the brake pedal?

 

I driving on paved road and gently on the brakes grinding noise only foe like a second or two.

 

If it only happens once at first use of the day, it's caused by surface rust on the brake rotors which develops overnight as AJMiata mentioned, once the friction brakes are applied it disappears.

 

My wife reported this same grinding noise recently. It has happened TWICE now, both times in the same exact spot on her commute!

It occurs when braking normally and turning right into a short, somewhat tight low speed turn. The noise scared the crap out of her. One time it occurred at the beginning of the turn / early in the braking process and the other time was near the end of the turn / end of the braking process. The noise only lasts for 1-2 seconds.

Below is a picture of the turn and the locations along the turn the noise occurred.

Just under 2,000 miles on the car and this is the only 2 times it’s happened. I am thinking it’s some fringe condition that is invoking ABS or stability control. Will keep an eye on it and engage the dealer if it continues.

 

That's what happens to mine

 

This happens to my Venza as well! The grinding on the turns and then sometimes braking going straight more of a clunking noise. I have complained to the dealer, and next service I will try and get them to look again. Glad I am not the only one who has this problem, everyone thinks I am nuts until they hear it as well. Let me know if you ever find anything out!

 

my 2021 venza has also done that a few times it felt as if the tire was coming off had to stop and look not sure what it is, drives fine after that

 

Heard as well on my wife’s Venza. She was going slow on a gravel side road. Dealer thought it could be the sensitive anti-lock brakes which makes sense since in both instances she was lightly using the brakes. so when you hear the noise are you using the brakes on an uneven surface? Is so could be the anti-lock brakes which is a rattling type noise.
