Though the publication doesn’t cite specific mechanical issues with the full-size Nissan Titan, Consumer Reports predicts its reliability to be way below average with a score of 1 out of 5. CR provides little in the way of specifics here, however, and the Titan otherwise gets decent marks for performance. The only durability data presented is for the 2017 model, with its lowest score being for engine cooling, climate control, and body integrity.  The Titan is not rated as part of JD Power’s 2019 Dependability Study.
