Shaking sound when going over bumps

Hi,

I'm not totally sure how to describe this but when I drive over a significant bump (recession in the road or even a sticking up manhole cover) I think I hear a slight shaking sound. Hard to articulate a sound but I would say more like a shake or wind noise sound than a hard rattle. And as the driver it sounds like it's coming from the airbag pillar to my left (above the seatbelt section).

Anybody else notice anything along these lines?

Thanks.

Actually I think it's related to the top corner of the door (near the pillar). It seems like the door seems to not fit very tightly there and shakes a little and gives a little bit of exterior noise when going over bumps. The black rubber around the door doesn't seem to be very well glued onto the actual car frame.

Anyone else see issues with a solid, tight fit of the door (my issue is the drivers door) at the very top back corner?

Will have to take it in to the dealer to see what they can do about it I guess.

Definitely take in to them. That doesn't sound like a major safety concern or anything but it's hard to tell at this point.

I think it's just the rubber seal between door and frame. When going over bumps the vehicle (by design) twists and torques a little bit and I think it's just the two rubber seals vibrating against each other.

Dealer "lubed" which did nothing. Might have to look into doing a "home job" by putting some insulating tape on it if it doesn't eventually go away by itself (or I just get used to it).

That's kinda odd though.. but if the insulation tape would work, definitely let us know.

It might help to ask the parts desk guys what type of glue is used since when filling out work orders, they are the ones handing over glue with the rubber. That just might help give you a starting point for getting something better.

I can't work it out. I just need to turn on the radio and forget about it I guess. It's a very very minor sound only when going over bumps. And totally impossible to hear from the back seat even with your head right up behind the driver's head-rest.

But it does seem to come and go which makes me think it's something to do with the way the door rubber was positioned when it closes, the temperature and hence the stiffness of the rubber, or maybe it's something else. BTW if you look, on the doors the rubber is actually intentionally not glued down in the top corner. I checked with the dealer that is by design.

Anyway, I'm probably just too sensitive as this car is my brand new thing. I guess I just need to relax, enjoy, turn on the radio, and not be overly sensitive of every little thing.

Upon close inspection, there were several places where the driver's side door didn't look to be on as tightly. Therefore took it in to the dealer today and had the door tightened. Haven't driven it too much since then but that might have done the trick (fingers crossed - hopefully I'm not jinxing myself here).

Also was missing a brace around the front driver's side wheel (the 1" of trim that tucks under the fender). It was looking a little warped in one section - a non-visible brace (apparently) needed to be added which fixed that.

Finally, the running board trim (the flush piece of black metal that goes in lieu of full running boards) wasn't threaded properly at the front. Had them re-attach (properly) and screw back in.

So, missing braces under the fender, non-threaded faux/flush running board cover (not actual running boards) and doors that aren't sufficiently tight - makes me wonder how they're assembling these things in China!! What else is "missing" or "not screwed in properly" under the hood or somewhere else I don't notice it or hear it!?!?!

With how much I hear of new cars with issues like this I bet a business can be started just on these issues and surely people would spend the dollars required. It seems like we have to spend some big money to get some real build quality from car makers these days. Sad it has come down to that.

My 2016 Prem ll is very solid and quiet. Even when jump the railroad tracks near work.

Though the door close nicely but tend to bounce off the rubber molding.

Does yours have the pano moonroof?

Huh? What exactly do you mean there? (BTW, yes I have the moonroof)

I have a Premium II with the moonroof, and I don't notice "wind noise around the doors", like some apparently do. However, going over bumps is noisy. I hear tire noise, which is probably unavoidable, and what sounds like something loose in the back compartment, although I have looked under the hatch cover and don't seem to see anything that is loose. Test drive didn't reveal these problems. Demo was quiet riding, but I guess I will have to dig deeper into spare tire mount, jack, etc. to see if I can find source of the noise when going over a bump.

The rear headrests have some play as I usually try to keep them all the way collapsed when no one has been in the seat.

On a previous thread I described a noise that developed on my 2016 Premium II at about 10,000 miles. It sounded like things in the back were loose, but I could not find anything. Happened most of the time while driving on a variety of roads. Left it with my dealer, and they test drove it, and amazingly it was found. The fix was removing the entire left rear seat and adding some type of insulation between the lower seat metal frame and the floor to which it is attached. No noise since after several thousand miles.

Interesting how we pick up mew noises that were probably there the whole time.
