At low speed when I first push or release the gas, I hear a click sound like it is in the dash. Has anyone noticed this? The van operates fine, but I notice the little sound at times.

I've noticed the same thing. Usually between 20 and 45 mile an hour most noticeable if you're in stop and go traffic accelerating decelerating. It sounds like slop in the driveline. It's been a while but I believe my dealer reprogram the transmission slow lock up torque converter when that engage at low speeds which helped reduce the shock of being on and off the gas again. I just bought my third limited with 125,000 miles on it a few weeks ago. It sounds just like the first 2017 I bought with 18,000 miles on it. I believe my second 2018 Pacifica was the one they reprogrammed and it seemed to make it better.

I'm learning to do that a lot with this van, prevents my anxiety from flaring up when a new sound pops up.

I'm chiming in because I have a gas only model and I hear the same thing. Either a clicking or a buzzing noise when lightly stepping on the throttle. Almost like the electronic throttle control making the sound.

I have 2022 pacifica hybrid just 3 months old. I have started noticing a clicking sound when putting gas on and off at low speed. I went to the dealer service and they said its common because the electric motor in transmission has magnets and it does. While in off position and in parking he push my vehicle front and back little and we heard the noise click click from the front passenger side. I am still not convinced with the magnetic motor theory, as this sound is keep disturbing me always as now I know that the sound is there. Earlier, I didn't notice this so I am not sure if this noise was always there or not. Any suggestion is highly appreciated.

My 2018 gas touring L (w/48,000miles) is also making that clicking/slop/loose sound at low speed between 30-40mph, and it's driving me crazy. I recently drove a 2021 gas Pacifica with 3,300 miles for 10 days and did not notice any clicking or slop sound. So it makes me think it is NOT normal. I will be checking my axle nut when I get a chance. thanks @lacompas

I found a few TSB, one that include my build dates, which makes me think this might be related to premature wheel bearing failure.

I know a worn bearing can loosen an axle nuts, and a loose axle nut can cause axle clicking. So I'm keeping an eye on mine for signs of wheel bearing failure.

I know that is I fully crank the steering and drive slowly in circles, the driverside is slightly noisy. The tech mentioned that if this happens it could be bearing related. I hear no noise at high speed though. Anyways, I'm just monitoring for now as the noise isn't so bad.

Interesting. i have a creaking noise when i crank the steering wheel all the way to the right and reverse. now, i sometimes get a slight creak when at full crank to the left and drive forwards quickly from stop (like when you you pull out from street parking).
what are signs of a premature wheel bearing failure?

Usually the signs are a howling sound increasing with speed. This sound will change when turning, due to sideways forces applied to the bearing. Sometimes you can hear it by spining the wheel freely (non propultion wheel) or by feeling looseness in the wheel itself when the bearing is really shot.

But my tech also mentioned that you can also tell by sound slow tight turns (forwards or reverse) and listening for grinding noise differences between sides. Mine only does noise in those slow tight turns, but it almost sounds like the brake pads sliding on the front disk.

Creaking noises you mention are most likely not wheel bearing, but maybe upper strut bearing, control arm bushings, swaybar links or the TSB for the knuckle creaking.

I updated in other threads, but sharing here for completeness:

My issue came back a few months after replacing the axle nuts. The dealer let me drive a brand new 2023 PacHy on their lot that was worse then mine, so they said no point in replacing parts.

So the replaced both axles nuts again, over torqued them slightly and added a second nut on top to lock them in place. They marked the nuts to see if they ever come loose again.

It's been quiet ever since. Will update if this issue ever comes back.

I never noticed this before but after reading this thread I did notice this noise when I moved my wife's van into the driveway the other day. Unless it changes and gets worse i won't worry much about it.

I have a 2020 Pacifica with 45K on it. Purchased it used at 32K and do not recollect hearing this click noise. Think it developed overtime and now there is small jerk associated with the clicking noise. I plan to take it into the dealer next week. Lets see what they say. Glad i could reach here, I was questioning myself if it was normal for a Pacifica Hybrid as I only feel it at lower speeds and with EV only mode.

2021 limited 54k KM now, had exactly issue since about 30k KM, this click sound is getting louder and noticeable. After I read this thread, i thought the axle nut must be the root cause because the issue description is 100% match mine. Next, I bought a 34mm socket, open the wheel center cap of both front wheel, and turned out both nuts are tight and secure nicely. I can not screw in the nuts any bit using the socket and extension bar. And guess what, even i did not able to tighten the nut any, the click sound is gone. It has gone for 2 days. I will keep observe and update.

2019 gas Pacifica L Plus with 49K miles, just started noticing this issue today while taking the kids to school driving around 30-40 mph..
I was trying to figure out if it might be the transmission, steering rack, Axle related or pedal assembly lol.
Really glad others have already replicated and documented the same clicking noise/feel on the gas pedal.
Looking at the previous posted axle pics, I found it odd that it doesn’t contain a groove for the Axle nut to be staked on like on my Honda/Subaru cars.
So are we 100% sure the solution is the Axle nut coming lose and it needs a 2nd one to secure the 1st one that is torqued?
Wondering if anyone has had the noise/feel come back after adding the extra axle nut?
Thanks in advance.
PS: I remember my 2005 Subaru Outback axle nut torque being around 137 lb/ft, 120 for the heavier Pacifica minivan seems kind of low..

Only one person has done the second axle but after repeated trips to the dealership. Of note is they used a different beefier axle nut on top of the OEM nut. Locktite failed, over torquing failed, but double nut fixed it (for @lacompas).

My dealership replaced and re-tourqued it twice. They said they will look into the double but if the current torque fails.

Thanks for the clarification SitKneelBend.

And when you say the axle nut has been replaced twice, was it because of the issue described on this thread or because some other related service by the dealer where they had to replace the axle nut and therefore they had to place the beefier nut subsequently to better secure it?
Maybe it’s just how I read it, but it would lead me to think this axle nut getting lose so often can be quite a serious issue.

Does anyone have the Axle thread pitch/size or a link to that extra heavy nut which secures the axle nut?

I’m honestly surprised Chrysler doesn’t already have a SB for this problem.

Chrysler has a TSB that covers this but only for AWD Pacificas. The picture of the doubled up nut is from forum member @lacompas 's Pacifica. Mine still has just one on each axle as the dealer service said they have to go through all the steps with no particular TSB for my 2022 Pacifica Hybrid. I'm letting it play out as I have the time to do so but if I take it in again and they don't double it up I will by the parts myself and do it. The nut takes a 34mm socket. I bought this...


No Idea on threads for it but mine were replaced originally when the entire transmission and half axles were replaced earlier this year for a separate issue, 3 weeks later the noise returned, I tightened the nuts myself and the issue disappeared for about a month, and I had them address it with another issue I needed the dealership for last week.

Ah ok, I see. As for myself, I just started noticing/feeling the clicking/tension issues on the gas pedal today, I was like "what the heck is that"? Trying to associate it with what it could possibly be, thinking something was broken..

I guess for it just being an extra axle nut we have to add, it really isn't so bad in regards that no major components have to come apart and such.. (like that Radiator I replaced earlier this year), over a hundred bolts/screws/clips and other components to remove for just a radiator..
On my Subaru Forester it's just 8-9 bolts, unhook a couple of hoses and the whole thing comes out.

Anyways, I was wondering if they make a self locking nut in that size and maybe adding some blue Loctite to the axle threads for extra security, not sure it that'd be overkill, but heck, if it was up me, I'd even add safety wire like they use on planes to secure nuts.

I'll report on the threads info once I research deeper into this.
