NHTSA Complaint #11714143 — 2025 NISSAN SENTRA

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 and safety when installed in a nearly new vehicle. Early powertrain and electrical failures involving engine management and emissions systems may implicate compliance with federal motor vehicle safety standards and warrant review under NHTSA defect monitoring authority. I am requesting that NHTSA log, track, and evaluate this complaint for defect trend analysis, potential noncompliance, or further investigation under 49 U.S.C. Chapter 301 to determine whether similar failures are occurring in other vehicles of the same make and model.
