1997 GMC GMC Truck

I AM PROMPTED TO REPORT TO THE NHTSA AFTER READING ABOUT YOUR INVESTIGATION MENTIONED IN A MAGAZINE NAMED SPORT TRUCK OF JANUARY 2000,VOL 13,NO.1,PAGE 19 IN WHICH 1997 TO 1999 CK PICKUPS ETC; ARE SAID TO STEER UNEXPECTEDLY INTO OTHER LANES;CAUSING 4 CRASHES.JUST TO LET YOU KNOW ,MY CANADIAN TRUCK AND MY INLAW,S TRUCK BOTH EXIBITED THIS STEERING PROBLEM.MY DEALER CHANGED OUT AFTER TESTING IT,S VOLTAGE RESISTANCE,THE EVO STEERING WHEEL POSITION SENSOR CORRECTING THE UNNERVING SENSATION OF OVERSTEER AT HIWAY SPEED IN A TURN.THIS SENSOR IS SAID TO CHANGE HYDRAULIC ASSIST OF THE STEERING DEPENDANT ON VEHICLE SPEED AND STEERING WHEEL POSITION TO EASE FOR PARKING.A DEFECT IN THIS SENSOR COULD CAUSE AN ANWANTED OVERSTEER EFFECT WHEN STEERING INPUT EFFORT IS EXERTED TO MAKE A TURN AT HIGHWAY SPEED OR EVEN WHEN TRYING TO MAINTAIN A STRAIT AHEAD DRIVE ON A CROWNED HIWAY.WHEN I DESCRIBED THE FUNNY STEERING FEEL TO THE DEALER,I THOUGHT A WHEEL ALIGNMENT WAS IN ORDER,NOT KNOWING THERE WAS A SENSOR INVOLVED.THE MECHANIC WENT STRAIT VOR HIS VOLT METER AND THE SENSOR UNDER THE DASH ON THE COLUM,LEADING ME TO BELIEVE THAT TO THEM,THIS IS A COMMON OCCURANCE.ON AN EXTENDED WARRENTY THAT I PURCHASED,A $100.00 DEDUCTABLE IS INCURRED FOR THIS REPAIR.PLEASE FEEL FREE TO INFORM ME AS TO WHAT YOU FIND;I WILL FREQUENT YOUR WEB SITE AS WELL.SHOULD THIS BE A RECALL? I THINK SO. THANKS. *AK
