Gas Recirculation Valve (egr Valve) problems of the 2012 Subaru Legacy

Purchased brand new Subaru Legacy October 31st of 2011. After only five months and 14,000 miles beginning in March of 2012 I was shocked to discover the following problem(s) with my Legacy: low idling, bogging down, at oil light illuminated, and nearly stalling out. This issue is still continuing to this day, sporadically. I now have 25,500 miles and there is no solution to this problem. I experienced this low idle, bogging down, and nearly stalling out- at the following documented mileages: 14,989 miles, 15,120 miles,17,007 miles, 17,714 miles, 18,124 miles I then began a more detailed log: 18,383 miles, April 19th 2012, 3:23 p. M. , 74 degrees. 20,074 miles, may 2nd 2012, 12:37 p. M. , 78 degrees, and 80 miles driven that moment. 21,558 miles, may 16th 2012, 10:06 a.
