As the failure persisted, the vehicle entered "Reduced Engine Power Mode" and the check engine warning light illuminated. The vehicle was taken to an independent mechanic shop where a diagnostic check was performed, and it was discovered that the fuel pump was defective and needed to be replaced.

Transmission & drivetrain
I purchased this vehicle in 2015 - it has been dealer serviced and has never been in an accident. At just under 90,000 miles on the odometer, a major fluid leak started. 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 without warning, the engine could have seized on a highway, leading to a crash. This failed seal should be designed to last far longer than 90,000 miles. Premature failure of this kind is highly likely secondary to a defect in design or materials. I have complained to Lexus, which is unwilling to take any responsibility for this. …
The vehicle has 119285 miles on it. I have started to see oil leak from the transfer-case/transmission. I called lexus back in August 2023, they were aware of certain vehicle developing oil leak problems. They issued recall on certain vehicles and issued a TSB for oil leak repair. I called lexus today and took the vehicle to the dealership. There is an understanding that my vehicle won't be covered under recall even though the problem is known to lexus. This issue may lead to unexpected breakdown of the vehicle and lead to loose of control of the vehicle.
