I have purchased recently an ex demo RX400h with about 6K miles. I immediately identified a vibration which I took to be the rear wheel balance. The garage have changed the wheels and tyres to a different manufactuer as they said it was the wrong manufactuers tyres on it. They have balanced the wheels but it still gives an unpleasant vibration. The garage now say they will not contact Lexus on the matter as 2 other demos have the same characteristics. Any suggestions?
