Hood flutter w video

[dleepnw]

my hood has been rock solid with no flutter until recently. since day one it has been slightly misaligned when closed where the drivers side sits slightly lower than the passenger side. it didnt bother me from a visual pov and because it had no flutter when driving i left it alone.

im 18 months in and i started to notice a slight flutter. its hard to tell visually if the alignment has changed but im guessing it must have over time. i love having the powered frunk but i think the repeated usage and design has caused it to shift. not sure its worth having it looked at other than being concerned it might fly open or reduce my efficiency.

The adhesive they use has an expiration date so it’s not good forever and likely some production either had bad bonding foam or not enough applied. I’m waiting for more to be available so they can do the repair.

fixed it with this adhesive, they gummy crap the service center put on was totally useless and made it much harder to apply the correct adhesive

Huh, so I have noticed my LE R1T’s hood bounces a bit up and down at highway speeds but never really thought much about it. Now I am going to have to take a video and see from different angles. Question, what did you do, have the GoPro on a stick and had your window open? I was just thinking of sticking it to the roof looking down at the hood but maybe that wouldn’t show enough.

I stuck a go pro via suction cup on the fender pointing towards the hood.

also I just added some door stops where the hood bumper contacts the plastic (they are not long enough even full extended) this tightened up the hood but I have not had a chance to test it, I did run this by my mobile rivian tech who said it won't hurt anything. And I'm building off of the fact that one of Rivian service centers attempt to stop the hood from raising was to extend the hood bumper all the way (but it's nearly falling out and it still isn't long enough to make contact.

Adding these allowed me to move the bumper back in a few turns

this is just temporary as they are too big of a diameter and white so they are not aesthetically pleasing but I'm 99% sure this will make the hood very solid, you can feel a big difference when the hood's closed you can not move the corners nearly as easily.

Interesting others have attempted to have SC fix this. In my view it’s a design flaw by having just a center latch and the hood being so large. It certainly doesn’t help the leading edge is head first into oncoming airflow. I’ve never experienced this with other cars that have aluminum hoods. They solve it by having 2 latches - one at each side of the leading edge to keep the hood from flapping up and down. It is pretty distracting especially when there‘s glare coming up from the hood.

From looking at the gap increase in the OP’s video you can see the rubber seal isn’t making contact with the plastic body panel it closes onto. The only thing that might potentially help but won’t stabilize the edge flutter is to have the latch cinch the hood tighter down but then that would create a panel gap with the hood latching lower than the side fender edges. Still it will flutter at the edges torquing the hood as it already does given there aren’t 2 latches securing the two front corners of the hood to the body.

I have my appointment at the SC scheduled and they wanted a video. Mine comes up so much I am afraid moisture might enter the frunk in the winter. Check out the video. Does anyone else have this going on? What Fixes did the SC do for you! Thx!

nothing the sc did made any difference but the door stoppers I added where the hood bumpers touch completely stopped the hood from raising up, huge improvement I linked them here somewhere

Cool. Thanks for the info. Will see if they can figure it out. If not it is on to plan b. Your plan.
