Redshift

My 2015 had this issue. Took it to the dealer who did the TSB. That was 2 years ago. Never happened again. BTW they don't replace the AC fluid. They just make sure it's full.

All the energy doesn't come from the ICE for charging. Don't forget regenerative braking. Also don't forget the battery is charging whenever you are slowing down or going down hill.

How can the A/C hit the battery hard? It runs of the high voltage battery that barely notices the drain.

You guys are missing the fact that the A/C on the C-Max is ELECTRIC, thus no parasitic drag whether it's on or off.

Every time I buy batteries at Batteries Plus, they install them for free. I even replaced the battery in a beard trimmer that required soldering and they still did it for free.

You proved my point with your link. There are no cars listed there older than 2016. I have a 2015. Also, I have Sync 2, version 3.8 that hasn't been updated since October 15th, 2015.

Great. Does that mean they are working on a software update for all the Sync 2 users?

Just went to Ford's site to see if they have any upgrades for Sync 2. Since the site knows I have a 2015, they recognize me. Under the Sync tab, I cannot even click on anything, like choose your year. It's all greyed out. Guess us millions of Sync 2 owners are just left to fend for ourselves. This does not give me a good impression of Ford. The site has, in small text, a notice that the site is only for Sync 3. Thanks Ford. :-(

Such a ridiculous price for something that is super cheap to produce. I bought a Garmin GPS and a temp mount (a sandbag) so I use it only when needed. Cost? $150 with FREE LIFETIME map updates.

And us poor Sync 2 owners are left out in the cold. No worries. There are only 10s of MILLIONS of us.

My 2015 has it.

According to Ford, the USB ports support all types of devices for charging. They say that .5, 1 and 2 amp power is available depending on your device.

The ICE in the C-Max does NOT switch from Otto to Atkinson. It is always in Atkinson mode.

Agreed. 6'8" here and I can wear a hat while driving my C-Max.

Went to another town for a retiree lunch and look what I happened to park next to. 2013 C-Max. What are the chances?

That is logical except that driving out of the mountains, my C-Max used the ICE constantly to help slow the car, even after the big battery was completely full.

With a fuel injected car, it doesn't save any gas when coasting downhill in neutral because the computer has to keep the engine running, thus using gas. All modern fuel injection systems turn the gas flow completely off when coasting in gear. The forward momentum keeps the engine turning with no gas use at all. So driving in neutral uses more gas.

My 2015 SEL just started making this noise about 2 weeks ago. 13,200 miles. It's intermittent also. I cannot make it happen on purpose. Sounds like we may have some kind of issue.

If it lost 20% power I don't think it would be "vastly" better than a gas car. The diesels only get a couple of more mpg than a hybrid so a 20% loss would be a big hit.

It great to be able to say you get that kind of mileage but I don't believe it's worth it taking an chance of damaging your fuel pump. Since the fuel pump is in the gas tank, it uses gasoline to cool itself. Run the tank super low and your fuel pump is exposed to the air and gets hotter. I'd rather fill up earlier and save my fuel pump. Doesn't mean anything to me personally about how far I went on one tank but you mileage is impressive.

FYI using premium gas will NOT improve your engine life. It has nothing to do with it. Just use a good grade Top Tier gasoline and enjoy your car.

Just curious. Why don't you want the a/c compressor to come on? Mileage? It's not going to make that big a difference. Also, if you don't run your a/c occasionally, the seals in the unit will dry out. They use the coolant to lubricate all the fittings so it it never runs, they will dry out and crack, thus causing a leak and expensive repair.

That's not true. My 2015 C-Max SEL headlights will come on automatically if I have rain sensing wipers turned on and the headlights set to auto. I had it set like that for a 5k mile trip I took this summer. Worked like a champ. I never had to worry about the lights or wipers.

C-Max has been on the road in Europe since way before 2010. It was 2003 when they first came out.
