Lift gate opens automatically, get about half way open then closes. Sounds like its a sensor. GMC 2007 Yukon Denali - can I repair this or do I need to take it into repair shop.

It is quite possibly just a weak support strut. Look for leakage on either of the struts. The lift system requires the assistance from the struts to complete an opening. The excess weight of the door, without the assistance of the struts, causes false reversal.
