What stands out
Among the 5 model years of Mercury Milan in our records for powertrain problems, this one ranks #3 by owner-complaint volume.
No new NHTSA powertrain complaint has been filed on this vehicle in over 14 years — the issue may be aging out of the active population.
The failure pattern owners describe
The powertrain problems in these 20 complaints center on three main culprits: the transmission, throttle control, and PCM.
Transmission failures start early—some owners report slipping or jerking within weeks of purchase. The 5-speed automatic jerks into reverse, won't engage beyond third gear, or slips under acceleration. One owner had the entire transmission replaced, then had the same problem return before reaching the freeway. Another spent $1,650 on a rebuilt unit only to have it fail within a week. Dealers and independent shops rebuild the transmission multiple times on the same vehicle without solving it. Transmission fluid darkening suggests internal wear, and dealer networks have documented other Milans with identical transmission failures.
Throttle-body shutdowns cause sudden loss of power at highway speeds (65–75 mph) with no warning. The wrench light comes on; the engine keeps running but won't accelerate. Some owners report this happens once, then intermittently over months. Others experience it multiple times daily. Resetting the system by turning the car off and restarting temporarily restores power. Ford issued a customer satisfaction program for this defect, but only for later model years—2007 owners are not covered. The throttle bodies are expensive to replace.
PCM failures accompany ignition coil problems, causing sputtering, stalling, and check engine lights. At least one owner needed a second PCM replacement. Ford placed PCMs on sales hold due to widespread demand across multiple model lines, indicating a known systemic issue.
All three failure modes can strand owners mid-drive, creating genuine highway safety exposure.

Failure modes owners describe
5-Speed Automatic Transmission Jerking & Loss of Drive
Transmission jerks when shifting into reverse, fails to engage beyond 3rd gear, or slips entirely—sometimes intermittently, sometimes persistently. Owners report gears slipping under load, hard shifting, and sudden loss of power during acceleration. Multiple complete transmission rebuilds or replacements fail to resolve the issue on the same vehicle.
When: Occurs under normal driving conditions and at various mileages (19,800 to 111,656 miles); some failures emerge early in ownership.
Symptoms owners cite: Jerking when shifting into reverse; Won't engage beyond 3rd gear; Gears slipping under acceleration; Hard shifting at 2500 RPM; Engine revving with no vehicle movement (high RPM, no acceleration); Transmission drops out of overdrive; Difficulty shifting and changing gears
Codes mentioned: Powertrain warning light illumination, Malfunction Indicator Lamp (MIL)
Repairs/costs cited: Full transmission replacement; solenoid and controller replacement; transmission fluid nearly black (indicating internal wear); multiple rebuild attempts; owners cite $1,650 for rebuilt transmission; repairs repeatedly fail to restore normal operation.
Recalls/TSBs owners mention: Ford factory service rep recommended vehicle replacement; extended warranty refused by dealer citing lack of required 70,000-mile service; customer satisfaction program mentioned but not applicable to 2007 model year for some owners.
Throttle Body / Electronic Throttle Control Failure
Sudden loss of engine power and deceleration while driving at highway speeds, with yellow wrench light illuminating. Vehicle loses ability to accelerate, sometimes won't restart immediately. Some incidents occur intermittently; others become persistent with surging and jerking. Owners report high cost of throttle body replacement.
When: Can occur at any speed or driving condition; some failures happen intermittently over months, others suddenly during highway driving (65–75 mph); mileage varies (85,000–111,656+ miles).
Symptoms owners cite: Sudden loss of power while driving; Engine continues running but no response to accelerator; Yellow wrench light illumination; Vehicle decelerates to 5–10 mph or won't exceed 55 mph; Wrench light on all the time (persistent); Hard jarring of transmission when throttle shuts down; Vehicle surging while driving; Throttle actuator shutdown
Codes mentioned: Yellow wrench light (powertrain limp-in mode), Check Engine light
Repairs/costs cited: Throttle body replacement (owners note these are very expensive); system reset attempted but fails to permanently resolve; one owner reports PCM replacement alongside throttle body work.
Recalls/TSBs owners mention: Ford Customer Satisfaction Program 13N03 referenced by one owner regarding electronic throttle body connectivity; recall issued for later model years (2011) but not 2007; Ford dealer cited liability concerns and refused to discuss coverage.
PCM (Powertrain Control Module) Failure & Coil Misfire
PCM failures occur in conjunction with ignition coil failures, causing sputtering, stalling, and loss of power. Vehicles exhibit check engine light flashing, poor running condition, and inability to restart. One owner reports PCM short-circuiting. Multiple PCM replacements documented, with Ford placing PCM on sales hold due to widespread demand.
When: Failures documented across various mileages (some early in ownership); at least one replacement required a second time; PCM shortage suggests ongoing issue affecting multiple model years.
Symptoms owners cite: Sputtering and shimmying at startup; Check Engine light flashing then staying on; Vehicle stalls while driving or at stops; Vehicle runs terribly after starting; Repeated cutting off; Loss of acceleration
Codes mentioned: Check Engine light, Diagnostic indicates coil and PCM fault
Repairs/costs cited: Spark plugs, throttle body, and PCM replaced; one owner reports ignition coils, fuel injector, and PCM replacement; PCM on sales hold by Ford—delayed availability noted as of June 2012; repair cost escalating with repeated PCM replacements.
Recalls/TSBs owners mention: Ford aware of PCM problem affecting Fusion, Taurus, Edge, Lincoln Zephyr, MK, MKX, Mercury Milan, and Sable; PCM placed on sales hold.
Transmission Hard Shifting & Jerking with Check Engine Light
Transmission shifts hard at 2500 RPM, jerks in reverse, or exhibits erratic shifting behavior. Check Engine or powertrain warning lights illuminate. Issue may be misdiagnosed as motor mount problem. Owners report transmission fluid darkening and repeated failures after repair attempts.
When: Develops progressively over time; recurs shortly after repair attempts (within days to weeks); present at 50,000+ miles and higher.
Symptoms owners cite: Hard shifting at 2500 RPM; Jerking in reverse; Transmission slipping; Powertrain warning light on; Transmission fluid darkening
Codes mentioned: Powertrain warning light
Repairs/costs cited: Transmission completely rebuilt multiple times without lasting resolution; shop eventually replaced transmission three times within six months; one owner reports motor mount check performed (negative finding) at dealer.
Recalls/TSBs owners mention: Dealer initially misdiagnosed as motor mount; extended warranty refused due to lack of required servicing; no manufacturer response documented.
Drive Line Bearing Failure
Bearing on the drive line fails early in vehicle life. Owner reports part unavailable from Ford dealership for over a month, preventing repair.
When: At 29,000 miles (very early)
Symptoms owners cite: Bad drive line bearing
Repairs/costs cited: Replacement part unavailable from Ford for over one month.
