| The following is an email that i sent to the service department i recently went to for recurring brake/caliper issues on this vehicle. as you know i was in yesterday (buerkle hyundai white bear lake, mn @ 8:48 am invoice 183543) with my 2008 hyundai sonata with left rear brake issues. it seemed like the left rear caliper may be sticking. as i explained when the car was dropped off yesterday (2/5/13), we had just replaced both rear brake pads and rotors and the car only had 29,975 miles when the brakes and rotors were replaced on 12/22/2012. i brought in the previous brake pads and rotor for your inspection from the rear drivers side of the vehicle. the side that is currently having issues. it clearly showed the brake pads were completely gone and the rotor was scraped and ruined. this was shown to the service advisor helping me, brian coyle. i have attached, just a few out of several, websites for your review to show this is a known problem that has received many consumer complaints. http://www.arfc.org/complaints/2008/hyundai/sonata/service_brakes_hydraulic/problem.aspx http://www.sonatabrakedefect.com/index.php/sonatadefect/sonatacomments.html http://www.carproblemzoo.com/hyundai/sonata/brake-disc-caliper-problems.php http://www.aboutautomobile.com/complaint/2008/hyundai/sonata/hydraulic+brake as you can see, this issue, definitely, needs to be addressed by hyundai as well the hyundai certified service department locations. the consumer should not be responsible for repair and payment of a known manufacturing defect, one time, let alone over and over again for the same issue. not to mention, brake issues like these and to this extent of needed repair at such low mileage. i really should not have been charged for a repair or for lubrication to brakes, etc, when the same thing was done to these brakes a few weeks ago. | |||

| My rear brake calipers were frozen/ corroded into the pads. the rear brakes were inoperable. this could have effected the ability of the car to stop effectively. the dealer said they would not replace unless the caliper was leaking. it was corroded at only 39,000 miles and 3yrs after bought. *tr | |||

| Pulled off to the side of the road. snow on the road. started to move out to the road again when i noticed a loud grinding coming from the rear brakes. made it home and took the car to the shop where i bought it, healy hyundai in beacon ny. rear brakes down to metal and rotors going. they resurfaced rotors and said it was normal wear and tear. no other explanation. i did not appreciate this because even not having not much of a mechanical background, i never had trouble like this with brakes this early on and i have driven many a car and many miles. the car has 36,014 miles and heaely said the front brakes have at least a year to go. someone at hyundia needs to get to the bottom of this before this becomes alot worse. please i hope someone looks into this. also the dealers need to be honest with people and not blame an perceived defect in my opinion with the brakes on the driver. i have children and don't want the brakes to fail. please look into this. *tr | |||

| I am driving a 2008 hyundai sonata and had my rear brakes deteriorate to nothing with out any warning. they were to the point where it was metal to metal and i had to replace my brakes and my rotors. the scary part was that the sounds metal to metal were not constant so if you did not know better you might debate on what the problem was. *tr | |||

| Grinding of rear brakes beginning at 37,000 miles. car is driven all highway miles. brought in for service and mechanic was shocked to see pads were gone and rotors worn beyond repair. he said front brakes should usually go first. hyundai claimed pads should be removed and cleaned every 15,000 miles. assuming a customer was denying the brake problem due to the low miles the loss of brakes could lead to a serious accident. brakes and rotors will be close to $400 for repair. *tr | |||

| The braking system on this vehicle is poorly engineered and extremely frustrating to the car owner. after 16,000 miles, my rear brakes began squealing. after inspection, it was determined that the back brakes are sticking on and grinding off against the rotor. this is a reoccurring problem that can not be fixed, with multiple replacements the only choice. in the four years i have owned the vehicle, i have gone thru 5 sets of brake pads and 4 rotors, with no end in sight as long as i keep this car. | |||

| Rear brakes on my sonata started grinding at 25000 miles. contacted hyundai headquarters by email and they stated the brakes were out of warranty and no recall on this problem. i was informed by them to take it to the hyundai dealer. since this should not happen at this mileage i had taken it to my mechanic who is state certified. hyundai needs to do a recall on this safety problem. i have kept the email response that hyundai headquarters sent tome. | |||

| Purchased demonstrator car with approximately 2,500 miles for normal use. rear disk brake noise at 15,976 miles required both rear brake pads and rotors to be replaced under warranty. same problem happened again at 33,356 miles, again requiring replacement of pads and turning of rotors (this time it was not covered - considered normal wear items). once again, at approximately 52,000 miles, loud grinding from the left rear brake revealed that both inner and outer pads had been totally scrubbed off with light metal to metal contact, while the right rear pads still had greater than 50% of original pad thickness. the caliper slides operated smoothly and were well lubricated and sealed, and the pad slides were dirty with brake dust, but not corroded or blocked with dirt. the pads appeared to have been exposed to high heat. i replaced the pads to finish my trip and upon return it was apparent that the new pads had been dragging as evidenced by a strong smell and glazed appearance. it does not seem normal for this condition to happen - there was no grinding or abnormal noise observed during the most recent event, until pulling into our destination, when it was very loud. appears that the caliper or caliper piston is sticking to keep the pads in contact with the disk, thus overheating and challenging the brake pad life. this seems to be only on the left (driver's side) caliper. hyundai discussion forums have indicated this is a common problem that hyundai is not formally addressing. i will take the car to the dealer this week, but wanted to register with nhtsa since it is a brake issue with safety implications. | |||

| When i bought a new 2008 hyundai sonata, i soon experienced a squelling sound from the rear brakes. the dealership serviced the brakes. they said it was the shims causing the brakes to sieze and keep from sliding properly. within 30,000 miles the rear brakes were worn out. i now have 54,000 miles on the car and the rear brake pads are worn out. i discovered from my mechanic that this model is known for a premature wear problem with the rear brakes. the pads seized in place unable to back off the rotor. i'm prompted to notify you due to the many postings of this issue on the internet. i'm not sure if it is a weather concern with corrosion or a design flaw in the caliper. | |||

| I have been concerned about the rear brakes due to the numerous complaints on mycarstats.com. often when i get the car serviced by the dealer i have mentioned that they should check the rear brakes. this time was the 45000 mile service and i brought a printout of the 26 existing complaints. the service manager assured me that they always check and clean rear brakes, calipers, rotors, etc to prevent an early failure. shortly after leaving the car, the service manager calls me to say that indeed the rear brake pads were worn out and needed replacing. i told him i thought that it should be under the bumper to bumper warranty because it was a known defect in these sonatas. he said brakes only had a 1 year warranty and i would have to pay. there was no sound or warning in advance. if it wasn't for the mycarstats.com website, i would have never known to keep asking. the front brakes are fine and have not yet been replaced. driving is mostly highway. is there a class action suit for this yet? | |||

| Took car to dealer for annual state vehicle inspection and to have chirping noise from brakes checked. rear brake pads were at 3/32; min allowed is 2/32. front pads ok at +7/32. replaced rear pads, machined rotors. mileage was 23,226; car purchased feb2008 and was regularly serviced at dealer. dealer sa advised that pad wear was normal and that 'on this model the rear brakes always wear faster'. when this was disputed the sa said that corrosion on caliper did not allow pads to withdraw and that constant contact wore out the pads. when asked about warranty coverage sa said that brakes are only covered for 12 months. subsequently noted that on side of car with sticking caliper that the paint on both steel wheels has peeled and wheels have rusted. tires have been rotated, front-to-back, several times since new. possible that excessive heat from dragging pads overheated wheels and damaged paint. also possible that there was excessive heat to wheel bearings. will have this checked at next service, or sooner. this premature rear pad wear is not normal for hyundai. also, presently driving a 2001 elantra that went 60k+ before needing brakes. never owned any car that had rear brakes wear before front. the number of complaints registed indicates that this is a design/material issue that needs correcting before someone is hurt. | |||

| No failure occurred. the problem was detected before failure. i had the brakes checked at just under 45,600 miles expecting to have the brake pads replace. inspection showed that the rear brake rotors were made of defective metal which corroded and pitted badly. it destroyed the outer part of the brake pads so they did not make contact with the rotor. less than one half of the brake pad was providing braking ability. the rotors had to be replaced on the rear wheels as well as all brake pads on all 4 wheels. the brake pad replacement is expected maintenance. the rear wheel rotors were defective parts. | |||

| Tl-the contact owns a 2008 hyundai sonata. while driving approximately 20 mph, the contact engaged the brake pedal and heard a metal to medal loud screeching noise. the vehicle was taken to an authorized dealer where they informed that when the vehicle was produced the manufacturer did not lubricate the pistons properly; and the quality of the lubricant was insufficient. the rear rotors were replaced at the owner's expense. additionally, the owner?s manual instructed that the brakes be diagnosed every 15,000 miles, and if the brakes lubrication was not functioning properly then the calipers would need to be replaced. the contact stated the information provided in the manual was not communicated to him at the vehicle?s time of purchase which was a significant concern. the failure mileage was 22,000. the vin was unavailable. js | |||

| I have a 2008 hyundai sonata and had to replace my rear brakes at 24,000 miles. my dealer said that it had something to do with the calipers sticking and this caused my rear brakes to wear prematurely. my dealer also indicated that this is a hyundai problem and they see this a lot with these cars. i contacted hyundai and informed them of this issue, and they were very rude to say the least with regard to their response. they clearly took no responsibility for this issue and for the most part lays the blame on the driver and the driving conditions. under no circumstances should the rear brakes require replacing at such low mileagel. there are many other complaints listed here where other owners of these cars have had the same problems, yet no investigation is being launched and hyundai clearly refuses to take responsibility for clearly substandard braking systems. | |||

| Tl-the contact owns a 2008 hyundai sonata. the contact stated that she heard noises from the brake area. the vehicle was taken to an authorized dealership where the brakes and rotors were replaced. the contact called the manufacturer who stated that the brakes should be inspected every 15,000 miles but offered no further assistance. the current and failure mileages were approximately 27,100-bk | |||

| At 10k miles rear brake rotors were glazed from sticking brake pads; rotors were machined and brake pads replaced. at 26.8k miles the rear brakes were metal to metal and brake pads completely worn due to drivers side brake pad being siezed into rotors (dealers language). dealer attributed brake failure to increased corrosion due to our maine location. none of the other vehicles we have had exibited these problems. this is a safety issue in that i have been operating the car for an indeterminate time with no rear brakes. the defect was discovered during a normal tire rotation. i suspect hundai encourages tire rotation at every service interval in order to have an opportunity to examine rear brakes. | |||

| Rear brakes sticking on. first occurred at 35,000 miles and dealer notified me that the brake pads needed replaced, but upon inspection i saw that only one pad was worn to the metal, and the others were at > 50% life. i replaced the pad but the caliper and slider design is defective and the failure happened again at 40,000 miles. this time the car began jerking and suffered loss of brake performance as the indicator, along with noise, smoke, and odor. the hyundai dealer (mike miller in peoria, il) would not fix the problem under warranty, instead saying it was a normal wear item. | |||

| Began hearing a dragging noise in the rear of the car and thought something was dragging underneath looked and saw nothing. got home and noticed that there was significantly more brake dust on the passenger rear hubcap than all the others. after further inspection it appears that the pad is completely worn because the brake is locking and then not releasing when it should. i have done quite a bit of research and noticed that many other people have had very similar complaints about this model year and malfunction. the common trend is low mileage so this is not a driver issue. this will ultimately result in the replacing of the brake pads and rotors at the very least. the car is currently with the dealership so they can tell us everything that is wrong. *tr | |||

| Recently brought my 2008 hyundai sonata in for a free inspection by my dealer. my brakes were inspected and my rear brakes were found to be 70% worn and the pads, etc... were frozen resulting in premature wear!!! my front brakes are only 50% worn. my service manager said that this is typical for hyundai sonatas of this year but no financial remedy came from my dealer. i had to pay to have my brakes unfrozen and was told that within the next 3 months i will need to have new rear brakes put on. of note, my car only has 24,000 miles and my rear brakes should not have worn out this soon and certainly not before my front brakes. hyundai needs to get on the ball here and issue some type of recall. this is a major safety issue - i have a child that rides in this car constantly. | |||

| Car had 19,000 miles on it, i bought it new. grinding noise from rear drivers side wheel took it to dealer and was told that the rear caliper was not releasing which ruined the brake pads and rotor. told the car was not safe to drive. the rotor, caliper and pads had to be replaced. dealer covered the cost. never had brake problems with any other of the other cars i owned. my miles are highway miles and i do not have to use the brakes as often as i would in the city. *tr | |||

| Premature wear of rear brake pads on a 2008 hyundai sonata. rear brake pads were completely gone at 35000 miles. my wife had brake failure while on the interstate. removed wheels at home and found calipers were digging into rotors because of complete erosion of brake pads. called dealer he said it has been an ongoing problem with this car. not sure why, hyundai offers no explanation or suggestions either. replaced pads with new ones, will wait to see what happens. i will inspect every 10000 miles to determine extent of future wear on the brake pads. front pads were at 8/32 rear pads were 0/32.. pistons were clean on the rear and appeared to be working fine, both rear pads were gone equally. *tr | |||

| 2008 hyundai sonata with only 12,600 miles, while driving with 2 small children heard loud noise from back of car while taking a turn. brought to dealer and was told needed new brake pads due to rust on the rotor. didn't have them do the work as the cost was large. brought to our own mechanic who showed us the left rear brake pad was down to metal but the right was normal small wear. he called hyundai dealer as this didn't seem normal to him either. warranty only covers up to 12,000 miles so we were out of luck. hyundai goes on in every commercial about safety and when i think of a car brakes are the most important safety feature there is. *tr | |||

| I purchased my 2008 hyundai sonata in february, 2008 brand new. since day one, i have had problems getting the car out of the park position. i took it to my dealer for service and they did replace the brake switch once, but this is still occurring daily and it is frustrating. often times it takes 5 or 6 tries with my foot firmly depressed on the brake pedal for my vehicle to get out of the park position. yesterday morning, i was stuck at a drive up window because i had the car in park and could not get it out again - took about 5 tries to get it into drive.*tr | |||
