My point was that it is a 50-state Federal requirement that the battery have an 8-year warranty. But in CARB states (which is supposed to include my state of Pennsylvania) , the required warranty is supposed to be 10 years or 150k miles.But new york and California have extended the EV drivetrain warranty by law.
But MB because of that little descicant, will deny any warranty if you did not buy new one from them
Regarding the dessicant, I would think that that would fall under laws that manufacturers cannot mandate dealer service or manufacturer-only parts to keep a warranty intact. The idea that only MB's silica gel is the only "legit" silica gel is laugable. It's like a tire maker requiring that you use only "their" air for the warranty to be intact.
