I have a 2019 ES 350 Ultra Luxury with 29,800 miles. The brakes squeak when applied while in reverse. I have taken it in to the local Lexus dealer for repair, however they said they found no issues. The squeaking is both bothersome and embarrassing. Any advice?

 

There is a Technical Service Information Bulletin (TSB), L-SB-0008-22 Rev1, Front Brake Squeal/Squeak Noise, out that may be applicable.

 

Thank you very much, I will show this to the Lexus service writer, how did they not know or research this.

 

30000 miles almost, how much thickness they have?

 

I'm not sure, I rely on Lexus mechanics knowledge.

 

Are they ever replaced? If not I think they are worn, and your hear the low brake pad indicator that touches the rotor. You can hear it only when you drive in reverse.

 

i had that happen on my 2015 ES. Only one mechanic was able to fix the sound after numerous attempts at the dealership.
Just have to find the right mechanic. Good Luck

There is a fix - be persistent !

 

Do you have to subscribe to a site or service in order to obtain info on TSB's for your model/year?

 

Perhaps but that condition probably applies across the board at a huge percent of repair places. If the diagnostic check doesn't give them a code a lot of younger mechanics don't know how to go much farther. Lack of training and experience. Ive read that it's an industry wide problem to find enough mechanics.

 

I don’t think that Lexus allows their dealerships to bring in people that didn’t pass all the Lexus req’s. The problem is they are lazy to check.

 

For the TSBs that are in the category of mandatory reporting to the National Highway Traffic Safety Administration (NHTSA) those are all publicly available - all that is needed is a web browser and an internet connection. There are several web sites of varying utility, ease of use, and searching/classification quirks where you can the information. (Some lump all TSBs for 7th generation ES 350s under model year 2019 ES 350, etc. so you needed to have some flexibility in how you go about searching for TSBs for your particular vehicle.) Some of the places where you can located TSBs:

1. The NHTSA web site is the master repository. There's a "Check your vehicle safety" search box on the right side of the initial web page where you type in year, make, model (with drop down completion menu list), or VIN that will take you to the appropriate starting web page for the desired vehicle. At the top of the resulting page is safety rating related information. Scrolling down you'll find a tab menu list "COMPLAINTS, RECALLS, INVESTIGATIONS, and MANUFACTURER COMMUNICATIONS". Selecting MANUFACTURER COMMUNICATIONS (for 2019 LEXUS ES 350) is where you'll find all the mandatory reported TSBs. (There's also a listing for the ES 300h model.) While all the TSBs are there they aren't displayed in the the most convenient form since they're spread across multiple web pages and you have to manually expand each entry to see anything really descriptive on what the TSB is about.

2. The CARCOMPLIANTS.COM is probably the easier web site for quickly scanning through the a model's TSB's (derived form the NHTSA master list). Once you've navigated to the web page for the model you're interested in, you just scroll down through a list of the TSBs with brief descriptive summaries. That makes it easy to see what's been reported and quickly find the one(s) you want to look at closer. For each TSB there's a link to page with an expanded summary description with a link to the NHTSA filed pdf copy of the full TSB. There are a few quirks to this web site. The majority of all 7th generation ES related TSBs are found under the 2019 LEXUS ES 350 174 TECHNICAL SERVICE BULLETINS (TSBS) list with a few others seemingly specific to the ES 300H found under the 2019 LEXUS ES 300H 24 TECHNICAL SERVICE BULLETINS (TSBS) list.

3. ClubLexus has a LEXUS Technical Service Bulletins search tool; however, a least for the 7th generation Lexus ES the results are pretty dismal in that many of the NHTSA listed TSBs aren't found in the search results list.

Those are sources of the publicly available TSBs due to mandatory NHTSA reporting requirements. Although I haven't specifically verified it, the paid subscription Toyota Technical Information Service most likely has additional TSBs covering things that don't fall within the mandatory NHTSA reporting requirements.

 

A few months ago took it in for the brake squeak issue, at that time they said the brakes were fine and they could not find any problem, however the squeaking persists. I made an appointment referencing the TSB provided by grp52 (Much appreciation grp52).

 

grp52, thank you very much for providing this information, I attached the info to my online service appointment, the service writer called to inform me this was not a recall but a TSB, to which I replied "I'm well aware I just want it fixed, I will cover the cost". I was provided a 2023 ES350 a as loaner (multiple mechanics on vacation repair may take a few days). Dropped car off Friday was ready Tuesday. When I arrived my bill was $0.00, yes zero dollars, he said Lexus even covered the cost of the lost privacy screen clip/installation (I ordered 3 weeks prior $74.20). My vehicle is covered by Lexus CPO warranty (I was given 3 years instead of the usual 2 since the selling dealer was late sending in my paperwork to Lexus) I was EXTREMELY happy and surprised. Was considering going back to an MB E350, this is giving me pause as only coffee/soda/water/pastries are free at my MB dealer LOL. My Lexus service writer has been AMAZING, the sales portion of the dealership subpar, IMO adding non-negotiable $5,000 - $10,000 market adjustment to M.S.R.P. of new vehicles ($20,000 to the RZ 450e, the only SUV I would buy) however the service department is amazing.

 

Did they resolve the squeaking brake issue and what did they do if they resolved it?

 

my advice would be to pull the pads and inspect, clean, reinstall, and lube the pad brackets/ears/channels and contact points between the piston and shim plates. make sure the pads and rotors are stock.
