Approximately 1,300 Toyota Prius vehicles are being recalled in Singapore due to a defect in the electric rear door lock system that could potentially allow doors to open while the car is in motion.
Borneo Motors, the authorised distributor for Toyota in Singapore, explained that water entering the door opener switch could cause a short circuit, triggering the rear doors to open unexpectedly. “If the seal performance of the switch is reduced from thermal cycling and water enters—such as from car washes—closing the door with force may temporarily allow water in. If detergent is present, this can lead to a short circuit activating the switch,” the company said.
Affected owners are being notified by mail. Repairs will involve modifying the left and right rear door switch circuits to prevent activation even if a short occurs. Borneo Motors confirmed that the rectification work is free of charge and can be completed within a single day.
The recall follows a similar action in January for nearly 20,000 Prius hybrid cars in the United States and Canada over comparable safety issues.
“Borneo Motors Singapore remains committed to maintaining the highest standards of safety, quality and transparency for our customers,” the company added, emphasising its dedication to addressing the issue promptly.
