2013 Lexus Gs 350 stuck wiper blades; danger level extremely high - may affect 2013-2015 and 2016-2020 Gs models when using the wipes in either automatic mode or manual speed selection they can become stuck in the rain in the up position blocking the windshield's view. This is extremely dangerous. Deemed a major flaw, the wiper blades can get stuck in any position while wiping. This occurs when the wiper blades are used and it is raining. This is very hard to replicate with windshield wiper fluid. To remedy the malfunction to survive in a life or death moment of limited visibility, the driver must quickly push the wiper lever activator up and down to reset it and or pushing in the automatic rain sensing function button. Also, when stopped at a stoplight and resuming acceleration, the rain sensor does not pick up rain at low, medium, or heavy rain and does not engage the wipers. Again, the user must re-engage the wiper system by turning it on and off again multiple times while driving over and over again, multiple times during a trip. The car should not be driven on highways at high speed during when raining or above 20 mph.
