2003 Chevrolet Chevrolet Truck

I PURCHASED CHEVROLET SILVERADO 1500 EXTENDER CAB NEW IN JUNE 2003. I HAVE APPROX. 165,000 MILES ON VEHICLE, THE DISC BRAKES ( ALL 4 WHEELS ) HAVE BEEN CHANGED 1 TIME AT ABOUT 110,000 MILES. EXCEPTIONALLY GOOD LIFE FOR BRAKE PADS ( THEY WERE STILL NOT WORN COMPLETELY OUT ) I HAVE NOW BEEN EXPERIENCING A BRAKE PEDAL FLUTTER/ SIGNIFICANT PULSATING JUST BEFORE VEHICLE COMES TO A COMPLETE STOP. EXISTING DEALER PADS ON VEHICLE ARE ABOUT 1/2 LIFE ACCORDING TO SERVICE TECH. GM TECH. "GUESSED" AT CAUSE LISTING 4 DIFFERENT POSSIBILITY'S FROM CORRODED LINES TO BOOSTER PRESSURE TO CALIBER FAILURE. NO INCIDENT AS OF YET. ALSO SIMILAR PROBLEMS LISTED WITH SPEEDOMETER AND GAUGES FORTUNATELY MINE EVENTUALLY RETURNED TO NORMAL AFTER ABOUT A WEEK. ALSO STEERING ASSIST CYLINDER WAS REPLACED BY DEALER FOR DEFECT THEN ISSUE WAS TURNED INTO PERIODIC MAINT. ITEM WHEN PROBLEM RETURNED AGAIN. *TR

WHEN I AM PULLING INTO A DRIVEWAY OR PARKING AREA, IF THE WHEELS ARE TURNED HARD TO THE LEFT OR THE RIGHT, WHEN STOPPING AND PUTTING THE TRUCK IN PARK, THE STEERING WHEEL LOCKS AND YOU CANNOT GET THE STEERING WHEEL UNLOCKED. THE KEY WILL NOT RELEASE IT OUT OF THE LOCK POSITION, EITHER BY JIGGLING THE KEY OR THE STEERING WHEEL. THIS HAS HAPPENED ON SEVERAL OCCASIONS. AS A RESULT, I AM FORCED TO HAVE THE ENTIRE KEY LOCK CYLINDER REMOVED AND REPLACED WITH A NEW ONE. I HAVE HAD TO DO THIS THREE TIMES. I HAVE BEEN STUCK IN PLACES THAT I HAVE PARKED, WITH THE WHEELS TURNED AND AM UNABLE TO GET IT MOVED UNTIL IT IS COMPLETELY TAKEN APART AND THE IGNITION KEY AND CYLINDER ARE REPLACED. IT HAS COST ME OVER 300 TO HAVE THIS DONE. IT IS DANGEROUS BECAUSE, ON OCCASION I HAVE STOPPED IN PLACES TEMPORARILY AND THEN NOT BEEN ABLE TO LEAVE AGAIN. I AM TIRED OF IT. I THOUGHT ORIGINALLY IT WAS A KEY PROBLEM, BUT HAVE FOUND, THAT I HAVE HAD TO REPLACE THREE IGNITIONS ALREADY, I BELIEVE IT TO BE A DEFECT IN THE STEERING COLUMN, STEERING LOCK OR WHEEL TURNING PROBLEM. PLEASE HELP ME GET THIS RESOLVED. THANK YOU. *TR

I PURCHASED A USED 2003 TAHOE AND I HAVE HAD TH TRUCK FOR 6 MONTHS. I HAVE BEEN HAVING PROBLEMS WITH THE FRONT END STEERING. I HAVE A HARD TIME KEEPING THE TRUCK ON THE ROAD WHEN HITTING BUMBS ON THE ROAD. I HAVE BROUGHT THE TRUCK IN NUMUROUS TIMES TO THE DEALERSHIP TO GET IT FIXED. THE FIRST COUPLE TIMES THEY LUBED THE STEERING SHAFT AND SAID IT SHOULD BE OK. THEN ON THE FOURTH OR FITH TIME THEY CHANGED THE PTIMAN ARM, AND CHANGED THE ARM KIT. THE MECHANIC TOLD ME HE FIXED 90% OF THE WANDERING ON THE ROAD. BUT THE PROBLEM STILL EXCISTS. I FEEL UNSAFE TO DRIVE FOR MYSELF AND MY FAMILY.
