I promised I would report back when I took my TCH in for the oil change and described the increased whine to the tech.

You guys can probably guess the outcome. The tech said that the noise was normal and wasn't any louder than other cars. I didn't have a chance to compare with any other cars so I guess I'll just live with it. At least it has been recorded as a complaint in case something does go wrong.

On the positive side I got some 5W20 oil, tires rotated, they turned off the DRL's (free of charge), AND they fixed the cricket noises in the center console. Not a bad day I would say.
