This vehicle has a recall 21E11, for an inlet exhaust leak on the driver side, but the service technician when doing the recall says I have the exact same thing on the passenger side - a weld has corroded and there is an exhaust leak (photo available). The passenger side is not covered by the 21E11 recall, but is the same identical weld/corrosion/exhaust leak issue. They quoted $3,500 to repair. I have escalated via Ford - case number CAS36437910, but until this side has an official recall, they won't repair.

When using the defrost or air conditioner or just having the fan on, exhaust fumes enter the cars cabin. Its very troublesome that when I took it to a Ford dealer and they checked it out and said the catalytic converter was cracked but told us Ford had no fix for it. Its very dangerous especially in the morning time when you need to use the defrost you have roll all the windows down and freeze you butt off.
