Didn't want to start a new thread so using this one. I got a letter from Toyota on Friday, It reads -
Campaign number BGG55
Toyota is contacting you to inform of a Safety Related Recall Campaign involving your Aurion. YOur vehicle is equipped with a driver's side Power Window Mater(I think they mean Master) Switch containing sliding electrical contact modules. These modules are lubricated with a sprayed-on grease that may have been applied inconsistently during the manufacturing process, not providing sufficient coverage. During normal operation, debris caused by wear from the electrical contact points can accumulate between the terminals where the grease was insufficiently applied, and a short circuit could form between the contact points by the debris. If a short circuit occurs, the switch assembly may overheat and melt. A melting switch may produce smoke and, potentially, lead to fire.
Then is says the usual, to make an appointment to have the switch inspected for more grease or to have the circuit board replaced if need.
Thought I'd share, couldn't find a previous thread on the subject.
