my 08 will be two yrs old in aug, been a great car. 34mpg in town in the summer. had an odd problem last week. the hybird had sat for about 12 days without being driven. so i get in start it up like i always do, runs fine but no radio sound, or display, even the clock does not show. so i take it to the dealer, they decide it needs a radio replacement. so have to wait till the next week for the radio to come in. i continue driving it for the next two days till, on the 3rd day it wont start or even try, the battery is dead, has 7 volts. nothing was left on, key was in the house. i charge it over night at 2 amps. next day it starts runs just fine. but now the radio works and remembers the presets even, did have to reset the clock. so i take it in anyway the tell me they checked everything including the battery, all is fine. im glad it's working again, i just wish they could have found something wrong and fixed it. ill be wondering for a while if it's going to happen again.
