3 Brake Drum Wheel Cylinder problem of the 2011 Hyundai Sonata

Failure Date: 01/28/2011

Coming out of side street, going about 5-10 mph. Depressed brake to stop/slowdown and car (2011 Hyundai Sonata purchased in February 2010) just kept on going into intesection and up the road. Kept pressing pedal all the way to floor and car still kept going until it glided to a stopped. Travelled about 100-150 feet with no brakes and had use horn a few times to warn other drivers. After this I moved again and brakes worked fine. Very scary. . . Went out into a very,very busy street. Fortunately I hit no one and no other cars hit me. Will call dealer to report it and ask for further advice. Perhaps ice, snow, sand, etc. Got into pads/cylinders and temporarily seized the brakes? don't have VIN with me will report it later.

4 Brake Drum Wheel Cylinder problem of the 2007 Hyundai Sonata

Failure Date: 06/29/2009

2007 Hyundai Sonata - 4 cylinder rear brakes noticed smell & heat coming from rear wheels after car was stopped. Have also noticed that fuel mileage has been poor for the last several months. Suspected park brake sticking, but took to dealer to investigate. Their investigation came back that rear brakes were sticking and rear brake pads worn out after 27,000 miles. Recommended I have the rear pads & rotors replaced, and should have a "brake service" done where they disassemble the brakes, clean and reassemble. Brake service was done and rear brake pads were replaced. Refused new rotors based on a 2nd opinion that they were fine. I asked service manager why this would be necessary with so few miles on the car. I previously owned a 2004 mazda6 with rear disc brakes. I bought it new and traded it with 70,000 miles on it, having spend $0 on the brakes. His response was that all Hyundai Sonatas experience problems and unless annual brake service is performed, I will have problems with the rear brakes sticking. I view this as a manufacturer defect. Hyundai charges me for the brake service, and since I did not have it done during the first year of ownership, my rear brakes were sticking on , causing my poor mileage and a rear brake pad replacement. None of this work was covered under warranty, and I am now out approx $500 for work performed on my car, not to mention the fact that I will now need to spend money each year to have a "brake service" performed. A quick check on message boards on the internet revealed that many people are seeing the same problem. This should be rectified by Hyundai in the form of a recall. I should be reimbursed for the money I have spent, and an improved design should be implemented (such as on my Mazda).
