“While driving, the navigation monitor screen has gone black and reset 10 to 15 times. When this happened, on 2 to 4 occasions, a red electric power steering warning light comes on for a few seconds and the steering hesitates. This happened while driving on I-5 at 60+ MPH. It didn't happen after I slowed down to less than 50 MPH.”

“My 2007 ls460 Lexus with 100k miles has a failed brake actuator assembly ascertained by a Lexus and toyota dealer. This was a confronted problem by toyota for failure of the o rings within the assembly. The actuator abruptly went out while on the highway at 70mph causing brake fluid to not go to the right calipers. There is a recall for 150 k mi or 10 years, whichever occurs first. However. My Lexus was out of warranty in may, 2018 and they will not offer any help whatsoever because my warranty expired aprox. 1 year ago.”

“Brake malfunction error was shown on the speedometer screen with five lights (ABS, vsc, brake, traction control light, and warning light).

Pulsation and noise were also noted. Dealer advised that the brake actuator part (44050-50110) was the cause of the malfunction and noise. Lexus tech and advisor noted that this is a a very common issue on this particular model - 2007 ls460.”
