I have had nothing but bad problems with my 2008 Altima that was purchased at Texas Nissan of Grapevine. It has been in their shop off and on for the 2+ yrs that I have had it. I took it in today due to heavy exhaust smoke and Scott (service guy) immediately told me "this is normal smoke". I explained the situations of the smoke further, and that other people had noticed it too. When he pulled my car up in the computer and noticed it had not been to the dealership in 20, 000 miles (because I refuse to give them more of my money and take it locally to be serviced) he started telling me there was an engine problem and I would have to show me receipts for all of my services at other places. This is a lie as the car is still under warranty and should be fixed. I also find it ironic that there was no problem according to him, but when he noticed I had not brought it in for any routine service to them it all of a sudden had an engine problem I would have to pay for. POOR CUSTOMER SERVICE at all times, and everyone there is crooked. I would not buy another Nissan ever due to all the probelms I have had here.
