Three problems related to tank assembly have been reported for the 2000 Chevrolet Blazer. The most recently reported issues are listed below.
Fuel gauge fluctuates wildly between full and empty when tank is less than half full. If you look it up the GMC jimmy which uses the same fuel system has the same customer complaints. You never know how much gas you have in the tank. This caused me to run out of gas on a interstate highway in the middle of rush hour and I was unable to pull over to the side because of traffic. Luckily no one ran into me, but it did create a bad traffic problem. Gm refuses to admit this a problem but the mechanics I've talked to say this is a problem they have to repair all the time. This vehicle should be recalled before someone gets injured or killed.
I own a 2000 Chevrolet Blazer, 4 dr. Lt model. The fuel gauge is erratic and will bounce all over the range, whenever the fuel level is at approx. 1/2 tank or less. This has caused me to run out of fuel, on the highway, because I thought that there was fuel in the vehicle; but the gauge was not registering correctly. The local dealer wants over $900. 00 to fix this problem. In doing some online research, this appears to be a very common problem, and gm should issue a recall and fix this problem.
We purchased a brand new 2000 Chevrolet lt Blazer and now the fuel sender will not work properly. Therefore, we do not know how much gas we have in the tank. Per my brother's inquires on a website he found out that there have been numerous other people that have had this problem and was told by a gm technician that this was a defect in this make/model, they are aware of the problem. I think it should be a recall and the consumer should not have to pay to have this repaired since they know it is a defect and is costly to repair especially since the vehicle is not very old!.
