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.

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

In recent years, advancements in automotive technology have led to increasingly sophisticated control systems within vehicles, aimed at enhancing performance, efficiency, and safety. However, with these advancements come the potential for unforeseen challenges and issues to arise.

One such challenge has been identified in certain models of Ford vehicles, specifically the 2021-2024 Ford Bronco Sport and the 2022-2023 Ford Maverick. The concern centers around the failure of the body control module (BCM) and powertrain control module (PCM) to accurately detect changes in the state of charge of the 12-volt battery. This oversight has significant implications, as it could result in a loss of drive power, thereby increasing the risk of accidents and compromising the safety of both drivers and passengers.

The issue first came to light in October 2023, when the National Highway Traffic Safety Administration’s Office of Defects Investigation (NHTSA ODI) initiated an inquiry following reports of loss of motive power (LOMP) and subsequent loss of 12-volt accessories in 2021 model year Bronco Sport vehicles. Upon receiving 29 potentially relevant Vehicle Owner Questionnaires (VOQs) from NHTSA, Ford’s Critical Concern Review Group (CCRG) promptly launched an investigation to delve deeper into the matter.

Subsequent testing and analysis revealed a fundamental flaw in the BCM and PCM calibrations, rendering them incapable of accurately detecting battery failure in the affected vehicles. This deficiency becomes particularly pronounced during instances where the alternator struggles to meet the electrical load demand or during Auto Stop-Start events. As a result, drivers may experience unexpected loss of drive power, posing a serious safety hazard.

In response to these findings, Ford’s Field Review Committee took decisive action and authorized a vehicle recall to address the underlying issue. Under the recall, authorized dealerships will undertake corrective measures by re-calibrating the BCM and PCM to ensure accurate monitoring of the 12-volt battery state of charge. The recall process is expected to commence soon, with owner notification letters slated to be mailed out on May 13, 2024.

However, the implications of this issue extend beyond the immediate safety concerns.
