The cost will vary but I think Lexus will be the most expensive - I would try Warranty Direct and negotiate down from their first quote. I got 12 months interest free installments and £50 off just by ringing then after taking an online quote.

As others have already remarked, while clearly some owners appear to have had this problem, others like myself have been completely unaffected. My RX400H SE is 3 years old, 40k miles and I have left it parked outdoors in winter at airports (covered in snow and freezing conditions - normally for a week) and returned to a serviceable vehicle and left it for 3 weeks in summer at an airport - again with no problems. I'm not saying there is not a problem but I would remark that it doesn't seem to affect every vehicle. MN

Absolutely agree with dncm 1. My Rx400h - SE has just had its 40k service and first MOT - all good and returning similar mpg to previous post. Never had any battery problems - even after 3 weeks parked. Dealer is just sorting a minor paintwork issue on leading edge of bonnet - very minor surface rust in one area of stone chip; dealt with under warranty. Also agree that tyre pressures are critical to getting best mpg (common sense really I suppose !).
