2013 Nissan Sentra beware
 Bought a certified pre owned 2013 Nissan in oct 2016 , within a month check engine light came on , it has been back to the dealer every month since then , my car has no power going up a hill , when at a red light the vibration is beyond anything I have ever experience before , and the noise coming from the engine , and every time I take it in I am told this is the way the car rides , very dissaponted in Nissan for not fixing the issue , I have read hundreds of reviews and everything I am experiencing leads to the transmission slipping . I think I'm going to have to get a lawyer
