After extensive complaining
After extensive complaining and calling various people at Lexus 800 number then being forwarded to Lexus corporate - of which I am still waiting call backs, that I will never get...... Lexus basically told me to get lost / they would not do anything beyond covering parts.
Being in was not going to put 5-7K in my car I asked if they would do the top engine cleaning described in the other posts.... after a week they agreed. (Service Advisor told me they were more then willing to do this as it was cheaper / only cost them $200ish dollars - retail $600ish)
My car now runs better then it ever has! Granted, I know it's just a band-aid and the issue will occur again in most likely 4-6 years.
I am still searching for a class action attorney who will handle car cases.... because a bandaid is not a proper fix in my opinion! I will keep you and everyone posted.
