Windshield Wiper/Washer Fluid Question
Happy Sunday! This forum is great! I've had my new car about 3 weeks now and during the rain, at times the windshield wipers stick when being turned on, however, the faster they go and the more it rains, they tend not to stick. I assume this is normal because the car is brand new, and I also had the dealer do the ceramic coating.
Also, when they stick during light light rain, I press the windshield washer fluid button just to spray a very little amount, and they no longer stick. My other question is, is there a certain washer fluid we should be putting in these cars? I almost never use washer fluid so I'm not worried, but is there a certain ones that we must put in? Also, when we go in for service (mine isn't due until next summer), do they fill up the washer fluid tank as well? I would imagine they do.
Thanks!
Regarding your wipers sticking. Can you elaborate on that a bit? When you say stick, do you mean the stop at some point on the windshield and just stay there or that when they change direction it seems like they briefly stick to the glass and you hear a noise as the motor forces them to move in the opposite direction? Or, are you talking about something else?

Sounds to me like it's just friction between the blades and the glass. Maybe you glass needs a good cleaning or the rubber on the wipers needs to be cleaned. When the blades reverse direction the rubber has to flip over to the other edge which can sometimes make a noise. It could be that they are stiff and need to work themselves out over time. I wonder if the dealership put ceramic coating on the glass as well and if that isn't having some impact here where it's causing this to occur. I would think the opposite as the coating would make things much smoother.

Thank you!
On another forum I posted that putting Rain X on the windshield, not the windshield fluid, but the actual product may cause problems with your wiper blades.
From my experience wiper blades are like skis: from the factory they are best and with time get worse. IMO, the are not getting better or breaking in: the ceramic coating is wearing away - you mentioned that after the car wash. The fact that when either you use your spray or it is raining hard, the problem goes away. The spray eases surface tension, while heavy rain your blades are going faster.
What I suggest is that you get a good glass cleaner and do your entire windshield. This should remove the ceramic coating which I believe is the cause of your problem.

Took it to the dealer and they changed the blades and issue gone.
