Edge was in the shop for 16 days. Ford told them to look for a oil leak...they said they found a slight leak from the oil pan, replaced the seal and tested. Exhaust smell was still there. Then Ford said to pull the rear bumper where there are 4 "vents" for release of cabin pressure, such as slamming the door, etc.. Ford sent them four new vents. They thought it was fixed. I took it for a test drive and after several stop light to stop light hard accelerations, smell was still there. They said to take the car and they would contact Ford again. Now just waiting for the next "fix" Ford tells them to do. Not happy!
