Some 2011-2024 Mustang and F-150 vehicles equipped with a 5.0L engine may exhibit a tick tap and/or typewriter ticking noise at idle after an engine oil change. It is often referred to as typewriter noise because of its similarity to the sound of a mechanical typewriter. The noise in question may be heard on some engines when engine temperatures reach 150°F (65°C) or higher and engine speed is at idle up to approximately 1700 RPM. It can typically be heard at the front wheel well and is often isolated to the transmission bell housing or oil pan area. The typewriter noise tick rate can be faster or slower and is not detrimental to the engine function or durability and has no short or long term effects on the engine. This an operating characteristic of the 5.0L engine and no repairs should be attempted.

For 2000-2024 Ford and Lincoln vehicles, swapping a module from a vehicle for diagnosis purposes is likely to cause errors and is not recommended. It is also not recommended to order a replacement module using a vehicle identification number (VIN) from a different vehicle. Most modules on these affected vehicles are VIN/vehicle specific and hardware variations between modules do exist. Swapping a module from a vehicle or ordering a module using a different vehicle/VIN can cause ineffective repairs and additional vehicle down time. Make sure all appropriate Workshop Manual (WSM) procedures are followed when diagnosing the condition prior to all module replacements and only order modules using the correct VIN.

The propellant in certain Takata airbag inflators can experience an alteration over time with exposure to certain climate conditions. A combination of time, high temperature fluctuations, and humidity contribute to the degradation of the propellant in the inflators. This degradation can cause the propellant to burn too quickly, creating high pressure inside the inflator, and in extreme cases causing the inflator to rupture in the event of a crash necessitating airbag deployment. A ruptured inflator can send inflator parts toward vehicle occupants resulting in serious injury or death. Additional information regarding Takata recalls can be found at www.nhtsa.gov and www.safercar.gov.

Some 2010-2020 vehicles may exhibit distorted glass with a subtle orange peel pattern or streaking etched into the surface. This is caused by hydrofluoric acid which is used in some car wash solutions as a cleaning agent. Hydrofluoric acid can attack the glass and cause visual distortion and/or discoloration on the outer surface which cannot be removed by further cleaning. If this type of distortion is found, inspect the area of the glass that is covered by the cowl and/or molding.

On vehicles equipped with an automatic transmission it is imperative that the converter pilot hub be greased with Motorcraft Multi-Purpose Grease Spray XL-5-A even if grease was not applied from the factory. Also verify that the engine/transmission alignment dowel pins are present as well as the engine crankshaft dowel pin, if equipped, when installing the transmission. Failure to adequately lubricate the converter hub greatly increases the likelihood of the flexplate cracking in the future. Missing dowels may cause a misalignment issue also resulting in a premature failure. Refer to Workshop Manual (WSM), Section 307-01.

04 / Agency investigations

Official inquiries.

An investigation is an inquiry into a potential concern. Its presence does not establish a defect, and a closed case does not certify a car’s condition.

Opened Aug 3, 2011 ClosedInability to shift gears on accelerationPE11024

The Office of Defects Investigations (ODI) analyzed complaint data provided by Ford as well as complaints submitted to ODI from consumers.In total, there were 364 unique reports indicating various shift quality issues while driving.Ford identified several factors that may contribute to shift quality concerns in the subject vehicles, including cold transmission, clutch stay-out at high engine speeds, gear clash or grinding, and gradual loosening of clutch plate bolts in some early production vehicles.The largest percentage of complaints indicated higher than expected shift efforts in cold ambient temperatures.These complaints were related to transmission fluid viscosity and the higher shift efforts resolved themselves with the drivetrain warming.Ford published technical service bulletin TSB 11-3-18 to inform technicians that a lower viscosity fluid was available for use to address the cold shift issues.The clutch stay-out condition typically occurs at engine speeds greater than 4000 rpm.It does not prevent the selection of any gear, but may delay clutch re-engagement depending on how long the driver maintains the higher engine speed.Ford identified rotating inertia of the clutch components as the root cause and replacement clutch pedal parts were made available under Ford TSB 10-19-4.A number of reports alleged increasing difficulty selecting gears along with gear clash or grinding.Grinding or notchy gear shifts may be caused by gradual loosening of clutch plate fasteners, which is promoted by certain aggressive shifting.This condition is progressive in nature and initially results in symptoms related to shift quality/feel.Clutch plate bolt loosening will not result in inability to select any gear unless the progressive symptoms are ignored until complete clutch failure occurs.ODI?s analysis identified only five complaints alleging an inability to shift into gear due to loose clutch plate bolts.None of these resulted in a stall and gear shifting could occur before engine start.A revised fastener was designed and implemented in production and is available for service through a special service message.There is no indication of loss of motive power or unreasonable safety risk associated with the alleged defect in the subject vehicles.This preliminary evaluation is closed.
