Some are saying Frontier needs an upgrade. But they are selling pretty well. My understanding that part of why they still sell well is the lower cost due to not much upgrades in regards to techie stuff. One, that helps keep the cost down, and two, a lot of light truck buyers don't want a lot of bells and whistles, they just want a reliable vehicle to haul stuff around in--new chair, maybe some lumber from the home improvement store. They don't need it to have DVD players and all that stuff.
I'm happy with it, and it has been a reliable vehicle for me. I also drive a 2015 Murano. Love the looks, has been reliable so far. Don't like the tech on it/console layout. Horrible.
My newest neighbor that recently moved in had 2 Frontiers. One of them has to be 20 years old. He used to work at Nissan.
