Targettuning - regarding your assumption about previously owned Hyundais, please see my comment #24. Mine was brand new - 21,000 miles in 11 months, i.e., lots of highway driving and not much braking. I might add that I take meticulous care of my cars, driving them all over 100,000 miles. Furthermore, I usually do my own brake work. You mention neglect. I don't understand what could be neglect other than ignoring pad/rotor replacement when needed. My brakes seized and had to be replaced way too early. Good luck with your new Sonata. Your older models may have had less corrosive pad bracket material. It's the pad brackets that are the problem. Perhaps you live in the south, or somewhere where road salt isn't used? I would invite you to call Great Lakes Hyundai at 330-422-1212 and ask the Service Dept. what brake maintenance is recommended on a Sonata (and why). Last spring I was on vacation in St. Augustine when my power seat switch stuck (later became a recall). Hyundai of SA replaced it under warranty and I took the opportunity to ask them about Sonata brakes. They said they get a lot of northern Sonatas with seized brakes. Feel free to call them, too.

Please do not make this personal. You are free to accept or reject any information you find here at your discretion and you should be careful not to accept things posted "on the internet" at face value, absolutely. But if you aren't crazy about any particular member's posts, the thing to do is just skip them.
Thank you for your cooperation.

Tell you what targettuning, if you are really in the Army all I can say is God bless you and I hope you remain safe and thanks for what you do. As far as the brake issue, I realize all brakes are fundamentally the same, however there is something about the Sonata rear brakes that causes them to fail at a rate much higher than other vehicles in the Salt Belt. I've had enough cars in my life with rear discs and NEVER had them wear out or fail. I talked to a woman at Hyundai Consumer Relations who told me they couldn't do anything because the brakes are a wear item. I asked to speak to a Supervisor, waited on hold for 15 minutes, then she said Supv would call me back later. Still waiting. I did submit a problem report on the NHTSA site. I think a rear brake lockup is worthy of that. Hopefully everyone else with the problem will do the same because Hyundai is ignoring us.

I live in Savannah, GA and I'm glad we don't have that problem down here. I have an 06 Sonata LX with over 60k miles and I had my front brake pads replaced at 55k miles and the rear pads have not needed replacement yet. I hope everything works out for you.

Please note..I said "many, not all" may have been pre-owned and the context of my "neglect" comment was regarding those cars who may have been pre-owned since according to you there is a recommended brake maintenance. Also, I happen to live square in the middle of the so-called "rust belt" (in Pa.) I also concede that there may be a little known brake problem on rust belt cars and rest assured that if it is a result of material too prone to salt corrosion Hyundai will soon modify or otherwise correct it since from what I can tell they (Hyundai) seem to be "on top" of problems e.g your stuck power seat that became a TSB issue (probably this instead a recall). With that in mind I have little fear in buying a new Sonata or any other Hyundai product. In fact I wish I could justify (and afford) a new Genesis sedan!!!

Thank you, but although I have served (USAF, Vietnam war) I am currently a civilian working for Uncle Sam (Dept. Of The Army). As I posted recently I concede there may be a "material type" problem that renders these rear brakes more prone to quicker wear-out due to some type of sticking than other makes. But, if the rears are subject to this type of failure why not the fronts? I assume Hyundai utilizes the same materials and designs for all calipers/pads/and related hardware both front and rear. Not to mention these materials and designs are possibly used on other products within the Hyundai line up. This begs a further question....are these types of "failures" showing up on Sante Fe's, Elantra's or any other Hyundai product??

Target - I'm serious when I wished you good luck. Doesn't PA use only cinders? Anyway, when you buy your Sonata, do yourself a favor and check your brakes at about nine months, though. Regarding a Genesis, I would check timing belt replacement cost before buying one. The Sonata has a chain which never has to be replaced (I know - never?) but the Azera, for example, is a $1000 timing belt replacement every 60,000 miles - mostly labor. I don't know if the Genesis is the same engine but many are not aware of such maintenance costs before they buy. Don't get me wrong - other than the first premature set of rear brakes and a seat switch (dealer called it a recall as opposed to a recent stoplight bulb TSB), my Sonata has been problem free. I just drove it to FL from OH for the sixth time (those highway miles again) and got 33+ on the highway. The brakes definitely are a problem though. They are very noisy when turning and braking because of the earlier preventive maintenance. Regarding the noise, the service tech told me "that tells you the pads are moving and they're not sticking". Not sure I'd buy another one but haven't ruled one out. Maybe pre-negotiate the brake service! BTW - looking at comments for the Santa Fe and Kia Optima and Sorento, they have the same thing going on. Good luck and thank you for your service to our country. Back to PA - when did they start using salt?

I have lived in Pa all my life (62 years) with the exception of military and misc. short times spent in other states for schooling and various other reasons and it seems there hasn't been a time Pa didn't use salt. Depending where in the state you live (some areas get much more snow/ice than others e.g. the mountains and around Lake Erie) its use varies from merely a lot to ridiculous. Pa road crews would much rather salt than plow it seems. Worse yet, there is a combination of salt and small "rocks" so not only do you get salt corrosion but the rocks chip the paint allowing corrosion a foot-hold. Cinders? I wish..and now the state is using a "liquid pre-treatment" so corrosive it rusts the (large diameter) bolts holding the sprayer and other attachments to the truck off in one season. In fact after this happened to their trucks the state changed to stainless steel hardware. So, corrosion is a large issue here, now more than ever.
Regarding the Genisis..both the engines, the V-8 and V-6 use timing chains. Also, I was/am unaware of rear brake issues with other models in the line, will have to research more before shooting off. Still cannot figure why the front brakes don't suffer from these problems using the same materials and designs.

I agree. The only theory I can come up with is the front wheel leads and kicks up the spray that coats the rear wheel assembly. How's that for a shot in the dark?

I think you're mistaken on the timing chains. Azera, Sonata & Genesis all use Timing Chains & not belts. A timing chain doesn't need to replaced during the normal life of the car.
