“AS OF OCTOBER 20,2014 I HAVE YET TO SEE THE 1999 CHEVORLET S_10 LS OR THE 2005 CHEVORLET BLAZER S-T 4X4 MY HUSBAND HAS TESTED BOTH OF THESE IGNITION SWITCHES AND THEY ARE THE SAME. HE THEN CALLED A GM DEALERSHIP AND THEY TOLD HIM TO NOT PUT ANYTHING HEAVY ON THE KEY RING. WE ARE GETTING THE SAME SPILL FROM GM AS EVERYONE ELSE.WHY HASN'T THE S-10'S AND BLAZERS BEEN INSPECTED, THEY HAVE THE SAME IGNITION SWITCH FROM THE 1999 S-10 TO THE 2005 BLAZER 4X4 AND ARE VERY EASY TO KNOCK IN TO ACCESSORY POSITION. BECAUSE THERE HAS BEEN NO INFORMATION PUT OUT ABOUT OUR IGNITION SWITCHES, WE ARE HIGHLY CONCERNED ABOUT THE AIRBAGS AS WELL. WHY HAVE THESE VEHICLES BEEN OVERLOOKED NOT INSPECTED AND SILENCED? NOONE HAS SAID THE S10 OR THE BLAZERS IGNITION SWITCHES ARE SAFE. THERE IS ABSOLUTELY NO QUESTIONS IN OUR MIND THAT THE IGNITION SWITCHES ARE THE SAME AS ALL THE RECALLED VEHICLES AND FAULTY AND POSSIBLY THE AIR BAGS AS WELL. PLEASE,PLEASE LOOK INTO THIS I HAVE A DAUGHTER COMING OF DRIVING AGE AND WE NEED TO KNOW OUR VEHICLES ARE SAFE FOR HER TO EVEN STEP IN. *TR”
