Typically a powertrain-only warranty. I saw a message for this at a local Honda dealer, and their terms are online.

Question: Do I have to bring my car back to your dealership when I have a claim?
Answer: Absolutely not. Our Lifetime Limited Power Train Warranty can be used at any licensed repair shop in all 50 U.S. states and Canada. So if you move, if you're on vacation, or traveling, the warranty goes with you!
Question: What are my responsibilities for maintaining my vehicle?
Answer: Easy. Just follow the manufacturer's standard maintenance guide in the owner's manual. This will help protect your factory warranty, as well as your Lifetime Warranty when you have a claim.
Question: Do I have to bring my vehicle back to your dealership for the required maintenance?
Answer: Absolutely not. If you change your own oil, simply keep the receipts for the oil and filter. However, our dealership will electronically maintain all of your maintenance records for submission when you have a Lifetime Warranty Claim.
Question: Who stands behind the Lifetime Warranty?
Answer: The warranty is backed by PSC AutoShield
I looked up what the last part means. Apparently this dealer is part of the PSC Automotive Group, which is 4 Honda dealerships - 2 in California, one in North Carolina, and one in South Carolina. I guess it's provided by the parent dealership group.
