Hello all,
By way of introduction my name is David and like the rest of you, I have an RX450h with the exact same problem. I have been in touch with Lexus on a number of occasions and they have been less than helpful. My car has been serviced by Lexus and according to the techs at Lexus, the EV mode is operating properly but, and I quote from the head foreman at Lexus, that the EV mode is "utterly worthless".
When I bought my Lexus, from Lexus I was told how great a feature the EV mode is, since I live in Los Angeles with such bad traffic I could save a fortune on gas by simply switching it to EV mode. I have yet to find that to be the case. Like the rest of you, the circumstances by which the EV mode needs to be in to operate at all, render it to be a useless feature. To date, I have never been able to get it t work for more than 10-15 seconds and have made a series of videos to show as such. These videos can be found on Youtube.
As per my second call with Gina at Lexus yesterday, the EV mode is not for sitting in traffic but for "parking".
I don't know about the rest of you but when I was buying my car, the EV mode was the feature that sold me on the car and the reason I bought the car.
I have since retained a lawyer to begin the steps for a class action lawsuit against Lexus and would love to have anyone else that feels like they were deceived by Lexus to join the lawsuit.
You can reach me via email at david@solidmusic.net and I can fill you in on the steps that need to be taken to further the progress of our complaints and the suit against Lexus.
Thank you for your time and I look forward to speaking with some of you, if not all of you.
Regards,
David
