i forgot i did this a couple of weeks ago. My dealer brought up to my attention of a TSB for the frame or something like that. some models affected during production where the welds were not perfect and may cause air to seep through. They put a special sealant under one side of my car . any of you guys got a letter for this ? I'm looking at my lexus receipt and it shows only the sealant that was ordered, i don't see a TSB number.



Edit, sorry i think i see it. here is a picture of invoice. it says rear fender arch.

 

Yeah it's for those that especially drive in the snow. Can lead to rust issues.

 

Heard about this too, asked my dealer a couple different times and even checked on lexusdrivers.com. My car isn't showing up as affected. Do you know if they did the work from outside/under the car? or from inside, removing the rear trunk panels?

 

I had mine done, they removed the rear wheels and threaded a rust inhibitor needle sprayer through the crease of the rear fenders.

 

RCF500 beat me to it. mine was affected on one side. very minute he said. he promised nothing can be noticed from looking at it. they used some type of machine to look through the crease.

 

I'm wondering if mine is really not affected or the dealer just doesn't want to mess with it. Then again, I also haven't gotten a letter or anything.

Thanks! so yeah, I'm good then!
