2025 Nissan Murano Powertrain & Transmission Problems

New leased 2025 Nissan Murano vehicle 7,386 miles with recent software upgrade by Nissan dealer, Keyport, New Jersey. As I accelerated from a complete stop, the vehicle experienced an unintended increased excessive speed acceleration and when I applied the brakes to slow the vehicle, the acceleration wouldn't stop knocking me back into my headrest hurting my neck and right ankle. I had to shut off the vehicle to stop it. I then proceeded to attempt restarting to exit the roadway safely and it failed to start keeping in the lane of traffic. A message displayed to update the vehicle software which I did immediately and was unable to restart during vehicle requested update. I put on my hazard lights remaining in the vehicle as snow banks covered each side of the road and it wasn't safe to exit my vehicle with traffic and ice conditions. I was put into a situation where I could not exit the roadway and vehicles were approaching my rear as I was in a single lane roadway with traffic had going around me when safe to pass. After the upgrade I attempted to restart the vehicle and it would not until I opened the door and reapplied the brake pedal realizing that moment I injured my ankle pressing on the brakes so hard to stop my speeding vehicle. It did finally start after the 5th attempt afyer the software upgrade. After this event upon starting the vehicle I drove it off the roadway and the seats began to heat up hotter than tolerable and I could smell what seemed like burning plastic with the steering wheel heating up too hot to touch. I called Nissan and spoke with Angel in her servixe department to find out if there was any recalls or other vehicles with this issue and she didn't know. They confirmed they'll be be accepting my vehicle for service tomorrow morning Jan 30, 26' at 830 where I'll have Nissan roadside service take the vehicle into the dealership.

While accelerating there's a delay when pressing the gas pedal and then a surge in power with understeer causing dangerous lurching forward. Dangerous to merge into traffic and very unpredictable.

[XXX] at 1378 miles received a malfunction warning light for lane departure. [XXX] at 1875 miles pulling out from my home to Railroad Street the engine started sounding really loud like a motorcycle engine and started to decelerate which could have caused an accident. Video was taken, vehicle was taken to Matt Bowers Nissan 7/11/25 and states issue could not be duplicated and that the engine noise is normal. Engine sounds really loud each time the vehicle is started and again was told by Service Technician Foreman Ken that he has seen similar vehicles with the same problem, and this is normal and preceded to tell me about other noises that I will here that is also normal. Here a sound like valves is tapping. New vehicle should be quiet, and this one is very noisy. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
