Software Taxonomy of Faults

Category Option Rationale
Recurring unknown The provided article does not mention any software failure incident related to either one_organization or multiple_organization. Therefore, the information to answer this question is 'unknown'.
Phase (Design/Operation) operation (a) The article does not mention any software failure incident related to the design phase, such as contributing factors introduced by system development, system updates, or procedures to operate or maintain the system. (b) The software failure incident mentioned in the article is related to the operation phase. The defective impellers in the fuel pumps installed in the vehicles could result in a loss of engine power or vehicle stalling, potentially increasing the risk of a crash due to the operation of the vehicles [101939].
Boundary (Internal/External) within_system (a) The software failure incident related to the fuel pumps in Acura and Honda vehicles is within_system. The failure is attributed to defective impellers within the fuel pumps installed in the vehicles, which could lead to a loss of engine power or vehicle stalling, potentially increasing the risk of a crash [101939].
Nature (Human/Non-human) non-human_actions (a) The software failure incident related to non-human actions in this case is the defective impellers in the fuel pumps installed in the 2018-2020 model year vehicles from Acura and Honda. This defect could lead to a loss of engine power or vehicle stalling, potentially increasing the risk of a crash. The automakers are recalling the vehicles to replace the fuel pumps to address this issue [101939]. (b) The software failure incident related to human actions is not explicitly mentioned in the article.
Dimension (Hardware/Software) hardware (a) The software failure incident related to hardware: - The article mentions that Acura and Honda are recalling vehicles to replace their fuel pumps due to defective impellers, which are hardware components. This defect in the hardware could lead to a loss of engine power or vehicle stalling, potentially increasing the risk of a crash [101939]. (b) The software failure incident related to software: - The article does not mention any software-related issues contributing to the failure incident. Therefore, there is no information provided regarding a software failure originating from software-related factors.
Objective (Malicious/Non-malicious) non-malicious The software failure incident described in the article does not involve any malicious intent. The issue with the fuel pumps in the Acura and Honda vehicles is attributed to defective impellers, which could lead to a loss of engine power or vehicle stalling, potentially increasing the risk of a crash. This indicates a non-malicious software failure incident [101939].
Intent (Poor/Accidental Decisions) unknown <Article 101939> The software failure incident related to the fuel pump recall for Acura and Honda vehicles is not directly attributed to software issues. The recall is due to defective impellers in the fuel pumps, which could lead to a loss of engine power or vehicle stalling, potentially increasing the risk of a crash. This issue is more related to a manufacturing defect in the physical components rather than a software failure incident. Therefore, the intent of the software failure incident in this case is unknown as it does not fall under the categories of poor decisions or accidental decisions related to software. </Article 101939>
Capability (Incompetence/Accidental) unknown Unknown
Duration unknown The articles do not mention any software failure incident related to the duration of the failure being permanent or temporary. Therefore, the information to determine whether the software failure incident was permanent or temporary is unknown.
Behaviour crash, other (a) crash: The software failure incident in the article is related to a potential crash of the vehicles due to defective fuel pumps, which could result in a loss of engine power or vehicle stalling, potentially increasing the risk of a crash [101939]. (b) omission: There is no specific mention of the software failure incident being related to the system omitting to perform its intended functions at an instance(s) in the article [101939]. (c) timing: The software failure incident is not described as a failure due to the system performing its intended functions correctly, but too late or too early in the article [101939]. (d) value: The software failure incident is not related to the system performing its intended functions incorrectly in the article [101939]. (e) byzantine: The software failure incident is not described as a failure due to the system behaving erroneously with inconsistent responses and interactions in the article [101939]. (f) other: The software failure incident in the article is specifically related to a potential crash risk due to defective fuel pumps in the vehicles, which is not covered by the options provided [101939].
