we at Lexus care about your overall ownership experience. To assure you that we stand behind our product, we are
offering this CSP for this specific condition.
Called the dealership to set up the appt for the Customer Support program letter I got in the mail. I was told there IS NOT a program on my car and I must have gotten the letter in error. Nevermind it has my VIN # on the letter. She said she check for the program on both my cars (06 GS300 and 07 GS350) and there was none. After going back and forth (this is a complaint I have had for some time, which she saw in my records). She placed me on hold to talk to a service provider, then she told me it was just an appt to come in run a diagnosis on the car???? and the fee would be waived.
I decided to give up talking to her and will talk to the service provider tomorrow when I drop my car off. I am also getting a engine oil low message after having the oil changed only 3000 miles ago (another on going complaint)
if she keeps saying that its an "error", id call lexus corpo and have them verify the letter.

How can you find out if your model is affected? And does the rough idle go away or is it a constant rough idle at stops?
I have been having this issue for years. in 2011, they said it was carbon build up in the fuel injection system that was causing the misfire. I had the fuel injection cleaned, but that did not solve the issue. In 2010, they could not duplicate the issue and stated the car was working as designed.
I usually have the misfire when I come off the highway and stop at a light. The engine stutters and feels like it will shut off, after a few seconds, it goes away. Until the next time..... This also happens when I an just sittng in the car, in park.
Thanks for posting the letter. It looks more like Lexus is extending the engine warranty for another 3 years [unlimited mileage] on top of the 6 year power train warranty to cover this rough idle issue.
I personally haven't experienced this issue, but it's good to know Lexus will step up and fix it for another couple years.
