Ford Explorer misfire problems

Filed Oct 24, 2026 · Transmission · CO

About 3 years and 3 months after a Power Control Module reflash was done in March 2021 under the Customer Satisfaction Program (CSP) 20B27, vehicle was brought to Ford dealership on 06/07/2024 with mileage at 79,730 for multi point inspection due to vehicle runs rough and hard time accelerating. Diagnostic code was P0316. Service tech recommendation was to replace engine for $14,000.00 including parts and labor (declined recommendation). Brought vehicle to another dealership but found no codes. Instead replaced engine motor mounts, sparkplugs, and air filter due to noticeable vibrations. Dealership service tech inspected engine but found no abnormal findings. Went to another Ford dealership on 10/08/2026 to check Code P0299 that appeared on OBD test and for further inspection due to sluggish acceleration from full stop and slows down going uphill. Ford's guidance stated that torque converter failing due to mileage, acceleration/power loss from dead stop. Recommended fix was to replace the transmission for $8,461.03 (declined recommended service). On 10/23/2026, I picked up my vehicle from the dealership. During my return journey from the dealership, I encountered the same sluggish acceleration. A safety hazard that is attributed to a malfunctioning torque converter, a know problem for Ford. Consequently, Ford dispatched CSP 20B27 to assist in safeguarding the transmission converter from overheating. Regrettably, this intervention proved ineffective in mitigating the problem. Ford issued CSP 20N07 to extend warranty coverage of the automatic transmission torque converter for 12 months from RO date which in my case, RO date on CSP 20B27 was 03/19/2021. Despite the 12-month eligibility period not being met, my vehicle should have remained covered. Initially, Ford was aware of a transmission torque issue and was attempting to resolve it through CSP 20B27 and CSP 20N07. Currently, mileage is at 85K miles but I'm hesitant to drive due to safety concerns.

Vehicle: 2021 Ford Explorer XLT - 2.3L EcoBoost I-4 VIN: [XXX] Odometer: 127,824 Date of failure: [XXX] Complaint Description: I am reporting a complete engine failure due to coolant intrusion on my 2021 Ford Explorer 2.3L EcoBoost. This is the known defect affecting 2016-2024 Explorer 2.3L engines. Independent shop diagnosis from attached receipt states: "Engine failure due to Head problem, which cylinder 3 + 4 and head in engine known for coolant intrusion. Cylinder Head failure, carbon build up plus Turbocharger also failure." Vehicle stored DTCs P0300, P0302, P0304, P0316 - random misfire and start-up misfire. Symptoms included rough idle on cold start, white smoke from exhaust, loss of power, check engine light. Mechanic confirmed coolant in cylinders 3 and 4 due to cylinder head failure. This matches Ford's own TSB process for coolant intrusion where if coolant is found, the long block must be replaced. Safety Risk: Loss of drive power, stalling, overheating. This occurred at 127k miles with regular maintenance. This is not wear and tear - this is the documented design defect where machining grooves in the head allow coolant to pool and leak into cylinders. I have requested Ford Customer Relationship Center (1‑866‑436‑7332) open a case for goodwill and check VIN for open recalls including 23S05 (PCM/10R60) and the June 2026 2.3L long block recall for roller finger failure. Ford has not yet issued a formal recall for coolant intrusion despite class action litigation. Request: the federal safety agency investigate and expand recall to include 2021 Explorer 2.3L EcoBoost coolant intrusion / cylinder head failures. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

At approximately 17,000 miles the Explorer started misfiring, would not shift out of gear and check engine light would flash. Dealer replaced #1 spark plug. 1 week later the car misfiring occurred again, where #4 spark plug was replaced. 18,300 miles later, #1 and #3 spark plugs were replaced due to cracked spark plugs which caused misfire. All instances happened under engine load while merging onto freeway which caused a hazard due to lack of acceleration and reduced speed while getting onto freeway.

On approximately 09/02, I took my 2016 Ford Explorer to an authorized Ford dealership for recall-related PCM service. After the recall service was completed, I experienced additional problems with the vehicle and returned on 09/4 and I also called the same dealership that same day because I believed something was wrong following the repair. The dealership replaced the battery but did not perform additional diagnostics unless I paid out of pocket. I was unable to immediately afford those diagnostic charges, so I later sought additional diagnosis. The vehicle continued to experience drivability/electrical problems, including misfire symptoms and eventually a no-start condition. After further testing, another authorized Ford dealership diagnosed the PCM as faulty. I contacted Ford Motor Company because I am concerned that the recall service, programming, or work performed during the recall may have contributed to the PCM failure. Ford closed my case because the recall was marked completed and stated that my vehicle is outside its warranty period. I returned the vehicle two days after servicing dealership as the recall repair to report problems. I am requesting that this be reviewed as a possible recall-repair-related safety issue. The PCM failure and associated engine/electrical problems could affect drivability and the vehicle’s ability to operate safely. The vehicle and related repair records are available for inspection.

The check engine light was on. A Ford dealership diagnosed the issue as a coolant intrusion manufacturer defect. There are a number of safety concerns associated with this issue. The primary danger of the coolant intrusion defect is catastrophic engine failure. Severe overheating, internal damage, misfires, fire hazard and oil contamination. There are no active recalls\campaigns\TSB for 2022 Ford Explorer XLT 2.3L EcoBoost engine. The car is available for inspection. Although, the vehicle has not been inspected by the manufacturer, police or insurance agent, the issue was presented to Ford and a claim was submitted to the insurance company that services my Mechanical Breakdown Insurance. So far the insurance company is not authorizing the work without an engine breakdown. They are not excepting the P0300 and P0316 code or the results of a barascope and other test. The Ford corporation will not provide a written statement that confirms the dealerships diagnosis is accurate. Some doctrine that states the engine long block had to be replaced to fix the coolant intrusion defect. Ford has recalled coolant intrusion issues on other engine models. I requested a formal Tiered Goodwill Review based on the Miller v. Ford framework and resolution terms. Since the service center’s portal does not display an automatic, VIN-specific internal factory code for a long block replacement. The request was denied. While the Miller v. Ford litigation established corporate accountability for structural block and cylinder coolant intrusion faults in 2.0L blocks, my 2022 2.3L engine shares a highly similar open-deck block geometry and suffers from the exact same systemic coolant failure. Furthermore, Ford has acknowledged manufacturing line coolant and block defects on 2021–2023 2.3L engines through Customer Satisfaction Programs 23B42 and 23B08. Yet there are no recalls associated with my VIN.

I am reporting recurring engine misfires involving my 2025 Ford Explorer Platinum equipped with the 2.3L EcoBoost engine. The vehicle currently has approximately 15,700 miles. The first incident occurred approximately five months ago. The check-engine warning appeared and the vehicle was diagnosed by an authorized Ford dealership with DTC P0303, indicating a cylinder 3 misfire. The cylinder 3 spark plug was replaced. A second misfire subsequently occurred at approximately 15,700 miles. The vehicle again exhibited an engine misfire/check-engine warning and was transported through Ford Roadside Assistance for service. An authorized Ford dealership diagnosed DTC P0301, indicating a cylinder 1 misfire. I was advised that the cylinder 1 spark plug was physically damaged and that a portion/cap of the plug had broken off and was not present. I am concerned because this represents two spark-plug-related misfires involving two different cylinders of the same engine within approximately five months and at relatively low mileage. Ford has issued technical service information addressing P0301-P0304 misfires on certain 2025 Explorer vehicles equipped with the 2.3L EcoBoost engine. I am not claiming that this establishes the cause of my vehicle's failures; I am reporting the recurring condition so the federal safety agency can document it and evaluate it alongside any similar reports. Both incidents were diagnosed by authorized Ford dealerships. Repair documentation and manufacturer/dealership correspondence concerning the incidents have been retained and can be provided if requested. The vehicle/component may be available for further inspection if requested, subject to its current repair status.

Driving down the highway and checkengine light came on when I was headed to work. The vehicle lost power due to misfire with engine. I check the spark plugs and there is oil all over sparkplugs and the coil packs. This is a serious issue and needs to be addressed by ford immediately, they need to put a new engine in or pay me to get this fixed.

My 2016 ford explorers torque converter has failed. It causes a extremely rough idle while in drive or reverse, the rpms vary and at a complete stop the car will continue to lunge forward. If I were to continue to drive the vehicle at any point without warning my transmission could completely lock up causing me to stall in the middle of the road. The dealership has confirmed it as well as ford and ford has an active recall for my specific car but my vin isn't covered under the recall and ford is refusing any sort of fault.
