Three problems related to brake light on have been reported for the 2008 Lexus LS460. The most recently reported issues are listed below.
I was parked with the engine running for approximately 18 minutes when suddenly, I heard a beeping sound in the car it would not stop!!! I turned my engine off in hope to reset whatever it was but as soon as me foot touched the brake the beeping resumed. It was raining and I had not clue of what it was. At this point, all of the brake light on my dash came on . I went out of the car popped the hood and didn't immediately recognize anything. I then went back in the car and with the beeping still in my ear, decided to head home. That's when I noticed I could not stop my car !!! the brake was stiff and I literally had to force my car to stop by applying as much pressure as physically possible to my brake pedal. I took the car to my mechanic and after diagnostics he stated it's the abs pump and brake actuator.
Abs brake light warning came on then brakes failed soon after.
In may 2017 I replaced rear brakes but the "squawk" noise when releasing the brake pedal persisted. On 6-8-17 I returned to Lexus wh dealer (customer # 171829) and the tech requested a test ride. At the curb, I engaged brake, and tech saw the abs brake light. He immediately diagnosed the brake actuator unit. Mileage in/put on invoice 207972 (attached) verifies the car never went on test ride for diagnosis. Scott at Lexus cust care claimed there was no warranty recall at that time and advised me to consider the Lexus wh service mgr offer to repair for $5000 less $1200 good faith discount. I inquired if this was a safety issue and was told no by technician it was just a noise. Several months later, problem worsened so I researched issue and discovered service bulletin issued April 2016 for brake actuator. On Dec 11 2017 engaged Lexus cust care again and eric young, agent, checked my VIN and advised my car was included on the sb. He also noted the Lexus dealer claimed in June 2017 the car did not fail yet they tried to charge me $5000 for a repair. When I requested notes or tangible proof to take to the dealer, eric called to set appt at dealer for me and I dropped my car on 12-11-17 on 12-12-17 the Lexus service mgr now claimed the car did not qualify for sb repair because no codes or lights on dashboard. Dealer failed to acknowledge the battery replacement in oct 2017 which would have erased codes. Lexus service mgr new repair quote is $3900 less $1200 = $2700 + tax. (again no invoice provided) I refused to retrieve my car until corp and/or dealers put their decision to deny my claim in writing. Lexus supervisor claims they do not put proprietary information in writing and would only provide attached email. No invoice provided by dealer I believe my vehicle is covered under warranty policy bulletin 16-01 aka warranty enhancement program - zlg.
