Four problems related to service brakes have been reported for the 2009 Lexus LS460. The most recently reported issues are listed below.
Car currently (9/14/15) has 46,289 miles, now with clunking noises during braking. Lexus corporation aware of problems with control arms and brake actuator. Dealer diagnosed as both control arms and brake actuator. Lexus refuses to honor replacement fees of replacement parts.
Dashboard recently had 5 warning light lit up warning of check abs, check vsc system, check brake system, check brake hold system, and brake malfunction, with the following additional warning below the above five items "stop the vehicle in a safe place immediately. Contact dealer". I was a few blocks away from where my car is serviced (not a dealer) and they diagnosed the following fault codes: c1241 abs main relay power source open, and c1391 anti-lock brake actuator & electrical control unit. The cost to repair this is $2,300! my car has a pampered 72,262 miles and is garage kept. My repair shop, jc automotive here in st petersburg FL when calling around to locate the replacement part was quite surprised to find a jacksonville FL dealer has 35 in stock. John celona, owner of jc auto told me this means they must be replacing many of this item because in no way would a dealer stock this many of this part. If Lexus is replacing so many of this part there should be a recall. Reading the Lexus forum and other online Lexus sites, this problem occurs as early as 12,000 miles and is a covered warranty item. I will contact Lexus about his issue also. I hope you will investigate and consider making this a recall item. I have attached five photos. The vehicle was stationary and the lights appeared immediately after starting the engine.
From a complete stop or an abrupt brake pedal press and release there is a very loud rumble from the front end of the car. It is a rumble or creaking noise and does not inspire cconfidence in the braking system of this vehicle.
Braking, at times, is irregular, during normal operating conditions. Feels as if the braking system is misreading data. Took car to Lexus dealer about 2-2. 5 months ago and told rotors were a bit warped. Dealer turned rotors and said everything should be fine. Problem did not fully resolve. About a week ago, noticed same issues and returned to dealer who informed me that the rotors needed turning again and that they could see a depression on one rotor made from the brake pad. I was informed that the rotors can get hot in traffic and I likely pressed too hard on them in traffic. However, this occurred during the months of mid-February through April and climate has been moderate. Between these two visits, I had driven approximately 4k miles and I have not ridden brakes unduly hard. After most recent visit to dealer, braking is not always smooth and feels like a control module is not calibrating the braking pressure correctly causing improper pressure on rotors and periodic irregularity when braking.
