2018 Murano Platinum - less than a month after purchase we noticed the steering was difficult. I mean like an old truck with no power steering. It got to the point where I could barely make normal turns. While I'm not Dwayne "The Rock" Johnson, I am strong enough to steer most vehicles. My wife almost could not drive it. Cut to the chase, the dealership (thankfully very good/responsive) replaced the steering column and the problem went away, until today. Twice, while in traffic, the steering locked up. Once I thought we were heading right for the curb. The problem cleared up after stepping on the bakes. Fortunately we were at low speed. Very scary and dangerous. Is anyone else having this problem??
