A high-pitched whine in a Dodge Dakota only when the weather is cold might be a normal thing. When the weather gets cold, the belts, starter and alternator need time to warm up. Try a little drop of dish soap on the fan belt to see if this helps quiet the whining.
There could be many reasons why the Acura makes a high pitch whining noise. It could be that the brakes or the rotors are going out.
