Fusion engine complaints by model year
The 2018 model year has the most engine complaints by far, followed closely by 2019. The 2020 model year has far fewer, but it has also had less time on the road to collect them, so a low count there is not proof of a better engine. The same coolant failure appears in all three years, and 2020 adds a second pattern, a cracked flex plate. Owners also report flex plate cracks in 2019. Federal records show no recalls in this area for any of these years.
Owner complaints filed with NHTSA under engine, engine and engine cooling. Newer model years have had less time to collect complaints.
What goes wrong
Most engine complaints on this car describe the same failure. Coolant gets into the cylinders, and the level in the reservoir drops with no puddle under the car. Owners then see a check engine light, a misfire on one cylinder, rough running and white smoke from the exhaust. Many cars get new spark plugs and coils first, and the misfire returns. Owners name both the 1.5L and 2.0L EcoBoost engines.
The risk is real. Some cars lose power or stall at highway speed, and one owner describes crossing four lanes of traffic with a smoking, powerless car. Others were told not to drive the car at all, and several sit unrepaired after diagnosis. The data shows no crash, fire or injury reports in this area for 2018 through 2020, but a stall in traffic is a safety problem on its own. Engine problems make up 398 of the model's 975 owner complaints.
Symptoms owners report
Coolant loss with no visible leak
The reservoir keeps dropping and some owners top it off every other day, yet nothing drips under the car. One owner's heater stopped working. Others heard coolant gurgling when the heat was on. This is often the earliest sign.
Misfire and rough running
A check engine light, often flashing, points to a misfire on one cylinder. Cars shudder, idle roughly or start hard when cold. Owners say new spark plugs and coils bring only a short break before the light returns.
White smoke and overheating warnings
White exhaust smoke at startup is common. Some cars also show an engine overheating or coolant over-temperature message, a temperature gauge that swings, or smoke from the engine bay.
Power loss or stalling while driving
Several owners lost power at highway speed and had to coast to the shoulder. Some cars drop into reduced-power limp mode. Others stall at a stop. A few were towed after a shop found zero compression in two cylinders.
Cracked flex plate rattle
Seen mostly in 2020 and 2019 complaints. Owners hear rattling, knocking or loud clicking and shaking at idle, often louder with the air conditioning on. Usually no warning light comes on first. One owner describes the part as broken in pieces.
Cracked block or seized engine
Some shops find a cracked engine block or a cracked cylinder wall. One owner's engine seized at 100,000 miles. In these cases the car is usually undrivable and the shop recommends a replacement engine.
When the problems start
Across the three model years, most failures land between about 60,000 and 132,000 miles. Some come far earlier, with one report near 32,000 miles. A cracked flex plate shows up at 69,400 miles in one 2019 complaint. Low mileage does not rule out a failure, and another owner reports coolant loss and white smoke at about 126,000 miles.
Repairs and recalls
Owners say dealers usually recommend a long block or full engine replacement. Quotes in the complaints include $7,200, almost $8,000, almost $9,000, $9,742 and 10k. Flex plate repairs are quoted at nearly $2,000 to $3,000. Many owners say Ford declined to help with the cost, or offered only partial help. One owner with a low-mileage car had the engine replaced under a warranty extension. Owners mention Ford service bulletins and customer programs, but federal recall records list no recalls in this area.
Checking a used Fusion for engine problems
- Ask for service records that show coolant top-offs, misfire repairs or an engine replacement, and who paid for them.
- Check the coolant reservoir cold, then recheck after a test drive. A falling level with no leak is a warning sign.
- Start the engine cold and watch for white smoke, shuddering or a rough idle in the first minute.
- Have a shop scan for stored misfire codes and past check engine events, even if the light is off.
- Listen at idle with the air conditioning on for rattling or knocking that could mean a cracked flex plate.
- Ask the seller whether any warranty or Ford coverage still applies to the engine, and get it in writing.
A VIN check shows whether the car you're looking at had its recall work done, plus accident and title history.
Ford Fusion Engine Problems: common questions
- Which Ford Fusion years have the most engine complaints?
- The 2018 model year has the most engine complaints, and 2019 is close behind. The 2020 model year has far fewer, but newer cars have had less time to collect complaints. All three years show the same coolant-in-cylinder failure, so none should be treated as a safe pick.
- Is it safe to drive a Fusion with coolant in the cylinders?
- Owners say no. Some dealers told them not to drive the car. Cars have lost power at highway speed, stalled, overheated and seized. The data shows no crash, fire or injury reports for 2018 through 2020, but a stall in traffic is dangerous.
- Is there a recall for Ford Fusion engine problems?
- Federal recall records list no recalls in this area. Many owners complain about that. Some cite Ford service bulletins or customer programs, but those are owner statements. Check the VIN with Ford or a dealer before you buy or pay for a repair.
- How much does a Ford Fusion engine repair cost?
- Owners report engine replacement quotes from $7,200 to about $10,000, with $9,742 among them. A cracked flex plate is quoted at nearly $2,000 to $3,000. Many owners say Ford declined to share the cost, so ask about coverage before you agree to work.
- What are the first signs of Fusion engine failure?
- The earliest signs are coolant that drops with no leak, a check engine light for a one-cylinder misfire, a harsh cold start and white exhaust smoke. Some cars give no warning light first, especially with a cracked flex plate, which shows up as rattling at idle.
