2018 Nissan Murano cruise control problems

Tl* the contact owns a 2018 nissan murano. While driving various speeds, the cruise control disengaged without warning. The contact stated that the cruise control feature of the vehicle was controlled by a collision control system, which malfunctioned while on an incline and while driving various speeds on a bridge. Each time the failure occurred, the vehicle decelerated without any warning or brake lights illuminated. The dealer was not made aware of the failure.

While driving my 2018 nissan murano, all of a sudden my vehicle began to de-accelerate and lost it's ability to accelerate. I immediately attempted to pull onto the median of the highway and realized that my brakes were malfunctunctioning, but by then my vehicle was at such a low speed that the brakes were able to stop my vehicle when the peddle was depressed all the way to the floorboard. Three warning lights were indicated on my warning screen and my RPM indicator was bouncing up and down.
