If anyone else has seen this issue please let me know.Have you experiencing HP laptop high pitched whine? If you are getting this problem, then it is sure that major part of your computer has been failure, broken, loose or about to explode. I have seen a few other threads about this, only useful info was to replace the aux battery, but it was new 8 months ago, I dont see how it could be shot already. Having her look for codes now, but no CEL was shown.

I had her check the maint menu on the MFD, the 12v bat shows 11.9 volts, but this is probably a little low because we have been turning it on/off a bunch trying to figure this out. The MFD shows the traction bat at 50%, it appears to drive fine. She left the house this morning and drove ~20 miles without issue, couple stops, then she gets in and it starts this beeping. There are no warning lights on, no ABS flashing, no triangle, no codes, no open doors. Today my wife calls and I could hear it on the phone, as soon as she presses Start, there is a loud wine over the speakers, it does not stop, even as she drives it will not stop the loud beep/wine. It consistently gets 46-47mpg, running great. I have a 2007, 175k, replaced the 12v battery in January, and reconditioned the traction battery with 1 new module.
