Shift to Park issue out of control

Hello Everyone,

Hope everyone is having a great day.

I wanted to get the community's opinion on the phone call I just got from the dealership.

My 2017 Volt has been having intermittent "Shift to Park" errors over the past few years. Nothing major, it only ever happened while it was parked so I just kind of ignored it. Well yesterday it wouldn't move. Kept getting the action required message, shift to park. I could move the shifter into all places but the car wouldn't actually move and the steering wheel was very hard to move like the power steering pump wasn't on. I had to call a tow truck and have them tow it to the local dealership yesterday afternoon. I called this morning, the service guy was on the phone and I was told he'd call me back. About 45 minutes later he calls me back saying they need my permission to drop the high voltage battery and it could be up to $5300 charge for diagnosis because the codes they pulled "are leading them to testing the battery". He said that figure includes the labor and parts that could potentially break while they are removing the battery, bolts, a bar, etc. He said if it needs a battery it would be $19,000. Then he said "When these EVs go bad they are expensive."

I asked him for clarification on what would warrant a new battery. He said he has to ask the technician for that and he'll call me back.

It's got $120k on it. The battery control module (BECM?) was replaced about 5 years ago under warranty.

I mean I understand his attitude towards EVs from his comment but I hate his attitude which comes across as "that sucks for you."

Anyone have experience with this issue on this car?
