NHTSA's summary

Supersedes Technical Service Bulletin Group 92 number 14-09 dated September 12, 2014. The washer solvent level warning is on in the DIS, but the washer solvent level is correct. There is no functional restriction in the windshield washer system. The sensitivity of the washer solvent level sensor (G33) can be affected by the type, concentration, and the presence of additives in the washer solvent currently in the tank. The operation of the level sensor relies on the composition of the solvent to provide an accurate message on the solvent level. Incorrect concentration and the presence of additives can contaminate the sensor and reduce its sensitivity.
