What stands out
Owners have filed 142 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.
Engine accounts for 20% of all owner complaints filed against this vehicle, across 11 categories tracked.
The failure pattern owners describe
Buyer takeaway: The 2015 Ford Edge has two critical engine issues: sudden loss of power while driving (throttle body or software-related, hard to diagnose) and coolant intrusion into cylinders causing catastrophic engine failure at 70,000–110,000 miles. Both are serious safety hazards with limited factory support and expensive repairs ($6,500–$9,600 for engine replacement).
Owners describe two distinct engine problems occurring across the 2015 Edge fleet. The first is sudden loss of engine power while driving—the engine dies with no warning, typically showing only a "Full Accessory Power Active" message on the dash and a flashing green start button. No check engine light comes on beforehand. This stalling happens at low speeds, intersections, and even on freeways, creating serious collision risk. Owners report that restarting the vehicle is often possible only after shifting into Park. Dealerships struggle to reproduce the problem and blame lack of fault codes. Some throttle body replacements have worked; Ford issued TSB 15-0123 for PCM software updates, but owners report the fix is temporary or ineffective.
The second major failure is coolant intrusion into engine cylinders, causing misfires and complete engine seizure. Owners notice check engine lights, white smoke from exhaust, rough idle, and coolant disappearing with no visible leak. The milky sludge in the oil tells the real story: coolant is mixing with engine oil and destroying internal components. Engine replacement is the only fix, costing $6,500–$9,600. This failure strikes between 38,000 and 199,000 miles but clusters around 70,000–110,000. Ford issued technical service bulletins (TSB 19-2208, TSB 19-2346) but has not issued a recall. Owners report being turned away under warranty exclusions or told their VIN is not covered.
Additional reported failures include loud engine noise and vibration, flex plate cracking, burning smells and fire risk, exhaust fumes entering the cabin, and oil leaks. Dealership response is often dismissive—inability to duplicate problems, refusal to attempt repairs without live fault codes, and referrals to NHTSA when warranty expires.

Failure modes owners describe
Sudden loss of engine power while driving
Engine cuts out without warning during acceleration or normal driving. Owner receives 'Full Accessory Power Active' message on dash and flashing green start button. No check engine light typically illuminates beforehand. Vehicle requires restart—sometimes only possible after shifting to Park.
When: Reported from 2,000 to 9,000 miles; occurs intermittently at low speeds, intersections, freeway ramps, and during turns
Symptoms owners cite: Engine dies with no throttle response even when pedal pressed to floor; Green flashing light on start button; 'Full Accessory Power Active' or similar message displayed; No check engine light in most instances; Radio and dash lights remain functional; Vehicle restarts after sitting briefly or shifting to Park
Repairs/costs cited: Throttle body replacement reported successful in several cases; TSB 15-0123 PCM recalibration attempted but did not prevent recurrence in at least one case. One owner reported fuel pump issues mentioned but not confirmed by dealer.
Recalls/TSBs owners mention: TSB 15-0123 issued 08/10/2015 for PCM software update. Dealerships unable to duplicate problem and cite lack of fault codes as barrier to repair. Buyback requests refused.
Coolant intrusion into engine cylinders
Coolant leaks from engine head gasket or internal water pump into cylinders, causing misfires and catastrophic engine failure. Owners report milky sludge in oil, excessive coolant consumption, and multiple cylinder misfires. Failure typically results in complete engine replacement at $6,500–$9,600.
When: Reported at mileages ranging from 38,000 to 199,000 miles; most commonly 70,000–110,000 miles
Symptoms owners cite: Check engine light illuminates and may flash; Engine misfires in specific cylinders (commonly #1, #2, #3, #4); White or gray smoke from exhaust; Rough idle and hesitation under acceleration; Coolant level drops rapidly with no external leak visible; Rough running, vibration, knocking sounds from engine; White milky residue on oil cap/dipstick (oil contaminated with coolant); Engine overheating warning; Loss of power and limp-mode operation
Codes mentioned: P0301 (random misfire), P0316 (misfire detected in first 1,000 revolutions), P0304 (cylinder #4 misfire), P0303 (cylinder #3 misfire)
Repairs/costs cited: Engine long-block replacement required; parts replaced include long block assembly, spark plugs, water pump, reservoir, oil, oil filter, damaged EVAP line, ignition coils. Costs range $6,500–$9,600. Spark plug replacement alone does not resolve issue; failure recurs.
Recalls/TSBs owners mention: TSB 19-2208 and TSB 19-2346 issued but only as service bulletins, not recalls. Some owners report dealer assistance with cost in isolated cases. Most owners told vehicle is out of warranty or VIN not covered. Class action lawsuit noted (Miller et al. vs. Ford Motor Company).
Engine stalling with accessory power message
Engine stalls intermittently during driving or at stops. Display shows 'Full Accessory Power Active' or 'Power Accessories Off' message. Occurs without prior warning lights. Vehicle may not restart while in Drive; requires shifting to Park.
When: Early in ownership (under 3,000 miles); reported up to 9 months after purchase; can recur despite repairs
Symptoms owners cite: Complete engine shutdown while driving; 'Full Accessory Power Active' message on display; Green flashing start button; Radio continues to work; Vehicle will not accelerate despite pedal input; Stalling at stop lights, intersections, during turns, or in parking lots; Stalling while in traffic, construction zones, or on freeways
Repairs/costs cited: PCM software recalibration via TSB 15-0123 attempted; throttle body replacement performed in some cases. One owner reported stalling persisted less than 24 hours after throttle body replacement.
Recalls/TSBs owners mention: TSB 15-0123 PCM recalibration issued 08/10/2015. Dealerships report inability to duplicate problem, making diagnosis and repair difficult. Some dealerships aware of the issue; others dismissive.
Loud engine noise and vibration
Owner reports loud raring-up or knocking noise from engine, especially when in Park or during acceleration. Noise becomes progressively worse. Cooling fan replacement does not resolve issue.
When: Approximately 11 months after purchase (February 2016); one report at 62,795 miles with loud thumping
Symptoms owners cite: Loud raring or revving sound from engine; Knocking or thumping noise from engine compartment; Noise louder when in Park; Vibration while driving; Noise persists after cooling fan replacement
Repairs/costs cited: Cooling fan replacement performed but did not resolve issue. Owner provided videos to Ford and dealership documenting problem before and after repair with no resolution.
Recalls/TSBs owners mention: Initial dealership assessment that noise is 'normal.' After second visit, cooling fan blamed and replaced. Ford referred to district manager; Ford technician inspection requested but delayed (over 17 days pending as of report date).
Flex plate/flywheel failure
Flex plate cracks or breaks, causing loud clanging noise on startup and abnormal engine behavior. One owner reported flex plate cracked in four places and nearly fell apart.
When: Reported at 110,000 miles; one mention of issue related to short block design affecting multiple model years
Symptoms owners cite: Loud clanging noise on engine startup; Abnormal rattling sound from engine compartment; Vehicle drives abnormally; Engine vibration
Repairs/costs cited: Flex plate replacement cost $5,500 in one case. One owner noted cracked flex plate in four places; mechanic stated this was abnormal wear pattern. Linked to short block design defect.
Recalls/TSBs owners mention: Recall 22-0012 issued in October 2022 for flex plate issue; one owner paid out of pocket in March 2022 before recall, then recall became available but dealer did not honor prior repair.
Engine fire risk and burning smell
Owner reports constant burning smell from under hood, hot engine compartment, and concern about potential engine fire. Coolant level drops intermittently causing sputtering.
When: Intermittent over one-year period; severity increased over time
Symptoms owners cite: Constant burning smell from under hood (some days stronger than others); Engine compartment very hot when opened; Coolant level drops/leaks randomly; Engine sputtering or vibration at traffic lights; Warning lights come on intermittently but not consistently; Intermittent fault codes
Repairs/costs cited: Engine replacement required; cost quoted at $6,500 by local mechanic. Owner suspects vehicle was abandoned by previous owner before engine replacement became their liability.
Recalls/TSBs owners mention: Dealership offered no remedy or assistance despite contact.
Exhaust odor and fume intrusion into cabin
Owner reports strong intermittent sulfur and exhaust odor in cabin present while running, idling, coasting, and at rest. Fumes became so strong windows cannot be opened. Family experienced headaches and severe nausea.
When: Intermittent since purchase in July; intensified over time
Symptoms owners cite: Intermittent sulfur and exhaust odor in cabin; Odor present during all driving conditions (idling, freeway, acceleration); Strong enough to prevent driving with windows down; Family headaches and severe nausea; Passenger nearly passed out on hour-long drive
Repairs/costs cited: Cabin air filter replaced at first service visit; did not resolve issue. Vehicle at dealership for second visit; case opened with Ford Motor Company HQ.
Recalls/TSBs owners mention: Dealership initially replaced cabin air filter. After sulfur odor mentioned, dealership indicated need to contact Ford Motor Company HQ and open case.
Oil leak from engine seals/reservoir
Oil leaks from engine seals in reservoir area. One mechanic warned potential could lead to vehicle fire.
When: Oil leaking before report; timing not specified
Symptoms owners cite: Oil leaking onto garage pavement; Oil leak from seals in reservoir area
Repairs/costs cited: Dealership initially blamed independent mechanic for improper oil change service. Upon investigation, dealership found oil leaked from seals in reservoir and repaired.
Recalls/TSBs owners mention: Dealership ultimately repaired issue.
