I have a 2008 HCH-II with approximately 73,500 miles on it. It has been in the high 90's to low 100's here in NC the last week. Every time I drive after the car sits for a few hours or more, it will start a recal, down to 1 or even 0 bars, within the first mile of driving that will last up to 10 miles. Sometimes it will go until it has a full 8 bars of charge, but just as often it will stop 7 or even 6 and then quickly drop to as low as 5. Even if it reads 7 or 8 bars at the end of my trip, it will again do a recal the next time I drive it. I am taking a 5-10 mpg hit on my trips and tank mileage as a result. Should I take it to the dealer and have it checked out? I know the battery packs in the HCH-II are notorious for issues. So far no IMA light or other indications of "official" trouble. Suggestions and advice? Thanks. PS I bought it used in the summer of 2010 with 30,500 miles on it and don't think it has had the major software update from then. Thanks.
