I was finally told today, after several bouts of no EV on my 2014 Crosstrek Hybrid, lasting,1 to 3 days, that running the front windshield defrost PROHIBITS the use of the fully electronic engine. I came to this conclusion serendipitously on my own, but was not offered this explanation until today, after many phone calls and return visits to the dealership. If someone from the dealership had just asked if I was running the defrost, I could have avoided a pile of frustration. The dealership said that they were simply not aware of this problem, because the car is so new.
I am not happy about this limitation, but may have to live with it if others here are having the same experience.
*Does anyone know of the best method to try to contact other Crosstrek Hybrid owners to gauge the validity of the explanation I was given regarding the operation of my hybrid? I have already posted to the Subaru forum.
