On January 1, 2025 at about 10:30pm, while driving at about 40 miles per hour the engine made some knocking noises and then suddenly lost power, forcing the car to be pulled over to the side of a dangerous road. When I opened the hood of the car there was a small amount of smoke.  There was no advanced warning that there was a problem with the engine, it just stopped running causing a dangerous situation.  I had the car towed to Infiniti of Massapequa and was told the next day that the car needed a new engine. I was told by the dealer that there was metal in the oil and it appears the main bearing broke. The car is only about 6 years old with approximately 26,200 miles and  has been extremely well maintained with the dealer, including scheduled oil changes with full synthetic oil. I am trying to get Infiniti to cover the full engine replacement cost since the warranty expired about two months ago. However, they still want to charge me $7,560 plus tax. The Infiniti service report is still pending the repair.
