[Update] Unable to unlock car, software unresponsive
So it’s been a week since my original post in /r/VolvoEX90. Summary: our week-old CPO 2025 EX90 just… stopped eight days after it was delivered. Handles were out, car wouldn’t unlock, software wouldn’t respond. The App was dead and said “Vehicle offline” or something similar. Volvo Roadside Assistance had it towed to our local dealership, where the service center worked with Volvo USA to attempt to diagnose. They eventually replaced the 12v battery, and we got the car back this past Monday.
On Wednesday of this week, less than 48 hours after getting the car back, the exact same thing happened again.
It’s back at the service center, and while our service advisor has been great, man this is concerning. We’re fortunate that we were at home both times, and that nobody and nothing important was in the car when it died.
The diagnosis process is totally opaque. The service center doesn’t really have more to say than “we’re testing the battery and working with Volvo USA”.
