The quality of Nissan vehicles seems to be deteriorating. I own a 2017 Nissan Pathfinder, which I purchased in 2017. My vehicle, with approximately 72,000 miles, was recently diagnosed with a serious engine problem by the service department at Gurley Leep Nissan. We ended up paying around $16,000 to replace the engine. While I understand that the warranty has expired, a critical failure on a vehicle that is only 7 years old with relatively low mileage is both unexpected and unacceptable. I bought the Nissan Pathfinder based on its reputation for quality and reliability, and it is deeply disappointing to face such a significant issue at this stage.
