I drive a 2008 Solara. Two weeks ago it developed a cabin noise that is best described as a low pitch, whirring noise. For those of you who remember the old snow tires, it kind of sounds like that. Here's the interesting part. The noise revs with the engine, yet you can't hear the noise outside of the cabin. The car was at the Toyota dealers yesterday for routine maintenance and they could not identify the source of the noise. Has anyone experienced this situation?
