may want to have them check it out then or check for leaks towards the left under side of the cowl when you are looking at the engine bay from the front as you should get a very wide full spray pattern out of the nozzles where the fluid comes outMine really does not sweep the fluid up very well.
I did this with mine a couple years ago, even though I have twin stream pattern, not the fan pattern. Took a bit of adjustment not to over do it, but was eventually perfect at all speeds. It needed adjustment when I went to single wiper, then back to double again. Let us know how it works, even though this is definitely a safety concern and Nissan would be smart to hastily rectify
We have purchased two 2014 versa notes my wife and i and they both spray fine. The problem some of you are having sounds like ether the washer sprayer pump assembly is not producing enough pressure, there is trapped air somewhere in the lines, a small leak in the lines somewhere or an obstruction in the lines.
