46000 and a new problem

Hit 46,000 miles this morning, only 4000 to go under the warranty. I realised on the way to San Diego that I have a new issue: the rear wiper washer isn’t working, no water is coming out even though I filled the reservoirs just this weekend. I’ll get that done in the next couple of months and it will give me an opportunity to get the V.39 upgrade also. The service indicator is telling me that the next service is happening at 50,100 and I assume that will only get larger in the next 4000 miles. Bummer, I was hoping to squeeze one more free oil change out of the warranty.
