Dealer is better

I will go to a dealer, and get a peace of mind if there is anything wrong other than the battery, which should be covered by the 3-year warranty.

I got a good experience with a Honda dealer on the battery. The dealer did charge me more than $40 for the battery than other stores (WalMart & AutoZone). After two years during a oil change service, the same dealer checked the battery, found that the battery was weaker, and replaced it with a new one.
