It did not hit me until this week, i was driving, and needed to clean off my window. I hit the spray button and nothing. I thought hey, wait a min, does the WRX come with a warning light that tells you when the water levels are low? It does not look like it, i pulled up and filled up the tank and off I went.
Those sensors are cheap to install, most cars have them, why the WRX does not is beyond me. Anyone know if there is a good reason why Subaru thinks a low water level warning is a bad idea?
