Finally got the seemingly inevitable "Service High Voltage Charging System" message

Took almost seven years but the sensor seems to have failed. I have WOT's bypass on order but it didn't arrive in time. I have a dealer i really like so it will be interesting to see how it handles this issue. Wish me luck.

You know the drill. More than likely they will go through a bunch of diagnostics, find nothing, finally change out the sensor, clear the codes and call it a day.

Did you order from WOT? Might be a long wait unless the assembly line is going again.

Checked your coolant levels I assume. If the sensor is flaky, you can clear the code with a code reader and it will let you charge, but it'll refire as soon as it hits full charge again. If the sensor is dead, it'll refire instantly.

Yes I did check the coolant level. I'm calling the service advisor to make sure they have the sensor replacement. Shockingly they have listened to me when I had a suggestion. Or at least pretended to! ;) I'm hoping I can convince them to just replace and test and not go through the protocol. I have an extended service plan so it may be covered. They are really good at customer advocacy so they might also treat it as part of the powertrain. Will be interesting.

Good suggestion. First thing I checked, though I was 99% sure the coolant was not low. And it wasn't.
