Hi, When you drive over 70mph, steering, floors and whole cabin start vibrates, I have changed tires as Volvo recommended, alignment done. Everything dealer requested I have done. I have driven couple of more volvo as a loaners and noticed they all vibrates , but not bad as mine. Try to reach out Volvo head office but no proper resolution. They are keep blaming tires which I have changed 3 times but actually vibration happen from engine or somewhere else. Lots of Volvo owners online shares same issues online. Please help me out on this matter.

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 2018 Volvo S90 T6 verdict →
