Two problems related to service brakes have been reported for the 2004 Lexus GX470. The most recently reported issues are listed below.
Lexus is selling vehicles with bad brake actuators. I took it to them twice and which they say they don't know why I'm here the noise and why my brake pedal was rattling when I look on the Lexus forums I see several people complaining about the brake actuators are going out on their vehicles some vehicles only have $34,000 on them. The dangerous part is that you get no warning lights or anything if it goes out and you're on the expressway you can not stop the vehicle at all, one person even blogged about how there's went completely out on them luckily they were driving up in the driveway but the vehicle never stopped. Lexus is charging people anywhere from 2 to $4,000 to fix these when they know that several of their vehicles are having these problems while still new. I just took it to Lexus again last week and the servicemen said it sounds like the actuator is going out if it is then that's going to be $4,000. While driving the vehicle I hear a lot of clicking up under the hood and you can feel the vibration all the way through the brake pedal.
My wife was driving our SUV and was attempting to park it in a bank parking lot in niles, IL. The SUV accelerated suddenly without my wife pressing the gas pedal causing her to drive over a green space, hit a sign on bank's property, drive over a large bush and a wire fence at an adjacent park and finally stop after repeatedly pressing the brake pedal. We towed the car to the Lexus dealership and from there to a body shop. We had the car for 8 years and this is the first time that this issue occurred. A police report was filed and the damage was assessed by our insurance company.
