2013 Lexus LS Brakes Problems

“After retrieving my vehicle from the Lexus dealership following diagnostic service, I drove the car home with no electrical issues. All hub electronics, displays, and interior systems functioned normally during the entire drive. The next morning, while the vehicle was parked, turned off, and untouched overnight, the brake actuator pump began running on its own. I recorded video evidence of the pump operating without any driver input. This uncommanded pump activation drained the battery to the point where the vehicle would not start. …”

“My ABS Brake System warning lights all came on a few days ago, giving me error codes c1253 and c1256. These codes pertain to a manufacturers defect with Lexus, wherein Lexus generated a customer convenience program that said any LS460 that is less than 10 yrs old OR less than 150k miles can be brought to any dealer and have this brake system replaced at Lexus expense. Please see the attached Lexus notice to dealers. My car is 13 yrs old BUT has only 108k miles; so I asked Lexus Corporate to approve my repair and they denied it due to age. …”

“I am detailing an alarming and persistent issue with unexpected brake activation on my 2013 Lexus LS 460.

“For 2 years now I’ve been getting intermittent abs and traction light come on. It never showed a code when a scanner was plugged in. Every now and then the light would come on when I start the car. As soon as I drive it’s gone. Now I have the brake icon on too and my brakes are very weird with it grabbing really hard at times and slow to release. It’s the brake actuator that everyone has problems with. I only have 76k miles on my car. I had the valley plate leak at 49k miles. So these 2 things are problems everyone have that Lexus isn’t admitting it’s their fault. …”

“The ABS system failed. Mechanic stated it was the ABS actuator. Left front wheel locks up when brakes are applied with force. Safety is jeopardized since the ABS system no longer works. Cannot bring vehicle to safe stop in an emergency braking situation. The problem was reproduced by an independent service center. The vehicle had not yet been inspected by the manufacturer, police, or insurance. Lexus has been notified and said that I just missed the window on the service bulletin, which ended in March of 2024. There were no warning lamps before the system failure. …”
