MY TRANSMISSION WOULD NOT SHIFT OUT OF SECOND GEAR. I TURNED IT OFF AND BACK ON AND IT DID NOT CLEAR. I GOT A "PRE-SAFE UNAVAILABLE" MESSAGE. I DID SOME RESEARCH AND LEARNED THIS IS A "TRANSMISSION CONTROL MODULE" FAILURE. IT IS VERY UNSAFE IN THAT THE CAR CANNOT KEEP UP WITH TRAFFIC AND IS A DANGER TO MYSELF AND OTHERS. *TR

WHILE DRIVING THE CAR THE FRONT END DROPPED MAKING IT VERY DIFFICULT TO STEER. HAD TO SLOWLY MOVE TO THE RIGHT LANE WHILE TRAFFIC IS GOING 70. THIS COULD HAVE KILLED ME.
WENT OUT TO THE CAR TO GO TO THE PHARMACY TO GET MY ASTHMA MEDS AND THE CAR WAS DOWN ON THE GROUND,TOTALLY DEFLATED SHOCKS. START CAR AND RISES TO HEIGHT BUT SINKS WHEN CAR IS OFF, THIS IS A DANGER IF DRIVING ON THE HIGHWAY AT 55 MPH, I HAVE A WIFE AND A YOUNG SON. I FEEL THAT THE DEALERS SHOULD RECALL AND FIX THIS PROBLEM CORRECTLY, AND NOT HAVE PEOPLES LIVES IN DANGER ON THE ROADS OF AMERICA, ANY HELP WOULD GREATLY BE APPRECIATED. THANK YOU , A CAUTIOUS DRIVER. *TR
