Owners report catastrophic engine failures without warning—violent shaking, sudden loss of power, engine seizing—typically resulting in complete engine replacement. These failures occur across mileage ranges from under 25k to 100k miles. One failure at 80k miles caused a collision when the engine died in an intersection, totaling the vehicle and injuring multiple occupants. Another failure at 25k miles yielded a thrown rod; a third involved camshaft and timing chain failure that recurred after dealer repair.
Separate from full catastrophic failure, owners describe sudden loss of motive power while driving—coasting to a stop with no restart or delayed restart. One owner experienced this four times over 30 days; the dealer blamed low fuel despite gas in the tank and fuel pump module replacement.
Morning stalling plagues some vehicles: engine cranks but shuts down repeatedly within the first 1-2 minutes of startup, typically resolving later in the day. One vehicle still experienced stalling after a vapor valve replacement and three weeks at a dealership.
Additional engine-related failures include cooling system water intrusion into the turbo (requiring engine replacement), body control module water intrusion (false warning displays), catalytic converter faults, and transmission engagement delays with jerking. One owner reported active recalls with no available remedies. Exhaust fumes in the cabin occur multiple times weekly on at least one vehicle.
Failure modes owners describe
Catastrophic engine failure / rod knock
Engine seizes without warning and loses all power. Disassembly reveals thrown rod. Entire engine replacement required.
When: ~25k miles (#1); 38k miles (#9); under 100k miles (#11)
Symptoms owners cite: Violent shaking while driving; Complete loss of power; Vehicle will not restart; No warning lights before failure; Abnormal engine knocking sound (#9); Engine shudders (#11)
Repairs/costs cited: Engine replacement; #9 had camshaft and timing chain failure diagnosed, repaired but reoccurred
Recalls/TSBs owners mention: Recall 24V-598 issued for 3.3L engine failures (police interceptor Explorers); owner suspects 3.0L engines also affected but Ford denies
Complete loss of motive power while driving
Vehicle loses all power mid-intersection or during normal driving with no prior indication. May or may not restart after delay.
When: 80k miles (#2); multiple incidents over 30 days (#6); 61.5k miles (#4)
Symptoms owners cite: Sudden loss of power while driving; Vehicle coasts to stop; No acceleration; Will not restart (or restarts after delay); No warning lights illuminated before loss of power
Repairs/costs cited: #6 had fuel pump module replaced but failure recurred; #2 resulted in collision and vehicle total loss
Stalling and repeated shutdown on startup
Engine cranks but stalls repeatedly during morning startup, typically within first 1-2 minutes. May restart easily or after delay. Occurs predominantly in mornings.
When: 4 days after purchase; fuel pump issue recurred after 10 minutes running in driveway (#6)
Symptoms owners cite: Repeated stalling after engine crank (1-4 times within 1-2 minutes); Stalling when putting vehicle in gear; Stalling during acceleration attempts; Primarily occurs in mornings; Eventually resolves during the day
Repairs/costs cited: #5 vapor valve replaced but stalling continued; vehicle at dealer 3+ weeks without resolution
Engine overheating with cooling system failure
Engine runs hot with cylinder head temperature alarm. Water leaks into turbocharger, engine and cooling system fail. Sensor fails to warn driver of elevated temps.
When: 105k miles (#3); occurred 2-3 years prior to current ownership
Symptoms owners cite: Cylinder head temperature overheated message displayed; Water leaking into turbocharger; Engine running hot
Repairs/costs cited: Engine replacement or turbocharger replacement as temporary repair recommended
Recalls/TSBs owners mention: Manufacturer opened case and referred contact to NHTSA
Catalytic converter failure
Catalytic converter becomes faulty, requiring replacement. Associated with check engine light and abnormal gasoline odor.
When: 72,378 miles (#7)
Symptoms owners cite: Check engine light illumination; Abnormal gasoline/exhaust odor in cabin; No rattling sound noted; narrative states 'rattling sound from front end' but this may be secondary
Repairs/costs cited: Catalytic converter replacement needed
Recalls/TSBs owners mention: Manufacturer notified
Engine control system water intrusion
Water intrusion into body control module fuse panel causes check engine light and false warning displays (fuel door, etc.) when vehicle is off. Vehicle previously required transmission software update.
When: 61.5k miles (#4)
Symptoms owners cite: Check engine warning via app when vehicle off; Fuel door open message displayed; Intermittent speedometer failure; Previous transmission hesitation and software update required
Repairs/costs cited: Battery and body control module fuse panel replacement required; vehicle not repaired
Recalls/TSBs owners mention: Manufacturer case filed
Transmission engagement delay and jerking
Delay in transmission engagement when shifting between park and drive/reverse. Jerking motion occurs during gear engagement and automatic upshifts.
Symptoms owners cite: Delay when shifting from park to drive or reverse; Jerking motion during engagement; Delay during automatic upshifts (rpm increase); Delay when shifting from moving gear into park
Exhaust fumes in cabin
Strong exhaust or gasoline fumes in cabin during normal driving, occurring multiple times per week.
Symptoms owners cite: Intense exhaust/gasoline smell in cabin; Occurs several times per week
