Some 2007-2016 Edge/MKX/Flex/MKT/MKZ/MKS/Taurus/Police Interceptor Sedan/Explorer/Police Interceptor Utility vehicles equipped with AWD and built on or before 30-Jun-2016 may exhibit a propane or natural gas odor during idle or low speed driving. This may be due to break down of the power transfer unit (PTU) fluid caused by excessive heat. If the source of the odor is identified as originating from the PTU, an idler bearing repair kit is available to repair the PTU. Refer to the Workshop Manual (WSM), Section 308-07. If the PTU is determined to be repairable, utilize kit GB5Z-7P258-A and the included instruction sheet. For claiming use causal part 7P258 and applicable labor operations in sec

When does it fail?
Of the 40 engine complaints filed for the 2010 Ford Edge, here's the actual mileage breakdown — failures cluster heaviest at 0-25,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
Owners have filed 40 engine complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA engine complaint has been filed on this vehicle in over 10 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
The Powertrain Control/Emissions Diagnosis (PC/ED) manual has been revised for diagnosing electronic throttle bodies (ETBs). The ETC_ACT and ETC_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes (DTCs) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer to historical DTCs and the PC/ED, Section 3 No DTCs Present Index chart for further information.

The failure pattern owners describe
The dominant failure across these 40 complaints is the internal water pump on the 3.5L Duratec engine. Owners describe the pump failing without warning—no dashboard lights, no temperature alerts, no prior symptoms. Once it fails, coolant leaks directly into the engine oil within minutes, leading to catastrophic engine damage. Owners report loss of all engine power at highway speed, temperatures spiking suddenly with no gauge warning beforehand, and in several cases, total engine failure requiring replacement at costs ranging from $4,700 to $9,000. The water pump location inside the engine means a simple part failure triggers complete engine destruction; some owners note the repair itself requires 13+ hours of labor due to the design. Several complaints reference a known class-action lawsuit and mention Ford's awareness of the defect, yet owners report no recalls, no proactive dealer warnings, and no manufacturer assistance. A secondary pattern involves sudden acceleration or uncontrolled RPM surges (jumping from 1500 to 3500 RPM), occurring both at idle and during driving, with one crash reported. Dealerships have told owners this behavior is "normal" and refused to fix it. Stalling at idle and during shifts has also been reported, sometimes with check engine lights, sometimes without. One complaint involved smoke and fire. Oil and transmission fluid leaks onto the exhaust, creating burning odors and toxic fumes, and there is one report of antifreeze odor from the heater core.

Failure modes owners describe
Internal water pump failure
Water pump located inside the 3.5L Duratec engine fails suddenly without warning. Coolant leaks into the engine oil, contaminating it and destroying the engine within minutes to hours.
When: Failure reported between 38,000 and 242,000 miles; commonly between 65,000–170,000 miles
Symptoms owners cite: No warning lights on dashboard; No temperature gauge warning before failure; Sudden loss of engine power at highway or city speeds; Temperature gauge spikes after stall occurs; Engine shuts down completely; Coolant leaking visibly from engine; Oil appears milky/discolored (coolant in oil); Antifreeze smell (in one case, from heater core)
Codes mentioned: Check engine light (in some cases, but not all), Engine overheat detected on diagnostic equipment
Repairs/costs cited: Water pump replacement alone is a simple $500 job, but this internal design requires engine disassembly. Labor intensive (13+ hours), parts under $200, but total repair cost $1,200–$9,000. In many cases, engine replacement required due to coolant/oil contamination destroying internal components. Oil change and coolant system flush also needed.
Recalls/TSBs owners mention: Class-action lawsuit filed against Ford for defective water pumps (referenced by multiple owners). No recalls identified by owners. Dealerships reported unable to guarantee engine integrity even after pump replacement. Manufacturer contacted but offered no assistance in most cases. Some owners reference Ford's known awareness of the issue but refusal to act.
Sudden acceleration and uncontrolled RPM surges
Vehicle accelerates unexpectedly without driver input, or RPM jumps from idle (1500) to high RPM (3500) without corresponding wheel acceleration. In one case, caused crash into garage and tree.
When: Reported at low speed (5–10 mph in driveway, 20–30 mph on roads) and at highway speed. One owner reported 2–3 episodes in the month before catastrophic incident.
Symptoms owners cite: Sudden acceleration with no pedal input; RPM gauge jumps from ~1500 to ~3500 RPM; Slight jerk or surge in the vehicle; RPM returns to normal within seconds on its own; Occurs both at idle and while driving; Occurs even with cruise control engaged; Vehicle difficult or impossible to control during event
Codes mentioned: Error messages on diagnostic scanner (owner reported but specific codes not stated)
Repairs/costs cited: Dealerships told owners 'this is normal for this vehicle' and refused to repair. One owner reported damaged hood at dealer during inspection. No repair costs documented; issues remained unresolved.
Recalls/TSBs owners mention: Ford customer relations promised response within 3 business days but did not respond. Dealerships refused to acknowledge defect; owner stated issue is similar across thousands of cases.
Engine stalling at idle, during shift, and in turns
Engine stalls unexpectedly while stationary, shifting from park to drive, accelerating from stop, or during slow turns. Occurs repeatedly over short periods or intermittently over months.
When: Reported at very low mileage (4,500–14,000 miles) and higher mileage (120,000+ miles). One pattern involved stalling after slow turns on 4 separate occasions over months.
Symptoms owners cite: Engine stalls without warning; Loss of power steering and electrical power; Engine will not restart immediately; requires waiting 35–55 minutes or longer; AC running correlates with stalling in one case; Stalling occurs repeatedly in short timeframes (7 occurrences in couple hours reported)
Codes mentioned: Check engine light (mentioned in some complaints), Wrench light (indicates electronic throttle body issues per owner's mechanic)
Repairs/costs cited: One owner cited recall for idle controller with backorder until end of September. Throttle body replacement cost $691.03 in one case. Dealerships unable to recreate stalling during diagnostic in multiple cases and reported 'no trouble found.'
Recalls/TSBs owners mention: Recall issued for idle controller (mentioned in narratives as backorder). No other manufacturer action documented. One dealer stated this is a known issue and advised owner to keep receipt for future recall.
Complete engine shutdown at highway speed
Engine loses all power suddenly while driving at highway speeds (45–70 mph) with no prior warning. Vehicle becomes impossible to restart or restart after delay. Loss of power steering and all electrical systems.
When: Reported across multiple mileages, from 150,000 to 242,000 miles
Symptoms owners cite: Abrupt loss of all engine power; No warning lights illuminated before failure; All gauges go dark; No hazard lights function; Engine will not restart (in several cases); Smoke from under hood (in one case); Loud pop heard before stall (in one case)
Codes mentioned: Check engine light (in one case)
Repairs/costs cited: Vehicles towed to dealers and Ford specialists. In one case, dealer test-drove 200 miles with Ford engineer specialist and could not duplicate problem or identify cause; vehicle returned without repair. No repair cost documented because repairs were not completed in most cases.
Recalls/TSBs owners mention: Manufacturer referred one owner to NHTSA Hotline. Dealership offered diagnostic test in another case but owner declined. No repairs completed; vehicles returned to owners or left at dealers.
Engine fire
Vehicle caught fire while driving at low speed.
When: At 72,000 miles
Symptoms owners cite: Smoke coming from under the hood; Vehicle caught fire
Repairs/costs cited: Fire department extinguished the fire. Vehicle was destroyed and towed to impound lot. Police report filed.
Oil and transmission fluid leaks onto exhaust
Oil or transmission fluid leaks from PTU (power transfer unit) or transmission seals onto the muffler and exhaust pipe, burning and creating toxic fumes that enter the cabin through the fresh air intake system.
When: Complaint filed for 2008 Edge; unclear if issue applies to 2010 model year
Symptoms owners cite: Strong burning odor inside vehicle; Toxic fumes entering cabin; Owner experienced nausea/sickness from fumes; Oil visible dripping onto ground when parked; Burning smell when driving
Repairs/costs cited: Ford dealership attempted repair with updated seals; issue described as persisting. No cost documented.
Recalls/TSBs owners mention: Dealership attempted repair with updated seals
Antifreeze odor from heating system
Strong antifreeze smell coming from the heater when heat is on, indicating a small coolant leak in the heater core or related heating components.
When: Noticed immediately after purchase; complaint on new vehicle
Symptoms owners cite: Strong antifreeze odor from heating vents; Odor very noticeable when engine is cold; Odor comes and goes throughout the day; Requires cracking window or opening sunroof to tolerate driving
Repairs/costs cited: Dealerships (two visited) unable to find any problem. Owner (35-year mechanic) suspects heater core leak.
Engine hesitation, rough idle, and throttle body issues
Engine runs rough, hesitates, or fails to respond smoothly to throttle input. One owner reported gasoline smell correlating with hesitation.
When: Reported at low mileage (4,500 miles, 38,153 miles)
Symptoms owners cite: Engine hesitates; Rough idle; Check engine light illuminates; Gasoline smell from engine bay; Engine shaking at speed
Codes mentioned: Check engine light
Repairs/costs cited: Throttle body replacement cost $691.03. Torque converter also replaced under warranty in one case. Service person told owner this is a very common problem; advised to keep receipt for future recall.
