Am I the only one who finds the transmission in the LC500H appalling? In spite of a supposed software upgrade, I have grown to really dislike the car for the jolt the car gives you on mild acceleration in going from 3rd to 4th, 6th to 7th (the worst) and 9th to 10th. I have raised it repeatedly with the dealer over the past 9 months, Lexus UK have only just told me in the nicest possible way to go forth and do one. Along with a number of other build issues, I share earlier views that this is by far the worst quality Lexus I've owned of the 6 I've had in the last 20 years. Also the customer care experience has been a very unpleasant shock.
