NHTSA Complaint #11511040 — 2020 VOLVO XC90

The vehicle shudders randomly when taking off from a stopped position around 18mph. The vehicle shudders randomly when slowing down to make a right turn. The vehicle shudders when driving at higher speeds. It's not a violent shudder, but those riding in the vehicle feel it as well. The safety concern is two fold in that there is a fear of losing control at an inopportune time. Secondly, the constant shuddering over time is going to result in damaging other part of the vehicle, particularly the engine, that will present a safety hazard while driving. The vehicle was purchased used(certified). The dealer replaced collapsed engine mounts on left and right side and considered it resolved. Forman at dealer stated it is common with XC90's to have engine shudder as if this should be accepted. Because the engine shudder is happening at higher speeds now, we're going to return to dealer, but I do not expect a solution. I've seen others report similar issues with shuddering on Volvo forums and I haven't seen 1 solution that worked. This is a problem in a lot of XC90's. The attached documents also contain some attempted fixes to correct a drifting issue.
