2012 Ford Expedition Problems

What owners report

Owners of the 2012 Expedition most often describe an unexpected transmission downshift, frequently at highway speed, sometimes accompanied by the speedometer dropping to zero and several warning lights. These reports span a wide mileage range and are the dominant theme across the sampled complaints; tailgate paint bubbling and occasional electrical and engine concerns come up less often.

   Unexpected transmission downshift into first gear

   • 52 complaints (44%)
   • median 114,477 mi at 6.8 yrs old (39 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2016–2026

   Complaints describe the transmission dropping into first gear without warning, sometimes at 55-70 mph, causing the vehicle to slow abruptly and in some cases the rear wheels to lock or the vehicle to enter limp mode. Several owners say the speedometer dropped to zero and warning lights (wrench, check engine, fuel level, tire pressure) appeared, and that restarting the engine restored normal operation. Some report the downshift returned after a dealer reprogrammed the control module, and several say they were told their VIN was not covered by a recall describing the same symptom; others say a dealer diagnosed an output shaft speed sensor or the transmission leadframe. Reported from low mileage up to well past 200,000 miles, most often during highway driving at 45-70 mph.

   What to check: Test drive at highway speed and ask whether the PCM reprogramming for the downshift condition was performed; have a shop check for stored codes related to the output shaft speed sensor and the transmission leadframe.

   “I was driving about 40 MPH, and the vehicle on the vehicle appeared to have a sudden downshift. The card drastically reduce speed very quickly and remained in a low gear although it said it was in drive. The description of what happened matches recall 16s19, however, they said my specific vehicle was not available for that recall. Same year and very similar issue.”

   NHTSA complaint #10894684, filed 2016-08, 69,000 miles

   “Our 2012 Expedition is experiencing repeated intermittent loss of transmission output and unexpected downshift into first gear (as noted in the Ford recall notice dated april 2016). This is a major safety risk for our family. We bought the vehicle as a certified Ford, but the recall hadn't been addressed. To deal with the problem, we brought the vehicle to another Ford dealer. …”

   Electrical system

   Speedometer drops to zero with warning lights

   • 26 complaints (22%)
   • median 95,000 mi at 6.5 yrs old (22 state mileage)
   • filed 2013–2025

   Owners describe the speedometer and fuel gauge dropping or reading erratically while driving, often together with a wrench or check engine light and intermittent loss of power. Many say the gauges reset after shutting off and restarting the vehicle, and some were told the cause was the transmission output shaft speed sensor or a wiring harness issue. The symptom often appears alongside the transmission downshift reports. Reported from about 30,000 miles upward, typically while cruising at highway speeds.

   What to check: During a test drive, watch whether the speedometer and fuel gauge hold steady; ask if any speed sensor or cluster-related service has been done and whether codes were retrieved.

   Body and structure

   Paint bubbling and corrosion on aluminum tailgate

   • 10 complaints (8%)
   • median 53,000 mi at 4.2 yrs old (7 state mileage, few)
   • filed 2015–2023

   Complaints describe blistered and peeling paint on the rear liftgate, with owners saying the dealer identified it as corrosion of the aluminum panel under the paint. Several report being told the condition is cosmetic or not covered by the corrosion warranty unless the metal is perforated, and that it tends to spread until the panel is repainted or replaced. Some also mention corrosion on the rear of the vehicle or the possibility of the hood being affected. Usually noticed between roughly 46,000 and 76,000 miles, often on vehicles only a few years old.

   What to check: Inspect the tailgate, hood edges and panel seams for bubbles or peeling paint and ask whether any panel has been repainted or replaced.

   “I just bought this vehicle used. The paint on the tailgate of my truck has bubbled up in several locations and started to peel. After talking to the local dealership and the manufacturer, they stated that it's a cosmetic problem, not covered by the corrosion warranty. After much research, I have realized that this is a very common problem. I owned a similar make and model that was 9 years older and thought it was a limited issue. Unfortunately, the manufacturer knows they have an issue, but refuse to cover it. …”

   NHTSA complaint #10968225, filed 2017-03, 75,000 miles

   “Paint blisters are starting to appear on rear lift gate where the handle is attached. Dealer has indicated that this is corrosion due to the aluminium material that the lift gate is made of and poor prep work or contamination from the factory paint.”

   Engine stalling or loss of power (cam phaser, low oil

   Mentioned in 4 of 60 sampled complaints

   A few owners describe the engine losing power or stalling, with one report of cam phaser damage leading to manifold and piston damage and an engine replacement, and another of low oil pressure affecting the engine. Another complaint describes the vehicle shutting off while driving and restarting only intermittently, with the dealer saying the VIN was not covered by a recall. A service bulletin for the modular engines describes upper-end noise, rough running and misfire traced to camshaft and roller follower wear. Reported between roughly 89,000 and 154,000 miles.

   1 related service bulletin

   What to check: Listen for upper-engine ticking or rattle on a cold start and ask whether the camshaft and roller followers have been inspected; check oil level and service records.

   “Car was driving fine and then it stopped accelerating, wouldn't change gears or go over 20mph. We brought it to our local repair shop who thought it was the timing chain. We then had it towed to the Ford dealer (koons in falls church, va) they said that it is a problem with low oil pressure and the engine has been affected. They gave us an estimate of $11,000 to repair (needs a new engine). The car only has 89,000 miles and has been perfectly maintained. …”

   NHTSA complaint #11153081, filed 2018-11, 89,000 miles

   “Cam phaser issue resulting in heated/cracked manifold, melting into piston 4, disabling engine. Requires full engine replacement at $6k parts & labor.”

   NHTSA complaint #11124279, filed 2018-09, 154,000 miles

Buying note. The transmission downshift reports are the main thing to weigh on this model year, so confirm whether the reprogramming and any leadframe service were completed and check for stored transmission codes before purchase. Inspect the tailgate and hood paint for bubbling, and check the rear air suspension and front wheel bearings on a test drive.
