one_organization |
a) The software failure incident related to spider webs causing airbags to inflate accidentally has happened before at Toyota. In 2011, Mazda also had a similar issue where spiders built webs inside a vent for the petrol tank, leading to vent blockages and potential fires [22787].
b) The software failure incident related to spider webs causing issues in vehicles has not been reported to have occurred at multiple organizations in the articles provided. |
| Phase (Design/Operation) |
design |
Unknown |
| Boundary (Internal/External) |
within_system |
(a) within_system: The software failure incident related to the Toyota recall of almost a million cars due to spider webs triggering airbags to inflate and potentially causing drivers to lose control is a within_system failure. The issue originated from within the cars' systems, specifically with the air conditioning condenser unit housing where spider webs could cause a blockage in a drainage tube, leading to water dripping down into the airbag control module and potentially causing the airbag to inflate suddenly [22787]. |
| Nature (Human/Non-human) |
non-human_actions |
(a) The software failure incident occurring due to non-human actions:
The software failure incident in this case was not directly caused by non-human actions. The issue stemmed from spider webs causing a blockage in a drainage tube connected to the cars' air conditioning condenser, leading to water dripping down into the airbag control module and potentially causing the airbags to inflate accidentally [22787].
(b) The software failure incident occurring due to human actions:
The software failure incident in this case was not directly caused by human actions. The root cause of the issue was attributed to spider webs blocking the drainage tube, which was a non-human factor introduced by the spiders inhabiting the warm and dark air conditioning condenser unit housing in the vehicles [22787]. |
| Dimension (Hardware/Software) |
hardware |
(a) The software failure incident occurring due to hardware:
- The article reports that Toyota recalled almost a million cars because spider webs could trigger airbags to inflate and cause drivers to lose control. The issue stemmed from spider webs causing a blockage in a drainage tube that comes from the cars' air conditioning condenser, leading to problems with the airbag control module and potential loss of power steering [22787].
(b) The software failure incident occurring due to software:
- The article does not mention any software-related contributing factors that originated in software for the reported Toyota recall incident. |
| Objective (Malicious/Non-malicious) |
non-malicious |
(a) The software failure incident related to the Toyota recall of almost a million cars due to spider webs triggering airbags to inflate and potentially cause drivers to lose control is categorized as non-malicious. The issue stemmed from spider webs causing a blockage in a drainage tube connected to the cars' air conditioning condenser, leading to unintended consequences such as airbags inflating and warning lights showing on the dashboard [22787]. The company identified the root cause as the spider webs causing a short circuit in the airbag control module, rather than any intentional malicious activity. |
| Intent (Poor/Accidental Decisions) |
unknown |
The software failure incident related to the Toyota recall of almost a million cars due to spider webs triggering airbags to inflate and potentially causing drivers to lose control does not directly involve software failure. The issue was attributed to spider webs causing blockages in a drainage tube connected to the cars' air conditioning condenser, leading to airbag malfunctions and warning lights showing on the dashboard. Therefore, the incident does not fall under the categories of poor_decisions or accidental_decisions related to software failure. |
| Capability (Incompetence/Accidental) |
accidental |
(a) The software failure incident related to development incompetence is not mentioned in the provided articles.
(b) The software failure incident related to accidental factors is described in the articles. Toyota recalled almost a million cars because spider webs could trigger airbags to inflate and cause drivers to lose control. The issue was caused by spider webs blocking a drainage tube that comes from the cars' air conditioning condenser, leading to water dripping down into the airbag control module, which could short circuit and cause the airbag to inflate suddenly [22787]. This incident was accidental and not due to intentional actions or development incompetence. |
| Duration |
unknown |
The articles do not mention any software failure incident related to the Toyota recall of almost a million cars due to spider webs triggering airbags to inflate. Therefore, the duration of the software failure incident in this case is unknown. |
| Behaviour |
crash, omission, value, other |
(a) crash: The software failure incident in this case can be categorized as a crash. The article mentions that the issue with spider webs causing a blockage in a drainage tube from the cars' air conditioning condenser can lead to the airbag control module short-circuiting, potentially causing the airbag to inflate suddenly [22787].
(b) omission: The software failure incident can also be categorized as an omission. The article states that the blockage caused by spider webs can lead to water dripping down into the airbag control module, resulting in a warning light displaying on the dashboard or, more seriously, causing the airbag to inflate suddenly [22787].
(c) timing: There is no specific mention of the software failure incident being related to timing issues in the articles.
(d) value: The software failure incident can be categorized as a value failure. The article explains that the blockage caused by spider webs can result in the airbag control module short-circuiting, potentially leading to the airbag inflating suddenly, which is an incorrect function of the system [22787].
(e) byzantine: There is no indication in the articles that the software failure incident exhibited behaviors of a byzantine failure.
(f) other: The software failure incident could also be categorized as an "other" behavior. This is because the issue with spider webs causing a blockage in the drainage tube from the cars' air conditioning condenser is not a typical software failure scenario but rather a unique case where a physical obstruction leads to a malfunction in the system [22787]. |
