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.Interesting. So it would seem all this software flash does is it adds some monitoring for a suspicious (but not necessarily abnormal) condition, and disables charging, or even driving the car entirely, thereby forcing a tow to a dealership again for another unspecified repair (possibly hv battery replacement).
I wonder how many such faults we will start seeing after this "remedy", and how many of those will turn out to be false positives.
