Ford Ecosport misfire problems

Filed Nov 1, 2026 · Engine · AZ

On August 20, 2026, my 2018 Ford EcoSport equipped with the 1.0L EcoBoost engine suddenly shut down while I was driving on the highway. The unexpected loss of engine power created a serious safety concern because the vehicle became disabled while traveling in highway traffic. This failure occurred despite extensive previous engine-related repairs, including completion of Ford Safety Recall 23S64. On September 15, 2025, the vehicle overheated, the check-engine light illuminated, and coolant had to be added. Camelback Ford subsequently diagnosed a cracked thermostat housing, cracked coolant expansion reservoir, and failed reservoir cap. These components were replaced. During the same September 2025 service visit, Camelback Ford performed Safety Recall 23S64, replacing the engine oil-pump drive belt, tensioner, and timing belt on the original engine. In December 2025, the vehicle experienced significant power loss. Camelback Ford diagnosed a failed vacuum pump and discovered that the turbocharger’s internal turbine had come apart and completely seized. The turbocharger was replaced in January 2026. Approximately seven months later, on August 20, 2026, the engine unexpectedly shut down on the highway. The vehicle was taken to Earnhardt Ford. On October 16, 2026, the dealership reported severe coolant intrusion into cylinder 3. During a cooling-system pressure test, cylinder 3 filled with coolant within approximately 10 minutes. Diagnostic codes included P0217, P0301, P0303, P0316, P1285, and P1299, indicating overheating and engine misfires. Earnhardt Ford suspects an internal cylinder-wall failure but has not confirmed the exact source of the coolant intrusion. The dealership recommends complete engine long-block replacement. I am concerned about the safety of these engines, particularly the risk of sudden engine shutdown while driving, even after completion of an engine-related safety recall. I request that the federal safety agency review this incident for a potential safety def

What component or system failed or malfunctioned, and is it available for inspection upon request? The braking system failed, preventing the vehicle from stopping properly. The vehicle is currently at a tow yard and is available for inspection upon request. How was your safety or the safety of others put at risk? Because the brakes failed, I was unable to stop at a traffic light. The vehicle entered oncoming traffic and was involved in a collision, placing my safety and the safety of other motorists at risk. Has the problem been reproduced or confirmed by a dealer or independent service center? No. I previously took the vehicle to the dealership several times for misfire and powertrain-related issues. The dealership was unable to identify the underlying problem and advised that the spark plugs were not tightened properly. Similar issues have occurred multiple times over the past few years. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle is currently at a tow yard and is awaiting inspection by the insurance company. Additional inspections may be conducted as part of the claim investigation. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes. Warning lights appeared earlier this week, and I brought the vehicle to the dealership for diagnosis. The dealership was unable to determine the cause of the warnings.

After fueling, codes P0496 will show and car will not start or struggle to start. Stalling when on freeway and rough idle. My vehicle shut off on the freeway causing me to almost crash and had to stop immediatly. In my investigation, it seems I am not the only one suffering this issue. I am on my 2nd engine replacement from the original recall as well.

My 2018 Ford EcoSport is subject to Safety Recall 23S64, concerning a defective oil pump belt and/or tensioner that can lead to engine failure. My VIN is listed in this recall. The engine has symptoms consistent with this recall, including performance loss, mechanical noise, and diagnostic codes such as P0014 (camshaft timing over-advanced), P0303 (cylinder misfire), and U0100 (lost communication with ECM/PCM). The vehicle is currently located at an authorized Ford dealership (Sunrise Ford of North Hollywood). However, the dealer has refused to perform the required diagnostic inspection unless I pay $1,084. This is a direct violation of federal law under 49 U.S.C. § 30120, which mandates that both diagnosis and remedy of safety-related recalls must be provided free of charge. I have also documented communication from the dealership and a written inspection from an independent licensed repair shop showing the engine is in as-found condition and that no repairs were attempted. I am seeking enforcement action to ensure that the recall is honored as required by law. Dealership: Sunrise Ford of North Hollywood Address: 5500 Lankershim Blvd, North Hollywood, CA 91601 Service Advisor Name: Bruno Rivero

We noticed rattling and misfiring sounds from the motor but no warning indications on the dash. 2 days later when my wife was coming home the car started losing power and "died". Would not restart but no warning lights on dash. The app did send a notice about loss of pressure to turbo. Had my wife not been near someplace to pull into she would have been stranded in the road in a disabled vehicle. Traffic was backed up behind her while she was trying to get out of the road. Had the car "died" while she was on the interstate doing 70 it would have been COMPLETELY without power steering AND brakes. The car has ONLY been serviced by our local Ford dealer. So we had it towed there. This morning they are telling us it's a problem with the "integrated exhaust manifold" that allowed water into the cylinders and ruined the engine. Believe they called that a cracked block years ago? Something that shouldn't happen to a car with only 66K miles. They assured us it wasn't the oil pump from the recall. We just paid it off a couple months ago. Now it needs a new $6,300 motor. Not something senior citizens only a year from retirement can easily swing. There NEVER was ANY indication (warning lights, etc) or warning from the dealer after service of any problems. It seems that Ford has more problems with this motor than just the oil pump!!

Purchased the 2021 Ford EcoSport from Courtesy Ford (new), where I have the regularly serviced the vehicle. However, my ownership experience has been marked by repeated mechanical failures that have escalated to the point where, after only three years of ownership, I am being asked to replace the transmission—a repair I believe is both premature and unjustified given the circumstances outlined below. Timeline of Issues and Repairs: July 17, 2023: First experienced significant engine performance problems, particularly with the Auto Start feature malfunctioning, which led to the engine stalling while driving. Despite multiple tests, these issues persisted. Eventually, the engine was replaced, but I continued to experience jerking and misfiring after the replacement. October 2023 – January 2024: Despite having the engine replaced, the car began showing worsening jerking and misfiring, especially at higher speeds (60-65 mph or above). February 2024: During routine maintenance, I was informed that a catalytic converter needed replacement due to damage caused by the engine misfiring. I also learned that the starter motors were not replaced during the engine swap, despite it being common to get a tune up at about 80,000 and expecting thorough work after a engine replacement (Is that too much to ask) also being that I get ALL repairs and maintenance done here just for the service “ADVISOR’ to tell me you were been supposed to get a tune up, hysterical October 2024 – January 2025: The engine started losing power and struggling to rev, similar to before the new engine and catalytic converter replacement. After two weeks, I received a $3500 estimate for starters, coils, plugs, a coolant flush, and code P0128. After waiting for recall plans and assistance, I was informed that the technicians had added the two coils and plugs they initially had on the $3500 estimate and said after test driving it w/ those, they see that a new transmission is needed for $7500.
