Nissan security light on 2

That solid red light on my Nissan's dash with the car icon is the security system indicator, meaning the factory alarm is armed and the ignition is locked. It's normal to see it flash when you lock the doors, but if it stays on solid while driving, there's likely a key fob or transponder issue that prevents the car from starting. A quick check of the battery in your fob or re-syncing it usually fixes it.
