Hey guys. New to the group. Need some advice. Have had my 2017 Ford Edge Sport since august last year. After a month of owning it, i started to hear and feel vibration. It happened when idle at a stop light. You'd feel nothing for 20 seconds and then start to hear a hum which grew louder and louder until the vibration went through the entire cabin. It then would stop instantly before restarting about ten seconds later. Never does it while in drive. Brought it in for service and they couldn't hear it. Unfortunately, it doesn't occur every time you drive the car. The service guys said they couldn't do anything until they heard it. Took it home after two days. It happened again and i brought it back. Same thing. They didn't hear it. Finally, i did a quick search online figuring I couldn't be the only one with this issue. Found some info stating that it could be the engine mounts. When i relayed the info service, they checked them and found it to be the problem. Five months go by, no problems. In the last few weeks, the vibrations have returned. Brought it back to service and even though it is (we think) the same damn thing as months back, they cannot do anything until "they hear it". What do you guys think it is? Is it just bad engine mounts they put in these things? Do they really go bad so fast? Should i take this thing back to the dealer? Any help would be much appreciated.

I'm curious, why would it be engine mounts when tbe engine isn't running? (Assume it wasn't running as you stated "restarted"). One thing that can cause periodic vibration at "idle", engine running or not, are the radiator cooling fans. If a blade is unbalanced, you could hear a hum and feel the vibration. (It's been My experience with bad mounts, they get worse when driving, depending on engine load). It's not normal for them to fail, I had a set replaced on a car years ago and they were horrible. The mechanic used NAPA ans I made him replace with OEM. All problems went away. So one question you could ask is, did they use Motorcraft or aftermarket?

Hi Mr. FordTough,  glad to have come across your post.   I have a 2018 Ford Edge SPORT with only 6,000 miles and I have similar issue (if not the same).   I have played around and experimented alot to narrow down what it is, and what it is NOT.    

ISSUE:    There is a vibration that starts off very low and builds up and definitely audible and strong at the 15 or 20 second mark,  and then it dies completely after 20 seconds every time.   I timed it with stopwatch.   After the vibration ends (after approx 20 seconds), it starts building up slowly again, becomes very noticeable after 15 seconds, strong for the next few seconds, and again, dies after 20 seconds, repeats over and over.     

 

Here are my observations with the vibration issue:   

1. (IMPORTANT)  The vibration seems to only happen when there is some weight/load in the rear cargo area and drive around a  little with the weight in the back.     

    If I remove the weight/load  (some tools and some emergency iteams that I carry around)  from cargo area,  the vibration eventually dissipates (takes several minutes or hours but dissipates eventually).    If I put the weight back on in the cargo section,  the vibration returns, it may take a few minutes or hours.

 

2.   The strong vibration only occurs when I've stopped at Stop Sign or Red Light,  and goes away when I start accelerating or the car is moving.

       Also:   If the suv is carrying some weight,  and the vibration is occuring,   the issue dissipates if the car is sitting for a while (engine running, park for 15-30 minutes).    The issue returns after you start driving around again.    

 

3.   I've ruled out that it is NOT the AC,  it is NOT the tires in any way, not the stereo/speakers, it is not the wheels itself (they are aired correctly and balanced, double checked).

 

I've tried recording the sound but unable to capture the vibration+sound  that well on my phone.   Luckily,  a few days ago,  I drove into a nearby dealership when the issue was occuring and the  senior tech did some poking around and was perplexed what this could be.   He has never seen this before.     The part that doesn't make sense is that it cycles every 20 seconds.     What system or component causes the 20 second cycling.   is the big question.      I'll be turning the car to have this issue looked at as soon as they have a loaner available.    The tech thinks this may take a couple weeks to figure out.           If this does not get resolved, I am left with no choice but to dump this car, as the vibration is unbearable.   It has a strange .. frequency, harmonic?   that is frustrating to have to listen to,  (like nails on chaulk board effect)..      I'm sad because I may have to walk away from the FORD brand.     Does not seem right to lose money twice by buying another product from same manufacturer (unless they offer some sort of buyback or something along those lines)

I have the exact same problem!  My 2018 Edge Sport has been to the dealer 5 times now.  Ford Customer Service is now involved.  The problem is the Active Noise Control.  They've tried replacing the microphones in the head liner, the radio head unit, and a control module in the rear of the vehicle.  Nothing has resolved it yet.  However, the noise / vibration is a little more steady now instead of cyclic.  As with your Edge, it only happens during idle and it's worse when the cargo area is full of stuff.  However, I have noticed mine seems to happen when it's warm outside (above 70 F).  It may be a coincidence, but my problem started around Aug/Sep 2018.   I took the Edge in for repair in Oct 2018 and they couldn't find the problem.  It wouldn't make the noise.  It didn't happen once during the winter months.  Then in March 2019 when it started getting warmer outside, it came back.  I began to notice that it wouldn't do it in the morning, but when I got in the car in the afternoon (after the Edge sat in the sun all day) it would do it.  Now that it's summer, it does it every day, and any time of day.  Ford technical specialists are now involved, but they have not came up with a solution yet.

 

Update 8/2/2019:   This is how I’m convinced it’s the Active Noise Control software through the stereo.  I read that other Ford cars have the same problem (vibration noise at idle) and as soon as you open the door it deactivates the software. So, while my Edge was making the noise/vibration I opened the the rear lift gate and it stopped immediately.  Within 10 seconds of closing the lift gate it started again.  This time I opened the driver door. Same  thing; it immediately stopped.  Tried this sequence several times with the same result. Also, if you roll down the windows or open the sunroof, it won’t stop. You have to open a door. 

Hope this helps other’s troubleshoot.  I’ll post the finding’s from Ford after they work on it again.

Helloooo, just got my 2018 Edge Sport back from dealer yesterday after 3 weeks of investigation.   You're right, it's the active noise cancellation system/module.   They gave me the car back (their choice) while Ford engineers investigate.  Lets keep in touch on this forum...   if this does not get resolved in next few months,  we may have to escalate together.    If I hear anything, I'll post, and please do same if you hear anything on your end.     Thanks.

Mine is scheduled for the Ford regional engineer to take a look at it next Tue. 8/20. I’ll let you know what they say. I think they have a software problem.
