FYI, my RX was brought brand new and not lease directly from the Bay Ridge Lexus location. The car is now 25,000 miles.. it was 3000 miles when we first realized the problem and told the dealer. They insisted its the gas that we use and suggested us to change a different brand, even to go to the one that they go and we did. And we have always used 91 gas beacuse think about it, we brought the car so that we can drive it for at least 5yrs and we love the car. Why would we do something stupid to destroy the car? But then, we still have the same problem.. so it's not the gas, it's the engine.. they just don't get it.They don't care, they just give stupid excuses so that you just have to live with what you got.
And we do not start and stop the engine frequently to drive in and out of driveway, I mean who would be so boring and have the time to so such a stupid thing.. what is the point of moving the car and and out of driveway if we are not going someway? In terms of traffic, I believe traffic is a problem in every state. How about CA and texas they have traffic problem worst than NYC. As for step on gas hard enough to break carbon down, I believe we did because we are not a slow driver. On average, we get on highway to work at 60MHP and my husband also initially thought of the possibility of step hard on the gas and he did... but still, same problem.
I guess my problem belong to the 10% of the issues where lexus would ignore and try to get away from it. At this point, I will agree with Lenore, that they are all talk but no action.. What will you do if you buy brand new car with engine problem and when you go back to them, they give you the answer as "sorry, there is nothing we can do because YOUR CAR is built AS IT IS, but it does not mean all of 2004 RX 330 which is the same care as you has the same issue." So, now what!!
