I have already posted a "general" explanation concerning brake rotor rust however it seems several posters are undeterred about "blaming" Hyundai and or filing reports with NHTSA. The description concerning your experience about having a brake service every 15,000 miles to aleviate this rust issue is vague. I personally live in the rust belt and Pa has never been accused of skimping on salt/corrosive liquid chemical snow and ice removal application and yet I have never experienced a need to have rust "ground" off my rotors every XXX miles. The rotor and pad interaction (when the brakes are applied) burnishes off any light rust that WILL form on the rotor overnight or when the car sets idle for any period of time. I have owned Hyundai products and in this respect they were/are no different from the Honda Civic we now own. I also own a 1995 Dodge Stratus and by coincidence just had the front pads replaced this past week-end. I had the opportunity to see my front rotors (approx 2 years old ) and they are clean with no evidence of any excess rust. I drive this car summer and winter and accrue over 22,000 miles per year. I do wash the car frequently especially in the winter (to the tune of several times a week) so does that have a bearing??? I am sorry but I simply cannot see a reason to believe this should be a Hyundai problem or a problem at all for that matter.

I have the same problem, The dust built in my real rotor, then the dealer said the pad was worn out and the rotor could be resurfaced. I have to spend $400 to change all my rear brake. I contact with Hyundai, they blamed I did not maintain the car and I am in the high salt area. I am in MA.
I will fill the complain, could we go further ?

2007 Sonata needs brake pads every 15K

I own a Sonata that is now on its second set of rear brake pads at 32,000 miles. Having owned cars with mixed city and highway driving now for 35 years, I don't recall having replaced brakes much ever before 60,000 miles much less the rear brakes on a front wheel drive twice in 30,000 miles, it is just shocking.
There seems to be wide spread agreement that this should not be happening but not much resource.
Today when picking up my car, they said they had fixed a recall Brake Switch Recall which they assure me had no baring on the brake pad wear. Perhaps this is true? But hard to believe.
I see the one post offering a place to file a complaint. I guess that will be my next action. That I am no longer going to get my service done with Hyundai. My trust is gone.

My 2007 Sonata has 26K miles, and I just paid the Hyundai dealer to replace the rear pads and re-surface the rotors. The service manager explained how he believed the rear brakes wore out so soon: Corrosion on the caliper guide prevented the caliper from returning to a “rest” position once the brake pedal had been released. As a result, the calipers were applied continuously, resulting in premature wear of the caliper pads.
Hyundai subsequently denied my request to cover this repair under their warranty.
I am by no means an expert when it comes to cars, but after seeing several similar stories on this discussion page, it seems to me the premature wear of rear brake pads is a SYMPTOM of the real problem: the caliper guides are susceptible to rust. If that is indeed the case, we are talking about a VEHICLE DESIGN FLAW affecting a rather important component.
I urge those of you with similar experiences to a) Write a letter to Hyundai Motors of America; and b) file a complaint with NHTSA's Office of Defect Investigations. If anyone has another suggestion for follow-up, please share it with this forum.

To all that are complaining about rear brakes wearing out "frequently" In the recent past rear brakes were simply along for the ride. They did little in stopping the car. I too had a 1987 Taurus on which the original rear brakes lasted about 100,000 miles. I said "wow ain't that great....go Ford" but in reality all it meant was the rear brakes did little in participating in the stopping of the car. The new Sonata (for certain and other makes as well) now has a brake proportioning valve that distributes the braking forces to include the rear wheels. This means that for the first time the rear brakes now have to do their fair share so....they now wear out! Suprise, things that work wear out.....

Since when are caliper guides a wear item?
Those of you saying get over it's car and other stupid remarks sound like Hyundai reps or dealers.
My '95 Honda  198K miles and 2000 Excursion 137L miles have never had a caliper guide wear out (I am the original owner of both.)
I live in upstate New York where we get over 250" of snow per year.
Our 2008 Sonata with 13K miles is now squeaking because the pads are hanging on it's caliper guides.
If the brake pedal was hanging up causing the pads not to retrack, it would be a warranty repair.
I'm complaining to dealer ownership then to Hyundai if I need to.

Same problem with my 2008 Sonata. Dealer said it was normal at 20,000 to need new rear brakes.Before I looked at this thread, noone I talked to had ever heard of such nonsense. I do at least half my miles on the highway. Rediculous.
I had my normal mechanic take a look and he showed me that one of the pads was totally gone while the other pad had normal wear. The Hyundai dealership is just giving me the runnaround.

If you are saying that on one wheel the pads have different wear it would appear to me that the caliber was not sliding corrrectly. You cannot fight city hall but that is a defect in the brakes.

Caliper guide...PINS... are not normally a wear item...particularly at low mileage however they do wear out ( I just replaced them and their bushings on our Dodge). I guess you are referring to the guide pins when you talk about caliper guides. They hold the caliper sides together and mount the entire caliper to its support. The typical symptom of worn guide PINS is tapered wear on the pads. Otherwise I cannot identify what the caliper guides you refer to actually are. So, while I am neither stupid or a Hyundai rep or I will tell you that disc brakes on any brand of vehicle all work on the same principal using similar parts and the same technology. I cannot tell you exactly why your brakes squeak nor if that squeak means that there is some malfunction of the brake system or not. but if the pads are not hung up (not retracting) causing them to be "on" whether you apply the brakes or not then the only squeak must be when you apply them and this my friend is pretty much a normal noise....well, maybe not normal but not an unheard of owner complaint either. Further, if this is what you are referring to, then other than this "squeak" being an irritant to you it isn't causing undue wear. I may be mis-understanding what you are trying to say and if so........ Oh and reviewing this series of posts I see that you do not have any specific complaint OR post prior to this reply and maybe don't own a Sonata either, just your 2 cents right?
