| Postmortem Analysis | |
|---|---|
| Timeline | 1. The software failure incident involving quality issues with Tesla vehicles, specifically missing bolts and other potentially dangerous problems, was reported in an article published on 2021-01-07 [110462]. 2. Based on the information provided in the article, there are no direct mentions or clues about the specific timing of the software failure incident. Therefore, the timeline of the incident cannot be estimated accurately. |
| System | 1. Upper control arm of the Model Y 2. Charge port door assembly 3. Mounting bolts on Tesla vehicles These components failed in the software failure incident reported in Article 110462. |
| Responsible Organization | unknown |
| Impacted Organization | 1. National Highway Traffic Safety Administration (NHTSA) [110462] 2. Tesla owners [110462] 3. Repair shops contracted by Tesla [110462] |
| Software Causes | unknown |
| Non-software Causes | 1. Missing nyloc nut in the upper control arm of the Model Y, leading to potential front suspension issues [110462]. 2. Missing bolts in delivered vehicles, causing parts like bumpers to fall off while in motion [110462]. 3. Uneven charge port door requiring adjustments with a dead hammer and touch-up paint [110462]. |
| Impacts | 1. Missing nyloc nut in the upper control arm of the Model Y led to potential front suspension issues, including the ball joint slipping and the suspension coming loose while the car is in motion [110462]. 2. Uneven charge port door issues required using a dead hammer to adjust the metal sheet, potentially causing cosmetic damage and safety concerns [110462]. 3. Delivery of vehicles with missing bolts resulted in incidents where bumpers fell off and seats were not properly secured, leading to safety hazards and damage [110462]. |
| Preventions | 1. Implementing thorough quality control checks during the manufacturing process to ensure all components are properly installed and secured [110462]. 2. Conducting comprehensive inspections and testing of vehicles before delivery to customers to identify and rectify any missing parts or defects [110462]. 3. Enhancing communication and coordination between different departments involved in the vehicle manufacturing process to prevent oversights and errors in assembly [110462]. |
| Fixes | 1. Conducting thorough quality checks during the manufacturing process to ensure all components are properly installed and secured [110462]. | References | unknown |
| Category | Option | Rationale |
|---|---|---|
| Recurring | unknown | The articles do not mention any software failure incidents related to either one_organization or multiple_organization. |
| Phase (Design/Operation) | design | Unknown |
| Boundary (Internal/External) | unknown | The articles do not mention any software failure incident related to the boundary of the failure incident. |
| Nature (Human/Non-human) | non-human_actions | <Article 110462> provides information about quality issues with Tesla vehicles, including missing bolts and other potentially dangerous problems. These issues are not related to software failures but rather to manufacturing and design flaws in the vehicles themselves. Therefore, there is no mention of software failure incidents in this article. |
| Dimension (Hardware/Software) | unknown | The articles do not mention any software failure incident related to hardware or software issues. Therefore, the information to answer this question is 'unknown'. |
| Objective (Malicious/Non-malicious) | unknown | The articles do not mention any software failure incident related to either malicious or non-malicious factors. Therefore, the information needed to determine the objective of the software failure incident is unknown. |
| Intent (Poor/Accidental Decisions) | unknown | The articles do not mention any software failure incident related to poor decisions or accidental decisions. |
| Capability (Incompetence/Accidental) | unknown | Unknown |
| Duration | unknown | Unknown |
| Behaviour | omission, other | (a) crash: The articles do not mention any software failure incident related to a crash where the system loses state and does not perform any of its intended functions. (b) omission: The articles describe instances where Tesla vehicles were delivered with missing bolts, such as mounting bolts missing from the rear of the Tesla, resulting in the bumper falling off while the vehicle was in motion [110462]. (c) timing: The articles do not mention any software failure incident related to timing, where the system performs its intended functions correctly but too late or too early. (d) value: The articles do not mention any software failure incident related to value, where the system performs its intended functions incorrectly. (e) byzantine: The articles do not mention any software failure incident related to a byzantine behavior, where the system behaves erroneously with inconsistent responses and interactions. (f) other: The behavior described in the articles is related to hardware issues and missing components in Tesla vehicles, such as missing nyloc nuts in the upper control arm, missing bolts, and uneven charge port doors. These issues are more related to manufacturing and assembly quality control rather than software failures [110462]. |

| Consequence | no_consequence | The articles do not mention any software failure incident related to consequences such as death, harm, basic needs impact, property damage, delay, or non-human entities being impacted. There is also no mention of theoretical consequences or other consequences resulting from the software failure incident reported in the articles. Therefore, the consequence of the software failure incident in the articles is 'no_consequence' as there were no real observed consequences discussed in the provided text [110462]. |
