Filed Oct 10, 2026 · Engine · MI

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)

While driving the vehicle, in any mode, the car will stutter or "cough" causing it to slow down. I have to pull the vehicle to the slow lane until it eventually corrects itself. Also, on multiple occasions when I hit the gas the car stalls until I let off the gas pedal and let the car "think" for a moment and then it will drive. This happens a lot at stop signs or when the light changes. I will hit the gas to go and the car does nothing. It feels like the engine stalls even though the car is still on. On a few occasions I will be driving at high speeds on the interstate and I will punch the gas to go around a car and it stalls. On EVERY occasion when this happens, whether I am pulling out at a busy intersection or am driving with the flow of traffic on the interstate, I am around multiple cars and cars are having to hit their brakes or swerve to avoid my vehicle. When this happens it only takes about 10 seconds for the car to go again but that is still long enough to get hit. I am scared to drive my car with my children in it because of this. A have contacted the dealership but they say to bring it in when it is acting up but it does not do it everyday so there is no way for me to do that. They also said they could keep it and drive it but they do no offer a loaner vehicle so I cannot be without my only vehicle for multiple days at a time. On other occasions the vehicle seems like it looses momentum and is very sluggish. Sometimes the car jerks into gear instead of a smooth transition.

While driving with the cruise on at 74 mph the vehicle jerked as if the brakes had been tapped. I shut off the cruise and tried to accelerate but nothing happened. At this point I signaled to change lanes and pulled to the right shoulder. There were no dash lights or warning alarms prior to the engine stalling. Clearly an engine stalling at this rate of speed could have ended bad for all 5 passengers and surrounding vehicles. Vehicle is being towed to Augusta, KS Ford dealer this morning 9/21/26. Vehicle was scanned and is showing a hard code for low pressure to fuel pump. This vehicle is not currently included in the NHSTA Campaign 25V455000.

There was no accident, but very close a few times.when I am stopped at a stop sign or light when I press down on the gas pedal the car hesitates I have to pump the pedal to get the car moving or it would stall in traffic. No check engine light is or has been on. I’ve been to 2 different ford dealerships and after there inspection they claim nothing wrong with my car. It’s already cost me a lot if money. When driving I can feel the car surge likes it’s not getting fuel sufficiently real bad at traveling at or below 50 mph. I’m afraid it will stall and get us t- boned but the mechanics say nothing wrong I disagree there is something wrong. I know another person who had the same problem and he got rid of the car, I can’t afford to do that, please do something to get a recall or something before we’re seriously injured or worse.this started about a year ago and getting worse.

While driving at highway speeds, the vehicle experienced a sudden and total loss of engine power and stalled in active traffic. I lost motive power and had to safely coast through traffic to the shoulder. The vehicle would not restart and had to be towed to a repair facility. The failure matches the exact symptoms of Ford Recall 25S75 / the federal safety agency Campaign 25V455000 for low-pressure fuel pump failure, but my VIN is currently excluded from the recall.

While driving at highway speeds, the vehicle displays a "Drive Train Malfunction" warning message and the traction control warning light illuminates. Shortly after the warning appears, the vehicle loses power and may enter a reduced-power mode or stall, creating a serious safety hazard in traffic. This has occurred while traveling on the highway, forcing sudden deceleration and creating the risk of being struck by other vehicles. The check engine light is illuminated, and diagnostic code P0A1E is present. The problem is intermittent and unpredictable, making it difficult to determine when the next failure will occur. The vehicle has been taken to Ford for diagnosis multiple times, and significant money has been spent attempting to repair the issue. Despite these efforts, the root cause has not been identified and the problem continues to occur. This defect affects the drivetrain system and impacts the safe operation of the vehicle. The sudden loss of power on the highway places the driver, passengers, and surrounding motorists at risk. Based on discussions with other owners, this appears to be a common issue affecting Ford Explorer Police Interceptor Utility vehicles and warrants investigation by the federal safety agency.

Police car started to run rough at low speed. Stalled in middle of road. Scanned codes and code for Catalytic converter showed up along with misfires from numerous cylinders. Brought to dealer and was told needed plugs and a wire. Vehicle was returned and the same issue occurred. Fixed again. Picked up and once again the same issue started. Turned around and brought it back to dealer. The mechanic stated he never checked the catalytic converter as he was never told it had a code for the converter being bad. Two weeks later I am informed that Cylinder 5 is bad. No compression. Two issues. Ford upped the warranty on the catalytic converters because of this common problem. The tech sheet shows that a bad cat will cause misfires, but never checked. Second issue is the recall 24s55 was for fords with a 3.o liter engine, built in Chicago, between the dates of 7/21 and 10/21. My vehicle was built in Chicago on 9/21 and has a 3.0 liter engine. I also received the post card regarding the recall and we had brought it t o the dealer. 24s55 states the valve could cause engine failure. Well now I have a bad engine. Ford says no recall even though prior Chief brought to dealer after receiving postcard for recall.
