Interesting thread for two reasons to me:
1. My business partner has a 400h like me and his battery went flat after he spent an evening listening to his stereo whilst having a barbecue at a campsite. RAC confirmed that the 400h is "well known for having an undersized battery"
2. Having been duly warned, I parked my 400h in my garage leaving good access to the engine compartment when I went away for three weeks. Yup, it was as flat as a pancake when I got back. AA started it for me and I took it for a 10 mile fast drive. No further problems, although having to reprogram my driving position was annoying, and it still doesn't feel quite right....!
Lexus, we need more POWER!
