2024 Mazda CX-90 Unexpected Brake Activation

On 2024-05-21 14:00:53

As an owner of a 2024 Mazda CX-90, you expect your vehicle to provide a safe and reliable driving experience. Unfortunately, certain models may be affected by an unexpected brake activation issue that could increase the risk of a rear-end accident.

The problem arises from the automatic braking system falsely detecting certain objects while driving, typically at low speeds (10-15MPH). This false detection can trigger the brakes to activate suddenly, which may lead to an unintended and potentially hazardous situation. The affected vehicles may display brake lights illuminating without any intentional driver input.


The Investigation and Remedy

Mazda first received reports of this issue in January 2023, prompting an investigation that continued throughout the year. In June 2023, Mazda implemented a mass production change to improve the vehicle control module (VCM) programming. However, further analysis revealed that this update was insufficient.


In August 2023, another software update was implemented to enhance detection logic. Although no field incidents were reported in the United States or territories, Mazda continued to monitor these markets closely.


Over the following months, Mazda analyzed field data and conducted testing on the VCM programming. In May 2024, a Quality Audit Committee meeting was held to review all available information, resulting in approval of a field action for certain MY2024 CX-90 vehicles.


The Solution

As part of this recall (Mazda's number: 6724E; NHTSA campaign number: 24V-347), dealers will reprogram the VCM with updated software at no cost to the owner. Notification letters are expected to be mailed on July 17, 2024.


As a CX-90 owner, it is essential to stay informed about this recall and take prompt action to have your vehicle's VCM reprogrammed. By doing so, you can ensure that your driving experience remains safe and worry-free. Remember, safety is paramount, and it is crucial to stay vigilant about any recall notifications or updates related to your vehicle. Stay informed, and enjoy the road ahead with confidence!
