Very annoying vibration in vehicle

[Dodeboost]

You are absolutely right I have been playing with sport mode and the only thing I don't like is it holds 5th gear too long you almost have to give it gas to shift at 45-50. What urks me most is I've never had a car vibrate and chug in normal mode. Love stick shift but you have the choice to shift into any gear you like and you know what the outcome will be. Chugging or revving Or burning rubber! Ford's normal mode is the same as eco and it sucks!

Yep. Hopefully this can be fixed with a simple software update to the trans control module. Too bad mavericks aren’t available with a 5 or 6 speed manual because that probably what I would have bought. I wish it at least had paddle shifters

Just got back from dealer! brought my Maverick in 2nd time for vibration that emulates thru steering, when normal driving and just giving slight gas to pedal.
was told by dealer that that the vibration was normal. They said it`s part of fuel management theory! vehicle is in 6th gear at that speed for fuel savings. And nothing could be done to change it. Am I nuts and the only person feeling this most annoying effect? I thought about looking for a tune that I could reprogram shift speeds to compensate or just sell the truck.
please tell me I`m the one feeling this.

I have this same issue, severe vibration under slight exceleration and deceleration when below 2000rpm. Vibration has gotten significantly worse over time. Now it sounds like something has vibrated loose because I have a horrible rattling noise to go along with the vibration. Been in for service twice with dealer saying they can feel it but it is normal. Can't even get them to document it in the service notes. All they document is no problem found. Going back in for the third time tomorrow so we will see what they say this time. I have already contacted an attorney and suggest anyone else with this problem do the same. Other issues I have had are the brake staying on problem which was fixed and now my radio likes to stay on and I cannot turn it off without disconnecting the battery.

My short term solution is driving in sport mode. Under light acceleration the shift points seem more appropriate, around 2500-3000 instead of below 2000. I don’t like the engine braking but I’ll take that over lugging the engine. Normal mode seems to shift to higher gears way too soon

would love to know what that dealer has to say. This seems to be the case with all 2.0 MAVs and normal mode def needs a tweaking by Ford. It’s good usually but sometimes upshift when it shouldn’t resulting in lugging/vibration. I have the same thing with mine and have found tow/haul to be a bandaid till Ford comes out with a TCM SB and flash. Hopefully.

Seems the Cobb/Access-Port really helps with shift point management- FYI

Well, got it back from second dealer they pretty much told me the same thing, normal as you said I have been driving in sport mode also I will live with it until they come up with a solution. I don't think many drivers have complained yet so it may take a while. I'm scheduled to have side bags replaced so I may try to have their trans tech go for a ride with me. That may be a while as bags are in short supply will update any news.

Disappointing for sure cause normal mode is mostly good in that it generally keeps rpm’s at 1500 or higher which is it’s sweet spot. I have a 2001 ranger I4 manual 5 speed and it’s sweet spot is 2000rpms or higher. Current MAVs try and make power below 1500 in way to high of gear at slower speeds as this thread is all about. Very annoying and disappointing.

Here is a quote by someone else either in this thread or a closely associated one and he nails it perfectly. Ford needs to see this if they already have,t.

”
Mine does the exact same thing and is most obvious around 35 mph. It actually happens at any speed where the engine is below 1500 rpm and the throttle is applied (lightly enough that it doesn't downshift or unlock the torque converter). The vibration and noise, caused by the lugging, is just much more noticeable at low speeds because there is less road & wind noise/vibration.

I'm a mechanic with over 30 years of experience and it's obvious to me the problem is in the PCM/TCM programming. The programming is keeping the transmission in too high of a gear and keeping the torque converter locked, which is causing the vehicle to lug (like a manual trans in 4th gear when it should be in 2nd). This lug is causing engine/transmission/driveline vibration until it reaches that 1400-1500 RPM point. I'd guess this programming was done in an attempt to keep RPMs as low as possible for gas mileage, but it definitely causes unwanted (and possibly damaging) NVH (noise, vibration, harshness). Plus, the only thing that prevents the lug is pressing the throttle hard enough (probably about 25%) to cause the transmission to downshift which will definitely use more fuel. Ford needs to change the programming (put out a TSB with a reflash) to, at a minimum, unlock the converter on throttle tip-in below 1500 RPM (and probably have the trans drop a gear as well). I hope more people pay attention to this issue and report it to their dealer. We also need to tell the dealer to report it to Ford corporate, so they realize there's an issue (which I have already done, but it will take far more than one person).”

Andrew1966 has given his observations on how to best avoid the droning / shudder:

"Mine does the exact same thing. It’ll decide to upshift when it was just fine at 15/1600 rpm yielding 11/1200 rpm and “lug” until you press down on the accelerator. VERY annoying. Shift sequence on acceleration say 0-60 is perfect. What I have found is that in general a speed ending in a 5 and if you stay on that speed……wI’ll prevent an upshift usually. So going through a 25 I set the cruise at 25……35 and 45 the same. Driving in normal mode at 30 will put you in a lugging 1200 rpm.

A work around for me, (at least till Ford comes out with a new TCM bulletin and reflash), is to use tow/haul when driving around town. Normal mode for everything else."

It's a different way of driving, but for the most part, it works.....

Have the same problem on my FX4 4K EB Maverick. Accessport does help but it is not the complete solution. I think Ford just slapped some random TCM programming with this 2.0 ecoboost motor and called it a day.

what tuner do you recommend?

I have only used the sct with 5 star tunes but you can set shift points and firmness plus a lot of other stuff.

I had this start happening slightly after I bought new tires on one of my vehicles. It ended up being one of my tires developed a slight egg directly in the center of the threads. Once because I lost a weight on my wheel. It occurred between certain speeds.
You can check these two yourself if you want.

Dealer cant fix it until Ford sends out revised pcm flash

your not describing the issue at hand unfortunately. We are not talking about an unbalanced tire but rather an upshift into 6th gear at low speeds yielding a lugging of the drivetrain at < 14-1500 rpm’s.

Glad you have narrowed it down already.
