2024 Rivian R1T

On February 15, 2025, Rivian performed Field Service Action FSAM-1507 on my 2024 Rivian R1T at 11,590 miles. Hub-to-knuckle fasteners were found loose in four structural locations. This was identified as a safety-related field service action. A second field service action, FSAM-1678 (front halfshaft NVH washers), was performed November 3–4, 2025. I am reporting both actions to create a federal record of the structural safety deficiencies in this vehicle.

2024 Rivian R1T has a persistent pulling defect and safety hazard. Four repair attempts at Rivian Denver Service Center all failed: 1. Jul 16, 2025 - WO-1452784, 16,117 mi: Alignment performed. Defect continued. 2. Aug 11, 2025 - WO-1530133, 16,936 mi: Same-day return. Second alignment. Defect continued. 3. Nov 3-4, 2025 - WO-1745098, 20,520 mi: Rivian lead technician ride-along confirmed pull in writing: "After 2 alignments, vehicle is still pulling. Confirmed by lead technician." Tire rotation attempted. Defect continued. 4. Dec 22-23, 2025 - WO-1869730, 22,136 mi: Rivian documented "No Problem Found" after 2.5hr alignment + 20-min test drive, then waived $690 in labor. I have video of a Rivian advisor verbally confirming the pull in Nov 2025, directly contradicting this finding. Pulling caused premature wear on all 4 tires by 20,774 mi (Rivian confirmed, WO-1765303). Additional safety defects: - FSAM-1507: Hub-to-knuckle fasteners loose in 4 locations (Feb 2025, 11,590 mi) - FMVSS 108 headlamp federal violation corrected Jul 2025 - FSAM-1678: Front halfshaft washers replaced Nov 2025 - 12V battery failure limited vehicle to 61 MPH while driving (Oct 2024, 8,215 mi) Vehicle returned May 27, 2026 due to unresolved safety defect.Please investigate this defect on 2024 Rivian R1T vehicles.

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.

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 contact owns a 2024 Rivian R1T. The contact stated that while driving at an undisclosed speed with the cruise control activated, the "Drive Fault," message was displayed after which the vehicle lost motive power and the contact became aware that the brakes were not functioning properly, requiring increased effort to bring the vehicle to a complete stop. The contact was able to pull to the shoulder of the roadway to turn off the vehicle. After restarting the vehicle, the vehicle returned to normal functionality. An unknown warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 1,700.
