Fiat Spider Airbag Could Deploy With Excessive Force

Posted on by

Chrysler (FCA US, LLC) has identified a software error in the airbag control module of certain 2017-2020 Fiat/Abarth 124 Spider vehicles. This issue can cause the airbags to deploy with excessive force during a crash, which poses a safety risk. As a result, these vehicles do not comply with the Federal Motor Vehicle Safety Standards (FMVSS) for occupant crash protection, specifically FMVSS No. 208, which governs crash protection and performance requirements for automotive airbags.

The problem came to light in July 2024, when Mazda Motor Corporation, a partner in the development of these vehicles, notified Stellantis Europe S.p.A. about a potential issue with the airbag control module. Mazda discovered this error during the development of new airbag sensors for upcoming vehicle models. As part of the research and testing process for these sensors, engineers identified a misconfiguration in the calibration tool used to program airbag control modules.

This discovery prompted Mazda to take a closer look at the settings of airbag control modules in previous models, including the 2016-2023 MX-5 Miata. During extensive simulation tests, Mazda engineers uncovered a potential flaw in the collision detection sensitivity of the airbag system. This flaw could cause airbags in these models to deploy improperly, failing to meet the safety standards designed to protect passengers from serious injury. The main concern is that the system might trigger the deployment of the dual-stage front airbag rather than the single-stage deployment that is appropriate for certain types of collisions. This misconfiguration increases the risk of neck injuries during a frontal crash.

FMVSS No. 208 requires that vehicles meet specific performance standards related to neck injury prevention during a 26 km/h frontal impact. The dual-stage airbag deployment in the affected Fiat/Abarth 124 Spider vehicles increases the force of the airbag during deployment, potentially leading to a higher risk of neck injuries, which would prevent the vehicles from meeting these safety requirements.

The issue is not related to a defective part, but rather a design oversight in the programming of the airbag control module. The voltage specifications for the accelerometer, a key component of the system that detects a crash and triggers the airbags, were incorrectly set. This misconfiguration leads to improper airbag deployment, which could result in the failure to meet safety regulations.

To remedy this issue, Chrysler will reprogram the airbag control module in all affected vehicles with the correct specifications. This software update will ensure that the airbags deploy at the appropriate force in the event of a crash, reducing the risk of injury and bringing the vehicles into compliance with federal safety standards.

Chrysler plans to begin notifying vehicle owners about the recall on November 7, 2024. Once notified, owners will be instructed to bring their vehicles to authorized dealerships for the airbag control module to be reprogrammed at no cost. In the meantime, Chrysler has assigned the recall number A3B to this issue, and the National Highway Traffic Safety Administration (NHTSA) has assigned it the campaign number 24V-694.

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.

Mazda’s recall number for this issue is 6924I, and the National Highway Traffic Safety Administration (NHTSA) has assigned campaign number 24V-695 to this recall.

Certain 2023-2024 GM Vehicles Fail to Meet FMVSS for Brake Systems

Posted on by

Certain 2023-2024 Cadillac, Chevrolet and GMC vehicles fail to meet the Federal Motor Vehicle Safety Standard (FMVSS) for light vehicle baking systems. The problem is, the driver may not receive an indicator of a loss of brake fluid before the level is below FMVSS 135’s requirement.

The FMVSS 135 requires that vehicles have a system in place to warn the driver when the brake fluid level drops to a certain point. This allows time for the problem to be addressed before it affects braking performance. However, in the affected vehicles, the brake fluid warning light may not illuminate in time to alert the driver before the fluid drops below the required level. This delay in the warning light could lead to reduced brake performance, increasing the risk of a crash.

The following vehicle models are affected by this problem:

2023-2024 Cadillac Escalade
2023-2024 Cadillac Escalade ESV
2023 Chevrolet Silverado 1500
2023-2024 Chevrolet Suburban 1500
2023-2024 Chevrolet Tahoe
2023 GMC Sierra 1500
2023-2024 GMC Yukon
2023-2024 GMC Yukon XL

GM became aware of this issue through its Speak Up for Safety (SUFS) program. A GM engineer noticed during a brake fluid leak test that the required warning light (referred to as the BRAKE telltale) did not illuminate as expected. This led GM to launch a full investigation. The issue was traced to a mismatch in the software and calibrations of the Electronic Brake Control Module (eBCM). This software mismatch was preventing the vehicle from detecting a brake fluid leak in time to alert the driver. Fortunately, GM has not received any reports of crashes or injuries related to this issue, but the potential for delayed notification of a brake fluid leak poses a safety concern.

In the event of a brake fluid leak, the vehicle’s brake pedal could become less responsive before the warning light appears. This degraded brake performance, combined with the delayed warning, could increase the likelihood of a crash. However, GM has confirmed that even in these circumstances, the vehicles still meet federal stopping distance requirements, meaning they should still be able to stop within the legally required distance.

Owners of affected vehicles will be notified by mail starting October 28, 2024. GM will provide a software update for the eBCM that will correct the issue. This update can be done remotely through an over-the-air (OTA) update or by visiting a dealership. If you own one of these vehicles, you do not need to take immediate action unless you notice any issues with your brakes. The recall is precautionary, and the software update will ensure that your vehicle meets all federal safety standards moving forward.

GM’s recall number for this issue is N242447990, and the National Highway Traffic Safety Administration (NHTSA) campaign number is 24V-674.

Unexpected ABS Activation In 2024 Acura ZDX All-Wheel Drive Vehicles

Posted on by

In a concerning development for Acura ZDX All-Wheel Drive owners, a potentially dangerous issue has been identified within certain 2024 models. The problem, rooted in the vehicle’s anti-lock brake system (ABS), could lead to unexpected activation of the ABS, causing a release of brake pressure that significantly diminishes braking performance. This defect poses an increased risk of accidents, particularly during specific low-speed braking events.

The problem first came to light in July 2024 when Honda, Acura’s parent company, was notified by General Motors (GM) about the issue. GM had received reports of two minor accidents, both allegedly linked to a sudden loss of braking, which were suspected to be caused by a software glitch in the ABS. In addition to these accidents, GM also reported a field complaint regarding the issue, though no accident had occurred in that instance.

Honda quickly launched an investigation into the matter. Upon closer examination, it was discovered that the issue was indeed related to a defect in the anti-lock brake system. Specifically, during certain braking events at speeds below 25 mph on dry surfaces, the ABS may activate with undue sensitivity. If this occurs and a specific sequence of wheel movements follows, the ABS will continue to release brake pressure in the service brake system. The result is a dramatic reduction in stopping performance, or in some cases, a complete failure of the brakes, greatly increasing the risk of a crash.

After confirming the defect, Honda determined that it posed a significant safety risk and initiated a safety recall. The company has emphasized that, as of now, no warranty claims, field reports, or incidents involving injuries or crashes related to this defect have been reported in Acura vehicles.

Affected vehicle owners will be notified of the recall and instructed to perform an iN VIN status inquiry to verify if their vehicle is eligible for the update.
