Kia Motor Spectra owners have reported 2 problems related to brake differential proportional valve (under the service brakes category). The most recently reported issues are listed below. Also please check out the statistics and reliability analysis of Kia Motor Spectra based on all problems reported for the Spectra.
The brake proportioning valve is leaking and the car is currently in the shop having this replaced. This is a 2003 kia Spectra. This part appears to be a manufacturer's defect as there are other complaints listed here and elsewhere. Has there been a recall as this is a safety issue that I cannot believe is limited to my vehicle. Also, the interior components started falling off within 6 weeks of ownership. The console lid broke, the caps for the gas release lever and the trunk lever have all come off numerous time. The car jack snapped the first and only time it was used to change a flat tire.

My daughter owns a 2003 kia Spectra [xxx] with a brake proportioning valve that started leaking about a week ago and is scheduled to be replaced. Are these valves defective because my other daughter with a 2002 kia rio [xxx] had the same valve replaced last year on her rio. I am concerned because this is a serious safety problem.
