The service manger told me that if the tech finds a problem with your car that you were unaware of and is not a safety issue, they won't fix it or even tell you about it. How dishonest is that to withhold information about a problem with your vehicle because Lexus doesn't want to pay for the warranty repair if they don't have to. I have lost all faith in this dealership. I can't trust them to fix my car or tell me what is wrong with it after being told this information.
