Air blower, defrost, and heat failure in heavy rain creating a dangerous situation while driving 70mph on a two lane highway with oncoming traffic. I could not see and had to pull over. Visibility through the window became low very fast. Two years ago the same issue happened. The dealer updated software which fixed the issue, until now. When my vehicle was in the shop, they had another in as well with the same issue and they couldn't find a solution. The software update did not fix the problem for them. Long forum posts on the internet with many people having the same issue.
