2024 RIVIAN R1T

While traveling at highway speed on Interstate 95, the vehicle experienced a complete and sudden loss of propulsion. The vehicle would not respond to the Vehicle Restart function. The driver was able to safely pull to the shoulder from the right lane. The vehicle was towed to a Rivian service center, where technicians identified a low-voltage event matching a known Rivian engineering investigation. Rivian confirmed no current repair exists and that engineering is actively working on software improvements. The vehicle was returned unrepaired after 13 days. Rivian also replaced the 12V battery under warranty at a prior service visit in July 2025 for a related electrical system defect. Two field service actions (FSAM-1507, FSAM-1794) have also been performed on this vehicle.

Vehicles Steering wheel shakes when traveling over 20mph. Dealer has reproduced the problem multiple times but insists it’s a “design limitation”. The shaking can cause loss of control of the vehicle. Dealer refuses to investigate further. This has been occurring since day of purchase.

The entertainment and gauge cluster displays begin to slow down and stutter, eventually leading to a full reboot. This causes the ADAS view, as well as the blind spot cameras, and reverse camera to display a still image, even while the vehicle is moving, or display no image at all. Also, if this happens while Highway Drive Assist is active, the state of the system is not displayed and an audible chime is played.

I believed my car had a problem with the seals of the windows allowing severe wind noise. After attempted repair the problem persisted and, on closer inspection, it became evident that the driver side door is mis-installed and crooked. Rivian attempted to reprair this and only made it worse. The amount of wind/road noise that is coming in now is as if the windows was open. The door frame vibrates and whistles at speed. The mobile tech doesn't feel this is repairable but Rivian won't take responsibility for it. They have denied my BBB claim and I am pursuing a lemon lawyer.

Rivian alerted me that there was a “service action” related to the hub, and while waiting for that appointment, the hub came loose while driving and began grinding against the brakes and went into full system shutdown. The truck needed to be towed and the hub and brakes needed to be replaced. The truck was undrivae while driving at highway speeds and could have crashed. When questioned, the service center reiterated that this was “not a recall” but simply a head up. The repairs were covered under warranty.

The horn no longer works. Mine and other’s safety are at risk because I have no way to relay hazards while driving.the issue has been ongoing and dealer has not reached back out. The component has not been inspected. No warning lights or messages.
