UPDATE 1 - BCM2 (Brake Control Module) is being replaced. Will update after I get my car back and drive a bit.
This has happened to me in my '23 XC60 Recharge over 25 times in 6 months. It happened during warm weather, hot weather and cold weather. It happened backing out of my garage onto a sloped driveway, out of a garage onto a flat driveway and in parking lots. The dealer had been unable to replicate it the 2 times I took it in. It happened on a XC40 loaner as well. Last week I needed 10K service, so I asked them to look at it again. They opened a case with Volvo and are replacing a part when it comes in this week or next. I can't remember the part, but will update when I get my car back. Otherwise, I love the Recharge.
