I have gotten a "Charging Failure Service Urgent" warning 4 times intermittently over the past 2 months. It always seems to happen about 20 minutes into driving after the car has been sitting overnight and the temperature is around 32 degrees Fahrenheit. The message comes on for a minute or two and then goes off and doesn't happen again for a few weeks. I don't notice any other issues when I see this message. It's a 2012 XC60 AWD 55K. Just wondering if anyone has experienced a similar problem or has any thoughts on what the cause might be.
