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 t

The failure pattern owners describe
The 3.5L EcoBoost in these 2011 F-150s has two major recurring problems. First, moisture accumulates in the charge air cooler (intercooler) of the turbo system. When you accelerate hard—passing, merging, or towing—that water gets sucked into the cylinders, causing violent shaking, complete power loss, and limp mode, often in rainy or humid conditions. This has happened to owners at all mileages from 700 miles to 100,000+. The truck shakes, won't accelerate, and then suddenly recovers after a minute. It's happened multiple times per owner, and several have nearly caused accidents because they lost power while passing or merging on interstates. Ford issued technical service bulletins installing a deflector shield on the intercooler, but owners report this fix doesn't work.
Second, the timing chain stretches prematurely. Owners hear a rattling or tapping sound from the front of the engine on cold start (lasting 2–5 seconds), and this noise often signals the chain is wearing out. As the chain continues to wear, the truck loses power, shakes violently, and eventually stalls or fails entirely. Timing chain replacement runs $2,600–$3,400 at a Ford dealer; complete engine replacement costs $10,500–$12,000. Some owners discover the chain has failed catastrophically at highway speeds, which is a serious safety risk. Ford revised the timing chain design in later model years, but owners report Ford refuses to cover the failure outside the 5-year/60,000-mile warranty, even though many vehicles fail well beyond that point under normal highway driving.
Related issues include repeated spark plug and ignition coil failures (owners have replaced plugs three or four times), rough idle that dealers say is "normal," and premature catalytic converter failure from moisture damage. One owner reported Ford eventually refused to work on their truck after seven months of unsuccessful repair attempts for the power-loss issue.

Failure modes owners describe
Intercooler moisture ingestion causing misfire and power loss
Condensation accumulates in the charge air cooler (intercooler) of the 3.5L EcoBoost turbo system. During hard acceleration—particularly in humid or rainy conditions—this water is drawn into the engine cylinders, causing misfires, violent shaking, loss of power, and engine limp mode. Owners report this occurs most frequently when passing, merging, or towing under load.
When: Occurs at various mileages, from as low as 700 miles to 100,000+ miles; triggered by acceleration in humid/rainy weather
Symptoms owners cite: Violent shaking and shuddering during acceleration; Sudden loss of power when pressing accelerator; Engine misfire and limp mode activation; Check engine light flashing or illuminating; RPMs rise but vehicle speed drops; Issue resolves after 1–5 minutes when throttle is released; Repeated occurrences especially after extended cruising at low throttle followed by hard acceleration
Codes mentioned: P0300 (random misfire), P0305 (cylinder 5 misfire), P0430 (catalyst system efficiency below threshold)
Repairs/costs cited: Ford issued TSB 13-8-1 (deflector installation), later TSBs to remove then re-install deflector; owners report deflector fix is ineffective. Coil and spark plug replacement attempted repeatedly by dealers with only temporary relief. Some owners replaced all coils preemptively. Intercooler replacement mentioned in narratives but no permanent fix documented. Repair costs cited around $650–$3,400 depending on work scope.
Recalls/TSBs owners mention: Ford acknowledges the problem via TSBs (TSB 13-8-1, TSB 14-0194, TSB 15-0131, TSB 16-0027) and claims awareness of issue. NHTSA investigation PE13018 was initiated then closed in 2014 after Ford claimed a fix. TSBs installed deflector shields on charge air cooler, later reversed. Owners report Ford customer service refused to work on some vehicles and denied knowledge of issues even as they are widespread.
Timing chain stretch and wear causing rattle, misfire, and catastrophic failure
Premature stretch and wear of the timing chain and guides on the 3.5L EcoBoost engine. Owners report a rattling or tapping noise from the front of the engine at cold start, lasting 2–5 seconds. The condition progresses to check engine lights, loss of power, violent shaking, and in some cases complete engine failure requiring replacement. Owners note that Ford revised timing chain specifications and part numbers on later model years, suggesting the original design was defective.
When: Cold start symptoms begin around 50,000–90,000 miles; catastrophic failures occur between 90,000–170,000 miles in some cases
Symptoms owners cite: Rattling or tapping noise from front/top of engine on cold start; Noise lasts 2–5 seconds after ignition, sometimes longer; Check engine light illumination; Loss of power and rough running; Violent shaking at highway speeds; Engine stalls or enters limp mode; Sludge accumulation in oil despite regular changes; Variable camshaft timing (VCT) unit separation (one case reports projectile through valve cover)
Codes mentioned: Timing chain fault codes, VCT-related codes (in cases of camshaft timing failure)
Repairs/costs cited: Replacement of timing chain, guides, and related components; one owner cited $2,634.44 at Ford dealer. Another cited $3,400 for timing chain work. In severe cases, complete engine replacement quoted at $10,500 to $12,000. VCT unit separation case required valve cover replacement and extensive work.
Recalls/TSBs owners mention: Ford issued multiple TSBs (TSB 14-0194, TSB 15-0131, TSB 16-0027) acknowledging the problem. However, owners report Ford has not initiated a recall or extended warranty coverage beyond the standard 5-year/60,000-mile powertrain warranty. Owners outside warranty are denied coverage. One dealer told owner that Ford engineering 'has no clue how to remedy this issue.'
Engine governor limiting top speed to ~89 mph
The 3.5L EcoBoost engine is electronically governed to limit top speed to approximately 89 mph, ostensibly to protect tire speed ratings. However, Ford does not disclose this governor in the owner's manual or on the vehicle; the speedometer indicates 120 mph. One owner nearly caused an accident when the engine stalled at 89 mph while attempting to pass on an interstate during a dangerous traffic maneuver.
When: Occurs when attempting to exceed 89 mph regardless of conditions
Symptoms owners cite: Engine stalls when approaching 89 mph during acceleration; No indication on speedometer or owner documentation of speed limiter; Loss of power exactly at speed threshold
Repairs/costs cited: No repair; this is a software limitation. Ford acknowledged the governor exists when contacted by owner.
Recalls/TSBs owners mention: Ford confirmed to owner that a governor is present to prevent exceedance of tire speed rating (89 mph) but refused to remove it or modify the speedometer to reflect the actual limit. Ford stated the vehicle came with 113 mph-rated tires, making the 89 mph governor unnecessary. Owner was told 'it's not Ford's place to enforce speed limits.'
Rough idle and variable camshaft timing faults
Owners report persistent rough idle at stoplights and stop signs, particularly on cold start or after extended low-throttle driving. In some cases, the condition is accompanied by rattling and is attributed to variable camshaft timing (VCT) unit malfunction or stretch in the timing chain affecting camshaft positioning.
When: Occurs at idle; rough idle present from early ownership (reported at ~100 miles) and persists; may worsen over time
Symptoms owners cite: Noticeable vibration or miss during idle at stops; Rough running sensation felt throughout vehicle; Cold-start rattle (separate from timing chain noise); Check engine light may appear
Codes mentioned: VCT-related fault codes
Repairs/costs cited: Dealers have been unable to resolve rough idle in several cases. One owner was told by dealership that this is 'just how the vehicle runs' despite multiple customer complaints. In one case, rough idle was part of a larger VCT unit failure that required extensive repairs.
Recalls/TSBs owners mention: No recalls or service bulletins specifically for rough idle have been issued. Dealers state they have no updates and cannot address the concern if diagnostic codes are not present.
Exhaust manifold warping and heat-related failure
The driver's side exhaust manifold warps under high heat, causing a gap at the rear end and producing a rapid chirping sound, especially during load and hill climbing. The problem is attributed to the extreme heat generated by the turbocharger and engine under sustained high-load conditions (e.g., towing heavy trailers over mountain passes).
When: Begins around 135,000 miles with sustained towing loads; worsens over a year of operation
Symptoms owners cite: Rapid chirping sound from engine during acceleration, hill climbing, or cold start; Noise increases with engine load (downshifting, towing); Diminishes slightly after warm-up but does not disappear
Repairs/costs cited: Tightening bolts provides temporary relief but does not resolve the issue. Permanent fix requires exhaust manifold replacement. Aftermarket manifolds of superior design and construction have been suggested by others online as a solution to prevent recurrence.
Spark plug and ignition coil failures
Owners report repeated premature failures of spark plugs (cracking, fouling, burning out) and ignition coils, often within weeks of replacement. Multiple replacements are required at owner expense even under warranty in some cases. Pattern suggests the root cause is moisture ingestion or another underlying ignition system defect rather than maintenance issues.
When: First failures reported around 20,000–50,000 miles; repeated failures continue through 110,000+ miles
Symptoms owners cite: Misfire codes (P0300, P0305, etc.); Check engine light illumination; Engine shaking and loss of power; Cracked or fouled spark plugs on removal; Bad ignition coils on diagnosis
Codes mentioned: P0300 (random misfire), P0305 (cylinder 5 misfire), Cylinder-specific misfire codes (P0301–P0306)
Repairs/costs cited: Spark plugs replaced multiple times at owner cost in many cases ($400+ for full set with coils); coils replaced under warranty in some instances. Owners report replacing plugs 3–4 times and all six coils preemptively to avoid repeat failures. Root cause not addressed by replacements alone.
Recalls/TSBs owners mention: Ford initially offered warranty coverage on coil replacement in some cases but charged diagnostic fees and $100 deductibles. As vehicles moved out of warranty, owners were told to pay out-of-pocket. Ford has not addressed the underlying cause of premature spark plug and coil failure.
Loss of power and brake engagement during acceleration
In rare cases, owners report sudden complete loss of power during acceleration accompanied by apparent automatic brake engagement, causing the truck to decelerate abruptly and the brakes to lock hard, screeching the tires. One owner reported this happened while crossing a rural highway with a dump truck approaching.
When: Sporadic occurrence; one owner reported it happening at least 3 times over several months
Symptoms owners cite: Sudden loss of acceleration response even with throttle fully pressed; Apparent automatic brake engagement; Tires lock and screech; Vehicle decelerates dramatically; Truck limps or barely accelerates after incident
Repairs/costs cited: One owner reported that after multiple repair attempts over 7+ months (including intercooler replacement), Ford eventually denied the problem existed and stated they would not work on the truck at all. No repairs succeeded.
Recalls/TSBs owners mention: Ford denied that the issue has occurred in other trucks and claimed they were aware of no such problem. After repeated complaint, Ford refused to attempt repairs and stated they are 'not allowed to try to repair these trucks at all' (regarding this specific failure mode).
Catalytic converter premature failure and fouling
Catalytic converters fail prematurely, particularly on the driver side (Bank One). Some failures occur within the first 50,000 miles. The failures are attributed to moisture and oil contamination from the intercooler condensation issue, which causes unburned fuel and water to pass through the exhaust and damage the converter. Multiple converter replacements may be needed.
When: First failures around 20,000–56,000 miles; repeat failures possible
Symptoms owners cite: Check engine light for catalyst system efficiency (P0430); Loss of power related to converter failure; Multiple converter replacements required over vehicle lifetime
Codes mentioned: P0430 (catalyst system efficiency below threshold)
Repairs/costs cited: Catalytic converter replacement on driver side (Bank One) cited in several narratives; cost not always specified but implied to be several hundred dollars per converter. One owner reports two converter replacements.
