Toyota and Lexus hybrids can lose braking assist

NHTSA campaign 19V544000 · Reported 2019-07-24 · Toyota Motor Engineering & Manufacturing

high How serious is it? About this label

Losing brake assist and stability control makes a crash more likely, so treat this as urgent; the notice does not tell owners to park the car, but get it inspected quickly and watch for brake warning lights or a hard pedal.

What's wrong, in plain English

A pump that helps power the brakes can fail on these vehicles. If it does, the system that keeps the car from sliding or spinning in a turn stops working, and the brakes lose their power assist. The brake pedal will feel much harder to push and the car will take longer to stop. Because of this, these vehicles do not meet the federal safety rule for stability control. A dealer will check the brake booster pump and replace it if needed.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm your vehicle is affected. 2. Call your Toyota dealer at 1-888-270-9371 or Lexus at 1-800-255-3987 (recall K1L/K0L, or K2F/KLF for Lexus). 3. The inspection and any pump replacement are free.
