“1999 Chevrolet s-10 Blazer: design flaw. The fuel gauge sending unit is made as one assembly with the fuel pump. The sending unit goes bad, but fuel pump is still in good operating condition. The cost of replacement is $600. The sending unit and fuel pump should be separate units. As my fuel gauge is not reading correctly, I must keep up with my miles driven by the odometer.”
NHTSA complaint #10066533, filed 2004-04, 89,000 miles“Gas sending gauge is irratic, causing me the inability to know how much gas I have. This is a very serious problem which I understand is very costly. According to the several mechanics that I obtained an estimate from this is not an isolated incident. They were all very much aware of this defect in the chevy Blazer.”
NHTSA complaint #10088446, filed 2004-08, 83,000 miles“The fuel gauge stopped working and/or started fluctuating. It didn't show how much fuel was left in the tank and still doesn't. I was on the interstate and ran out of gas, luckily I made it to the shoulder and wasn't hit. Now it still doesn't work and shows either a full tank or completely empty all the time.”
NHTSA complaint #10096043, filed 2004-10, 96,435 miles“No events just after I have been driving a while every day all lights including dash flicker and then when I shut off fuel pump won't pump up. This happens once a day and will not restart till next day.”
NHTSA complaint #10368538, filed 2010-12, 182,000 miles“Fuel gauge does not work. This occurred at about 40,000 miles. Ultimately has resulted in running out of gas twice. Apparently, the fuel sending unit and fuel pump are an integral system, costing anywhere from $400 to $600 to repair.”
