Buyable — only with the full 27-recall history in hand.

First year of the 14th generation, and it holds the recall record in our data: 27 campaigns, including a do-not-drive steering recall, three driveshaft campaigns, and an engine-replacement recall for 2.7L/3.0L EcoBoost intake valves. Complaint volume nearly doubled versus 2020.

A 2021 with every recall done can be a fine truck — but the burden of proof is on the seller.

EcoBoost intake valve failure (2.7L / 3.0L)

major
  • 2.7L & 3.0L EcoBoost

Intake valves can break and destroy the engine — recall 24V-635, born from federal investigation EA23002. Dealers run an engine cycle test and replace engines that fail it, free. On any 2.7 or 3.0 truck, confirm this test happened: it is the difference between a free engine and a catastrophic failure.

This is a 2.7L & 3.0L EcoBoost problem. The 3.5L EcoBoost V6 and 5.0L V8 don’t share it.

Transmission software: false neutralmajor

The 10-speed can suddenly shift to neutral from a false low-fluid-pressure code (recall 22V-188; botched fixes were re-recalled as 25V-169). Power train remains the top complaint category for this year. Any hesitation, loss of power, or neutral event on the test drive is disqualifying.

Recall software remedy

10-speed CDF clutch drum — the wear item no recall coversmajor

  • 10-speed automatic (all engines)

Beyond the recalled software faults, mechanic and owner communities document a hardware wear pattern in 2017–2023 10R80s: the CDF clutch drum. Transmission techs report seeing failures weekly, with rebuilds commonly appearing at 40,000–70,000 miles — roughly $2,500 for a remanufactured unit installed, $4,000+ for rebuilds — and the issue has drawn class-action attention. Ford revised the drum in production around August 2022, which means every 2021 predates the fix. Two defenses: Ford's 'lifetime' fluid is realistically good for about 60k of truck use, so do a Mercon ULV drain-and-fill every 30–60k (burnt, dark fluid is the tell — walk away or negotiate). And if shift quality has drifted rather than failed, it's often the transmission's adaptive learning, not hardware: a dealer reflash or a FORScan adaptive reset (a $20 OBD adapter) restores baseline and is the cheap first step before anyone quotes you a rebuild.

Driveshaft damage or fracturemajor

Three campaigns: two-piece driveshaft assembly errors (21V-381) and underbody insulators contacting the aluminum driveshaft (21V-986, expanded as 22V-623). A fractured driveshaft causes loss of power or loss of control. Verify all three by VIN.

Steering gear internal damagemajor

Recall 21V-407 was severe enough that Ford told owners to stop driving; affected trucks were towed in for steering gear replacement. The population is narrow, but verify by VIN.

Recall remedy

The long tail: wipers, trailer brakes, cameras, fuel pumpmoderate

Four wiper recalls (arms and motors), three trailer-brake software recalls (latest 26V-104, March 2026), rearview camera software (25V-315, phased), and a low-pressure fuel pump recall (25V-455) whose remedy was still pending as of mid-2026 — ask whether it has since been performed. Exterior lighting and electrical rank high in complaints, consistent with this electronics-heavy redesign — and mechanics point at a specific cause for the dead-battery reports: SYNC 4-era modules that fail to enter sleep mode, draining the battery overnight (one documented case: a dead battery at 31,000 miles cured entirely by a software update the dealer had never applied). Ask the dealer to check the VIN for outstanding software updates, and insist on a BMS reset with any battery replacement.

Before you buy

Print this
  1. 01A VIN recall check is mandatory — expect a long list, and get the dealer printout of completed work.
  2. 02On a 2.7 or 3.0 EcoBoost, confirm the engine cycle test (24V-635) was performed and passed.
  3. 03Ask whether the fuel pump recall (25V-455) remedy has been performed now that parts may be available.
  4. 04Test drive: any hesitation, loss of power, or neutral event is disqualifying.
  5. 05If it tows: verify all three trailer-brake software updates and the Max Tow axle hub recall (23V-896).
