#14724 Overheating

Posted by 69cat on 24 July 2015 - 08:01 PM

Finally found the problem. The small white wire with a blue stripe coming from the PCM. rubbed on the plug-ins plastic housing ,right where it plugs into the module, cutting a small hole in the lining of the wire which caused the wire  to corrode and created a short. If your fans aren't working check to see if you have resistance, with a omhs meter,  between the small wire in your plug-in and your battery's  ground. If you have no  resistance  switch leads try again, if you still have no resistance check your wire right where it bends over the plug to see if there is a small cut in the wire you may have a short ..... Maybe I just got lucky.

#14592 Anyone have any transmission problems?

Posted by crazyguy6 on 12 June 2015 - 07:02 AM

Ok, some new information on all these shift issues. It appears that the Transmission Shift Module can cause these problems but not throw any error codes. In talking with a undisclosed individual, Ford techs have been replacing the shift modules Like Santa handing out candy canes at Christmas time.


Most Dealers sell them for $400 or higher plus the labor but if you are a handy car guy, you can pick them up for as cheap as $290 like TASCA Ford on line. The particular number for our 2009 Flex is AA5Z-7G391-A and it fits a number of models with this transmission.   


The symptoms of my transmission are erratic shifting, hard shifts and its favorite trick is jumping out of gear in heavy stop and go traffic.  Most of the time when it jumps out of gear or wont go back in gear, you have to pull over, put it in park, shut the car off and restart it. This sequence always seems to correct the problem for a while.


I've also tried re-setting the module by disconnecting the battery for a few hours then reconnecting it and driving the car. It usually take the transmission a day or so to calm down from re-learning the shift patterns but it is usual a process that involves long / jerky shifts.


The reason for giving you this information is to show how an electrical based part can wreak havoc on your transmission. Basically, Don't let them talk you into a $2,500 to $3,000 Transmission replacement when you could have something more minor going one.  Our local dealer has replace 11 of these already this year and they keep 2 in stock at all times so this tells you the severity of the problem.  Even if your Transmission is not exhibiting or giving out any error codes, the local dealer still replaces these and most often has success in solving these problems that are plaguing these style of transmissions.


Good Luck and hope this helps.

Is there any sign that FMC gives a care about you?

#12297 New to forum, 2013 Ford Flex Limited, Tuxedo Black

Posted by WickedFlexnamedLexi on 30 May 2013 - 07:17 AM

Never joined a forum, but I have read plenty of info on them.  I just retired my 2001 Ford F-150 with 362K miles on original engine/transmission.  Bought my Flex in March.  Loving how comfortable this vehicle is on long trips.  Just waiting for Ecoastal Tech to get the Lock Pick worked out for video in motion.  I've already removed the rear third row seat and added 4-10" subwoofers and rewired all the mids and highs and put them on a different amp than the stock Sony.  It sounds AMAZING!  My F-150 has 8-12" subs and 6000 watts and is simply INSANE, but the Flex sound quality is better.  Anyone needing help with entertainment in their Flex with FMT, just ask.

#12165 Our Big Red Blur

Posted by Chad Osuna on 01 May 2013 - 07:37 PM

We have had our big red Flex for about 6 months now and everyone in the family is obsessed with it.  Trying to do a few tasteful mods, but in the end we feel our Flex is a work of art cruising down the road.

#12131 Proud owner of a 2013 Flex Limited!

Posted by Resstation on 28 April 2013 - 07:46 AM

I had a Honda CRV that was 8 months from lease end so I thought I'd start researching vehicles to be sure I made a good decision when the time came. I have never owned a Ford but liked the way the Explorers looked on the road. I drove into the dealership on Friday morning and fell head over heels in love with the Flex Limited on the showroom floor. At nearly $48K, I was certain there was no way it was in my price range but FIVE HOURS later I drove out of the dealership with the most beautiful car I've ever driven! Ruby Red, white top, LOVE it! Can't wait to figure out all the bells and whistles!


Oh, I was reading the manual and read a passage referring to the "key holder" but I can't find it and it is not referenced again in the manual. Is there a place to put the key that I am not seeing?

#12041 New Flex Owner. 2 Fords, 1 more to go

Posted by RodericB on 09 April 2013 - 05:44 AM

Hello everyone.  Let me just say that I never intended to purchase Flex let alone a brand new one.  I took my wife along with me to look at the 2013 Taurus which I was intending to purchase.  My wife has never been a big Ford fan with the exception of my F-150 (first vehicle we purchased as a married couple).  While we are at the lot looking at the Taurus, the Flex catches her eye.  Now this is a woman who was bent on getting an Infinity SUV as her next vehicle.  Next thing I know we are sitting in the Flex and she falls in love with it.  Next thing I know, She wants a Flex, not just any Flex but a 2013 because she likes the grille.  Well 2 weeks ago, we bought a 2013 Flex SEL.  She loves the vehicle and it's growing on me.  More importantly, we are 2/3 the way to being a fully Ford family.  Once I trade in my BMW next year for a Taurus, the assimilation will be complete.

#11754 Anyone have any transmission problems?

Posted by FordCustomerService on 25 January 2013 - 01:45 PM

2013 Ford Flex SEL FWD purchased on 01/19/2013

Got the car on Saturday. Today (Monday), I pull out of my spot and feel hesitation and notice a yellow wrench light. I stop the car and turn it off and on, still see the light. I decide to keep going a few hundred feet and the drive is completely off, vibration higher that usual, and transmission feels wrong. I stop the car and turn it off. I check the manual and the yellow wrench means powertrain failure. I went to start e car to move it into a better location, but it won't start. Dead.

I call the dealer, and the salesman turned me over to service. I had to call Roadside Assistance and get dropped off at the dealer. They gave me a free rental car and told me that they would call me tomorrow.

I'm not sure if this is related to the problems other drivers are having, but thought I would share my story for a brand new 2013 model.


Hi John Wiskowski,


I want to get this in the hands of your regional customer service manager by escalating your case. To get started, send me a PM with your VIN, preferred servicing dealer, current mileage, and daytime phone number; I'll handle the rest.

#11216 Is it bad to floor it?

Posted by Waldo on 06 June 2012 - 05:24 AM

It's not bad for it at all, in fact it usually helps keep the engine clean. The Flex has a rev limit built into it from the factory. You can't make it rev higher than that. If the factory didn't think it was a good idea to rev the engine, they wouldn't let you do it.

#10913 Ordered 2013 Flex today

Posted by Suzee on 06 March 2012 - 09:58 AM

Well, it's been ordered.....and now the long long wait begins!

Ordered a 2013 Flex EcoBoost in Ruby Red, with so many bells and whistles I can't believe it. I've never had a brand new car before, let alone have one made to my specs.

I feel like a kid waiting for Christmas....

#5407 Fuel Economy

Posted by QSHIPWAGON on 29 December 2009 - 08:36 PM

I just took a short highway trip (15 miles) and noticed that I couldn't do better than about 22-23 MPG at an average of about 70 mph. Not that impressed!

Are you sure? You've got a 2+ ton, well appointed, fairly clean burning 7 passenger vehicle capable of producing well in excess of 300++ HP that's shaped like a shoe box that's not even broken in and you're getting 23 MPG using RUG on a short trip at 70MPH and you're dissatisfied? C'mon.....

#4244 Dealer Says All 2010 AWD's Are Being Held Due to Faulty Seals

Posted by Waldo on 17 August 2009 - 05:20 AM

That's a whole different thing to say than they're not comparable. Of course they're comparable... but for you the experience is one you wanted. Believe me, as someone who has been teaching high performance driving to students for nearly a decade I understand the lust for speed, horsepower, torque, and whatever else a powerplant can deliver to the soul of a vehicle. The Eco sounds like a fine vehicle and I wish you the best of luck with it. I just put my Flex through a course we set up for teens at one of our driving skills schools. It behaved admirably for what it is. In this case, HP and torque would have not made a difference... as much as I love the Flex, it exhibits prodigious amounts of understeer especially with the AWD system and the tires were pretty much spent after a single lap of only about 300 yards. So much so, I wondered if I had a tire going down. Drive safely...!

The Ecoboost Flex has a substantial retune of the suspension compared to the 2009, so it's more than just the HP and torque.

#14041 Battery terminal corrosion

Posted by robertlane on 07 March 2015 - 05:28 PM

I bought this 2011 CPO Flex last June, it came with a new battery.  The positive terminal was pretty corroded when I finally got it home and looked the car over real close.

No big deal, I figured I'd clean it myself, that was 8  months ago.

Yesterday I finally did the cleaning job with a baking soda/water mix and various brushes and scrapers, it came out pretty clean, so far so good.

Next I installed those green/red anti-corrosion pads around the battery posts and gave everything a thin coating of dielectric grease.


I'd disconnected both terminals, when I went to reconnect them the horn alarm went off and the only way to stop it was to pull the negative terminal.

I tried this a few times but each time the horns alarm would honk. The Owners Manual was no help.

I was frustrated, I've cleaned lots of battery terminals on my cars with alarms and never had this happen.


I got on the internet and looked up this issue, a Mustang Forum had a suggestion and I tried it.

I put the key in the ignition, turned it to the Accessory position and then connected the negative cable, it worked, no alarm.

I learned something new. 



Exactly.  That's they way that we used to do it @ Shelby with the 2005-2014 Mustangs.

#12978 Potential for door rust?

Posted by flashbackwoody on 02 January 2014 - 10:38 AM

the potential for rust is huge inside the bottom of the wrap around and under portion of the door cavity. i pulled the vent flappers from the bottom of the door and inserted a piece of vinyl tubing that reaches all the way to the other end of the cavity and used a oil can to squirt heavy viscosity 80-90 gear oil into them and then let it drain out onto cardboard. I do this twice a year. It is the 'only' thing that will stop the rust you will see upon inspection of pretty much any Flex that has spent a few winters in the salt n' sand belt of the continent. The rear of the front fender is a spot that you will find bubbling already as well

#12290 Brand new flex fanatic!

Posted by 88forlife on 28 May 2013 - 08:37 AM

Just bought a 2010 flex limited ecoboost tuxedo black with ingot silver top.

We absolutely love it!

I have owned three fords in my time and even a few Chevys and foreign cars.

I currently drive a 04 f150 and while having it serviced we decided to look at the pre owned vehicles they had on the lot. Since we had just been hit the previous weekend by a drunk driver with no DL or ins. Which totaled our Honda gas saver/ get the kid a stuffs around town.

I had seen a couple flex's around town and liked the styling but never really gave it a second thought.

We were looking for something comfortable but enough room to carry my "toy car"( not my words) rc racing hobby around with us. But still get descent mileage to help with fuel costs each month.

So we stumbled across a 2010 flex limited. Well lets say it caught our eye. Very attractive car especially in what I now like to call bass boat black or what they call "tuxedo" lol

So we drove it and yada yada yada....we have now owned it for a month.

I not only drive rc cars but occasionally real life race cars on the weekends. I have driven many vehicles in my short yet active time of 30 years.

Few cars have ever really made me scratch my head and put a big a$$ smile on my face at the same time. This car is the definition of sleeper. I let the lead shop foreman at our local Hendricks Chevy dealership drive it also. He had the same reaction I did I quote " it's like a corvette that seats 6". Not only is it no slouch in the pony department. I towed my boat up to 6000 feet a couple weekends ago and I swear it tows it better than my f150 and got 15mpg doing it, not 10-12. Small gain but that adds up.

So needless to say I am loving this CarUV on steroids. It's fun to drive even in fuel conservation mode getting around town and what not. We get comments everywhere we go. ie I hate getting gas now cause every time someone want to ask a million ?s about it. Well I don't hate it but it you know what I mean.

In closing I want to hear some of the upgrades people have done. Do and don'ts and any other comments you may have.

#10000 Thinking of buying a FLEX

Posted by deub on 28 September 2011 - 08:43 PM

After some researching, I see no reason for concerns with reliability. Note, by buying the optional maintenance/extended warranty offer for under 5k you can lock ALL (no fees for oil changes or periodic services) your costs for 100k miles or 7 years. I did it without hesitation. Don't forget that with 0% financing your locking in the labor and parts price to current rates too. Nice knowing too that I won't be exposed to any unexpected costs for next ~7 years. 0 % can't be beat, so use it to calm your reliability concerns and trim your routine maintenance costs.
