I have a 2012 Nissan Juke sl awd. This morning on my way to work all was fine for about the first 5-10 min everything acted normal. All the sudden it stay between 4-6,000 rpms and wouldn’t shift. I know the CVTs don’t shift but that’s how I’m gonna explain it. After I left go off the gas and slowed down it went back to normal. After about another 5 min I started to loose power. Eventually it got to the point where I had to drive about 15-35 mph the rest of the way to work because if I tired to accelerate it would just run the rpms up. It’s also making a really bad whining noise. Any help would greatly be appreciated!
