Yes, The local lexus dealer was actually involved with the inquiry at my toyota dealer. The toyota service writer called the lexus dealer to ask about the procedure and the lexus service writer said “we only look at the AHC if there is a problem”... I was like, “you’ve got to be f***ing kidding me”!?That's sad to hear
Have you tried Lexus dealers? They may know more given that most LXs have AHCs.
But I wouldn't be surprised if Lexus charges even more than Toyotas.
Here are the two quoted responses fron the toyota service Dept.
Hey Corey I just called over to the Lexus dealer in Portland pretending to be a new owner of this vehicle. They told me that it's a big job and that they don't do many of them. They don't recommend having the service done unless there is a known problem and you would get a warning light if there was an issue. I asked them if they have a price estimate on a job like that and he said that they wouldn't be able to do a price estimate without seeing it first and diagnosing it as having that problem. That being said I unfortunately don't have a price estimate or anything like that for you to have that done. and they really enforced that if your not having a problem with it to not mess with it. Sorry I couldn't give you an estimate on that.
