I have RX400h SE 6 months old, did not use for three weeks due to hols would not start, flat battery. Was told by dealer service deparment that this is normal. Find this hard to believe as over 75% of the time ( gestimate ) it runs on petrol surly, a 40K car would have a battery that would last longer than three weeks? I have no great kowledge of the electrics/mechanics re above just find hard to believe,
