It’s hard to say exactly how the new software will work. But from what I read, Chrysler expects to determine if you have a faulty battery pack or not by merely monitoring a single charge/discharge cycle. Apparently after performing the diagnostic at the dealer they will “ok” the van to be used as intended with overnight charging and parking in a garage.
Yes they will do one test cycle in the shop. But the bulletin is also very clear imo that the software will also do some form of it afterwards and will disable the car under some unspecified conditions.
What makes me unhappy is that these conditions are not straight abnormal, otherwise they would have programmed that fault in long ago, including the new year models as well. Yet in 5 years that passed since I own the car, these cars are to get this new fault analysis only now.
The next logical step in this reasoning is that since the condition is not outright abnormal, it will likely cause false positives when the battery fire is not imminent and the battery does not require replacement.
That is, it is not too far fetched to assume that instead of 3 fires per year we will get 50 faults per year maybe more, hopefully without fires (but I wouldn't bet on it), depending on how much faith we are willing to put in this fix.
I am not putting much because nobody have ever had any tests on the population and figured the false positive rate when these conditions did happen without fires.
If I have my car disabled, knowing my dealership, it will probably take them two weeks just to squeeze me in for another 2day battery test, and who knows how much longer if they actually need to replace the hv battery. I imagine month overall is not entirely out of question at all. All the while the car is undrivable. We've seen similar things happen during this car launch already, cars ordered and built and in some cars even already paid for, held without clear cause or remedy for months.
If it happens while the car is in the garage, I am not sure the tow company will be even able to pull it out since the car does not have manual release.
Also, it is not that they never issued a software update before on this car that they had to issue another recall for just to revert some of its bugs.
No way I am playing this game this time. If I am getting this fix, it is either if it checks out on the population for a year or so, or to sell the car to make it recall free on paper .
