| Boundary (Internal/External) |
within_system |
(a) within_system: The software failure incident related to the steering system malfunction in the Infiniti Q50 sedan was due to a software glitch within the system itself. The article mentions that the direct adaptive steering system could malfunction in certain rare circumstances just after starting the vehicle when a software glitch occurs, leading to a lack of steering responsiveness and a change in turning radius [45355].
(b) outside_system: The software failure incident was not attributed to contributing factors originating from outside the system in the articles provided. |
| Nature (Human/Non-human) |
non-human_actions |
(a) The software failure incident in this case was due to non-human actions, specifically a software glitch in the direct adaptive steering system of the Infiniti Q50 sedan. The malfunction could occur in certain rare circumstances just after starting the vehicle, leading to a lack of steering responsiveness and a change in turning radius. This glitch was not introduced by human actions but was a result of the software itself [45355].
(b) There is no information in the provided article indicating that the software failure incident was due to contributing factors introduced by human actions. |
| Dimension (Hardware/Software) |
hardware, software |
(a) The software failure incident in the article is related to hardware. The article mentions that the steering system key to the Q50 sedan's autonomous driving capabilities could malfunction due to a software glitch, leading to a lack of steering responsiveness and a change in turning radius. This issue is attributed to the direct adaptive steering system in the vehicle, indicating a hardware-related problem [45355].
(b) The software failure incident is also related to software. The article specifically states that the malfunction in the steering system is caused by a software glitch that occurs just after starting the vehicle. This software glitch can impact the steering responsiveness and turning radius, highlighting a software-related contributing factor to the failure incident [45355]. |
| Objective (Malicious/Non-malicious) |
non-malicious |
(a) The software failure incident related to the Infiniti Q50 steering system was non-malicious. The failure was attributed to a software glitch that could lead to a lack of steering responsiveness and a change in turning radius, particularly in certain rare circumstances just after starting the vehicle. This glitch was not introduced with the intent to harm the system but was a technical issue that affected the autonomous driving capabilities of the vehicle [45355]. |
| Intent (Poor/Accidental Decisions) |
accidental_decisions |
(a) The software failure incident related to the Infiniti Q50's steering system malfunction was not explicitly attributed to poor decisions in the articles. The incident was described as a result of a software glitch that could lead to a lack of steering responsiveness and a change in turning radius, particularly just after starting the vehicle. The focus was more on the technical aspect of the malfunction rather than poor decisions.
(b) The software failure incident related to the Infiniti Q50's steering system malfunction was primarily attributed to accidental decisions or mistakes. The article mentioned that the direct adaptive steering system could malfunction in certain rare circumstances due to a software glitch, leading to issues with steering responsiveness and turning radius. This indicates that the failure was more likely a result of unintended consequences or mistakes rather than poor decisions. |
| Capability (Incompetence/Accidental) |
development_incompetence, accidental |
(a) The software failure incident related to development incompetence is evident in the article as it mentions a software glitch in the direct adaptive steering system of the Infiniti Q50 sedan. The malfunction could occur "just after starting the vehicle" due to a lack of steering responsiveness and a change in turning radius caused by the software glitch [45355].
(b) The software failure incident related to accidental factors is also highlighted in the article. It mentions that the electric steering system of the 2014 model year Q50s could be disabled at freezing temperatures, indicating an accidental failure scenario [45355]. |
| Duration |
temporary |
The software failure incident related to the steering system malfunction in the Infiniti Q50 sedan can be categorized as a temporary failure. The article mentions that the malfunction occurs "in certain rare circumstances, just after starting the vehicle" due to a software glitch, leading to a lack of steering responsiveness and a change in turning radius [45355]. This indicates that the failure is not permanent but occurs under specific conditions, making it a temporary issue. |
| Behaviour |
crash, omission, timing, value, other |
(a) crash: The software glitch in the direct adaptive steering system of the Infiniti Q50 could lead to a lack of steering responsiveness and a change in turning radius, potentially causing the system to crash and not perform its intended functions [45355].
(b) omission: The software glitch in the steering system could result in the system omitting to perform its intended functions, particularly just after starting the vehicle, which could lead to a lack of steering responsiveness [45355].
(c) timing: The software glitch could cause the steering system to malfunction in certain rare circumstances, just after starting the vehicle, indicating a timing issue where the system may perform its intended functions but at the wrong time [45355].
(d) value: The software glitch could lead to the steering system performing its intended functions incorrectly, resulting in a lack of steering responsiveness and a change in turning radius, which could be considered a value-related failure [45355].
(e) byzantine: The article does not specifically mention the steering system exhibiting inconsistent responses or interactions that would classify as a byzantine failure.
(f) other: The software glitch causing a lack of steering responsiveness and a change in turning radius could be considered a functional anomaly that does not fit precisely into the crash, omission, timing, or value categories, representing another type of behavior in the software failure incident [45355]. |
