The BMW X3 that I purchased from National Auto War...

The BMW X3 that I purchased from National Auto Warehouse (NAW) had engine clatter at delivery that was dismissed by NAW as typical for direct injection engines...10,000 miles later got a Drivetrain Fault, Check Engine Fault, and finally a Low Oil Pressure Fault in rapid succession. Problems with the timing chain guide is a known issue with X3 engines which often causes damage to the oil pump and resulted in replacement at $13,000 in this case. I believe that this issue was known by NAW at the time of the sale, and if they had informed me, the maintenance could have been done before the the engine was destroyed.
