Sonata I45 (YF - 2011+) :: Grinding Noise After Brake Change
Sep 21, 2015
I changed my tires, brakes and rotors last August. I had installed EBC YellowStuff. I also greased(using SilGlyde) the slide pins and bled the brakes.
Last weekend, my car was making a weird noise when I hit the brake, so I removed the front tires and noticed that the front passenger side outer brake pad was completely gone and the inner brake pad still had 25% life left, but it was tapered(image attached).
I know when this happens, usually it means that the slide pins need to be greased, but they were plenty greased from my last year's brake change. I still greased them, but now I hear grinding noise frequently(not all the time) when I am accelerating at slow speed and sometimes at even high speeds.
There is no fluid leaking and I could only see surface rust on the pistons. Its driving me crazy, because I can't figure out what it is. I am thinking of just replacing the slide pins anyway to be on the safe side.

We have changed the brakes and the caliper on the right passenger side of our 2008 Hyundai Elantra. When we brake, we a getting a grinding sound. We had to change out the caliper 2x before we got a working one. Now with a working caliper, we are still getting getting the loud grinding sound. We had greased and removed all rust in and around the caliper. The brakes are new.

My car is making metal grinding noise when coming to a slow stop when you are stuck on traffic or going into your driveway. You can hear the sound and feel the sound.
I had this issue a year go and i took it to the dealer and they told me that i need to replace my rotors and my front brake pads.
A year later the noise came back and they told me that i need to replace my pads. I replaced my front break pads and a month later the noise is back. I went back and checked my pads and the pads were still new.
I only hear the sound when braking after driving in a heavy traffic or on a stop and go traffic. I don't hear the sound when i start to drive or driving in a non traffic condition.

This noise started this week. Grinding when I take my foot off the brake when in park and parking brake set. What is causing it?
A guy at work said brakes. The front brake pads were replaced last year. Original rear.
Just over 90,000 miles.

My brake booster is making noise for a few months now. It works ok and brakes are strong but the noise is there. Any way to quiet it down? Or how much the replacement might cost?

Two months ago I started getting a clanking noise from the right front when I accelerated from a stop, or stopped and moved the car backwards from forwards or vice versa. I pulled the wheel and noticed pretty work brake pads, with the inboard pad completely shot. Car has 34k miles. The left side inboards and outboards were about 50% worn and were worn evenly. Sure enough, I had a sticking lower slide pin on the right. I cleaned everything up and lubed all contact points, and replaced pads and clips. I removed, cleaned and re-lubed all slide pins and holes with the appropriate silicone brake lube, and confirmed that they are siding freely. The problem is that this worked, but did not completely eliminate the problem. The noise still happens about 1 out of every 5-10 starts once the car starts to roll after the brake pedal is released. The rim seems to rotate ok when jacked up and I am not getting a pull. A mechanic buddy of mine said that in these cases he just ends up replacing the whole caliper.

I have a 2012 sonata that has issues from day one. ?
New issue is: For a couple days now I've noticed a crackle noise when I break. It is only when I am coming to a complete stop that the noise happens, not the full time i actually have foot on break.
Not thinking it is the bearings. Thinking it may be something within my suspension.

Just got a 2012 Limited 2.0T about 3 weeks ago. Didn't notice until last week that there is a noise coming from drivers front tire area at low speed (15-20mph). It sounds like a thin piece a metal is getting snagged and then snapping back into place. Took it back to Hyundai and they pulled the wheel and said everything looks fine and that it's due to new brakes needing to "wear in". At the time it was very limited when you would hear it, in the past week it's increased to an almost constant noise until I get over 20mph. I've searched and can't find anything dealing with this particular noise, what exactly I should look for when I pull everything apart? I'm more inclined to try and fix myself than believe the dealer. I can't seem to isolate it to a particular thing when driving, it does it on turns, going straight, stopping, accelerating.

Is it possible to change the songs on the steering wheel on my iPhone 5 when I'm connected via bluetooth? Works fine with USB but not the iPhone.

When I move the wheel to the left, I get this metal grinding sound (similar to rust on brake rotors/worn down brake pads). It happens when the foot is off the brake and ONLY when the wheel is turned to the left.

So, I have had this weird incident happen a couple times. The first time it happened was probably a month or so after getting the car (2013 Sonata 2.0T Limited). I was parked on our driveway, and it's on an incline. I started it up, but the brake pedal was super hard to push down. Once the car started, everything felt fine, and other than a casual "Huh, that was weird." I didn't really think anything of it. Have been without incident for months.
Then today, it happened twice. Parked in the same spot, started the car fine this time, but I went to turn it around in the driveway and almost took out our shrubs because I went to brake and the pedal was stuck. Pushed down really hard and got the car to stop. Put it in park, and tested the pedal a couple times... everything was fine. Was nervous, but took the car anyways. Happened again in the afternoon. Got out of the store and thought I was going to be stranded in the parking lot because this time the pedal was stuck and at first I couldn't start the car. Luckily, it eased up when I pushed down hard and it started, then all was fine again.
I have done a little looking and saw vacuum booster and master cylinder mentioned for possibilities, though no one's experience that I have seen sounds just like mine, nor did I find any that are Sonata YF specific. I already got my switch recall taken care of, so this is something different. Only 7,000 miles on the car. Gonna bring it in to the dealer this week, but just wanted to crowd source opinions in case they can't replicate the problem. I hate feeling like I can't trust my vehicle... especially when it's almost brand new.

I've been lowered on coils for the past 6 months. I have been running aftermarket wheels since day one. I switched wheels out and lowered a little in the front. Drove it yesterday morning at 10am,and all three lights came on. Stopped turned the car off and turned it back on and all the lights went away. Drove the car at 6pm and the lights came on. Stopped turned off and on and the lights are gone. Don't know whats going on . The cables that I believe are the abs/ speed sensors are fine no rubbing on the passenger side the wire circled looked like it was at a weird angle but idk. Drove it this morning and no lights. No clue whats going on.

My son parked the car and I noticed the brake lights were on. After depressing and releasing the pedal a few times the lights go off, then 2 or 3 seconds later, they're back on even when the pedal is released. This happened all of a sudden. I'll pull the switch in the morning and test it, but what else could it be but the switch, right?

Just put on eibachs and car is randomly making a grinding noise when slowly accelerating or braking.. Also noticing a fairly loud clicking noise when going in reverse. The noise isn't consistent and seems to happen more right after startup. I haven't gotten the alignment done yet and was wondering if this could be the problem. Will try and post a video soon.

I just bought a 2006 Sonata LX V6 a few days ago and in almost every way it seems like a great car. My '08 GLS V6 which gave me 150k great miles got totaled in November, which really sucks, but I wanted to find another '06-'08 V6. I noticed when I started it for the test drive that the car made a bit of a grinding noise on start up. I didn't think much of it and figured that the warranty from the dealership would cover any problems.(I probably should've checked earlier, but the dealership's warranty only covers cam and lifter noise and engine failure) After I looked into the issue more, I found out that it is a fairly common problem on the early 3.3's with the timing chain tensioners. I'm pretty concerned based on just the nature of the repairs and the cost I've seen for them.
I'm the third owner so the 5 year/60k warranty is expired, but I know there is a TSB out for the issue. I can't find the TSB anywhere but I've heard to have it repaired the car has to make the noise on start, sit 10 minutes, and make the noise again. If it does, the oil needs to be changed and the test repeated again. Since I'm running Hyundai 5W-20 and an OEM filter already, I tried the test on my own. It made the noise on start, sat 10 minutes, and made it again. It is only for a couple seconds, but it's still concerning to me. I guess what I'm trying to ask is if what I've described is covered under the TSB. I really don't wanna have to worry about something like that right now, so my next question is whether the issue I have is detrimental to the motor. My worst fear would be to have the chain jump a cog on the cam gear and slam valves into pistons.

My neighbor and I have a similar problem with our Prius'. At around 35,000 miles, after an oil change at a dealership my 2011 Prius had a loud rattle while driving on a famous grade in my county called "Waldo Grade". It may be known as "Robin Williams' Tunnel". There was a loud rattle that occurred from the rear of the car and goes away on the flats. I brought it into a Hybrid Shop and the proprietor drove it for a day and reported that he could not duplicate the sound.
The noise has since disappeared and now I have 39,000 miles on the car. My neighbor had the same problem with his 2015 Prius: around 35,000 miles, after an oil change at his dealership, loud rattle and banging near his rear brakes. But his rattle occurred while braking down the San Francisco hills in the rain. My neighbor brought his car to his dealership and with this complaint and they reported that their driver was unable to duplicate the condition. He's waiting for another rainy day in San Francisco but it's unlikely that it will be soon. Is there any connection to the similar miles or oil changes?

My cruise control works just fine when my headlights are off as do my brake lights, but when i turn the lights on the cruise won't engage and the brake lights don't work. I've got 150K on the car so no longer under warranty...

My vehicle: 2013 Sonata Limited - 4500 mi. When I park on an incline, set the parking brake then release the foot brake, hear a 'creaking' noise from rear. Dealer says "it's normal and nothing can be done" ? I don't think so...

I have a 2012 Sonata for 4 years. In the past year I've experienced the ABS, Brake, TC lights staying on. Then had a bad battery and a headlight go out. Got all that done but after 4 months on new battery, it failed, and the 3 lights came on again. According to codes, dealer says the issue is a valve and they cannot give an estimate for repair but to tear down the valve and probe to find it, will cost me $132. That doesn't set well with me so I elected to drive on with lights on. They did say the battery & headlight issues were not related to the 3 lights staying on.
