PLEASE INVESTIGATE THE POTENTIAL OF FIRE/EXPLOSION CONCERNING THE FUEL TANK SENDING UNIT (IN OLDER MODEL G.M. VEHICLES) AND THE POSSIBILITY OF A "DIRECT SHORT" TO IT'S WIRING. I BELIEVE THIS COULD BE A SERIOUS SAFETY ISSUE. *AK
20040928ELECTRICAL SYSTEM:WIRING: REAR COMPARTMENT/TRUNK
THE LOCATION OF THE WIRING HARNESS, IN GENERAL, AND ITS LOCATION TO THE FUEL TANK IN A REAR END ACCIDENT WOULD MASH THE HARNESS BETWEEN THE BUMPER AND THE FUEL TANK. IF RUPTURE OCCURS THEN THE IGNITION SOURCE WOULD BE PRESENT, RESULTING INTO AN EXPLOSION. *AK

I HAVE A COMPLAINT REGARDING BOOSTER SEATS AND THE INABILITY TO PROPERLY SECURE MY 50 LB FOUR YEAR OLD. SHE IS TOO BIG FOR A 5 POINT HARNESS CAR SEAT (40 LBS) AND THERE ARE NO SHOULDER BELTS IN MY 1986 SUBURBAN TO USE A HIGH BACK BOOSTER SEAT. I CAN NOT COMPLY WITH THE NEW CALIFORNIA LAW AND AS A LOW INCOME FAMILY WE CANNOT AFFORD A NEW SUBURBAN FOR OUR 5 CHILDREN! WHAT ARE WE SUPPOSED TO DO????
