Ford Expedition 2018–2024

4th generation · U553 (Ford T3 frame, aluminum body) · 2,266 complaints, 632 with mileage

Owners filed 2,266 complaints with NHTSA about the 2018–2024 Ford Expedition, and 632 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.

Failures are spread across the mileage range, with the middle half between 27,000 and 89,000 miles. The median is 60,000 miles.

The most-reported areas are the transmission and driveline (32.6% of complaints, typically around 69,200 miles), the engine (14.5% of complaints, typically around 70,015 miles), problems owners could not categorise (8.6% of complaints, typically around 8,750 miles).

42 recall campaigns cover this generation.

Which systems, and when

Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 60,000 miles; the figures below show which parts of the car run ahead of that and which run behind.

The transmission and driveline accounts for 32.6% of complaints (738 reports, 160 of them with a mileage figure), with a median of 69,200 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 40,000 and 96,000 miles.

A single system taking 32.6% of all complaints is a concentration worth noting. It means that for this generation, most of what owners reported came back to one area of the car rather than being distributed across many small faults.

The engine accounts for 14.5% of complaints (328 reports, 103 of them with a mileage figure), with a median of 70,015 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 50,000 and 93,000 miles.

Problems owners could not categorise accounts for 8.6% of complaints (196 reports, 18 of them with a mileage figure), and it fails early — a median of 8,750 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 3,000 and 29,000 miles.

The electrical system accounts for 7.0% of complaints (158 reports, 45 of them with a mileage figure), and it fails early — a median of 25,000 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 11,000 and 50,000 miles.

The seat belts account for 6.0% of complaints (135 reports, 58 of them with a mileage figure), with a median of 73,532 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 60,000 and 95,801 miles.

Throttle and speed control accounts for 3.2% of complaints (72 reports, 14 of them with a mileage figure), with a median of 46,500 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 15,263 and 79,000 miles.

Differences between model years

Within this generation, complaint volume is not constant across model years. The 2019 model year drew the most — 612 complaints — while 2023 drew the fewest at 93. The median year sits at 295.

That makes 2019 an outlier: roughly 2.1 times the median year of this generation. A single year standing that far apart usually reflects either a first-year issue that was later corrected, or a component change introduced for that year. Anyone shopping this generation has a straightforward reason to prefer a different year, all else being equal.

Recalls and what they cover

NHTSA records 42 recall campaigns covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.

The campaigns cluster around the electrical system (5), the seat belts (5), the transmission and driveline (5). Repeated recalls against the same area of the car generally mean the first remedy did not fully resolve the underlying problem.

Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.

Reported severity

Of the 2,266 complaints filed against this generation, 61 reported a crash; 38 reported a fire; 165 reported an injury. Crash-involved reports represent 2.7% of the total.

These are owner-reported outcomes, not verified investigations, and they are not adjusted for how many of these vehicles are on the road. They are included because the distinction between a fault that strands a car and a fault that causes a collision is the one that matters most, and it is not visible in a complaint count alone.

What this means if you are buying one

For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 27,000 and 89,000 miles, with a median of 60,000. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.

On inspection, the transmission and driveline and the engine are where this generation's reports concentrate, so those are the areas worth a specific look. The transmission and driveline in particular shows a median failure mileage of 69,200, which gives a concrete number to compare against the odometer of any car you are considering.

None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.

Documented problems

Transmission 2018-2020

10R80 10-speed automatic harsh and erratic shifting, clunk on the 4-5 and 6-7 changes, and torque converter lockup shudder. Addressed through repeated PCM/TCM recalibrations rather than hardware.

Engine / fire risk 2021-2023

Under-hood fires traced to the engine compartment on 3.5L EcoBoost Expedition and Navigator, prompting a Ford recall with an interim advice to park outdoors and a revised under-hood harness/battery routing remedy.

Electrical

Battery drain and stop/start system faults on early build years.
