General Motors issued a recall for 5,141 Corvettes due to bad software controlling the frunk release button, which led to issues such as the frunk not closing properly despite alerts and the frunk release not working when the car is in sleep mode. The defect in the software design introduced risks of the frunk opening while driving and non-compliance with federal motor safety standards [104371]. (b) The software failure incident is not related to the operation phase or misuse of the system.
Boundary (Internal/External) within_system (a) within_system: The software failure incident with the 2020 Chevrolet Corvette Stingray's frunk was due to bad software to control the frunk release button, which was a part of the internal system of the vehicle [104371]. The defect in the software caused issues such as the frunk not closing properly, leading to potential risks while driving, and the frunk release not working when the vehicle was in sleep mode, which are all internal system-related failures.
Nature (Human/Non-human) non-human_actions (a) The software failure incident in the 2020 Chevrolet Corvette Stingray's frunk was due to non-human actions. The issue stemmed from bad software that controlled the frunk release button, leading to potential risks such as the frunk flipping open while driving and the internal frunk release being disengaged during sleep mode, which could trap someone inside the frunk [104371].
Dimension (Hardware/Software) hardware, software (a) The software failure incident in the article is related to hardware. General Motors issued a recall for 5,141 Chevrolet Corvettes due to bad software controlling the frunk release button. The defect in the software can cause the frunk to flip open while driving, increasing the risk of a crash. Additionally, the software issue can lead to the Corvette entering a "sleep mode" after 10 minutes parked and stationary, which disengages the internal frunk release, potentially trapping someone in the frunk. The remedy for this hardware-related software issue involves updating the software in the body control module to ensure the release always works and limit the driver's speed if the frunk isn't closed properly [104371].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident described in Article 104371 is non-malicious. The failure was due to a defect in the software controlling the frunk release button of the 2020 Chevrolet Corvette Stingray. This defect could lead to safety risks such as the frunk opening while driving or the inability to release the frunk if someone is trapped inside. General Motors issued a recall to address this software issue, indicating that the failure was not caused by malicious intent but rather by a technical flaw in the software [104371].
Intent (Poor/Accidental Decisions) unknown (a) The software failure incident related to the 2020 Chevrolet Corvette Stingray's frunk was not due to poor decisions but rather a defect in the software that controlled the frunk release button. General Motors issued a recall for 5,141 Corvettes built with bad software that led to issues such as the frunk not closing properly despite alerts, the frunk flipping open while driving, and the internal frunk release not working when the vehicle enters sleep mode [104371]. This indicates that the failure was not a result of poor decisions but rather a software defect.
Capability (Incompetence/Accidental) development_incompetence (a) The software failure incident in the 2020 Chevrolet Corvette Stingray's frunk was due to development incompetence. General Motors issued a recall for 5,141 Corvettes built with bad software to control the frunk release button.
