| Recurring |
one_organization |
(a) The software failure incident related to the Ford Focus vehicles not receiving the intended software update to the powertrain control module has happened again within the same organization, Ford. This incident led to a second recall for about 58,000 examples of certain Ford Focus vehicles [86973]. The issue was supposed to be remedied in a previous recall but a smaller subset of vehicles did not receive the proper update, leading to the need for a second recall.
(b) There is no information in the provided article about the software failure incident happening again at multiple organizations or with their products and services. |
| Phase (Design/Operation) |
design |
(a) The software failure incident in the Ford Focus recall was related to the design phase. The issue stemmed from the car's canister purge valve malfunctioning, which was part of the fuel system. The powertrain control module responsible for detecting a stuck-open valve may have malfunctioned, leading to potential problems with the fuel tank and fuel gauge. The specific subset of vehicles affected did not receive the intended software update to the powertrain control module, indicating a failure in the system development or update process [86973].
(b) The software failure incident was not directly attributed to the operation phase or misuse of the system in the articles provided. |
| Boundary (Internal/External) |
within_system |
(a) within_system: The software failure incident in this case was within the system. The issue originated from the powertrain control module not receiving the intended software update, leading to potential malfunctions related to the canister purge valve and the fuel system in the recalled Ford Focus vehicles [86973]. |
| Nature (Human/Non-human) |
non-human_actions |
(a) The software failure incident in the Ford Focus recall was due to non-human actions. The issue stemmed from the car's canister purge valve malfunctioning and the powertrain control module not receiving the intended software update, leading to potential problems with the fuel system and fuel gauge [86973]. |
| Dimension (Hardware/Software) |
hardware, software |
(a) The software failure incident in the Ford Focus recall was related to hardware issues. The problem originated from the car's canister purge valve in the fuel system, which might have stuck open. Additionally, the powertrain control module responsible for detecting a stuck-open valve may have malfunctioned. This combination of hardware issues could lead to excessive vacuum deforming the fuel tank, causing fuel gauge malfunctions or vehicle stalling [86973].
(b) The software failure incident in the Ford Focus recall was due to a subset of vehicles not receiving the intended software update to the powertrain control module. This lack of software update was the reason for the second recall issued by Ford to address the issue [86973]. |
| Objective (Malicious/Non-malicious) |
non-malicious |
(a) The articles do not mention any malicious intent related to the software failure incident. The failure was due to a subset of vehicles not receiving the intended software update to the powertrain control module, leading to issues with the canister purge valve and fuel system [86973].
(b) The software failure incident was non-malicious, as it was a result of a technical oversight or error in the software update process rather than any intentional harm to the system. |
| Intent (Poor/Accidental Decisions) |
unknown |
The intent of the software failure incident in the Ford recall was not explicitly mentioned in the provided article. Therefore, it is unknown whether the failure was due to poor decisions or accidental decisions. |
| Capability (Incompetence/Accidental) |
accidental |
(a) The software failure incident in the Ford Focus recall was not explicitly attributed to development incompetence. The article mentions that the vehicles in the new recall did not receive the intended software update to the powertrain control module, but it does not specify the reason behind this oversight [86973].
(b) The software failure incident in the Ford Focus recall seems to be more aligned with an accidental failure. The article states that the problem stemmed from the car's canister purge valve and that the powertrain control module may have malfunctioned in detecting a stuck-open valve, leading to potential issues with the fuel tank and fuel gauge. The fact that a subset of vehicles did not receive the proper software update suggests an accidental oversight rather than intentional incompetence [86973]. |
| Duration |
temporary |
The software failure incident described in the article is more aligned with a temporary failure. The article mentions that a specific subset of vehicles did not receive the intended software update to the powertrain control module, leading to the need for a second recall [86973]. This indicates that the failure was temporary and limited to those vehicles that missed the software update, rather than being a permanent issue affecting all vehicles. |
| Behaviour |
omission, value, other |
(a) crash: The software failure incident in the Ford Focus vehicles was not described as a crash where the system loses state and does not perform any of its intended functions [86973].
(b) omission: The software failure incident in the Ford Focus vehicles can be categorized as an omission, as the specific subset of vehicles did not receive the intended software update to the powertrain control module, leading to the need for a second recall to address this omission [86973].
(c) timing: The software failure incident in the Ford Focus vehicles was not related to timing issues where the system performs its intended functions but at the wrong time [86973].
(d) value: The software failure incident in the Ford Focus vehicles can be categorized as a value issue, as the powertrain control module may have malfunctioned, leading to excessive vacuum that could deform the fuel tank, causing issues with the fuel gauge or stalling the vehicle [86973].
(e) byzantine: The software failure incident in the Ford Focus vehicles was not described as a byzantine failure where the system behaves erroneously with inconsistent responses and interactions [86973].
(f) other: The software failure incident in the Ford Focus vehicles can be categorized as a flaw in the software update process, where a subset of vehicles did not receive the necessary software update, leading to potential fuel system issues [86973]. |
