Longer charge times and reduced battery storage were not mentioned in the ABC report. Here is more info about the petition:
“Tesla installed a “software-induced” limit on the total number of usable kilowatt hours on the affected vehicles, limiting the ability of owners “to charge the battery cells up to the natural and normal amount of approximately 4.2 volts, by placing … battery capacity limitations, by decreasing the charging speed … and by reducing the performance in terms of speed,” according to the charges.”
