FUEL TANK DEVELOPED A LEAK WHERE FUEL LINE ENTERS THE TANK. *TR

20050809SEATS:FRONT ASSEMBLY:POWER ADJUST
DRIVER SEAT CAN'T BE PRESET FOR DRIVER 1 OR 2. OFTEN WHEN THE VEHICLE IS STARTED, THE SEAT GOES ALL THE WAY UP UNDER THE STEERING WHEEL. AT OTHER TIMES THE SEAT REMAINS SO FAR BACK THAT NOBODY CAN REACH THE GAS/BRAKE PEDAL. EACH TIME ANYONE DRIVES THE VEHICLE THE SEAT MUST BE RESET OR READJUSTED. GMC HAS BEEN TAKEN TO A REPAIR FACILITY MANY TIMES BEFORE THE WARRANTY WAS UP, BUT THE REPAIR CENTER SAID THEY HAD NO IDEA OR REMEDY FOR THIS PROBLEM. *JB

20030720EXTERIOR LIGHTING:HEADLIGHTS
I READ AN ARTICLE TODAY IN THE DETROIT FREE PRESS WHICH HAS PROMPTED ME TO WRITE YOU REGARDING HIDDEN LAMPS. MY COMPLAINT IS GENERAL, IN THAT THE AMOUNT OF "DAZZLE" FROM THE SCATTERED LIGHT IS GREATLY OBJECTIONABLE, AND MUST BE CONTROLLED. "HEAD-ON" VIEWING OS ACCEPTABLE, BUT SLIGHT OFF-ANGLE IS EXTREMELY DISTRACTING AND PAINFUL FROM THESE LAMPS. I WORK FOR A MAJOR AUTO COMPANY, AND HAVE SOME EXPERIENCE IN LIGHTING TECHNOLOGY. I WOULD PREFER IF NHTSA MIGRATE TO EUROPEAN REQUIREMENTS (CUT-OFF LINES) AND ENFORCE SOME TYPE OF ANTI-DAZZLE REQUIREMENTS FOR THESE LAMPS. ALTHOUGH ALLOWING A "WASH" IN FRONT OF THE VEHICLE ON THE ROAD, THE SIDE SCATTER I BELIEVE IS MORE DANGEROUS, POSSIBLE CAUSING OR RELATING TO ONCOMING DRIVER IRRITATION, ROAD RAGE, OR POSSIBLE ACCIDENTS. *AK
