What 398 owners told NHTSA about the 2021 Ford Explorer Gas

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 NHTSA.

2021 Ford Explorer used a work vehicle (house cleaning business) and family vehicle after hours (driving my daughter to soccer practice 4 times a week). Vehicle has been professionally and properly serviced since we first purchased it in 2021( we have been the only owners). Car has worked great not one single problem other then regular things like tires, brakes and battery all purchased and installed by Ford dealership. The day of the incident the car was working perfectly the entire day. As I drove on the freeway taking my daughter to soccer practice in the evening. I noticed the vehicle started to shake and lose all power the vehicle stopped almost completely in a matter of seconds causing cars behind us to almost crash us from behind it was a miracle no one crashed into us as we were traveling at freeway speed 60-65mph. With the little power the car had I cleared 2 lanes and parked on the side of the freeway. A friend of our picked up my daughter as we were both frightened by the incident. The vehicle gave me no alerts that there was something wrong no warnings on the Ford pass app nothing. I had the vehicle towed to Walnut Creek Ford for inspection. Ford did a diagnostic and found that the engine had a hole from the head to the block. They don’t know how this happened and say they have never seen this before. They said the vehicle is in great shape inside and out and even with 160,000 the car is very well maintained (serviced). This needs to be addressed to Ford as lives were in danger and people could have gotten hurt. They want 13,000 to repair engine, but it seems to everyone(ford technicians and second opinion mechanics) it was an engine factory defect. Vehicle suffered catastrophic engine failure while driving on freeway with no warning from the vehicle system, check engine light never came on nothing. It all happened in a matter of seconds. Engine light only came on after the vehicle was no longer drivable.

I own a 2021 Ford Explorer ST (3.0L EcoBoost) with 47,680 miles. The vehicle is exhibiting a severe metallic knocking noise at idle, a flashing Check Engine Light, and a dangerous loss of motive power while driving. A certified Ford dealership technician (Kendall Ford) diagnosed the vehicle with catastrophic engine failure, requiring a full engine replacement estimated at $13,000.My vehicle is exhibiting the exact mechanical failure described in Recall 24S55 (NHTSA Campaign 24V635000) regarding brittle engine intake valves. Although my vehicle shares the same build year, engine type, and failure symptoms as the recalled units, Ford states my specific VIN is not currently included in the 'repair' population.The sudden loss of engine power while operating at highway speeds creates an immediate crash hazard. I request that the NHTSA investigate whether the scope of Recall 24S55 should be expanded to include this production range.Furthermore, Ford offered a 'goodwill' assistance of approximately $3,762, which I believe is an admission of a known manufacturing defect. At the time of this failure, the vehicle was only 17 days past the 5-year warranty period and well under the 60,000-mile limit. Despite this premature failure and the safety risk, Ford refuses to cover the full replacement, leaving me with a $9,000+ bill for a defect already acknowledged in 90,000 other units.

The vehicle has an ongoing oil leak originating from the engine/drivetrain area. The affected components include the intermediate shaft and related seals, which are subject to Ford technical service bulletins, and potentially the plastic engine oil pan and its sealing surfaces. The vehicle is currently operable and remains available for inspection upon request. he vehicle is actively leaking engine oil at approximately one drop per day. Oil leakage presents a safety risk due to the potential for oil contacting hot engine or exhaust components, reduced lubrication if the condition worsens, and the possibility of oil dripping onto road surfaces, which could reduce traction for other motorists. The condition has not caused an accident to date, but it presents an ongoing safety concern. Yes. A Ford dealership identified and documented oil leakage during a scheduled service visit in November. In addition, the dealership acknowledged known issues with the affected components and confirmed that the vehicle continues to exhibit oil leakage. The manufacturer has declined repair outside of warranty. The vehicle has been inspected by an authorized Ford dealership on multiple occasions. Ford Motor Company executive customer care reviewed the case and documented a decision to decline repair based on warranty status. The vehicle has not been inspected by police or insurance representatives. No warning lamps or messages were present prior to the discovery of the oil leak. The condition was first identified visually during a scheduled service visit in November when oil leakage was observed. The vehicle currently exhibits ongoing oil leakage without warning lamps or messages. I am also concerned that this model has had several recalls regarding the engin and our falls just outside the range of Ford recall it was build in January of 21 and the recall starts in May of 21. I would like to have that expanded to my vwhicle as well.

I was informed by the dealership that the engine issue with my 2021 Ford Explorer is the same issue for which a recall was issued. However, because my vehicle’s VIN was not included in the recall, I was required to pay for the engine replacement. I attempted to work with the dealership to have them coordinate with the manufacturer, but they declined to do so. I then contacted the manufacturer directly to file a complaint and request a review of the issue. I was advised that there was nothing they could do because my VIN is not listed under the recall. I am requesting that the manufacturer investigate this matter further and reimburse me for the repair costs if it is determined that the issue is applicable to my vehicle.

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.

My explorer is only 4 years old and it suddenly suffered catastrophic engine failure due to low engine oil. The engine started knokcing and clattering BEFORE any warning lights came on the dash. This could also be due to premature bearing failure which is common in the 3.0 ecboost engines.

My vehicle is experiencing exhaust fume issue where the exhaust fumes are entering into the cabin for Explorer and Aviator models (Any model with the 3.0L Ecoobost). Upon inspection by 3rd party mechanic, it can be determined that the problematic catalytic converters that are not the one piece cast was installed on my vehicle from the factory. Speaking to other ST and Interceptor owners, the problem seems widespread to every 2021 model that Ford installed the multipiece welded catalytic converters. Apparently the cast part fairs better and is not subject to cracks. The recall originally covered the left side catalytic converter but the flawed design also affects the right side catalytic converter where many owners are experiencing this issue. This has affected all 3.0L Ecoboost engine vehicles. [XXX] I believe the recall should have extended to cover all 2020 and 2021 model year vehicles. There are forum posts where owners outside the recall have experienced the issue in addition to owners having to repeatedly replace the catalytic converters post warrant as Ford continued to reinstall bad catalytic converters as part of the repair process. I have driven this vehicle for several thousand miles with the issue and did not realize exhaust was leaking until notices of headaches and health issues as CO is odorless, causing CO2 levels to reach 3000+ inside the cabin at stop lights and blows in through the vents if A/C is on. I believe NHTSA should investigate this issue further and require Ford to replace both catalytic converters as this issue poses a serious health hazard, especially given the location of the exhaust leak and the commonplace occurrence. I am happy to forward to forums and provide evidence of this occurring. Ford considers lifetime of the vehicle to be ~150K miles and these exhausts do not last close to that, resulting in a massive expense and danger to US consumers.

While our 2021 Ford Explorer with 47,000 miles to work the vehicle warning light came on stating the vehicle was overheated and shut down. We allowed the vehicle to cool for 20 minutes as recommended by the owners manual and then restarted the vehicle which immediately overheated again. We had the vehicle towed to the local dealer who diagnosed the issue as coolant in the oil forcing a replacement of the engine and coolant systems.

We were driving the vehicle when we experienced a sudden loss of power and acceleration. We also noticed odors of gas. We took it to a Ford authorized dealership and they said it was due to antifreeze in the oil from what they said was a leaking water pump. They recommended a new engine due to the difficulty of changing the internal water pump and the fact it leaked antifreeze into the engine oil, possibly damaging the engine itself. This was the explanation for the fault codes, random gas odors, and loss of power. It was explained this was normal when the sensors detect something wrong with the oil in the engine. Estimated cost provided by the dealership was $11,000 to replace the engine.

[XXX] after driving less than 10 min. warning signs flashed on screen. I immediately pulled off the road where the vehicle completely shut down and realized my 2021 Ford Explorer was on fire. Bystanders attempted to put the fire out with fire extinguishers but were unsuccessful. My passenger and I opened our doors, I exited and attempted to open trunk to remove wheelchair but could not (because door is electrical). My passenger flung himself onto the ground until bystanders came with a rolling office chair to remove him away from the burning vehicle. Had the bystanders not been there I do not know how I would have been able to move my passenger (25 year old, 200 lb male) away from the burning vehicle. Fire Marshall could not determine cause of fire because vehicle was completely melted/too damaged. Ford Motor Company reviewed photos I sent to them but claims they could not determine cause of fire. The vehicle was properly maintained with routine oil changes. There were no issues with the vehicle prior to this incident.
