MPW Posted January 19, 2015 Report Share Posted January 19, 2015 Hello,First of all, I hope this would be the right sub-forum. I didn't know whether to post it here or in 3.5LNew owner of a 2012 Limited AWD.When decelerating, it seems like it is actually braking. At first I thought it was something to do with the collision avoidance system or something, but my brake lights aren't coming on. And I've tried it with all of the BLIS system turned off. Same results. Let's say that I'm traveling down a 55mph road and I can sense that a stop-n-go light is going to change from green to red. Being a closet hyper-miler, I will kick off the cruise way before the light even changes so I can just coast and hopefully not have to brake hard. The thing is, coming out of a Pontiac Bonneville that would coast for hundreds of yards even while in gear, the Edge seems to REALLY decelerate quickly as soon as you've removed your foot from the throttle. I'm not talking throw you through the windshield or anything, but I end up having to get back on the throttle just to make it to the stop-light. So, of course being paranoid, I checked to make sure that it freewheels OK while it's not in gear to eliminate the possibility of a hung brake caliper. There's a road by my house that has just enough slope to it that if you let off the brake, while in neutral, you will very, very slowly start rolling. The Edge rolls fine on this hill. Any thoughts?

akirby Posted January 19, 2015 Report Share Posted January 19, 2015 It's normal. DFSO is deceleration fuel shut off and it cuts engine power to save fuel while coasting. My Fusion does the same thing. Check your tire pressure. Low tire pressure will make it worse. Try adding 2-3 psi above the mfr recommendation - seems to help a little.

akirby Posted January 19, 2015 Report Share Posted January 19, 2015 It will also do it more aggressively if you're coasting and tap the brakes. This helps to maintain speed when going down long hills. 1 Quote Link to comment Share on other sites More sharing options...
MPW Posted January 19, 2015 Author Report Share Posted January 19, 2015 Thanks akirby, that seems legit. Was just a little shocking coming out of a luxo-barge with the Cadillac drivetrain (GXP) Mike Quote Link to comment Share on other sites More sharing options...

ls973800 Posted January 21, 2015 Report Share Posted January 21, 2015 I remembered when I bought my 2013 Edge new and test drove it. I was coming out of a 2003 F150 that I drove for over 10 years. The first thing I noticed on the test drive was the "drag" when I was slowing down and wasn't touching the brake at all. It was so noticeable that I even pulled over and checked the parking brake just to make sure that wasn't partially engaged! The salesman said it was because of the car having 20" tires and that they caused the rolling resistance. I did some checking around before committing to an Edge because of that drag, and found it to be normal, and for the reasons stated in previous posts. I purchased that Edge I test drove and after a few months got used to the way it drove. I now have 40000 miles on that car and don't even notice it. 1 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted January 21, 2015 Report Share Posted January 21, 2015 How's the response when you get on it after a period of "no-touch" on the throttle? Any noticeable lag? Quote Link to comment Share on other sites More sharing options...
akirby Posted January 21, 2015 Report Share Posted January 21, 2015 Nothing to add - just wanted to say thank you for spelling "braking" correctly........ Quote Link to comment Share on other sites More sharing options...

If you are asking me, I have never had any lag or stumble if I accelerate hard while the car is in the coasting mode. 1 Quote Link to comment Share on other sites More sharing options...
MPW Posted January 22, 2015 Author Report Share Posted January 22, 2015 Nothing to add - just wanted to say thank you for spelling "braking" correctly........ Lol, best thing I've read today! Thank the government and CAFE for that one. I don't have anything to thank them for. Bunch of "Chicken Little" biscuit lickers! How's the response when you get on it after a period of "no-touch" on the throttle? Any noticeable lag? No lag that I've noticed. This whole "let's save the planet" thing should be something that can be disabled by competent drivers. For years, I've been conscious of my surroundings and the activity taking place in front of my vehicle. For example, on approach to my house, from 55mph (I live on a country road), there is enough of a slope in the road that I used to be able to coast my Pontiac Bonneville, while in gear for about a half mile, and still be at 30 mph by the time I had to brake for my driveway. With the Edge, I have to maintain power all the way until about 500 feet from the house. Now Cafe, CARB, or whoever the heck you are...tell me how that's more efficient? <\Rant> Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted January 22, 2015 Report Share Posted January 22, 2015 A tune might help out in this case. I don't think there's a hidden menu anywhere that will "revert" behavior back to the "olden" days. Quote Link to comment Share on other sites More sharing options...
allport Posted January 24, 2015 Report Share Posted January 24, 2015 My old ford focus even did the same thing. I actually tuned it to do this more aggressively. However on the focus the cut in for this mode was around 30km/h or so i upped it to 80km/h. The only difference i saw was better gas mileage and no loss of performance or driveability. 1 Quote Link to comment Share on other sites More sharing options...
