Nissan Leaf Fire Risk From Quick Charging Battery

Posted on by

Nissan Leaf Smoking BatteryCertain 2019-2020 Nissan Leaf vehicles, specifically those equipped with quick charge ports for Level 3 charging using the CHAdeMO connector, are facing a potential issue where the battery could overheat during quick charging. This issue is serious, as it significantly raises the risk of a vehicle fire, which could lead to injury or property damage. The affected LEAF models were produced at Nissan’s Smyrna, Tennessee plant between August 29, 2018, and November 3, 2020. Nissan has identified this issue through their production records, confirming that it is limited to these specific Model Year 2019-2020 LEAF vehicles. Importantly, no other Nissan or INFINITI vehicles are known to be impacted by this defect, offering some reassurance to owners of other Nissan models.

Nissan is actively investigating the cause of this issue. Preliminary findings suggest that the problem stems from excessive lithium deposits forming inside the lithium-ion battery cells of these vehicles. These deposits increase the electrical resistance within the battery, which can cause fluctuations in the battery’s state of charge. This elevated resistance becomes particularly problematic during Level 3 quick charging, as it may result in the battery heating up more rapidly than intended. If the charging session continues under these conditions, the risk of a battery fire is significantly heightened, posing a serious safety concern.

Drivers may notice several warning signs during Level 3 charging that indicate something is wrong. These include the presence of smoke, unusual noises, interrupted charging sessions, or strange thermal odors emanating from the vehicle’s battery compartment. If any of these signs are observed, Nissan strongly advises stopping the charging process immediately and avoiding Level 3 charging altogether until the problem can be resolved.

Nissan is developing a solution for this issue in the form of a software update for the affected vehicles. Once available, this software update will be installed by dealers and is designed to correct the problem by managing the battery’s charging process more effectively. Nissan is taking steps to notify affected vehicle owners. Interim letters, alerting them to the safety risk, are expected to be mailed in October 2024. A second notice will follow once the software remedy is ready for deployment.

Until the fix is in place, Nissan advises owners to avoid using Level 3 quick charging stations and instead rely on slower charging methods, which do not present the same risk. For those affected, Nissan’s recall number is R24B2, and the corresponding NHTSA campaign number is 24V-700.

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.

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.
