MarkG47,
Welcome to the Noisy Club! I looked at your video, but it sounds quite subtle. Do you have performance package on yours with Ohlin dampers? Here is my experiences of noises on my PS2. I had a kind of similar noises from the rear axle. When I talked to Polestar space, they suspected it would be a faulty Ohlin damper. So they took my car and diagnosed and found it was that damn dampers. They ordered new dampers and replaced it. The the noise went away! It took 3 weeks for me to replace, though... pain in ass. You might want to have the service check your damper, if you have.
However, even after replacing dampers, I still am dealing with bunch of different kind of noises from everywhere in my car, just in case you are curious~

Good Morning @fastiger thanks for the information. My car is Non PP. the noise is (in my opinion) from the drivetrain. It is faster than the driveshaft speed so i think it points toward the motor and gearing before final drive. I will let you all know what the garage say.

Got it! I am curious what is the issue and how they fix it. Let us know~ Good luck. 🤞

Hi everyone, I am also having a similar issue. I had previously mentioned this in an old thread before I was pointed to this thread. It sounds just like the first GoPro video in this thread that @MarkG47 posted.

In my case it sounds like it’s coming from the front drivetrain. Mine started occurring when I left a parking spot, I got about 10 feet pulling forward and heard a short metallic crunching noise from the front. Ever since this happened, whenever I am coming to a stop, I hear a faint “card in the bicycle spoke” sound just like others are describing. I almost always come to a complete stop using lift-off regen. I only hear this sound at slow speed when regen is active (with no music playing).

I have a non-PP (10 months and 8,000+ miles). I am 250 miles from nearest service center (waiting for one to open up in DC), so I haven’t contacted service yet.

I suspect that what you are describing is a different problem. Almost sounds like something mechanical broke - maybe you had a sticky brake pad (as discussed in yet another thread here), or something else failed.

It's open in Rockville now.

 

[Polestar_NoVa]

It's open in Rockville now.

Yes, I searched the forum a few days ago and realized that the service center was now open in Rockville. Thank you for letting me know though. I actually called them yesterday to make an appointment. They haven't called me back, so I will try again tomorrow. Also, after listening to the sound more carefully, it may actually be coming from the rear drivetrain like others have mentioned. Sometimes I have a difficult time with the direction of a sound from within the vehicle. I'll let you know if/when I find a solution.

 

[MarkG47]

Morning All.
This noise is proving to be a bit of a pain to track however the "good" news is that it is getting louder.
Over the past weeks i have been videoing with an external mic. I think i have tracked an area where the noise is clearest from within the car.
Long story short, i placed an external mic deep into the gap behind the rear seats and the boot (trunk) and its here that i get the clearest sound. Links to the videos below. I am waiting for Volvo service to get the Volvo Ear tool so that thy can basically do the same. Someone did suggest its bodywork creaking. Have a listen and let me know what you all think?

 

[PolestarMG]

Definitely the same noise I hear in my vehicle. Why would the bodywork freak only when decelerating at low speeds? I’m so curious to find out what’s really going on here and what the fix is.

So, I have had this same issue since mid-November. I finally booked an appointment at the new Washington D.C. service center and got the car back today. They removed and inspected the rear brake pads and rotors and didn't see any issues. Then they said that the right rear wheel arch liner was actually touching the tire and that this was the issue. Unfortunately, on my way home I started hearing the noise again, so I'm guessing that the trim is either touching again or that it was an unrelated problem. It makes me feel a little better knowing that they didn't see any brake issues, so I guess I will see what happens over the next few months or mention it again at my next service.

 

[ProfessorCook]

So I have this noise.

It's only while braking with regen and it's only at low speeds while coming to a stop.

It matches something to do with wheel speed.

It seems to come from the rear, right side of the car.

I'll check the arch liner, but I doubt it's touching only on deceleration.

Very glad for this thread and the investigative work so far. Thank you!

 

[Icesingh]

Hi I had a similar noise for the first time yesterday or just noticed it for the first time, but I have a LRSM, only at very low speeds.

 

[ALinSF]

I had a constant similar noise for about two or three months (plus a never-ending series of squeaks under all conditions). After two weeks at the dealership all fixed (PP with 4,400 mi and just over 12 months old).

Creaking sound was a broken driveshaft. Took about 5 business days 7 days to ship part to Marin, CA dealership. Took about 2 days to install and test. Creaking/snapping/metallic popping sounds all gone. Cause unknown. Service manager says "spirited driving" seems to be the most common cause. I conclude that to mean improper design specification for drive shaft.

Squeaking sounds were shock boots and they said it was fairly common and may return, but using an industrial lubricant different from the technical journal in the hopes the solution will last longer (TJ 35681.1.0 : Grease p/n 31437986). I also applied a teflon dry lube coating on all seals and bumpers on hatch, doors, hood from forum recommendations before taking the car in for service (which didn't solve my squeaking sounds, but I think it helped with possible other squeaks which were being drowned out by the shock boot issue).

Good luck in solving the creaks and rattles!

And so adding 50KW of power would do what???

Thanks for this update, @ALinSF. Was the driveshaft sound more a creaking, as you describe (which I think of in my head as like a door or floorboard creaking), or a card-in-spokes sort of sound?

I ask because I’m visiting Marin next week to have my passenger mirror looked at (seems to struggle to extend, I’m guessing a motor issue), and wondering if I should have them check out this noise while it’s there or if it’s a waste of time / seemingly normal feature of the car.

 

[ALinSF]

I would say door floorboard creaking sound may be accurate. The card in spokes would be too low frequency for what my sound was like. It was like a higher pitched metal on metal creaking. In my mind, it sounded like an old fishing boat creaking while docked in an area with somewhat constant waves. The tech called me within two hours of dropping it off and said he found the driveshaft had a visible crack and was extremely confident that was the source of the sound. You are going to Marin, so Alex is the person to talk to. You should have them check out the noise because you and I are not the only ones having some of these noise issues and they are getting better at figuring them out. Just like the shock boot squeaks cannot be solved long-term with certain lubricants and they are finding better ones. It's only been a year of history, so I'm sure they are learning some of this as they go along. The damper shock design is not a standard Volvo set up so they are going up the learning curve too.

One disappointment was the lack of loaner cars. I'm assuming most drivers don't live that close to any service center in the early days of PS, but if a driveshaft breaks and takes a week+ to order/repair, I think some kind of loaner should be found.

Got it - thanks! That does sound like a different issue, but I’ll ask them to check out this noise anyway.

FWIW I’ve had my vehicle in to Marin probably a half dozen times (but not in the past 6 months) and haven’t had an issue grabbing a loaner, though it’s possible they’re running low with more cars now on the road.

Same issue here. Rear passenger wheel starts thumping when letting go of accelerator at slow speeds using regen braking. Started today as far as I can tell. Working back with Marin. Seems like it is a common issue, but mostly affecting those that are hearing it and attentive to it. Hoping one of us will update as they address it.

 

[JRRF]

Is this only a PP issue, or have others heard it too?

 

[Polestar_NoVa]

Is this only a PP issue, or have others heard it too?

I have a non-PP and I have had the issue (card in spokes) since mid-November.

 

[PolestarMG]

Non-PP here also. For all we know it’s not an issue, but it seems like nobody has really got an official answer (or clear diagnosis) from Polestar.
