Sorry to revive a year old thread but just picked up a used 2017 limited with just under 10,000 miles and I hear the slight "shhhhhh" sound on soft braking. I haven't attempted anything with ACC yet. Was it determined "that's just the way it is" or should I be bringing it in for service?

the only way ur getting rid of it is to change rotors and pads by ur own mechanic , the dealer wont do it, good rotors, pads, labor with set u back close to 500 so just live with it, i am
they have sound absorption panels but it doesnt help because its actually a vibration that is being transmitted to the body through the suspension mounts,
and from there it's amplified by the dash mounts nearby, chalk another one up to unibody construction,
proof: ul never hear it with the windows open, i tried at night on quiet road going slow
can only hear it with the windows closed, and it's is for sure the rotors cause if u get it even a little wet the sound stops

Gonna have to agree with iceman on this one. I have a limited and the noise started around 10000km. To me, it is minor noise that with radio on and kids talking, u won’t ever notice. Plus the fact that I don’t notice any degradation in braking ability, I am just gonna not think about it until the pads/rotors r ready to be replaced.

The issue is not old, i have a 2018 pacific and the same issue

Hi

I have the same issue and it started only at about 600 miles. I bought a 2018 pacific touring L and at just about 600 miles i started hearing the noise when breaking at slow speed in the city.

Its definitely due to low quality parts (rotors or pads) that is causing the issue. I now have about 5k on the van but wasn't sure if it was worth going to the dealership to see if they will replace or resurface the rotors.

But its not just the sound i do feel as the brakes do not respond as they were before the noise started. I have always owned toyota and honda's. Never have i had such issues with brand new car. specially the breaks on my current honda are crisp even after 2 years of use they act just like new. I also feel that the FCA dealerships don't give the service that i receive from the toyota and honda dealerships. Last i called them when my battery died for no reason after just 4k miles. They told me that they had no loner to give out and can't schedule me for 3 weeks so just leave the car with them. It seems like FCA has no loyalty program and is not concerned with customer satisfaction or customer retention.

At this moment this might just be my last FCA automotive purchase.

Is it worth taking to the dealership and what are the chances resurfacing the rotor will resolve it to some extent?

My van makes the shhhhh sound to on low effort braking. I suspect the ceramic composite brake pad material in the OEM pads. The rotors & calipers are manufactured by Brembo and are excellent quality. If this really bothers you, try and aftermarket pad.

My 17 TL+ has the same brake noise that started around 5k miles. It comes and goes. It seems like it's more severe after some highway miles.
I took it to the dealer for the first oil change last Saturday and asked them to look at (listen to) the noise as well and of course they couldn't hear or find anything. And they were not lying. I couldn't hear the brakes on my way home, either. Then on Sunday the noise came back...
I'll try to bring it in again when I can 'catch' the noise because brake pads and rotors are covered for 1 year and it's coming up soon.
If they can solve it under warranty I'll just live with it until I can't and replace the pads/rotors myself.

Brake noise on 2018 Pacifica hybrid plug in at about 3 k miles dealer replaced rotors. Had to take in 3 times!
1 didn’t want to do this work that day - even though I had appt
2 acknowledged problem after great effort at explanation - need to come back b/c didn’t have part
3 replaced rotor
NOW:
Another 3k miles in van. And the sound is back. Sounds like a grinder at low speed.
I am thinking this is a design flaw - parts inferior or underspec’d somehow.
Have had dozen plus vehicles and only one like this was a first model year Nissan Armada — it was taken back by Nissan as a lemon.
Guess I will return to dealer but the time commitment is very high and super frustrating.

I have had the same rubbing sound from the brakes from day 1 on my Pacifica '19 T+. Initially I thought it was the brake pads taking some time to get 'set', but after 4 months and 5k miles, its there every time I brake, especially at slow speeds. I have taken this to the dealer and they say/pretend they cant hear anything unusual, meaning, this is 'normal' and wont do anything about it since it is 'normal'. I have been to the dealership service department over 7 times now for another UConnect Android-Auto issue and the van is in the shop right now over the last 3 days. As for this brake noise, I just gave up. Its annoying, but so far the brakes dont seem to fail or perform badly, so I guess I'll wait till the pads wear out and replace them with better after market parts.
The dealership service is really pathetic compared to the one in the honda/toyota/subaru right opposite to them. While waiting for the shuttle ride back during one of the trips I heard another Pacifica owner getting ripped off by the dealer saying the ESS battery isnt covered under warranty after one year and charge him the full/premium price. So, yeah, i do have really low opinion when it comes to the chrysler dealership service, under warranty or otherwise.

When we test drove our 28k mile pre-owned 2017 Pacifica last August, I noticed that the brakes were a bit of a noisy, pulsating mess, but the rotors were rusty from the vehicle sitting in a humid environment (we had it shipped from Louisiana) so after a bit of driving the pulsation went away, but that low-speed noise never did.

The noise continues to this day. Last weekend at 44k I pulled the front wheels to take a look at the brakes. The only thing I really noticed was that the wear pattern on the rotor doesn't quite match the friction surface of the pads, at least on the inside pad on each side.





I wonder if in my specific case the noise is the brake pads hitting these rusty margins. With a road trip coming up next weekend, I'm biting the bullet and installing new pads and rotors tomorrow. I'll report back if there is any improvement.

Follow up and a possible theory on the noise. Please note that this is a sample size of one and may not represent a solution for everyone.


As mentioned above, I replaced my front pads and rotors today. Other than it taking a lot of beating with a large sledge to get the rotors loose, the job was pretty straightforward. What I did notice once the rotors were off is how much of the swept area of the rotor is rusty and not worn in like the rest of the rotors.





And the inner pads on each side have a corresponding stepped wear pattern. Additionally, if you look at the the back of the inside pads, you see that the width of the wear pattern on the front of the pad matches almost exactly the size of the pistons in the caliper.





The new rotors and pads definitely cleared up the low-speed grumble/grinding noise. My guess is that the brakes wear like this due toa combination of the smaller diameter pistons in the two-piston calipers and the choice to use of a thinner backing plate in order to accommodate more shims and anti-squeal provisions makes the pads transfer the hydraulic force from the pistons to the rotors unevenly. Not a safety issue, but an annoyance.

I Started having the shhh noise right after the dealer replaced my axle/hub for the common popping noise these pacificas develop.I have 47K. Dealer insists that its normal. One pacifica with 35k did not have the noise, while a New 2020 had the noise just slightly quieter shhhh than mine, so it is but isn't normal. They tell me its the actual brake booster making the noise and its normal but I swear its coming from the wheel and not above on the booster. Even after a rotor resurface and pads scuffed, the noise was the same. So could this really be the brake booster or the type of pads/rotors Chrysler uses from Brembo? I'm so annoyed and confused with this noise that wasn't there until after the hub/axle was replaced, I'm 100% certain it was not there. Whats everyone Elses theroy on this?
