The Silver Lining of a 21-Day Dealership Stay: Vampire Drain Edition
If you are looking for the absolute bright side of your 2025 Volvo EX90 sitting at the dealership service department for 21 straight days, I have some good news: vampire drain is basically nonexistent.
Back on September 11, my EX90 with 12,000 miles on the clock threw a tantrum with "energy supply reduced" and "critical electrical fault" warnings. The technician tracked down the culprit: a faulty GHCA. Fast forward to today, October 2, and I'm still waiting on the GHCA to be delivered to the dealership.
With the car bricked and running VCU2, it only suffered a 1% battery drop over 21 days.
Fingers crossed I get it back before it celebrates a one-month anniversary in the service bay!
