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.

On multiple occasions I have experienced the defrost feature of my 2023 Rivian R1T blowing cool air instead of warm or hot air, leading to a build up of ice on the windshield while driving. I have brought this concern to Rivian's attention with two service appointments, both of which resulted in Rivian noting they couldn't see any errors in the vehicle's diagnostic logs. I specifically noted the date, time, and temperature of one event but Rivian failed to copy the log data when requested.  The issue is trivially reproducible in temperatures around 32ÂºF, when the defrost mode is enabled. Tapping the defrost/defog button on screen twice to enable defrost mode results in the vehicle selecting the vents for floor and windshield heat, speeds the fan to near maximum, and is supposed to blow hot air to aid in clearing built up ice. Instead what happens is the vents blow cool air for several minutes at maximum fan speed. Then the fan motors slow to their slowest speed at which time the vents blow slightly warm air After 5-10 minutes the fans speed up to maximum and the air coming from the vents is cool.  When the vehicle was initially purchased, the defrost feature blew air hot enough to nearly be uncomfortable on the face. This is very much in line with any other vehicle I have owned when the defrost temperature and fan speed was set the maximum. But after an end of year update in 2024 or early 2025, the defrost feature began blowing cooler air and has never regained its original ability to clear the windscreen. The winter of 2025 and early 2026 has now resulted in this complaint.  Rivian maintains the system is functioning as expected, but the service center staff doesn't quite seem to understand the severity of the issue. They claim a bug report can not be filed with Rivian until they capture an error in diagnostic data that they repeatedly fail to collect. Instead their advice is to enable cabin vents to warm the cabin instead of the windshield.

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.

My truck was recently upgraded to software version 2050.38.0.  After the upgrade, I drove my truck about 3 miles in about 5 minutes.  When I arrived at my destination, I exited the truck to get something out of the rear seat. The rear door was locked; this is normal.  I returned to the front seat to unlock the door via the control panel, but the unlock function did not work.  The button is in the center touchscreen of the truck.  I check the screen on the center console. It appeared the unlock button was disabled due to the information screen from the code update.  This screen was not there when I exited the truck.  After I acknowledged the screen, the unlock button was working.  If I were trying to unlock the doors due to an emergency, this delay would be an issue. I feel the unlock door button should always work. Disabling the button for a verification screen is a safety hazard.
