Who else has had warped rotors?

[Capecod]

I picked up my 2019 GT2 on Saturday with 79 miles on it, once I got on the Highway I noticed this issue, gets pretty bad when slowing down from HW speed.
So is it to late to bed the pads now that its shaking?

Boy does anybody read there owners manual anymore. It says right in there brakes need to be properly seated.

I quoted the manual. The way bedding brakes is described in this discussion requires vigorous (if not exactly "hard") braking. The manual says to avoid hard stops, and admittedly, bedding in does not stop the vehicle. So either way should be fine, as long as hot rotors don't melt locked on pads. But there isn't a "bedding in" process required to "properly seat" the brakes. Anything required is already done prior to delivery.

You are covered under warranty for a replacement, make sure you get new pads and rotors, then bed them in.

Probably not too late. Just read back over this discussion and acquire the methods of bedding in; they vary a bit, but essentially involved vigorously applying brake pressure until c. freeway speeds are brought down to sub freeway speeds; letting a brief cooling off period pass (a minute anyway); then repeating a dozen or so times.

This discussion might have even more useful information: FAQ: Vibration under braking: warped rotors? NO!

Thanks, I did read that,I'll try on my way home tonight.. I'm 56 and have never had to bed any brakes...LOL

I haven't ever done it either. And other than worn out pads, I've never had any shudder on any of my vehicles. Obviously, the instant you start to hear squealing, vibration or rough braking, you are supposed to get in pronto and get new pads. This rule I have followed, and even forestalled the need, by keeping on top of my brake pad condition.

Is there a TSB for the rotors?

No. It is a case by case basis answer under the warranty.

Can anyone who replaced front OEM rotors with Cquence slotted comment on if it improved the uneven wear, how is performance and which brake pads did you go with? I have these in my cart now with Stoptech ceramic pads; haven't seen a review of them yet. Thanks

 

[Manaz]

Changing the rotors alone won't fix the issue - because the rotors aren't the cause. If you use the same pads, you'll end up with exactly the same problem.

Better pads on OEM rotors would be perfectly fine.

Stoptech make good pads, their ceramic pads should be a good option.

The cynic in me says they're doing this to 'make the problem go away until it's not their problem any more.

It won't work out so well for them in Australia for instance, where Kia offer a 7 year warranty - they don't get to exclude the brakes from that because they're a consumable/wear item.

Even without a 7 year warranty it wouldn't work here, because statutory warranties don't over-ride consumer protections, which mean that if a reasonable person would expect the failure (and it's a product failure, not a wear and tear issue) to not occur at the age of the vehicle, then the manufacturer is still held responsible.

Gotta love a decent consumer protection scheme.

I went in 1 week past my year lease date and was at 15k miles and had to shell out the $410 for new rotors even though i was in at 5000 miles for the problem the first time. Anybody know of a way I can go directly to Kia to see if I can get some kind of warranty help on this or am I out of luck because the service department I go to refused to listen until after my 1 year time?

Go to Khartunerz and buy some new pads and install them or it will return. The stock pads are going to ruin the new rotors once again.

Call the VIP line and scream bloody murder. You have an early incident and it’s a chronic problem.

2018 Stinger GT. My front rotors warped at 8,800 miles. The dealer put on new rotors. They had a 1 year or 10,000 mile warranty. Now at 23,000 miles rotors are warped again. Not sure what is going to happen now. This sucks...

There's nothing wrong with the rotors. It's the pads. Tell them so - that they didn't fix the issue when you did report it, just hid it by giving you rotors with no pad material stuck on them.

Thanks, I will let them know.

Welcome, Kip (your "arrival" date is your first post, not sign on, imho)! If you've read through any of the brake threads, you should know by now that the consensus is that "warped" rotors do not exist. It's a term to describe the feeling of the brakes when the rotor face gets uneven from pad deposits, as Manaz says. We're just repeating the wisdom learned here. Quite a few links to other sites discussing/explaining what goes on with brakes and pads have been shared on this forum. I've read so many that I almost feel like an expert! Heh! I do feel like an expert in how to use my brakes properly. But others assert that they brake as economically as I do, and yet they have experienced this horrid decomposition of their pads all over their rotors anyway. I think that SOME of the pads that Kia sourced are compromised by production inequities. But MOST of the pads are okay. Those that aren't often don't manifest issues until long after the 12K miles warranty is passed. Kia has reached out to some of these cases with a "good will" gesture, not honoring the warranty, but offering to replace pads/rotors anyway. Good for them. In other cases, Kia has said "suck it up the warranty has passed". Oh, well! You won't know unless you try, again, I reckon.

I’m at 800 miles. I have no vibrations or pulsing...but I do have a roughness with light braking from 60 down to about 30. Sounds like a hummmmmm. Moderate braking or any other speed range and it’s smooth as butter.
