Incident

May 27, 2026

The vehicle in question has the coolant intrusion into cylinders 2 and 3 with rough idle on startup, P0300, P0302, P0303, and white smoke on startup. The vehicle now has 111339 miles on it and the out of pocket cost is more than what the vehicle blue books for in excellent condition. TSB 22-2134 speaks to all the issue and what the repair is. If this is a known issue then I feel this should be a vehicle recall by Ford due to the costly repair.

I am the owner of a 2017 Ford Fusion with 61,000 miles on the odometer. Please note that I have always taken good care of my car, having it serviced promptly when required. In recent weeks, I have had to replace my complete steering rack (cost $4,500) and two weeks later, my 1.7-liter Ecoboost engine due to a coolant leak into the number two cylinder at a cost of $6,700. Ford has known about both problems for years and they have resulted in both class action and small claims suits against the company. Regarding the engine, Ford issued Customer Satisfaction Program 21N12, Technical Service Bulletin TSB 22-2134 and Customer Satisfaction Program 19B37 - Supplement #4 to replace the car's engine short block. This covered cars for 7 years of service or 84,000 miles - with, as quoted in the Ford memo sent to dealers on June 9, 2022, "coverage automatically extended to subsequent owners," for presumably the life of the car. Since this is clearly a manufacturing error (as Ford admits in its June 9, 2022 memo to dealers) and not due to negligence on my part, I should be reimbursed for my expenses. The NHTSA should also open a recall case on this matter for owners like myself.

1.5 liter ecoboost engine has a coolant intrusion problem into the cylinder to due a design flaw. Problem can cause several problems: loosing coolant and causing the engine to overheat, causing misfire in the cylinders, and can cause the engine to stallwhich has happened several time on me. The engine should be recalled as a safety concern for stalling, it has stalled on the I15 in Utah several times

Incident

Apr 17, 2026

Coolant light and check engine lights kept coming on. The car was diagnosed by the Ford Dealership as Ford TSB 22-2229, which is a design flaw in specific EcoBoost engines, where an "open deck" block causes coolant to leak into cylinders 2 and 3, leading to severe engine failure. To fix this issue, the TSB requires replacing the entire long block assembly with a redesigned version featuring enhanced sealing surfaces. The cost for this new engine was quoted as $8000 to $9000.

Dec 2022 I purchased a 2017 Ford Fusion. In June 2023 the engine needed replaced which was covered under warranty. In March 2026, the flex plate breaks and now needs to be replaced. This is the original part for this car as I confirmed with the dealer that this part isn't required to be replaced when the engine is replaced. So it's not covered under vehicle warranty or the motor repair warranty. However, there is a known issue of these flex plates breaking and there is Customer Satisfaction Program 22N12 for Ford Fusions regarding this known issue that only covers years 2019 & 2020. I want the 2017 year to be added to this as a known issue.

The contact owns a 2017 Ford Fusion. The contact stated that the vehicle was previously taken to a local dealer, and the transmission was replaced; however, while driving at an undisclosed speed, the vehicle was shaking abnormally while the accelerator pedal was depressed. No warning light was illuminated. The vehicle was taken to another local dealer, where it was diagnosed and it was determined that the engine needed to be replaced. The local dealer provided the contact with a rental vehicle. The vehicle was diagnosed with coolant intrusion in cylinders #2 and #4, DTC: P0316; and associated the failure with Customer Satisfaction Program: 19B37. The vehicle was not repaired due to the cost. The contact associated the failure with TSB 22-2322; however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 119,322.

Incident

Oct 24, 2025

My Ford Fusion has the 1.5L ecoboost engine. This engine has engineering issues that are known to Ford. My vehicle started producing white smoke from the exhaust and sluggish performance. At approximately 105,000 miles my vehicle went into limp mode due to a cracked head gasket. This was due to coolant intruding into the cylinders. Ford did a short block engine replacement and reprogrammed the PCM to try to fix the issue. At approximately 220,000 miles the vehicle started producing the same symptoms described earlier and the vehicle now requires a complete engine replacement. Ford refuses to fix this for me, even though it is well documented that this engine has engineering issues. These engines should last longer than 105,000 miles.
