Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“When I go to apply the brakes or of I'm coasting slow, the car jerks twice(once while the car is slowing down, and a harder jerk right before the car stops) every Lexus forum I visited where people had 2006 Lexus GS300 awd's(with the same exact symptoms), they were mis-diagnosed being told it was their transmission, when in actuality it was their ecu that needed to be replaced. That is a computer failure, so I don't understand why there aren't recalls on this.”

“When making right hand turns and applying heavy throttle, engine braking or torque management engages causing the car to forcefully resist acceleration. Happens on wet or snowy roads or dry conditions. This control system also keeps the rear wheels turning when braking in slippery/snowy and icy conditions, even when completely stopped. I've almost been hit several times when trying to merge into heavy traffic in right hand turns. Flooring it causes the car to basically try to stop itself. …”
