(b) The software failure incident is specifically due to a software flaw causing a breakdown of the eCall system, which is designed to automatically contact emergency responders in the event of a serious accident. This flaw originates in the software of the system, leading to the recall of 59,000 Tesla vehicles globally [130421].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident related to the Tesla models Y and 3 was non-malicious. The article mentions that the recall was due to a fault in the automatic emergency call system, specifically a software flaw causing a breakdown of the eCall feature. This feature is designed to automatically contact emergency responders in the event of a serious accident. The German road traffic agency identified this software glitch as the reason for the recall affecting 59,000 vehicles globally [130421].
Intent (Poor/Accidental Decisions) poor_decisions (a) The software failure incident related to the Tesla models Y and 3 automatic emergency call system was due to a software flaw causing a breakdown of the eCall feature, which is designed to automatically contact emergency responders in the event of a serious accident. This flaw was identified by Germany's road traffic agency, leading to the recall of 59,000 vehicles globally [130421]. The incident can be attributed to poor decisions in the software development process that introduced the flaw affecting the critical emergency response feature.
Capability (Incompetence/Accidental) accidental (a) The software failure incident in this case was not explicitly attributed to development incompetence. The article mentions a software flaw causing a breakdown of the eCall system in Tesla models Y and 3, leading to the recall of 59,000 vehicles globally. The focus is on the technical issue with the automatic emergency call system rather than incompetence in development [130421]. (b) The software failure incident was accidental in nature. The article describes a software flaw in the automatic emergency call system of Tesla models Y and 3, which was causing a breakdown of the eCall feature. This issue was not intentional but rather an accidental fault that led to the recall of 59,000 vehicles globally [130421].
Duration temporary The software failure incident mentioned in the article is temporary. The article states that the recall of Tesla models Y and 3 was due to a fault in the automatic emergency call system, specifically a software flaw causing a breakdown of the eCall feature.
