Leonardo Never Nissan 
2013 Nissan Sentra Sedan SR 4dr Sedan (1.8L 4cyl CVT)
Never a Nissan on my life!
 Transmission got broken when my wife traveling to CA, the dealer on Tracy CA, and only one on the area spend weeks to get it fix. After several months we sent the car tot Tulsa OK to be used by my son at college; the car presented some noise getting worse with time. When taking the car to the leader it was determine by the dealer that it was a result of an error performed during the transmission replacement. The technician left a bolt loose or too tight stripping the bolt and causing a possible safety issue. The dealer kept the car for 10 days on a "waiting for parts status" after these ten days and calling and pushing the dealer for the repair od the vehicle. We were notified that the dealer at CA denied our claim and there is nothing they can do. I contacted Nissan directly and tried to get them to honor the extended warranty and their response was. Nothing that they can do, that the dealers are "independent" of Nissan and I should deal directly with the dealer at Tracy CA.  Nissan is not being accountable for the bad performance or training of their technician or services provided by their dealers. Sure they will push you to utilize their services as for warranty requirements, but they are not willing to cover for their mistakes. Now I was required to sign to take my vehicle back and release them for any responsibility because now it is a safety issue.  If you are expecting that you will have a NATIONAL service form Nissan you are wrong and you are left alone to be the victim of a poor service and quality of their products. Save the time and lets switch TOYOTA, at least they are honoring every service and job performed on my Toyota Tundra; what a difference on service and quality !  Never NISSAN !
