Over past 25 years of Toyota owner ship the dealer to dealer experience is not very consistent. All of them have notified me of any recall the moment my vehicle was scheduled for an appointment or after it hit the shop. None have ever notified me about a TSB which according to one dealer is a dealer only document explaining a given set of issue and fixes to said issue along with trouble shooting procedures it is not for customer consumption. I have had 3 different experiences with TSB that I brought to dealers attention. First was pretty easy I told the I was having problem X and Toyota had TSB about this issue. That dealer just applied the TSB and charged me labor, my parents Camry. The second was we have to first do a diagnosis and if we can repeat your issue we will follow the procedure in TSB this is were I got the lecture about TSB not being for customer consumption. This one I was charged for diag and fix (it was Trans TSB for 2016 LC). The last one was this AC TSB that I was sent in mail by Toyota and I provided info to my dealer about it. They did quick check of vehicle and said my was not displaying the symptoms and sent me home. I do not have anything wrong with my AC so I agreed. They did this as add on with scheduled oil change no cost. Same dealers as Trans different service tech. I wonder how Lexus boys get treated on these things.
