Having big problems with rear brake binding after car is parked for 4 or 5 hours. We live in Atlantic Canada and Dealer is saying it’s ‘common’ here. Had the issue again this morning. Both LH rotors have surface corrosion all over them and you can see where rear pad has grabbed the rotor, RH rotors are reasonably clear. Brakes cleaned by dealer 4 days ago. Car was driven 660Km yesterday (total KM on car is 6758km)

happened a couple times to me too. seems "normal".
although, the other day i was backing into my garage, slowly and to straighten it out, and a loud crack came from somewhere at the back of the car! i thought i ran into something, or ran over something (like a plastic bottle), but nothing. I wondered if it was the brakes, maybe one of the pads cracked off or something, but i visually i saw nothing out of the ordinary. I hope it wasn't the brakes :sad:

I've had that "crack" sound as well. It happens after the car has been parked for 12 hours or more, and it is just as the car begins to move. If I park on a hill (facing up hill), it happens every time. Wish I knew what it was, but so far I haven't had any other issues.

Cast rotors will, rust no matter. Pads will stick sometimes as a result, it's normal.

I’m in Florida, this happens to every time it rains. I think it has to do with the pads but I know nothing. The dealership thinks that maybe it as well. But who know at the moment. Warranty is wonderful. I’ll update after I get my baby back. Btw this is not normal, sorry

It happens to me every time it sits for a couple days and when it's humid. My old Ford Fusion did the same thing with the rear brakes. I've only experienced this with the rear brakes, not the front. It never did anything bad to the Fusion in 5 years and I doubt it will with this car too. If I had to guess it's probably the pads and the rotors cooling off at different rates and when its humid that could create adhesion. Just a hypothesis....

See "snapping sound" post. Not normal. Could not drive car for 2.5 days...finally was able to crack pads off rotors by forward/backward throttle application...

Happens to me after I wash the car or the rotors get wet from weather if I don't drive the car afterward. I figure I can see if someone makes a less aggressive pad than the stock ones and settle for less brake performance or wait for the aftermarket to make an exotic rotor (e.g. Porsche Ceramic Composite PCCB) and pad combo to keep or maybe improve the stock brake performance for a chunk of change. Since I bought the VN as a cost effective daily driver that can be track driven for now I'm going with keep the stock set up and deal with the rust. That's just me.
Yeah this is just a side effect of the pad compound they put on there so the car can withstand track use. Brake pads are a compromise one way or the other like that usually. I've heard the brake caliper and rotor are from another Hyundai/Kia model (IIRC one of the magazines said they're from the kia K5) so maybe the pads from that model can be used as an alternative for those who want more streetable brakes for daily use.

That's a good point and an option for those who don't mind the downgrade in brake performance and don't want the dust and rusting issues of the stock pads.

It used to happen to me alot but im right under 5k miles at 7 months and i dont remember it happening for a few months now. Dont know if its a break in thing or just depends how hard you're driving it? Or maybe the frequency of use? I dont use the car every day but when i do use it i use it alot. Definitely used to freak me out a bit. I also haven't has the long start up problem anymore. Very weird now that i think about it as these issues used to happen almost daily for me.

It happens to me sometimes too. It's always when it's been wet out- either rain or heavy dew. Sometimes it's loud and startles me, I thought I ran over something stuck under my tires the first time it happened. I actually got out and checked .
But it makes the noise, the car goes fine and that's it so who cares.

Take them to the dealership and if they can’t fix,it’s a lemon. at the moment I’m going through the FL lemon law process. its important to take it to he dealership for record,400 miles on my first visit. 6800 now but they still need to do a full refund because i took it to the dealership right away. Waiting will cost you and this can lower the value of the car as well as making it potentially dangerous. this is our brakes were talking about we have to stop.btw I’ve taking my car 4 times with repairs done and a last chance fix,all failed. So refund or replace at full cost with compensation for the times I’ve taking it to the dealership. DONT WAIT!!

A lot of people in here apparently don't understand that higher performing brakes come with a cost:
-More noise
-More dust
Since the OEM pads have a high metallic content, the dust from them rusts very quickly and the face of the pad as well, this will cause them to stick to the rotor.
lol @ doing a lemon law for brake pads rusting. It's not going to cause your brakes to not work, just means they stick if they are engaged (i.e. parking brake) and sitting in the wet. I got around this by parking in gear on flat surfaces and lightly engaging the parking brake when not on a flat surface.
P.S. The G-Loc pads I have don't do this, because they have a higher carbon content than the OEM pads. But they come with a trade off in that they create a ton of dust and are very squeaky.
