Not sure if this issue is related to the oil change fiasco or not. Maybe someone can chime in, or maybe it's just because it's cold outside (15F to 20F, but I never had issues before). I normally don't go 3200RPM, especially for the first few minutes after the blue thermometer light turns off, so it's tough to say for 100% fact that this just started happening.
Between 3200RPM and 4000RPM, there is a whining noise from the front of the car. Sounded like a tea kettle going off. Got louder as the RPMs neared 4000. This was in CVT mode. The blue thermometer light already turned off, so the engine was warmed up enough to drive. When the engine has been run for 15 minutes or so, when it's fully warmed up, the noise stops, and I cannot replicate this issue. I shut the car down for a few hours, and repeat.
