Preventions To prevent the software failure incident of potential car overheating and catching on fire in the recalled Kia SUVs in Australia, the following measures could have been taken: 1. Implementing thorough software testing procedures during the development phase to identify and rectify any potential software issues before the vehicles are released to the market [129311]. 2. Conducting regular software quality assurance checks and audits to ensure the software components, such as the HVAC control unit software, operate within safe temperature limits and do not pose a risk of damage to critical vehicle components [129311]. 3. Enforcing a robust software update and maintenance schedule to promptly address any identified software vulnerabilities or risks, thereby preventing potential safety hazards like vehicle fires [129311].
Fixes 1. Updating the HVAC control unit software and inspecting the heater core element and connector could fix the software failure incident [129311].

Software Taxonomy of Faults

Category Option Rationale
Recurring unknown (a) The software failure incident has happened again at one_organization: - The article does not mention any previous incidents of a similar nature happening within the same organization (Kia) or with its products and services. Therefore, there is no indication that this specific software failure incident has occurred again within the same organization. (b) The software failure incident has happened again at multiple_organization: - The article does not provide information about similar incidents happening at other organizations or with their products and services. Hence, there is no mention of this specific software failure incident occurring at multiple organizations.
Phase (Design/Operation) design (a) The software failure incident in the Kia SUVs in Australia was due to a design issue. The recall notice mentioned that the Heater Core Element may operate at a higher than intended temperature due to a software issue, causing damage to the connector and potentially resulting in a vehicle fire. This indicates that the failure was introduced by a system development issue related to the software controlling the Heater Core Element [129311]. (b) The software failure incident was not attributed to operation or misuse factors but rather to a design flaw in the software controlling the Heater Core Element in the affected Kia SUV models.
Boundary (Internal/External) within_system (a) The software failure incident in the article is within_system. The failure is attributed to a software issue within the vehicles' HVAC control unit software, specifically related to the Heater Core Element operating at a higher than intended temperature due to a software issue, potentially causing damage to the connector and leading to a risk of vehicle fire [129311].
Nature (Human/Non-human) non-human_actions (a) The software failure incident in the article is attributed to a non-human action. The recall was issued due to a potential software risk in the Heater Core Element, which could operate at a higher than intended temperature causing damage to the connector, ultimately leading to a risk of the car overheating and catching on fire. This issue was identified as a software issue, indicating a failure introduced without human participation [129311].
Dimension (Hardware/Software) hardware, software (a) The software failure incident in the article is related to hardware. The recall notice mentioned that "Due to a software issue, the Heater Core Element may operate at a higher than intended temperature causing damage to connector" which indicates that the issue originates in the hardware component, the Heater Core Element, due to the software problem [129311].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident described in Article 129311 is non-malicious. The failure is attributed to a software issue related to the Heater Core Element operating at a higher than intended temperature due to a software issue, potentially causing damage to the connector and posing a risk of vehicle fire. The recall notice explicitly mentions that the issue is due to a software problem, indicating that the failure was not caused by malicious intent [129311].
Intent (Poor/Accidental Decisions) accidental_decisions The software failure incident related to the recall of Kia SUVs in Australia was due to a potential software risk that could cause the car to overheat and catch on fire. The failure was attributed to a software issue that caused the Heater Core Element to operate at a higher than intended temperature, leading to damage to the connector. This indicates that the software failure incident was more aligned with the category of 'accidental_decisions' rather than 'poor_decisions' as it was likely a mistake or unintended consequence of the software design or implementation [129311].
Capability (Incompetence/Accidental) accidental (a) The software failure incident in the article is not attributed to development incompetence. The issue is described as a potential software risk related to a higher than intended temperature in the Heater Core Element causing damage to a connector, which could result in a vehicle fire. The recall notice mentions a software issue leading to this potential risk, but it does not indicate any incompetence in the development process [129311]. (b) The software failure incident in the article is categorized more as an accidental failure. The issue is described as a potential software risk related to a higher than intended temperature in the Heater Core Element causing damage to a connector, which could result in a vehicle fire. This issue is not portrayed as intentional or deliberately introduced but rather as an unintended consequence of the software operation [129311].
Duration temporary The software failure incident described in Article 129311 is temporary. The article mentions that the issue is related to a software problem that causes the Heater Core Element to operate at a higher than intended temperature, potentially leading to vehicle overheating and fire. Kia has issued a recall for the affected SUV models and provided a fix that involves updating the HVAC control unit software and inspecting/replacing the Heater Core Element and connector. The repair is estimated to take approximately 45 minutes to complete, indicating that once the software is updated and the necessary components are inspected/replaced, the issue will be resolved [129311].
Behaviour value, other (a) crash: The software failure incident in the article is not described as a crash where the system loses state and does not perform any of its intended functions [129311]. (b) omission: The software failure incident does not involve the system omitting to perform its intended functions at an instance(s) [129311]. (c) timing: The software failure incident is not related to the system performing its intended functions correctly but too late or too early [129311]. (d) value: The software failure incident is due to the system performing its intended functions incorrectly, leading to a potential risk of the car overheating and catching on fire [129311]. (e) byzantine: The software failure incident is not described as the system behaving erroneously with inconsistent responses and interactions [129311]. (f) other: The behavior of the software failure incident is related to the system performing its intended functions incorrectly, specifically causing the Heater Core Element to operate at a higher than intended temperature, potentially resulting in damage to the connector and a vehicle fire [129311].
