Do Not Sell My Personal Information Jump to content

Recommended Posts

Curious how many Lexus owners have had a brake actuator failure.  We have a 2013 RX350; we bought a new RX450, and parked the 350 over the holidays planning to sell.  When I started it, numerous warning lights came on: the "Check AWD System" light, the engine light, and the VSC and Traction Control System lights. Upon taking the vehicle to our dealer, were we told that the brake actuator assembly needed to be replaced.  The cost to do so was $3,855.12.  I found there was a NHTSA recall on 2/12/2014 for this issue, requiring a software upgrade to avoid the failure of the brake actuator.  The dealer advises that software was updated in 2015 - which obviously didn't work because the brake actuator still failed.  Lexus is refusing to cover this, even though the predicted failure occurred anyway.  If anyone else has experienced this, please let me know.  I am preparing litigation on this issue.

We have 2013 lexus rx450h. Brakes started making what can be described as a seal barking type of noise we took it to dilorenzo a replace the brakes that did not stop the problem then after several other appointments they narrowed it down to what they think is the brake actuator. A few months afterwards all the warning lights came on and now they're telling me the Hybrid battery is no good. I've read where they are linked I'm not sure shocked that Lexus will not cover this especially after they replaced a cracked dashboard on my 2004 Lexus 350 when it was 10 years old and had more than a hundred thousand miles on it!

Are you certain that your 12V battery is fully charged? Sometimes a weak and/or old battery will produce various warning messages/symbols.

Lexus said they fixed the problem, and refuse to fix it now. All lights are on, and I was told Break actuator is the problem.

      Hey there everyone i have a few questions on the abs pump/ Brake Booster / Accumulator squeakbafter pump engages. From what i understand this is a fairly common issue with this pump/ master cylinder. I dont actually have a Gs300 so mine may be slightly different (crownmajesta). What im wondering ia if there is anyway to even temp fix this issue as i need to have a vehicle inspection and they failed it previously due to the brake warning indicator light coming on. Even if anyone knows of a way to avoid having the light come on so i can deal with this issue at a later date. They failed it based on the indicator light alonebas the inspection check sheet says the hydraulic system passed and all other braking components passed. Any suggestions would be greatly appreciated. Please point my in the right direction if i have misposted this.

      Anyone know where I might find instructions/guide for replacing the left rear brake shield on an 2007 ES350? It seems everything must come off to replace it, including the parking brakes. I could wing it, but it would be nice to have some info going in.

      Hello everyone, this is my first time posting on a forum. I am wondering if anybody has done tt supra front calipers on the front, and moved the stock sc400 front calipers to the rear. My rear caliper seized up and I was looking at buying remanufactured tt supra calipers all around, but the rear calipers are absurdly high in price for some reason no matter where I look. So I started looking at different caliper options, ls400, supra, remanufactured sc, etc. But maybe this could be a new setup unless somebody else has already thought of this before (which I have a feeling somebody did). Thanks for the help in advance.

      Hey All! Bleeding my brakes was one of the items I tackled for the 120k mile service on my car. Using a pressure bleeder made it fast and painless. In fact the most tedious part of the job was getting the wheels off each corner as I worked. 
      Of course I created a video detailing the process:
