Alright so I have scoured the forums for information and knowledge pertaining to the brake actuator failure/malfunction. What lead me here is on Friday 1/4/19 the dreaded brake light Christmas Tree lit up while driving (late christmas present I guess ) On Saturday 1/5/19 I dropped it off at Sewell Lexus of Dallas. When I dropped it off I did tell the rep that if in fact it is the brake actuator module I would like to request support from Lexus for the repair as that has not been done on my vehicle. The rep called me today and explained that it is in fact the brake actuator, he stated its leaking and that caused it to malfunction and be disabled. He quoted a price of almost $2700 and said he had reached out to Lexus for support and unfortunately the request was denied. I told him I would have to think about it and give him a call back. I contacted Lexus corp myself and am awaiting a call back from the field rep at the latest tomorrow to determine if any support will be provided. I am also having the front end looked at as the car is pulling to the right and I have been experiencing some vibration from the front end(that has bought me some time as well to decide what to do), (I recently replaced all front control arms at an indy shop).
I logged into my account on Lexus owners site and the vehicle in service date appears to be 11/25/2008 that would put the ten year in service at 11/25/2018 ( from what I read the extended service bulletin covered until 150k or 10yrs in service whichever is first). I know that technically I am out of the ten year time frame for repair at 100% however I am very frustrated that this has come up only a month and 10 days out of the term for full replacement. I have heard the "sqwuak" for some time I just felt it would last longer than it has. If I had drove the car harder or braked different it likely would have been replaced at 100% covered within the ten year in service term. Am I S.O.L. or is there anything else I can do? The car has apprx. 97k mi. Any support or insight is greatly appreciated.

They determined you were not a “Brand loyal customer “. It makes me want to puke. Maybe you should tell him Lexus isn’t a customer loyal brand? What he really means is that you don’t wander into the dealership every three years with a fist full of cash, trade in your car for the newer model and get your brains beat out with depreciation so they can keep the party going. If it’s any conciliation, I’m a reformed Mercedes owner and there’s an even wider river of tears on the Mercedes forums around known issues that cause the secondary market huge heartburn. As Pwrdbym noted, this must be one big issue for them to extend this warranty 10 years or 150K; and then bust your chops for a month and 10 days?.At the very least, they should offer these actuators to anybody that needs one at dealer cost, and beat up their manufacturer for special pricing on them for the trouble they’ve caused. I’ve been a bottom feeder in the luxury used car market for years. Maintenance and part replacement is expected, but design flaws on inordinately expensive parts that should at least last 100,000 miles is infuriating. Good luck!

Is the “sqwuak” you referring to different than the clicking noise. I know there is nothing wrong with the clicking noise but I am starting to hear a different noise when braking. Almost like my brake pedal needs lube or something.

Julez the sound you are describing is definitely what I was hearing, best of luck. Be prepared to replace it in about 2 months time.

JLAWS the issue for me is not that parts will fail and this is a luxury car, I fully agree with that statement. The issue is that this part is an integral part of the braking system, without it you have no ABS, no skid control, no anti sway precautions, and probably more. With that being said it then falls into a NHTSA concern in my book as all cars are required to have abs as of sometime in the 90s. Those of you that have to get it repaired need to report it to NHTSA so there can be a recall issued.
The issue for me is that the company acknowledges the part is faulty by redesigning it around 2011 and again multiple times, and issuing a “service bulletin” “as a good will warranty”. When in reality they are just trying their best to get out of a recall situation and bad PR for the company. A lot of these cars are going to be coming out of the ten year in service warranty and a lot of them are going to need this part, it is unsafe to drive the care without the module functioning and therefore the company needs to issue a recall for said part as they have already acknowledged it’s an issue. Unless they are not in the pursuit of perfection in which case they just leave all previous or maybe “new” used car customers out to dry, either way it’s not ok in my book.
REPORT TO NHTSA IF YOU HAVE TO REPLACE IT

​​​​your missing the point JLAWS, and it seems like Lexus has your number with the term “goodwill warranty extension”. The whole point is that this part failing is a safety issue and should be handled as such and it has not. It should have been replaced long ago back in 2011 when they redesigned the part. Instead the company decided to wait it out and see how many people would come forward and hush them with a goodwill warranty extension. I have read in much detail regarding this issue and I am completely convinced that is the case. Many customers have brought their cars in within the timeframe making noises that show the failure is immeninet and the company said well it hasn’t failed yet so you do not qualify that to me is postponing at the risk of safety of their customers and I’m not ok with that. Especially for a world class companies supposed “flagship” vehicle. The ls430 was great the ls 460 seems to have missed the boat on reliability even if the motor and trans is strong these issues cannot be dismissed.
