Business ProfileforGreensboro Nissan

I had no issues with Greensboro Nissan until recently. 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 at Greensboro Nissan. I had the diagnostics checked on my vehicle and was informed it was my mass air flow **************** I was told that they tried a temporary reset but it may not last long. I was about 2 miles away from the dealership when my car did the same thing & cut off again so I took it back. I was told that diagnostics were ran again and it was giving the same code for the **************** 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. 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. I asked why wasn't it listed on my paperwork the first time but no explanation was given. It even stated on my receipt that the *** sen/circuit were running properly and that no trash was found in them at that time. The ***************** made the offer that I can pay $600 for a different part and he is willing to zero out the labor. Why should I have to pay full price for another part when they led me to believe that my vehicle was fixed the first time and it wasn't. How many other parts will they charge me to experiment with instead of correctly diagnosing and fixing the problem.If this is how Nissan gains a profit in maintenance by misleading customers and charging for repairs that are not the problem. I think the consumers need to be aware.Something needs to be done and I want my vehicle repaired correctly.
