2023 RDX Tech SH-AWD.

Is the squeaky-brakes-when-backing-up a solved problem? My car has been doing this for a long time now and sometimes it is VERY LOUD. So loud you'd think it was a clunker and it is embarrassing when there are friends in the car. 2 services ago they said they couldn't reproduce it. At the last service, the service advisor said that there's no change to the part so even if they replace it, it's likely going to keep making that squeaking sound. I shared videos of it with them.

Is this a solved problem or are most folks "just living with it"?

I have to take the car in tomorrow for unsolved AIS and a new infotainment issue, so I was wondering if I should insist that the brake issue be addressed as well. If it's truly an unsolved problem, I can live with it. Otherwise, I think I deserve to have a car that backs up quietly.

 

There is a service bulletin to fix:

I waited until my pads were fully worn so I got free brake pads out of it. Though it looks like they might not cover waiting any more with recent TSB updates.

 

Thanks. Did it completely fix the problem for you?

Also it looks like, for the newer cars, they are replacing a like-for-like part number. If so, how is that expected to rectify the problem.

 

Noise went away for my 2022.

 

Service advisor said they have already applied the TSB to my car, so unless Acura comes up with updated parts, it wouldn't make sense to repeat it. So looks like I have to live with it.

 

What did the dealer actually do or replace? Is it your rears, fronts, or both that are squeaking?

 

They applied the full SB. See attached.

 

My 2024 has had this problem since I purchased it with 1700 miles. It only happens when you first back up in the morning. I took it in and the dealer said that the car had all the latest parts installed so there was nothing he could do.

 

You might (or might not) want to try some . It is sort of a flexible rubber cement stuff, which you apply to SOME of the places you might alternatively apply brake lubricant. Specifically, between the metal backs of the pads (not the braking surface) and the caliper. On the "ears" of the brake pads where they ride on the carrier, you still want to use the appropriate brake lubricant. Some reviewers use the word "lubricate" or "lubricant" in describing this CRC stuff, but it is not -- more like a permanently soft PlastiDip. The bottle says that it is for pads without shims, but many reviewers use it between the shims and the pads with a good rate of success.

Maybe get an opinion from a brake shop.

 

My car makes it whenever I start backing up after it’s been sitting for a while which is anything more than about 30 min. If I go shopping for groceries when I get back to the car and back out then it will happen. It doesn’t happen or happens to a lesser degree in warm to hot weather. It typically never happens when my drive ends with backing up (e.g. backing into my garage at the end of a trip or backing into a parking spot when I arrive at a store).

 

Like many of these kinds of problems, it sounds like it's temperature-sensitive. However, it seems like this brake squeal problem has been going on for a long time with the RDX. Absolutely amazing that they haven't been able to put it to rest. None of my previous Hondas had this issue.

 

I had a similar TSB taken care of on my 2022 RDX in winter of 2023 and it initially seemed to have worked but the noise has returned with the onset of cool weather. I've just learned to live with the noise. In my experience, to get the noise the car has to have sat long enough for the brakes to cool off. If the dealer takes you car for a test drive, more than likely they will not experience the issue.

 

Agreed.

 

My brakes also started to squeak when cold, but after warm up its fine. I ignore it. Its hard to believe that I am hearing brake squeak issues 6 years later after release
of 3rd gen. There is nothing difficult to make quiet brakes, unbelievable

 

I have a 2022 and a 2023....they both have it when backing out of garage when its cold. After that it goes away. I didn't know there was a TSB, maybe I will get it done.

 

Not sure if any of you all are mechanically inclined; however, when I perform 'brake jobs' (new pads; brake pad shims; caliper bracket retainers; rotors) on my vehicle(s), I reasonably 'lube' the areas indicated by the arrows below:


Acura states on the April 2, 2024 19-053 TSB to apply the included ATE Plastilube paste, as shown below, only to the rear brake pad set.

However, if you look at the updated May 30, 2025 19-053 TSB it completely omits any mention / depiction of applying ATE plastilube to the rear set and shifts its application to the front shim kit?

IMHO, the techs should be reasonably applying the ATE plastilube to the areas, indicated above, to cover all potential 'metal to metal' (front & rear brake calipers) contact surfaces to avoid continued 'squeal' after the customers vehicle has been visited for this issue.

 

I think we can safely say that Acura has known about this issue forever but hasn't tried to fix it in production.

 

It seems like it's been a challenge for several brands, not just Acura. I think it started being a problem when they change the pad material to prevent/minimize brake dust. So now we have clean wheels, but we have to deal with noise. I do wish they were able to address it, though. I think they have made some changes because the part numbers are different. It's just that we have a problem even with the new ones.
