Owner report 11548062 · 2023-10-03 (October 3, 2023)

It turns out that the rear main (crankshaft) seal had failed, causing a leak of transmission oil. No warning lamps or messages appeared. This failure resulted in an extraordinarily expensive repair, over $2,500.00 at the dealer, Lexus of Greenwood Village (Colorado). It was not covered on warranty. This is a major safety issue - had I not noticed the leak, which occurred w…

I immediately turned on my four ways and pulled the car over to the side of the highway. As there…
