    Peter: I will use my carbon monoxide data logger to see if CO goes away after I install this SSI tune.
    Mbrooks420: In the SSI forum, it shows the second part of the tune is selecting octane to use, so I will select the 87 octane.
    I will do another 6 months of testing once I get things set up, and report back.

    I'd like to let everyone know I put 9k miles on an 18' XLT after trading in my 14' Interceptor SUV...................I still get an exhaust smell on heavy accel. As it's also going in for an oil leak, this will also be part of the diagnosis.

    Ford is flying engineers to the dealership this week to inspect my '18. I'll keep you posted.

    Update, see attached letter from Ford after and Engineer was flown out to inspect my 2018 with 10k miles on it. Vehicle was driven about 40 minutes for the testing.

    Hey there. I got the exhaust replaced with the revised downward tips but the smell is still there. Not sure what to do at this point.

    What are you actually smelling?
    Exhaust fumes or rotten eggs?

    It’s an odd strong smell. It’s definitely exhaust fumes but I could see why some would say rotten eggs. It’s mostly noticeable about 30 seconds after accelerating hard.

    Yeah, that's not acceptable and frustrating.

    Hi. Can you tell me exactly which SSI tune kit you got? And do you now have to use higher octane fuel?

    A tune is good for performance reasons, but will NOT fix this issue.

    So, lately my Explorer's had more issues with exhaust smells.

    Last week during the frigid weather, I cold started it in 0F and it stayed at high idle for a good amount of time during the remote start cycle. When entering the cabin it smelled like burning brakes--but when the car was switched ON fully and the HVAC strategy changed a bit, it went away quite quickly. For those keeping score, it couldn't have been brakes, the car hadn't moved for 12+ hours during the start cycle.

    I'm also getting a little smell like this on hard accels again, but not enough to have posted about alone. Thoughts?

    Our weather is mild compared to yours but since the PTU was replaced last month I've done a few WOT's and each time I get the exhaust smell within a few seconds. This car usually has the HVAC set at a certain temp and is rarely in the Off setting.
    It's had the CO/exhaust fix done at the Dealer.
    I wonder if the 2020's will have this problem.

    I don't think so. I believe this is a design flaw that Ford just can't fix permanently on the 5th gen. I believe it comes down to aerodynamics mostly. I'd bet just about anything that Ford focused on this greatly when redesigning for the 6th gen.

    How would Ford focus on exhaust odor in the cabin problem when they acknowledge that it is not a problem to begin with? Ford has not issued a recall and have not fixed the problem for 9 years. I have provided information to define the problem and propose possible solutions to Ford, and received zero response/feedback from Ford; that is not a company that is focused at all. Based on these facts, I just do not see your leap of faith in Ford fixing this problem.

    Just because they don’t publically acknowledge there’s an issue doesn’t mean they don’t know it exists.

    There’s liability in admission. They can’t recall it because they have no definitive fix. A company like Ford would never open a dialog about a design shortcoming with an ordinary person.

    I’m pretty sure they know exactly why it happens, and there just isn’t a way to fix it.

    They don't acknowledge there is an issue? The fact that they have issued several TSBs on this issue (at least 3) and have designed modified exhaust systems, vents, seals shows they acknowledge it. What they are NOT acknowledging is that it is a safety issue. Recalls are issued for safety, not for design.

    So yes, they attempted to fix many times BUT will not recall. So again, I do believe Ford focused on this issue and it will not happen again being this is a ground up redesign.

    Yeah, I've got to keep going with @blwnsmoke on this one.

    I won't speculate on the engineering other than to say that the "true" fix is probably way, way too expensive to pull off. Hence, you get a solution that fixes a significant part of the problem, but not all of it.

    Unfortunately, the game is "how much can you get away with," and that's not to speculate maliciousness on Ford's part as much as recognizing that life is a series of trade-offs. And every human and company will perform that analysis.

    In my case the problem has been especially intermittent--I wonder if it's my fuel quality that's at the root of this, not that it gives me any comfort that "good" fuel wouldn't smell into the cabin. But I'm not an engineer, I'm not getting ill, and my CO detector thingy hasn't triggered either.

    I had this issue on my 2012, I don't on my 2018. Strange.

    For some reason, not all Explorers seem to have the issue. No issues with my 2011 or 2017.

    Same, my colleage who now owns my 2016 Sport, hasn't complained about excessive exhaust smell, other than the rotten egg when he goes WOT.
