Gas Recirculation Valve (egr Valve) problems of the 2024 Nissan Rogue

Engine / fuel/smog/emissions system (egr cooler) description of the safety hazard - my 2024 Nissan Rogue experienced a sudden and catastrophic failure of the exhaust gas recirculation (egr) cooler assembly. The internal core of the egr cooler cracked, causing engine coolant to leak and completely drain. This defect caused severe engine overheating, a sudden and dangerous loss of motive power while driving the vehicle went into limp mode, and experience engine stalling. The sudden loss of engine power/stalling on the highway created an immediate, high-risk collision hazard. Furthermore, coolant leaking into hot engine components presents a critical thermal/fire risk. The vehicle is currently grounded and entirely undrivable at an authorized Nissan dealership. The dealership confirmed that the vehicle cannot be safely operated. However, Nissan cannot provide a repair timeline because the replacement egr cooler (oem part 14735-6rc0b) is on an indefinite national backorder due to widespread, systemic manufacturing defects across this engine line. Hundreds of other drivers are experiencing this exact same dangerous failure, and a formal safety recall is urgently needed before it causes a fatal accident.

After shopping, I attempted to start my car and received the "engine malfunction reduced power, service now" warning. Thankfully, I was not driving when this happened, as the car had no power to move! it is currently in the dealership, where they state it is an egr valve -- on a vehicle with less than 11,000 miles on it. Had I been on the highway and this happened - no power -- I only hope I could have coasted to the roadside without being hit!.
