NHTSA Complaint #10704058 — 2011 SUBARU OUTBACK

I PURCHASED MY 2011 SUBARU OUTBACK NEW AND LOVE THE CAR. HOWEVER IT HAS ONE PROBLEM WHICH HAS SHAKEN MY CONFIDENCE IN IT. WITH THE VEHICLE IN DRIVE, MY FOOT ON THE BRAKE, AND AT A COMPLETE STOP, THE ENGINE WILL SHUDDER VIOLENTLY. THE RPM'S WILL LOOSE ABOUT 200 TO 300 RPM'S, THEN GO IMMEDIATELY GO BACK UP TO THE CORRECT RPSM; THE ENGINE WILL NOT DIE BUT FEELS AS IF IT MIGHT. THIS HAS HAPPENED MANY, MANY TIMES. IT DOES NOT SEEM TO MATTER IF THE ENGINE IS COLD OR WARM, IF THE A/C IS ON OR OFF, OF THE RADIO IS ON OR OFF, OR ANYTHING ELSE. I FULLY EXPLAINED THE SITUATION TO THE DEALER WHEN I TOOK IT IN FOR AN OIL CHANGE. I TOLD THEM I CAN SOMEWHAT REPLICATE THE PROBLEM BY PUSHING THE DOOR LOCK/UNLOCK BUTTON WHEN THE CAR IS AT A COMPLETE STOP, IN DRIVE,WITH MY FOOT ON THE BREAK; IT IS NOT AS VIOLENT A SHUDDER BUT VERY SIMILAR. THEY KEPT THE CAR OVERNIGHT AND SAID THEY TEST DROVE THE CAR BUT "COULD NOT DUPLICATE" THE PROBLEM. IT APPEARS THIS MUST BE SOME TYPE OF ELECTRICAL CONDITION. I AM DREADING THE DAY WHEN I AM ON A BUSY SOUTHERN CALIFORNIA FREEWAY IN STOP AND GO TRAFFIC AND THE CAR LEAVES ME STRANDED. ANY SUGGESTIONS? *TR
