Engine choices include a 4.6-liter or 5.4-liter V8, a 6.2-liter V8, a 3.7L Duratec V6 and a 3.5-liter EcoBoost V6. The 3.5L Ecoboost V6 offers decent fuel economy for a 4WD full-size truck.
You can choose between a 5.5-foot, 6.5-foot or 8-foot bed.
The F-150 is a solid, easy-to-maintain truck, but there are several common problems to watch out for. What are the reported problems? What to look for when buying a used F-150? Let's start with the problems:
2009-2014 Ford F150 Reported Problems:
Blend door actuators:
2010 Ford F-150.
The actuator is a small part that operates various blend doors in the HVAC system. Symptoms of a bad blend door actuator include a clicking noise from under the dash when changing the HVAC settings or issues with the HVAC system. For example, when the air from the vents is hot on one side, but cold on the other side.
The part is not very expensive and there are plenty of YouTube videos
describing this problem and repairs. Read more about blend door actuators: A/C blows cold on one side and warm on the other: 2 common reasons
Front O2 sensors:
In the 2009-2010 F-150, the Check Engine light with the codes P0130 - O2 Sensor Circuit Malfunction (Bank 1, Sensor 1) or P0150 O2 Sensor Circuit Malfunction (Bank 2, Sensor 1) can be caused by a bad front (upstream) oxygen sensor.
If confirmed, an oxygen sensor will need to be replaced, which is a fairly simple job. In the 5.4L V8, Bank 1 is on the passenger side, Bank 2 is on the driver side. Sensor 1 is the one that is closer to the engine, before the catalytic converter.
Exhaust manifold leaks:
The exhaust manifold leak is noticeable when the truck is started cold. It sounds like a loud ticking noise from the engine bay that disappears once the exhaust manifold warms up. The leak could be caused by a crack in the manifold, broken manifold studs (often the ones closer to the back) or a failed manifold gasket.
The typical repair includes replacing the studs and gaskets and, if needed, the exhaust manifold itself. It's not a fun job, here is a good video
showing the repair. In a shop, this job may cost up to 6.4 hours of labor (for the passenger side, 5.4L V8) plus the parts.
Transmission fluid leak (6-speed 6R80 transmission):
Many owners report that the transmission fluid leak was originating from the electrical plug of the transmission (bulk head connector sleeve) on the rear passenger side of the transmission. Replacing the sleeve involves removing the transmission pan and draining the fluid.
It's a good idea to change the transmission fluid filter and clean the magnet in the transmission pan at the same time. Ford issued the TSB 14-0069 for this issue. Watch this video
explaining the problem and repair.
Ford issued a few TSBs for various transmission concerns (e.g. harsh downshift) that advised reprogramming the transmission control module (TCM) and possibly powertrain control module or PCM (e.g. TSBs 11-8-12, 13-11-3) as a solution. For any concerns with the transmission shifting, it makes sense to check with a local Ford dealer if the TCM or PCM can be re-programmed with the latest software first.
The key is to catch a coolant leak or a low coolant level before it can cause the engine to overheat. Signs of leaks include a dropping coolant level, drops on the driveway and a smell of coolant from the engine compartment.
One of the common sources of leaks is a crack in the coolant overflow tank. Replacing an overflow tank is not difficult and the part is not very expensive.
In the Coyote V8, the quick-connect spots at the "Y" coolant outlet and at the top radiator hose are known to leak. This is also a fairly easy repair. Watch these videos
A leaking water pump is also not uncommon. Replacing a water pump in the 5.0L V8 will cost 1.7-2.0 hours of labor (2.3-2.8 hours for the 3.5L V6) plus the part and extra coolant.
If the leak is not obvious, the cooling system will need to be pressure tested to find it.
Water leaks in the cab:
We found many reports of water leaking into the cab causing stains on the headliner, rust in the lower corners of the cab, rocker panels and other areas. In the long term, water damage can also cause the corrosion of the electric wiring and mold under the carpet.
This means that it's a good idea to check your truck for signs of water leaking into the cab and repair any leaks before they cause problems. Common sources of water leaks are the third brake light, satellite antenna and the rear window seal.
We found many videos
explaining the water leak issues and repairs. If you are looking to buy a used F-150, the areas in the corners of the cab and under rocker panels need to be inspected carefully for rust. Check for stains on the headliner and signs of moisture under the carpet.
Fuse 27 Crank no start:
The Ford TSB 15-0137
describes the problem where the fuse 27 in the battery junction box (fuse box) can overheat and cause starting or stalling problems. According to the TSB, the fuse 27 relocation kit must be installed if there are signs of excessive heat at the fuse 27. Youtube has many videos on this topic.
3.5L EcoBoost V6 sputtering/misfiring on acceleration:
One of the common causes for this issue is the condensation in the turbo intercooler. The intercooler is located in front of the radiator. It cools down the intake air that comes out of the turbochargers before it enters the engine.
What often happens is the crankcase oil vapors and water condensation that accumulate at the bottom of the intercooler can get sucked into the engine on hard acceleration. This can cause sputtering, misfiring, spark plug failures, the Check Engine light and other issues. The catalytic converter can also fail as a result of misfiring. The problem is more pronounced in humid weather.
Ford came out with the TSB TSB 13-8-1 that, following the diagnostic procedure, advises removing the top air deflector and installing the bottom air deflector on the intercooler, as well as reprogramming of the PCM.

Youtubers suggest several different 'use at your own risk' type fixes (not approved by Ford) from installing aftermarket oil separators (catch cans) into the PCV system to cleaning the sensors in the intake system. Search Youtube for '3.5L Ford EcoBoost shudder on acceleration'.
Spark plugs if they are fouled/cracked or worn, can also cause misfiring and may need to be checked. Many owners report that replacing spark plugs fixed the misfiring. Some owners mentioned that ignition coils had to be replaced too. In general, spark plugs in a turbocharged engine fail more often.
Electric vacuum pump (EVP) problems in the 3.5L EcoBoost:
2010 Ford F-150.
According to the bulletin TSB 15-0105, "some 2011-2012 F-150 vehicles equipped with a 3.5L gasoline turbocharged direct injection (GTDI) engine may exhibit a hard brake pedal on initial start-up, an electric vacuum pump that is inoperative or excessively noisy and/or fuse F64 is open in the battery junction box (BJB)"
. The bulletin describes the diagnostics and repair.
Another Ford bulletin 15N05 – Electric Vacuum Pump Extended Coverage for the 2011-2012 F150, extended the warranty for the electric vacuum pump to 10 years of service or 150,000 miles. The electric vacuum pump is located in the left front portion of the vehicle. There are plenty of videos on Youtube describing the problem and the repair.

F-150 Engine choices:
Modular 4.6L and 5.4L V8, 2009-2010 F-150:
The 248-hp 4.6L 2-valve V8 ("W" in the 8-th position of the VIN), the 292-hp 4.6L 3-valve V8 ("8" in the 8-th position of the VIN) and the 320-hp 5.4L 3-valve V8 (The 8-th digit of the VIN is "V") are simple modular V8 motors with single overhead cams driven by timing chains. The 3-valve 4.6L and the 3-valve 5.4L V8 are also equipped with variable camshaft timing (VCT) system.
Regular oil changes are the key to the longevity of the Triton V8, as many engine problems are caused by a lack of lubrication. Another important point is not to ignore engine noises. If a problem is caught early, the repair will be less expensive. Here is the Youtube video
explaining the 5.4L engine noises from a technical view. Overall, all three engines can last for up to 300,000 miles with regular maintenance.
3.7L Duratec V6 (2011-2014 F-150):
The 3.7L 302-hp 4-valve Ti-VCT (Duratec) V6 (The letter "M" in the 8-th position of the VIN) is a good choice if you don't need the extra power. It's a long-lasting, simple DOHC engine with a conventional multi-port fuel injection. It is used in many Ford/Lincoln/Mazda vehicles.
Unlike in other applications, in the F-150, the water pump in this engine is built externally, which makes it easier to service. It's also the most fuel-efficient engine for the 12-th gen. F-150: the 2011-2014 2WD F-150 with the 3.7L V6 is rated at 17/23 mpg
3.5L EcoBoost V6:
(The 8-th digit of the VIN is "T") It's a modern twin-cam V6 engine with a direct injection and two turbochargers (one for each bank).
In the long run, the EcoBoost will be more expensive in repairs, but it's a blast to drive. It offers plenty of power and torque at lower RPMs compared to the Coyote V8.
Turbocharged engines in general are more sensitive to a lack of maintenance or the quality of engine oil. Spark plugs will need to be replaced more often. The timing chain may also need to be changed at higher mileage.
5.0L Coyote V8
("F" in the 8-th position of the VIN) is the best all-around choice if you need the V8 power. It's a solid, no-nonsense, naturally-aspirated DOHC V8 with a conventional multi-port fuel injection.
If you can keep it from overheating and do your regular oil changes in time, it will last long, but watch out for coolant leaks. The 2011-2014 F150 4WD with the 5.0L V8 is rated at 14/19 mpg
6.2L 2-valve V8:
Ford F-150 SVT Raptor.
The 411-hp beast is a SOHC V8 that is available in the 2010-2014 F-150 SVT Raptor. Although it's rare on the used car market, the Raptor will turn heads. The 6.2L V8 (the 8-th digit of the VIN is "6") is similar in design to the 4.6L/5.4L engines.
It has a cast iron block and offers 434 lb. ft. of torque. With all kinds of mods available for this truck, it's a good long-term performance project, if you don't care about the gas mileage. Changing the oil regularly and keeping the coolant at the proper level will insure the longevity of this engine.
What to look for when buying a used Ford F-150:
In our view, the 5.0L V8 is the best overall choice if you need more power, while the 3.7L V6 will work well for basic needs, given the high gas prices. When checking a used F-150, it helps if you can start the engine when it's cold to see if the timing chain rattles (especially in the 3.5L EcoBoost) or if the exhaust manifold is leaking.
Check the service records to see if the spark plugs have been replaced and if the oil changes were done on time. Have the truck carefully inspected by an independent mechanic to check for mechanical issues such as broken leaf springs, a separated driveshaft hanger bearing, leaks, etc. Make sure to test all 4WD modes. Overall, the F-150 is a great truck but it needs to be well maintained to last. We found an informative Maintenance FAQ
