We are experience a continuing groaning noise when bringing our 2004 KIA Sedona automatic to a stop. We have been back and forth to our local dealership with no joy. We have had the front discs and pads replaced recently, thinking this would cure the problem. No. Every time the dealership takes it out for a test drive it does not happen - typical! We did find it was worse when the vehicle was full. This time we have been told that it "could be normal because the brakes Kia put on the Sedona were not efficient enough for the weight". Have you heard of this before or do you know what could be causing the problem? We have had this noise for over 12 months now and really do not want it when we go to Spain next month.
