2025 NISSAN SENTRA Engine Problems

I am submitting a vehicle defect complaint pursuant to 49 U.S.C. Chapter 301 regarding a potential safety related defect involving engine, electrical, and powertrain systems. The vehicle experienced early engine and electrical malfunction at relatively low mileage, requiring replacement of the engine wiring harness and removal and reinstallation of the engine and transaxle assembly. These are major powertrain and electrical repairs not reasonably expected on a nearly new vehicle and raise concerns regarding vehicle reliability and safe operation. The vehicle displayed a Malfunction Indicator Light warning indicating an engine and emissions system malfunction, with warnings that continued operation could cause additional damage. Such warnings and failures create a risk of reduced power, drivability issues, or further system failure while operating the vehicle. Insurance repair documentation reflects the selection of a recycled LKQ drivetrain related component, including a recycled engine, transaxle, or CVT related component, which raises additional concerns about durability...

The contact owns a 2025 Nissan Sentra. The contact stated that while driving at an undisclosed speed, the “Shift to Park” message displayed, and the vehicle lost motive power. The check engine warning light was illuminated. The contact turned on the hazard lights and waited for the vehicle to cool down before restarting.

The vehicle was not repaired. The contact later discovered that the vehicle was previously owned by Enterprise Rent-A-Car and was involved in a crash. The manufacturer was made aware of the failure, and a case was filed. The...

I purchased a certified pre-owned 2025 Nissan Sentra SV from a local dealership here in Georgia for my wife. It had 1500miles on it at time of purchase. We have had it less than a month and observed engine shutdown, and totaled power loss about five times in traffic. This is a safety concern because it is random without prior warning. The engine shuts down, dash screen goes black, and you are unable to warn others with hazard lights due to total loss of power. Recently, the vehicle did give dash codes alluding to the problems described, however the dealership was unable to identify the cause or duplicate the problem. When the incident occurred again, I towed it to the dealership, and they still have not gotten answers as to why the car stalls without warning. Unable to move the gear shift to neutral so that the vehicle can be...
