NHTSA Recall Query RQ24008 — closed, opened 2024-04-11 and involving the FORD BRONCO SPORT.
NHTSA investigation RQ24008 is a Recall Query opened on 2024-04-11 and currently closed. The subject of record is FORD BRONCO SPORT, which places this file inside the Office of Defects Investigation queue for FORD. Latest activity on this investigation was logged on 2025-10-30 — 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 RQ24008 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 April 11, 2024, NHTSA’s Office of Defects Investigation (“ODI”) opened this Recall Query (“RQ”) to investigate the adequacy of, including various safety concerns associated with, the remedy program in recalls 22V-859..." 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 April 11, 2024, NHTSA’s Office of Defects Investigation (“ODI”) opened this Recall Query (“RQ”) to investigate the adequacy of, including various safety concerns associated with, the remedy program in recalls 22V-859 (filed Nov. 18, 2022) and 24V-187 (filed Mar. 8, 2024). The vehicle population associated with these recalls includes certain MY 2020-2022 Ford Escape vehicles and MY 2021-2023 Ford Bronco Sport vehicles equipped with 1.5L engines. The safety defect in each recall involves high-pressure fuel injectors that are susceptible to cracking, allowing liquid fuel and fuel vapor to migrate onto hot surfaces within the engine compartment potentially resulting in underhood vehicle fires. The remedy programs described in recalls 22V-859 and 24V-187 are identical and involve both a software component and a hardware component. Specifically, Ford developed an updated engine control software designed to detect a pressure drop in the high-pressure fuel rail, provide instrument cluster messaging to the driver, invoke a strategy to disable the high-pressure fuel pump, derate the engine output, and lower the temperatures of possible ignition sources within the engine compartment. Additionally, Ford would install a tube into the engine’s cylinder head drain hole to shunt spilled liquid fuel past the various hot surfaces within the engine compartment and ultimately discard the spilled liquid fuel onto the roadway. ODI identified various safety concerns with this remedy program, which, among other things, notably did not include repairing or replacing the defective part and potentially did include the introduction of new safety defects (like fuel spilling near the spark plugs and fuel spilling onto the public roadway). NHTSA opened this investigation to evaluate these concerns with the remedy program, including whether the vehicles were still susceptible to underhood fires even post-remedy.

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.
