PrinzII Posted November 21 Report Share Posted November 21 I have gotten the same recall for my 2018 Edge with a 3.5L V6. Quote Link to comment Share on other sites More sharing options...
Bunky Posted November 22 Report Share Posted November 22 I do not like these kind of recalls in that I would guess engine performance would be reduced. Quote Link to comment Share on other sites More sharing options...
flymore Posted November 23 Report Share Posted November 23 I also got this recall for my 2018 Edge with 3.5L V6. The car just passed emissions test fine, I have no lights or issues and am reluctant to take it in. Quote Link to comment Share on other sites More sharing options...
rafeeki Posted Saturday at 10:18 PM Report Share Posted Saturday at 10:18 PM I see no one has yet reported any problems with the recall fix. I got my notice earlier this week, planning on taking it in, in a few days. Hoping for no issues. Ill post my experience Quote Link to comment Share on other sites More sharing options...
MikeInPA Posted Monday at 04:08 AM Report Share Posted Monday at 04:08 AM (edited) My 2022 Edge just had this recall performed on 12/3. Before the recall, my fuel level was 98% with 343 miles to empty. After the recall, it said 450 miles to empty. Today it's at 64% and 299 miles to go. I'll wait to see what it says after my first fill up. Edited Monday at 04:09 AM by MikeInPA mistyped year of car Quote Link to comment Share on other sites More sharing options...
rafeeki Posted 5 hours ago Report Share Posted 5 hours ago I had my recall 24E09 notice taken care of at the dealership yesterday. There is no change in the vehicles performance. As good as before. Rafeek Quote Link to comment Share on other sites More sharing options...
