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.

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.

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.

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.
