My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
Check for any after market installed remote starts or alarm systems as one of these components can short out/fail electronically and cause this issue here.
If these are not installed or are found to be o.k. this sounds like a possible fault with the switch itself on start up shorting out needing replaced or possibly an issue with a body control module needing replaced.I would have the fault codes checked to see what codes are set then diagnosed to locate and repair the fault here.
Thanks Pete
