Well part of the issues I can't talk about until the security module is replaced. That said my car must have sat in the desert for a month or two. Look at the back of the engine: I spent hours washing, waxing and cleaning this car. If it wasn't a case of needing a car right now, I would have just told them to order one.

I'm pretty sure they are talking about the display: http://www.motorcraftservice.com/vdirsnet/OwnerGuide_EU/MainContent_Test_Layout.aspx?year=&model=Fusion%20Hybrid&bookcode=O21825&market=US&language=EN&chapterUid=G1518974&subUid=G1526211&topicHref=G1526212 It should say "Release the control when you reach the desired speed on the display." Granted it doesn't say that, but that was the meaning, based on my own experiences.

So a couple of things, words like block and reject are marketing terms. You care about absorption and reflection. A material may "reject" a wavelength by absorbing it, and you're no better off (the material heats up and then radiates that energy out, right into your car). 3M specifically talks about reflecting; however, this is not quantified. I mean you don't really want to know what you're buying, right? So a brief talk about wavelengths, energy and absorption. Take a gamma ray. Lots of energy, very hard to produce. 100 keV. Can go through most thin materials without breaking a sweat. The wavelength is tiny. Smaller than an atom. In order to absorb such a wave, the energy of the wave must be completely transmitted to the object. Usually this translates into heat, by vibrating molecules. In some cases (especially with high energy waves) this will result in knocking an electron off, damaging DNA, etc. This is why sunscreen works on ultraviolet light. Damaged DNA leads to mutation which generally takes the form of cancer. Nasty stuff, wear your sunscreen people. On the other side we have radio waves. (Sound waves are a result of compression of air, not strictly part of the EM spectrum.) Radio waves are long. Very long. The energy needed to create such waves can be as small as a 9 volt battery. (Actually smaller but you get the idea.) So absorption of this energy doesn't result in much heat at all, which is good. Take for example 2.4 Ghz, water absorbs that range especially well. That said your WiFi router doesn't give you the equivalent of a sun burn. But in greater doses it can be used to heat food, in what's known commonly as a microwave. That's right kids, you want to know why your WiFi dies when you start making popcorn? The microwave floods the area with 2.4 GHz radiation and chokes out your signal. So where does this leave us: Small wavelengths = lots of energy Long wavelengths = less energy So it turns out that ultraviolet waves are shorter than visible waves (starting at violet going to red) and visible waves are shorter than infrared waves. So which wavelengths would you like to reflect? Well if you're trying to prevent energy transfer (keep the inside cooler in the summer based on energy from the sun) the longer wavelengths are your friends and should be invited to the party while rejecting the shorter wavelengths. Oh and don't be fooled, visible light does generate heat. Remember what you see is only the light that is reflected, not what is absorbed. Okay so all this talk, but no conclusion. Well, remember your dash is mostly black, so any and all light energy coming through the front window will be absorbed and radiated. While tinting can help a little with this, the three biggest factors will be, the color of your car, can heat escape and if you can block all the energy. So use a windshield screen, preferably in white or silver on your front window. That will work the best. Tinting at best will have a minor effect. We're talking .1 MPG, if that. Cracking your window so heat can escape would do more. Also white cars have much less heat gain, due to the reflection of all visible light. TL;DR version: No, tinting won't help your MPG in the summer. Have you considered cracking your windows?

I found the news report confirming the complaint.

Do you have a delay between starting and having it say ready to drive?

Pretty sure it doesn't, Mazda broke with Ford a couple of years ago. I could be wrong.

Well the key is, the charge isn't fluctuating, only the measurement. Think of it like using boiling water to measure temperature. At sea level it boils at 212. Well if you go to the top of Mount Everest and boil water, you might assume that means the water is 212, when in fact is is only 167. (Granted at the top of Mount Everest, you don't really care, you just want something warm.) The air pressure (as a function of elevation) is a hidden variable in your temperature measurement, it can be accounted for, but only by using other devices to determine your altitude and some math. In much the same way your battery level measurement depends on the hidden variable of temperature. Or in other words, it isn't a fairy who's adding extra charge. It is a gremlin who's messing with your measurement.

So I tested the 2014 Mazda 6. After having an '06 with 6 cylinders, the 2014 4 banger just didn't have the performance I was used to. I couldn't do that, knowing with the right engine, that car could do so much better. It was a let down. As I said elsewhere, the '06 Mazda 6 I had didn't hug the road, it made sweet love to it and cooked breakfast in the morning.

You're right, I misremembered the technology. Still, heat changes the measurement. Using Ohms law I=V/R or V=IR. Since R increases, I decreases. But because R is assumed to be resistance at normal operating temperature, the computer estimate may be off, especially when starting a cold engine. Now you can use thermistors and correct for such deviations or you can wait for the engine to heat up. The former requires more hardware and software, so Ford likely went with the latter.

Two things, as the heat increases, so does the resistance over the wires: https://en.wikipedia.org/wiki/Electrical_resistivity_and_conductivity#Temperature_dependence In addition, LiPo batteries must be kept below a particular temperature or they will fail. The computer may be estimating that cost in (battery drain) when you turn your car off, but not when you first start it up.
