The regulators and motors for the automatic windows have failed. The windows do not remain in the closed position causing the window to slide open. The front passenger window motor failed first and the driver’s window failed shortly after. Both regulators and motors were replaced by the dealer in April 2024. The back passenger side window failed in December 2024 and has not been replaced. If needed, the faulty mechanism could be provided for inspection. Failure of the closing mechanism for the windows means they can easily be opened from outside. A malicious person could break into the vehicle simply by sliding the window down. To my knowledge, no one has inspected the regulators or motors. Two other 2016 Hyundai Tucson owners I know have also had their window regulators and motors replaced. There was no warning to the automatic window failure.
