Ford Flex has been one of the most successful lines of vehicles. Some owners believe that the track divided into two generations; however, believe it or not, there is only one generation of the Flex. The line started in 2009 when Ford discontinued several other models and took parts from all of them to create a new vehicle that would be more competitive in the market. To some, this is considered a truck to others; it is viewed as an SUV. No matter what you call it, it is fun to drive!
Though the line has been hugely successful, it has not been without its issues. A lot of the quirks that you will find with the Flex seem to revolve around at the electrical system. In this article, we dug deep to bring you the best information that we could.
Here is a list of the most common problems with the Ford Flex:
- Swollen lug nuts
- Door ajar light will not turn off
- MyFord Touch technology is faulty
- Engine failure
- Cooling fan module
- Throttle body failure
- Electrical system
- Power assist steering disables
No line of vehicles has without its issues. Anytime you have to rely on mechanical or electrical systems, and there are bound to be problems. Components fail designs get improved upon all the time. We are not trying to dissuade you from purchasing a Ford Flex. We are merely just bringing the most reported issues to you so that you can make an informed decision before purchasing a vehicle. As mentioned before, this is one of the most if not the most successful Ford line. It is extremely popular with both truck lovers and small Vehicle drivers. The famous characterization is that this is a truck, but it handles like a car. With the power of a truck.
Some of these problems have been worse than others. The following information is not broken down in terms of importance or danger. These are just the most common issues with the line. Of course, there are other issues, but in this case, they were not frequent enough to include in this list. Follow along with us as we explore ford Flex problems.
This list may seem alarming, but when you consider the fact that the Flex has been in production for ten years, it isn’t that bad. We scoured every Source from online forums to official Ford recalls. Here is what we have for you.
The early years of the Ford Flex, namely 2009 to 2012, had some issues that are typical in new designs. Ford addressed some of these issues via recall. Others have been reported by owners and not acknowledged directly by Ford. The 2012 to 2019 model years have had some problems but relatively few compared to their competition.
Swollen Lug Nuts
Swollen lugnuts sound a bit funny, but it was bad enough that a lawsuit was filed against Ford. The complaint was that the lug nuts would swell and lock. This condition made it difficult, if not impossible, to remove them. It may not have been such a big issue for the folks at tire shops or mechanics that had tools to remove them. But you can imagine the frustration that exists for the person that had to try and change tires on a busy interstate. The lawsuit against Ford was dismissed. As it turns out, the actual lug nuts were not the issue. Ford came up with a new design, and they kept each lug nut with a metal cap for decorative purposes. The Caps themselves would swell up, limiting access to the actual lug nuts. It was deemed not to be a genuine safety issue.
This problem has actually been a reasonably prevalent issue with the 2010 model, the V6 EcoBoost. There were several issues with the design of this particular vehicle. Ford did place a recall on this. The issue stemmed from battery cables that were not secured. This problem caused an electrical Arc and disabled all of the electronics on the vehicle. In some cases, owners reported pressing the brake pedal while in traffic and completely losing power in the unit. Luckily there were no deaths injuries just frazzled nerves.
Door Ajar Light Will Not Turn Off
This problem is more annoying than it is a safety concern. On several models of the Flex, the sensor on the door fails, and the vehicle continually thinks one of the doors is open. When owners would step on the break and come to a stop, the vehicle’s electronic warning system would advise the driver to place the truck in park and shut the door. For a while, the accepted solution was to clean the sensor. The actual solution turned out to be replacing the entire door, and sensor assembly as the original sensor was faulty.
MyFord Touch Technology is Faulty
Electronic issues have been a big hit to the Ford Flex line and the automaker in general. There are several claims that the automated system that controls entertainment and various functions of the vehicle is slow or unresponsive. This defect has caused fuel mileage problems navigational issues in general complaints about the reliability of the unit. A large portion of these consumers complained that there are no real knobs or manual radio controls, and all of the commands are reliant on touch screen technology. There is currently a 17 million dollar lawsuit working its way through the federal court system. As of now for the solution to the issue is that Ford will provide software upgrades making the reliability of the system better.
Throttle Body Failure
There have been reported issues of the throttle body failing in the Ford Flex. This has not been a frequently reported issue; however, it has happened, and it has spanned over several year models. The mechanics in the throttle body bind up and cause the engine to shut down. This issue can happen while you’re driving, and it will affect your ability to accelerate. The consensus is that some of these components fail, and there is no particular Rhyme or Reason to it. There have been reported cases where this issue will cause a total engine shut off. You should be aware of this when purchasing a Flex because it spans throughout its entire existence. In the event of a full engine shut off, you will lose complete power that includes steering and acceleration.
Cooling Fan Module
There have been instances reported of vehicle overheating while in traffic. When the vehicle accelerates to average speeds, the temperature usually returns to normal. This problem appears to be intermittent and can come and go at any time. The usual solution to this is to have the module replaced. This fix was determined through a lot of trial and error by mechanics. Ford did not provide a suitable solution to this problem as it was just variable, and there was no specific pattern.
Just about everything in the Flex is controlled electronically. And given that there is an entire slew of reported issues with various electrical components. There has been a reported issue with just about every sensor in the vehicle. Keep in mind these reports are widespread. When you sell so many models of a vehicle over the years, it’s bound to look bad just by sheer numbers alone. There has been no single cause pinpointed, and most owners have new sensors installed. There has never been an official recall by Ford for this.
Power Assist Steering Disables
This could have fallen under electrical system issues, but the severity of it warrants its mention. In some models of the Flex, namely the 2013 model instances have been reported where the power assist steering will disable. When this happens, steering becomes difficult, if not impossible, because the power steering is controlled electronically in most Fords. There have been reports of this coinciding with total engine shutdown and loss of control while driving the vehicle at speed. That doesn’t sound like much fun. Most reports of this happening occur at slower speeds. The vehicles have been able to pull over to the side of the road, but in a couple of the instances people we’re stuck in the middle of Interstate traffic and blocked Lanes. The cause of this has never explicitly been discovered; however, it is comedy most mechanics and shops start targeting the relay system. Ford has provided no specific solution to this.
There have been some instances in the 2009-2011 Flex where the airbags did not inflate correctly after deploying. Ford did issue an active recall and will work with dealerships to replace them as needed. The cause of the problem was never publicly disclosed, but it has been fixed. The trucks that were affected were built with the Takata airbag. If you suspect that there may be an issue, take your vehicle to an authorized Ford repair facility to have this looked at.
Cracked Fuel Delivery Module
Issues were reported about the fuel delivery module developing a crack. This would allow fuel to leak. This recall affected the 2013 Flex police interceptor model in particular and presented an immediate fire hazard as the fuel would leak into an area containing active electrical circuitry. Ford has worked with its dealers to fix the issues. If you have purchased a model such as this, you should take it in and have it inspected.
As the design has progressed over the last ten years, several improvements have been made. Plans change materials change; the market is always about change. The Flex has remained relatively unchanged over ten years. There are some new trim packages, some different motor configurations and electronics are ever-evolving. However, the base design has hardly changed. This is a great vehicle to own and drive. If you are looking for a car that is going to provide you room and towing capacity, this is a good contender. You should always be armed with the most up-to-date information when you’re considering a vehicle. Safety is still the first priority, no matter how good the deal may be.
