Ford 1.0 EcoBoost Wet Belt: Is Your Car in the Recall?

The Ford wet belt story is about one engine: the 1.0-liter three-cylinder EcoBoost, which Ford's US documents name in the Fiesta, Focus and EcoSport. One US recall on it covers 147,170 vehicles in its June 22, 2026 supplement.

A separate federal investigation into sudden engine failure is still open, and it's about a different belt.

It's easy to muddle, and understandably so: the engine has two separate belts running in oil, they fail in different ways, and they're the subject of two different pieces of regulatory action. Owners have read a headline about "the wet belt recall", checked that their car is a Focus, and concluded they're covered when they aren't.

Ford 1.0 EcoBoost wet belt: which belt do people mean?

The one thing to take from this page is that a Ford wet belt problem can mean either of two belts, and each fails in its own way:

• The timing belt keeps the crankshaft and camshafts in step. Its failure mode is degradation: the belt sheds material, the debris blocks the mesh screen over the oil pump pick-up, oil flow falls, and the engine can be damaged or seize through lack of lubrication.
• The oil pump drive belt is a second, smaller belt that drives the oil pump. Its failure mode is mechanical: Ford's recall says the tensioner arm can fracture or separate, or the belt can degrade and shed pieces. Lose drive to the oil pump and pressure doesn't decline gradually.

Both sit in engine oil and both end in oil starvation. But they're different parts, with different fixes and different regulatory status, which is why "is my car in the recall?" has a more complicated answer than a model-year list gives.

The belt you can reach

The general mechanism is explained further in how a wet belt engine fails.

Which cars does the Ford recall cover?

Ford's safety recall 23S64, filed with NHTSA as 23V-905, is an engine oil pump belt inspection. Its scope, in Ford's own technical instructions, is:

Note the transmission condition. Manual-transmission cars are not in this recall, which has confused a great many owners, because the engine is the same.

There's a second trap, and it's worse, because it makes a covered car look uncovered. NHTSA's own recall lookup doesn't return this campaign for a Fiesta.

We checked on August 27, 2026: a 2019 Fiesta returns three recalls and 23V-905 isn't among them, while a 2020 and a 2022 EcoSport both return it.

Ford names the Fiesta in the technical instructions' title line and again in the dealer letter's build table. So a Fiesta owner who does the sensible thing, types their car into the federal lookup, is told nothing.

Ford's own owner page for the campaign closes that gap in the wrong direction. It's headed 2016-2022 Ford EcoSport and Focus 1.0L Engine and names no Fiesta anywhere, so the two surfaces an owner would actually check both leave the car out while the engineering document puts it in.

Read September 6, 2026.

The same check cuts the other way on the EcoSport. Ford's title line stops at 2021, but NHTSA returns the recall for a 2022 car, and Ford's own build table runs to December 2021 production.

If your car sits near either edge, the VIN is the only answer that means anything, and a model-year list, including the one above, is a starting point. Our free VIN checker shows the open recalls on yours.

What does the recall actually do to the car?

The service procedure is worth reading as an owner, because it tells you what a dealer is actually instructed to do. The technician drains the oil and looks for metal or debris.

If debris is found, the oil pan comes off and the oil pump cover is removed to inspect the drive belt.

And if that belt is broken or damaged, the instruction is to install a new long block engine and turbocharger.

That's the interim repair for a damaged oil pump belt found at inspection: an engine, not a belt. The final remedy, with owner letters mailed August 11, 2025, replaces the oil pump belt and its tensioner, and Ford's June 2026 supplement allows 9.7 to 10.2 hours for doing the timing belt in the same job.

Ford's own recall page carries the half the technical instructions leave out. Parts for the final repair were scheduled for the first quarter of 2025, on a recall filed on December 22, 2023, and in the meantime Ford authorized dealers to replace the engine assembly of any car whose engine had already failed from the oil pump belt or its tensioner, as an interim repair, free of parts and labor.

So the scale of the remedy is real. For the owners at the front of the queue it was also the only thing there was to fit.

What is the timing belt investigation about?

Separately, NHTSA opened a preliminary evaluation into the 1.0 EcoBoost in late 2025 and upgraded it to an engineering analysis on July 31, 2026. An engineering analysis is the more serious of the two stages, and it's the step that can precede a recall.

The reported scope began with 2015-2017 Fiesta and 2015-2018 Focus fitted with the 1.0 EcoBoost and manual transmissions (the population the earlier recall left out) and was later widened to take in 2018-2021 EcoSport and 2016-2018 Focus with automatics.

Two figures from the investigation record carry the case. Failures are averaging 70,000 miles, and 98% happened before 150,000 miles, which was the mileage at which Ford originally told owners to replace the belt.

On the original schedule, in other words, the large majority of these engines were failing before the maintenance that was supposed to prevent it.

That's why it escalated.

This is live. An engineering analysis can end in a recall, an extended scope, or no action at all.

Anything you read about scope (here included) is a snapshot, so check the current status against your VIN.

What does a Ford wet belt failure look like from the driver's seat?

It depends which belt goes, and that's the one place the two federal actions separate cleanly for a driver.

The oil pump belt announces itself. Ford's own description of the recall condition is that the tensioner arm may fracture or separate, causing a loss of vehicle power and power braking assist, which is the wording that makes this a safety recall rather than a warranty matter.

Losing the engine while moving takes the brake servo with it, and the pedal goes hard.

We counted what owners of one car actually described. Of those 42 complaints:

Read that column as an order of events rather than a menu. The warning light, the lost power and the tow tend to arrive together, and nearly half the owners say the engine was already gone, while only 9 heard a noise first.

The timing belt is the quiet one, and that's what makes it worse. It sheds material for years without changing how the car drives, and the first thing that reaches the driver is the same oil pressure light, arriving at the end of the sequence rather than the start of it.

So there's no early symptom to wait for on either belt. What decides the outcome is the VIN check and the service interval, which is why both of those come before anything else on this page.

How did this unfold?

The dates matter because the investigation's scope widened and the maintenance advice was cut, so what was true about your car in 2023 may not be now. This Ford wet belt timeline runs from 2013 to July 2026, oldest first:

1. 2013 onward The 1.0 EcoBoost three-cylinder spreads across Ford's small-car range, with a timing belt running in oil and a published replacement interval of 150,000 miles.
2. December 2023 Ford files safety recall 23S64 with NHTSA, on the oil pump belt.
3. Q1 2025 The quarter Ford told owners remedy parts would be available. Three belt complaints filed after that describe being turned away because the parts still weren't.
4. Late 2025 NHTSA opens a preliminary evaluation into the timing belt.
5. June 2026 Ford tells NHTSA it is cutting the recommended belt interval to 100,000 miles or six years; its US program 26L02 follows on August 25.
6. July 2026. Where it stands NHTSA upgrades the investigation to an engineering analysis and widens its scope.

What did Ford change in 2026?

On June 2, 2026 Ford told NHTSA about a global customer satisfaction program for vehicles with the 1.0-liter engine, cutting the recommended timing belt replacement interval from 150,000 miles to 100,000 miles or six years.

Read that as a manufacturer revising its own advice down by a third on an engine already under federal scrutiny. For an owner it has a practical consequence: if you bought the car believing the belt was good for 150,000 miles, the schedule you were working to no longer exists.

A six-year clock also means low-mileage cars are affected. A 2019 car that has covered 40,000 miles is past the time limit even though it's nowhere near the mileage.

The American version of it

The US paperwork arrived later and it's worth reading, because it settles something the rest of this page has to argue around. Customer Satisfaction Program 26L02, dated August 25, 2026, sets the same limit for American owners and names 146,945 vehicles.

That's close to the recall's latest count of 147,170, but the two documents cover different cars. The recall is for automatics only, while 26L02 has no transmission condition and different years.

It also names the cars, and the 26L02 program covers three Ford models by build date rather than by model year alone:

• Fiesta, 2014 to 2017, built at Cuautitlan.
• EcoSport, 2018 to 2021, built at Chennai.
• Focus, 2015 to 2018, built in Michigan.

The Fiesta on that list is the 2014 to 2017 car built in Mexico. The recall's Fiesta is the 2017 to 2018 automatic built in Cologne, so this list doesn't settle whether the recall covers a Fiesta; the document panel below sets out that contradiction.

Ford's own account of why sits in the bulletin, and it's a chain rather than a single fault: poor oil quality, contaminant buildup, rising oil acidity and irregular maintenance damage the belt; the shed material clogs the oil pump pick-up screen; oil pressure is lost; the engine seizes. That's the same sequence the recall describes, arriving by maintenance rather than by a broken tensioner.

There's money in it, if you kept the receipts

What 26L02 carries is a refund, not a free belt, and Ford mails the offer rather than calling: Ford will reimburse an engine repair or replacement you already paid for, where the failure traces to the belt. The Ford wet belt refund has four specific conditions, and all of them have to hold:

• The repair is dated before September 14, 2026.
• At that date the car was under 10 years old and under 150,000 miles from its warranty start.
• The repair order shows either an oil pressure problem traced to belt degradation, or one of five codes: P0016, P0017, P0018, P0019, P033F. Ford accepts either, and the wording matters if your invoice names a symptom rather than a code.
• You can show the last three oil changes before the failure, on schedule and with the right oil. Ford allows three months or 1,800 miles of slip and no unapproved lubricant.

The claim goes in within a year of your letter, with original receipts, through a dealer or by mail to Ford.

Read the third and fourth conditions together and you have the shape of it. The refund is real, and it's gated on paperwork most owners of a Fiesta nine years old or more won't have kept.

If you have it, take it to a dealer before the program expires on August 31, 2027. Owners Ford has already helped with a timing belt engine repair are excluded.

One more line in it is worth knowing even if you claim nothing: if the belt has already been replaced, the new six-year clock starts from that repair, not from the day the car was built.

The number that doesn't decide it

Not every 1.0 EcoBoost has a wet camshaft belt

Ford changed the engine before it changed the interval. A chain-driven version of the 1.0 EcoBoost was phased in from 2018, and every 48V mild-hybrid version uses one.

Both of the published reference lists we rely on agree on that, and it's why the Puma, which arrived after the change, isn't the car this page is about.

Two things stop that being the end of it. The chain replaced the camshaft belt, not every belt: the revised engine still drives its oil pump with a small belt running in oil, which is the part the recall above is about.

And belt and chain versions overlap by build date rather than by model year, so a 2018 or 2019 car can be either.

That's the same VIN question as everything else on this page.

What does this cost you?

Three scenarios, and the gap between them is the whole reason to pay attention.

The maintenance figure is our arithmetic, not a survey. Ford's recall labor table allows 9.1 hours on a Focus or Fiesta and 9.7 on an EcoSport to replace both belts and the tensioner, and we multiply that by the $132 US average shop rate.

It's a sense of scale, not a quotation, and the belt kit, seals and oil come on top. The full working, with what a failed engine adds, is in what a wet belt costs to replace.

The last row is the one that decides whether this matters, and it's worth seeing why the bill is an engine rather than a belt. The belt rarely snaps, and instead a degrading Ford wet belt takes the engine with it in five stages:

1. The belt degrades. It sits in engine oil for its whole life, and sheds material as it goes.
2. The debris reaches the oil pan. Shed rubber ends up where everything in an engine ends up.
3. The pick-up screen blinds over. The mesh guarding the oil pump catches the debris, then keeps catching it.
4. Oil pressure falls. Bearings that survive on a film of oil start running marginal.
5. The engine goes. Bearing failure or seizure, and the fix is an engine rather than a belt.

Nothing reaches the driver until step four. A failing dry belt whines for weeks; this one is silent.

Before you accept any quote for this job, read it properly. It's a long labor operation and the hours are where the money is.

Should this put you off buying one?

Not by itself, but it changes what you're buying. A 1.0 EcoBoost with a documented belt change, correct-specification oil and a clean VIN check is a perfectly sensible small car.

The same car with no paperwork is a lottery ticket where the losing outcome is an engine.

The full buying checklist, including what to look at in the oil and what to ask the seller, is in the wet belt buying checklist.

What should you do if you own one?

If you own a Ford with the 1.0 EcoBoost wet belt, do these five things, and the first settles whether the rest of this page applies to your car at all:

1. Run your VIN through a Ford dealer, Ford's own recall page or the NHTSA lookup. Free, and it takes minutes. This is the only answer that applies to your car rather than to a model year, and it surfaces any other open campaigns you didn't know about.
2. Work to the new interval, not the old one: 100,000 miles or six years, whichever arrives first. On a low-mileage car, the years will get there long before the miles.
3. Use the oil specification in your manual. On US cars Ford's current oil chart lists WSS-M2C970-A1, a 5W-20, and Ford's US manual accepts a 5W-20 with the API certification mark as the alternative. See the wet belt oil guide.
4. Shorten the oil interval if you do short cold trips. Fuel dilution attacks both the oil and the belt sitting in it.
5. Keep every receipt. Warranty, goodwill and any future campaign all turn on evidence that the car was maintained to schedule.

Common questions

Asked most often

Is there a recall on the Ford 1.0 EcoBoost?

Yes: US recall 23S64, filed with NHTSA as 23V-905. It covers the oil pump belt on 2017-2022 EcoSport, 2016-2018 Focus and 2017-2018 Fiesta with the 1.0 EcoBoost and an automatic. Manual cars aren't in it. Ford's own owner page names only the EcoSport and Focus, so check the VIN rather than either list.

Which Ford models have the wet belt?

Ford's US documents name the 1.0 EcoBoost three-cylinder in the Fiesta, Focus and EcoSport. The Puma carries the same engine but arrived after Ford moved to a chain, so it isn't part of this. Because engines varied by market and build date, a VIN check is the only reliable confirmation for your car.

How often should the Ford 1.0 EcoBoost belt be changed?

Ford cut the recommended interval to 100,000 miles or six years in June 2026, down from 150,000 miles. The six-year limit catches low-mileage cars long before the mileage does.

What happens if the Ford wet belt fails?

Belt debris blocks the oil pump pick-up screen, oil pressure falls, and the engine can be damaged or seize. From the driver's seat that is an oil pressure warning light. Ford's interim repair for an engine that already failed from the oil pump belt is a new long block and turbocharger.

Is the Ford 1.0 EcoBoost a good engine?

It's economical, refined for a three-cylinder and won awards. The belt design is its weakness, and a car with a documented belt change and correct-specification oil is a very different proposition from one without.

The federal investigation described here was open at the time of writing and its scope can change; recall coverage varies by market. Always confirm current recall and campaign status for your own VIN with a franchised dealer.
