| Recurring |
one_organization |
(a) The software failure incident related to the electronic parking brake problems in Jeep Cherokee SUVs has happened again within the same organization. The National Highway Traffic Safety Administration (NHTSA) mentioned that a previous recall was issued for the same group of Jeep Cherokees due to water leaks affecting the power liftgate, which is in a similar area of the vehicle where the EPB module is located. This indicates a recurrence of issues related to water damage affecting different modules in the vehicle [130137].
(b) The software failure incident related to the electronic parking brake problems in Jeep Cherokee SUVs has not been explicitly mentioned to have happened at multiple organizations in the provided article. |
| Phase (Design/Operation) |
design, operation |
(a) The software failure incident related to the design phase is evident in the article. The National Highway Traffic Safety Administration (NHTSA) investigation revealed that the electronic parking brake problems in over 1.3 million Jeep Cherokee SUVs were caused by water damage affecting the EPB module. The report stated that the EPB module is damaged by water leaking into the vehicle, leading to inadvertent activation of the parking brake while the vehicle is in motion, causing a stalling condition [130137].
(b) The software failure incident related to the operation phase is also highlighted in the article. The NHTSA investigation mentioned that the electronic parking brake issues were triggered by water leaks affecting the EPB module, which can activate while the Jeep is in motion. This indicates that the failure was influenced by the operation of the vehicle and the conditions it was exposed to during use [130137]. |
| Boundary (Internal/External) |
within_system |
(a) within_system: The software failure incident related to the electronic parking brakes in Jeep Cherokee SUVs was attributed to water damage affecting the EPB module within the vehicle. The NHTSA report mentioned that water leaking into the vehicle damaged the EPB module, leading to unintended activation of the parking brake while the vehicle is in motion, causing a stalling condition [130137]. This indicates that the failure originated from within the system itself, specifically due to water damage affecting the EPB module. |
| Nature (Human/Non-human) |
non-human_actions |
(a) The software failure incident in the Jeep Cherokee SUVs was attributed to water damage, specifically water leaking into the vehicle, which damaged the EPB module causing it to inadvertently activate and bring the vehicle to a stop. This non-human action of water damage was identified as the root cause of the electronic parking brake problems [130137].
(b) The article does not provide specific information about human actions contributing to the software failure incident. |
| Dimension (Hardware/Software) |
hardware |
(a) The software failure incident in the Jeep Cherokee SUVs was attributed to hardware-related issues. The National Highway Traffic Safety Administration (NHTSA) investigation found that water damage was to blame for the electronic parking brake problems. The EPB module was damaged by water leaking into the vehicle, leading to inadvertent activation of the parking brake while the vehicle is in motion, causing a stalling condition [130137].
Additionally, a previous recall was issued for the same group of Jeep Cherokees due to water leaks affecting the power liftgate. The liftgate module, which is located in a similar area of the vehicle as the EPB module, was at risk of catching fire as a result of water damage [130137]. |
| Objective (Malicious/Non-malicious) |
non-malicious |
(a) The software failure incident related to the electronic parking brakes in Jeep Cherokee SUVs was non-malicious. The failure was attributed to water damage causing the EPB module to activate inadvertently, leading to a stalling condition and bringing the vehicle to a stop. The National Highway Traffic Safety Administration (NHTSA) mentioned that water leaking into the vehicle damaged the EPB module, indicating a non-malicious cause for the issue [130137]. |
| Intent (Poor/Accidental Decisions) |
accidental_decisions |
The software failure incident related to the electronic parking brake issues in the Jeep Cherokee SUVs appears to be more aligned with the category of "accidental_decisions" rather than "poor_decisions." The incident was attributed to water damage causing the EPB module to activate inadvertently, leading to a stalling condition in the vehicle. This issue was specifically mentioned as being caused by water leaking into the vehicle, which can be considered an unintended consequence rather than a result of poor decision-making [130137]. |
| Capability (Incompetence/Accidental) |
accidental |
(a) The software failure incident related to development incompetence is not explicitly mentioned in the provided article [130137].
(b) The software failure incident related to an accidental factor is highlighted in the article. The National Highway Traffic Safety Administration (NHTSA) reported that water damage is to blame for the electronic parking brake problems in over 1.3 million Jeep Cherokee SUVs. The NHTSA mentioned that the EPB module is damaged by water leaking into the vehicle, leading to the inadvertent activation of the electronic parking brake, causing a stalling condition that brings the vehicle to a stop. This accidental factor of water damage affecting the EPB module is a key contributor to the software failure incident in this case [130137]. |
| Duration |
temporary |
The software failure incident related to the electronic parking brake problems in the Jeep Cherokee SUVs can be categorized as a temporary failure. The incident was attributed to water damage affecting the EPB module, leading to the brakes inadvertently activating while the vehicle is in motion. This issue is not a permanent failure as it is specifically linked to the presence of water leaking into the vehicle, causing the malfunction. The temporary nature of the failure is evident from the fact that the problem arises under certain circumstances, such as water damage, rather than being a constant issue present in all circumstances [130137]. |
| Behaviour |
crash, omission, value, other |
(a) crash: The software failure incident in the Jeep Cherokee SUVs was related to the electronic parking brakes inadvertently activating while the vehicle is in motion, causing a stalling condition and bringing the vehicle to a stop [130137].
(b) omission: The software failure incident in the Jeep Cherokee SUVs resulted in the electronic parking brakes omitting to function correctly, leading to unintended activation while the vehicle was in motion [130137].
(c) timing: The software failure incident in the Jeep Cherokee SUVs did not specifically mention any timing-related issues where the system performed its intended functions too late or too early [130137].
(d) value: The software failure incident in the Jeep Cherokee SUVs involved the electronic parking brake module being damaged by water leaking into the vehicle, leading to incorrect activation of the parking brakes and causing a stalling condition [130137].
(e) byzantine: The software failure incident in the Jeep Cherokee SUVs did not exhibit behaviors of inconsistent responses or interactions that would classify it as a byzantine failure [130137].
(f) other: The software failure incident in the Jeep Cherokee SUVs could be classified as a safety-related issue where the system's failure to function correctly posed a risk to the vehicle and its occupants [130137]. |
