A potential safety issue has been identified in certain 2023-2024 Cadillac Lyriq all-wheel-drive vehicles. This defect could affect the vehicle’s braking performance, posing a risk to drivers and passengers.

The investigation into this issue began in May 2024, when General Motors (GM) received reports of two minor accidents allegedly caused by a sudden loss of braking. Both incidents were suspected to be linked to a software problem within the vehicles’ Anti-lock Braking System (ABS). In addition to these accidents, GM was also alerted to a separate field complaint that, while not resulting in an accident, seemed potentially related to the same problem.

To get to the bottom of the issue, GM’s investigation team gathered and analyzed field data from various sources. Despite the initial reports, they found no additional cases that could be connected to this defect. However, through careful analysis, they determined that the problem could indeed occur, but only in extremely rare situations. Specifically, the issue arises when a false ABS event occurs on a dry road at speeds under 25 mph. During this event, if a particular series of wheel movements takes place, the ABS system might continue to release brake pressure in the vehicle’s service brake system, even when it shouldn’t.

Fortunately, GM has confirmed that no injuries or fatalities have been associated with this condition. However, given the potential risk, GM’s Safety Field Action Decision Authority (SFADA) decided in August 2024 to issue a safety recall for the affected vehicles.

The defect report explains that under certain rare braking conditions on dry surfaces at speeds below 25 mph, the ABS may become overly sensitive. If the ABS falsely activates and a specific sequence of wheel movements occurs, the system might continue to release brake pressure, which can significantly reduce the effectiveness of the service brakes. This could lead to a reduction in stopping performance or even cause the brakes to become inoperative, thereby increasing the risk of a crash.

To address this issue, GM has made an update to the electronic brake control module software. This update can be installed either through an over-the-air (OTA) update or by visiting a GM dealership. If you own one of the affected vehicles, GM urges you to take action as soon as possible. The recall number for this issue is N242453471, and the National Highway Traffic Safety Administration (NHTSA) campaign number is 24V-598.

A recent safety concern has emerged for a small number of 2021 and 2024 Nissan Titan vehicles due to a potential issue with their Air Bag Control Unit (ACU). This problem, if left unaddressed, could increase the risk of injury to occupants in the event of a crash.

In May 2024, Nissan was alerted by their airbag supplier about a production error that involved a missing spacer between the ACU fastener and the base plate. This spacer plays a critical role in ensuring that the ACU is properly secured. Without it, there is a risk that the fastener could interfere with the vehicle’s floor pan, leading to the fastener becoming loose. If this occurs, the airbag may deploy late or not at all, which could significantly increase the risk of injury during a crash.

Upon learning about the problem, Nissan and the supplier conducted a thorough audit. They discovered that 531 affected parts had been shipped to Nissan’s Canton, MS Plant. Fortunately, 528 of these parts were identified and quarantined before they could be installed in vehicles. However, three parts had already been installed in 2024 Nissan Titan vehicles that had been shipped.

In June 2024, the supplier identified additional affected parts included in a service part kit, of which 41 were shipped to Nissan. Nissan was able to quarantine and scrap 37 of these parts, but four had already been installed in 2021 Nissan Titan vehicles during repairs.

On July 19, 2024, after further assessment, Nissan confirmed that the absence of the spacer could indeed cause interference with the floor pan, potentially leading to loose fasteners and compromised airbag deployment.

As a result of these findings, Nissan decided on July 29, 2024, to initiate a Voluntary Safety Recall for the seven affected vehicles—three from the 2024 model year and four from the 2021 model year. While there have been no reports of accidents or injuries related to this issue, Nissan is taking precautionary measures to ensure the safety of its customers.

Nissan will address the issue by replacing the ACU in the affected vehicles. Owners of these vehicles will receive notification letters starting September 19, 2024. The recall number assigned by Nissan is PD120, and the corresponding National Highway Traffic Safety Administration (NHTSA) campaign number is 24V-580.

Although the number of vehicles affected is small, this recall is a critical step to ensure the safety of Nissan Titan drivers and passengers. If you own a 2021 or 2024 Nissan Titan, keep an eye out for the notification letter and get the the necessary repairs.

The secondary steering torque sensor may not be properly calibrated on certain 2018-2023 Ford Mustang, 2018-2020 Ford F-150, 2018-2021 Ford Expedition, and 2018-2021 Lincoln Navigator vehicles. These vehicles are equipped with electronic power assist steering (EPAS) gears, which were installed as replacement service parts and are now found to have potential calibration issues.

This issue came to light when Ford’s Critical Concern Review Group (CCRG) was alerted by the supplier about an assembly problem affecting certain steering gears. To thoroughly understand the extent of this problem, Ford’s CCRG conducted a detailed review that included examining supplier maintenance records, warranty reports, and vehicle testing data. The findings prompted Ford’s Field Review Committee to decide on issuing a recall to address the defect.

The defect report indicates that the electronic Power Assist Steering (EPAS) gears, which were sold as service parts, may have an incorrectly calibrated secondary digital torque sensor in the steering gear. Specifically, the polarity of this sensor may be inverted. If the primary steering torque sensor fails or develops a fault, and the secondary digital torque sensor’s polarity is inverted, the steering wheel could start oscillating without warning. This means the steering wheel might alternate between clockwise and counterclockwise movements when the driver attempts to steer, leading to unintended steering assist from the electronic power steering gear.

This oscillation poses a significant safety risk as it can make steering unpredictable and difficult to control, potentially leading to accidents. Recognizing the severity of this issue, Ford has taken measures to address it.

Ford dealers will update the Power Steering Control Module (PSCM) software in the affected vehicles to correct the calibration issue. This update is intended to ensure the proper functioning of the secondary torque sensor, thereby preventing the unintended steering oscillation.

Owner notification letters were mailed on August 5, 2024, to inform vehicle owners about the recall and the necessary steps to have their vehicles repaired. Ford has assigned this recall the number 24S45, and it is also registered under the National Highway Traffic Safety Administration (NHTSA) campaign number 24E-055.

General Motors (GM) has announced a safety recall affecting a small number of its 2024 Cadillac XT5 vehicles. This recall addresses a potential defect with the driver front airbag. This defect may pose a risk to vehicle safety.

The issue was identified when GM’s airbag module supplier observed a tear in the airbag cushion during a routine lot-acceptance test. This incident, which occurred in February 2024, prompted a thorough investigation by GM. The supplier was able to isolate the affected batch and performed additional tests on these airbags across various temperature settings to assess their reliability and safety.

The tests revealed that the airbag cushions could tear during deployment due to a recent design change in the airbag modules. Following these findings, GM’s Safety Field Action Decision Authority (SFADA) made the decision to issue a recall for all vehicles equipped with airbag modules from the affected production lot, manufactured the day before the problematic batch.

It is important for consumers to understand that a tear in the airbag cushion during deployment can significantly impair the airbag’s performance in the event of a crash, thereby increasing the risk of injury to the occupants.

To address this safety concern, GM is taking proactive steps. The company will replace the driver’s front airbag module at no cost to vehicle owners. GM plans to begin notifying affected Cadillac XT5 owners through formal letters, which are scheduled to be sent out on June 17, 2024. The recall has been officially recorded under GM’s number N232439241 and the National Highway Traffic Safety Administration (NHTSA) campaign number 24V-311. GM has confirmed that there have been no field incidents or injuries reported in relation to this defect.

In a recent development, owners of 2019 Jaguar I-Pace vehicles are being urged to take immediate action due to a critical safety concern that could potentially lead to vehicle fires.

However, as with any technological advancement, occasional glitches and malfunctions can arise, potentially jeopardizing the safety of drivers and passengers alike. Such is the case with the “phantom braking” issue that has plagued certain 2023 Chevrolet Colorado and GMC Canyon trucks.

The issue came to light in September 2023, when reports of unexpected automatic emergency braking (AEB) incidents surfaced in General Motors (GM) vehicles in China. GM initiated an investigation through its Speak Up For Safety (SUFS) program, aiming to identify the root cause of the problem and implement appropriate corrective measures.

Upon investigation, it was discovered that the faulty behavior stemmed from the Front Camera Module (FCM) system, a crucial component responsible for detecting obstacles and triggering AEB when necessary. Under certain conditions, the FCM’s software exhibited erroneous detection of obstacles, resulting in unwarranted activation of the AEB system. This phenomenon, referred to as “phantom braking,” poses a significant safety risk, potentially leading to accidents and injuries.

GM, in collaboration with its supplier, conducted rigorous testing and analysis to pinpoint the underlying cause of the malfunction. This involved examination of field data from various sources, including different versions of the FCM software, vehicles produced in different periods, and reports from both the U.S. and China.

A total of 234 field complaints in the U.S. were potentially linked to the phantom braking issue. Among these incidents, four resulted in accidents, with three causing minor injuries to occupants. GM’s Safety Field Action Decision Authority (SFADA) made the decision to initiate a safety recall in February 2024.

The recall, identified by GM as A232424660 and by the National Highway Traffic Safety Administration (NHTSA) as campaign number 24V-133, involves a corrective measure aimed at rectifying the software glitch in the FCM. Authorized dealerships will apply updates to the FCM software, effectively addressing the root cause of the phantom braking issue and restoring the intended functionality of the AEB system.

In conclusion, while the emergence of advanced driver assistance systems has undoubtedly enhanced automotive safety, incidents such as the phantom braking issue serve as a stark reminder of the importance of vigilance and proactive intervention. Through swift action and collaboration between manufacturers, suppliers, and regulatory agencies, the automotive industry can continue to push the boundaries of safety innovation, ensuring that drivers can enjoy the benefits of technology without compromising their well-being on the road.

Chrysler (FCA) will be contacting the owners of certain 2021-2024 Jeep Wrangler and 2022-2024 Jeep Grand Cherokee over a failure to comply with Federal Motor Vehicle Safety Standards (FMVSS) related to windshield defrosting and defogging systems. Owners of affected vehicles are urged to take immediate action to rectify this potentially hazardous issue.

In June 2023, FCA Technical Safety and Regulatory Compliance (TSRC) organization received reports indicating a potential malfunction in the windshield defrost system of certain 2021-2024 Jeep Wrangler Plug In Hybrid Electric Vehicles (PHEVs) and 2022-2024 Jeep Grand Cherokee PHEVs. This issue raised concerns about the vehicles’ compliance with FMVSS.

An investigation conducted by FCA determined that a subset of these vehicles may have been built with incorrectly programmed hybrid control processor (HCP) software. This flaw could result in the disabling of the windshield defrost system under specific conditions. The affected period for the Jeep Wrangler spans from September 2, 2020, to August 24, 2023, while for the Jeep Grand Cherokee, it extends from July 23, 2021, to December 5, 2023.

A disabled windshield defrost system poses a significant safety risk, as it can impair outward visibility during critical driving conditions, potentially leading to accidents. In response to this safety concern, FCA has initiated a voluntary safety recall of the affected vehicles.

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.
