ENGINEThe engine failed due to coolant infiltration, which caused catastrophic damage and required a full engine replacement. The failed engine remains at Conyers Nissan and is available for inspection upon request. When the vehicle finally started, thick white smoke poured from the exhaust while it was in my garage with the garage door raised. I immediately removed my child from the vehicle and moved it outside to avoid potential fire or toxic fume exposure. The sudden failure created a serious safety risk to both myself and my child. . After failed multiple phone check-ins then finally going to Conyers Nissan, the shop foreman confirmed the problem on October 13, 2025, and determined that the engine must be replaced. To my knowledge, the vehicle has not yet been inspected by Nissan Corporate, insurance representatives, or law enforcement. There were no dashboard warning lamps, error messages, or prior symptoms before the failure. The vehicle had been operating normally until October 9, 2025, when it suddenly became difficult to start and then emitted smoke. All maintenance has been completed according to Nissan guidelines. The incident occurred on October 9, 2025, when the vehicle had 35,855 miles. It has remained at the dealership since that date. Despite the proposed engine replacement and any other associated component, I no longer feel safe operating this vehicle, particularly with my child onboard, due to the severity and suddenness of the failure. I sent an email to Nissan Consumer Affairs (case# 55923865) requesting that Nissan repurchase the vehicle due to this serious safety concern. The dealership stated they cannot give me an inspection report until the repairs are done. However on the status link that is sent via text to check on the vehicle, the inspection shows complete.
