2016 LEXUS RX Power Train Problems

Upon parking after 20-mile drive, severe leak of transmission oil from transmission oil cooler area, no warning messages/lights or fault codes present.

The reason that did not detect the oil leak right away was that I have almost not used the car at all for the past two years due to Covid situation. Second, I have parked my car on my lawn, so that could not see oil drops. Third, I put my trust on Lexus and Toyota products, so I have not inspected for oil leak periodically. This oil leak has soaked many parts of the engine,...
