Continued Rotor Issues

[84Phins]

I'm back in the service department with vibration occurring during braking at high speeds. It again comes down to warped rotors, third times a charm perhaps?

Well, nothing too bad, except I'm now responsible for paying a fee since the warranty for this type of equipment ran out about 1 month ago.

Is this something typical with this sort of vehicle or should I make another call into Kia to get this settled?

Not sure if you checked out this forum. Some good info...

FAQ: Vibration under braking: warped rotors? NO!

It's your pads friend, you need to get new pads and burn the deposits off your rotors. US spec Stingers got shit pads unfortunately.

Buy aftermarket pads from Khartunerz and be done with it. Using stock pads that have the current compound formulation is going to do this over and over again.

I am not sure that's how it works unless I'm wrong. If I swap pads, I can "fix" the vibration? I'm very close to ordering 2 pc rotors and pads.

Replacing only the pads will not remove the material already on the disks.
The disks on the other hand can be resurfaced or replaced. Just make sure to bed the brakes in properly after replacement.

Personally I will be replacing both as the issue has come back.

That's what I figured. So my quest for 2 pc rotors resumes.

Some pads are shit. Apparently most OE pads are not shit. Otherwise we'd have seen a TSB on this ages ago.

How much are they charging you for this?
Im hitting 20k miles soon, bringing it in Thursday for rotation and oil change, want to bring up my vibration during braking

 

[NS_Stinger]

I already have this issue at only 12,000kms. I'm not hard on the brakes at all either...

I'm having the same issue. Took the car in almost 2 months ago and they only resurfaced the rotors. Fast forward about 5 weeks and the vibration is back. I took it to the shop this past Saturday and they are now going to actually replace both front rotors and replace the pads.

My question is, what should I do once I pick the car up from the dealership? Should I bed the brakes? If so, how do you do that?

Should I turn right around and buy aftermarket pads since that seems to be what's causing the issues?

Initial issues began at around 8,000 miles, it's now happening again at about 12,000 miles.

I'm waiting on a call from my dealer, they ordered back rotors and pads, I will try the bedding process as soon as I leave the dealership.

sorry Merlin, it's pretty clear that most of our US OE pads are shit. It came out when they were track testing the Stinger and a ton of people on here have the same issue. This isn't a defective pad, it's the material pad itself. It's functionally fine and clearly works great for it's intended purpose, but leaves deposits like crazy.

If anyone is getting new rotors, go ahead and get new aftermarket pads. Don't even bother with the OE pads. Yeah, Kia should have replaced all these pads for free but they haven't, it's best to just bite the bullet and spend a little money and make the problem go away.

How much is it for pads/rotors?

Covered under warranty, noticed it the day I picked it up with only 79 miles.

I only see the front pads on Khartunerz, do we know if the rear has the same issue?

It will be back with the stock pads.

That is incompatible. "Leaves deposits like crazy" makes any use of the pad into a vibrating mess. If MOST Stingers are not experiencing issues then most pads are not leaving deposits. That means that the way most people drive works with the OE pads. There have been a few complaints on the forum from drivers who assert that they "are not hard on the brakes at all", etc; yet they have deposits and vibrating brakes. The vast majority of our thousands of members ignore even commenting on this issue just like they ignore saying anything about the paint on their cars. That means either one of two things: most Stinger drivers are dense and don't care; or most of us don't have issues with our brakes (paint, or whatever else gets complained about).

The amount of deposits is going to depend on driver behavior and environmental conditions which varies. The threshold for brake vibration before it becomes annoying enough to complain about is going to vary as well from driver to driver. Just because 100% of drivers aren't complaining about this issue doesn't mean it doesn't effect every single US car. The paint issue is different, that was a defect in the manufacturing process, the brake issue is a component design flaw.

I know you love your car but you need to stop turning a blind eye to the issues this platform has. Car manufactures would probably love for an army of Merlin's to buy their cars, it gives them a reason to not have to fix known issues, which in turn means more money in their pockets. I on the other hand welcome the feedback as it helps to ensure the platform continues to get improved.

The forums are a small sample size of Stinger owners, not everyone that owns this car is going to chime in when they have this issue on this forum. I've had this issue for a couple months now but haven't brought it up until I saw this thread which reminded me of it. Many of us have busy lives and running online to report some brake shake isn't at the top of our to-do list haha
