Navigational (global Positioning System) Gps problems of the 2011 Kia Motor Forte

Problem began 2/14/2011 (purchase) and continues. There has been a problem with these “high frequency” sensors as noted on a sheet dated 9/22/08 provided by the kia engineer. These devices are prone to set off the high frequency sensors which gives me a false reading. With this being the case, then why are these high frequency sensors installed in vehicles? my sensors are like the little boy who cries wolf…. When they illuminate repeatedly on and off, I just ignore the light and wait until I turn off the car or wait it out…whichever turns off the light first. The sensors are not fully functional because since they are so sensitive to radio frequency waves as stated by the kia engineers, then NHTSA has the obligation to have kia remove and replace with sensors that are not sensitive (as similar to my Ford focus’ which illuminated and went off when air was put in the tire(s)). Otherwise, having malfunctioning sensors and under-inflation of tires can reduce vehicle safety, reduce tread life of tires and reduce fuel economy which defeats the main purpose of a sensor. From the 9/22/08 info sheet: “ pitstop: outside radio frequency (rf) affecting tpms operation kma has received several inquiries regarding the tpms light on with or without stored diagnostic trouble codes in memory. The following listed components/conditions may cause the control unit and wheel sensor communication to be interrupted and may cause multiple dtc’s. • some cell phone chargers • some laptop computers • exciter tool connected while driving the vehicle • some portable navigational devices (gps) • aftermarket rke, burglar alarm, remote start systems • power inverters, portable mp# players • ham radio equipment • high tension power lines and radio station towers • vehicle anti-theft locating devices • portable dvd players • incorrect instrument cluster – part application not correct”.
