| Feb 2026 | ENGINE | 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. | Crash: No Fire: No | Unknown |
| Feb 2026 | SUSPENSION,POWER TRAIN | On [XXX], we sent a 2021 Ford Interceptor to J.C. Lewis Ford located at 309 W. Oglethorpe Hwy, Hinesville, Georgia 31313 for a recall under 23S55. The recall is a safety issue related to a rear axle bolt and the possibility the bolt can fracture. We had the recall done and returned the vehicle to service. On or about [XXX], our fleet manager was called to the Liberty County Jail because this vehicle was making a loud noise from the rear end. Our fleet manager had the vehicle towed to the county shop where it was inspected. They concluded the vehicle would need to be towed to Ford for repair since the rear axle bolt fractured, the exact issue that was addressed under the recall. A few days later, we were notified that the dealer was refusing to pay for the repair since they had already done the recall. I contacted Ford Customer Service, case number [XXX], to try and resolve the issue. After going back and forth, I received notification on February 3, 2026, that financial assistance has been denied and that this concern is caused by how the vehicle was / is used over and form of manufacturer defect or previously completed recall. The vehicle is a police interceptor purchased for use as a patrol vehicle for the Liberty County Sheriff's Office located in Hinesville, Georgia. The vehicle is assigned to our civil division and the operator serves evictions and civil documents. The vehicle is not used for patrol but even if it had been, that's the intended purpose of the vehicle when purchased. I have photos of the bolt which show it fractured and also shows the head of the bolt appears to have some damage, possibly from the manner in which it was installed. This failure has been identified as a safety issue related to the 2021 Ford Interceptor and is not a new issue. The recall referenced an axle bolt that can fracture, and that did happen but Ford doesn't want to take responsibility.

The contact's husband, who was an independent mechanic, used a diagnostic machine to diagnose the vehicle and discovered a failure with the emissions system. The contact stated that the failure was like the failure listed in NHTSA Campaign Number: 25V455000 (Fuel System, Gasoline); however, the part to do the recall repair was not yet available. The manufacturer was not made aware of the failure. The failure mileage was approximately 80,000. | Crash: No Fire: No | 80,000 |
| Feb 2026 | UNKNOWN OR OTHER | The drivers side door latch mechanism malfunctions and causes the door to unlatch or does not allow the door to latch. This is a safety hazard. I know two other ford owners with vehicles after 2021 that is having this same issue. This calls for a recall! | Crash: No Fire: No | Unknown |
| Jan 2026 | UNKNOWN OR OTHER | Sun roof fabric/covering came off tracks and is now sagging. Many forums on this issue. When driving if windows are down, the fabric flaps in the wind and sounds like it will fly off. I no longer drive with the windows down. If it continues to sag, could obstruct rear view. | Crash: No Fire: No | Unknown |
| Jan 2026 | ENGINE | 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. | Crash: No Fire: No | Unknown |
| Jan 2026 | EXTERIOR LIGHTING | LED low beam headlight failures. Our 1st headlight failure occurred in January 2025 at 51,248 miles (Passengers Side), our 2nd failure occurred in December 2025 at 64,356 miles (Drivers Side). My claim is Ford decided to embrace LED technology with out properly performance testing it. LED headlights are new on the explorer platform since 2020, the platinum & ST trims are the only ones that utilizes LED's to my knowledge. The design intent was life of car which clearly is not occurring. Ford should have completed more testing and/or designed a serviceable headlight for all internal components. The cost of these lights is astronomical ($1600 a pop w/o labor or diagnosis fee). As reference we also own a 2006 Audi S4 & a 2012 F150 XLT. The Audi has ~170K miles on it and the F150 has ~130k miles on it. Both have the original headlights and bulbs within them. Both older technology and both still working as intended. The headlights in the 2021 car BOTH failed in terms of the low Beam LED components failing in under 4 years. Seems to be a common issue in over 50% of 6th Generation Platinum trim level explores on the market. Numerous others have experience similar issues. Asking for a recall for these. Again only on Platinum & ST trims so not nearly as many at the average XLT level trims. | Crash: No Fire: No | Unknown |
| Jan 2026 | SERVICE BRAKES | While applying brakes coming to a stop light, the vehicle gave a message stating service brakes. The brakes still felt normal. Then after a few minutes, the brakes felt like they suddenly stopped working and then the rear tires started locking up and releasing. The frong brakes felt like they were not working at all. Stopping distance approximately tripled and not really any way to adjust braking pressure. Releasing the pedal would give a 2ish second delay before the brakes would reapply upon hitting the pedal again, and withing 1 second would lock up the rear brakes again, starting the cycle over again. Took approximately 3 applications to fully stop in a safe manner. Luckily I was already driving slow due to the warning and was able stop before hitting the car in front. Was driving approximately 30 mph when this happened. Under normal circumstances and driving distances this would have not been possible. The car was taken to the Ford. They determined there was internal failure in the Electronic Brake Booster. The fix was to replace the full assembly (EBB, ABS, etc), and flush the brake fluid. Along with diagnostics of the issue, the cost was $4,100.87 to fix. Since replacing the EBB assembly, the problem has gone away. There were no other indictions of an issue before this happened. I know other Explorer years, and other models that use this same component have been recalled for similar issues as well, and think there is a issue with this module as well. | Crash: No Fire: No | Unknown |
| Jan 2026 | SUSPENSION | 2024 - 19k miles. Both rear shocks were leaking. Dealer replaced both at no charge. 2025 - 30k rear shock shows signs of leaking. Dealer states no leak. 2025 - 32k Tire shop says shock is leaking. I told them the dealer said it was not. they took pictures. 2025 - Arrive at dealer (2nd time same issue) Dealer states no warranty because I did not pay for replacements. They stated had I payed for replacements I would have a 2 year warranty. Since it's been over a year I have to pay for it. Left dealer called Ford and filed a complaint. Case # XXX-XXX or XXX? Under 40k miles and going on 3 sets of shocks. Online forums readily show this is a known problem that Ford will not acknowledge. Furthermore their warranty of 1 year vs 2 based on payment or warranty replacement should be illegal!

| Jan 2026 | ENGINE | 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. | Crash: No Fire: No | Unknown |
| Jan 2026 | POWER TRAIN | Rear differential/axle bolt broke, destroying other parts and making vehicle unsafe at the moment and then inoperable. Vehicle had previously had the recall work done for this exact issue prior to any issues/damage. Dealership is repairing the vehicle under warranty, but made sure to tell us that this is a known issue and the only true way to “fix” the issue is to install an aftermarket brace (at our cost). | Crash: No Fire: No | Unknown |

| Dec 2025 | UNKNOWN OR OTHER | The sliding roof mechanism for the sunroof failed and droops into the backseat impairing vision. This can be triggered accidentally while driving causing zero rear visibility. This is part of the sun roof that is the shade keeping the sun out of the car. With extremely little use on my 2021 ford explorer this mechanism has failed causing this dangerous malfunction. I found may posts in Facebook describing this same issue. [XXX] There’s just one example of many people having this issue. There’s component was taken to the Ford dealership where I was provided a verbal quote of more than $4,000 to fix, which is not feasible. There were no warning signs.
