While being driven, the ecodiesel engine had a faulty ball bearing that malfunctioned inside the engine. This ball bearing then shot through the middle of the engine and out the bottom of the engine. The service technician at our local dealership inspected the engine and compared this to a ‘bullet under too much pressure due to a fault within the engine.’ He then said we ‘were lucky the ball bearing hadn’t shot upwards through the floorboards.’ Not only could we have been at risk, other passing vehicles could have been shot with the ball bearing; this event could have led to wrecks and possible fatalities. The engine was completely destroyed by this defective ball bearing and cannot be rebuilt. No lights or messages appeared after the ball bearing shot through, even though the oil began draining instantly. The truck was pulled over and turned off before all the oil drained to prevent damage to the engine, which was already destroyed without us knowing.
