Ford Recalls 741,000 Trucks and SUVs Because the Transmission Can Break Its Own Parking Lock

Here’s the short version: on 741,195 of Ford’s biggest trucks and SUVs, the transmission can damage the exact part that keeps the vehicle from rolling away — and then one day you shift into Park, walk away, and it doesn’t hold. If you own one of these, that isn’t a someday problem. That’s a “the 6,000-pound truck in my driveway could roll into the street” problem.

Let me walk through what the federal filing actually says, because on this one the mechanism is the whole story.

What’s actually failing

Every vehicle in this recall runs Ford’s 10R80 — the 10-speed automatic — with park-by-wire, meaning there’s no mechanical cable from the shift lever to the transmission. When you select Park, a computer commands a small hardened-steel finger called the parking pawl to drop into a toothed gear and physically lock the driveline. That pawl is the entire reason a parked vehicle stays put.

The defect: under certain commanded shifts, that pawl can engage while the vehicle is still moving. Dropping a locking pin into a spinning gear is exactly as violent as it sounds. The impact can grind the pawl down, bend it, or shear it off completely. And here’s the part that makes it dangerous — it usually doesn’t fail right then. The pawl gets damaged now, the truck drives away fine, and then some later day you put it in Park on a grade, the damaged pawl can’t hold the weight, and it rolls. NHTSA’s own language: “Park system damage may result in a vehicle rollaway, increasing the risk of a crash.”

So this is not a check-engine-light recall. It’s a rollaway recall, and the damage that causes the rollaway may already be done before you notice anything is wrong.

The vehicles, and what owners were already reporting

NHTSA campaign 26V402 covers five nameplates, all built on the same rear-drive architecture around the 10R80:

• 2018–2021 Ford Expedition and 2018–2021 Lincoln Navigator
• 2020–2021 Ford Explorer and 2020–2021 Lincoln Aviator
• 2021 Ford F-150

That’s 741,195 vehicles. And the transmissions on these trucks weren’t a clean record going in. Across the exact vehicles named in this recall, owners have already filed 1,488 powertrain complaints with NHTSA. Here’s how that breaks down on the highest-volume models — pulled from our copy of the federal complaint database:

Powertrain-category complaints (engine, transmission, and driveline) on the exact recalled model years; “median failure mileage” is the odometer reading where owners most often reported a powertrain problem. The Lincoln Navigator and Aviator carry lower volumes but the same 10R80.

Notice where those medians land — many of these failures cluster between 40,000 and 78,000 miles, which is squarely in used-truck, second-owner territory. Whatever the software was doing, drivers of these vehicles have been feeling their transmissions misbehave for a while.

Ford, for its part, told regulators it is aware of 24 allegations of property damage and 9 alleged injuries — two of them emotional — tied to this defect as of the filing. Property damage is what a rollaway looks like on paper: the vehicle rolled into something.

The part that should bother you: the timeline

The recall was filed June 24, 2026. Interim letters — the “your vehicle has a safety defect, here’s the risk” notice — go out August 3, 2026. But the actual remedy, a powertrain-control-module software update plus inspection and replacement of any park components already damaged, is not expected to be available until April 2027.

Read that again. Ford is telling three-quarters of a million owners that their Park might not hold, and the fix is the better part of a year away. There’s an engineering reason — the shift software has to be recalibrated and validated so it stops commanding the pawl at the wrong moment — but it means that for now, the job of not getting hurt falls on you.

How to tell if your park lock is already damaged

The failure hides, so learn its tells. Watch for:

• A hard clunk or metallic bang when you shift into or out of Park, especially if it’s new or getting louder.
• The vehicle rolling, creeping, or settling a few inches after you’ve shifted to Park and taken your foot off the brake — that’s the damaged pawl not fully holding.
• A grinding or ratcheting sound as you come to a stop and select Park.

Any of those, treat as the pawl telling you it’s been hurt. Set the parking brake, chock a wheel if you’re on a slope, and get it to a dealer for inspection under the recall.

What this means if you own one

You don’t need to stop driving it. You do need to change one habit, starting today.

1. Use your parking brake every single time. This is the whole game until the fix lands. The defect attacks the transmission’s park lock — your parking brake is a completely separate mechanical system. Set it whenever you stop, on any grade, before your foot comes off the brake. Make it automatic. On these vehicles it is now your primary defense against a rollaway, not a backup.
2. Run your VIN. Check it at nhtsa.gov/recalls against campaign 26V402. Recall repairs are free, regardless of where you bought the vehicle. Ford’s customer line for this one is 1-866-436-7332.
3. Document everything. Because the fix is nearly a year out, keep dated records of any symptom and every dealer conversation. If the pawl is already damaged, you want it inspected and replaced under the recall — not waved off.

We track the full recall and complaint record for these trucks by model year — the 2020 Ford Explorer, 2021 Ford F-150, 2018 Ford Expedition, and 2018 Lincoln Navigator each have their own page with the NHTSA campaigns and owner reports laid out. If you’re shopping a used one, that’s where I’d start before you sign anything.

The honest take

The cause here is software — the transmission’s own shift logic commanding the parking pawl at a moment it never should. That’s fixable with a reflash, and Ford is doing exactly that. But two things keep this from being a shrug. First, the software may have already broken hardware: a pawl that’s been ground down or sheared doesn’t get healed by new code, which is why the remedy includes inspection and replacement. Second, the wait is long. A rollaway is one of the few failure modes that can hurt someone when nobody is even in the vehicle, and “we’ll have the fix by spring” is a lot to ask of an owner who parks on a hill every day until then.

Set the parking brake. Every time. Then get the recall done the day it’s available.
