Hey Gang,
Just bought my 14 S85 a week ago and was hit with a bunch of error codes last night after charging stopped unexpectedly (low voltage, reduced power, can't start). This morning the codes cleared and the car seemed fine so I backed out, put it in drive, and got a "may not restart" warning. At that point I drove directly to the service center 15 minutes away. After checking in with the tech, he said they received both internal and external isolation faults so the battery needs to come out immediately for fear of a "thermal event." The battery was pulled and it was discovered that the fuse cover corroded so it's assumed water got inside the unit. While they have not said it yet, they seem to be leaning towards a new battery being needed. They are waiting for specialists to come and discharge the battery so they can get a look. It was stable and not overheating, which gives me some hope.
Being that this is outside of warranty, a $20k expense on a car I bought for around that amount is not sitting so well with me. I am open to advice on what my next steps may be and anything I should make sure to do at service (get the cover? Ask them to check the fuses? Ask to see the HVB if they deem it unfixable?) Also, if they decide they need to replace it, does the old battery become my property to sell? I asked about this and the tech seemed taken back by it. Said he would look into it.
Thanks for any and all help. I knew this was a possibility but thought it was remarkably rare.
