Just wondering who else is having brake issues in Australia

[5tinger]

Is Kia AU doing anything about the infamous brake vibration?

Is Kia AU doing anything about the infamous brake vibration?

Some dealers are replacing rotors, some are machining rotors & some also pads.
it’s the pads that are causing the issue, by changing the same OE items with the same it is only a bandaid & the problem will more that likely retur, it’s a dog chasing its tail.
I’m now running dba slotted rotors & pads since January 2020 without issue.

Stinger was purchased with only 23km on the odometer in May 2019.
And I'm very gentle on the brakes. Not sure why it shudders when braking. It's been this way for the most part.

How do the dba pads perform compared to oem?

The OE pads leave material on the rotors & it builds up & causes the shudder.
dba performance is excellent & I have no issues with them after just over a year of use.
Have a read of the tech Q&A

Yep, I've been going back and forth for almost a year with Kia.
They have machined the pads and rotors twice. And replaced them once.
This only solved the issue for about a month or so.
I'm going to purchase the DBA kit(around $1600)

Is there anyway to be compensated by Kia ?

Mine is going into the dealer next week for a "detailed inspection", as I have complained many times to the dealer and now recently to Kia. Have been previously told no major fault found, although the dealer did say I have a minor warp in a rotor, and I would have to pay $390 to be machined. I have felt this since 3,000km and am now up to 24,000km.

I am not convinced it is the rotor though, as it comes and goes and can vary between a minor/major rattle felt and seen in the steering wheel.

It is definitely worse when the brakes are hot, but I am not abusing the brakes at all... both Kia and the dealer did suggest I was driving aggressively, which is absolutely not the case. I did then ask if the brakes have to be replaced every time they lend a vehicle to a motoring journalist, and they said "no" - well, it's not through brake abuse then is it!! haha

Also, a major clue... I hand wash the car once a week (maybe more!) - and am using garden house as you would expect.
After every wash the brakes feel great - and for the first few applications there is a little noise and grinding going on, which is surely some minor rust or whatever left over from the washing... but the brakes then feel great, NO STEERING RATTLE!. A day later, then I get the steering rattle again - so surely this is to do with pad build up, and has nothing to do with a warped rotor?

This is the only fault on such an amazing car!

Your issue seems to me to be the material the rotors are made of, the pads grab then slip at a very high velocity which transfer up the steering wheel as a vibration, the rust you speak of and the good brakes are the pads biting and not slipping for the first few brake applications, then once you wear off the rust, the problem returns..................I would get some aftermarket rotors and pads and I bet your problem goes away.....................KIA have put cheap rotors on all these vehicles I would guess and the rotors are SHI*

My Kia had done about 30,000ks it was sent to warranty. So make sure they measure the thickness of the rotor and pads.
And that will elimate the "wear and tear" argument

 

[antsGT]

OK, great update for my issue. I called Kia and they arranged for my dealer to do a thorough inspection of the brakes - and when I collected the car at the end of the day, it had been fitted with new rotors under warranty.

Previously the dealer said there was no issue at 3,000 and 10,000km (when there clearly was) and at 20,000km they then agreed their was a minor warp in the rotor and I would have to pay $390 to have them machined.

Today they instead said that were was indeed a significant warp - and Kia agreed to replace under warranty.
Thank you Kia!

Whereas previously the dealer had checked and confirmed that my vehicle had not been fitted with the known problem wheel "mounts" which were known to cause a warp in the rotor on earlier models, but today they said that actually my vehicle DID have the known disk warp issue.

It is not clear if they have just replaced the disks or if they have also resolved the issue where the wheel mounts cause the rotor warp to occur, I will see what I can found out.

I can say that it is really amazing the drive the vehicle with smooth brakes once again!


Incidentally, my vehicle is known as a MY20 (so I have a heated steering wheel), but was lovingly assembled in Sept 2019.

Aren’t they Brembos. Not sure they are cheap.

What's this "mounts" issue all about....first I've heard of pad deposits being described that way.

 

[antsGT]

They have said nothing to do with the pads or deposit build-up for me, the rotors have been distorted due to the wheel mounts applying uneven pressure back onto the rotor - something like that.

 

[5tinger]

My GT is about to have it's 20,000km service at John McGrath KIA in Woden (Canberra).

Since 5,000km I have been getting a steering wheel shudder under braking - and at the 10,000km service they assured me that nothing was wrong, which was mighty frustrating.

I am going to tell them the same as before, that I am getting a shudder under braking -- but it comes and goes and varies in intensity. It seems to be worse when the brakes are warm, and to not do it when cold - but it doesn't do it all the time when hot - and I am not really ever doing any massive stops and am driving far more sensibly than a Stinger deserves too! Actually, I think it gets worse when driving around town slowly with the family in the car, and it may not be as bad when I drive with more spirit on my own - but I am still driving sensibly.

I can not see or feel any marks on the rotor itself... this is the only fault with such an awesome weapon of a vehicle!

This is exactly how i'd describe it. Vibrations occur when driving sedatly and applying brakes from speeds of about 70-80kph.
No vibration when the brakes are cold and no deposits are observed on the rotors.

Unacceptable if you ask me.

I purchased my Stinger new in 2020. When picking it up I asked if the brakes had been bedded in because I had read that this helped, The salesman advised me that it was not required. By 3oookm I noticed that the shudder was starting so visited the dealer who sent their Tech for a drive with me. He advised me that Kia Aust would not do any rectification unless the steering wheel was almost shaking out of my hand and any parts fitted would be OEM and that the shudder would return .He advised fitting aftermarket pads myself and wearing the cost . At 12000km I got fed up and while getting a FEA check at Pedders Frankston, Simon advised that they have been fitting Akebono pads to Stingers and had no bad feedback so I got them to fit a set to the front at a cost of $250. So far, so good.
Yesterday I rang Kia Aust to advise them what I had done and to ask why they have not done anything to eliminate the problem. While I was talking to him, he said that I must have too much free time and hung up on me.
This is upsetting considering that my family has owned 5 Kias since they arrived in Aus.

That is a shame.

Unfortunately the person you were talking to on the Kia support line was not emotionally invested enough in order to escalate your call onto someone who could help further. I assume they are trained to provide minimal help unless the caller is persistent? I guess they get problem calls all day, as nobody typically calls to let them know everything is working great!

When I called them last year they were not wanting to help, but I was able to argue a little and I was fortunate that the person I was talking to decided to look into it further and they instructed/paid the dealer to do a full investigation. The same dealer who said that I didn't have an issue then said that the rotors had a serious warp - and it was all replaced at no charge.

They also spun some story about the wheel mount bolts being the cause, which was a known issue on earlier models but was supposedly cleared up by MY20 - and this was even checked as being OK by the dealer on my early complaints. It was only after Kia made them do a further look that the dealer then found issues. I was ultimately thrilled with Kia, but disappointed that my dealer wasn't the expert that I needed earlier.

I have had a close look at the way the wheel is mounted, and have no idea at all as to how this could have any affect on the rotor.

I am very pleased to report that I have done 12,000km on these new parts and no issues have returned!

 

[Nawdy]

I have exactly the same issue - it really sounds like it's a common problem. Had the 30,000km service done a few weeks ago, and got exactly the same feedback....nothing at all wrong with your brakes.
Considering taking it to a brake expert for a diagnosis.

 

[Fridge]

I replaced the front pads with DBA street performance and they were good for a couple of months. But the steering shuddering back. Maybe the XP pads are better?

Did you have your discs machined when you replaced the pads?

I've got the same issues at $30,000. Been getting worse since 25k ish. The hard braking thing isnt working anymore either to clean them up. I cant justify nearly $2k on a rotors and pads so was going to try machining the rotors and DBA SP's but maybe now thiking about the XP's on the front like "Stinger GT SS" has posted about previously. I see that Stinger GT SS has done both the pads and rotors to good effect but wondering if anyone has cleaned up (machined) their OEM rotors and upgraded just the pads? and if so has it worked?

Also are the DBA XP's much louder/dirtier than their SP cousins?

 

[antsGT]

Just a FYI that my brake shudder problem didn't return.
I have now done 56,000km, with 35,000km clocked up since Kia had the dealer replace my rotors back in May 2021, and the issue didn't return - which was both a surprise and relief.

No doubt. And great that they did that for you. I raised the issue with my Kia dealer and they said they knew of no issues with brakes, no issues with brake pads or rotors or anything else to do with brakes, and while they agreed that there was significant shudder, and that 25k was early for that to be happening they said I had to get the discs machined at my cost as its wear and tear and not covered under warranty so I am trying to find a solution that doesn't require rotor replacement.

Out of interest does anyone know what pad Kia uses as their OEM's?
