bad starter?
Hmmm. That doesn't sound so good.
When the 12V batetry goes dead long enough for the car to "forget" the charge in the 144V, it will refuse starting with the IMA and use the conventional starter instead.
Having said that, the car should behave exactly as any conventional car with a dead battery. So jump-starting should follow the same routine.
The only thing I come up with is a bad starter. You would never notice this during normal use, since the car never uses the starter.
If you have a chance to push- or pull-start the car, try that. Once you get the engine running, it will start re-charging the 144V battery and will use the IMA to start next time. That buys you enough time to go to the shop and have your starter checked out.
