I have a 2014 C Max and 2 months into the car, ran over something that flattened both my driver side tires and damaged the rims. Rims and tires were replaced and ever since, my ride has been so noisy it drives both my husband and I crazy. We took it back to the dealer and they don't seem to think anything is wrong and the answer was just turn up the music. Unfortunately, not a good answer (nor does it work)! There are 2 different sounds coming from the tires. One is a loud hum that sounds like snow tires. I used to live back east so I know what that sounds like, however I now live in S. CA and we don't need snow tires so I know that's not it. Additionally, quite often I also hear a rattling from the driver's side that sounds like a paper bag is stuck on the car and blowing in the wind. It's really weird and loud. It's not constant but it's enough to drive me batty. I had the dealer check that also and one person said it sounded like bearings, but then when they checked them out, they said they were fine. This car was so quiet when I first got it. Just got home from a week's vacation where I was driving a rental car and when I got back into my car at the airport, the noise was very apparent! Anyone experience any of this or explain what these noises might be?
