I got a recall notice last year that basically said this is a heads up. Just got the second notice last month and they now have a fix and parts available to correct issue lol
To be a proper RV recall they will need to notify you to immediately get to a service center where the technicians know nothing about it so it can sit for a month while they learn what to do.
then they will order the repair parts that are on indefinite back order out of China that way your unit will sit until the warranty runs out and then you can have it back with a two dollars hose clamp from NAPA installed to the manufacturers recomendation
feel free to correct any inaccuracies in the statement
