Today, I experienced the coldest temperatures yet on my drive to work. At one point, I saw a '24F' shown as the outside temperature (although not unusual for April in Minnesota): Expected: My gas mileage was down a bit. I was impressed it wasn't as bad as I would have expected from our 2005 Prius, though. I should have expected: On the last 1/2 mile or so, when driving slow on the little bit of EV left while in the forced HV mode, I accidentally accelerated too much and forced on the ICE again (it had been previously on earlier in my 22 mile commute). This time, however, it was different because it didn't shut off immediately. I think the ICE had to do a second warm up. I'll have to watch that more closely next time (darn that cold weather)! Not expecting: When going over bumps, something started rattling near my car's glove box. It was not from anything within and it had never done this before (in warmer temperatures). It was very annoying (and it did not return when things warmed up for my ride home from work). Anybody else experience rattling noise? Any ideas about what I could do? I sounds like something is loose. I don't want to be hearing this all winter next year!
