We have a 2019 T8, it has 4K miles, noticed oscillating on the interstate while in autopilot. It got progressively worse over the follow days to the point the car was difficult to control. We took it in for troubleshooting, technician found one of the bolts connecting the right rear lower control arm to the knuckle had nearly backed completely out, bushing was dislodged. Evidently there is a service bulletin for this issue. This could cause a serious accident, want all you guys to know this problem is out there, and Volvo knows!
