NHTSA Complaint #11468888 — 2016 KIA SOUL

I was heading home on the highway when I noticed the car was having trouble accelerating.  I was taking the exit to my house when I heard the knocking in the engine start.  I was half a mile from my house so I continued slowly as the acceleration issues continued. As I was getting closer to my house the oil light came on.  I parked the car in the driveway and turned it off immediately. A cursory inspection indicates that the engine has suffered catastrophic damage. There is high end a “tapping” sound coming from the top side, even while briefly idling the engine, indicating damage in the area of lifter/s and/or camshaft lobe/s. Inspection of the engine oil presents metallic particles. Finally, we observed that an uncharacteristic and excessive pressure is coming from the crankcase when the oil filler cap is removed while the engine is idling. This is consistent with the GDI engine failure mode - lack of lubrication between piston rings and cylinder walls due to fuel thinned oil caused by high-pressure fuel pump Fortunately, since I exited the highway and the failure occurred close to home, the dangerous stall condition that is a typical failure mode of the GDI engine did not occur in this particular instance.  Nevertheless, severe damage to the motor has been observed.  The fact that the engine began “knocking” prior to the low oil indicator lamp illuminating would indicate that the engine was damaged due to the thin oil/fuel mixture rather than the engine being completely deficient in lubricating engine oil. Internet research has brought to our attention the issues and the precedent-setting class action lawsuits, that Kia Inc. has been forced to contend with due to the inherent design problems of the Theta II, GDI 1.6L, and 2.0L engines - direct injection (DI) system and high-pressure fuel pump issues causing the engine failure through piston ring “blowby” and subsequent thinning of the engine oil. I contacted KIA and I still have the Soul in my possession.
