      Logic? Okay. I’ll explain it all out. Slowly. The rotten egg smell comes from an excess of unburnt fuel. Combustion, all of it, produces CO. If you can smell the unburnt fuel in the car, there are exhaust gasses in the cabin. Back to the fact that all combustion products CO, and you can smell excess unburnt fuel in the cabin ........ there WILL be CO in the cabin as well.

      As for your snarky comments on the exhausts, there have been reports of CRACKED manifolds. A brand new, entirely unrusted manifold can crack. And, of course, Ford Has had manifolds crack and fail before.

      I don't believe that any one has mentioned that the leaks are from the exhaust system itself. In some cases the exhaust tips are being changed to direct exhaust downward. I believe all the items Ford is addressing is contained in various posts/threads here.
      And as Mbrooks420 mentioned, the fact that you have exhaust entering the cabin you will also have a certain amount of CO.

      I think the exhaust issues are specific to the PIU’s.

      The cracked manifolds were related to the 3.7 in the PIU so you are correct, not the 3.5s.

      The cracked manifolds haven’t been an issue with the 3.5s.

      Got notice today. Leaving on a 3000 mile trip on Monday morning. Have only put 3k miles on this vehicle since purchase and NO extended highway trips. Will have 4 passengers, guess we will keep windows cracked a bit, and maybe have service when back. Can't tell the wife, she would freak and cancel the trip....this sucks.

      It’s probably nothing to worry about. If you are concerned throw a CO meter in the car for piece of mind.

      I got the letter for 2 voluntary checks up: Exhaust issue and front door panel separation. I took the Explorer to Ford Dealership 2 weeks ago and they checked it. Said no exhaust issue with my Explorer and fixed that door panel. I even asked them to check MyFord touch and they found wires loose and fixed that. Now I can use MyFord without any issues.

      Bigtexan99, curious to hear how it went. I too have a '16 Sport and got the letter the other day.

      Does anyone know the dealer procedure to do the fixes? Do they have to take the rear bumper cover off?

      Chartquist, the Sport has had the CO fix applied yesterday, but I don't get the car back till next Wed as they found other stuff to do to it. Will post up when I drive it.

      My vehicle is at the local Ford dealer today for multipoint inspection, oil change, tire rotation and the 17N03 exhaust gas/carbon monoxide repair, I will report back to this forum soon with an update.

      Picked up my 2014 Limited today after dealer performed the 17N03 Field Service Action. Reprogrammed the HVAC module, sealed any holes, ports on underside and back of vehicle. Initial test seems to have solved the problem. More info to follow.

      Took the Explorer down to Phoenix over the weekend with some hard acceleration, coming back up the mountain to Prescott, no evidence of the smell I've had in the past.

      That's great news TB! I saw a tech doing the repair today (not on mine) and got to handle the original louvered air flaps that are on the side of the car underneath the bumper clip. Those things are flimsy! It's no wonder they were possibly letting air back in. The new drain flaps on the underside edge of the liftgate are also much more solid. I think my Sport will be ready end of day tomorrow or Wednesday so I'll have my update soon.

      Does someone who has had the fix done, and the HVAC reprogram applied know if the car automatically switches back to RECIRC after it has been opened by the reprogrammed operating conditions of do you manually have to push the RECIRC button yourself to close it?

      I’m sure it reverts itself, or everyone would be salty.

      Had a great trip, and the Explorer performed flawlessly, except that the gas mileage wasn't all that great. Admittedly most of the driving was done at 75 to 80 MPH or better, and in the mountains sometimes as well. The trip totaled 2700 miles, and the computer shows 17.9 mpg. Probably would have achieved 18 except that on the way home, and needing some rest, the car ran with the heat on for about 3 hours during naptime (with windows cracked, of course). The only noticeable exhaust odors were diesel smells which did come through the a/c system, but that is nothing new. Still going to take the car in for the service, but am much less worried than before.
