I have an '06 with 100K miles. I love it and have had no issues with our heavy rains in Florida. Drove to Ohio for Christmas and had snow/ice from Virginia to Ohio - first time driving it in nasty winter weather. The last leg was over hilly, rural Ohio with several inches of snow/ice - I would not have tried it in our Camry or old RAV4. Traction control kicked in a few times but had no problems at all. Found out next morning snow emergency was in effect and dozens of accidents in the area.
I love the RX400h but extra expenses that I have found out hard way. AC went out (and you need AC in Florida) - expensive on any car but with the hybrid a $1500 repair was over $3500 (and I shopped around)! At 90K recommends timing belt change - about $650 with water pump on most cars is $1200+ repair on 400h. Neither repair is unusual for any high-milage car but expenses are 2x+ for the hybrid. To their credit, the dealer service is excellent and costs were LOWER than local mechanics estimates.
