The prices, and whose they are
We do not sell batteries or install them, so each figure below belongs to the business named beside it, read on October 25 or 26, 2026. The Fusion is better covered by the aftermarket than most hybrids in this series: one seller splits it into three generations of hybrid pack plus a separate plug-in pack, which is the right way to think about the car.
| Source and what it sells | What it lists |
|---|---|
| Best Hybrid Batteries — 2010–2012 Hybrid | $1,949, shown against $3,949; 3-year unlimited-mileage warranty, 6-year option; core return required |
| Best Hybrid Batteries — 2013–2015 Hybrid | $2,049, shown against $3,849; same warranty terms |
| Best Hybrid Batteries — 2016–2020 Hybrid | $2,149, shown against $3,949; same warranty terms |
| Ford EG9Z-10B759-FARM — remanufactured, 2013–2020 Fusion and MKZ | $3,224.71 MSRP, $3,037.03 sale on FordPartsGiant; core charge not shown; listed as unavailable because of a supply shortage |
| Best Hybrid Batteries — Fusion Energi 2013–2020 | $4,849, shown against $8,549; the listing states no warranty or installation terms |
Two things stand out. First, Ford’s own replacement for the lithium-ion hybrid is a remanufactured pack, not a new one, and it costs roughly a thousand dollars more than the aftermarket version before labor. The listing also says it cannot currently be ordered, so a dealer quote may come back with a long wait or a different part. Second, the Energi price sits in a different class from the hybrid packs, as it should: the plug-in pack holds several times the energy.
What we could not verify: a RepairPal estimate for this job (none surfaced), a price for a new rather than remanufactured Ford pack, any Ford part price for the Energi pack, and the labor hours a dealer charges. One reconditioner’s page refused our fetch, so its price is not here. Treat labor as a separate line on every quote and ask for it in writing.

Three Fusions with a big battery, three different parts
The Fusion Hybrid arrived for the 2010model year. Its pack was nickel-metal hydride: the federal fuel economy record for the 2011 car lists a 275-volt Ni-MH battery. That first-generation design carried through 2012 and is the oldest Fusion pack on the road, which is why most of the “my hybrid is dying” stories now come from these cars.
The 2013redesign switched chemistry. The same federal records list the 2015 and 2018 Fusion Hybrids with a 280-volt lithium-ion battery, and Ford carried that layout to the end of production in 2020. The aftermarket splits it into 2013–2015 and 2016–2020 listings, while Ford’s remanufactured part number covers the whole 2013–2020 span. Ask any seller which one fits your build, and make them check the VIN rather than the badge.
The third car is the Fusion Energi, a plug-in hybrid sold from 2013. Clean Fleet Report gave its usable capacity as 7.6 kWh through 2018 and 9.0 kWh for 2019, from 84 lithium-ion cells in a pack of the same size; the federal fuel economy record gives the 2019 Energi a 26-mile electric range. Ford’s recall filings describe the 2019–2020 pack the same way, 84 cells, and report fires in the trunk area. An Energi quote and a Hybrid quote are not comparable numbers.
The 2019–2020 Energi: a pack Ford replaces for free
This is the part of the Fusion story with no parallel in the Toyota and Honda posts. In June 2023 Ford filed safety recall 23S33, NHTSA number 23V440, on 2019–2020 Fusion Energi cars built between December 2017 and July 2020. The defect, in Ford’s words to NHTSA, is a current interrupt device tripping inside a high-voltage battery cell, which pushes excess voltage and current through the battery energy control module (BECM). The result can be a loss of drive power or a fire near the BECM. Ford’s chronology counted seven fires and 270 warranty claims for loss of power by May 2023.
Later filings named the root cause: gas building up in one or more of the 84 cells as electrolyte depletes, which Ford said develops with several charge cycles a day, charging to and parking at 100% charge, or simply two or more years in service. The final remedy is a new high-voltage battery plus BECM software that lowers the maximum state of charge, at no cost to the owner. Ford also offered, for a limited time, to buy cars back at the original price less depreciation, plus a 15% premium.
The fix took a long time. Owners were told in 2023 to stop charging. A June 2024 owner letter described an interim repair, a fuse block between the battery and the BECM and a software change that disables plug-in charging, so the car runs as an ordinary hybrid. Ford’s March 18, 2025 dealer notice finally said parts and software were available for the replacement battery. Federal complaints filed against these years read like a log of that wait.
Energi packs outside the recall
A 2013–2018 Energi is the expensive case. It has the larger plug-in pack, it is not in 23V440, and every one of them is now past Ford’s eight-year term on age. The only listed price we found is the aftermarket $4,849 above, with no warranty terms on the listing, and one seller covering 2013 through 2020 under a single product should prompt a question about whether it suits the 9.0 kWh 2019–2020 pack at all.
Before paying for a pack on one of these cars, rule out the cheaper faults Ford has documented. A 2015 bulletin for 2013–2015 Energi cars covers open battery cooling fan fuses F35 and F36 and intermittent 12-volt drain. Several bulletins cover battery charging failures with particular 120-volt charge cords, and a 2018 recall (18V592) replaced 120-volt cords on 2013–2015 Energi cars because some lacked a thermistor and could overheat. A car that will not charge is not automatically a car with a dead pack.
First-generation cars that drift onto gas
The most common complaint from 2010–2012 owners is not a car that will not start but one that quietly stops behaving like a hybrid. Ford put a name to it. Its April 2023 bulletin, TSB 23-2098, says these cars may see reduced electric operation and more gasoline engine running “around 10 years of vehicle age and beyond,” and blames software in the BECM and powertrain control module. The fix is a reprogram of both, with a half-hour labor allowance.
Ford also ran it as a program, 22G04, in September 2022: free BECM and PCM software updates for 2010–2012 Fusion, Milan and MKZ hybrids, with no mileage limit until September 30, 2023, and after that only for cars under 150,000 miles and 10 years in service. In 2026every first-generation car is past that age, so the free program has lapsed, but the bulletin has not. A shop that quotes a pack on a 2010–2012 car that runs but leans on its engine should first confirm the software level. Federal complaint narratives from 2011 owners describe exactly this symptom.
When the fault is the battery’s computer
The BECM sits on the pack and decides how it charges and discharges. It fails, or needs new software, more often than the cells do, and its codes look alarming. Ford’s service messages over the years include BECM reprogramming for a red-triangle no-start on 2013–2014 Fusions, a separate no-start with code P0AE5 on 2013–2018 Fusion Hybrid and Energi cars, and BECM replacement on 2010–2012 cars that threw a “stop safely now” warning in extreme heat. Ford’s 2017 warranty guide lists the BECM, the battery pack fan assembly and the pack sensor module as covered hybrid components alongside the battery itself.
The practical rule: a hybrid warning is a diagnosis to be made, not a part number to be ordered. Ask what codes were stored, whether a Ford bulletin matches them, and whether the BECM was updated or tested before anyone quotes cells.
Ford’s warranty clock
Ford’s support page puts hybrid and electric unique component coverage at 8 years or 100,000 miles from the warranty start date, whichever comes first, and says the high-voltage battery is not covered if improper storage damaged it. The 2017 warranty guide adds a footnote that matters in some states: on vehicles certified as AT PZEV, the high-voltage battery is covered for 10 years or 150,000 miles where California’s AT PZEV rules are enforced. That guide names California, Connecticut, Maine, Maryland, Massachusetts, New Jersey, New York, Rhode Island and Vermont, with Oregon adopting the battery term only. It also says normal lithium-ion capacity loss is not a defect.
| Fusion years | Pack coverage in 2026 |
|---|---|
| 2010–2012 Hybrid | Out. Even a late 2012 is about 14 years old, past both the 8-year and 10-year terms. |
| 2013–2016 Hybrid and Energi | Out on the 8-year term. A late-sold 2016 in an AT PZEV state may sit at the end of a 10-year term; check its own guide. |
| 2017 Hybrid and Energi | Out on 8 years nationally; in an AT PZEV state the 2017 guide's 10-year term runs toward 2027 if the miles allow. |
| 2018–2020 Hybrid | Possibly in. A 2020 delivered new in 2020 is covered toward 2028, mileage permitting. |
| 2019–2020 Energi | Recall 23V440 replaces the pack regardless of warranty status. |
The in-service date, not the model year, starts the clock, and only the 2017 guide was read for this post. Our Ford warranty check by VIN page explains how to find the date and the remaining term.
What the Fusion complaint file can and cannot say
Our corpus holds 22,285 NHTSA complaints against the 2008–2020 Fusion, a snapshot pulled in August 2026; the live federal file has grown slightly since. NHTSA lists the car under several names, Fusion, Fusion Hybrid, Fusion Energi and Fusion HEV, and our pull merges them. It cross-lists many complaints under more than one name, too, so there is no clean way to separate the hybrids. Nothing here is a count of failed packs. Each model year keeps its five most-reported components; a category missing from a year is below that year’s fifth, not absent.
Within those top fives, the electrical system accounts for at least 1,104 of 19,926 counted reports, or 5.5%, and it appears in 8 of 13 model years. The all-hybrid Prius puts 10.6% of its counted reports on the electrical system, with the category in 15 of 15 years, about 1.9times the Fusion’s share. The Fusion’s file is dominated by other things: steering in the early cars, engine and power train later, which our Fusion transmission replacement cost post takes apart.
The first-generation hybrid years barely register. Among 2010–2012, the electrical system reaches the top five only in 2012, and it first appears anywhere in the Fusion record in 2012. After that it holds a place in most years, missing only 2015. Read against the Camry’s pooled file, that is the usual shape for a mixed nameplate: a modest, steady electrical slice that a battery problem could sit inside without being visible.
Where the electrical share jumps
The chart above measures something slightly different: electrical complaints as a share of each model year’s total. From 2013 through 2018, in the years where the category makes the top five, that share runs between 8.2% and 12.3%. Then it jumps. In 2019 the electrical system is 141 reports, 30.5% of the year. In 2020 the electrical system is 79 reports, 34.6% of the year. 2020 is the only Fusion year it leads.
Those two years are exactly the ones recall 23V440 names. On the RAV4 the same kind of chart showed an electrical signal that predated the hybrid and had nothing to do with the pack. On the Fusion the timing lines up with a real battery campaign, and reading the narratives filed under the electrical system for 2019 and 2020 supports it: the subject that keeps recurring is the Energi recall, with owners describing a car they were told not to charge, a repair part that was not available, or a loss of power.
That is still not a failure rate. The same years also carry complaints about lighting, backup cameras and 12-volt batteries, gas and hybrid Fusions sit in the same rows, and the recall itself prompts filings. What the record supports is narrower and more useful: if you are looking at a 2019–2020 Fusion with a plug on the fender, the recall status is the first thing to settle. Our Ford Fusion years-to-avoid breakdown scores every model year on its whole record.
Recalls, checked against a known positive
On October 25, 2026 we queried NHTSA’s recall API for the “Fusion,” “Fusion Hybrid,” “Fusion Energi” and “Fusion HEV” models for every year from 2010 through 2020. One campaign replaces a traction battery: 23V440, listed under the plain “Fusion” model for 2019 and 2020 and filed under the traction battery management system. Two others touch the plug-in hardware without replacing the pack: 19V099, a cover over exposed high-voltage fuses on 2019 Energi cars, and 18V592, the 2013–2015 Energi charge cords.
An empty result only means something if the query can find a hit. Here it does twice: the same query returns 23V440 for the Fusion itself, and the 2012 Prius returns two hybrid propulsion campaigns. No 2010–2018 Fusion Hybrid campaign replaces a pack. Note that 23V440 does not show up under “Fusion Energi” in the API, only under “Fusion,” so a search by the wrong model name can miss it.
That is the strongest argument for searching by VIN instead. Our Ford recalls by VIN page shows how, and buying a car with an open recall covers what to do if 23V440 comes back open on a car you are negotiating for.
The 12-volt battery that looks like a hybrid failure
Every Fusion Hybrid and Energi also carries an ordinary 12-volt battery that powers the computers and closes the high-voltage contactors. When it is weak the car may not reach ready mode, which looks like a hybrid fault. Search results blur the two: Kelley Blue Book’s “battery replacement” page for the 2018 Fusion Energi shows no fair repair range at all and a $45–$250 range for a car battery in its FAQ. That is a 12-volt price. Ford also has a service message on 12-volt drain caused by third-party phone apps on some 2013-and-later cars with an activated modem.
- Test the 12-volt battery first; it is a purchase in hundreds, not thousands.
- On a 2019–2020 Energi, run a recall check on the VIN before anything else.
- On a 2010–2012 car that leans on its engine, ask whether the BECM and PCM software matches TSB 23-2098.
- Ask which pack the quote is for: NiMH, lithium-ion hybrid, or Energi plug-in, and get it written down.
- Ask whether the price includes labor, and whether a core charge applies if the old pack is not returned.
For the first item, our battery size by VIN page matches the group size.
If you are shopping a used Fusion Hybrid or Energi
The model year sorts the risk more than the mileage does. A 2018–2020 Hybrid may still have pack coverage left. A 2013–2017 Hybrid has aged out nationally, so budget the aftermarket price above plus labor as a known possible cost. A 2010–2012 car is the oldest pack on the road, and its software fix is worth confirming before you trust a test drive. A 2013–2018 Energi carries the most expensive pack with no recall behind it; a 2019–2020 Energi is fine to consider only once the recall is done.
The Fusion’s main rival makes a useful comparison: our Camry Hybrid battery cost post covers Toyota’s pack and its longer warranty from 2020. A free Ford VIN decode confirms year, trim and powertrain, and the recall check shows whether 23V440 is open. Neither tests pack health, and a CheckerVIN report does not include accident, title or odometer history. A pre-purchase inspection at a shop that can read hybrid battery data is the honest route for that.

Frequently asked questions
How much does a Ford Fusion Hybrid battery replacement cost?
Best Hybrid Batteries lists aftermarket Fusion Hybrid packs at $1,949 for 2010-2012, $2,049 for 2013-2015 and $2,149 for 2016-2020, each with a three-year warranty and installation extra. Ford's own remanufactured pack for 2013-2020 cars (EG9Z-10B759-FARM) shows a $3,224.71 MSRP on FordPartsGiant, which also lists it as unavailable. Those are their figures, retrieved October 2026. The Fusion Energi plug-in pack is a separate, larger part.
Does my Fusion Hybrid have a nickel-metal hydride or lithium-ion battery?
By model year. The federal fuel economy records list the 2011 Fusion Hybrid's battery as 275-volt nickel-metal hydride and the 2015 and 2018 cars' as 280-volt lithium-ion. The first-generation Fusion Hybrid ran 2010-2012; the redesigned 2013-2020 car uses lithium-ion. The Fusion Energi plug-in uses a larger lithium-ion pack. The packs do not interchange, so confirm the model year and trim from the VIN before ordering.
Is the Ford Fusion Energi battery covered by a recall?
For 2019 and 2020 Fusion Energi cars, yes. Ford safety recall 23S33 (NHTSA 23V440) found that a cell fault inside the high-voltage battery can damage the battery energy control module, causing loss of power or a fire in the trunk area. The final remedy is a new high-voltage battery and a software update at no charge, and Ford told dealers in March 2025 that parts were available. 2013-2018 Energi cars are not part of that recall.
What is Ford's hybrid battery warranty on a Fusion?
Ford's hybrid and electric unique component coverage runs 8 years or 100,000 miles from the warranty start date and includes the high-voltage battery and its control module. Ford's 2017 hybrid warranty guide adds that in states enforcing California's AT PZEV rules, the high-voltage battery is covered for 10 years or 150,000 miles. Check the warranty guide for your own model year and the emissions label on the car.
Do Fusion Hybrid batteries fail often?
The federal complaint file cannot say directly, because it pools gas, Hybrid and Energi Fusions. Across 2008-2020 the electrical system is 5.5% of counted top-five reports, against 10.6% for the all-hybrid Prius. The exception is 2019 and 2020, where electrical complaints jump to at least 30.5% of each year's total; those are the model years of the Energi battery recall.
