Those of us who tow CMax's and Hybrid Fusions behind motorhomes have discovered that the brake system vacuum pump is always live regardless of key position. So with everything off, if the vacuum leaks down, the pump will fire up and pump down the vacuum in the reservoir.
This is, I believe, what runs down the 12V battery in 3 hours or less when we tow. Every Time our auxiliary brake systems apply the brakes, it uses vacuum and then the pump has to run. This is a big pump, the fuse is 40 amp! This is also why your 12V battery will run down if you let the car set a few weeks. It even warns you in the owner's manual to put it on a charger if you're going to leave it set for a few weeks.
You can hear it fire up when you first open the driver's door to get in. It almost always does this unless you have recently driven it. As these cars get older and the vacuum system gets leakier we can expect the battery to run down more often as the pump has to run more.
This could be one of the dumbest design flaws on this car. I cannot imagine why it's designed this way. Pump should be hooked up to the accessory circuit so it only runs when the ignition is on.
Did this 'feature' get added to the 2013 Fusion hybrids (my 2010 fires up its pump when I turn the key to run (just opening the door(s) won't do it ((not doubting you, just curious))

Waiting for the latest n greatest, sometimes it works out & sometimes it doesn't

Could it just be your (everybody) is in EV mode more these days (cause it's warm/hot) and you can here the radiator fan when its running full tilt boogie (like when the A/C is on) plus the compressor makes a clicking noise when the (compressor) clutch does its thing ((stick your head under a friends gas only car & have them cycle the A/C on & off, your gonna hear lots of strange noises)) this is not to say there isn't a problem but you may be hearing noises you've not heard before that are normal.

I've driven my 2010 Fusion hybrid till DTE was zero several times (never have run it dry) - would guess there is 50 miles or so still left to go after DTE = 0 (built in safety factor ?)

How much hypermiling did you do to get 45 MPG Jus (nice job !) ?
-
Easy way to mechanically disconnect whatever is plugged in ? (just a guess)
-
Good explanation 71, I've wondered about this but had no idea - tnx, you sound so sure, how do you know, inside info, have access to the theory of operation ? (I have no reason to doubt U)

Hello from SE Tx, love the hill country :)

An app to show a customer's driving stats to them in a way that can help them improve their mileage is needed especially your typical driver who seems to think putting gas in the tank and using the go pedal is about all their is to it - don't get me wrong it would be nice if the C-Max got 45 or 50 with little to no effort ...

One of the risks is the big rigs can clear stuff on the roadway 4 wheelers may not be able to (tire caucuses etc.) - if you want to draft see if its okay with the trucker first (at a rest stop or use a CB radio) some don't want someone on their tail, if okay see if the'll change lanes or flash their lights to alert you of something unusual is about to happen.

What is the ICE coolant temp when fully warmed up, is celsius still the default ?
-
Good video thanks - glad to hear no vent mode subject brought up !
-
have seen zero commercials here in the hybrid capitol of the world :nonono:
-
HEB is great, they have low prices and good selection + big on RRR (reduce reuse recycle) green buildings etc - kinda like the C-Max, not much to dislike :)
-
EV = electric vehicle
EV+ = ?

Heard (not real sure) the lower third of the radiator cools the inverter coolant - scangauge with xguage ?
-
Pinehurst NC or Pinehurst TX (if Montgomery county did ya find a good dealer in the area) ?

I went to my local Ford dealer last week & asked about the C-Max, the sales critter asked if that was a Ford - they had 1 SE on the lot, he had never seen one before - granted that was one guy at one dealership but I sure didn't get a warm fuzzy feeling :(
-
How are the eCVT & associated electronics cooled, hope grill covers don't affect this cooling :nonono:
-
Good comments, hope the powers that be see this ! (Come to think of it the A pillars did seem a little large in the hybrid I sat in at the dealership the other day)
-
I wonder if the C-Max hybrid has a cellular modem like the Energi does ?
-
I've heard the Fusion's light normally comes on when the pressure drops to ~24 PSI in any tire - not sure if C-Max is the same - why did CNC's light come on at ~34, did it reset by itself ?

The 2013 gas only Fusion (SE) had the auto stop start option but the 2014s (any trim) don't, what happened (am I losing it) ?
