When driving on the highway with ADAS on with lane keeping assist turned on with software 2024.39.01, the truck would constantly pull me back into the center line even if I were not close to the white line on the road. This is very concerning as on a two-lane highway, it pulled me over the center line and towards an oncoming traffic. The latest software update seemed to make it more sensitive, not allowing "ping-ponging" and trying to keep the truck almost too centered, as other cars I have are not this aggressive. I ended up turning off LKA, but that should not be the solution.

When it rains, or water is allowed to collect on top of the roof, water seeps in through the hinges of the driver and passenger sun visors. Depending on how much water is allowed to collect, it can trickle in or gush right inside the interior of the vehicle. Not only can it come in thru the sun visor hinges, but water also came out of my center roof console where my hazards and SOS button are at, causing me to worry about a water + electricity issue. Furthermore, the water obviously gets the carpeted floor wet. My truck is in the Van Nuys Rivian service center for the 2nd time for this issue. This is a well known issue on Rivian forums and on the Rivian subreddit.

I was driving to a restaurant and out of nowhere started hearing this metal-on-metal sound 1/4 mile before I got there. I pulled into the parking lot and it kept getting worse, so I called Rivian to tow the car. They confirmed it was a hub and shaft bolt that came loose. I have video of the sound it made if needed. The Rivian technicians took the pictures that I am uploading here.
