I wonder if hybrid being more reliable than gasoline cars is simply a function of most of those being Toyota, versus any effect stemming from the car being Hybrid.
My Toyota hybrid reliably does not start after 4 weeks not driving. The 12 volt (1 year old) battery is drained too much after such a period of inactivity. I was not expecting this from Toyota, pretty disappointing.
But I blame the car's smart features (that use the cell modem to allow remote start, etc) rather than it being a hybrid. I suspect that the non-hybrid model would be the same.
