THE AIR BAGS DID NOT DEPLOY DURING A 35 MPH FRONTAL COLLISION. *NLM

WHILE DRIVING THE FOURTH GEAR OF THE AUTOMATIC TRANSMISSION JUMPED. THE DEALER INSPECTED THE VEHICLE BUT COULD NOT DUPLICATE OR CORRECT THE PROBLEM. *NLM

THE VEHICLE SHIFTED INTO 4 LOW WITHOUT WARNING. *JB

THE PASSENGER SEAT DOES NOT ALLOW CONSUMER TO RIDE WITH THE AIRBAG ON. YOU HAVE TO BE 120LBS OR OVER BEFORE THE AIRBAG WORK PROPERLY. PH

THE HIGH-BEAM INDICATOR LIGHT (BLUE) IS EXTREMELY BRIGHT AND IS SO AIMED AS TO SHINE DIRECTLY INTO THE EYES OF THE DRIVER. THIS CAUSES A SIGNIFICANT DISTRACTION DUE TO THE LIGHT SHINING DIRECTLY AT THE LEFT EYE AND ALSO GREATLY REDUCES THE VISIBILITY THROUGH THE WINDSHIELD DUE TO THE ADDITIONAL LIGHT. THIS HAS BEEN REPORTED TO GMC VIA THE DEALER AND I WAS TOLD THAT THE LIGHT IS PART OF A CLUSTER AND THERE IS NOTHING THAT CAN BE DONE TO FIX IT. THIS LIGHT IS A SIGNIFICANT SAFETY HAZARD AND NEEDS TO BE REMEDIED. DT
