First of all, there is always going to be wear and tear on the battery, but depending on how you treat the battery, there could be more excessive wear and tear that many are seeing here now. I've been trying to preach how to take care of the battery for the last 2+ years, and many at the time discarded what I said and decided that Ford should have designed everything perfectly and that no worries just plug it in all the time so its always ready to go. The trouble is, some people went beyond the car's design and intended use by trying to not use the engine at all which aggravated the issue even more.
Well unfortunately and sadly many of you have managed to damage the battery, most recently my buddy Ansy, even though I've told him stuff he chose to ignore it and always plugged in the car, sometimes driving on the highway at 70mph when he was late to work this year (and I told him don't do this start the engine), plus charging in the heat so he could try to always go on battery. Well that's all water under the bridge now, but my problem with this is that it is unlikely and not economically feasible for Ford to replace everyone's battery. Sure I would love to get mine replaced as well, and conceivably I could damage it on purpose to get that done, but is it really fair to Ford? I don't think so...You guys may be pushing Ford out of business if they had to replace all the batteries free for everyone.
Just thinking out loud here, what's your opinion about this?
Sorry Raja, I don't align with your position. The way you phrased your comment seems to me to be putting responsibility for the battery degradation on the owners and their driving/charging habits, not on Ford where it belongs. Ford could have either designed the software and/or cooling system to prevent accelerated degradation (such as preventing charging when battery is hot, limiting upper charge at 80%, etc.) or at least given specific instructions in the manual what to expect. But that would have alerted potential buyers to the issue - why pay extra for an Energi if in 3-4 years it'll be driving like a Cmax Hybrid?? Or specifically state in the warranty that what they guaranteed was it would run as a hybrid, which only requires around 2 kwh capacity, not the 7.5 kwh they needed to qualify the car for EPA and IRS rebates as a PHEV. Either of the latter would have alerted buyers to the issue coming down the road, that many of us now are facing. You, and several others, have used extraordinary measures to preserve the battery capacity, in some ways (at least to me) limiting your use and enjoyment of the car. If I have to hesitate accelerating to 70 MPH on a highway, or coasting in neutral to avoid regenerative braking or discharge, or never charging twice in the same day, then it ain't fun no more. So now that Ford has told me my 5.3 kwh maximum capacity is down from 7.5 due to 'normal wear and tear' with no definition anywhere of what IS normal, my options are to 1) pursue in court of either public opinion or legal (as in a Nissan Leaf-type action); 2) enjoy my hybrid Cmax with some PHEV kicker or 3) whine. Whine is not an option.
