Some used-car guides call the 2015-2017 Ford Expedition recall-free. NHTSA's database says otherwise. The front blower motor behind the glove box has caused 25 reported vehicle fires. The brake master cylinder can leak fluid into the booster. Two separate campaigns cover a rearview camera that goes blank or shows an inverted image. That's the EcoBoost half of this generation.
The other half, 2007 through 2014, runs a 5.4-liter V8 with a two-piece spark plug design that can shear off in the cylinder head at the first major service interval, sometimes taking threads with it.
Same three-row SUV. Same nameplate. Two completely different trucks to shop for, and the dividing line is a single model year: 2015.
This Generation at a Glance
The 3rd generation Expedition rides on Ford's T1 platform, the same body-on-frame architecture underneath the 2004-2008 F-150. The standard-wheelbase truck carries the internal code U324. The long-wheelbase Expedition EL is U354. Production ran 11 years without a full redesign, which is unusually long for this segment, and Ford used that time for one major hardware overhaul instead of several small ones.
That overhaul landed for the 2015 model year: the 5.4L Triton V8 was replaced by a 3.5L twin-turbo EcoBoost V6, the solid rear axle gave way to an independent rear suspension, and the Platinum trim joined the lineup for the first time. Everything from 2007 through 2014 is the Triton-era truck. Everything from 2015 through 2017 is the EcoBoost-era truck.
There were smaller changes inside that window too. The trim lineup shifted in 2011, when Ford added a base XL trim and folded the Eddie Bauer package into an XLT Premium option instead. King Ranch expanded its availability the year before that. None of these are the kind of dividing line the 2015 refresh represents, but they matter when you're comparing two trucks a few model years apart and wondering why the window sticker looks different.
| Powertrain | Years Available | HP/TQ | Transmission | MPG (Combined) |

Powertrain & Trim Breakdown
5.4L Triton V8 (2007-2014)
The Triton V8 is the truck most of this generation's reputation, good and bad, is built on. It's a torquey, simple, naturally aspirated engine with a lot of miles on the road, and owners on ExpeditionForum and Ford-Trucks.com describe two very different failure stories depending on how the truck was maintained.
The spark plug issue is the one to understand before anything else. This generation uses a two-piece Motorcraft plug where the ground electrode shield can corrode and carbon-weld itself to the aluminum cylinder head. At the roughly 100,000-mile plug change interval, the plug shears off during removal instead of unscrewing cleanly, sometimes leaving the shield and threads damaged in the head. Ford's own technical service bulletin, TSB 08-7-6, documents the failure and specifies hand-tool-only removal procedures for 5.4L 3-valve trucks built before October 9, 2007, which puts early-production 2007 and 2008 models at the highest risk. Forum-reported repair costs range from around $160 for a single-plug fix at an independent shop to $570-$1,000 for a full 8-hole thread repair using Time-Sert or Calvan inserts. Cheap heli-coil kits are widely called unreliable by ExpeditionForum members; the thread-insert repair holds up much better long term.
Cam phaser rattle is the second major Triton complaint, and it's a separate issue from the spark plugs. Worn cam phasers, tensioners, and timing chain guides produce a rattle or tick at cold start and sometimes at hot idle, usually traced back to sludge or infrequent oil changes starving the variable cam timing solenoids of pressure. Owners report onset as early as 50,000 miles on neglected examples. Replacing the phasers doesn't always fix it permanently. Multiple forum threads describe the tick returning within a year because the timing chain and guides were already worn and needed replacement too, not just the phasers.
The 6R80 six-speed automatic behind the Triton V8 has its own well-documented issue: torque converter shudder in the 25-45 mph light-throttle range, worse as the transmission fluid warms past 175-195°F. This is a platform-wide 6R80 problem shared with the F-150, not unique to the Expedition. A fluid and filter service with Motorcraft friction modifier resolves it in many cases; if the shudder persists, the torque converter itself needs replacing. Aftermarket friction-modifier additives marketed as a standalone fix show up often in forum threads, but owners who've been through the repair describe them as a temporary band-aid rather than something that solves the underlying wear.
None of this means the Triton V8 is a bad engine. Forum consensus on ExpeditionForum is that a well-maintained 5.4L can comfortably clear 200,000 miles, and the failure modes above are well understood enough that an experienced independent shop can spot the warning signs during a pre-purchase inspection. The risk isn't the engine design; it's buying one where the plugs were never touched and the oil changes were irregular.
Two NHTSA recalls specifically target the 2012 model year's transmission electronics. Campaign 12V190000 covers a transmission range sensor that can miscalibrate, preventing the truck from engaging reverse properly and disabling the correct PRNDL and backup lamp indication. Campaign 16V248000 covers an unexpected downshift to first gear regardless of vehicle speed, which can cause sudden deceleration and rear tire slide. Both were issued as free dealer remedies; run any 2012 Expedition's VIN through a recall check before you buy to confirm the work was done.
3.5L EcoBoost V6 (2015-2017)
The EcoBoost swap brought real gains: 55 more horsepower, 55 more lb-ft of torque, and a genuinely different driving character. Owners on ExpeditionForum who cross-shopped both engines describe the EcoBoost as quieter at highway speed and noticeably stronger off the line, though a few report real-world fuel economy dropping into single digits while towing a loaded travel trailer.
The most-reported EcoBoost complaint is a cold-start rattle, a two-to-five-second clacking noise on startup that clears once oil pressure builds, typically flagged by diagnostic codes P0016 or P0017 for cam position correlation. Independent shops and forum members trace it to two overlapping causes: cam phaser wear, and pivot pin stretch in this first-generation EcoBoost's single timing chain. It's a well-known enough pattern that Ford has addressed related versions of it in service bulletins on this engine family, though the fix scope has varied by production year, so don't assume every rattle needs the same repair without a proper diagnosis first.
Three separate NHTSA recalls apply to this era, and this is the detail some competing buying guides get wrong when they call 2015-2017 recall-free. Campaign 22V648000 covers the front blower motor, mounted behind the glove box, which can fail and increase the risk of an interior fire; Ford's filing cites 25 reported fires with 12 causing extensive vehicle damage. Campaign 22V150000, covering 2016-2017 trucks specifically, addresses a brake master cylinder that can leak fluid from the front wheel circuit into the booster, reducing brake function. Campaign 25V236000 covers a related brake master cylinder leak on 2017 models. And two rearview camera campaigns, 25V270000 (2015 models) and 25V572000 (2015-2017), cover a camera circuit board issue that produces a blank, distorted, or inverted backup image. None of these are catastrophic if caught, but all five should show as completed on a VIN recall check before you sign anything.
On the positive side, the towing numbers moved in the right direction with the swap. A standard-wheelbase EcoBoost Expedition is rated up to 9,300 lbs with the heavy-duty tow package, and the Expedition EL up to 9,200 lbs, both ahead of what the Triton V8 could pull with the same package. Owners cross-shopping the two engines for towing duty consistently pick the EcoBoost for that reason, even knowing fuel economy drops sharply under load.
Shared Across Both Engines
A handful of issues don't care which engine is under the hood. Front subframe and radiator support crossmember rust is a real risk on rust-belt trucks; forum threads describe rust-through at the crossmember bad enough to fail a state inspection, with one documented case near 95,000 miles running about $500 to repair. Ford's own reinforcement plates on some trucks can trap moisture underneath and make it worse rather than better, so a rust-belt example needs an underbody inspection regardless of which powertrain it has.
On 4x4 trucks, a clicking or grinding noise from the front hubs when the truck is in two-wheel-drive mode is usually a cracked vacuum line in the Integrated Wheel End (IWE) system, not a failed hub actuator. Check the vacuum lines first; it's a much cheaper fix than parts owners sometimes replace unnecessarily. And SYNC or MyFord Touch infotainment glitches, ranging from a frozen touchscreen to features going fully unresponsive, come up often enough in forum threads to be worth a full functional test on any test drive, though they're an annoyance rather than a safety issue.
Trim Levels
| Trim | Key Equipment | What to Pay Extra For |
|---|---|---|
| XL / XLT | Cloth or base leather, standard suspension, basic tech | The XLT Premium package if you want leather without jumping to Limited |
| Eddie Bauer (2007-2010 only) | Two-tone leather, roof rack, unique badging | Skip if condition is equal to a same-year Limited; largely a styling package |
| Limited | Leather, power third row, upgraded audio, adjustable air suspension on many builds | Worth it for the air suspension ride quality if you're prepared for the eventual repair |
| King Ranch | Limited's equipment plus unique leather, badging, and interior trim | Mostly cosmetic over Limited; pay for condition, not the badge |
| Platinum (2015-2017 only) | Top-tier leather, largest wheels, most driver-assist features available on this generation | The strongest overall equipment list if budget allows |
Limited, King Ranch, and Platinum trims commonly came with an adjustable air suspension, marketed as RIDE CONTROL, that XL and XLT trims typically did not have. It rides well when it works. Rear air springs are rubber and dry out over time, especially in cold climates, and a failed system shows up as the back end sagging while the front stays level. Compressor replacement runs roughly $400-700; individual air springs run about $100 each plus labor for two. A permanent alternative many owners choose is a coil-spring conversion kit, which trades the adjustable ride for a setup that can't fail the same way again, for less than the cost of replacing one original air spring.
Which Model Years to Target Within This Gen
| Year | Recalls (NHTSA) | Key Changes | Verdict |
|---|---|---|---|
| 2007 | 2 | Launch year, 5.4L V8, XLT/Eddie Bauer/Limited/King Ranch trims | Caution |
| 2008 | 4 | King Ranch trim expands availability | Caution |
| 2009 | 1 | Minor brake light switch recall only | Good value |
| 2010 | 0 | No NHTSA recalls on file for this model year | Good value |
| 2011 | 0 | XL base trim added, Eddie Bauer replaced by XLT Premium package | Good value |
| 2012 | 3 | Transmission range sensor and downshift recalls; confirm both were completed | Caution |
| 2013 | 0 | No NHTSA recalls on file, mature 5.4L V8 | Best value |
| 2014 | 0 | Final year of the 5.4L V8, most refined Triton-era truck | Best value |
| 2015 | 3 | All-new EcoBoost V6, independent rear suspension, Platinum trim debuts | Caution |
| 2016 | 3 | EcoBoost matures into its second model year | Good value |
| 2017 | 4 | Final year of this generation, most equipment available | Best overall |
2013 and 2014 are the sweet spot if you want the V8. The spark plug and cam phaser risks never fully disappear on this engine, but by the last two model years Ford's running production changes and a longer maintenance track record on individual trucks make it easier to find one that's already proven itself. 2017 is the sweet spot if you want the EcoBoost: it carries the most recalls of any year in this generation on paper, but that's a function of Ford covering more of the fleet with each campaign over time, not a sign the 2017 trucks were built worse. Every one of those recalls has a free dealer remedy. Confirm they were done and you're buying the most refined version of this generation.
Pre-Purchase Inspection Checklist
If you're looking at a 2007-2014 Triton V8:
- Start the truck stone cold. Listen for a rattle or tick from the front of the engine that fades within a few seconds as oil pressure builds. A tick that doesn't fade points to worn cam phasers or timing chain guides, not just a phaser needing service.
- Ask for maintenance records showing the spark plugs have been changed, and by whom. A dealer or a shop experienced with Triton engines using the correct removal procedure is a good sign. A truck with original plugs past 100,000 miles is a truck where the next owner inherits that risk.
- If it's a Limited, King Ranch, or Eddie Bauer with air suspension, check ride height front versus rear with the truck parked on level ground. A rear sag means the air springs or compressor need attention soon.
- On 4x4 models, put the truck in 2WD and listen for clicking or grinding from the front wheels while turning at low speed. Don't let anyone quote you a hub actuator repair before the vacuum lines have been checked.
- If you're in a rust-belt state, get the truck on a lift and inspect the front subframe and radiator support crossmember directly, not just a visual glance underneath.
If you're looking at a 2015-2017 EcoBoost:
- Cold-start it and listen for a two-to-five-second clack or rattle from the engine bay. Ask if it's ever thrown a check engine light for codes P0016 or P0017.
- Confirm the VIN's recall status for all five campaigns covering this era: the blower motor fire risk, both brake master cylinder campaigns, and both rearview camera campaigns. All have free remedies; there's no reason to buy one that hasn't had them done.
- Test the backup camera image directly. A distorted, blank, or inverted picture is the exact symptom the camera recalls address.
- Verify the blower motor and HVAC fan work correctly on all speeds; a failing unit is the specific defect behind the fire-risk recall.
Run every VIN through a recall check before you commit, regardless of which engine you're looking at.
Running Costs
| Powertrain | Combined MPG | Key Maintenance Items | Est. Annual Repair Cost |
|---|---|---|---|
| 5.4L Triton V8 | ~16 (2WD) | Spark plugs at 100k (budget for a thread-insert repair), timing chain service if phaser tick returns | Higher if spark plug or timing chain work is needed; otherwise moderate |
| 3.5L EcoBoost V6 | 17-18 (2WD) | Turbo-rated oil and filter on schedule, cold-start rattle diagnosis if it appears | Moderate; turbocharged maintenance costs more per service than the V8 |
The EcoBoost's real-world fuel economy is meaningfully better in mixed driving, per CarScout's EPA-sourced data for the 2016 model year: 18 mpg combined for a 2WD Expedition and 17 mpg combined for a 2WD Expedition EL, versus roughly 16 mpg combined for a comparable 2WD Triton V8 per EPA figures. That gap narrows or disappears while towing; several owners report EcoBoost fuel economy dropping to 8-9 mpg with a loaded trailer, similar to what the V8 delivers under the same load.
Both engines sit behind the same 6R80 transmission family, so torque converter shudder and fluid service intervals are a shared cost consideration regardless of which engine you choose.
FAQ
Is the 5.4L Triton V8 in the 3rd gen Expedition reliable? It's reliable with maintenance discipline. The two known risks, spark plug removal failure and cam phaser rattle, are both manageable if caught early and expensive if ignored. A truck with documented plug changes and clean oil-change history is a safer bet than one without records.
Is the 3.5L EcoBoost Expedition reliable? It's a stronger, more efficient engine than the V8 it replaced, but it carries its own risks: cold-start rattle from cam phaser and timing chain wear, plus five separate NHTSA recalls covering the blower motor, brakes, and backup camera. Confirm all five were completed before buying.
What year Ford Expedition should I avoid? No single year in this generation is a hard pass, but 2007 and 2008 carry the highest spark plug removal risk due to early production, and 2012 needs its two transmission recalls confirmed as completed. None of these disqualify a truck; they just mean extra diligence.
How many miles does a 3rd gen Expedition last? Owners on ExpeditionForum and Edmunds forums regularly report both engines passing 200,000 miles with consistent maintenance, including at least one documented EcoBoost example past that mark. Mileage alone isn't the risk factor here; unaddressed spark plug and timing chain issues are.
Should I buy the Triton V8 or the EcoBoost version? The EcoBoost is the stronger overall truck: more power, better real-world fuel economy, and a newer independent rear suspension. The V8 is the simpler, often cheaper option with a longer track record. Either is a reasonable buy with the right pre-purchase inspection.
Bottom Line
If you want the V8 era, target a 2013 or 2014 with documented spark plug and oil-change history. If you want the EcoBoost era, target a 2017 with all five recall campaigns confirmed complete on the VIN. Either way, the single most important thing you can check before buying is maintenance records, not mileage. Run the VIN through a recall check first.
