Is it normal to park your 450h at night with a full or near full charge, then when you drive the next morning, the battery be almost empty and the motor having to turn on?

 

No, it is not. My car's battery doesn't lose more than one bar even on very cold nights. I checked last winter.

 

are you talking about the traction (hybrid) battery, or the regular battery for starting your car? in either case, it's not normal. i would recommend you take your car back to the dealer for warranty inspection/repair.

 

I'm talking about the hybrid battery

 

last night I got in my car and the screen showed that it only had two bars, i drove around for a while and it stayed on 2 bars.. now today its working normal again. I need to take it in I guess
