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. This notification is crucial for ensuring that all potentially affected vehicles, including those in new or used vehicle inventories, are addressed promptly.
To resolve this issue, Acura will be updating the electronic brake control module software. This update will be delivered either through an over-the-air (OTA) update or by visiting an Acura dealership. The update is designed to correct the sensitivity of the ABS, preventing the unexpected release of brake pressure and restoring normal braking function.
Acura has designated this recall with the internal number UJE, while the National Highway Traffic Safety Administration (NHTSA) has assigned it the campaign number 24VC-614.
Owners of the 2024 Acura ZDX All-Wheel Drive are urged to check whether their vehicle is affected by this recall. If you own one of these vehicles, it’s important to respond to the recall notice and ensure that the necessary software update is performed as soon as possible. This proactive step will help avoid the risks associated with the ABS defect and ensure your vehicle operates safely.
