2002 Chevrolet Trailblazer: wrong fuel gauge reading

Filed Mar 27, 2017 · Electrical · 185,000 miles · DE

My entire instrument panel is inoperative. I am unable to tell my speed, fuel level, oil level and pressure, temperature, whether or not my high beams are on or off, or whether the cruise control is engaged. I use my GPS as a speedometer and have run out of gas on high-speed limited access highways 4 times. The dealer wants nearly $500 to fix this although it's a common problem (see google). Running out of gas on the interstate is a matter of life and death. I've asked to speak with a zone rep and gotten nowhere. The two photos were taken on 3/9/2017. One with the engine running and one with the engine off. There's no difference!!!

Tl* the contact owns a 2002 chevrolet trailblazer. While driving approximately 35 MPH, the transmission shifted out of gear and the anti-theft lock and battery warning indicators illuminated. The vehicle was taken to a dealer where it was determined that the transmission needed to be replaced. The vehicle was repaired. The contact also mentioned that the fuel gauge displayed an inaccurate reading when the fuel tank was full. The manufacturer was made aware of the failure. The failure mileage was approximately 143,000.

Faulty gauges. Gauges sometimes work, sometimes don't. When not working, service engine light comes on first and then nothing works on dash panel except signal lights. When it does work, normal startup of lights. Being the odometer is digital, no way of knowing how many miles I have gone which goes hand in hand with gas gauge not working so not a clue how much I have.

Smelled fuel thought it wasn't burning the fuel correctly. Had mechanic look over vehicle and he found that the gas was leaking from the gas tank area. Without removing the thank he said it could be a hole on the top of the tank or the fuel sending unit. He told me to see if there was a recall.. Because the fix is very expensive... My vehicle is sitting and I'm scared to use it... Is there any help for this problem...

Lately, and intermittently, when the gas tank is 1/2 full or less and a sharp turn is made, the gas gauge goes to e, the low gas light comes on and the car will not go more than 20 MPH as if it is losing power. It's most scary when it occurs making a turn onto freeway entrance ramp and I am trying to get power to enter moving traffic. Typically, I have to pull over, turn the car off and restart to get the car to run normal.

When I drive my chevrolet trailblazer, the gas gauge is all over. I can have a full tank one minute, and half a mile down the road have 3/4 of a tank. Also it does the same thing when it has a quarter of a tank, it will say it has 1/4 of a tank, and a mile down the road it just drops and the low fuel light comes on. Also I can park the vehicle with about 3/8 of a tank, and start it later, and it says empty, and the low fuel light is on. We also have a 2004 gmc envoy that does the same thing. This has been an issue for both vehicles the entire time we have owned them. Both were bought in 2010. This occurs every tank of gas, and the actions are not always the exact same, so it is hard to tell if we actually need gas or not, sometimes they are actually almost out other times the have approximately 1/4 of a tank left. We have not done anything to correct the issue because we do not know what is causing it.

I saw an article in which you were testing trailblazers for faulty fuel gauges and it looked like it only spanned for 2005-2007, I have a 2002 trailblazers and have run out of gas now twice when it says I still have gas left, my light hadn't even turned on yet.

Bought 2002 chevrolet trailblazer which operated fine until 2 yrs ago. First, the speedometer goes nuts, the needle registers faster speeds than car is going. Some days it would work, some days it would not. Now it points past 120 MPH, directly downwards, stuck there and does not move at all. Sitting still in my driveway the speedometer shows its going over 120 MPH. The gas gauge goes nuts next. The needle goes past full and back around to the gas pump icon and stays there. The tachometer followed suit doing the same thing and indicating rpms past the 9000 range and doesn't settle back at zero with engine off. And now the temp gauge is showing 200 - 250 degrees when the engine is started. As far as I can tell the voltage and battery gauges are still showing normal readings - so far. Am I speeding, is my engine about to blow up, or am I going to run out of gas? I have no way of knowing if I am driving the speed limit or unknowingly speeding, no idea how much gas is in the tank, unaware that my engine is revving up into a dangerous range or about to blow up; or if my engine is dangerously overheating. I depend on the instrument cluster to alert me to those dangers. There should have been a recall on these failing instrument clusters a long time ago but although hundreds have complained gm says they won't fix this issue on the trailblazer. They don't care that we trailblazer owners must drive our vehicles without working instruments. This situation is dangerous.

Wife put fuel in the vehicle because it was down to a 1/4 tank and it is now the winter months, we dont like to be below half a tank. She drove it home and later that nite I got into the vehicle and noticed the gauge read empty and the light was on. I went to put fuel in it and at 5 dollars the tank for fuel. The gas gauge show empty upon even after filling the tank. The fuel level in the tank falls to a sufficient level to cause the gauge to display erratic and false readings. Nothing has been done to correct the failure which continues to be a constant problem. Fuel level now must be estimated through the use of the trip odometer the gauge reads full when you first start the vehicle and sometimes stays at full or reads empty with the light on. Called local garage they said sounds like a bad fuel level sensor common problem with chevy trailblazers from 02-09.

I have a 2002 chevy trailblazer that has had a host of problems to date. Now I am experiencing two more. Twice in the past few months I have been driving down the road with a 1/4 of a tank of gas or better when suddenly the car stalls, the gas gauge goes to empty. If I sit for a moment and then restart the car, the gas gauge goes back to 1/4 full or better. It is very frightening when the car just suddenly stalls out without warning. The other problem is the ABS system is now coming on when it should not. In the past two weeks I have had trouble bringing the car to a stop. The ABS comes on and disengages the brakes and the car skids ahead instead of stopping immediately. We had the same thing happen on our 2000 chevy silverado truck. It was fixed under recall, then started happening again after a couple of years. When we called chevy, they said they only fix under recall once. We were able to disengage the ABS. I have my service station looking now to see if we can disengage the ABS on the trailblazer too. These chevys are a real hazard!

There was a smell of gas, so I took it in to the dealer after they said it should be covered. They found rotted fuel module and hoses, removed fuel tank found fuel sending unit rotted,lines and hoses..replaced sending unit lines and hoses. Mdle kit 3.107 part# 19206122 ..pipe 3.163 part#15174333...pipe 3.163 part#15015511...sensor 3.107 part#16238399.. Now tell me it would have been covered if I brought it in earlier, I only just got the notice to have it looked at , so how could I have brought it in earlier.
