The brakes did not work when the automatic emergency braking turned on. When I pressed the brakes all the way down, the brakes didn’t respond because it was still in automatic mode. I was able to swerve into the next lane to not hit the vehicle in front of me. The automatic emergency braking also turned on when I was reversing from a parked location when there was a vehicle waiting to park behind me and my vehicle stoped and didn’t come off of brake/park mode. I had to turn my vehicle on and off again to get it to move again. I have taken my vehicle in twice for shaking. My back rotors were replaced 2 weeks ago but my vehicle still shakes. This car only has around 21,000 miles to have so many issues already with rotors and shaking.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Volvo XC90 T6 verdict →
