Every Nissan gas engine sold in the U.S. since the 2005 model year uses a timing chain, while older Nissans with the 3.0- and 3.3-liter VG V6 engines use a timing belt that needs regular replacement.
No issues. I bought the 5 oil change package for my Titan. The rep addressed my concern about a bolt in the skid plate that the tech stripped out on my very first service.
