None of the "solutions" mentioned have worked for me - Auto, voice command, stalk button. They work 90% of the time, but this is a safety issue. It needs to work 100% of the time. Auto has improved with updates, but still unreliable. Voice surprisingly seems to always interpret correctly - e.g. display shows exactly what I said - like "Wipers On", but occasionally claims it does not understand, or does not execute, or takes way to long, or sets to low speed when I need high. Button always works, but always at wrong speed so now I have to frantically punch the button to keep the wiper going at too slow a speed, or adjust wiper speed - sometimes when I'm in a critical situation (fast heavy traffic, windy road, car in front just side swiped barrier or another car because road is suddenly slick and people are slamming on brakes), and the only reliable way to increase speed is working a small display that I can't read at a glance. And that with 2/3 of the (well built, beautiful!) screen real estate worthless to me since I typically don't use Nav, and the car icon is totally useless clutter. Not acceptable.
