Other Fuel System Hoses Lines/piping, And Fittings problems of the 2013 Hyundai Santa Fe

Trying to pull over at parking lot, the engine was suddenly stopped at about 16:00 on the day of may 15, 2016. Tried several times for restart, but in vain. Battery status was good. Called service dealer and they couldn¡¯t get the cause of the malfunction, they sent my car to the upper leveled service workshop. The shop manager said his hands are tied in this case and explained accumulated metal(aluminum) particles blocked the fuel flows of high pressure pump of the fuel supply system. And the car needs replacement of whole fuel supply system from fuel tank to fuel pressure pump. During the 4 years of occupation of the car, I have driven the car in very normal and regular manner. At every 7~8,000 km, fuel filter was replaced with new one. The accumulation of the metal(alumnum) particles seemed come from the defective part during the manufacturing by factory. If this occurred during the road operation, sudden engine stop may cause a crash, injuries, deaths. Now the driver¡¯s is in a serious mental condition of deep concern on the possibly fatal crash, even not occurred. The real problem is they don¡¯t know the exact reason of the metal particles accumulation in the fuel supply system. Because they don¡¯t know the real cause and the warrantee period completed, the car owner is responsible for the repair cost, maker is insisting.
