chickstr Posted December 28, 2012 Share Posted December 28, 2012 Hello All, I wanted to see if anyone has ad similiar expierience. I have just purchased a 2012 Fusion SEL V6 with 20k miles on it. I have noticed that when driving at a constant higjhway speed of 70mph (+-5mph) I get a constant slight bucking feeling. I have sent it to the shop twice and service manager says he felt it as well but the techs could find nothing wrong. Tires have been rebalanced, alignment is good, no error codes, shifts perfectly during acceleration and engins seems smooth. Fuel economy is at 25mpg, which with my heavy foot is ok. Any Help or people who have run into this please let me know as it is getting annoying. Thanks 0 Quote Link to comment Share on other sites More sharing options...
FusionDiffusion Posted December 29, 2012 Share Posted December 29, 2012 Do you have FWD or AWD? If you have AWD is could be a problem with the driveshaft or the PTU. 0 Quote Link to comment Share on other sites More sharing options...
drolds1 Posted December 29, 2012 Share Posted December 29, 2012 Do you know the history of this car? The mileage is on the high side for a 2012. Was this a rental or loaner? Did you buy it from a Ford dealer? I'd ask them to check OASIS to see if this issue was ever addressed before. At any rate, this is unacceptable. If they can verify that there's a problem but can't fix it then they need to contact Ford on their dealer hotline. I assume you have the balance of the factory warranty. Under the terms of the warranty they are obligated to fix your car. They can't just give you back the car and say they can't figure it out. That's not the way it works. Speak to the service manager. If you get no satisfaction, contact Ford customer service. BTW, have they checked for a bent wheel or bad tire? 0 Quote Link to comment Share on other sites More sharing options...
3 point 5 Posted December 30, 2012 Share Posted December 30, 2012 (edited) Have them check the throttle body. It may be bad... Edited December 30, 2012 by 3 point 5 0 Quote Link to comment Share on other sites More sharing options...
chickstr Posted December 31, 2012 Author Share Posted December 31, 2012 It is FWD not AWD. I spoke with the service manager and he will be taking it in for the 3rd time next week. I will post if there is a resolve or not when I get it back from the shop. Untill then thanks for the comments and have a Happy New Year.... 0 Quote Link to comment Share on other sites More sharing options...
FusionDiffusion Posted December 31, 2012 Share Posted December 31, 2012 Well, first thing would be to make sure all your lug nuts are tight. They should also check the balance of the wheels/tires. 0 Quote Link to comment Share on other sites More sharing options...
chickstr Posted January 21, 2013 Author Share Posted January 21, 2013 Another update. Car has been in the shop for a full week this time. Service manager took car for test drive after wheel re-balance on day 1 and kept it 6 more days. I am picking it up today with their statement that a ford service engineer tech will be called in to check the issue as they could not find anything in their shop. On a side note. I was told the car may be operating within ford design tolarances... Does bucking/pulsating at a range of highway speeds souns like acceptable tolarance to anyone? I'll keep updating this untill a resolve is made or I give up.... 0 Quote Link to comment Share on other sites More sharing options...
fusionfamily Posted February 5, 2013 Share Posted February 5, 2013 Bucking - no. Pulsating - maybe if you have a bad tire - do you have the regular 17" rims w/Michelin tires or the sport 18" rims with GY Eagle RSAs? 0 Quote Link to comment Share on other sites More sharing options...
Got2BAFusion Posted March 3, 2013 Share Posted March 3, 2013 as an owner with a high milage 12, I purchased mne in Sept with 31K on it, just turned 40K. I have done two long range trips (one 900 miles round trip, one 1800 miles round trip) and have not sensed any bucking or pulsating on the highway. I drive just under 5 over and am a heavy CC user and typiaclly feel every thing that happens in my cars. I have the extreme cold delayed shift (just use it in manual mode until warm) but no other bucking/pulsating issues. Hope you get it figured out with the shop. 0 Quote Link to comment Share on other sites More sharing options...
Xyzzz Posted May 2, 2013 Share Posted May 2, 2013 My Mercury Millan, 2011 with 17000 miles has the same issue. Jerking at constant speed. Ford tried to find the problem, no luck, including calling their hot line for TSB,s and transmission expert. They reprogramed the tranny so maybe that will help. They said AC cyclying off and on but that is not it as it does it even without AC. I think it is a transmission problem, not cruise. I added fluid to bring it up to top of mark. Previous forums say that helps, and it did make a noticeable improvement, but still not totally eliminated. 0 Quote Link to comment Share on other sites More sharing options...
con_fusion Posted May 3, 2013 Share Posted May 3, 2013 I have a 2010 and never experienced this but I did recently replace my throttle body because the car simply died on my wife when she hit the throttle. Classic sign of things to come. I know the 2011's and 12's probably had the latest throttle bodies but I'm wondering if anyone with this issue has had the TB replaced. Seems like service should have at least tried it. The part is fairly cheap for them and it would take them minutes to replace. If you are having this problem, see if you can talk the service manager into replacing the TB. 0 Quote Link to comment Share on other sites More sharing options...
chickstr Posted May 3, 2013 Author Share Posted May 3, 2013 Update. Issue was not solved. Here is what the dealer tried. New throttle body Alignment Wheel balance New injectors Checked all air dams and deflectors New plugs Lots of computer resets and updates On my last dropoff to have it checked I got an identical 2012 fusion for a rental from enterprisel. Guess what?? It did the same thing. I have personally written the issues off as a ford design mess up. This will be my last ford car. If anyone ever finds a solution please post findings. 0 Quote Link to comment Share on other sites More sharing options...
FusionDiffusion Posted May 3, 2013 Share Posted May 3, 2013 You said it happens when you're at about 70 MPH, but does it only do it with the cruise control on, off, or both? Have you tried gas from a different station? Higher octane? Does it happen constantly at the specific speed, or does it gradually get worse until you do something like take your foot off the gas? Or does it come and go on it's own without doing anything? Did they bother checking fuel pressure to make sure it's stable? 0 Quote Link to comment Share on other sites More sharing options...
crash525 Posted October 3, 2014 Share Posted October 3, 2014 Another thread about the same issue I have been having. I am taking my car in in a few days. Ill see if they can come up with anything. The mechanic said he thinks he knows what it is. also there is another post about this. http://www.fordfusionforum.com/topic/10467-2012-30-stutter-hesitation-at-highway-speed/ . I have not been able to find a answer. My guess it is that while cruising it could be the motor mounts. They are very weak. They look like the same ones from the 2.5l. My motor mounts will bottom out if i let off under hard acceleration and accelerate quickly. A dealer had adjusted mine and the problem became more prevailent. 0 Quote Link to comment Share on other sites More sharing options...

edgedout Posted May 20, 2015 Share Posted May 20, 2015 I had a 1993 s-10 pickup truck that drove me insane. At about 70,000 miles it started bucking between 50 and 60 mph. Took it to 3 different shops and the dealer. No fix. Sold/gave it to my son who knew a guy who could fix it. Didn't happen. Son got rid of it. I looked at this thread to see if the mystery would be solved, Guess not. I think its in the cars computer, but who knows. 0 Quote Link to comment Share on other sites More sharing options...

Dofelmire Posted September 24, 2015 Share Posted September 24, 2015 Yes we still are having the problem. The car is sitting in the shop for the sixth time to fix this problem. TB has been replaced. Fuel injecters cleaned and flushed. Plugs changed. EGR replaced because they felt it was coming on to early causing the bucking feeling. Well still didn't fix it. The last time it was here they replaced the PCM computer and it still didn't fix the problem. With me driving it like crazy I have been playing around with it and this is what I have found. It does the feeling all the time but to make it really apparent when the car is at 40mph. 4th gear using manual selection. In between 2000 to 2500 it misses and bucks bad. Now I have noticed if just sitting in the parking lot and rev it to that window you can feel the engine miss while just idling. Someone please tell me they have took their car in for this problem and have been able to find a fix for it. It's driving me crazy and I'm sure ford did design a car to do this problem 0 Quote Link to comment Share on other sites More sharing options...

Dofelmire Posted September 27, 2015 Share Posted September 27, 2015 61000 couple miles from it. Got the car back today and it's still doing it. They said they replaced a gasket for the EGR because of a high pitch noise from the EGR. Problem isn't fixed. Second they said the plugs needed to be tight because I was having a miss fire. Well still does it and acts like they didn't even touch the car. I'm so tired of Ford right now it makes me sick. They said that until a error code or light comes on there is nothing more they can do. Just makes me sick 0 Quote Link to comment Share on other sites More sharing options...

Have you been to another dealer for a second opinion? Meagan 0 Quote Link to comment Share on other sites More sharing options...
Dofelmire Posted September 28, 2015 Share Posted September 28, 2015 Yes we have and they said it was the A/C cycling on and off. Only problem with that is the whole heater system was turned off. I just rode with someone today in it and he asked if I had bad plugs. Told him Ford just checked it and all was good plus they have been replaced. But pretty sad someone riding in the car noticed it but the dealers and techs are saying its normal. 0 Quote Link to comment Share on other sites More sharing options...
