Manufacturing Engine damage/failure. Synthetic oil was used at all oil changes every 5K miles. However, after only 3K miles after last oil change the oil level was low and dirty. Engine light started flashing and failed to accelerate. Engine also started making a knocking noise.
Engine damage from connecting rod bearing wear. The dealer inspected the vehicle. The dealer confirmed that the damage was caused by a connecting rod bearing. The engine had to be replaced. I was told by the dealer that the VIN did not fall within the recall range. Therefore, I had to pay for the engine replacement myself. The engine damage was the same as the NHTSA ID Number: 23V751000 recall.
