Just hours after routine oil and filter change, I pulled out onto the highway, accelerating to access the roadway at a reasonable speed of traffic. The engine began to slow, and then stopped completely.....no power, nothing!!!! I was almost rear-ended and catapulted into oncoming traffic. The dealership was contacted and brought the car in, where the service manager said the engine shut down…

What stands out
Owners have filed 36 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.
Among the 14 model years of Ford Taurus in our records for engine problems, this one ranks #3 by owner-complaint volume.
The failure pattern owners describe
Buyer takeaway: The 2011 Taurus, especially the SHO with EcoBoost, has widespread and serious engine problems. The integrated water pump design is prone to failure, dumping coolant into the oil and requiring engine replacement ($3,000–$10,000+), plus multiple owners report sudden stalling with no warning that kills power steering and brakes—a genuine safety hazard. Pass on this model unless the engine and cooling system have been recently certified by an independent mechanic.
The 2011 Taurus engine cluster shows two dominant failure patterns, both severe. First, the internal water pump (mounted inside the engine block and driven by the timing chain) fails and floods the crankcase with coolant. This destroys bearings, cracks blocks, and snaps connecting rods. Owners find milky oil, smell coolant, overheat suddenly, and lose power—sometimes on the highway. A complete engine replacement is the only fix, costing $3,000 to $10,000, and it takes dealers months to source a replacement engine. Owners emphasize this is a design defect peculiar to the 3.5L V6 DOHC; competitors use external pumps.
Second, the engine stalls without warning at any speed—idling at lights, cruising at 65 MPH, backing up. The driver loses all power, steering, and brakes simultaneously. One owner nearly got rear-ended; another was stranded on a dark interstate in winter. Some stalls relate to cylinder misfires (codes P0300, P0302, P0306), but dealers often cannot diagnose the root cause even after replacing ignition coils or—in one extreme case—the engine three times. A few complaints mention hesitation, rough idle, or unresponsive throttle. One owner accidentally activated the push-button start while driving at highway speed. A single report mentions turbocharger oil leak and fire.
Owners uniformly report no warning before failure and dealer diagnostics that frequently fail to replicate or resolve the issue.

Failure modes owners describe
Internal Water Pump Failure with Coolant Intrusion
The 3.5L V6 DOHC engine uses an internal water pump driven by the overhead cam chain. When it fails, coolant floods into the engine crankcase, mixing with oil and causing bearing destruction, potential hydro-lock, and catastrophic engine damage. Owners report this as a design flaw specific to Ford's integrated water pump placement.
When: 80,900 miles to 156,000 miles; some failures occur early (52,300 miles); no consistent mileage threshold
Symptoms owners cite: Temperature gauge spikes rapidly to hot; Loss of engine power while driving; Engine stalls without warning; Overheating; Coolant smell; White or sweet odor from engine; Smoke or steam from engine compartment; Loss of power steering and brakes upon stall; Check engine light illumination; Oil appears milky or thin with coolant contamination; Knocking or abnormal engine noise before failure
Codes mentioned: P0300, P0302, P0306
Repairs/costs cited: Complete engine replacement required. Owners cite repair costs of $3,000 to $10,000+ for engine replacement. Some dealers quote $8,000–$9,000. Entire engine must be removed to access the internal water pump. Timing chain fracture and connecting rod bearing damage documented in several cases.
Recalls/TSBs owners mention: TSB #7T4Z*9E926*FA mentioned in one complaint; some owners report Ford referred them to NHTSA Hotline instead of providing assistance. No recall identified in narratives.
Cylinder Misfire and Power Loss During Acceleration
Owners report sputtering, shuddering, and loss of power during acceleration, particularly on uphill grades or from stops. Misfire codes (P0300, P0302, P0306) are documented. One owner had the engine replaced three times for the same symptom; another had ignition coils and spark plugs replaced without resolving the issue.
When: Early in ownership (as low as 3,300 miles) to 105,213 miles; occurs sporadically and without pattern
Symptoms owners cite: Engine sputters and loses power during acceleration; Shuddering or hesitation from stop or low speeds; Rough idle and engine shake at low speeds; Check engine light, often blinking; Engine enters limp mode; Misfire and catch sensation when pressing accelerator; Cruise control cancels unexpectedly at highway speed; Vehicle nearly stalls at stop signs; Difficulty replicating problem at dealership
Codes mentioned: P0300, P0302, P0306
Repairs/costs cited: Ignition coils and spark plugs replaced in one case without resolving issue. Engine replaced up to three times in one complaint with repeated failure. Dealers unable to duplicate or diagnose root cause in multiple instances.
Recalls/TSBs owners mention: Dealer cited 'throttle body and motor assembly deficiency' in one case; TSB #7T4Z*9E926*FA referenced. Manufacturer offered no known improvement strategy in other complaints.
Unexpected Engine Stall with Loss of Power Steering and Brakes
Vehicle suddenly and without warning loses all engine power while driving at various speeds (30–70 MPH), forcing the driver to coast to a stop and losing power-assisted steering and braking. Multiple owners report this happened at traffic lights, stop signs, railroad crossings, or while coasting downhill. Safety risk is severe.
When: Mileage varies from 700 miles to 106,000 miles; one incident occurred during routine driving after oil change
Symptoms owners cite: Complete loss of engine power without warning; Engine stalls mid-traffic or mid-highway; No motive power to restart; Loss of power steering; Loss of power brakes; Check engine light and dashboard lights illuminate; Vehicle cannot be steered or braked safely; Occurs randomly with no discernible pattern; Occurs after railroad crossing (rattling event) in one case
Codes mentioned:
Repairs/costs cited: One case attributed to insect lodged in mass air flow (MAF) sensor filament; service manager stated this was only the second time seen. Oil drain inspection revealed coolant mixed in oil in another case, pointing to water pump failure as root cause.
Unintended Engine Shutdown and Throttle Control Issues
Engine unexpectedly shuts down or fails to respond to throttle input. In one case, the start/stop button is positioned adjacent to the radio power button, making accidental shutdowns during driving possible (and documented). In other cases, the vehicle continues to accelerate despite driver releasing the throttle, or hesitates and fails to respond.
When: Varies from 2,000 miles to full service life; button-related incident occurred during highway driving at 70 MPH
Symptoms owners cite: Engine cuts off unintentionally while driving; Vehicle accelerates uncontrollably despite driver not depressing throttle; Sudden loss of response to accelerator pedal; Engine hesitation at various speeds; No warning before shutdown or loss of control; Push-button start activates and cuts engine if struck accidentally; Seat belt tightens suddenly upon abrupt deceleration
Codes mentioned:
Repairs/costs cited: Push-button design flaw identified; one owner suggested a protective cover over the start button. No repairs documented for other throttle/control issues.
Recalls/TSBs owners mention: Owner reported writing to Ford multiple times regarding button design without receiving response; directed to local dealer.
Turbocharger Oil Leak and Fire
One complaint reports an oil leak to the turbocharger while driving, resulting in vehicle fire.
When: Mileage not provided
Symptoms owners cite: Oil leak from turbocharger; Vehicle fire while driving
Codes mentioned:
Repairs/costs cited: Vehicle burned to the ground; no repair details provided.

I purchased the car used with 28,000 mile and I have't had a single issue with it until today current mileage 52,300 the car for no reason just cut off and the oil light was on , I was able to pull over and restart the car . The scary part is there is no type of warning just goes dead .
Had my Ford for less than 6 months, and has 80,000 miles on it. Looks brand new, in excellent shape and yet on the way home from the grocery store, it began overheating. The tempature gage shot up and the engine started cutting out. We pulled over and the vehicle was smoking. We started adding water and coasting down the mountain until we could get home. Called several mechanics and find out that…
