Have a '99 Tahoe bought about a year ago. Just recently when driving the dash board "security" light comes on while driving. Stays on until vehicle is shut off and restarted. May not come on again until another shut down and start sequence. Normally it came on only during start up and then went off. No other issues, Tahoe runs and drives great. Is it a "sticking" relay or ??? Is it an issue I need be concerned with as in take it to the dealer? Bear in mind, I am "old school" and not very up on the newer computer/electronics in todays vehicles.
