Hi,
I just reviewed what we have discussed so far. I have a few questions. First, you mentioned that coolant was going into the engine. Is that correct? Did it have a faulty head gasket?
Next, I need the specific model you have. See pic below.
Last, you are correct, the engine, aux battery, and hybrid battery are three different things. Also, if there was coolant leaking into the engine, it may have caused internal damage, but there is an aux battery (traditional 12v) that starts the engine. They could have tried charging or something different if the battery was still good.
Let me know.
Joe
