August 16, 2024 (press release) –
- Approximately 5,000 ZDX A-Spec AWD and ZDX Type S vehicles in the U.S. affected by software issue that can cause loss of braking below 25 mph
- Free repairs can be completed via over-the-air software update available today, Aug. 16, with no dealer visit required, or with dealer assistance
- No related crashes or injuries in Acura vehicles have been reported
- Recall only applies to AWD vehicles
Acura will voluntarily recall approximately 5,000 ZDX all-wheel-drive (AWD) vehicles in the U.S. to update the Electronic Brake Control Module (EBCM) software, free of charge. The over-the-air update will be sent to all vehicles today. The recall affects the 2024 ZDX A-Spec AWD and 2024 ZDX Type S.
The update will address an issue that can arise when applying the brakes below 25 mph, on a flat, smooth, dry surface, where the vehicle may exhibit overly sensitive anti-lock braking system (ABS) control. In these conditions, if the ABS falsely activates and a specific sequence of wheel movements occur, the vehicle's ABS system will continue to release braking pressure in the vehicle's brake system. Stopping performance can be reduced or the brakes can become inoperable, increasing the risk of a crash.
ZDX owners will be prompted to install the update through a notification on the center touchscreen, after driving the vehicle and shifting to Park. Owners can also choose to install the update later by navigating to Settings, then Updates & History. To receive the over-the-air-update, the vehicle must already be enrolled in OnStar, and all required terms and conditions accepted.
The update may take up to 5 minutes. During this time, the vehicle will not be operable, and features like door locks, windows and warning chimes may not work; locked doors may not unlock using the power switch or remote fob.
If an owner needs assistance with the update process, they can visit their Acura dealer to perform the software update.
Acura is announcing this recall to encourage owners of affected vehicles to install the over-the-air update as soon as their vehicle prompts them to do so. The over-the-air update will be sent to all vehicles today, and mailed notification to owners of vehicles not already updated will occur in September. Owners of 2024 ZDX vehicles can also determine if their vehicles require repair by visiting http://www.recalls.acura.com or by calling (888) 234-2138.
