Adaptive Cruise Control problems of the 2020 Nissan Rogue

On Saturday [xxx] while driving on [xxx] while in cruise control mode and set approx. 71 mph I know that my right knee made minimal contact with keyfob and the engine seemed to shut down and the vehicle decelerated immediately, I had no desire to brake due to my seeing my speed was near 30 mph. Traffic was not directly behind and all I was trying to locate was the 4 way hazard to engage which having only recently purchasing [xxx] and I had driven maybe 60 miles I located but with seeing a couple of vehicles approaching and being in the #2 lane my steering was stiff with little chance to get over safely to the #1 lane or to the further left hov lane, I reached down w/ right hand and made very minimal contact with ignition/ keyfob area and the vehicle had power and was able to regain speed. I absolutely did not attempt to turn the key that was still fully in place. I can not say that other than making contact with no aggressive action or intent was I to believe the vehicle would again be running as it had prior and I proceeded the remainder of my trip (approx. 15-18 miles) with no further issues and without a clue other than I had been made aware of the recall prior to purchase and told it was not anything to be concerned with that the jackknife keyfob seemed to lock in the open position fine, and to just leave it in that position, which I did not agree with that opinion as I read about this safety issue and have brought up on at least 4 occasions prior to and after the sale. We were actually informed by the finance mgr. Upon signing there were no recalls on this vehicle, which we made him aware of and he commented that it would be nice if somebody would let him know that! and I informed sales person on two separate occasions as well asking that it receive the final Nissan remedy yet never being taken very seriously and now unhappy with this event when I that my knee making such slight contact is disturbing! information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Crash detector light flashes on and off.

Driving down interstate on nice clear day with minimal traffic, cruise control set at 70mph when suddenly the cruise disengages, warning light begins to appear on dash showing 2 cars colliding with audible alarm informing me that the front radar is obstructed. Cruise control will not work and any attempt to use cruise control is met with audible alarm and warning that front radar is obstructed. I stop, check all radar/sensors for debri. . . Everything is fine, no bugs, not debri, no obstruction. I restart engine, same warning appears before I even put transmission in drive. Start driving, same situation, front radar obstructed, cruise not available. After 10 miles or so the flasing light goes off, everything returns to normal, cruise control works properly. Car may experience this oroblem twice in hundred mile trip on perfectly clear day. Other times it may not happen at all on a 100 mile trip. When this does happen in heavy traffic the situation becomes dangerous quickly because the automated braking is disabled and if the radio is on it's easy to not realize the system is off until your speed is reduced significantly. I have had 2 close calls because of this - one with a car in front of me stopping abruptly and the system failed to maintain the selected gap between my vehicle and the vehicle in front of me so I had to veer onto the median to avoid a collision; the second time the cruise abruptly disengaged traffic behind me almost ran into me which caused vehicles behind me to have a close call. So far this problem has always happened on the highway or interstate, never in town. Sometimes when it is raining really hard the same warning light & audible alarm will sound, however cruise control remains operational as does the automatic braking. So it appears to work properly at times.
