Based upon what you have said in your question, I would say that it would probably warrant a consultation and perhaps a review by a medical expert.

A placental abruption is a true emergency, and the length of time from the abruption to the delivery is almost certainly a factor that plays into the ultimate injury to your son. Autism may or may not be related to this insult, but I would want to have a qualified neurologist examine him to make sure of that diagnosis.
Also, I would want to know more about the symptoms that your wife informed her ob/gyn about in the 3rd trimester.
