FAQ: Vibration under braking: warped rotors? NO!

[Andy C]

Yeah, I was thinking about doing that. Not sure they'll cover "warped" rotors at 19k miles and 2 years of ownership, but it won't hurt to try.

A little more reading will help you a lot. The first post of this thread addresses your first question and my post just a few posts up addresses your second query. SMH.

Sorry to get you lathered up Andy, was totally not my intention. Glad you got your warranty swap, hoping my gets handled as well. How have the fresh rotors and pads been? I was looking at the Hawk pads as well. My only concern was not being able to get a warranty replacement because of whatever reason. I have a fairly good relationship with my Kia dealership and service department (we own 5 Kia's) so hopefully it will not be an issue, but if it is I was wondering if anyone had good results with just a pad swap without replacing the rotors.

But FIRST, go to the dealership and make them replace all 4 rotors under warranty. This is a known problem with our Stingers, KIA replaces warped rotors more often than you changes underwear. Switch the new pads in at the same time and start fresh with brand new brakes.

US warranty for rotors is 12k miles
Canadian warranty for rotors is 60k kms

I think @Freelancer may by out of luck for getting warranty rotors at 19k miles

Haha all good.

I had 26K miles when they replaced mine...so technically out of warranty. I did call Kia VIP beforehand but may or may not have been needed.

Kia will only replace pads with the us spec. It will take an act of God to get them to replace with the euro spec. My advice is get them to replace rotors and buy new pads from KNS Brakes. I just ordered Hawk HPS 5.0 F/R from them.

Also, they only replaced my front rotors and the wobble is totally gone. I am sure it will come back if I brake hard with the shit OEM pads, so I am taking it easy until the Hawks come.

Appt is Thursday, so fingers crossed. Did they have rotors in stock or did you have to bring the car back?

If rebedding (even the OE pads) works to eliminate the pulsating brakes, then your rotors are fine: they do not have cementite spots on them. If the rotors ever heated up enough to form cementite (hard spots that wear a lot slower than the soft iron areas), no amount of rebedding pads will accomplish squat: new rotors time.

My small dealer has to overnight them

Approved by Kia for front rotor replacement. Waiting on pads to arrive from KNS as my dealership said they would be more than happy to put them when they do the rotors. Rotors are in stock at the dealership and pads should be here Saturday. I'll schedule with the dealership on Monday, so Wed should be the day. Decided to go with Hawk HPS 5.0 front and rear.

Its good that they are replacing the rotors, mine just got machined under warranty. The vibrations are gone, so I'm happy with that

 

[Craig Mabrey]

My rotors were resurfaced under warranty (7k miles) and I had them install aftermarket pads. Super smooth for the past 3k miles.

I have kids in my car much of the time and don't brake hard. I anticipate what's happening with the lights, try to downshift with the paddles when possible, and have very infrequent hard stops. My prior Lexus IS350 made it to 80,000 miles before needing new pads. All that said, the shudder has happened to me twice in 30,000 miles on my GT2. Very disappointing...now searching for the right pad to swap out and see if I'll get more than 12,000 miles between braking problems.

How does IS350 braking compare to the Stinger?

I had my rear rotors replaced under warranty today at 31000 km (Kia North York - excellent service). Fronts appear to be good.

I want to replace the pads with proper aftermarket ones to avoiding killing the new rotors.

Question for Canadians here: where do you get your break pads and what pads do you get? I am in GTA and ideally would buy locally to avoid waiting for shipping from the US / dealing with customs.

I read all 30 pages in this thread but can't find links to Canadians stores - apologies if it was posted.

Personnally, I went with EBC RedStuff brake pads. I now have more than 3000km on them with new rotors on all corners and I'm done with vibrations. They perform incredibly better than OEM pads. You can't go wrong with EBC's Yellow or Red stuff pads. Only took 10 days for shipping from England back in May...and it only costs 350CAD with taxes&shipping! StopTech performance street pads are great too, Hawk HPS 5.0 is another good option.

One thing's for sure, everyone in North America who owns a Stinger should switch their pads for aftermarket ones ASAP, in order to avoid any further brake related trouble!

ASAP

As soon as practical. It doesn't make sense to mess with something that ain't broke.

It'd be nice if my local Kia dealership would've read this thread. I took my 2019 in with the complaint of brake modulation and they kept my car two days. Techline advised that they cut the rotors and test drive. I'm wishing that I never would've bothered. To make matters worse, they gave me my car back with excessive mileage and said they "fat fingered" the mileage in/out. I can't swear to the mileage in but it was in the 13Ks. I got it back with 14,110 miles on it. The service manager gave me the runaround and even got "frustrated" with my bringing this to his attention. The dealership has probably the rudest staff I have ever encountered.

 

[WRXtoStingerGT]

I apologize if I am "spamming" but posting here but I just created a thread about this same exact issue.

I did attempt this "self-bedding" approach but the problem returned. I brought in my Stinger at 3040 miles and they replaced the front pads and resurfaced the front rotors. Fast forward less than 100 miles later in less than a week and the issue has returned.

We have owned the car for less than six months and it has less than 3150 miles on it. This is really worrying us. The car is shaking when braking and there is this "thudding/shuddering" when using the brakes. I'm at a loss for words if I'm being honest.

Should I contact Kia of North America or go back to the Kia dealership? Never had such an issue before but would like to know what to do. I am open to all suggestions and advice.

Thank you everyone so much for your time and help!

P.S. - It seems that I am unable to post links so I am going to "quote" my post underneath here.

Car has 3040 miles on it. I bring it in to the dealership since the entire car is shuddering and shaking under braking. They confirm the problem and REPLACE the front brake pads AND resurface the rotors. Fast forward about a week and less than 100 miles later and I noticed the same issue has returned; but only happened maybe once or twice on the drive then went away. But the car is not braking properly as it should, just like when the issue was showing itself before. My vehicle is violently shaking when slowing down, especially at higher speeds, and the vibrating feeling is coming from the brakes.

I have owned and worked with different performance vehicles before and I know this is not normal. Should I contact the same Kia dealership and have them take another look or contact Kia of North America about this? I just want my car fixed. I do not know anymore if the issues are the pads or rotors but for a car with less than 3150 miles on it this is crazy. We haven't even owned the car for six months yet. This is really scaring us if I'm being completely honest.

I am currently located in Yonkers 10704. Please let me know what should be done. I am open to all suggestions. I am not happy at all that this issue has returned after less than 100 miles and not even a week has passed yet. Very alarming for a vehicle that cost this much in my opinion... and we have owned Lexus, BMW, and Mercedes in the past.

I'm on my 4th complete set of rotors - soon to be 5th.

60,000kms on rotors here in Canada. I have 47,000 kms on my stinger. - will schedule another dealer visit shortly to complain again (they have never actually fixed the issue, they just replace rotors and say - vehicle has been returned to normal operation.

then, shortly thereafter - pulsations..

Still on my original pads - I expect my next dealer visit will be - new rotors again Kia North America doesn't seem to have a solution.




ALSO - and this is merely my opinion.
Possibly, Kia North america doesn't have a solution cause they do not know of a problem. They are being consistently lied to by the dealers.
Saw this first hand.
Dealer thinks they are doing me a favour by writing down - Felt vibration, measured runout, runout out of spec - replaced rotors.
As if this guarantees Kia Canada will honour the warranty (seems to work)

BUT NO RUNOUT MEASUREMENTS re being taken (confirmed) - just numbers on a report to get warranty approved.
I feel as if I should measure the runout myself before my next visit
The limit for runout is just 1.57 thou. (I do not know if this is inline with industry standards)

I assure you that they are aware of the problem. They purchased my car back under the "Lemon Law" provision of my state's laws due to the brakes (amongst other things). The "Kia representative" (not dealer) was told of the multiple cases of brake repair at this one dealership alone. They know. Their response is precisely why I do not drive a Kia now.
