When is a Tune Up due on newer cars?

I have a 3 year old Honda but it doesn't say when tune up should be performed. Just says to do it when the maintenance minder comes but it hasn't come on even after 70,000 miles!

I don't know if I need a SR22 for both of my vehicles or just one

My license is suspended due to driving without insurance. In order to have it reinstated I need a SR22 & a prepaid 6 month insurance policy. I have two vehicles, a 1999 Honda that I own outright and a newer Jeep that I'm still making payments on. Obviously the cost to insure the older Honda is less. My question is once I have obtained the SR22 policy for the Honda and get my license reinstated, do I have to get a second SR22 prepaid policy for the Jeep? Or can I get a cheaper policy with monthly payments for the second vehicle?

Added (1). Do I need a SR22 for both of my vehicles or just one?

Do you think extended warranty is necessary on new cars?

A relative just bought a $40k Honda SUV and is seriously thinking about getting a 7 year/100,000 miles power-train warranty. Do you think he should since it's just $500? Or is it just flushing money down the drain since if you can't trust a new Honda to go 100k miles who can you trust?
