| Recurring |
unknown |
The article does not mention any software failure incident related to the HVAC system issue in the 2019 Ford Ranger being a recurring problem within Ford or at other organizations. Therefore, the information about the software failure incident happening again at one organization or multiple organizations is unknown. |
| Phase (Design/Operation) |
design |
(a) The software failure incident related to the design phase can be inferred from the article. The issue with the 2019 Ford Ranger's HVAC system leading to a possible fire risk was attributed to a lack of enough clearance between the electrical terminal and the conductive-base plate slot. This design flaw increased the risk of an electrical short, which could cause the blower motor to overheat, smoke, and potentially catch fire. This indicates a failure due to contributing factors introduced during the system development or design phase [91123].
(b) The software failure incident related to the operation phase is not explicitly mentioned in the article. |
| Boundary (Internal/External) |
within_system |
(a) within_system: The software failure incident related to the Ford Ranger's HVAC system being recalled for a possible fire risk is primarily within the system. The issue is described as a lack of enough clearance between the electrical terminal and the conductive-base plate slot, leading to an increased risk of an electrical short, blower motor overheating, smoking, and potentially catching fire. This issue originates from within the HVAC system of the Ford Ranger trucks [91123]. |
| Nature (Human/Non-human) |
non-human_actions, human_actions |
(a) The software failure incident related to non-human actions in this case is the potential fire risk in the 2019 Ford Ranger's HVAC system. Ford mentioned that the issue arises from a lack of enough clearance between the electrical terminal and the conductive-base plate slot, leading to an increased risk of an electrical short, overheating of the blower motor, smoking, and potentially catching fire. This issue is a result of a design or manufacturing flaw rather than human actions [91123].
(b) The software failure incident related to human actions in this case involves the recall process initiated by Ford due to the potential fire risk in the HVAC system of the Ranger pickup trucks. Ford is taking proactive steps to address the issue by recalling the affected vehicles, inspecting the blower motor, and replacing it if necessary. This response is a result of human actions taken by Ford to rectify the non-human-induced software failure [91123]. |
| Dimension (Hardware/Software) |
hardware |
(a) The software failure incident in the 2019 Ford Ranger's HVAC system is related to hardware. The issue is described as a possible fire risk due to insufficient clearance between the electrical terminal and the conductive-base plate slot, leading to an increased risk of an electrical short and overheating of the blower motor [91123]. This indicates that the failure originated in the hardware design or components rather than in the software system. |
| Objective (Malicious/Non-malicious) |
non-malicious |
The software failure incident related to the Ford Ranger's HVAC system does not appear to be malicious. The issue is described as a possible fire risk due to insufficient clearance between the electrical terminal and the conductive-base plate slot, leading to an increased risk for an electrical short, overheating, smoking, and potentially catching fire. Ford has initiated a recall to address this non-malicious software failure incident [91123]. |
| Intent (Poor/Accidental Decisions) |
unknown |
The software failure incident related to the Ford Ranger's HVAC system recall does not directly point to a software failure caused by poor decisions or accidental decisions. The issue mentioned in the article is related to a possible fire risk due to insufficient clearance between electrical components, leading to overheating and potential fire hazards. Therefore, the intent of the software failure incident in this case is unknown as it does not specifically mention poor or accidental decisions as contributing factors [91123]. |
| Capability (Incompetence/Accidental) |
accidental |
(a) The software failure incident related to the Ford Ranger's HVAC system recall does not seem to be directly attributed to development incompetence. The issue mentioned in the article is related to a possible fire risk due to insufficient clearance between the electrical terminal and the conductive-base plate slot, leading to an electrical short and overheating of the blower motor [91123].
(b) The software failure incident appears to be accidental, as it is described as a possible fire risk due to a specific physical issue in the HVAC system of the Ford Ranger trucks. The article does not indicate any intentional or deliberate actions leading to the failure, suggesting it was an accidental design or manufacturing flaw that could potentially cause a fire hazard [91123]. |
| Duration |
unknown |
The article does not mention any software failure incident related to the Ford Ranger's HVAC system. Therefore, the duration of the software failure incident in this case is unknown. |
| Behaviour |
crash, other |
(a) crash: The software failure incident related to the Ford Ranger's HVAC system is not described as a crash where the system loses state and does not perform any of its intended functions [91123].
(b) omission: The article does not mention the software failure incident as an omission where the system omits to perform its intended functions at an instance(s) [91123].
(c) timing: The software failure incident is not related to timing issues where the system performs its intended functions correctly but too late or too early [91123].
(d) value: The software failure incident is not described as a value failure where the system performs its intended functions incorrectly [91123].
(e) byzantine: The software failure incident is not characterized as a byzantine failure where the system behaves erroneously with inconsistent responses and interactions [91123].
(f) other: The software failure incident is related to a possible fire risk in the HVAC system of the Ford Ranger pickup trucks due to an electrical short, blower motor overheating, smoking, and potential fire hazard. This behavior does not fit into the categories of crash, omission, timing, value, or byzantine failures [91123]. |
