While traveling at highway speeds with my family on our way to a college visit, the vehicle suffered a sudden, catastrophic loss of propulsion due to a complete breach of the automatic transmission oil cooler lines (Part numbers: 3QF317801C and 3QF317820C). The breach caused hot, pressurized transmission fluid to violently spray out of the vehicle, covering the highway and completely coating the vehicle traveling directly behind us, creating an immediate multi-car road hazard. The sudden loss of fluid instantly destroyed the transmission internals, disabling the vehicle on a high-speed highway and requiring us to be towed to a Volkswagen dealership. The certified VW dealership technicians inspected the vehicle and explicitly identified the issue as a factory assembly flaw. They confirmed that these two parallel, closed-loop fluid lines were routed from the factory with zero clearance, causing them to rub together under normal engine vibration until friction wore a hole through both walls. This built-in engineering and routing defect poses a severe safety hazard due to sudden, un-alerted power loss in fast-moving traffic and the spraying of highly flammable fluid onto hot engine components and surrounding vehicles.
