It would not cost you anything but your time your vehicle is under warranty your battery is under warranty at this time. Take to dealer let them fix check it out or fix it. This way there is a record of problem even if they don't find anything wrong. If the same problem would occur later on they have a record.All of you have been very helpful, and I appreciate the feedback! Rather than giving this a go on my own, I am simply going to take the vehicle into the dealer on Friday morning for a look. It hasn't even been a month that I've had the Ridgeline yet, so I've already made it clear with the dealer that I'm not shelling out any dough for service.
