We bought a 2013 Nissan Sentra,on 11/02/2013, because we had so much luck out of our 2001 Altima , the frist week we had it my wife complain that it was trying to die at idle some times , i laugh and it's a new car it don't do that and we switch gas station, then it done it again real bad about two weeks latter .I took it back to the dealer and the upgraded the Ecm , they said that should fix it , a week latter did it again , took it back to the dealer ,they had it for about four days , and said they couldn't get it to do it for them and they check the ECM again . This all is happening before i have even made my first payment , .We mostly notice it dose it when there are a lot of stop lights in a row . This has been the worse experience that we have ever had , it make you gun shy about driven our new car , and since it only dose it when it wants too scares us.We have had it back from the dealer for a week and it hasn't done it yet but we been driven our old car since it's more reliable .
