2011 Ford F-150 Problems

Updated Differential Clutch Kit Available if Rear End Noise is Heard

If a noise from the rear end is heard when going around turns or after driving at highway speed for an extended period, this could be caused by a failing differential clutch kit. An updated differential clutch kit available.

A/C Fan Speed Changing Constantly

The 2009-2014 Ford F-150 with automatic climate control may have a problem with frequent fan speed changes when using the heater or air conditioner. This includes F150 Harley Davidson, King Ranch, SVT Raptor, FX2, FX4, Platinum, Lariat, and STX editions. 

Normally, the fan speed changes only to maintain a selected temperature, but when the fan speed changes frequently and needlessly, there is an issue with the fan speed control unit. 

The fan speed control unit, sometimes erroneously called the blower motor resister, regulates the speed for the blower motor in order to maintain the temperature set by the driver. When it fails, the fan will run at random settings, and the climate control will be inaccurate.

Note: this does not affect the temperature of the air that comes from the vents, it affects the amount of air that comes from the vents. 

The repair is simple, and quick. The control unit is located behind the glove box in most models, and removal and installation takes only minutes.

Also note: this only applies to vehicles with single or dual automatic climate control.

Blower Motor Only Works on High

The 2004-2014 Ford F-150 with manual temperature and fan controls may have problems with the the blower motor only blowing air on certain settings. Most commonly the fan will only run on the highest setting. This is a well documented problem, and is caused by a failing blower motor resistor.

Correcting the problem is straight forward, and requires replacement of the small resistor. The resistor is normally found behind the glove box, next to the blower motor.

2011 Ford F-150 Recalls

Automatic Transmission Shifts To First Gear Unexpectedly

The vehicle's automatic transmission may shift unexpectedly and suddenly into first gear while driving, which can result in a loss of vehicle control, sudden slowing of the vehicle and possible transmission damage. Dealers will reprogram the powertrain control module with updated software free of charge to resolve the concern.

Reverse Gear Engagement and/or Lighting Issues

Certain vehicles may have been assembled with a transmission range sensor (TRS) that was calibrated out of specification for reverse gear. If this condition exists, the transmission may not properly engage reverse gear and/or if reverse gear does engage, the "R" indicator on the dash or the backup lamps may not illuminate. These conditions increase the risk of a crash or a pedestrian being struck due to the vehicle's not signaling it is in reverse. Dealers will inspect and replace the transmission range sensor as necessary to correct this concern. The Ford recall number is 12C23.

Shifter May Be Moved Out of Park Without Pressing the Brake Pedal

The brake/shift interlock can fail, allowing the transmission to be shifted into park without depressing the brake pedal. If the transmission were shifted into gear without depressing the brake pedal, a crash or injury to a nearby pedestrian could result. Dealers will inspect the brake shift interlock switch function and replace the switch if necessary.

Bought a 2011 f150 stx with a 3.7 the engine is small but its been good and dependable sofar at 35, 0000. Tows my 6, 000lb boat to and from ramp no problem. As a mechanic myself the 3.7 is easy to repair lots of room to remove a/c compressor, alternator, water pump or front cover if needed. Only complaint Is no cup holders on arm rest, but its not the end of the world
