NHTSA Recall Query RQ23002 — closed, opened 2023-06-20 and involving the FORD EXPLORER.
NHTSA investigation RQ23002 is a Recall Query opened on 2023-06-20 and currently closed. The subject of record is FORD EXPLORER, which places this file inside the Office of Defects Investigation queue for FORD. Latest activity on this investigation was logged on 2024-02-15 — NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
A Recall Query like RQ23002 evaluates whether a previously issued recall is actually fixing the problem. NHTSA opens an RQ when owners continue to report the original defect after the recall remedy is installed, or when completion rates fall short of the agency's expectations for that risk tier.
Investigators summarized the matter as follows: "On July 17, 2023, the Office of Defect Investigation (ODI) opened this Recall Query (RQ) after receiving 2 consumer complaints alleging loss of vehicle forward power and/or loss of transmission torque of the rear wheels..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related FORD files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
On July 17, 2023, the Office of Defect Investigation (ODI) opened this Recall Query (RQ) after receiving 2 consumer complaints alleging loss of vehicle forward power and/or loss of transmission torque of the rear wheels in model year (MY) 2020-2022 Ford Explorer vehicles (subject vehicles). The RQ was opened to focus on the effectiveness of the remedies of Recalls 22V-255 and 23V-199 related to the alleged problem. Recall 22V-255 involved replacing the bushing and axle cover in the following subject vehicles: 3.3L FHEV Police built before October 14, 2020, and 3.3L Gas Police vehicle built before January 31, 2021. For 2.3L RWD, 3.0L PHEV, 3.3LFHEV, and 3.0LST retail (non-police) vehicles, the recall provided an PCM software update to engage the Electronic Park Brake (EPB) when Park is commanded. The recall addressed a breakage of the rear axle bolt that can cause the driveshaft/half shafts to disconnect, resulting in a loss of transmission torque to the rear wheels necessary to hold park. If the parking brake is not applied, the loss of the primary park torque will allow the vehicle to roll in park increasing the risk of crash and injury. Recall 23V-199 addressed 674 of the subject vehicles produced from February 2, 2019 to April 4, 2022, which received an incorrect remedy under Recall 22V-255. The affected vehicles had received a previous Powertrain Control Module (PCM) update which did not include an automatic EPB engagement when vehicle is shifted to park. On October 17, 2023, Ford filed a new safety recall (Recall 23V-675) covering 238,364 MY 2020-2022 Explorer vehicles with the following powertrains: 3.3L FHEV Police, 3.3L Gas Police, 3.0L Gas Police, 2.3L RWD, 3.0L PHEV, 3.3L FHEV, 3.0L RWD and 3.0L AWD, produced from October 22, 2018 to July 6, 2022, equipped with a 3-point mounted axle design. Ford stated that the cause of the bolt fracture is due to joint design not robust to peak axle input torques and manufacturing variability. The primary contributor is
About This Investigation Type
A Recall Query (RQ) evaluates the effectiveness of a previously issued recall. NHTSA opens an RQ when consumer complaints suggest that a recall remedy may not be adequately addressing the safety issue, or when the recall completion rate appears insufficient.
