Software Taxonomy of Faults

Category Option Rationale
Recurring unknown (a) The software failure incident having happened again at one_organization: The article does not mention any previous incidents of a similar nature happening again within the same organization (Fiat Chrysler) or with its products and services. Therefore, there is no information available to suggest that this specific software failure incident has occurred before within Fiat Chrysler or with its products and services. [68038] (b) The software failure incident having happened again at multiple_organization: The article does not provide any information about similar incidents happening again at other organizations or with their products and services. Hence, there is no mention of this specific software failure incident occurring at multiple organizations. [68038]
Phase (Design/Operation) design (a) The software failure incident in the article is related to the design phase. The failure occurred due to an over-the-air update sent by Fiat Chrysler Automobiles to certain Uconnect infotainment systems, which resulted in the systems getting stuck in an endless bootloop, affecting various features like climate settings, seat heater, and the backup camera. This issue was a result of the update going wrong, indicating a failure introduced during the system development or update process [68038]. (b) The article does not provide information indicating that the software failure incident was related to the operation phase or misuse of the system.
Boundary (Internal/External) within_system From the provided article [68038], the software failure incident related to the Fiat Chrysler Uconnect update causing infotainment systems to go into an endless bootloop can be analyzed as follows: (a) within_system: The failure seems to be within the system itself as it was triggered by an over-the-air update sent by Fiat Chrysler Automobiles to the Uconnect infotainment systems in certain vehicles. The issue caused the systems to continuously restart, affecting various functionalities like climate settings, seat heaters, and the backup camera, which are all managed by the Uconnect system. (b) outside_system: There is no explicit mention in the article of the failure being caused by contributing factors originating from outside the system. The incident is primarily described as a result of the faulty over-the-air update sent by the company, indicating an internal system issue rather than an external factor.
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident in the Fiat Chrysler Uconnect infotainment systems was likely due to non-human actions, specifically related to the over-the-air update sent by Fiat Chrysler Automobiles. The update went wrong and caused the infotainment systems to enter an endless bootloop, restarting the screen every minute or so. This indicates a failure introduced by the update process or software code rather than direct human actions [68038]. (b) However, human actions were involved in responding to the incident. Owners took to Twitter to express their grievances, and Uconnect's customer support acknowledged the issue and promised an investigation and resolution. This shows that human actions were involved in the communication and response to the software failure incident [68038].
Dimension (Hardware/Software) hardware, software (a) The software failure incident in the article is related to hardware. The article mentions that Fiat Chrysler sent an over-the-air update to certain vehicles' Uconnect infotainment systems, which resulted in the systems being forced into an endless bootloop, where the screen restarts every minute or so. This indicates that the issue originated from the over-the-air update affecting the hardware of the infotainment systems [68038].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident described in the article does not indicate any malicious intent. It appears to be a non-malicious failure caused by an error in the over-the-air update sent by Fiat Chrysler Automobiles, leading to infotainment systems getting stuck in a bootloop. The article mentions that the company acknowledged the issue and promised an investigation and resolution, indicating a lack of malicious intent [68038].
Intent (Poor/Accidental Decisions) poor_decisions, accidental_decisions From the provided article [68038], the software failure incident related to the Fiat Chrysler Uconnect over-the-air update can be attributed to both poor decisions and accidental decisions: 1. Poor Decisions: The incident can be linked to poor decisions as Fiat Chrysler Automobiles sent out an over-the-air update that ended up causing issues with the Uconnect infotainment systems in certain vehicles. This decision led to the systems getting stuck in an endless bootloop, affecting various functionalities like climate settings, seat heaters, and the backup camera. The company's acknowledgment of the error and the subsequent negative feedback on social media indicate a poor decision in rolling out the update without proper testing or safeguards in place. 2. Accidental Decisions: On the other hand, the incident also reflects accidental decisions or unintended consequences. The update was likely intended to improve or enhance the Uconnect systems in the vehicles, but it inadvertently caused the bootloop issue, disrupting the normal functioning of the infotainment systems. The fact that the problem was not universal, affecting some vehicles while leaving others unaffected, suggests an accidental outcome rather than a deliberate action. Therefore, the software failure incident involving the Fiat Chrysler Uconnect update appears to have elements of both poor decisions and accidental decisions contributing to the failure.
Capability (Incompetence/Accidental) development_incompetence, accidental (a) The software failure incident in the Fiat Chrysler Uconnect infotainment systems can be attributed to development incompetence. The over-the-air update sent by Fiat Chrysler resulted in many infotainment systems getting stuck in an endless bootloop, causing inconvenience to the vehicle owners. This issue showcases a lack of professional competence in the development and testing of the software update, leading to a significant disruption in the functionality of the Uconnect system [68038]. (b) Additionally, the incident can also be considered accidental as the update that caused the bootloop issue was likely not intentionally designed to cause such disruptions. It was an unintended consequence of the update deployment, highlighting how accidents or unintended consequences can lead to software failures [68038].
Duration temporary The software failure incident described in Article 68038 seems to fall under the category of a temporary failure. The article mentions that the over-the-air update sent by Fiat Chrysler caused certain Uconnect infotainment systems to enter an endless bootloop, where the screen restarts every minute or so. This indicates that the issue is ongoing but not permanent, as it is a result of the specific update rather than a fundamental flaw affecting all systems [68038].
Behaviour crash, omission, value, other (a) crash: The software failure incident described in the article is a crash where the Uconnect infotainment systems were forced into an endless bootloop, causing the screen to restart every minute or so, resulting in the system losing its state and not performing its intended functions [68038]. (b) omission: The failure incident can also be categorized as an omission since the affected Uconnect systems omitted to perform their intended functions, such as managing climate settings, setting the seat heater, and accessing the backup camera, due to the crash [68038]. (c) timing: The timing of the failure incident is not specifically mentioned in the article. (d) value: The failure incident can be attributed to a value failure as the Uconnect systems were performing their intended functions incorrectly after the update, leading to the loss of access to important features like the backup camera and climate settings [68038]. (e) byzantine: The byzantine behavior is not explicitly mentioned in the article. (f) other: The other behavior observed in this software failure incident is the inconvenience caused to users, as highlighted by the fact that owners took to Twitter to express their grievances and the company's acknowledgment of the error with a promise of investigation and resolution [68038].
