The throttle body is the dominant failure. Owners describe engine power cutting out mid-highway at speeds above 60 mph with no warning—the wrench light comes on, acceleration vanishes, and the vehicle enters limp mode. The engine stays running but won't respond to the pedal. Most owners manage to coast to safety, shut the engine off, wait a few minutes, restart it, and drive on. This cycle repeats days or weeks later, sometimes multiple times in one trip. Dealerships consistently identified the throttle body as the culprit, but the part sat on nationwide back order for 3 to 5 weeks—some owners waited into October or longer. Repair costs run $300–$520 out of warranty, and dealers typically offered no loaner. A few owners report Ford was aware of the defect.
Fuel system failures run a close second: vapor leaks causing check engine lights (code P0456), fuel spilling during fill, and fuel filler necks requiring replacement. One owner had the vent valve fail, fuel the canister, and then face the prospect of a whole fuel tank replacement. The recall (16V777000) was issued late, and dealers reported parts unavailable as of 2016 with no confirmed delivery date.
Rough idle, stalling at stops, and RPM drops rounded out the complaints. Throttle body cleaning sometimes helped briefly but didn't fix the root cause. Dealers occasionally could not diagnose the issue despite multiple visits.
Failure modes owners describe
Throttle Body Malfunction / Power Loss
Engine loses power or enters limp mode during driving, causing sudden deceleration or complete loss of acceleration response despite engine still running. Wrench light illuminates; power often returns after turning engine off and restarting, but the failure recurs.
When: 2012–2014, typically above 70,000 miles or within 3–4 years of ownership; occurs without warning during highway or city driving
Symptoms owners cite: Loss of engine power despite engine running; No response to accelerator pedal; Sudden deceleration; Wrench light (powertrain/throttle control) illumination; Check engine light (often code P2111 or P2112 - throttle actuator control system); Vehicle enters limp mode; Power returns after engine off/restart cycle, but fails again shortly after
Codes mentioned: P2111, P2112, Throttle actuator control system fault
Repairs/costs cited: Throttle body replacement required. Parts were on nationwide back order for weeks to months (reports cite 3–5 weeks, some longer); repair cost $300–$520 out of warranty; some owners paid diagnostic fees ($50–$92) before diagnosis confirmed.
Recalls/TSBs owners mention: Ford aware of the defect per owner reports; throttle body parts heavily back-ordered; no recall issued despite numerous complaints and safety hazard; dealers offered no loaner vehicles during repair delays; extended warranties did not cover the part in most cases.
Fuel Filler Neck / Fuel Tank Vapor System Leak
Fuel vapor leaks or fuel spills during refueling; fuel filler door may not open; check engine light illuminates with vapor leak code. Related components (fuel filler pipe, vapor solenoid valve, vent valve) fail and require replacement. Some owners report gas pump shutoff problems and inability to fill tank properly.
When: Reported across a wide range of mileages (57,000–119,000 miles); some owners experienced recurring leaks after repair
Symptoms owners cite: Fuel vapor smell; Fuel spilling or spraying out of filler pipe during refueling; Fuel leaking from rear driver-side area near wheel; Check engine light with vapor leak code (P0456); Fuel pump shutoff during fill (as if tank is full when empty); Difficulty refueling; Fuel filler door stuck or difficult to open; Bad gas mileage (in one case linked to vent valve full of fuel and failed canister)
Codes mentioned: P0456, Fuel system vapor leak code
Repairs/costs cited: Fuel filler neck replacement ($750–$931); vent valve replacement (failed and recurred 2 weeks later in one case); charcoal canister replacement; fuel pump replacement ($1800 quoted in one case); smoke test performed to identify leak paths.
Recalls/TSBs owners mention: Recall NHTSA 16V777000 issued for fuel system, but parts unavailable for extended periods (dealers reported parts on national back order as of late 2016, with no ETA); owners not eligible for recall were denied coverage; manufacturer did not assist with rental or repair costs.
Rough Running / Rough Idle / Stalling at Stop
Engine runs rough when accelerating (especially on inclines), sputters, or stalls at stop lights/signs. RPM fluctuations or drops; check engine light may come on and off intermittently. Some incidents involve multiple stalls in short succession.
When: Intermittent; reported 2013–2014 timeframe; can occur at any mileage
Symptoms owners cite: Engine running rough during acceleration; RPM fluctuations or rapid RPM drops; Engine sputtering; Stalling at stop lights or stop signs; Stalling during turns or low-speed maneuvers; Multiple stalls in one trip (one owner reported 3 stalls in 30 minutes); Check engine light comes on/off intermittently; Wrench light may appear; Engine hesitates to start after stall
Codes mentioned: Check engine light (intermittent, codes not always persistent)
Repairs/costs cited: In some cases, throttle body cleaning temporarily resolved the issue but failure recurred; canister purge valve replacement ($390 suggested, but not the root cause in at least one case); multiple visits to dealership with no resolution in some instances.
Recalls/TSBs owners mention: Dealers could not diagnose the problem in some cases (reported 2–3 service visits with no resolution); some owners received no clear answer and were told 'nothing was mechanically wrong' despite persistent failures.
