Braking Safety Concern In 2025 Nissan And Infiniti Vehicles

Posted on by

Nissan has issued a recall for certain 2025 model year Murano, Pathfinder, and Infiniti QX60 vehicles due to a potential braking safety issue. The problem affects the front brake caliper assemblies, which may have reduced strength and could break, leading to reduced braking performance.

The issue was discovered in January 2025 during a routine production brake test on a 2025 Nissan Pathfinder. A technician reported a failure of the front right-hand brake caliper assembly, prompting Nissan to quarantine the defective part and launch an investigation. Further analysis revealed that the suspect brake caliper had been produced with a common supplier production lot code (51A), which was found to have an inadvertent modification to an internal parameter setting. This modification reduced the material’s strength, making it more prone to failure.

The supplier’s investigation confirmed that a total of 3,115 caliper castings were produced in the affected lot and shipped to Nissan for assembly into vehicles. Through traceability records, Nissan identified 2,341 vehicles that may have received a potentially affected brake caliper. Of these vehicles, 711 were held for inspection, while 200 had been exported and 1,430 had previously been shipped to the US.

According to Nissan, if one or both of the front brake calipers fail, it can result in reduced braking performance and may not comply with certain performance requirements of Federal Motor Vehicle Safety Standard (FMVSS) 135. This could increase the risk of a crash, particularly if drivers are unable to stop their vehicles in time. Affected customers may notice uneven braking performance, and the “Low Brake Fluid” warning light may illuminate in certain cases.

To address the issue, Nissan will be recalling affected vehicles and asking owners to return to their dealerships for an inspection and replacement of the front brake caliper assemblies as necessary. Owner notification letters are expected to be mailed on May 9, 2025. The recall is identified as Nissan’s numbers PD137 and PD138, and the NHTSA campaign number is 25V-173. This issue highlights the importance of rigorous testing and quality control measures in ensuring the safety of vehicles on the road.

Mazda will soon be reaching out to the owners of specific 2016-2023 Mazda MX-5 Miata vehicles due to a software issue affecting the airbag control module. This problem, first identified in April 2023, stems from a calibration error that may result in the front airbags deploying with excessive force during a crash. As a consequence, these vehicles fail to meet the Federal Motor Vehicle Safety Standards (FMVSS) for Occupant Crash Protection, potentially endangering the safety of both drivers and passengers.

Mazda became aware of the issue during the development of new airbag sensors for future models. During this process, engineers uncovered a misconfiguration in the calibration tool used to set up the airbag control modules. This discovery prompted Mazda to reevaluate and reassess the settings in control modules from earlier vehicle models. Through a series of rigorous simulation tests, Mazda found that the collision detection sensitivity in the 2016-2023 MX-5 Miata models could lead to improper airbag deployments that do not comply with safety standards.

The problem particularly arises during minor collisions, where the airbags may deploy with a force higher than intended. This excessive force poses an increased risk of injury to vehicle occupants, especially in situations where airbag deployment should be less aggressive. Although the issue seems isolated to the MX-5 Miata, Mazda has taken steps to conduct similar tests across other vehicle models to ensure that the problem does not affect a broader range of vehicles.

To resolve this issue, Mazda dealers will perform a software update on the Sophisticated Air Bag Sensor (SAS) control module of the affected vehicles. This update is designed to re-calibrate the airbag deployment system to meet FMVSS 208 standards, ensuring that airbags deploy at appropriate force levels in the event of a collision. Mazda has scheduled owner notification letters to be mailed starting November 17, 2024, alerting owners to the recall and the necessary repairs.

Posted on by

Ford Motor Company (Ford) have discovered a defect affecting certain 2021-2022 Bronco, F-150, Edge, Explorer, Lincoln Nautilus, and Lincoln Aviator vehicles equipped with either a 2.7L or 3.0L Nano EcoBoost engine. The engine intake valves may break while driving, which can result in engine failure and a loss of drive power.

The following vehicle models are affected by this recall:

2021-2022 Ford Bronco
2021-2022 Ford Edge
2021-2022 Ford Explorer
2021-2022 Ford F-150
2021-2022 Lincoln Aviator
2021-2022 Ford Bronco

In January 2022, an investigation was opened into certain 2021 Lincoln Aviator and Nautilus vehicles equipped with 2.7L and 3.0L Nano EcoBoost engines after 22 instances of engine failure were reported within three months of service. The issue involved left-hand engine intake valve fractures, which led to catastrophic engine damage and Loss of Motive Power (LOMP). A tear down analysis confirmed intake valve fractures in 251 engines from warranty repairs.

Ford traced the problem to intake valves exceeding the hardness specification due to faulty grinding processes by the supplier. The intake valve material was changed for vehicles produced after October 31, 2021, to improve robustness.

On May 5, 2022, Ford opened an internal investigation into early intake valve fractures, and on May 27, 2022, the National Highway Traffic Safety Administration (NHTSA) began its own investigation after receiving reports from Ford Bronco owners. NHTSA expanded the scope of the investigation in July 2022.

On August 16, 2024, Ford’s Field Review Committee approved a field action to address the issue.

Dealers will perform an engine cycle test and replace the engine as necessary. Owner notification letters are expected to be mailed October 7, 2024. Ford’s number for this recall is 24S55 and the NHTSA campaign number is 24V-635.

Cadillac Lyriq Defective Brake Performance

Posted on by

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.
