I have a '17' that came with and still have the Michelin energy saver X tires...What I've has said and noticed with these, they do ride hard and are really noisy especially in hotter weather...But I have no vibration at any speeds. I was going to say you have a bad batch of tires out of round or some defect that balancing won't correct...I do keep the cold pressure at 36 psi...I have the 235/55/17 size.....Dont know about the active grill, but thinking in cold weather is when they really operate, partially close to help speed up engine warming,, always notice in summer they are wide open..so it's temperature dependent I believe, not speed...I wrote about the TSB17-2207 governing this issue in that thread, but adding here to show my experiences.
I have been having this vibration problem, noticeable right after the dealer rotates the tires, coming in at 60MPH and worse on sweeping right turns and when crown of road tilts downward to the left, felt worse in body, not steering wheel. (If it was a noise, I'd call it a wheel bearing, I think something more might be happening than wheel balance, but what do I know?).
They get perturbed that I might be blaming them (not), but they have balanced them numerous times and even used Hunter Road Force balancing. After the last time (I returned from a 1000-mile drive to my hometown with no issues, had the 10K service, bad vibration at speed returned), I got a bit more firm and wanted further review/analysis on what is causing this vibration.
The service manager went on a long road test with me in June 2019 (but as a passenger, not driving), and feels the problem, said that rotation wouldn't be the cause, and probably normal to the vehicle. To be fair (Letterkenny anyone?), the Asst SM said he also has an Escape, and it has the vibration, also, the loaner SE also had the same vibration.
They did another Hunter Road force again, and basically, the results are what are called luxury car levels, NPF (I did note that they did not road test the car more than 2 miles). Later, I called Hunter and got the regional rep. He knows and trusts my dealer (as I do), but suggested I get a second opinion at an independent shop that has a newer Hunter machine. Independent shop owner was very knowledgeable person, did another Road Force balance, and vibration remains.
I can almost accept that this is normal, but if a problem, probably other issues to review that no one is addressing (and, might not be able to until a larger fault shows up):
May be normal to base Escape, due to compliance designed in the bushing/struts - the SUV IS great on gravel roads, able to maintain a high speed compared to my Fiestas);
Maybe the transmission clutches are grabbing at that speed? I use cruise control a lot, and the vibration seems worse on decel down a hill;
What is different on 2017-2018 models from the models before? Did Ford began to put the Michelin Energy Saver a/s tire on 2017 models, not before? I personally think they might not be too great, hard and designed for gas mileage and nothing else;
The new design has "active grill shutters" - at what speed do they become active? Partly closed beginning at 55-60, fully closing at 70? If so, the partial closing is right when the vibration occurs, aero imbalance bouncing the SUV?
One Person said to raise tires pressures drastically to force roundness on tires; I reduced pressure to 32 on my calibrated gauge, and the vibration gets minimized (and, much more comfortable ride).
Personally, I can almost accept that it is endemic in the the design, and not a fatal (get rid of the SUV) flaw, and really think the tires are crap.
This is not related to the vibration issue that this thread is discussing. I would think vibration and surging are two different thingsHey all,
Around 100k miles was having some surging problems, which, as it got worse, started to include car randomly shuttering at highway speeds.
Check out this thread.
PROBLEMS SOLVED: CHANGED THE AUTOMATIC TRANSMISSION FLUID.
Well my surging was getting worse. It had gotten to where any acceleration beyond 1/4 throttle and it would surge or miss in an on/off/on/off pattern. Another user posted about erratic acceleration and said he swapped out the turbo solenoid and fixed his issue. I did the same, took 45 minutes...www.fordescape.org
Fluid change fixed the shuttering and uphill surging problems. Problems started around 99k miles, and I got it resolved at 108k miles. I noticed some posters on this thread said they were around 100k miles. Since the manual doesn't call for doing ATF change until 150k, most people probably won't try this as a fix, but its easy and cheap, so it couldn't hurt. And if you are doing certain activities like going on dirt roads or towing, I think the manual calls for ATF change every 30k miles, so some people may be way OVERDUE for the change and just not notice unless they checked the fine print in the owners manual.
My 2014 (136000K) has the same vibe/shake issue. Intermittent and not too severe. I told the wife to ignore it until it got really bad and then the problem is sometimes easier to find. After reading these (and other) posts, it seems the transaxle was a popular suggested cause. After checking, I found the passenger side inner CV boot was trashed and obviously the joint as well. These forums are really helpful. In another example, a few days ago I was chasing a check engine light for an emissions code PO450 (fuel tank pressure sensor out of range) on the escape. I came across some discussion around problems with rust coatings gumming up the sensor vent holes. The person had actually posted a photo and because of that, I was able to locate it and spray it with brakekleen. Goo is gone and so is the check engine light. Thanks to all who contribute!Hi all,
2014 SE 1.6t here with 110k. Recently my car has begun vibrating under power at highway speeds. As soon as I let of the accelerator the shaking stops. when it first started it felt similar to a wheel out of balance, but after rotation it continued, and now it has gotten progressively more violent. I have recently replaced the drivers side CV axle which did not solve it, passenger side CV axle seems fine. I took it to the shop for an oil change and to get the coolant level sensor installed and it seemed to be better for a week after being in the shop, but has since started occurring again. Also only seems to happen after driving for 10+ minutes. Has anyone else experienced this? Has anyone else experienced something similar? My next thought would be motor or trans mounts, as it sometimes feels rough when shifting between park, reverse, and gas. If not than I suspect an issue with the transaxle. Any help appreciated.
I merged your thread with this existing thread on the same topic. Have a look at the other posts for some help.Hi,
got a vibration problem with my 2014 Ford Escape AWD with 91,000km/56,000miles down.
The vibration is coming from the rear end.
It's only happening after starting to drive and goes away after 1-2 miles.
Now that's getting colder (up in here in Canada) the vibration is worse than in summer.
The vibration doesn't come back till the car is parked for longer time .e.g. overnight.
Tires are new and balanced but the vibration was there before old and after new tires.
The dealer is useless they said/done everything from dirty rims, unbalanced tires, damage rim -they just didn't listen to the fact it goes away after a few miles.
I'm not an expert but could it have something to do with the rear diff fluid?
Does anyone have an idea what the problem could be? - don't want to take it to another shop and listen to stupid comments.
