brake squealing

I've read a lot of threads on the 2019 RDX brake squealing in cold and wet weather I'm curious as to why nobody finds this as annoying as I do in a brand new high end vehicle is it the fact that the people saying dont worry about it live in a warmer climate to me it has become so bad that I'm questioning whether I made the right move buying this vehicle I always said Acura was the best running car I ever had until now I've tried to get the problem fixed and the dealership claimed there is no fix for it that it's under investigation which I'm sorry there's always a way to fix something anyone else having a concern on this topic please respond ive gone as far as contacting customer relations and still not getting anywhere with that

Every car no matter how high end or low end will have break squeal in cold/damp/wet conditions itís just the laws of physics and itís hard to escape that.

See examples here:The cure really is to warm up the brakes with some braking and itíll go away after a few minutes.

A slight squeal when the rotors/pads are cold and or wet is one thing, I know what that sounds like after owning 6 other vehicles from all different manufacturers. None of those cars have ever made a squeal this loud and prominent. This brake squeal that some of us are experiencing is not what I consider normal, and the closest thing I can compare it to is when the pads start eating into the wear indicator. In fact the other day on my way to work I'm pretty sure my brake squeal was louder than the public bus next to me.

I've owned and maintained about 10 cars in my life (a mix of used and new) and I have never had squealing brakes. I have driven a friends care that squealed, so I know what it sounds like. Here's a interesting example, I own a 97 BMW M3, my friends car that squealed was a 95 BMW M3, stock brakes use the same p/n's. The difference between our cars is that the stock pads are semi-metallic and contain graphite which causes unwashed BMWs to have nasty black brake dust on the wheels. My friend switched to ceramic pads with low dust that was whitish. The aftermarket pads did not come with anti-squeal brake shims so he used a spray on rubbery "stop squeal" when he replace his stock pads. After 6 months he replaced those aftermarket pads with stock pads - no squeal. The stock pads have the anti-squeal shims (thin metal plates covered with a rubbery coating). My other car is a 2002 Lexus RX300 and I replaced the pads with Akebono ceramic pads that come with a high temp grease to be used on the pad to caliper interface to prevent squeal. These pads don't squeal, but when wet, the grab like crazy until dry - the first time I drove in the rain, I though I was going through the windshield if not for my seat belt.

My guess is that either the brake/pad system was not well designed (I wouldn't have believed this, but I've seen other threads that say that previous Acura models, cars and SUVs had brake noise problems), the pads where installed incorrectly, the pads are defective, the new brakes were not properly bedded, or the discs are glazed/warped. The most common cause of brake squeal is a high frequency vibration of the brake pad where it is clamped by the caliper - hence anti-squeal shims being coated with a high temp rubbery coating.

I talked to the service department about brake noise. They said that they did hear it on mine, and that they have a TSB for brake noise, but it only applies after 3,000 miles. If your car is still new, they'll tell you to come back later.

Do you happen to know the TSB number?

brake squealing

not sure as to why your dealership is misinforming on the vehicle having to be over 3000 miles to be eligible for a fix while there waiting on a tsb I reached out to Acura customer relations and explained my problem with this they called the dealer and told them to replace the rotors and break pads I will keep you posted on how this works out

I've reached out to Acura Relationships and will be dropping the vehicle off back at the dealer for them to look at the issue. Will update on this issue as I have more information.

Mine started squealing today morning (it rained whole day yesterday and night temp was around 45 F). It went away after 5 minutes of driving in stop and go traffic with continous braking. I have 900 miles on mine, have it for 2 weeks. Wondering if it is ok for new brakes to squeal.

I also faced another issue with brakes. Vibration was felt when braking downhill to slowdown on freeway. Grade was around 8%. Vibration was felt in steering and seats. I have started a separate thread for that. Will get the brakes checked at my dealer once I complete 1000 miles. They asked to wait till I complete 1000 miles. Below is link to the thread.

I too have been getting brake squealing with the colder temps, it is annoying, and if it continues, I will have it looked at. I have not had squealing brakes on any of my previous cars, and it is annoying on a 45k vehicle. Brakes are a weak link on this vehicle, definitely one of my least favorite things about this vehicle.

I live in Seattle, WA. Current temps have been around upper 30s - 50s fahrenheit; fairly moist / wet.

I'm not seeing brake squealing on mine. My car was built late August and got it in September.

Mine was built in Oct. I hear the squealing only with windows down and only in morning with the first start.

Just got my car back from the dealership, replace all 4 rotors and pads. Will test it out in the next couple of days to see if the issue is resolved, initial feedback is no noise when I pulled out of the dealership.

Did the dealer agree to replace by themselves or you had to call acura?
Also did they find any issue with brakes as such?

I heard this same sound with my Aspec RDX yesterday in Wisconsin. It sounds like the ďsqueal indicatorĒ that most pads have that you shouldnít hear until the pads are fairly low on life.

I had a couple squeaks today. Car was cold and had been sitting for a week while I was in Florida. Only did it for a second and went away after a few stops.

I wonder if this could be related...

https://www.caranddriver.com/news/ho...-recall-brakes

The 2016 and 2018–2019 Honda HR-V, 2017–2019 Acura MDX, and 2018–2019 Honda Odyssey minivan are affected, including those that may have replacement brake parts from a prior service. Hydrogen gas may become trapped in the brake lines due to "insufficient coating" of the rear brake calipers, Honda said. When bubbles form in the brake fluid, the hydraulic circuit becomes compromised. Under braking, pressure in the line compresses the gas and decreases the force of fluid rushing to the calipers, which causes the pedal to feel soft and can reduce stopping power.

I doubt it, the car brakes great. I think honestly it has to do with the pad type they use, mine squeal for about the first 2 brakes, sometimes only the first, and then it goes away, I think it has do to with the pads needing to heat up a bit, also thinking about it these pads were never truly broken in. I was reading a lot of audis have the same issue due to the high performance brakes they use.

Maybe you guys should also include whether your car is garaged overnight or left out in the driveway.

My 2016 ILX has a break squeal problem too. They were replaced under warranty after Acura issued a TSB. Apparently the materials were not great in the originals. Never made a peep after I had them changed. (http://www.urvi.net/forumfiles/SB/B16-004.PDF)
Hoping the same will come eventually for the RDX.

When I brought mine in to the dealership for an oil change I mentioned the brake squealing and the service manager said they had been notified about it and changed out the brakes for me. I still hear some squeaks, but not nearly as bad as it was before they were changed out.

No brake squeal here so far. But it's been out in the rain only once and was parked for a couple hours in the rain too. I got mine in October.

Iím experiencing the brake squeal pretty badly lately. Iím at 3,700 miles and havenít had the need for an oil change yet so havenít done anything about it. Iím in upstate NY and itís been very cold lately with the squeal getting worse and I donít think cold weather is any excuse for brakes squealing in a $44,000 car. I had a 2017 RDX previously and at 1,200 miles had rotors replaced under warranty due to excessive squealing. At this point, Iím thinking itís the brakes Acura uses.

I have had the same issue with my 2019 RDX and struggled through the same issue on my 2106 RDX. It started happening with my 2016 a month after I got it in August; brought it in three times and they could never replicate it or had ANY other issues with other vehicles. I simply gave up and dealt with it only to discover that they had issued a TSB for it and it was the number one complaint of that year. It gives me hope that you have already been able to have the rotors and pads replaced. I have never experienced this with any of my other new cars besides Acura.

Anyone has your brake fixed? I picked up my RDX 3 weeks ago with about 800 mileages on it. The temperature dropped below 40, the brakes squeal for the first 4-5 mins of driving.

Brake Squealing

Just took our 2019 RDX back in today for the second time due to the brake squeal. I was told that Acura is aware of this problem and working on a fix. Originally, they had recommended replacing the rotors and brake pads, but my service department stated that they have done that, only to have the noise return. Therefore, they are no longer making that recommendations to Acura Service departments. They stated that there is nothing they can do at this time. They projected that it would be within 3 months that a solution would be found. I was told that this is a problem with the A-spec line, which is what I have.

I was told the same thing when I took it into acura last week. The service team is waiting on a PSA to fix this issue if anyone has a PSA number let us know here so we can take it in to resolve the brake squeal.

Usually, Honda/Acura will issue a TSB ( Technical Service Bulletin ) when they work out a solution to a common problem with one of their vehicles. If you're waiting for a Public Service Announcement, it could be a long wait.

My brakes kinda grind more than squeal. I'm not sure if it's from flash rust on the rotors, or an issue with the pad material, but it doesn't seem to affect performance and I've decided to ignore it for now.

The noise is caused by the FNC brake rotors. they are an anti-corrosive rotor that acura is now starting to use. they are still trying to correct the issue. i bought my 2019 rdx in july when it first came out and noticed the noise at arounD 3500 miles. of course i inquired at an acura dealer and my research came to this answer. i am close to someone who has the insight of whats going on. Acura is still trying to come up with a permanent fix for the issue without eliminating the FNC rotors. they are big on using these rotors because of all the beneficial characteristics of it. they are having minor setbacks in providing customers with a quality product, but when they get this issue fixed, the idea of the FNC brake discs will be a superior benefit with the acura braking system.

Me Too

For what it's worth, my 2019 RDX Advance has 1135 miles and the brake noise started today. I park inside at work and at home. Temperature in the 40's. It's not quite the same as brake squeel, but it's close. Here's hoping Acura figures out something soon.

Does Everyone Agree This Is Temperature Related?

I live in Toronto. When it was -20C last week the brakes squealed and squealed. When I parked underground at a hotel this week the RDX was at about 12C and there was no squeal when I departed.

I took my RDX to shop with less than 2,000 miles on it. They said brake problem has no fix at this time but ordered new pads & rotors as a "band-aid"
