Nope, FORD will remain completely silent on this. I’m not letting them touch our vehicle for this reason. It also gives them an out for destroying catalytic converters.

I’m not having it done until Ford can explain all the after recall issues.

Those that had it done report lower MPGs, throwing multiple codes. That’s enough for me to say not to do the recall. The Cat failures are happening regardless of recall.

Wow, Very Interesting FORD has pulled this recall. Curious to see what they do next.

What Model and engine is in your 2018 Edge?

There is another post on this Forum regarding this same exact recall here: Bottom line is that this Recall seems to be creating multiple other adverse issues. 👎

How many miles on your vehicle? How many codes has it ever thrown before? Dang, no reason this warranty fix should be causing MPGs to drop significantly or codes to be suddenly popping up. If anything, MPGs should be improving if the goal is to be lowering emissions!!!!

Agreed. The one thing about these V6 3.5 engines i notice is the CATs are built into the exhaust manifolds which means they are super close to the start of the exhaust coming out of the engine. Not certain but my engineering background means any unburied fuel from a rich condition and carbon is hitting and dumping directly into the CATs. Most exhaust systems I’ve seen in other vehicles the CATs are more downstream of the engine. So maybe this means these CATs and both upstream and downstream Oxygen sensors are more sensitive to slight out of range or rich air/fuel trim mixtures. This layout and setup may mean that it’s more challenging and important for the engine computer to be configured correctly to deal with varying conditions. All this means is that if the system is out of wack slightly on the mappings then the emissions and gases being sent to the CATs will tax it and start coating the precious metals inside the CATs and carbon buildup will occur inside the CATs. Both bad for the CATs.

Wow. This isn’t starting off well!

Yep! The Cats will definitely be affected. “No actual cats were harmed in the production of this post”

Doubt this recall would affect that Mass Air Flow Sensor code, but who knows. A P0420 or a P0430 Catalyst Efficiency code for a bad Catalytic Converter i think would be a likely result of this lack of proper programming since it affects tailpipe emissions.

Yep!!! Please keep us posted on this! Please also keep on them and make them fix the issue. What the service guy said sounds completely false. The fact that the PCM needs to be reprogrammed to lower the emissions means that there are times when too many pollutants are being generated that overwhelms the catalytic converters and they are getting prematurely contaminated and eventually failing. They are prematurely failing due to the PCM programming settings the factory messed up from the get go. IF they refuse to completely fix the issue with replacing new CATs, at a minimum get the service manager to put his words all in writing with his name on the service record. Tell him/her you want them to document this recall "has absolutely no impact on that Engine Light (Should be a P0420 or P0430) on the Catalytic Converters premature degrading/failing. I bet he will refuse to do it, but then say if he won't put it in writing, you'd like your converters replaced since the PCM controls the pollutants that go to the catalytic converters and need to be burned off.

I was wondering why our Catalytic converters are failing in our Edges at relatively low mileages. In my case 139K miles!!!! Now I think we know why after this recall! PCM was likely over richening the fuel to air ratio and damaging the converters over time and leading to higher emissions out the tailpipes. $2500 is a lot of money but if you paid that to replace both catalytic converters and O2 sensors that was fairly inexpensive for that repair. I was quoted over $3500 for replacing both Catalytic converters in our 2018 Edge with a 3.5L. Regardless, FORD screwed up here with the PCM programming and that resulted in the higher emissions and irreversible damage to the catalytic converters. FORD should be covering the converter replacements too. Come on FORD!!!

Have a 2018 Ford Edge Titanium with the 3.5L in our family fleet and received the same recall. Very interested to see if this could have ruined our catalytic converters as our check engine light went on and it could only be resolved with a new Front bank catalytic converter. Shop said both converters were bad and not passing the before and after temperature test, but only replaced the front one as that was the bank the code was triggering. This was after trying to replace both O2 sensors on that bank.
