When I was driving on the highway, the car braked really hard like brake checked. It seemed like it was part of the safety system because a light was flashing on the dash like I was gonna hit something but no car was there. Now my car keeps jolting and breaking fast even when I accelerate it will brake for half a second when I am driving. in my car keeps overheating. The mechanics tell me it’s related to something pinching off oil lines and the transmission possibly and that the recalls are possibly related to this issues. it’s not safe and it’s messing up my transmission and my car keeps stopping and starting in the middle of traffic. I have a family I LOVE my vehicle but it’s not safe and I can’t afford to fix it.

On October 21, 2026, after an approximately one-hour round trip in our 2021 Ford Explorer, we arrived home and noticed smoke coming from under the hood. When we opened the hood, we found oil spread throughout the engine compartment. The smoke and oil leak raised concerns about a possible fire and the safety of continuing to drive the vehicle. The vehicle had recently received its second replacement engine, installed by Stuckey Ford of Bellefonte on September 2, 2026. We brought it back to that dealership on October 23. Service staff told us they believed the oil leak involved the valve cover gasket on the recently installed long block. This is a preliminary diagnosis; we have not received written confirmation of the cause. As of October 26, the vehicle remains at the dealership awaiting repair and is available there for inspection upon arrangement. Whether Ford has independently inspected this new issue is unknown. The vehicle has a history of repeated oil loss and low oil pressure warnings. The original engine was replaced under warranty in June 2024 at approximately 39,574 miles after the dealership documented oil in cylinder 2 and heavy cylinder wall scoring. In June 2026, we again reported almost no oil and a low oil warning. In July 2026, at 77,206 miles, the dealership documented excessive oil consumption and internal oil burning in cylinder 3, leading to the September replacement. Shortly after that replacement, the vehicle also displayed an overheating warning and required towing. The dealership found that a coolant hose had come off and repaired it in September. Whether warning lights or messages appeared before the October 21 oil leak and smoke incident is unknown. The repeated engine problems and this new incident have left us concerned about safely using the vehicle.

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.

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.

The internal timing-chain-driven water pump on my 2019 Ford Explorer Sport 3.5L EcoBoost is failing. I began experiencing coolant loss and the cabin heat would turn cold while the vehicle was stopped or idling. The vehicle was professionally inspected by an independent repair facility. After diagnostic testing, the mechanic confirmed coolant leaking from the water pump weep hole and diagnosed a failing internal water pump. The water pump is located inside the engine and is driven by the timing chain. Continued failure can result in significant coolant loss, overheating, coolant entering the engine oil, and potentially severe engine damage or engine failure while driving. I am concerned about the safety risk of an unexpected loss of engine operation. The vehicle did not initially display an overheating warning despite the coolant loss and heating symptoms. The failure has been confirmed by a professional mechanic and documentation/photos of the leak and diagnosis are available upon request. Replacement requires extensive engine/timing-system disassembly and I was quoted several thousand dollars for the repair. I am requesting that the federal safety agency investigate internal water pump failures involving the 3.5L engine used in these Ford Explorer vehicles.

RECALL COMPLIANCE & SAFETY DEFECT DESCRIPTION: The vehicle was transported via roadside assistance to a licensed manufacturer dealership due to severe engine overheating under an active manufacturer safety recall. Service personnel systematically modified intake paperwork to alter the true mechanical state upon arrival, removing safety recall and towing documentation. Intake files were falsified with the notation stating that the customer reported a bad battery, executed solely to evade mandatory factory safety recall tracking protocols and obscure dealer liability for subsequent failures. UNAUTHORIZED SHOP-FLOOR HAZARDS & MECHANICAL DAMAGE: Following custody transfer, shop technicians induced severe physical damage to the vehicle's twin-turbocharger assembly, resulting in a snapped turbo stud and a torn engine air filter. The vehicle was subsequently operated on public roads by shop personnel for 75 to 80 unauthorized miles under active engine overheating conditions without correcting thermal or safety recall failures, creating an immediate risk of catastrophic engine block structural cracking. The safety failures triggered 13 critical system fault codes across powertrain, electrical, and battery systems, which went entirely unaddressed while the shop attempted to compel payment under an altered repair estimate. CYBER SABOTAGE OF OUTBOUND SAFETY TELEMATICS: To actively obstruct diagnostic tracking and safety verification, shop staff executed a forced remote network reset of the vehicle's cellular modem. This reset deliberately severed user profile access and entirely deactivated the outbound telematics pipeline to systematically block the outbound transmission of the 13 powertrain and thermal fault messages to the user and manufacturer databases.

I drove to work with no issues, lights or warnings. I parked and worked for 7 hours. Upon leaving and cranking the engine, it immediately showed overheated and went into limp mode. I drove it less than 100Ft, parked and called for a tow. There was no puddles or other indications of an issue. Upon towing to the closest dealership, I was informed the oil cooler failed putting coolant into the oil and "scorching" the engine and I need an entire new engine. The dealership confirmed there wouldn't be any warning lights of this happening.

While driving at highway speed on a 2-lane highway with three children under the age of [XXX] in the vehicle, my 2018 Ford Explorer experienced sudden complete engine failure with no prior warning. No warning lights, no temperature gauge change, no unusual sounds. The vehicle went from operating normally to catastrophic failure instantaneously, forcing me to sharply cross active traffic to exit the roadway. The vehicle came to rest near a train track. The root cause was internal water pump failure. Ford's design places the water pump inside the engine, causing coolant to leak internally with no external indicators and no dashboard warning until catastrophic damage has already occurred. Ford did not install a coolant level sensor in the reservoir, and the only coolant warning available is an overheating alert, which never triggered. I had taken every reasonable precaution. Two thousand miles prior, an oil change showed no coolant contamination. One week prior, I physically checked the coolant level and it was within safe range. Ford's design gave me zero opportunity to detect or prevent this failure. This is a known recurring issue. Over 86 engine complaints have been filed with the federal safety agency for this model year alone and Ford has been aware of this defect since at least 2007. Despite class action litigation in both Canada and the United States, Ford has not issued a U.S. recall. Repair costs exceed $9,000. I am requesting the federal safety agency open a formal investigation and compel Ford to issue a U.S. recall.

Vehicle: 2018 Ford Explorer Mileage at Failure: 62,212 miles On [XXX] while driving my 2018 Ford Explorer, the wrench warning light suddenly illuminated on the dashboard. At the same time, the vehicle experienced a significant loss of power and became extremely sluggish in acceleration. When I pressed the accelerator pedal, the vehicle failed to respond normally and did not accelerate as expected. This condition created a serious safety hazard because the vehicle could not maintain or increase speed when needed in traffic. Had this occurred while entering a highway, crossing an intersection, or attempting to avoid another vehicle, it could have resulted in a crash. The vehicle has been inspected by McCarthy Ford. The dealership diagnosed transmission-related problems and provided a repair estimate of $6,384.94. Ford Motor Company previously issued Customer Satisfaction Programs 20B27 and 20N07 for certain Ford Explorer vehicles equipped with the 6F35 transmission. Ford's own documentation acknowledges that transmission torque converter overheating may result in low performance, lack of acceleration during launch, sluggish vehicle operation, vibration, shuddering, and related transmission concerns. These symptoms are consistent with the condition experienced in my vehicle. I reported the issue to Ford Motor Company and sent a certified letter to CEO James D. Farley, Jr. requesting assistance and a policy adjustment due to the known transmission and torque converter concerns. To date, I have not received a satisfactory response. I am submitting this complaint because the sudden loss of acceleration and reduced vehicle power created a significant safety risk while operating the vehicle on public roadways.
