2021 Nissan Murano SUV FWD

A specific cruise control feature of the 2021 Nissan Murano, in my opinion, is dangerous to operate and may or may have already caused a serious injury/accident. I have brought this concern to the people at the Dealership in Tucson, AZ on several occasions. I have also contact the Nissan North America Consumer Affairs Office in Franklin, TN. Both of these parties have told me the cruise control system is working properly. So what is my concern? The last four cars that I have owned had cruise control systems. Two of the cars were Nissan Muranos. A 2010 Nissan Murano and a 2014 Nissan Murano Platinum. All four the cars' cruise control systems operated the same. Unfortunately, the 2021 Nissan Murano's cruise control does not operate the same as my last four cars, The 2021 Murano has one feature that is very dangerous and needs looking into. Example of the four previous cars: Let's say you set the cruise control at 40mph and decide to increase to 50mph by pressing and holding the RESUME/+ lever. All of the other cars that I owned would allow me to do this and when the speed odometer reached 50mph I would release the RESUME/+ lever and the cruise speed would be 50mph.The 2021 Nissan Murano Platinum does not do this. Example of 2021 Murano: Let's say I set the cruise control speed at 40mph by pressing and holding the RESUME/+ lever to increase to 50mph and I release it when my speed odometer reached 50mph. The 2021 Murano does not stop at 50mph it would go to approximately 80mph unless the driver steps on the brake. FYI, I did drive two other 2021 Nissan loaners neither of which were Muranos, Both of those cars' cruise control operated as my previous four cars' cruise control system. The car's manual and videos' documents that the cruise control should operate differently.

As I was driving up a parking garage ramp, about 1/2 way up the ramp, the vehicle slammed on the breaks like a front end collision was imminent. There were no cars in front of me, and I wasn't close to any required turns in the parking garage. If someone was driving too close, they would have rear-ended my vehicle. The vehicle simply had no reason to stop on its own.
