How fast is the OP driving on the highway? If you're going close to 80 that's the problem.

I found the reference to the 91 octane in the 2017 owners guide. I can't imagine why they put that in. Putting higher octane in an engine designed for 87 will absolutely not produce more performance unless the engine can increase the compression ratio. To my knowledge the method of mimicking Atkinson cycle operation with these engines by variable valve timing can only "lower" compression ratio. There is no more chemical energy in 91 than 87 but by raising the combustion temperature and pressure you can improve the thermal efficiency slightly within the confines of engine material temperature tolerance. The added cost of 91 cannot be justified by the efficiency gained. Now let's talk about politics.

That link about the Fordservicecontent yields a "404" error for me.

We've found the car's computer reports mpg about 4% high but the odometers are about 2% low so the net is about 2% high or about 1 mpg.

There's a TSB to increase the electric water pump's speed with software. Tell the dealer to look for it. There have also been reports of problems with the electric system's temperature sensor, connector and wiring. I couldn't find the info on the motor speed increase for either the 2010-12s or 2013+s.

Have the check engine and other warning lights gone out? You talked about the generator earlier. The "Generator" is one of the two big motor/generators that are part of the transmission. It controls the transmission ratio which is continuously variable. It can act as a a motor or a generator turning in either direction while controlling the transmission. Sometimes it is not turning at all when the car is in motion or when parked and the ICE is off. In "P", you can make the ICE start by pushing down on the go peddle about 1/3. You can vary the rpm a little by pushing the peddle to the floor. When you do that does the noise sync with the RPM? I think only Ford may be able to diagnose this.

It's a bearing quality or lubrication problem. It's a "Sword of Damocles" hanging over all those models.

The TSB mentions cars built before 8/15/15 so it includes early 2016s. What a bummer! Out of warranty 10 hours of labor plus the transmission.

I thought Teslas used BlueTooth when in proximity.

All of them still burn fuel and they already have the hybrid technology and they still have the same profit centers for the manufacturer and the dealers. The lower servicing expected of pure electrics wipes out most of the dealer profit center and completely changes the current manufacturer-dealer relationship.

They may think the electric car trend is something they don't want to invest in right now and the pickups and SUVs will be the last ones electrified. They claim the margin is small on the cars so maybe they will hoard cash for the eventual huge investment the change to electrics will cost. There have been several financial analyses of why the huge fossil fuel car companies will have a gigantic problem switching their business model from fuel to electrics. The profit centers are completely different but they still must service the debt on the present business model. Tesla has a huge advantage because nobody expects them to make a profit soon and in the unlikely event they can't get more financing in the US, China and India are ready with billions. Musk would rather his US company makes them but his view is much broader and if the US wont he'll go elsewhere. People are dying from pollution everyday in China and India.

I have had the low HVB three times in the last two years. The car will now not go as fast in EV and the display of available EV power is not as high as it once was. I believe the events are a cell permanently shorting. This doesn't change the total energy capacity much but it would lower the voltage and maximum power output capability. I usually have had a reconditioning event every 8000 miles but I haven't seen one since this started. Maybe once a cell shorts it is inhibited. I don't know what this bodes for the future. HVBs can tolerate shorted cells but not open ones as all the cells are in series. There are 204 cells in series so if 3 are shorted that's about a 1.5% voltage loss. Available power is related to the square of the voltage so peak power loss would be 6%. EV operation needs higher voltage the faster you go because of "back EMF" (voltage) of the motor so the maximum speed may be inhibited even more than the 6%.

The water pump(s) are electric.

This is all BS from this dealer. Try to take it somewhere else. This car is designed for the engine not to run a lot.

I just ran them through the tops of the windows across the inside of the car just below the headliner.

OK.

I think the point is the report was sent to your designated Ford dealer which now will not be done. Ford has been going downhill since CEO Malally left in '14. All they care about now is making big profits from the pickups and SUVs.

There was no recall on the 2013-14 transmissions which is the problem. After that they seem to be OK. Actually there is no maintenance on the eCVTs other than perhaps an oil change.

Try some unleaded with ethanol. Why do you not use gas with ethanol? Gas without is much more expensive and the performance/mpg increase not cost effective.

I think the transmission problem was only on the 2013-14 but I get your point.

Use Google Maps/Drive on your smart phone.

Ford's Owners Guide says it should last the "life of the car". They've had a low failure rate. Keep it.

Push down about 1/3 on the go pedal and the ICE will run as long as you hold it down. It won't run to maximum RPM, only maybe about 2000.

You didn't answer whether you obtained the car new? If not, maybe something happened to it before.

Since all the regen is done on the front wheels, the system balances it for stability by applying rear mechanical brakes unless you are very light on the braking. Brake score may be the gauge and 100% may mean no mechanical braking.
