A documented recall, NHTSA 26V143000, affects 2020-2026 Rolls-Royce Cullinan models including Series II variants, because the rear seat belt fixing bolts may not have been properly torqued at the factory. Over time these bolts can loosen, which may damage the left or right rear seat belt webbing or allow the rear backrest to move forward under luggage-compartment pressure. A damaged belt or unsecured seat back can fail to restrain occupants properly, increasing injury risk in a crash. This is a recall remedy, so inspection, belt re-torquing, and any needed replacement are typically performed free of charge by an authorized dealer.
