Unknown clunking noise after exiting Model Y

[hoosker]

Just noticed this today while out grabbing pizza. I arrived, put the car in park and was walking away until I noticed it and had to turn around and grab a video.

I've made a service appointment to have it looked at but I'm unsure of what it could even be.

Check out the video and let me know what you think.

That definitely doesn't sound normal. Submit that video with your service request if you haven't done it already.

These cars can make a bit of noise all on their own, they have their own agenda to maintain.

Yeah, that ain't normal. Sounds like something trying to open or close and not succeeding.

I wonder if it's the louvers trying to open or close. After all you are in Detroit where its cold.

Does it do it all the time or was it just once?

I know it costs more, but switching to premium gas should stop that knocking.

I'm suspecting its the radiator fan assembly, looking at ebay posting of the fan assemblies, I see that there are metal clips on some of the fan blades, probably to balance it. I'm wondering if one of those moved or got loose and knocked the fan out of balance.

I scheduled an service request, included the video and what I thought might be the culprit of the sound. They actually sent back an estimate with the part I referenced. It is on order and will be ready for the appointment. I confirmed if the part is found defective it will be covered under warranty/goodwill whatever they call it. My appointment is Dec 27th bright and early at 0815 so we'll see how it goes!

I've heard it again today, seems to be when 'things' are winding down after I've parked and exited. It may have become pronounced because of the temperature drop.

Yes, they sometimes will give you an estimate before they determine it's a warranty repair.

Any chance some road debris has been pushed into the fan area? Are all the aero-panels under the car intact?

I did start off by looking underneath for any damage, All the aero-panels are intact. No visible damage present.

I have a similar issue and I don't see a way to attach the video to a service ticket. At least not on an iPhone. It filters out video when opening the photo library.

I upload to google photos and send share link.

I have just started to notice this sound.... just for a second at a time. In cold weather. I wonder if the car is 'rattling' the louvers to knock off ice???? Of if something is trying to open but is frozen shut or blocked with ice.

@hoosker Just curious about the ending to your mystery - did you end up going in for your service appointment? What was the verdict? I'm wondering, for my future knowledge, if I hear that same noise on my Y one day what I should suspect.

I pinged the SC and they said just mail it to them but I might send a link.

They bumped my appointment to a later date because of parts availability. However the noise has not returned. I originally thought it had to do with the temp drops, but it's been below freezing for the past two weeks now.

I'm apprehensive about going to the appointment without being about to reproduce the issue on the spot. Unless they can witness it, I feel like I'm gonna be SOL.

 

[Pianewman]

hoosker: I agree. Unless they can hear a problem, they won't do a service.

 

[DanDi58]

Did you send them a link to your video? I would at least do that. I don't think that noise, for that amount of time, is normal.
