My 500e died unexpectedly last night. I restarted it several times and even jump-started it, but with no success. I needed to have it towed to the dealership. They identified the problem as a dead battery, which I expected given that my vehicle is a 2019 model. However, they later called to inform me that the Power Inverter Module (PIM) also needed to be replaced, at a significant cost of $16k. Is this legit? Has anyone else had issues with their PIM?
