2025 Nissan Sentra Powertrain & Transmission Problems

I purchased this car around January 2025 & around August 2025 I started having battery issues. It’s currently March 2026. I have to keep having the battery jumped at. When he battery wasn’t jumping I had to get it sent to a nissan where they said nothing was wrong with the car so the next day the battery failed again.. and again each day . I have to keep calling AAA to come have the car jumped which I ended up just getting a portable battery jumper which works sometimes but other times I would have to call AAA of course, or if it doesn’t start at all, I will have to get it told to nissan. Certain times the car would start up and then when you pull out the parking space it’ll start shaking and then you’re driving in the car will slowly turn off. You’ll just be sitting there and that’s the main time you’ll have to get it towed to the dealership. Recently it happened on the side of the road from me, leaving the dealership and the police ended up, towing the car because triple AAA didn’t come fast enough which I had to pay 300 something dollars to get it out of the tow yard. System malfunction pops up, the engine light blinking , battery light pops up.

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.

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 pushed out of traffic is another safety concern. This car should be fuel efficient, yet we were refueling every other day. Not safe!!!
