Warped Rotors every 10K miles - Honda CR-V 2012
We bought this car brand new and every 10k miles or so the car experiences excessive shaking when applying the brake. We took it to the local dealer and their diagnoses has always been bad driving habits or going through cold puddles of water. Both diagnoses are rebellious. This is a car my wife drives from to my daughter to school to the grocery store.
The dealer shaved the rotors multiple times and then they ended up replacing them. Then 8k after they replaced the rotors the car experiences the same thing.
I am not a mechanic but from the research i've done, warped rotors are a symptom for something else wrong with the brake system. My questions:
1. Has anyone experienced the same thing with this model car?
2. Should is take the car to a custom brake shop?
3. Could putting custom brake pads/rotors fix the problem?
4. Is there a site that rates cars according to reported problems with braking system?

2 & 3. You might consider having a reputable independent shop put a higher grade of rotor and pad on this vehicle, yes.
I have to say though that while you may have done nothing to cause this, in theory the dealer's comment that driving hot rotors through cold puddles of water is not an unreasonable explanation--but it would require a special set of circumstances, like holding the brakes while coasting down a long hill, at the bottom of which was a puddle of water sufficient enough to splash onto the rotors.
In your case though, probably turning the rotors to correct the warpage was not a good idea, as this makes the rotor even more susceptible to further warpage.
Another possibility --if you have ever had tire work done and if the wheel studs were over-torqued, that could cause this.
My guess is that the rotors were engineered just a bit too undersized for this car. They cannot dissipate the heat fast enough under certain conditions, climates, drivers, etc.
We have never had a warped rotor. the 2003 went 75,000 miles before the pads were replaced for the first time and they could have gone another 5-10000 miles.
And, we live in an area with lots of traffic and lots of hills.
In my days with Honda I never heard of this from other CRV owners.
So, I don't know. I know this isn't what you want to hear..
Thank you Mr_ShiftRight for sharing the link. I'm glad to know we're not going crazy and other people are experiencing the same issue. I think I may take it to custom break shop to see if better pads/rotors will make things better.
You might look into those slotted rotors and, perhaps aftermarket heavy duty pads.
Heat is what causes rotors to warp and maybe the slotted rotors deal with heat better. I know I see them
on a lot of high performance cars.
Even if this were to happen you would still have brakes on three wheels out of four!
Next time this problem comes up again, I'll take it to an independent shop and ask about other rotors or pads.
It turned out to be caused by something called rotor runout. Runout is the side to side wobble of brake rotor as it spins. When new, perfectly machined rotors were installed in my I30 one of the rotors had 3 times the maximum allowed runout. This was apparently due to a manufacturing defect on the axle itself. I took this car back to the dealer for the judder problem many times when it was under warranty, but they never checked the rotor runout.
Here's a Youtube video with details on how to check the runout:
The side to side wobble of a disc causes brake judder to develop very quickly. Machining the rotors helps, but due to the uneven thickness of a machined rotor on a problem axle, even a machined rotor warps quickly.
The solution for me was to install a inexpensive brake rotor shim to correct the runout. I ordered one from an online auto parts store, installed it along with cheap rotors and have now gone nearly 30,000 miles without machining the rotors. It is just now starting to develop a judder problem.
Perhaps you have a similar issue on your Honda.
Not sure that I will go back to Honda again.
