NHTSA Complaint #11474407 — 2013 NISSAN SENTRA

I bought the car in May 2019. The dealership I bought it from said they worked with a Nissan dealership and replaced the transmission just before I purchased the car. Shortly after I got the car I noticed problems. I had my mechanic tell me it was the transmission slipping. In August I took it back to where I bought it and they sent it back to the Nissan dealership to check. The Nissan dealership said there was nothing wrong with it. They said it showed no codes. It continued to be a problem. I eventually took it to another mechanic and a transmission shop. Both confirmed a transition problem. I then took it to a different Nissan dealership. Lamb Nissan. They looked at it and said the program that will show error codes was not up to date and the original Nissan dealership should have updated and it was not updated. They said there is a problem but the program needed to be updated for them to know more. They updated it and I have been driving it with continued problems. I will be taking it back to Lamb Nissan in a couple weeks to have them check it out again. The problems have been after stopping at a stop sign on an incline, when I accelerate it gives a rurring sound as if it is going fast, but it barely moves. Then it will finally kick in and drive a normal speed. It also jerks. Especially when I take my foot off the brake. I have occasionally smelled a burning smell. Not sure if it is related. Answering the questions: 1) transmission - I can arrange for it to be available for inspection. 2) my safety is in question because I don’t know the exact problem and when/if it will just shut down and possibly cause an accident. 3) the problem has been confirmed by 4 places as described above. 4) it has not been inspected other than above as far as I know. 5) no warning lights have come on.
