Hello everyone,
I have a 2015 Volvo S60 T5 Premier. I've only had it for about 4 months. The warranty expired on the 28th of April. I started having problems with it this past Wednesday. When I press the accelator I hear a sound as if I was driving on a flat. I googled it and it said a bubble or a knot was on the tire. I got that checked out. That wasn't it. I tried to clean the rocks out of the groove of the tire since I know the rocks can make sounds from previous experience with my Mazda. Noise is still happening. The car is also shaking a little bit. Has anyone figured out what the problem was. I really like my car but the issues not so much.

 

Have you stopped by a dealer? many will offer some good will if you explain the problem started when the car was in the warranty period. Car probably needs a good inspection - can be one of several things - something caught up in a wheel, a tire issue (try a front/rear rotation to see if that changes anything), see if the vibration changes with braking pressure etc, a suspension issues, something with the axle/boot.
