The failure occurred during normal on-road operation at approximately 60 mph in temperate (60F) conditions. The vehicle has no history of off-road use or heavy hauling.  Safety Risk & Critical Failure Mode: The suspension is a safety-critical system essential for vehicle stability, emergency braking, and predictable handling. A loss of hydraulic integrity in this system directly compromises the vehicle’s ability to maintain ride height and damping control.  High-Speed Exposure: The initial failure manifested while traveling at 60 mph. Although a warning lamp was triggered, the vehicle’s functional safety logic failed to initiate a \"limp mode\" or restricted speed state. This allowed the 7,000lb vehicle to continue at highway speeds with a compromised high-pressure hydraulic circuit, posing an unreasonable risk of loss of control.  Lack of System Redundancy: A localized hydraulic leak resulted in a cascading collapse of the entire architecture. Per the 10,662 service estimate, the repair requires replacing the front and rear dampers, hydraulic pump, manifold, and all fluid lines. This suggests a design-level vulnerability where a single-point failure in the hydraulic circuit necessitates a total system overhaul, indicating a lack of modularity or redundancy.  Safety Protocol Gap: After diagnosing the leak, the authorized service center deferred to my personal judgment regarding operational safety. This forced an untrained consumer to make a critical safety determination on a high-pressure system while the vehicle remained capable of full highway speeds.  Technical Confirmation: An authorized Rivian service center confirmed the failure on March 3, 2026, and determined a full system-wide replacement is required. All components are available for inspection.
