one_organization |
(a) The software failure incident related to the occupant sensor in the front passenger seat assembly causing the airbag to stay activated after a child or child seat is placed up front has happened at Rivian. The issue was first noticed by Rivian in March, leading to a recall being initiated for 502 examples of the Rivian R1T electric pickup truck [128398].
(b) There is no information in the provided article about the software failure incident happening at other organizations or with their products and services. |
| Phase (Design/Operation) |
design |
(a) The software failure incident in this case is related to the design phase. The article mentions that the issue with the front passenger seat assembly in the Rivian R1T electric pickup truck stems from the occupant sensor not being calibrated correctly. This design flaw could cause the airbag to stay activated after a child or child seat is placed in the front passenger seat, increasing the risk of injury in the event of a crash. The problem was identified during testing, indicating a failure introduced during the development or design phase of the system [128398].
(b) There is no information in the provided article indicating that the software failure incident was due to factors introduced by the operation or misuse of the system. |
| Boundary (Internal/External) |
within_system |
(a) within_system: The software failure incident in the article is within the system. The issue stems from the occupant sensor in the front passenger seat assembly of the Rivian R1T electric pickup truck. The affected vehicles have seats that may not be calibrated correctly, causing the airbag to stay activated after a child or child seat is placed up front. This issue was discovered by Rivian in March due to problems with occupant sensor performance, leading to a recall being initiated [128398]. |
| Nature (Human/Non-human) |
non-human_actions, human_actions |
(a) The software failure incident in this case is not related to non-human actions but rather to a calibration issue with the occupant sensor in the front passenger seat assembly. The affected vehicles have seats that may not be calibrated correctly, leading to the airbag staying activated after a child or child seat is placed up front. This issue was identified by Rivian and a third-party testing company, indicating that the contributing factors were not introduced without human participation [128398].
(b) The software failure incident can be attributed to human actions as the calibration issue with the occupant sensor in the front passenger seat assembly was likely introduced during the manufacturing or assembly process. The incorrect calibration of the sensor was a result of human actions during the production of the affected vehicles. Additionally, the decision to initiate a recall and replace the passenger seats with the correct sensor calibrations was a human action taken by Rivian in response to the identified issue [128398]. |
| Dimension (Hardware/Software) |
hardware |
(a) The software failure incident in the article is related to hardware. The issue stems from the occupant sensor in the front passenger seat assembly not being calibrated correctly, which could cause the airbag to stay activated after a child or child seat is placed up front. This hardware-related failure could increase the risk of injury in the event of a crash [128398]. |
| Objective (Malicious/Non-malicious) |
non-malicious |
(a) The software failure incident described in Article 128398 is non-malicious. The issue with the occupant sensor in the front passenger seat assembly of the Rivian R1T electric pickup truck was due to seats not being calibrated correctly, causing the airbag to stay activated after a child or child seat is placed up front. This was identified as a safety concern that could increase the risk of injury in the event of a crash. The problem was discovered by Rivian itself in March, and a recall was initiated after third-party testing confirmed the issue. The fix involved swapping out the passenger seat for one with the correct sensor calibrations, and the company recommended not placing children or child seats in the front row until the solution was implemented [128398]. |
| Intent (Poor/Accidental Decisions) |
unknown |
(a) The software failure incident in the article is not related to poor decisions but rather to a technical issue with the occupant sensor in the front passenger seat assembly of the Rivian R1T electric pickup truck. The issue was identified as the seats not being calibrated correctly, leading to the airbag potentially staying activated after a child or child seat is placed in the front seat, increasing the risk of injury in the event of a crash [128398].
(b) The software failure incident was not caused by accidental decisions but rather by a technical fault in the calibration of the occupant sensor in the front passenger seat assembly of the affected vehicles [128398]. |
| Capability (Incompetence/Accidental) |
accidental |
(a) The software failure incident in the article is not related to development incompetence. The issue with the occupant sensor in the front passenger seat assembly of the Rivian R1T electric pickup truck was identified through testing and was determined to be a calibration issue rather than a result of development incompetence [128398].
(b) The software failure incident in the article is more aligned with an accidental introduction of contributing factors. The issue with the occupant sensor calibration in the front passenger seat assembly was not intentional but rather an accidental oversight that led to the airbag potentially staying activated when a child or child seat is placed in the front seat, increasing the risk of injury in the event of a crash [128398]. |
| Duration |
temporary |
(a) The software failure incident described in the article is temporary. The issue with the occupant sensor in the front passenger seat assembly of the Rivian R1T electric pickup trucks was identified as a calibration problem that could cause the airbag to stay activated incorrectly after a child or child seat is placed in the front seat. This issue was not a permanent failure but rather a specific problem with the calibration of the sensor, leading to the airbag activation issue. The company initiated a recall to address this specific problem by swapping out the passenger seat with the correct sensor calibrations, indicating that the failure was not a permanent one but rather a temporary issue that could be rectified through a specific fix [128398]. |
| Behaviour |
value |
(a) crash: The software failure incident described in the article is not related to a crash where the system loses state and does not perform any of its intended functions. The issue with the occupant sensor in the front passenger seat assembly in the Rivian R1T electric pickup trucks does not result in a complete system failure where it stops functioning altogether [128398].
(b) omission: The software failure incident is not due to the system omitting to perform its intended functions at an instance(s). The issue with the occupant sensor in the front passenger seat assembly is related to incorrect calibration, which could cause the airbag to stay activated after a child or child seat is placed in the front seat, rather than omitting its function entirely [128398].
(c) timing: The software failure incident is not due to the system performing its intended functions correctly but at the wrong time (too late or too early). The issue with the occupant sensor in the front passenger seat assembly is not about timing but rather about incorrect calibration affecting the airbag activation [128398].
(d) value: The software failure incident is related to the system performing its intended functions incorrectly. The problem with the occupant sensor in the front passenger seat assembly in the Rivian R1T electric pickup trucks is due to seats that may not be calibrated correctly, leading to the airbag staying activated when it should not be, potentially increasing the risk of injury in a crash [128398].
(e) byzantine: The software failure incident is not characterized by the system behaving erroneously with inconsistent responses and interactions. The issue with the occupant sensor in the front passenger seat assembly is more straightforward, involving a calibration problem that affects the airbag activation based on the presence of a child or child seat [128398].
(f) other: The software failure incident does not exhibit any other behavior outside of the options provided. The issue with the occupant sensor in the front passenger seat assembly is specifically related to incorrect calibration causing the airbag to stay activated when it should be deactivated in the presence of a child or child seat, leading to a potential safety risk [128398]. |
