I have a 2011 Honda Pilot with the 3.5 v6, automatic transmission and 126,000 miles. When I turn the key to start sometimes it fires right up other times the starter will spin for 45 seconds before it will start. Once started  it runs smoothly without any missing or hesitation. This issue appeared several months ago and never really bothered me cuz  it would go months without issue. Now it is becoming a daily occurrence. I did take it to the dealership about the issue but they were not able to replicate the issue or find any codes. Any ideas on how to fix as I am concerned it is getting worse and eventually will not start at all. Thanks for your help.
