Just ordered a new ignition switch after going crazy over this problem, hoping if fixes it. No steering wheel button function, no cruise, usually no horn, airbag light stays on, radio will randomly shut off, but stays on along with the dome light when I turn off the car and remove the key. The issue where the starter wasn't getting steady power only began to occur after weeks of the "christmas tree effect"
