Did you have a panic stop recently. Any conventional style rotor can/will warp when you slam on the brakes. It's happened to me twice on various Camaros.

Let me guess, 4th gens?

 

no and ive not experienced this on any of my vehicles to include My Shelby that goes on the road course race track where I go from 150mph down to 35, 100 times a day here in Vegas no problems . these santa cruz brakes are junk. I wonder if they warranty them?

 

If they truly are warped, I sure would think they'd warranty them.

I had a 1996 Subaru Outback that had wrapped rotors at 7,000 miles. That POS had the worst brakes, seats and engine of anything I have ever owned. The engine had a piston pin oiling design defect. They replaced the entire engine twice before 10,000. First one was bad. Second one was the same as the first one, while Subaru Corporate tore down the first engine and determined the issue. They claimed the third engine had a fix in it, but I dumped that POS a month after the third engine was installed. I had had all I could take at that point.

 

Could also be a tire or suspension issue. I've had a tire that threw a belt internally, that I only felt when I was on the brakes. Not sure how, but my best guess is the load changing on the tire itself caused the vibration to be felt through the steering wheel. I've also had alignment issues that ended up being the culprit of small vibrations when I got on the brakes.

Big vibrations/pulsating would probably be brake rotors. Hopefully the dealer takes care of you.

 

Rotors rarely warp, see the attached PDF. Could be brake deposits or uneven transfer of pad material. I would try re-bedding the brakes. To truly warp rotors you would have to basically have to melt them. I've tracked two cars (350Z and C7 Z51) and have beaten on brakes to point where they are red and smoking around Sebring - no problems. Granted that is using proper race pads.

 

anyone have the part number for the rotors? 2022 santa cruz

 

I just swapped to an SC Limited yesterday from a Kia Stinger. The Stingers are known for brake issues because they used cheap factory brake pads with the brembos and the compound from said pads would break down in clumps instead of powder and would cause braking issues/wobbles because the rotor surface now had bumps all over it. Kia changed my rotors twice in 28,000 miles for this.

Depending on who you ask you get two explanations. Ask the dealer and they say you're warping your rotor due to spirited driving and they'll make you beg for the repair to be covered even though it's absolutely 100% their fault.

Ask enthusiasts and they'll tell you that if you change the pads out for better aftermarket brands, you won't have this issue at all.

Now the test Stinger owners used to see if the rotor was fine was re-bedding the brakes by going about 50-60mph and slamming the brakes, doing this process twice back to back, which burns all build up and gets the rotor smooth again. If your braking is fine again after this then I would definitely look into some good quality brake pads and get those installed. Definitely look up other explanations for re-bedding your brakes so you're comfortable with the process before doing it. Should only take a few minutes.

Crap...now I'm worried that my SC is going to have this problem 🤦‍♂️

 

Took it to the dealer and all 4 were out of spec, they resurfaced them and got it back to me !! Broke them in and now all good!!!(so far)

 

They actually turned them? Most places just replace these days. Glad your back on the road.

 

I would have expected a replacement too, considering how new your SC is. It is also very strange that all four rotors were out of spec on such a low mileage vehicle.

Good luck! I hope that fixes the problem for you.

 

If you think these are bad brakes, I had a 09 Dodge Journey that I couldn’t get 10k miles out of a set of rotors. If you over tightened the wheels, they warp. Panic stop? They warp. Look at them sideways? They warp. I got so good at doing the brakes/rotors I could do all four in 90 mins. in my garage using a floor jack. THOSE were sucky brakes. Undersized (FCA started using bigger rotors/calipers on the 11’s and up). It wasn’t my foot either. My Jeep has 29k miles on it, everything original and over 80% left on the pads…

 

I had this rotor problem also, granted I drive down a long hill twice a day. I have about 9000 miles on my SC. So this past weekend I took my SC to the dealer and they said the front rotors were out of spec. The way they explained it was the rotor had hot spots... Anyways they re surfaced the both front rotors and oddly they feel better than new. Also, before I had a slight squeak when braking and now that is gone. I didn't break the brakes in properly when I first got my SC. Fixed under warranty, so I'm happy.

 

I experienced steering shimmy at 60 mph when i applied brakes. Seemed to vary depending on road. Took it to dealer, they said calipers were out of tolerance, plus they turned the rotors. This was at about 5000 miles and done at no charge. Everything working as it should now.

 

calipers were out of tolerance,

Wth does that even mean, Never heard that before. I assume calipers are all cast from the same mold? I can understand rotors being out of tolerance or warped. Maybe someone can elaborate?

 

I just bought a used SC with 6,818 miles on it. I would get a slight vibration when braking over 40. long story short, I just replaced pads and rotors. inside pad had uneven wear. the top pad is the outer pad. the hardware seemed dry to me

 

So, is there any reason that the Hyundai dealer wouldn't cover this brake issue? I just dropped my Santa Cruz off for its first oil change (5,120 miles) and mentioned that I can feel a judder when I apply the brakes and he made it sound like it was my fault and would let me know the cost. He said he had no knowledge of this being an issue with the Santa Cruz. I'm bracing for a fight, I guess...

 

It should be covered under warranty. Maybe it all depends on the dealer?

 

Brakes are considered a wear / maintence item, thus not covered by the warranty. However if determined to be defective within 12 months they should replace them. So its up to the dealer to make the call.

 

Unless a driver rides the brakes continually or drives aggressively, Brakes should go at least 30k. When I get on the Highway I hardly touch the brakes until the exit .

 

That is my feeling - but it's only a 'feeling'. I haven't seen anywhere that states Hyundai has to cover wear and tear items. Since the truck is new and only has 5,000 miles I expect them to, but I haven't seen it written anywhere.

 

they are warped again!!!!! FN less that 10000 miles!!!!! I own 6 vehicles and this is the only one that has this issue!!!!!! 2 Range rovers a Shelby (has seen track duty) F150, Harley Davidson, Subaru wrx none have evr warped as a matter of fact Ive owned 40 vehicles and never had warped rotors!

 

I've owned 30-something automobiles. Two had problems with brake judder - a 1991 Ford Tempo and a 2017, 2019, and 2021 Honda Ridgelines. My 2021 Ridgeline developed severe brake judder (the front right tire felt like it was bouncing off the pavement during moderate brake application at highway speeds such as slowing down on an exit ramp). Turning the front rotors was a temporary fix. The judder returned. The permanent solution was to replace the factory rotors with the cheapest aftermarket rotors from AutoZone.

 

Is a caliper stuck? Brake pistons damaged? Wheels torqued incorrectly? Hubs damaged? Something is wrong, because as you noted brakes don't warp as part of normal or even heavy track usage.

 

I have 4K on a new SEL P . I haven’t liked the brake feel from the beginning. They work fine of course but feel very soft. The Kona in the family is much more firm feeling. My 04 Silverado has firmer feeling brakes. Has anyone experienced the soft brake feel? Or is it just me?

 

I dont use the lane keeping or lane following assist specifically because they use front brake modulation to steer. I dont want constant brake application while driving so as not to exacerbate rotor warpage or uneven pad wear.

 

Light modulated taps on your brakes via onboard computer will not warp your rotors.

Mountain descents without engine braking will tho.

 

"Wear items" are covered for 1 year/12,00 miles; according to their website.
See bottom line:

 

Y'all are worried about your brake pads, I'm worried that the center console display is only covered for 60k miles 😭 that's whack yo

 

Considering most manufacturers provides basic warranty of 36month/36,000miles coverage (Ford, Honda, Toyota etc…) 🤷🏻‍♂️ They’d be wackier? 😂

 

Um duh, tunes are way more important than stupid stuff like actual safety items 🤷‍♂️🤣

 

Broke rotors are $100 each and you in your driveway with basic tools or any shop on earth can do the work for a few hundred dollars.


An infotainment unit replacement is a $3-5k dealership job.
Thats my concern.

I've got less faith in 10" flat screens than 13" hunks of steel.


If my stock rotors kept warping I'd just find another brand honestly. A decent set of pads and rotors will last longer than 30k miles.

 

Point being: the vehicle is still driveable with a busted infotainment screen. Without brakes; not so much.
