I have a 2014 Chevrolet Cruz with turbo. When I'm driving in regular drive it is making a noise like I'm driving in a lower gear. I can hear the noise over my radio its so loud. I took it to Chevrolet mechanic.. He said it was my tires running on the road making the noise.I don't think it is.I think its something wrong with the engine. I'm trying to identify the noise or problem.
