I have not seen anything regarding this subject. I just got back from a cross country trip where my Insight was jam packed. We left Yellowstone and were heading to the Grand Canyon when the charge indicator would only indicate 5 bars, even when my foot was on the brake. Same thing with the assist indicator, I was only getting partial assist. Even so, the battery was nearly fully charged when it suddenly went to one bar and the IMA and "check engine" lights came on. Thank goodness I was only about 45 miles from a dealer in Kingman, AZ. The problem was that I had the vents inside the car blocked not allowing the air to circulate and cool the IMA batteriers, so they basically overheated and shut down. There is a vent behind the passenger seat, and one on each side of the cargo bin in the rear. DO NOT block those vents when you pack for a trip or you could cause yourselves a big problem :!: :!: :!: The dealer reset the engine warning lights and charged? the batteriers, and charged me $91. Said because I caused the problem it wasn't covered under the warranty. Everything seems to be working fine now. This subject should be much more prominently displayed :!: I have looked and can't find mention of it anywhere.
