Beginning in February, noticed brake dust smell coming from the driver's side rear wheel. Upon inspection found that the parking brake linkage was sticking in the "on" position when the parking brake lever was released. At the same time experienced a small pull to the left and a noticeable loss in M.P.G. a trip to the local Hyundai service department confirmed that the right rear caliper was sticking. I was told that the problem was only for the "defective" drivers side and it was a manufacturing problem. The repair happened in March and seemed to be working fine at that time. In April, a "bang" sound stated to be heard when releasing the parking and driving away after sitting over night. This "bang" sound stated as an only once a week problem to now an every day problem. I have looked and confirmed that now "both" rear calipers are sticking upon releasing the brake in the morning. The problem is still happing and now braking while driving is starting to become inconsistent. Sometimes the car brakes fine, other times the car seems to have a noticeable "weak" braking function (increasing stopping distance). Upon looking up problem on the internet, I discovered that many other owners of 2012 Velosters are having the same problem. The problem seems to be for owners in northern part of the North America where dirty/ salty roads are seen (I live in Vermont). My concern is that the braking system was not design to deal with these conditions and corrosion is affecting the function of the rear braking system. I'm also concerned that Hyundai motor company is not coming up with a solution and is just replacing the same defective caliper with another one.
