One problem related to wiper has been reported for the 2019 Lexus GX460. The most recently reported issues are listed below.
When putting the vehicle in reverse the sideview mirrors automatically turn in and down per Lexus default. Problem is you cannot override the default to adjust them for a clear view to the rear, which means every time you back-up you have to adjust them. That creates 2 safety issues: first being sometime I am in the middle of the street trying to adjust the mirror to I can back-up, second if I don't I could possible damage or injure something or someone. I am a retied tractor-trailer operator, was also instructor qualified in the military, an accident investigator in the military, and have over a million miles under my belt. I say this so you understand if this was the military I would not let any of my soldiers operate this vehicle with the default Lexus has set the mirrors at. I have notified Lexus, but they are taking it as a dissatisfied customer instead of a safety issue and the possibility of the major ramifications this could cause (I. E. Damage, injury, death, etc. ) while backing up. The picture I am sending is taken from head height like I was looking at the mirror, which shows what I see every time I put the vehicle in reverse.
