Recent developments in automotive safety have brought to light a significant issue with the 2021-2023 Volkswagen ID.4 models. These vehicles have been identified as having door handles that fall short of the required standards for water ingress protection. This defect poses a serious safety risk, as it can lead to malfunctions in the door lock system, causing doors to open unexpectedly.
The Central Safety Concern
The main safety hazard is the risk of doors opening spontaneously under high lateral forces, particularly at speeds below 9 mph (15 km/h). This can be dangerous for both the vehicle’s occupants and those outside, including pedestrians and nearby objects. The problem stems from water entering the printed circuit board within the door handle, leading to miscommunications with the door control unit.
Signs of the Malfunction
Drivers and passengers in the affected Volkswagen ID.4 models may notice an unusual clicking sound, similar to that of doors locking or unlocking, which can indicate the onset of this issue.
