Top problems in owners’ words

Power train

127 reports3 crashes5 related recalls
“My vehicle was just diagnosed with trouble code P2888 (Park Lock Actuator Circuit/Open). This prevents the vehicle from shifting safely into Park. SHIFT SYS FAILURE was the error displayed in the dash readout. This matches the exact model, year, and dangerous symptoms outlined in Ford Safety Recall 26S48. My local Ford dealership has recommended the exact repair specified by that recall—a full transmission valve body replacement. Despite having the identical component failure and safety risk as the recalled vehicles, I am being asked to pay out of pocket solely due to my VIN assembly date. Because this is a known, documented manufacturing flaw, I respectfully request that Ford provide goodwill coverage to resolve this repair. They denied it despite acknowledging the matching details.”

Engine

“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…”

Electrical system

48 reports4 crashes5 fires1 related recall
“The passenger window and the driver window will not respond. The windows will not go up on either side, exposing the driver and passengers to the elements of rain. In addition, the car is vulnerable to theft and break-ins. The windows are part of a larger electrical problem that the car has, including key fob delays and screen shut off during driving. The problem has been confirmed by the service center. No warning signs are available for these problems.”

Back over prevention

36 reports7 related recalls
“The contact owns a 2021 Ford Explorer. The contact stated that the vehicle was taken to the local dealer to be repaired under NHTSA Campaign Number: 26V123000 (Back Over Prevention). The vehicle failed to connect or communicate with the computer and module. The dealer informed the contact about a possible diagnostic test. The vehicle was not repaired. The manufacturer was contacted and advised the contact the manufacturer was not responsible to cover the diagnostic test. The failure mileage was unknown.”

Visibility/wiper

28 reports
“They have fixed zero recalls. I have no wipers at all. I’ve attempted to get a resolution multiple times with no care or concern nor resolution. This is ridiculous. A recall almost 8 months and people have zero wipers!!! And the engine recall. It’s going to blow up before it’s fixed!”

Structure

25 reports
“The right rear passenger door of my 2021 Ford Explorer ST repeatedly becomes unlatched and physically opens while the vehicle is in motion, including at highway speeds of approximately 72 mph. This occurs almost every time the vehicle is driven and creates a serious safety hazard. The door visibly separates from the vehicle’s body, which I can see in the passenger-side mirror. When this occurs, the dashboard displays a door-ajar warning, the interior lights illuminate, and wind can be heard entering through the opening. This is not simply a faulty warning indicator. The door is physically opening while the vehicle is moving. I am extremely concerned about the risk of the door opening farther and potentially causing a passenger, particularly a child seated in the rear, to be seriously injured or ejected from the vehicle. This defect was present before the vehicle was taken to Tipton Ford in April 2026. I also recall that that when I originally purchased the vehicle, the child safety lock was engaged on the right rear passenger door only. I found this unusual at the time, and given the ongoing malfunction involving that same door, I am concerned the issue may…”
