Recently reported VEHICLE SPEED CONTROL problems on 2014 Infiniti Q50

First instance: while driving on the highway going 60mph my car powered down, preventing me from controlling the car. the gauges and lights inside the car went dark and mph went to 0. i lost electrical power and after 1 minute the car is back to normal. second instance: as i was pulling into a driveway and went over a bump the car lost power and powered down, i naturally pressed the gas before i understood what was wrong, the car powers back up as i'm pressing the gas and caused me to almost hit another car.

My power steering belt snapped off. prior to that, my brake pedal was loose enough to move it up and down roughly a 1/4 of an inch with my foot. the only way to engage the cruise control was to hold the brake pedal up with my foot, then in order to keep the cruise control engaged was to keep holding the brake pedal up with my foot because it would sense that the driver slightly tapped the brake pedal to disengage it if i stopped holding it up manually. i had to have the brake pedal bolt tightened. it has happened again and i can't reach the bolt, so i have to pay to have it fixed again along with the other issues. the other issue is my a/c blend door is not operating, which is causing the two driver side a/c vents to blow warm air out of them while ever other vent blows ice cold . not fun in these incredibly hot and humid georgia summers.

I am experiencing software related issues that have become increasingly dangerous. in sum, the infiniti software shuts down or locks up forcing me to become an it technician while driving. when the software shuts down, i lose the speedometer, tachometer, climate control and audio control. here's an overview of my experiences for the past 3 years: randomly, the software will shut down leaving me without my instrument panel (speedometer, tachometer), climate control and audio control. randomly, the software will lock up leaving me without climate control or audio control and the only resolution is to pull over, shut down and restart the car randomly, climate controls are set to 60 degrees w/ ac yet hot air is blowing out of the vents. most recently, the onboard clock that displays the date and time will reset to 01-01-2012 and the clock will start at 6:00 am. the only resolution is to reset the date and time. this seems to occur every 3 or 4 weeks. when i call the service department i'm asked to bring in the vehicle only to be told that all updates have been applied and the issues cannot be duplicated. i have taken and posted several youtube videos showing the problems-which i'll admit is very dangerous to do while driving. in fact, i firmly believe that when these software issues occur, i am forced to play the role of an it technician and troubleshoot the issues while driving which is incredibly dangerous. these issues occur randomly while driving. this is a lease vehicle and i plan to return early as the continued issues put me and my family in danger.

This vehicle has an electronic braking system that has made this car handle erratically and extremely unsafe in traffic situations. while traveling at speed if traffic in front of you happens to brake or swerve in front of you this car will brake uncontrollably without notice making it nearly impossible to avoid a collision or change lanes to maneuver around on obstacle or car. myself and my wife are very scared to drive this car and in freeway traffic you cannot safely change lanes. we feel it is only a matter of time before this poorly designed system which cannot be disabled will result in collisions or death. this has happened more than a dozen times since purchase in april 2014. we no longer feel safe driving this car.
