After Ford's handling - or not handling - of the charging subsystem recall, I decided it was time to move on. Ended up making the full BEV leap to Tesla Model Y long range. Looked at long-and-hard at the Mach E, came to the conclusion it really wasn't competitive in the areas I cared about, like energy efficiency and particularly pricing. Models comparable to the LR were stickered like $10K more - without eligibility for the Federal tax credit or dealer willingness to get even close to the same $$$$. This, coupled with Ford's lackadaisical attitude for product support for anything that's not a honking big truck made me look elsewhere. I know, might be leaping from one frying pan to another - guess time will tell.

What area is it coming out of? If there aren't other problems, maybe something like an axle seal or cleaning and re-sealing the case joint could resolve the problem for lots le$$. Lots easier than swapping the psd (AKA transaxle).

Well, the saga continues. Got a letter from Ford today for a $250 offer for 'not charging your vehicle'. OK, then. So I guess that indicates that the 'fix' is nowhere near?

Well, I got a recall notice above - with no resolution described, but promised for a future date. The described fault / risk is that the Battery Energy Control module can fail due to overvoltage / current overload. The immediate work-around is to stop the plug-in, with a promise of some future fix. That makes the Energi compromise (lack of luggage space) really had to swallow. My typical driving pattern is within the daily plug-in range, so it's several months between gasoline purchases. Now, the charger I have been using can throttle the current - the current observed max has been 14 amps (from the 240 volt circuit), topping up the battery in a couple of hours. IDK if the risk is just with the Ford-branded charger, or what the exact scenario is. That new Prius Prime is looking more appealing with each of Ford's mess-ups...

Get someone with a scan tool to pull the codes for you. The ECU is detecting a fault and going to 'limp home' mode. Without the fault codes, it's all guesswork. And way to many parts to fail without the ECU telling you 'where it hurts'.

Yeah, good luck with that. Ford can't (in states with 'mandatory franchise' legislation) / won't (elsewhere) do anything about stealers charging > $10K for in-demand vehicles or thievery on delivery (surprise add-on charges when picking up a vehicle) for folks that ordered vehicles. And their actions show they don't give 2 flips for for folks that prefer sedans. This kind of 'forced obsolescence' BS has been a thing in consumer electronics and the greed cancer is spreading to vehicles. Other marques have had the 'subscriptionitis' (e.g. BMW charging for android auto as a subscription and is now charging subscriptions $$$ for features like heated seats). This kind of BS will continue and grow as long as sheeple put up with it.

Well, it's officially offline. "App has been de-activated" message and subsequently uninstalled. Now to figure out how to delete account and related data. I guess the end of data leak will be a plus. Is there a way to disable it, since there isn't a 'legitimate' connectivity? In wireless, any open connection service is a security risk, particularly one seeking to connect. I was never able to get a straight answer on costs. This is definitely not a thing worth a subscription or $$$ in 'upgrade' cost. One of the bigger turn-offs with GM brands is the 'On-snoop' and its subscription $$$ and the inability to disable, even when not subscribing.

Thanks. Called a service advisor yesterday, asking for $$$ for the program. No response so far. My case is a bit 'different' in that the '19 is nominally a 2 year 'promo period', but I purchased the car in September '20 as a CPO, which supposedly increases the 'promo period'.

Well, yeah, ATT 3G network is shutting down. ATT site states 'end of February 2022' for their wireless customers. My question is whether other folks are using the MyFordMobile app and whether anyone else is getting the message. Also, has anyone gotten the $$$ figure on 4G upgrade. The app notice states 'talk to your dealer' - and we all know how much fun THAT is (like trying to find someone who can actually give a straight answer).

Just got a notice that MyFordMobile will stop working by the end of this month, and to contact the dealer for cost of a 4G MODEM. Car's a 19 Energi Titanium. At one level, having less snooping and data leakage is good - at another somewhat annoying. Anyone else get a similar notice.

Can't help but wonder if this is a consequence / malfunction of the ANC subsystem. On a prior vehicle with ANC, had an issue where the 'drone' it was supposed to cancel would actually be made worse by the ANC. Kind of recall it being a microphone problem along with a bad speaker. Replacing them made it better for the remainder of that vehicle ownership.

The drop may be from the increased rolling resistance, or from the cold temps and 'winter gas' encountered when the snows are needed. Or a combination of both. Low rolling resistance tires are key to keeping the MPGs as high as possible.

The root cause could be one of any number of things - ranging from something as silly as a loose connector, to damaged wire, to sensor or rack failure. The diagnostic steps in the service manual would be a good place to start - although that will reference the factory scan tool that is too pricey for most DIY folks. With the current crop of computer-networks-on-wheels, a scan tool is a first step to having the car 'tell you where it hurts.' A visit to the dealer or a qualified specialty repair shop would be in order if you haven't the scan tool resources.

Well, the miles racked up do represent accurate distance the chassis has traveled, even though there are components that haven't been in use. Thus the miles shown represent wear experienced for the wheels, tires, hubs, axles/CV joints and the transaxle, even though the ICE hasn't run during that time. In some ways it's the obverse of what certain ICE-only fleet vehicles (e.g. police vehicles) experience, where the miles logged are substantially below the hours spent 'idling'.

You have obviously not driven certain Toyotas with the 3.5 and the 8 speed. In the quest to maximize efficiency, light incremental throttle input from moderate speed cruise will do a 'herk and jerk' until the ECU decides to command a downshift. Work-around is 'aggressive' throttle input. You are right that most manufacturers do a good job of tuning out 'lugging' behavior, particularly with automatic transmissions. The real cause is combustion instability - the combination of ICE load, and valve timing, ignition timing, EGR and RPM yields unstable combustion which shows up as mechanical roughness due to 'wrong time' cylinder pressure peaks. The 'float on oil fail' isn't really a cause - more like a consequence of peak pressure exceeding oil film strength. Any significant duration of that will destroy bearings. Smooth ICE performance requires peak cylinder pressure some time after top dead center of the power stroke - exactly how many degrees depends on the piston / crank / con rod geometry. It also requires a smooth build of pressure - pre-ignition results in multiple local peaks that load the piston surface unevenly. This result in resonance / flop that is audible as 'ping'. I don't get what you're saying in 'pumping losses on coasting'. With many modern ICE tunes, the fuel injection will effectively be shut off, thus no loss - the pumping is used to slow the car down. Otto / Atkinson cycle pumping losses are at light-load cruise, where manifold vacuum is high. That manifold vacuum requires flywheel energy to overcome - leading to a less efficient power output. That is one of the things that makes Diesel cycle more efficient (other being high expansion ratio) - running without throttling air minimizes the pumping losses on the intake cycle to the pressure drop across the valves. As to minimizing RPM - that is really about minimizing frictional losses, including hydraulic losses. Higher ICE RPM have more friction overhead.
