(b) The software failure incident was also related to the operation phase. Customers experienced the impact of the software bug as their vehicles' systems were affected, leading to complaints flooding Lexus's social media accounts. The company had to provide instructions for owners to reset their vehicle's computer by disconnecting the battery or bringing the vehicle to a dealer for a system reset, indicating operational issues faced by the users [45064]. |
| Boundary (Internal/External) |
within_system |
(a) The software failure incident reported in the articles was primarily within the system. The malfunction in vehicles' GPS, climate control, infotainment systems, and hands-free phone functions was caused by a software bug within the company's traffic and weather service data broadcast [45064]. The glitch led to the continuous rebooting of the subscription-based "Enform" system, rendering it unusable and drawing complaints from drivers. The company had to rush to fix the bug by offering solutions like forcing a reset of the vehicle's computer and bringing the vehicles to dealers for system resets. The incident highlights how cars, like other technological devices, are becoming more reliant on software and are susceptible to software glitches originating from within the system. |
| Nature (Human/Non-human) |
non-human_actions, human_actions |
(a) The software failure incident in this case was primarily due to non-human actions. The malfunction was caused by errant data broadcast by the company's traffic and weather service, which confounded the vehicles' infotainment system, leading to continuous reboots and rendering it unusable [45064].
(b) Human actions were involved in the resolution of the software failure incident. The company advised owners to force a reset of their vehicle's computer by disconnecting the 12-volt battery for at least 5 minutes or bring their vehicles to a Lexus dealer for a system reset. Additionally, the company halted the offending data stream and offered fixes for the bug, showing human intervention in addressing the issue [45064]. |
| Dimension (Hardware/Software) |
software |
(a) The software failure incident reported in the articles was primarily due to a software bug that caused malfunctions in vehicles' GPS, climate control, infotainment systems, and hands-free phone functions. The glitch was caused by errant data broadcast by the company's traffic and weather service, which affected the Enform infotainment system in Lexus vehicles and the Toyota Land Cruiser. The bug made the Enform system continuously reboot itself, rendering it unusable [Article 45064].
(b) The software failure incident was specifically attributed to a software bug that affected the Enform infotainment system in Lexus vehicles and the Toyota Land Cruiser. The glitch caused malfunctions in various systems, including GPS, climate control, infotainment, and hands-free phone functions. The bug was remedied by forcing a reset of the vehicle's computer or bringing the vehicle to a dealer for a system reset [Article 45064]. |
| Objective (Malicious/Non-malicious) |
non-malicious |
(a) The software failure incident described in the articles is non-malicious. It was caused by a software bug in the company's traffic and weather service that led to a malfunction in vehicles' GPS, climate control, infotainment systems, and hands-free phone functions [45064]. The glitch resulted in the Enform infotainment system continuously rebooting itself, rendering it unusable and causing inconvenience to drivers. The company rushed to fix the bug and offered solutions to reset the system, indicating that the failure was not due to malicious intent but rather a technical issue. |
| Intent (Poor/Accidental Decisions) |
accidental_decisions |
The software failure incident reported in the articles seems to align more with the category of accidental_decisions rather than poor_decisions. The incident was caused by an errant data broadcast by the company's traffic and weather service, which led to the malfunction of the Enform infotainment system in Lexus vehicles and the Toyota Land Cruiser [45064]. This issue was not a result of a deliberate poor decision but rather an unintended mistake that caused the system to continuously reboot itself, rendering it unusable for drivers. The company rushed to fix the bug and offered solutions to customers affected by the glitch, indicating that the failure was more of an accidental occurrence rather than a result of poor decisions. |
| Capability (Incompetence/Accidental) |
accidental |
(a) The software failure incident in the articles seems to be more related to accidental factors rather than development incompetence. The incident was caused by errant data broadcast by the company's traffic and weather service, which led to the malfunction in vehicles' GPS, climate control, infotainment systems, and hands-free phone functions [45064]. This indicates that the failure was not due to a lack of professional competence during development but rather an accidental introduction of problematic data that caused the glitch. |
| Duration |
temporary |
The software failure incident reported in Article 45064 was temporary. The incident was caused by errant data broadcast by the company's traffic and weather service, which affected the Enform infotainment system in Lexus vehicles and the Toyota Land Cruiser. The glitch made the Enform system continuously reboot itself, rendering it unusable. The company rushed to fix the bug and provided solutions for owners to reset their vehicle's computer, either by disconnecting the battery or visiting a Lexus dealer. The company also halted the offending data stream overnight to address the issue [45064]. |
| Behaviour |
crash, omission, value, other |
(a) crash: The software failure incident in the articles can be categorized as a crash. The malfunction in vehicles' GPS, climate control, infotainment systems, and hands-free phone functions caused the systems to continuously reboot themselves, rendering them unusable [45064].
(b) omission: The software failure incident can also be categorized as an omission. The glitch caused the omission of key functions such as the backup camera and hands-free phone functions in the affected vehicles [45064].
(c) timing: The software failure incident does not align with the timing category as there is no indication that the system performed its intended functions too late or too early [45064].
