NHTSA Complaint #11656272 — 2019 NISSAN KICKS

I have had a dispute with the Greensboro Nissan. . I had an issue with all of my lights coming on on my dashboard, my car started vibrating and cut off while I was in traffic. I Immediately scheduled a service visit for 5/9 I had the diagnostics checked on my vehicle and was informed it was my mass air flow filter & sensor. I planned to come back the next week to get the repair done and was told that they tried a temporary reset since I didn't plan to do the service that day but it may not last long. I was about 2 miles away from the dealership when my car did the same thing and cut off again. I called to take my car back and they did go out of their way to help me get a rental car while my car was being repaired. I was told that diagnostics were ran again and it was giving the same code for the sensor & filter. I picked up my car 5/13 and was told that the repairs were done. I was told that my car was put on diagnostics again and checked but no other codes came up. On 5/21 my car dashboard lit up and cut off again so I scheduled an appointment for 5/22. This is where it gets interesting, because I was told that My car was put on diagnostics again and the same readings came up again but it was the throttle body. However, this time I was told that the tech that performed the check on my vehicle stated that the reading about the throttle body was there before but he didn't mention it because it was a more expensive repair (so to speak). I asked why wasn't it listed on my paperwork as far as the diagnosis when I came the last time and no other explanation was given. It even stated on my receipt that the MAF sen/circuit were running properly and that no trash was found in them at that time. Now I am stuck worrying if my vehicle is going to stop on me again. I researched it on the internet and apparently I am not the only person this has happened to. Is there a way that I can I get help to resolve this issue and have it investigated? Thank you.
