I bought my used 2000 Chevy Blazer 4 door 4WD this year and noticed that the fuel gauge was erratic. When filled up it reads full but after driving over 150 miles the fuel gauge jumps around from empty to full continuously. I've read several reviews at this site and believe Chevy has a major defect in the fuel sending unit for this vehicle that they need to research and correct. I believe a recall for this problem is in order.

I bought a 2000 Blazer in 2002. I took my vehicle overseas in 2003. Much to my surprise, the gas gauge stopped working properly one day in 2004 causing me to run out of gas on a major international interstate. I took it to the dealership when I came back to the states only to be told, that something was wrong with the fuel pump. Not only that, the module also has to be replaced because the fuel pump and module comes as a unit and you cannot replace the fuel pump without replacing the module. I am being told I have to pay $950 to have this problem fixed. I know I am not the only one with a Blazer who is having this problem. GM has failed time and time again to acknowledge this as a manufacturer problem and people are losing money because of it. If I have to pay $950 out of my pocket to fix this problem, this will be one unhappy, loyal customer GM has lost because I will make sure that no one I know ever purchases a GM vehicle again.

Owns a 2000 Chevrolet Blazer ZR2 with 68000 miles. The heater blows cold air only. The alternator has been replaced at least twice. I replaced it once, and previous owner replaced it once. Battery has been replaced at least twice. All ball joints replaced at least once to my knowledge. Fuel gauge broke before 50000 miles. Seat handle on passenger's side broken before 50000 miles. Tailgate won't open. Passenger side windshield wiper only moves half the time. That is all that I can recall right now.

I have a 2000 Blazer with 58,000 miles and the fuel gauge does not work properly. I have heard dealers and mechanics say that it is common problem with Chevrolet. I would like to know if they plan to address the issue. Also, my locking rear differential does not work. My brother had it replaced twice under warranty on his 2004 Z71.

- Little Chute, WI, USA

Ball joints upper and lower replaced at 40K and 100K miles. Will be needing to be replaced again very soon at 140K miles. The replacement at 40K was a total failure of passenger side ball joints to wit: Vehicle was incapacitated as wheel was left 'bent'. fuel gauge fluctuated wildly if less than 1/3 tank of gas. Fuel pump failed.

Radley Chevrolet did not provide us with a recall notice on brake lights not working. We have had problems with our 2000 Chevrolet Blazer from the start. We have been now told that the idler arm on the car is a safety hazard. We also had the fuel gauge go out. How often do these components go out. Can you tell me anything about the idler arm and is there any recalls for this item.

The fuel guage in my 2000 Chevy Blazer stopped working causing me to run out of fuel with my 4 year old son in the vehicle. I also had a 1996 Chevy Blazer and the fuel guage stopped working (my father now owns this vehicle). I contacted Chevrolet and they claimed that they have no reports of fuel guages that stop working. A very close friend of mine who worked for Chevrolet for 20 years told me that this is not true. Apparently the fingers on the sending unit were falling off causing the guage to not work.

Contact states the fuel gauge is not consistent in the readings. It does not measure the gasoline correctly. A mechanic stated there was a problem within the electronic wiring that deals with the computer to the fuel gauge. The vehicle has not been serviced for this problem.

- Greensboro, NC, USA

The gas gauge fluctuates from E - F when my tank is only half full. The only way I know how far I can drive is to zero out the trip odometer when I fill the gas tank. This vehicle had has approximately 55K miles on it - too few for this kind of problem.

I just purchased a 2000 Blazer ZR2, when the gas gauge hits 3/4 tank, the gauge will bounce back and forth from empty to full. I never know how much gas I really have, which could cause a real safety issue to myself, let alone the hundreds of dollars it would take to replace the fauly sensor. I've found that lots of GM consumers also have this problem, which I feel GM should be responsible for replacement. My vehicle only has 56000 miles.

2000 Chevy blazerfuel guage doesn't register properly below 1/2 full. Often fluctuates below 1/2 tank from empty to full or in between. Only 25000 miles, just out of warranty (expired June 2004).

- Bangor, ME, USA

The fuel gauge almost never reads less than 5/8 full. Every couple of months, it will show empty (when empty), monentarily, but them bounce back to 5/8 full. The dealer replaced the gauge cluster twice under warranty, and it failed again in a short period of time. I met another person who bought a 2001 with the same problem.

The fule sending unit went out and the transmission went out at 50,000 miles.

- Mount Sterling, IL, USA

Fuel guage fluctuates between empty and full anytime fuel tank is less than half full. I am worried about possible voltage problems in the tank.

- Bethlehem, PA, USA

The fuel sending unit is operating erratically, causing the gas gauge to be inaccurate. The cost of repair is $400 for a new sending unit/fuel pump and $200 for labor! I have heard from other GM owners that this is becoming a common problem. GM will never get my money for a new car again if they don't own up to this problem.

- Rosamond, CA, USA

Gas gauge reads full with less than 1/2 tank. I also own a 1997 S-10 with the same problem. Reset the trip odometer after fill-up with both of them.
