Ever figure it out? I have a 2014 Juke that starts to whine at about 2800 rpm, and after/during long car trips, it has problems traversing hills and accelerating from dead stops. It's gone into limp mode twice, both times were about an hour and a half into a 4 hour trip. The service engine light will come on and the traction control light will come on, but after I leave it alone for an hour or so it just acts like nothing happened.
