Ford Edge 2007-2014: engines, AWD system, problems, maintenance tips

August 08, 2019

The Edge is a mid-size 5-seater crossover SUV. It rides on a car-based platform shared with its luxury twin Lincoln MKX, as well as Mazda CX-9. The Edge offers solid road feel with sporty handling and smooth ride.

The 2011 and newer Ford Edge Sport with a 3.7L V6 is one of the quickest SUVs.

The 2011 facelift brought a revised front and rear fascia, much upgraded interior (photos below) and available MyFord Touch with an 8-inch touch screen. The 2.0L EcoBoost 4-cylinder engine has been added for 2012, but is only available with front-wheel drive. A used Ford Edge is not very expensive, but is it a good choice? What are pros and cons and reported problems to watch out for? Let's start with the engine choices.

V6 Engines: The 2007-2010 Edge comes with the 265-hp 3.5L Duratec 35 V6. For 2011, the 3.5L V6 got more power (285 horsepower). The 2011-2014 Ford Edge Sport is powered by the 305-hp 3.7L Duratec 37 V6. Both are solid DOHC engines used in many Ford and Lincoln vehicles as well as in some Mazda products.

EcoBoost 2.0L: For 2012, the Edge received an optional fuel-efficient 240-hp 2.0L EcoBoost engine in front-wheel drive trims. It's a gasoline turbocharged direct-injected (GTDI) 4-cylinder motor. You can find it not only in many Ford vehicles but even in some Volvo and Range Rover products. As with any turbo engine, it needs to be maintained well to last.

Timing belt or timing chain? The 3.5L and 3.7L V6s, as well as the 2.0L EcoBoost have a timing chain. A timing chain doesn't need to be replaced unless it's stretched or there is some other problem with it.

How does the Edge AWD system work? An all-wheel drive is available only with a V6. It's an on-demand AWD system based on front-wheel drive, which means front wheels are powered at all times. An electronically controlled clutch located in the rear differential engages the rear axle when needed. We didn't try to go off-road with it, but with good winter tires the system works well in the snow. One of the main components of the AWD system is a little transfer case called Power Takeoff Unit or PTU, which is attached to the transmission. It's a simple mechanism with a few gears, but in the Edge it's one of the weak spots, read more below. As with any AWD system, it's important to use only tires of the same size, keep the pressure up to specs and rotate tires often to make sure they wear evenly. The oil in the rear differential and transfer unit must be kept clean.

Interior: After the 2011 facelift, with the updated instrument panel and an optional 8-inch MyFord Touch display, the Edge interior feels upscale. The rear seat space is more than adequate. Rear seatbacks fold down giving the Edge 68.9 cu. ft. of almost flat cargo space. The driver's seat is comfortable and supportive, although the large center console makes the leg room a bit tight. The MyFord Touch system takes some time to get used to with so many screens and menus.

Handling and ride: The Edge is a pleasure to drive, especially on the highway. With the V6, highway passing is a breeze. The ride is smooth and fairly quiet. The vehicle holds the road surprisingly well in turns.

Fuel Economy: The 2012-2014 FWD Edge with the 2.0L EcoBoost engine is the most fuel efficient trim level; the EPA rates it at 21/29 mpg. The 2011-2014 AWD Ford Edge with the 3.5L V6 gets 18/25 mpg city/highway, giving it the range of up to 437 miles (703 km) on a tank of gas. The 2011-2014 AWD Ford Edge Sport with the 3.7L V6 is rated at 17/23 mpg.

Pros: Stylish sporty looks, fun to drive, reasonable price, strong engine, cargo space, smooth ride.

Cons: Thirsty, expensive to keep at higher mileage, restricted visibility in the corners, a large center console takes away driver's space, electrical and PTU issues, MyFord Touch bugs, 22-inch tires in the Ford Edge Sport are expensive to replace.

Problems: PTU failures and leaks are reported by many owners. The PTU is a compact transfer case in the AWD system. It's attached to the transmission and has a few gears inside to angle the rotating torque towards the rear differential. The PTU is filled with a small amount of gear oil and is surrounded by hot exhaust parts. The owner's manual for the 2008 Ford Edge specifies the PTU capacity at 12 ounces (0.35L). If not covered by the warranty, replacing the PTU will cost over $1,000, as an OEM part alone is priced over $800 online.

Many owners at various forums and on Youtube suggest checking the PTU regularly for leaks and changing the oil in the PTU more often. Signs of a leak from the PTU include black thick fluid drops in the area to the back of the engine in the middle of the car and a bad burnt gear oil smell from under the car. The PTU doesn't have a drain plug, but according to several owners, the gear oil can be sucked out and changed through the fill plug. There are many Youtube videos on this subject.

According to the bulletin 13N02 Ford extended the warranty coverage on a brake booster in certain 2010-2013 Ford Edge to ten years of service or 150,000 miles whichever occurs first. Check with you Ford dealer if you have any symptoms of a bad brake booster, such as a hard brake pedal or a hissing noise coming from the brake pedal area.

Ford issued the TSB 07-21-11 for the Output Shaft Speed (OSS) sensor or Turbine Shaft Speed (TSS) sensor codes and/or harsh engagement, no upshift, fifth gear only, in the 6F50 transmission of certain 2007-2008 Ford Edge models. The bulletin advises following the diagnostic procedure and if found bad, replace the sensor(s). Again, Youtubers made several videos on this problems.

Old spark plugs may cause one of the ignition coils to short, which in turn can cause the PCM to fail. For this reason, it makes sense to replace spark plugs in recommended intervals or earlier. Replacing spark plugs on the V6 Edge will cost from $290 to $420.

The Ford TSB 10-21-02 for the 2009-2011 Edge describes a problem with the transmission range (TR) sensor that can cause various transmission problems, such as slipping/neutral out, 5th gear start from stop, electronic PRNDL error, backup camera on in Drive or speed control dropping out intermittently. The transmission range sensor tells the transmission computer what gear the shifter is in. For example, the backup camera may not work intermittently if the sensor cannot detect that the transmission is in Reverse. The diagnostic procedure in the bulletin involves checking the resistance between the transmission connector pins and if the resistance is out of specs, the transmission range sensor must be replaced.

The TSB 18-2013 covers the issue of the door ajar lamp illuminated with all doors closed, draining the battery in the 2011-2013 Ford Edge. A door ajar sensor that is built into the door latch might be the cause of the problem. The TSB repair procedure involves cleaning the switch using a special tool that likely only Ford dealers have. It's not a very expensive repair, however there are a few reports that the problem came back after the repair. There are plenty of Youtube videos describing the problem and repair options. This thread at Fordedgeforum.com discusses the issue. Some owners suggest cleaning and lubricating the latch with a spray. One of our friends had this issue with his 2012 Edge and he replaced the driver's door latch ($130 part) that was faulty himself. A dealer may charge $400-$500 for the replacement.
Ford issued several recalls for the Edge, check at the NHTSA website.

Overall: The Edge is one of the few SUVs that you can enjoy driving, although it's not the most reliable choice. As of August 2019, Consumer Reports rates only the 2010 Edge 'above average' for the reliability; other years of this generation are rated 'average' or 'below average'. Some of the problems might be costly to repair at higher mileage. We also checked the NHTSA website, and there is a spike of complaints about electrical problems in the 2011-2013 Edge. Still, a great deal of Ford Edge owner reviews online are positive. Many owners compliment the styling, driving experience, power, MyFord Touch features and safety. Overall, a front-wheel drive Edge will be less expensive to maintain in a long run.

A V6 engine is designed so, that the water pump is built inside and is driven by a timing chain. If a water pump fails, it's expensive to replace and the coolant might leak into the crankcase. That said, we have seen a V6 engine last for over 200K miles and the number of engine-related complaints is small compared to other cars. Considering that and other issues, when buying a used Ford Edge, a good extended warranty at least for the powertrain is worth considering.
Crash test ratings are mixed. Check at the NHTSA website.

What to look for when buying a used Ford Edge: When checking the vehicle at the dealer lot, test all the electrical accessories, such as the power tailgate and the air conditioner. Make sure the sunroof opens and closes freely. See if the backup camera (if equipped) works consistently. Earlier, there were many issues with the MyFord Touch system, including black screen, slow response, freezing, and requiring repeated reboots. Many owners had the software updated or the APIM module replaced, while under warranty. This means, research the MyFord Touch problems and test all the feature carefully. See these Youtube videos for more info. The 22-in tires and rims in the Edge Sport are expensive to replace, check the condition carefully.

Leaks under the car, as well as a smell of coolant or burnt oil coming from under the hood indicate a problem. The low coolant level in the expansion bottle might also be an indication of leaking coolant. If coolant leaks from a water pump in a V6, the repair will be expensive. Check the oil on the dipstick and avoid the vehicle if it looks like the coolant is mixed with oil, see how it looks here: how to check the engine when buying a used car. Several owners mentioned a leaking power steering hose. Before buying a used Ford Edge, have it inspected by a trusted mechanic. Ask to check for leaks, assess the condition of an engine and transmission, a water pump in a V6 and a turbocharger in the 2.0L EcoBoost engine.

Maintenance tips: Avoid overheating the engine; change the engine oil regularly and keep other fluids clean - this will prevent many problems. We always recommend regular inspections in the shop with the car on the hoist to keep it safe - at least once a year. The reason is that many components cannot be inspected in a drive-through quick lube place. For example, a bad ball joint (part of the control arm) is hard to notice unless a mechanic checks it with the car on the hoist. When bringing your vehicle for service, ask to check the A/C drain; if it's clogged up, water will leak from the HVAC system inside the car. Timely spark plug replacement will help avoid more serious problems like failed ignition coils. Consider rust proofing if you live in the area where salt is used on the roads in winter.
