The Steering Knuckle And Strut May Be Loose In Certain 2023 Ford Explorer Vehicles

Posted on by

In a recent announcement, Ford has highlighted a critical concern affecting a specific subset of its 2023 Ford Explorer vehicles. The issue revolves around the right-front lower fastener connecting the steering knuckle and strut, which may either be loose or missing altogether. This problem can have significant repercussions on the vehicle’s performance and safety.

A loose or missing connection between the knuckle and strut can lead to improper tire alignment, potentially causing steering pulls or requiring increased steering effort. Moreover, the proximity of the brake hose to the tire in this compromised setup poses an additional risk. If the hose comes into contact with the tire, it may sustain damage resulting in a brake fluid leak, ultimately leading to a loss of braking ability. These circumstances significantly elevate the likelihood of a crash, underscoring the severity of the situation.

Upon receiving a report of a missing fastener,Ford’s Critical Concern Review Group (CCRG) initiated an investigation at the beginning of January 2024. The Plant Vehicle Team (PVT) at the Assembly Plant promptly identified the issue during a routine warranty claim review. Further analysis revealed that the primary double spindle fixture tool responsible for securing the right front knuckle-to-strut fasteners was offline for repairs during a specific period. This temporary setback affected a limited number of vehicles, with Ford confirming that out of 121 Explorer rotations, only one vehicle was found to have a missing fastener. Nonetheless, the company is taking proactive steps to address the concern.

While Ford has not identified any vehicle owner questionnaires (VOQs) related to this condition, it’s crucial for affected vehicle owners to remain vigilant. Signs of potential issues include a visually detectable tire leaning inward at the top or changes in steering effort or pull. Additionally, if there are any indications of tire contact with the strut or spring seat, such as abrasion damage or a burning smell, prompt action is necessary.

In response to this concern, Ford has announced a field action to have the affected vehicles inspected. Dealers will thoroughly examine the fasteners and take appropriate measures, such as tightening or installing them as needed, to rectify the issue. Affected vehicle owners can reference Ford’s recall number 24S04 and the corresponding NHTSA campaign number 24V-091 for further information and to schedule inspections.

Hyundai Kona Potential Engine Compartment Fire From Short Circuit

Posted on by

Hyundai Motor America (Hyundai) is initiating a recall for certain 2024 Kona models due to a potential risk of electrical short circuiting. This issue arises from the possibility of the battery cables rubbing against the engine control module bracket.

These vehicles are equipped with a 12-volt positive battery cable that could suffer damage during frontal collisions, leading to contact with the engine control module (ECM) bracket. This contact increases the likelihood of an electrical short, which could result in a fire in the engine compartment post-collision. Signs of this problem include smoke or a burning smell emanating from the engine area.

The issue first came to Hyundai’s attention in November 2023, following a report by the Insurance Institute for Highway Safety (IIHS) about an engine compartment fire in a 2024 Hyundai Kona 1.6T-GDI AWD during a crash test. The IIHS observed smoke and flames emerging from the engine area shortly after the test. Their preliminary assessment indicated a short circuit in the ECM, which led to repeated reignitions. The situation was resolved after disconnecting the auxiliary battery. This incident prompted NASO to launch a new investigation.

A joint examination by NASO, HMC, HATCI, and IIHS revealed damage to the alternator and 12-volt positive power wiring beneath the ECM, with exposed copper cores. The ECM bracket was found pressing against the 12-volt positive battery cable, believed to have shifted during the crash and caused the electrical short leading to the fires.

In response, Hyundai conducted crash tests in December with newly designed sheathing to protect the 12-volt positive wiring from shorting due to ECM bracket contact. These tests were successful, showing no damage or electrical shorting. Consequently, HMA’s NASO decided to recall the affected Kona vehicles.

To date, there have been no reported crashes, injuries, or deaths related to this issue, except for the single fire incident during the IIHS test. Hyundai is unaware of any field incidents. Vehicle owners will be notified to return their vehicles to Hyundai dealers for the installation of protective sheathing over the wiring. The recall is designated as number 252, with NHTSA campaign number 23V-900.

2020-2023 Ford Mustang No Low Brake Fluid Warning

Posted on by

brake light warningSome Mustang cars made between 2020 and 2023 have a problem with their brake fluid level sensor. This sensor doesn’t activate a warning light when the brake fluid is low. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standards for light vehicle brake systems.

Ford became aware of the problem in August 2023 when an issue pertaining to 2020-2023 model year Mustang brake fluid level warning systems was brought into Ford’s Critical Concern Review Group (CCRG) for review. They discovered that the problem lies with the Body Control Module (BCM), a part that manages the brake fluid sensor. This BCM should turn on the brake warning light if there’s a problem. In Mustangs made from 2018 to 2023, the brake fluid sensor is directly connected to the BCM. However, in the 2020 Mustang, they switched to a different BCM design, called “Gen1m,” which incorrectly looks for a message from the brake fluid sensor over a network (CAN) instead of the direct connection.

After investigating, Ford confirmed that this problem only affects Mustangs from 2020 to 2023. They also verified that the 2024 Mustang doesn’t have this issue because the brake system and BCM are set up correctly. The Brake Development team tested Mustangs from 2019 to 2024 and found that the 2020 to 2023 models fail to meet the requirements for warning about low brake fluid. However, these vehicles meet all other brake system warning lamp requirements.

Ford initially didn’t run certification tests on the 2020 to 2023 Mustangs because they thought the brake system was the same as in the 2018 model. They didn’t know that the BCM was incorrectly configured to use a network message.

As of September 12, 2023, Ford received 123 warranty claims related to a brake fluid loss on these vehicles, but there were no reports of the brake fluid level sensor not working.

To fix the problem, Ford dealers will update the software in the body control module. They plan to send out initial letters in December 2023 to notify owners about the safety issue and will send second letters when the solution is available. This recall is identified by Ford as number 23C35, and the NHTSA campaign number is 23V-727.

Ford Mustang Mach E Battery Contactor Could Overheat

Posted on by

Certain 2021-2022 Ford Mustang Mach-E cars might face a power problem due to an overheated high voltage battery contactor, potentially leading to an increased risk of accidents.

In June 2022, Ford’s Field Review Committee (FRC) gave the green light to a Field Service Action (FSA) named 22S41, specifically designed to tackle concerns regarding the overheating of the high voltage battery main contactor in select 2021-2022 Mustang Mach-E vehicles. To fix this issue, dealers updated the software for the Secondary On-Board Diagnostic Control Module (SOBDMC) and the Battery Energy Control Module (BECM). The enhanced SOBDMC software keeps an eye on the contactor’s temperature and smartly reduces the battery’s power output to prevent further damage. Meanwhile, the upgraded BECM software checks the contactor’s resistance to identify any damage, then it generates a diagnostic trouble code (DTC) and lowers the vehicle’s power to avoid more harm.

At the time of approving this FSA, Ford’s Critical Concern Review Group (CCRG) and Electrical Propulsion Engineering (EPE) teams found the software updates for BECM and SOBDMC to be a suitable way to minimize the safety risks linked to power loss. The software update, by monitoring contactor resistance, warns customers if the resistance exceeds a certain limit. Alongside the warning, the software reduces power to prevent further contactor damage and the associated power loss risk. Even with the reduced power, customers can safely accelerate to highway speeds. This approach was also reviewed with the National Highway Traffic Safety Administration (NHTSA).

In June 2022, Ford Motor Company decided to issue a safety recall (NHTSA Recall 22V-412) for 48,924 model year 2021-2022 Ford Mustang Mach-E vehicles produced between May 27, 2020, and May 24, 2022. This recall was prompted by concerns about high voltage battery contactors overheating, primarily due to direct current (DC) fast-charging and repeated full-throttle pedal events. This overheating could lead to arcing or deformation of the electrical contact surfaces. If this occurs, the contactor could either remain open or get welded shut. An overheated contactor that opens while driving may lead to an immediate loss of power without re-engagement.

Following consumer complaints, the Office of Defects Investigation (ODI) initiated a Recall Query (RQ) for 2021-2022 Ford Mach-E vehicles included in Recall 22V-412. These vehicles had previously received a remedy involving a Secondary On-Board Diagnostic Control Module (SOBDMC) software update to monitor contactor temperature and reduce battery power to protect the contactor, as well as a Battery Energy Control Module (BECM) software update to monitor contactor resistance and reduce vehicle power in case of an overheated contactor.

To address this issue, dealers will replace the high voltage battery junction box. This recall is identified by Ford as 23S56, and the corresponding NHTSA campaign number is 22V-687. Vehicles included in this recall that were previously repaired under recall 22V-412 will need to have the new remedy completed.

Nissan Ariya Inverter Software Problem

Posted on by

Nissan North America, Inc. (Nissan) is reaching out to the owners of certain 2023 Ariya vehicles due to an issue with the inverter software. This problem may trigger the inverter to detect a short circuit, causing a shutdown of the EV system and a loss of drive power.

The Discovery of the Problem:

Nissan first became aware of this issue during a production trial involving an Ariya vehicle in January 2022. In this trial, the electric motor abruptly shut off shortly after the vehicle began moving at low speed. A diagnostic trouble code (DTC) revealed a short circuit inside the motor, although no actual damage to the motor or its components was observed. A deeper investigation into the problem found that in some rare instances, conductive fibers generated during the operation from the slip ring in the motor could lead to a momentary short circuit between the electrodes.

Understanding the Problem:

Nissan Ariya dashAccording to the defect report, the root cause of the issue lies in conductive fibrous shavings from the drive motors’ slip ring assembly. These shavings can occasionally cause a momentary short circuit between the two slip rings. When this occurs, the fibrous shavings are instantaneously burned out, causing no harm to any vehicle components. However, when the inverter detects a momentary over-current due to the short circuit, it reduces motor torque to protect the internal components of the controller. This leads to a loss of drive power, and an “EV System Off” message is displayed on the dashboard to alert the driver.

In the event of this issue occurring, the torque to the driven wheels is cut off. This continues until the fail-safe mode is released, which requires turning the vehicle off and then back on. An unexpected loss of motive power while driving at high speeds could potentially increase the risk of an accident.

Nissan’s Solution:

To address this safety concern, Nissan dealers will reprogram the inverter software to enhance the fail-safe protocols. This proactive measure aims to prevent such short circuits from impacting the driving experience and maintaining safety for the driver.

Recall Details:

Nissan has designated this recall as R23C6 and the National Highway Traffic Safety Administration (NHTSA) has assigned the campaign number 23V-657 to this recall.
