While driving, a sudden onset of dangerously strong smelling vapor / fumes expelled through the ventilation system causing adverse reaction to driver and passengers. Happens while heat is on, but does not happen when air conditioning is used.
When the speed of the car starts to reach 50 miles a high pitch sound occurs. I cannot determined if it is related to when air conditioner is turned on. The noise will diminish when speed is lowered to about 45 miles. I cannot recall if this happens in the colder months but it does seem to happen in the summer.
