Could hear a loud metal to metal grinding sound. Finally had the expedition towed to dealership. 3 struts need to be replaced as well as the shocks. Driver side bearing was worn out. The passenger side is almost there. The expedition only has 50,000 miles. After getting this information from the dealer we read the power train warranty. The warranty will only replace the driver side bearing. When…

What stands out
Powertrain accounts for 55% of every owner complaint on file for this vehicle — the dominant problem area across 6 categories tracked.
Owners have filed 64 powertrain 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.
The failure pattern owners describe
Buyer takeaway: A substantial cluster of 2012 Ford Expeditions report sudden transmission downshifts into 1st gear at highway speeds, causing loss of vehicle control and near-collisions; owners say Ford's recalls exclude many vehicles with identical symptoms and that repair attempts often fail. Safety risk is real and well-documented across many unrelated consumer reports.
The dominant complaint across these 50 narratives is unintended transmission downshifts, usually into 1st gear, while driving at 40–75 mph. Owners describe rapid deceleration, rear tire lockup, speedometer dropping to zero, and engine RPM spikes—sometimes all at once. Several report near-collisions when vehicles behind them had to brake or swerve. One owner's vehicle locked up tires on a highway, nearly putting family in oncoming traffic.
Many also report the instrument cluster going dark or flickering at the same moment the transmission drops, with false fuel and tire warnings illuminating. Restarting the vehicle temporarily clears symptoms, but the downshift recurs unpredictably—some owners say it's happening more frequently.
The core technical issue cited is a transmission molded lead frame failure affecting the output speed sensor. Owners consistently point to NHTSA recall campaigns 16V248000 and 16S19, plus older campaign 12V190000, but many report their VINs are excluded from recall coverage despite having the same year, model, transmission, and manufacturing plant as recalled units. Dealers have attempted power control module reprogramming and lead frame replacement, but repairs sometimes fail within days; one owner had a recall repair completed, then experienced the downshift again the next day.
Owners also report transmission fluid service and software updates providing no permanent relief. Some vehicles are beyond the 10-year/150,000-mile warranty window, leaving owners to pay $750–$1,000 out of pocket. Dealers cite parts shortages, preventing completion of authorized repairs.

Failure modes owners describe
Unintended downshift to 1st gear at cruising speed
Transmission downshifts abruptly into 1st gear while vehicle is traveling at highway or city speeds (typically 40–75 mph), causing rapid deceleration, rear tire lockup, and loss of vehicle control. Engine RPMs spike. Speedometer often drops to 0 mph simultaneously. Occurs without warning and may cause following vehicles to brake hard or swerve. Vehicle may enter limp mode.
When: Primarily 40–75 mph cruising on highways and main roads; intermittent but becoming more frequent over time in some cases
Symptoms owners cite: Abrupt downshift into 1st gear; Rapid deceleration; Rear tires lock or squeal; Speedometer drops to 0 mph; Engine RPMs elevate; Wrench symbol on dashboard; Check engine light (intermittent); Vehicle enters limp mode; Instrument cluster resets or goes blank; Low fuel indicator may illuminate falsely
Codes mentioned: P0270 (Output Speed Sensor), P0742 (Torque Converter Clutch Circuit Stuck On)
Repairs/costs cited: Transmission molded lead frame replacement; power control module reprogramming; transmission output speed sensor replacement. Some owners report repair shops unable to source parts. Some repairs fail; problem recurs within days or weeks.
Recalls/TSBs owners mention: NHTSA Campaign 16V248000 (Power Train); NHTSA Campaign 16S19; Customer Satisfaction Program 19N01-Supplement #1 (Power Train). Many owners report their VINs excluded from recall despite same year, model, transmission, and manufacturing plant. Warranty coverage limited to 10 years/150,000 miles; owners beyond mileage refused coverage. Parts shortages reported by dealers.
Transmission loss of motive power / slipping into neutral
Transmission loses drive torque while vehicle is in motion, acting as though vehicle is in neutral. Vehicle decelerates unexpectedly without driver input. May occur during acceleration or at cruise. Recovery typically requires restart or shifting to lower gear.
When: At various speeds, including during acceleration from stop and highway cruising; intermittent
Symptoms owners cite: Loss of motive power mid-drive; Transmission acts as if in neutral; Unexpected deceleration; Check engine light (sometimes); May require restart to restore drive
Codes mentioned: Front end harness issue (unconfirmed by scan tools)
Repairs/costs cited: Transmission fluid service (flush/filter/fill) attempted with temporary relief; some cases diagnosed as front end harness issue but not repaired due to parts availability. No permanent fix confirmed.
Recalls/TSBs owners mention: Most cases not covered under recall. Dealers unable to duplicate intermittent failures. No parts availability noted for harness repair.
Transmission jerking, jumping, or harsh acceleration from 1st to 2nd gear
Vehicle jerks violently or 'jumps' when accelerating from 1st to 2nd gear, feeling as though struck from behind. Occurs on repeated acceleration cycles. Software updates applied at dealership have not resolved issue; some owners report worsening after each dealership visit.
When: During initial acceleration from stop, approximately May–June 2013 onward in one early report; intermittent but recurring
Symptoms owners cite: Violent jerk or jump during 1st–2nd gear transition; Feels like vehicle has been hit from behind; Jerking severe enough to trigger false brake perception (driver thought rear-ended); Check engine light (sometimes); Problem worsens after dealership software updates
Repairs/costs cited: Dealership software updates attempted three times; problem worsened each time. No permanent fix achieved.
Recalls/TSBs owners mention: Software reprogramming attempted multiple times without success.
Vehicle rollaway after engine shutdown
Vehicle rolls down driveway after engine is turned off and driver exits, crossing street and colliding with neighboring property. Suggests transmission or parking brake failure preventing vehicle from staying stationary on incline.
When: Upon engine shutdown while parked on incline (driveway)
Symptoms owners cite: Vehicle rolls unexpectedly after shutdown; Crosses roadway and strikes obstacle
Repairs/costs cited: Not diagnosed; consumer noted faulty gear shifter and parts on backorder.
Recalls/TSBs owners mention: No manufacturer response documented.
Transmission getting stuck in single gear (3rd or other non-1st gear)
Transmission downshifts and becomes locked in a single mid-range gear (e.g., 3rd gear), refusing to shift despite accelerator input. Vehicle unable to accelerate to normal highway speeds. Requires restart or shift to neutral to reset.
When: During highway driving or leaving work; intermittent
Symptoms owners cite: Transmission locked in single mid-range gear; Unable to accelerate despite pedal depression; Vehicle stuck in 3rd gear (one example) despite Drive selection; May require restart to clear
Repairs/costs cited: One case diagnosed as front end harness issue with transmission; not repaired due to parts unavailability.
Recalls/TSBs owners mention: Dealer unable to duplicate in shop environment.
Speedometer and instrument cluster malfunction concurrent with downshift events
Speedometer drops to 0 mph, fuel gauge and odometer go blank, dashboard lights flicker, and wrench symbol illuminates simultaneously with transmission downshift. All symptoms reset when vehicle is restarted, though failure may recur.
When: Concurrent with downshift events, typically at 40–75 mph
Symptoms owners cite: Speedometer reads 0 mph while vehicle in motion; Fuel gauge inoperative; Odometer blank; Dashboard lights flicker or dim; Wrench warning symbol illuminates; Low fuel indicator illuminates (false alarm); Tire sensor warning may illuminate; All symptoms resolve on restart
Repairs/costs cited: One case: transmission lead frame replacement completed; problem recurred at higher mileage (167,759 miles, beyond 150,000-mile warranty limit).
Recalls/TSBs owners mention: Warranty coverage limited to 10 years/150,000 miles; beyond that mileage, owners responsible for cost.

My transmission shifts down in situations it shouldn't. It also doesn't matter how fast I am going. This creates an issue with steering. I tried to have it fixed but they couldn't figure out what was wrong and it doesn't do it all the time so I couldn't recreate the problem for them. The problem always happens when I am traveling at high speeds (60-80) and usually when I have been going up and…

While driving with my four children the vehicle will down shift all of a sudden while traveling down the freeway. Brought it to the dealership and was told it was not under warranty they said to call the Ford 1-800 #. Called 1-800 # and was told that it was not on the recall yet. So I am expected to pay for a repair which could be placed on a recall list. The diagnosis was the lead frame and…
On many occasions from around may or june of 2013, when the car is accelerating from first to second gear it "jumps". It feels as if someone has hit the back of the vehicle. The vehicle was taken back to the dealership 3 times. Each time they have updated the software and supposedly solved the problem. After each return of the vehicle the problem had only gotten worse. The second time after…
