I'm thinking about purchasing a AWD/Ecoboost but am concerned about conflicting owner's reports about fuel effeciency. Some Edge drivers claim 24-25 Hwy while others get far less. I presently drive an 02 Jeep Liberty and its best Hwy is about 21. I just got to do better than the latter. Amy comments out there?

I have a 2011 Edge awd v6 and an Explored Ecoboost with 2,600 miles. Road tests on both report that the payback for the Ecoboost (a $995 option) is about 3 years. On recent 1,500 mile trips my Edge got ~23 mpg (summer gas) while the Explorer got ~25 mpg (winter gas). The Explorer is larger and heavier than the Edge, so an Ecoboost Edge should do at least as well. Both engines are excellent, but a couple of mpg and longer range are a free bonus if you keep your vehicle 3 or more years. The real question is if you can live without all wheel drive. If you can, test drive an Ecoboost!

There are quite a few nice changes to the 2012 that made me wait.

Changes? Other than the 2.0 Ecoboost could you list them or provide a link?

Yep and I've never seen any scratches in my paint in the sun. I'm not saying they aren't there, but they're certainly not visible to the casual observer.

 

I think the cloth strip type automatic car washes are relatively safe and a reasonable alternative to hand washing for most consumers.

I agree. In April my '08 Limited was at the body shop for a door ding. I asked about the car wash. They said my paint was excellent. The Edge rarely missed a week at the cloth strip car wash.

Choff:

 

Your issue is wind "buffeting" due to quick pressure changes back and forth due to flow variation. Not many vehicles deal with this very well.

 

 

OP:

 

Most vents for cars are located in the trunk area. If they are closed, or blocked, pressure can build. I crack the BAMR if I get uncomfortable (not often). Look at the vents in the trunk compartment and see if you can make them flow better. Usually, they have a flap to block things from entering the cabin (spiders come to mind).

Thanks! I'll look!

When the climate control on my '11 Edge is on the pressure in the cabin builds quickly. It is irritating and sometimes hurts my ears and causes a minor drum like rumble. Cracking a window stops the problem but is noisy. Does the cabin vent? Where? Would it be feasible to open or make a vent? My '08 Edge did not have this problem.

Could be a bunch of things, but it sounds like a single build/manufacturing issue, not a design issue. Boom issues can be cause by roof bows not bonded, liftgate fit, ground out subframe mounts or just about any sealer skip/ missing weld in the body.

 

But based on the conditions you describe, it sure sounds like either a bad motor mount or a ground-out in the exhaust somewhere. Does your dealer know how to neutralize engine mounts?

UPDATE... Dealer can not find a problem but acknowledges the noise. I'm going to try another dealer. I did find a way to reduce the noise; that is, put the climate control in recirculate or crack a window. The high pressure caused by the fan definitely hurts the ears and amplifies the rumble. I'll do a separate past on that matter.

Great suggestion! I called my dealer. They will check the motor mount and exhaust on the 25th. I'll post the result. Thank you!

<br><br>Does this sound occur with the car parked and running?<br><br>I would LOVE to hear some audio or a video if possible.

 

<div><br></div><div>EDIT: I just re-read the original post and thought of something. When parking my car, I can sometimes hear the gas slosh around in the tank quite a bit. And it does sound like a rumble sometimes depending on how smooth I am with the car. Any abruptness and I can almost feel the momentum of the gas. Maybe something is in contact with the tank, sending the sound to the chassis.</div>

Interesting...my wife hears the sloshing in the tank as you describe it. The dealer did remove, check and re-install the tank, buy maybe there is a ground-out there?

dont try to mask the existing problem. just keep at it until you find it.

You are 100% right! Any other Ideas as to the cause?

Final update. Given the lack of response to my post, I assume this is a rare issue. Removing the subwoofer and force balancing the tires did nothing. The dealer swapped the 18" Michelins for 18" Continentals. The tire swap seemed better initially. When the tires warmed up the noise was the same. And there is still a loud booming sound (like a kettle drum) when hitting some bumps. on undulating pavement and at low speed when the engine is at low rpms and the ac kicks in or the shifter is moved in and out of drive. The car goes to the dealer today, I have asked Ford to replace it.. I loved my '08. and my brother's '11. My '11 is loud and irritating. I hate driving it!!

UPDATE!! Tried adding 36 square feet of Dynamat Extreme. The Edge is quieter but the rumble...at idle and over undulating pavement. remains. Curiously, the exhaust note outside of the car is the same frequency. I think there is some large panel which is picking up the sound. My brother's '11 has the same exhaust note but no boom and rumble. The dealer is trying to get a Ford engineer to help. I loved my '08 Edge. The '11 is so loud that I will no longer drive it. If it can't be fixed I'll dump it asap. It's not just the noise but an irritating penetrating boom. For $39.000. it sounds like an empty panel van. 10 days in the shop and no progress. AND YES the Ford mechanic hears it too, ANY HELP! This can't be the only loud Edge!

Any help appreciated. My friends won't ride in the car. The rumble is that irritating!

OK MY BAD I WORDED IT WRONG. Thanks for always going above and beyond to point out any mistakes Anybody makes, we are not all perfect!

 

The Ford Dealers!

 

With out the Ford dealers Ford makes nothing so in turn Ford does make money because the Dealers buy the keys from Ford also. The Dealers close up and Ford Motor Company shuts down, either way Ford is making some profit of the programming even though it is a key sale.

My dealer has never charged for key programming...including my after-market flip key. It takes 2 minutes!

Dynamite is a waste of money. In all of my previous cars I've used a product called quiet car. Www.quietcar.net. Fantastic spray on visco elastic that takes vibration energy (noise) and turns it into low level heat. I've used this with great success. It's worth buying the gun and using a compressor. When I sprayed this into my 2005 Escape, it was quieter than my dads Lexus RX300. Plus the weight in dynamite that you would need to equal the noise canceling of this stuff is beyond compare. Read up on it, try it, you won't be disappointed.

Dynamat is expensive. I'll look into Quiet car

If it seems just like the same noise but louder do you think maybe it could be something as simple as missing insulation somewhere?

My guess is that you are right. I assumed my dealer checked that. It's been in 7 days trying to find the cause. My car was built around the time Ford modified the roof structure in February. I wonder if they missed something on my car during the transition. Tapping the roof does not reveal any unusual sound.

Missing grommets usually result in high frequency noise, low frequency is more likely a ground out. I'd focus on neutralizing the engine mounts and subframe.

Thanks. Very helpful and not that hard to check. From day one my brother questioned the engine mount/subframe. He has an '11 Edge SEL which is very quiet.

Could be any one of a million things, but it's probably just one thing. Could be as simple as a missing grommet or plug somewhere. Could be a ground out in the exhaust. Could be a leak in the exhaust. Have they tried neutralizing the engine mounts and subframe? Could be that some part like a dash insulator, baffle or something was "missed".

 

Dynamat isn't going to do anything for you. Usually when you have an error state like this, you can't mask it. It's kind of like a leaky pipe. You might have a hundred joints that are perfect, but if just one of them is bad, you're still getting wet.

Thanks for your thoughts . Makes sense. The dealer is willing to keep looking and would install the Dynamat . They agree my car is unusually loud. What is odd is that it is only a particular low frequency that is loud. It is otherwise quiet! I will look for a missing plug or grommet.

This issue is going to eat away at you and piss you off everytime you even think about driving. The noise will get louder....at least in your mind, and will end up absolutely hating an otherwise great vehicle. If you have the financial means to take a loss on trading it in on another '11......do it. Ford and your dealer will do absolutely nothing in terms of a replacement vehicle at no cost due to the issues you are having. If you have a good dealer, they may offer free routine maintenance for 5 years or free extended warranty after you take the hit. They are under no obligation to do these things but it would be nice.

I appreciate your response. Your thoughts echo the advice I got from a retired zone rep. Has anyone had experience with Dynamat? For $200 - $300 I could have a car audio place dampen the doors and floors. If my problem is general loudness will this make a noticeable difference? any advice is appreciated.

After driving my brother's '11 Edge and every '11 Edge on the dealer's lot, it is clear that my '11 is much louder. It is also much louder than my '08 Edge. My former post complained of a rumble or harmonic, But after driving these other cars I note they produce the same sounds just at much lower and acceptable levels. It's not wind or road noise but low frequency engine, drivetrain and suspension noise. Luckily the dealer can hear it too. They have tried many fixes: remove and rebuild the fuel tank, replaced the tires with a different brand (helped suspension noise a little..did not affect other sources), Swapped 20" wheel/tire (Similar result as different tire), removed the subwoofer (possible harmonic...no help), removed spare tire, checked interior and exterior panels, heat shields, etc. Nothing works. They are calling the rep for help. WHY IS MY EDGE LOUDER THAT YOURS?

No luck on eliminating what I now know is a harmonic noise. I will not drive the car! My wife is not sensitive to the frequency so she doesn't care. She is disappointed that our '11 Edge is louder than the '08 we traded in. The dealer will be trying again next week. Frankly, I don't want it back. My brother (who is an audiophile) is convinced that the subwoofer is defective and is passively radiating a harmonic. He has a '11 Edge without the subwoofer but with the same tires. His car is much quieter than mine. The dealer did not agree but will pull the sub next week. Help!?

Update! The dealer swapped 20' wheel/ tires for my 18"s. Sound was 95% gone! Still a slight harmonic rumble that last second before stopping or when placing in park or from park to drive. The "boom" with the 18"s is present on undulating pavement...so its not bumps but change in rate of movement that results in the harmonic rumble or boom. The dealer is reluctant to check the motor mounts...saying there would be other signs of a bad motor mount. Did not remove the subwoofer (to see if it is passively delivering a harmonic}. The dealer wants to try a "force balance" of my tires. The fact that no one else has experience this is not good news in trying to find the cause. I appreciate all suggestions!

Thanks for your suggestions. The dealer carefully checked the exhaust system, removed and rebuilt the gas tank, checked all heat shields, checked interior trim, and inspected wheels and spare. I am surprised that others have not noticed this. The harmonic boom is very grating and loud. I am now sensitized to it. A retired Ford zone official had some good horror stories about harmonic problems...including a Pinto wagon fixed with a ball peen hammer. The car is much louder than my identical 2008 Edge. ALL ideas are welcome!

Hi mgmgrand, I have the same question about these bulbs. I did some research about Philips 3rd Gen HIR2 bulbs and they seem very good, from what I've read. But I'm concerned about the high/low beams. Does the HIR2 from Philips have a dual filament? Still can't find that out. Didn't want to loose my high beam abilities. I'll keep you posted on my research progress.

 

Damon

Does not need a dual filament. A shutter in the headlight assembly opens for high beam.

Did anyone check the spare tire? Loose?

 

 

 

Not sure if I am missing something here-a brand new car and it would need to have different wheels/tires put on to eliminate this loud annoying noise? I re-read the thread to see if aftermarket wheels were put on but not seeing that. Is this an issue with the 2011's at all?

I just bought a 2011 edge sport 2 weeks ago. I was wondering how exactly the high/low beams work since it is in a projector type housing. When you cycle to high beam and back to low it sounds like something clicks or moves within the housing. Is it something moving so that the beam of light raises up? Anyone know how exaclty they have it set up ? Also i have not taken the bulb out but is it a dual filiment like a normal high/low beam bulb? Thanks in advance for any info.

There is a semi-circular shield which pivots out of the way for high beam. That is the noise you hear. The bulb does not move.

Have the dealer swap on some dubs from another car and test it out. Also test your 18s on the other car.

Good idea! When I called the dealer they were very happy to try. The mechanic had suggested this as an option. If the problem is harmonic a different wheel & tire should reduce or eliminate the noise.

Just got a 2011 Edge Ltd AWD. It replaced a 2008. It is a nicer car with one very troubling noise. When driven at low speed, the slightest pavement irregularity results in a low frequency boom. A kind of rumbling sound. The booming also occurs when stopping on smooth .pavement. It can be heard on the highway but is drowned out by road noise. My wife thinks it is from the gas tank She thinks the gas level affects the volume of sound. The exhaust and suspension mounts all look good. Rapping the gas tanks results in a rattle and sounds somewhat like the boom to anyone in the vehicle. Any thoughts would be appreciated.

UPDATE After 2 days got the vehicle back... The booming might be worse...like an empty trailer. Sounds like the rear tires are at 50 pounds of pressure. A low frequency rumble or harmonic! The mechanic noticed a similar but quieter noise on a Limited with the 18" wheels (like mine). The same car with 20"s was quiet. I drove them both and agree. I drove a 2010 and 2008 with the 18' tires. Both were quiet. I really regret trading in my '08. other than this noise the car is great. I can't believe no one else has this issue!
