NHTSA Complaint #11474013 — 2015 NISSAN ALTIMA

My 2015 Nissan Altima, I've had it (7 years), started stopping without warning. Last week, I've had the valve cover replaced, because it was oil coming through one of the chambers of my spark plugs, I got a new battery, & I got the oil changed to make sure that everything was flowing correctly and running clean. Then it happened again. I put my car in park, I turned it off, and started again. There were no warning lights or codes that came across the dashboard. It was more frustrating because there's no warning no preparation it just does it so I did a system diagnostic ( Hitting the push to start button 5 times then hitting the door Button on the inside of the door jam 10 times then hitting the push to start button 3 times and the car will test all of the systems). My car was not running hot, there are no warning lights, you don't know when it's happening it feels like it's pulling or struggling with torque, and then before you know it you've come to a complete stop. It happened in the middle of an intersection. Multiple codes are hiding in the system, with no indications on the dash. The code discovered by my local mechanic was P7F1 (transmission code). This is based Tech Bulletin #NTB15083A. Hundreds of owners of Nissans have indicated the same issues with no resolve from Nissan or their local dealerships This is dangerous
