The lightning bolt designates a problem with the Electronic Throttle Control system. My guess is there one thing causing all the issues.

Per the manual: Electronic Throttle Control (ETC) Light (5.7L Engines Only)

This light informs you of a problem with the
Electronic Throttle Control system. If a problem
is detected the light will come on while the
engine is running. If the light remains lit with
the engine running your vehicle will usually be driveable,
however, see your dealer for service as soon as possible.
If the light is flashing when the engine is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle or engine
stall and your vehicle may require towing. The light will
come on when the ignition is first turned on and remain
on briefly as a bulb check. If the light does not come on
during starting, have the system checked by an authorized
dealer.
